CCTV News:Yesterday (October 24th), the data released by the National Bureau of Statistics showed that in the third quarter, China’s consumer market generally recovered steadily, and market sales maintained growth.

The data shows that in the first three quarters, the total retail sales of social consumer goods was 32,030.5 billion yuan, up 0.7% year-on-year, with a growth rate of 1-mdash; It accelerated by 0.2 percentage points in August. Quarterly, it increased by 3.5% in the third quarter, and the recovery in the third quarter was faster than that in the second quarter. In September, the total retail sales of social consumer goods increased by 2.5% year-on-year, of which the retail sales of commodities increased by 3%.

Guo Liyan, Director of Comprehensive Situation Research Office of China Macroeconomic Research Institute:At present, the domestic consumer market is also maintaining a stable trend, especially the potential of consumer demand such as online social zero, some emerging consumption and some green and low-carbon consumption is further released, which also drives the development trend of consumer market to stabilize and recover.

In addition, since the third quarter of this year, the Ministry of Commerce has continuously promoted the implementation of the policy of green smart home appliances going to the countryside, promoted the resumption and development of catering, accommodation and other industries, and created new consumption scenarios through digital empowerment and business travel and cultural integration, giving full play to the role of important platforms such as the international consumption season and stimulating consumption vitality. Beijing, Shanghai, Guizhou, Jiangxi and other places have also promoted the upgrading of consumer demand by issuing consumer vouchers and government subsidies.

1-mdash this year; In September, Shanghai won the title of the first store capital in the mainland with the number of 703 first stores. Recently, a number of first stores have just appeared in the waterfront core area of Shanghai Suhewan. This urban complex, which is incarnated from the historical protection buildings such as the Shanghai-style Shikumen building "Shenyuli", presents a rambling consumption experience after ten years of renovation. Among more than 140 brands, more than 70% are the first stores in China, the first in Shanghai and the first in the region.

Near the end of the year, with the opening of several heavy projects, Shanghai will continue to develop the starting economy, brand economy and tax-free economy, and cultivate a number of leading local brands and new online brands. It is expected that Shanghai will introduce more than 800 first stores this year. In Guizhou, since the third quarter of this year, a total of 113 million yuan of travel coupons have been issued to consumers inside and outside the province, which has driven the growth of travel consumption. In Zunyi City, 304 enterprises or merchants involved in tourism, catering, accommodation and retail have been included in the designated use points of cultural travel coupons.

Not long ago, Mr. Chen saw a novel thing on the Discovery Channel: Americans put a blocking bed at the end of some airport runways, which actually prevented planes from rushing off the runways. On the TV screen, the materials paved at the end of the runway successfully prevented a Boeing passenger plane from rushing out of the runway, which protected the plane and ensured the safety of passengers.

The technology presented in the picture is called Engineering Material Arresting System (EMAS), which has long been monopolized by foreign companies. On July 12th, 2012, EMAS, developed by China Civil Aviation Science and Technology Research Institute and with completely independent intellectual property rights, officially passed the qualification examination of Civil Aviation Administration of China and was approved for engineering application. This is an important progress made by China Civil Aviation in the research and development of major systems related to flight safety, and it is also the second EMAS in the world to be approved by government civil aviation authorities. The achievement of this achievement will greatly reduce the cost of installing the system in airports, thus promoting the effective improvement of safety and security capabilities of many plateau airports and airports with special terrain in China.

How to stop the plane from running off the runway?

With the rapid development of the world’s civil aviation industry, the number of take-off and landing flights has increased significantly, and the number of aircraft rushing off the runway has shown an upward trend. How to avoid serious accidents after the aircraft rushing off the runway has become an important issue for civil aviation safety. In order to solve this problem, as early as the 1960s, the British began to research and develop related technologies to stop planes that ran off the runway, but failed to form products for various reasons. By the 1980s, the Federal Aviation Administration (FAA) and an American company began to jointly develop the EMAS system.

In fact, EMAS is a kind of foam concrete with specific mechanical properties, which is laid on the ground of the runway extension line with a thickness of several tens of centimeters to form an arresting bed. Its width is consistent with the runway, and its length is between tens of meters and more than 100 meters. Once the plane rushes out of the runway, it enters it, and the foam concrete is crushed under the rolling of the wheels, so as to absorb the kinetic energy of the plane, and on the premise of ensuring the safety of the plane and the people on board, the plane will gradually slow down and finally stop in the arresting bed.

In 1990s, FAA approved the design method of EMAS system. In 1996, the first trial laying was carried out at Kennedy Airport in new york, and three planes were successfully stopped. Subsequently, the FAA issued a license for it and promoted it in civil airports in need in the United States. Up to now, 55 sets of EMAS systems have been laid in 35 civil airports in the United States, and 8 planes have been successfully stopped. At the same time, the United States promotes the EMAS system on a global scale. In recent years, the system has been installed at Jiuzhai Huanglong Airport in Sichuan and Songshan Airport in Taiwan.

Can solve the problem of running off the runway.

Sichuan Jiuzhai Huanglong Airport was built by cutting mountains, surrounded by mountains on three sides. Due to the influence of complex terrain and high altitude, pilots often feel that the runway is short during the flight mission of Jiuzhai Huanglong Airport, especially in rainy and snowy weather. Once the plane lands and stops taking off, there will be back spraying, brake failure or rushing off the runway, and the consequences will be unimaginable. Therefore, in 2006, when Jiuzhai Huanglong Airport carried out the second phase expansion project, two sets of EMAS systems were installed at the north and south ends of the runway respectively.

In China, a considerable number of airports are built by cutting mountains, commonly known as "desktop airports". Although these airports have established runway-end safety zones according to the standards, there are often steep slopes or cliffs outside the safety zones. Once the plane rushes out of the runway-end safety zone, the tragedy of plane crash and death will inevitably be staged. In addition, some airports in Linjiang, Linhai and residential areas also have such problems.

With the rapid development of civil aviation in China, the number of flights has increased dramatically. In order to maintain the past safety level, we need updated safety measures. According to the statistics of ICAO, the number of runway accidents in the world ranks first in the statistics of civil aircraft accident types. In recent years, the number of incidents of civil aviation rushing off the runway in China also ranks first in the statistics of serious accident symptoms of civil aircraft. It can be seen that the installation of EMAS system in the airport where the safety zone at the runway end is not long enough can solve the problem of the plane rushing off the runway and obviously improve the safe operation level.

Technical problems of

Before the EMAS developed by the China Academy of Civil Aviation Science and Technology was approved by the Civil Aviation Administration of China, there were no similar products in China. If we want to install it in our airports, we need to face three problems: high product price, long transportation distance and difficult system maintenance.

It is reported that in 2010, Taiwan Songshan Airport plans to lay a set of this system, with a budget as high as NT$ 430 million. Compared with 2006, when the system was laid at Jiuzhai Huanglong Airport in Sichuan, the price has increased significantly. Such a high cost, even if the government gives most subsidies, it is difficult for small and medium-sized airports in China that need to install EMAS system most.

China needs its own EMAS system! In 2010, under the direction of Li Jian, deputy director of the Civil Aviation Administration, the Academy of Aeronautics and Astronautics organized a research and development team headed by its main leaders and attended by dozens of scientific research backbones, and relevant units in the United Nations invested tens of millions of yuan. After more than two years, the technical problems of material production and system design methods have been overcome. In order to effectively verify the performance of the product and the safety of the system, the Institute of Aeronautics and Astronautics designed and built a special test bench, conducted dozens of tests on the process of wheel rolling materials, and obtained a lot of valuable data, and finally established a set of perfect simulation calculation model and design method for the blocking process. The Academy of Aeronautics and Astronautics also specially purchased a Boeing 737 aircraft from Air China. Since the fourth quarter of 2011, it has carried out six large-scale real aircraft verification tests using the second runway of Tianjin Airport. The test results show that the EMAS system developed by the Institute of Aeronautics and Astronautics has an effective blocking effect and can ensure the safety of the aircraft and the crew.

Development prospect of

"For China’s civil aviation, the EMAS project is a brand-new and groundbreaking project, and only the United States has mastered this technology in the world. We don’t have any experience to learn from. Doing this project well is of great significance for China civil aviation to export standards to the international civil aviation community, to enhance the international status of China civil aviation, to enhance the safety margin of complex airports, and to build a strong civil aviation country. " Li Jian, deputy director of CAAC, has repeatedly emphasized the importance of China Civil Aviation in developing its own EMAS system.

The responsible person of Academy of Aeronautics and Astronautics (Beijing) Science and Technology Development Co., Ltd. revealed to the reporter that the successful research and development of domestic EMAS system has greatly reduced the laying cost, and provided reasonable engineering solutions for many plateau airports, airports with complex terrain and other airports that are difficult to extend the runway safety zone for special reasons. It has a very broad market prospect. Tengchong Airport has decided to install EMAS system, and many airports at home and abroad have also shown strong interest in this product. "We have more than 10,000 square meters of production workshop in Tianjin Airport Economic Zone, which can meet the environmental requirements for the production and maintenance of blocking materials, and can ensure the stability of material performance, and can produce one set of materials required for EMAS system every month."

This year, ICAO will put forward the standard of increasing the length of the safety zone at the runway end in the "International Standards and Recommended Measures" to reduce the serious flight safety accidents caused by running off the runway. However, due to geographical or other environmental constraints, many airports are difficult to meet the new requirements for the length of runway safety zone. EMAS has been written into Article 3.5.5 of Airport Design and Operation, Volume I, Annex 14 of ICAO Convention on International Civil Aviation, which has become an internationally accepted equivalent safety measure.

It is understood that although the price of domestic EMAS system has dropped significantly compared with similar products abroad, it is also a huge expense for many airports, especially small and medium-sized airports. In view of the purpose of laying EMAS system to improve the safety of airport operation, CAAC is working on formulating relevant subsidy policies to support the popularization and application of EMAS system.

　　● With the increasing popularity of self-help outdoor tourism, outdoor clubs, donkey friends clubs and go on road trip clubs frequently publish tourism products illegally through WeChat groups or QQ groups, publicize tourism routes, and receive citizens or donkey friends to travel.

　　● According to the relevant provisions of the Tourism Law, it is illegal for non-tourism enterprises and individuals to organize tourism activities by themselves.

　　● To completely eradicate the chaos of compulsory consumption of low-priced groups, we should rely on the law, increase punishment measures, and increase illegal costs and rights protection benefits.

　　□ Our reporter Zhao Li

　　"Since you have chosen a group with shopping links, you need to spend. What was your attitude towards me in the shop today? They’re all fighting guerrillas in there! Now get off and go to the store, and spend 20,000 yuan an hour … …” These words came from a female tour guide in Guilin.

　　This female tour guide brought a group organized by a beauty brand. According to tourists, "Give a product gift of 598 yuan to the travel agency", and you can go to Guilin from Hunan for free. On the last day of the trip, due to the high consumption of jade shops, the consumption of tourists did not meet the "psychological expectation" of the tour guide, so the above scene appeared.

　　After this compulsory consumption incident was exposed, the "low-priced group" once again attracted attention.

　　With the increasing popularity of self-help outdoor tourism, it is not uncommon for outdoor clubs, donkey friends clubs, go on road trip clubs, health care products sales enterprises and some training institutions to illegally publish tourism products, publicize tourism routes and receive citizens or donkey friends to travel through WeChat groups and QQ groups. According to the relevant provisions of the Tourism Law, it is illegal for non-tourism enterprises and individuals to organize tourism activities by themselves. However, according to the disclosure of relevant departments, many tourism activities attract consumers to join the group with "low-cost group tours" or even "zero group tours".

　　Through unannounced visits to such organizations that operate travel agencies without travel qualifications, the "Legal Daily" reporter found that many low-priced groups hide many tricks.

　　Ostensibly claiming not to be profitable.

　　In fact, hidden invisible consumption.

　　Recently, the reporter found a large number of QQ groups of related organizations through online search, and the format of group names is simple and consistent: ×× Outdoor Club. The reporter tried to apply to join the QQ group of these outdoor clubs as an outdoor sports enthusiast, but the pass rate was extremely low. Many applications for joining the group are "sinking into the sea" after they are issued. Some organizations directly rejected the reporter’s application for joining the group. For example, the ×× Shanshui Outdoor Club refused on the grounds that it was not introduced by acquaintances in the group after the reporter repeatedly applied for joining the group.

　　After many attempts, the reporter finally entered the individual group chat as an ordinary tourist, but after joining the group, the relevant responsible persons of these organizations will know the information of the new group users, such as "Who introduced them", "Where did they come from" and "What activities have they participated in before".

　　At present, the QQ group of "Beijing XX Outdoor Club" has 1436 people, and it promotes itself as an outdoor adventure club with the theme of mountaineering, hiking, camping, grassland riding, desert crossing, forest adventure, seaside swimming, photography, skiing, food, singing and making friends. The outdoor activities of this club are rich and varied, and most of them are short-lived, generally divided into one-day activities and two-day activities. The prices of short-term activities are generally low. Many one-day activities cost less than 100 yuan, and some two-day activities cost around 300 yuan. Take the one-day tour of Kingfisher Valley (located in Yanqing, Beijing) as an example. The activity cost is 65 yuan/person, including car charter, expressway fee, master fee and outdoor insurance. The activity was held on June 15th. By 15:30 on June 14th, more than 50 people had signed up.

　　The person in charge of the club explained to the reporter: "The expenses incurred by the activity are all AA system, without any additional benefits."

　　Two years ago, Ms. Wang, a citizen of Beijing, was dragged into an outdoor tour group, which published many low-priced tour routes. "People who organize tours say that if they don’t make money, they just organize everyone to go out to play." But Ms. Wang found that they "have not earned less money."

　　She once took part in a trip to Zhangjiakou, the cost was not enough for 300 yuan, but after getting on the bus, the hidden cost began. The organizer charged each tourist 50 yuan’s hard work and each tourist had to pay 10 yuan’s tea fee after the meal.

　　"Without a formal contract, it is too informal for such a tour group to transfer money through WeChat or pay by punching in." Ms. Wang said.

　　Some insiders also revealed to reporters that some outdoor clubs often attract friends to travel under the banner of non-profit, and the relevant personnel of the club make profits through the price difference. Because outdoor clubs don’t need to pay deposits and taxes like travel agencies, the operation of outdoor clubs is almost "zero cost".

　　The reporter interviewed Mr. Zhang, a staff member of a scenic spot who is in charge of receiving these clubs. He said: "The profits of related expenses can basically be divided into four or six with the organizers, and the commissions taken by general travel agencies or tour leaders are more."

　　The promoter declares that he is not responsible.

　　Tourists face greater risks.

　　Another "Beijing Lvyou ××" QQ group information shows that it was founded on October 23, 2015. At present, it has 2,862 members and has organized 44 activities. The organizer is "Beijing× Wolf Outdoor". The activity destinations are nearly Shuanglong Gorge, Pofengling and Dongling Mountain in the suburbs of Beijing, and as far away as Wuyuan, Dunhuang and Mohe.

　　According to the information of official website in Beijing × Wolf Outdoor, this organization is "dedicated to the tent rental industry in Beijing (Tianjin)", and its business scope mainly includes various outdoor goods rental businesses such as Beijing (Tianjin) camping tent rental, cotton sleeping bag rental, down sleeping bag rental, walkie-talkie rental and mountaineering bag rental.

　　The official website page of Beijing × Wolf Outdoor has also set up a column of "Journey Friends Activities". Open this page, which shows 70 pieces of relevant travel information released by this organization from June 6, 2017 to October 24, 2018. The reporter opened several links, most of which are related introductions such as tourist routes, itinerary planning and cost range, and occasionally a "disclaimer" is attached to the introduction. Disclaimer said: The initiator of the activity is only the contact person of the activity, and may not have participated in the training of outdoor leaders and field rescue. Although it is obligatory to help every participant, the initiator and leader of the activity are not responsible for any damage and consequences caused by participating in the activity — — Sign up voluntarily at your own risk.

　　Such a disclaimer can also be found in the details of the activities of the "Beijing donkey friends ××" QQ group.

　　The reporter found that the Mountain X Outdoor Club has also organized outdoor travel activities many times. According to a tweet from its WeChat WeChat official account on June 13th, the length of a seven-day trip is around 3,000 yuan per person. The travel routes include Jiaju Tibetan Village, Hailuogou Glacier, Daocheng Aden, Siguniang Mountain and other popular tourist attractions. The expenses include transportation (driver’s accommodation), accommodation (7 nights), tickets (Siguniang Mountain Shuangqiaogou, Jiaju Tibetan Village, Aden Scenic Area, Hailuogou), meals (breakfast in Danba), tour leader service and insurance. At the same time, it is stated that this line only buys travel accident insurance for players, excluding illness insurance and financial insurance. During the activity, if the financial loss occurs, it shall be borne by the players themselves; If financial losses are caused by personal reasons and need to be handled by themselves, a "departure agreement" needs to be signed.

　　Another go on road trip club, "X Ant go on road trip Club", also indicated similar terms in a go on road trip route push on June 14th. There is only a 500,000 yuan personal accident insurance in the travel expenses, and there is nothing else.

　　The leader of "Beijing × Star Club" told reporters that the price given by his club was "more cost-effective than the travel agency" and an extra accident insurance would be given. When the reporter asked whether to sign the relevant responsibility contract, the team leader replied: "Without signing the contract, the activities are voluntary."

　　Free travel has become a new trick

　　Force shopping to set a trap

　　It is worth noting that related disputes occur frequently.

　　In April 2017, Tian Congxin, an outdoor travel enthusiast, sued the organizer of the WeChat group tour and lost the case. The lawsuit originated in the summer of 2016. He and his friends joined the WeChat group of Happy Friends’ self-help tour and drifted to Daqinggou, Inner Mongolia. During the drifting, he accidentally caused an acute compression fracture of the lumbar spine. When he claimed compensation from the tourism organizer, he was rejected and sued the court. The court ruled that the organizer did not aim at profit, and because Tian Congxin was injured in the wrong sitting position, he took full responsibility.

　　On November 22nd, 2014, Zhang Bingyu followed the coaches of Qingdao Qianli Sports and Leisure Club Co., Ltd. to Jiuxian Mountain for altitude downhill outward bound training. During the descent, the protective rope was untied, and Zhang Bingyu fell from a height of about 30 meters above the ground and died. Yu, an employee of Qianli Sports Company, is the leader of this outward bound training. He knows Cao, whose net name is Mumu, from the outdoor sports group, who was temporarily hired by the company as the outdoor coach of this activity. According to the verdict, both Yu and Cao claimed that they did not have the qualification certificate to engage in downhill activities.

　　Organizations and individuals without tourism qualifications like this often offer various low-cost tours when operating travel agency business.

　　According to a Beijing resident who didn’t want to be named, his parents participated in a low-cost tour organized by the "outdoor donkey friends group" WeChat group. "Everyone has a one-day tour in 50 yuan and Yixing Zhuhai. My parents gather at 6: 30 in the morning and come back with big bags at 6: 00 in the evening. Bamboo shoots, bamboo chopping boards, activated carbon balls, dish towels, etc., spend hundreds of dollars and buy a bunch of useless things. "

　　The reporter interviewed Mr. Zhang, who used to be a tour guide. Mr. Zhang said: "In the tourism industry, low-cost groups basically imply consumption content, which is a default rule in the industry. But if you pay enough money reasonably, there may be only some slight guidance and no compulsory consumption. "

　　Ma Aiping, a professor at beijing international studies university Tourism Management College, thinks that the tour fee for four days and five nights is 598 yuan. If this fee includes food, accommodation and transportation, the price is obviously low, so travel itinerary includes three shopping items.

　　Liu Simin, director of the Tourism Research Institute of the Cultural and Creative Industry Research Center of Beijing Foreign Studies University, believes that there may be many reasons for being lower than the market price and operating cost, but if there are obvious shopping arrangements in the itinerary, it can basically be judged as unreasonable low-cost travel.

　　In 2017, the National Development and Reform Commission, in conjunction with the public security, industry and commerce, price and other departments, continued to carry out a number of actions to comprehensively rectify the order of the national tourism market, and seriously investigated and dealt with illegal acts such as "unreasonably low-cost travel" and "illegally operating travel agency business", and filed 2,595 cases, fined and confiscated illegal income of 33.26 million yuan, and revoked 45 business licenses.

　　Since then, although the related problems of some travel agencies have been contained and supervised to a certain extent, some organizations and individuals who operate travel agencies without tourism qualifications have begun to "move". There are also companies tying health care products during the "zero tour fee" tour.

　　Take Jiufang Joy as an example. This company is not qualified to organize tourism. In August 2018, a fire broke out in Beilong Hot Spring Leisure Hotel in Harbin, Heilongjiang, causing 20 deaths and 23 injuries. According to media reports, Jiufang Joy mainly sells health care products to middle-aged and elderly people, and customers with large consumption can get travel opportunities rewarded by enterprises.

　　According to the disclosure of relevant departments in Beijing, many tourism activities use "zero tour fee" as bait to attract the elderly to join the group, which hides multiple risks. Law enforcement officials of relevant departments in Beijing said that low-cost tours under the guise of "free tours" and "zero tour fees" are becoming more and more hidden, and the elderly often become the "hardest hit areas" for being deceived.

　　According to law enforcement officials, at present, "buying health care products for travel" and "buying wealth management for free travel" organized in the form of companies have become new tricks of criminals, and even some companies cheat in the name of recruiting "tourism experiencers", and applicants encounter compulsory shopping traps when traveling.

　　"WeChat friends circle, clubs, motorists’ clubs and other spontaneous group trips are often personal agreements, and there is no business license. Many irregular behaviors cannot be defined and are in a blind spot of supervision. This kind of tourism behavior is more prone to problems, ‘ Black tour guide ’ The phenomenon of slaughtering customers is even more difficult to detect, which brings difficulties to tourism law enforcement and evidence collection. " Beijing lawyer Liu Chengxian told reporters.　　

Google’s strongest AI model, which has attracted much attention and is considered by the industry to be the most likely to beat GPT-4, has finally appeared!

On December 6th, US Western Time, Google CEO Sundar Pichai and DeepMind Director Demis Hassabis jointly announced the official launch of Gemini 1.0 in official website.

Gemini is jointly created by several Alphabet teams such as Google Research and DeepMind. As a new powerful multi-modal artificial intelligence model, it can induce, understand, operate and combine different types of information. It can not only process text, images, video and audio, but also complete complex tasks in mathematics, physics and other scientific fields, and can understand and generate high-quality codes in various programming languages.

Pichai described Gemini as "our largest and most powerful AI model to date" and said that it has shown the most advanced performance in many leading benchmarks. "The first generation of Gemini 1.0 was optimized for different sizes, namely: Ultra, Pro and Nano. These are the first models to enter the Gemini era and the first realization of our vision when we established Google DeepMind earlier this year. "

At the Google I/O conference in May this year, Pichai spoiled the news that Google was developing Gemini. It is described as the "Next Generation Multi-modal Intelligent Network", which is designed for API integration. It is said that it has trillions of parameters like GPT-4, but its computing power is five times that of GPT-4, and it can perform more complex and diverse tasks.

To this end, Google also merged its two strongest artificial intelligence laboratories: Google Brain and DeepMind, led by Demis Hassabis, the former CEO of DeepMind, and invested hundreds of millions of dollars in research and development of Gemini.

Even sergey brin, the co-founder of Google, who has resigned for four years, has returned to the office of Mountain View in Silicon Valley to participate in the Gemini decision-making and join the LLM scuffle.

But just last week, The Information quoted people familiar with the matter as saying that Pichai recently silently canceled a series of Gemini public appearances that should have been held in California, new york and Washington, D.C., because it was found to be "unreliable in handling some non-English queries", which cast a gray color on the product launch process.

Perhaps to consolidate market confidence, early this morning, Gemini 1.0 suddenly made its grand debut, appearing in the public’s field of vision and quickly occupying the front pages of major scientific and technological media.

So, what is the strongest artificial intelligence model that Google is betting on the whole army?

Hassabis, head of DeepMind, called Gemini their most flexible model, which can run efficiently on all kinds of devices from data centers to mobile devices.

In order to achieve this extensibility, Gemini 1.0 has designed three versions with different functions and sizes:

Gemini Nano —The most efficient model on the end-side equipment. Designed for smart phones, it can perform efficient AI processing tasks without connecting to an external server. Now it has been integrated into Pixel 8 Pro, which can support the function of "summarizing text" in recording applications and the function of "intelligent reply" in Gboard. Starting with WhatsApp, it will be extended to more applications next year.

Gemini Pro —The best model for various tasks running in Google data center. Support the latest version of the AI chat robot Bard from today. It can respond quickly and understand complex queries, which is the biggest upgrade since Bard was introduced. At present, it provides English services to more than 170 countries and regions, and plans to support new languages and regions in the coming months, and apply them to more Google products such as search, advertising, Chrome and Duet AI.

Gemini Ultra -The largest and most powerful model, dedicated to highly complex tasks, will be provided to developers and enterprise customers early next year after completing the current testing phase. At that time, an updated version of Bard Advanced based on Gemini Ultra will be launched.

In terms of model architecture, Gemini still uses Transformer architecture, adopts an efficient attention mechanism, and supports the context length of 32k.

Google confidently said that after rigorous testing and performance evaluation of the Gemini model, from natural image, audio and video understanding to mathematical reasoning,Among the 32 academic benchmarks widely used in the research and development of large-scale language models, the performance of Gemini Ultra has exceeded the most advanced level represented by ChatGPT at present.. Before the release of Gemini, Google conducted a series of tests to evaluate it with standard industry indicators.

In the MMLU test, the score rate of Gemini Ultra is 90.0%, which is higher than that of GPT-4 (86.4%), making it the first model to surpass the performance of human experts. The MMLU test covers 57 subjects, including mathematics, physics, history, law, medicine and ethics, and aims to evaluate the model’s understanding and problem-solving ability in the global knowledge field.

In Reasoning, Math and Code, except HellaSwag, which lags behind GPT-4 by 87.8%, others include challenging math problems such as multi-step reasoning, algebra/geometry/pre-calculus and so on.

In terms of multimodal capability, Gemini Ultra achieved a SOTA score of 59.4% in the new MMMU benchmark test, which exceeded the 56.8% of the multimodal version GPT-4V of OpenAI. This benchmark test spans many different fields and requires precise reasoning for many tasks.

In the image benchmark test, even without the assistance of Object Character Recognition (OCR) system, the performance of Gemini Ultra is better than all previous models only by analyzing pixel information. In audio testing, the scores of automatic speech recognition and automatic speech translation of Gemini are higher than those of Whisper system connected to GPT-4.

Hassabis said that this highlights the superiority of Gemini’s native multimodal. Up to now, the usual way to create multi-modal models is to train individual components of different modes independently, and then splice them together to try to simulate some functions.

Although such models can sometimes effectively perform specific tasks such as describing pictures, they often perform poorly in more conceptual and complex reasoning.

Gemini was originally designed in a native multi-modal way, and was pre-trained in different modes from the beginning using TPUs v4 and v5e chips designed by Google.. Then it is fine-tuned with more additional multimodal data to improve its performance.

This method enables Gemini to understand and reason all kinds of input content more naturally in the initial stage, and its ability in almost all fields has reached an unprecedented advanced level.

First of all, Gemini has complex multi-modal reasoning ability, which can help to understand complex written and visual information and discover indistinguishable knowledge content in massive data.

For example, it is instructed to filter irrelevant papers through the natural language prompt, or extract key data through reading. With a lunch break, Gemini can help you extract 250 document points from 200,000 papers, and further transform the data into any required chart form. This will greatly help to achieve innovative breakthroughs in science, finance and other fields at a digital speed.

The trained Gemini can obviously recognize and understand text, image and audio data at the same time, better understand subtle information and answer questions related to complex topics. This makes it especially good at explaining reasoning in subjects such as mathematics and physics. In the example, the staff showed that Gemini can check handwriting physical mistakes and explain the correct way.

In order to show the multimodal capabilities of Gemini more intuitively, Brother Chai released a video in X, saying that "the best way to understand the amazing potential capabilities of Gemini is to look at their practical applications".

In the video, Gemini taught the staff the pronunciation of "duck" in Mandarin according to the instructions, and also explained the Chinese tone.

The staff also gave Gemini a demonstration of interaction only in Chinese. By asking about the indoor light in a picture, Gemini is asked to give the orientation of the apartment in use. Gemini answers in Chinese and guesses that the room faces south. Circle a plant in the photo and ask what kind of lighting it needs. gemini then explains the plant species and lighting requirements. The whole process is as smooth as the mother tongue, which shows that Gemini is outstanding in multilingual environment, which is no less than GPT-4.

In addition, Gemini can understand, interpret and generate high-quality codes of the most popular programming languages in the world, such as Python, Java, C++ and Go. The ability to achieve cross-language work and handle complex information makes it one of the world’s leading basic coding models, helping programmers to use the powerful AI model as a collaborative tool to design applications.

For developers, starting from December 13th, Gemini Pro can be obtained through the Gemini API in Google AI Studio or Google Cloud Vertex AI. Android developers can also use Gemini Nano, the most efficient model for end-to-end tasks, through AICore.

Looking back on the development of Google’s big model all the way, compared with the continuous and rapid update of OpenAI’s "Wang Fried", Microsoft always seems to be one step behind when it integrates various AI functions of GPT into core products and pushes them to customers. When Bard, a chat robot, was released in February this year, it got off to a bad start, and the market value evaporated by 100 billion dollars overnight with a factual error. Benchmarking Microsoft Copilot’s Duet AI work suite, the market response was moderate, and the financial performance of cloud services also lost to Microsoft.

Especially after the internal friction caused by the reorganization of Brain and DeepMind teams and the loss of senior talents to OpenAI, Google’s AI battle is even more exhausted.

However, this is, after all, an AI pioneer who contributed to Transformer’s pioneering masterpiece Attention is all you need and the landmark artificial intelligence program AlphaGo, and inspired the subsequent development of many large models including ChatGPT. No matter from the technical genes, training data, capital and infrastructure, it should have one of the best strengths.

The release of Gemini is regarded by Google as the most critical technological innovation in the past decade. Can it make Google rally, beat OpenAI and regain the throne of the big model stadium?

Will the AI competition pattern be reshaped after Genmini Ultra comes out next year?

And, has everyone tried the new Google Bard? How do you feel?

　　Xinhua News Agency, Tehran, September 21st: Talk about "America can’t be trusted" in the eyes of Iranians.

　　Xinhua News Agency reporter Gao Wencheng

　　Iranian President Leahy made it clear in an interview with the American media a few days ago: "We can’t trust the United States." This sentence is not only his personal opinion, but also the consensus of Iranian society. From a government spokesman to an ordinary librarian, Iranian society now widely believes that — — "the United States cannot be trusted."

　　The formation of this social consensus is closely related to the United States’ treachery and arrogance on the comprehensive agreement on the Iranian nuclear issue. In July 2015, after 10 years of arduous negotiations, Iran reached the the Iranian nuclear deal with the United States, Britain, France, Russia, China and Germany. However, in 2018, despite the opposition of the international community, the United States unilaterally withdrew from the Iranian nuclear deal and once again held high the sanctions stick to "exert extreme pressure" on Iran.

This is the scene of the new round of political director-level meeting of the Joint Committee of the Iranian Nuclear Comprehensive Agreement, which was filmed in Vienna, Austria on June 12, 2021. Xinhua News Agency (Photo courtesy of the EU delegation in Vienna)

　　The United States’ wanton breach of contract and indiscriminate sanctions have caused great harm to Iran’s development. After the Iranian nuclear deal was reached, the United States lifted sanctions against Iraq, and Iran’s daily average oil export once reached 2.5 million barrels, with a record economic growth rate of 13.6%. However, after the United States unilaterally broke the contract and re-imposed sanctions, Iran’s oil exports once plummeted to only 100,000 barrels per day, and the economy shrank sharply year after year.

　　Affected by US sanctions, the Iranian currency Rial has depreciated sharply in just a few years. Before the sanctions were restarted, more than 30,000 rials could be exchanged for 1 US dollar, but now it takes 30 Wan Li rials to exchange for 1 US dollar. The import and production costs of Iranian goods have increased significantly, and the shortage of materials has led to soaring prices and difficult people’s livelihood. Since 2018, the overall price in Iran has increased by about 85%, and food prices have doubled. Many Iranian families can’t make ends meet, and their lives are very tight. During the Chinese New Year, many Iranian children can’t put on new clothes, and many housewives have to think about buying a piece of meat for half a day.

　　The pain of people’s livelihood has caused Iranians to pay close attention to the Iranian nuclear talks and look forward to the early lifting of sanctions. However, the indirect negotiations between Iran and the United States on the Iranian nuclear deal’s resumption of performance have been going on for nearly a year and a half, with ups and downs in the middle, and no results have been achieved so far. The current U.S. government said one thing and did another. Although it verbally expressed its willingness to return to the Iranian nuclear deal, it inherited the previous government’s policy of "extreme pressure" on Iraq, and even during the negotiations, it continued to raise the threat tone and increase the sanctions against Iraq.

　　The current American government’s words and deeds are different, which has deepened the Iranian society’s cognition that "the United States cannot be trusted." Leahy said that if Americans want to reach an agreement, "why should they impose new sanctions on Iran during the negotiation?" Because the United States reneges on its word and has a bad track record, Iran is now very cautious in negotiations. The Iranian side has repeatedly asked the US to make a guarantee that it will not violate the contract again. Mohammad Marandi, consultant of the Iranian negotiating team, made it clear that Iran believes that corresponding provisions should be set, and if the United States breaches the contract again, it must pay the price.

　　Iranian society believes that "the United States cannot be trusted" is a silhouette of the increasing bankruptcy of American national credibility in the international arena. A number of polls show that the global influence of the United States is generally declining. In order to safeguard hegemonic self-interest, the United States has repeatedly broken the contract and "retired from the group" and provoked conflicts and confrontations. Although the United States often pretends to be so-called "democracy" and "human rights", it is hard to hide the evil consequences of its perverse actions on other countries and even the whole international community.

　　Fatty liver is becoming more and more common, and medical research suggests that it is closely related to diet. So, is there any way to "eat back" the "fat" liver that has been eaten?

　　"Yes!" Chen Zexiong, a famous Chinese medicine practitioner in Guangdong Province, pointed out that proper diet can really help the liver "slim down", which is also the treatment to eliminate the cause of fatty liver. However, people with "fat" liver should eat according to syndrome differentiation, and even cooking oil is particular. Experts also give three prescriptions: porridge, soup and tea to help patients with fatty liver to eat diet every day.

　　Medical Guidance/Provincial Famous Chinese Medicine Doctor, Chen Zexiong, Chief Physician of Chinese Medicine Department of the First Affiliated Hospital of Sun Yat-sen University, and Sun Baoguo, Deputy Chief Physician of Chinese Medicine Department of the First Affiliated Hospital of Sun Yat-sen University.

　　Text/Guangzhou Daily All-Media Reporter He Xuehua Correspondent Peng Fuxiang

　　Fatty liver is mostly physical examination, and it is found that 30% to 40% is due to obesity.

　　Two days ago, an old acquaintance and classmate came to Sun Baoguo’s clinic. She was blessed and anxious. It turned out that the old classmate was found to have fatty liver in the physical examination of the unit. "I heard that it might be cirrhosis and liver cancer, which scared me to worry about what to eat and drink!" The old classmate said.

　　There are quite a few such cases. Most patients with fatty liver only find problems during physical examination.

　　This is because most of mild fatty liver has no obvious symptoms, or only a sense of fatigue, which is easy to be ignored. However, if it develops into moderate to severe fatty liver, there will be loss of appetite, fatigue, nausea, vomiting, weight loss, right hypochondriac or right upper abdominal pain. Moreover, if the treatment of simple fatty liver is neglected, it can develop into steatohepatitis and cirrhosis for a long time.

　　Fatty liver, as its name implies, is the excessive accumulation of fat in the liver. Medicine believes that it can be caused by many causes and diseases, mainly related to obesity, diabetes, alcoholism and so on. According to relevant literature reports, simple obesity accounts for 30%~40% of the causes of fatty liver, and many patients with fatty liver have high-fat and high-cholesterol diets, which suggests that the formation of fatty liver is closely related to diet, and diet may be the direct cause of disease in the general population.　　

　　Dietotherapy can eliminate the cause of fatty liver

　　Finding and eliminating the cause is the fundamental method to treat fatty liver, such as adjusting diet structure, losing weight, abstaining from alcohol and treating the primary disease.

　　Professor Chen Zexiong pointed out that a reasonable diet is of great significance to the prevention and treatment of fatty liver, especially for patients with simple fatty liver, most of them can be recovered through reasonable diet and exercise. Therefore, if you have fatty liver, don’t be afraid and worried. It is better to actively try diet therapy and "eat back" the problems you have eaten.

　　Then how to treat fatty liver?

　　Traditional Chinese medicine believes that this disease is caused by improper drinking and eating, invasion of human body by dampness, emotional disorder, or chronic illness and physical weakness, which leads to poor qi movement, and the combination of dampness, phlegm and blood stasis, which is blocked in the blood vessels and meridians of the liver. Therefore, regulating qi-flowing, eliminating phlegm-dampness, promoting blood circulation and removing blood stasis, and clearing the liver and gallbladder are the main methods for treating this disease in traditional Chinese medicine. The choice of daily diet for patients with fatty liver should also follow this principle. While paying attention to the color, smell and taste of food, try to choose foods that meet the actual needs of individuals.

　　List of foods to help the liver "lose weight"

　　Foods with fatty liver preventing and treating effects and nutrition metabolism improving effects;

　　Patients with fatty liver who are uncomfortable with the right hypochondriac rib (that is, the right chest from the armpit to the sternum) and easy to get angry can eat more vegetables, chrysanthemum, tomatoes, shepherd’s purse, etc., which can clear away heat and cool the liver;

　　Patients with bad breath, constipation and fatty liver who overeat greasy food can eat more vegetables and fruits rich in vitamins and cellulose, such as radish, bamboo shoots, wax gourd, loofah, celery, cucumber, water chestnut and hawthorn fruit, which can clear away heat, promote bowel movement and facilitate urination;

　　Fatty liver patients with physical weakness can choose low-fat and high-protein foods such as pork lean meat, pigeon meat, rabbit meat, beef lean meat, skim milk, soybean milk, etc., which can tonify liver and kidney, replenish qi and nourish blood.

　　Food unsuitable for patients with fatty liver:

　　Pig fat, goose, duck eggs, animal oil, animal viscera and animal brain have high fat content; Crab, crab roe, squid, cuttlefish, clam meat and anchovies are high in cholesterol, so it is advisable to eat less or not. Because sugar will turn into fat in the body, which will aggravate fatty liver, it is better to eat less high-sugar foods such as litchi, longan pulp, candied fruit, preserved fruit and sugar.

　　Selection of staple food and oil:

　　It is suggested that fatty liver patients should choose vegetable oils such as vegetable oil, sesame oil, cottonseed oil and peanut oil, because they contain more unsaturated fatty acids and have the effect of lowering blood cholesterol. The staple food can be low-sugar foods such as corn flour, buckwheat flour, oat flour, bean flour and other products. These foods are coarse grains, which can reduce qi and broaden the intestines and cleanse the greasy stomach.

　　One porridge, one soup and one tea are most suitable for liver "fat"

　　Patients with fatty liver in daily life can also choose medicated diet for conditioning:

　　Hawthorn Carassius auratus soup: Take 30g of raw hawthorn, one crucian carp, 10g of immature bitter orange, appropriate amount of ginger and water, and drink the soup after cooking. Regular administration of this decoction can promote blood circulation and qi circulation, and has a certain effect on hypochondriac swelling pain or acupuncture-like pain, or hepatomegaly and purple tongue.

　　Pueraria flower tea: 15g of Pueraria flower, 10g of Salvia miltiorrhiza, 4-5 tablets of Ilex kudingcha, appropriate amount of water, boiling and simmering for 30min, and taking the juice as tea. Used for long-term alcoholism and mutual stagnation of dampness and blood stasis.

　　Codonopsis pilosula millet porridge: 10 grams of Codonopsis pilosula, 10 grams of Poria cocos, 20 grams of lentils, boiled for 30 minutes with appropriate amount of water, added with 100 grams of millet, and cooked with slow fire. For people with weak temper, such as listlessness, pale complexion and loss of appetite, this porridge can be taken frequently.

　　Special reminder that dietotherapy doesn’t work, hurry up with medication.

　　Experts pointed out that while adjusting the diet structure, patients with fatty liver should also take appropriate exercise to keep their mood comfortable, which is helpful for the treatment of fatty liver.

　　Special reminder, for those who have the primary disease or the above methods can not be effective, they must go to a regular hospital to find a specialist to deal with it, and cooperate with drug treatment to avoid delaying the illness.

　　　　For today’s smart vendors, it is hard to imagine what is more important than diversified development. A few years ago, the mobile phone was still just a device for talking to us, but with the popularity of intelligent platforms, the mobile phone has changed from a communication device to a multi-functional intelligent terminal. Nowadays, in order to get rid of the homogenization of Android platform, Android manufacturers spare no effort to develop more potential of mobile phones. At this time, we will find that those manufacturers who can integrate the technologies of multiple product lines highlight more advantages than those who simply make mobile phones.

　　　　When CEO Kazuo Hirai took office, we first heard the strategy of "One Sony". This is not the first time for Sony to integrate the technology of other product lines into mobile phones, just like the Walkman series and Cyber-Shot series that we once amazed. This time, Sony once again applied its camera technology to smart phones, and L39h (hereinafter referred to as Sony L39h) became the first product under the concept of One Sony. Just like the words in Kazuo Hirai’s mouth after the release of several DCDV devices in Berlin, "The next product can present the best part of Sony to you at one time."

G lens Sony Xperia comprehensive evaluation

　　　　In terms of configuration, Sony L39h has adopted today’s flagship configuration without any accident. After the slow pace of last year, Sony’s flagship product has finally accelerated its pace in hardware this year, and has always maintained the strongest configuration at the same level as flagship models of other international brands. Like the Sony L36h released at the beginning of this year, Sony L39h uses a 1080p display screen. However, due to the overall improvement in photographing this time, the photosensitive element has also increased to 1/2.3 inch, so the overall thickness and length and width of the fuselage have increased to some extent in Bisogni L36h. The fuselage circumference of this model is 144× 74× 8.5mm, which will be thicker in the hand than that of Bisogni L36h, but relatively, it feels more comfortable because the frame adopts a brand-new flat cutting angle.

Sony’s first image flagship 5-inch 1080p Sony L39h

　　　　Sony L39h is equipped with 2.2GHz MSM8274 Opteron 800 quad-core processor and GPU Adreno 330 image processor, and its outstanding performance is beyond doubt. At the same time, Sony L39h has also continued Sony’s waterproof and dustproof features, reaching IP55/58 level. This means that the phone has a built-in dustproof and waterproof design, that is, all ports and covers are closed, and the phone can be dustproof and can be placed in the deepest 1.5 meters of clean water for up to 30 minutes. Of course, taking photos is the biggest improvement of Sony L39h this time, and we will show it in detail later.

　　　　Regarding the screen that most users pay attention to, the performance of the IPS screen in China made us feel amazing, but this amazing performance did not continue to the Sony L39h used in our evaluation. In other words, Sony L39h, like Sony XL39h, brings users a more vivid and clear visual experience through TRILUMINOS mobile display technology and X-Reality fast image processing engine, but this is only when we watch the screen from the front. When we look at the screen of Sony L39h from the side, the visual effect is still the same as Sony L36h. This really makes us regret. I wonder if the retail version is the same as the prototype used in the evaluation.

　　　　Every year, the flagship product has maintained a high degree of consistency in appearance. In the previous interview, Mr. Morinuma, the designer of Sony L39h, explained that this is first to maintain the continuity and consistency of the design language. But also, each product will be fine-tuned in design and introduce a brand-new design based on the actual experience of users. This time, Sony L39h, like Sony L36h, has adopted a plane-like fuselage line, the camera has no protrusion, and the front and rear sides are also protected by double-sided glass, which gives people a high-end and exquisite impression visually.

2 megapixel front camera

Keys are still built into the screen.

　　　　The screen size of Sony L39h is consistent with that of Sony L36h, which means that the change in the length of the fuselage mainly comes from the extension of the upper and lower ends of the screen. The place above the SONY English logo near the frame that looks like a groove is both the receiver and the breathing light. When charging or resting, the lights here will light up. In addition, the front camera located next to the logo has not changed, and it is still 2 million pixels, which is enough for self-timer and can also record 1080p video. At the bottom of the screen, we obviously feel that the "chin" Bisogni L36h of Sony L39h is getting longer, but the Android buttons are still built in the screen. Many netizens wondered why Sony didn’t put the Android button on this slightly longer chin. Although we didn’t get an official explanation, after actual operation, we found that with the growth of smart size, it is actually very difficult for us to hold the Android button on the chin of a mobile phone with a size of 5 inches or more. In other words, actually putting the buttons on the screen is more user-friendly in our actual operation, and it will be better if Sony can let users choose to hide or display these three buttons by sliding up and down in the future.

MicroSIM card slot on the right side and power button and volume button.

The bottom of the right side is provided with a hanging hole and a camera shutter.

　　　　Sony L39h adopts a complete seamless design, and uses aluminum frame to make the mobile phone more durable. At the same time, it also uses this frame as an antenna through brand-new technology, which solves the disadvantage of poor call signal of metal body. Sony L39h still designed the main card slots and buttons on both sides of the fuselage, and attached dust plugs, thus maintaining a high degree of visual integration with the frame without affecting the appearance. On the right side, there is still the microSIM card slot, power button and volume button, and at the bottom, Sony L39h has added a photo shutter button, which is also convenient for users to take photos through the physical shutter button when they can’t touch the screen underwater.

The microSD card slot and data interface on the left side of the fuselage support MHL data transmission.

Metal contact for connecting magnetic attraction waterproof charging base

　　　　The design of the left card slot of Sony L39h is somewhat different from that of Sony L36h. The positions of the microSD card slot and the data interface are upside down, with the microSD card slot at the top and the data interface supporting the transmission of microUSB and MHL at the bottom. Sony L39h also has an official standard waterproof charging base, and the metal contact below the data interface is used when connecting with this base.

　　　　Another subtle change of L39h fuselage lies in the design of earphone hole, which is located at the top of the fuselage, but it is not equipped with dust plug like Sony L36h. Of course, users don’t have to worry about water coming into this earphone hole. Nowadays, the application of waterproof nano-coating technology is not uncommon. Personally, I think Sony chose to equip the interfaces on both sides of the frame with dust plugs, mainly for aesthetic considerations. In practical use, especially for people who listen to music on their mobile phones every day, the dust plug in the earphone hole is indeed redundant, and this design is just right.

The earphone hole at the top is not equipped with dust plug this time.

The bottom is almost a speaker, so it won’t block when you hold it.

　　　　Another change comes from the position of the Sony L39h speaker. Sony L36h designed the speaker at the lower right side of the fuselage, which is the position of the Sony L39h camera shutter button. In actual use, if we hold the mobile phone in one hand with the right hand, the speaker will be easily blocked, and the movement of the hand will directly cause the sound of the speaker to be loud and small. This time, the speaker is designed at the bottom, which is a good solution to this problem. This change is still very intimate.

The back is still a whole glass design.

Main camera marked with G and 1/2.3 inch sensor

XPERIA capital logo at the bottom of the back

　　　　The back of Sony L39h’s fuselage is still full of glass, and the explosion-proof membrane is also pressed for protection when it leaves the factory. This design is really beautiful, but it is also easy to be contaminated with fingerprints. Relatively speaking, white is the color with the least fingerprints among the three colors of black, white and purple. Sony’s English logo is located in the center of the fuselage. Above is the mark of NFC position, and below is the word XPERIA in all capitals. This time, it seems to emphasize the advantages of taking pictures. It is rare for Sony to mark the G word of G lens next to the camera, as well as the camera pixel size of 1/2.3 inch sensor and 20.7 million pixels. It can be seen that Sony is indeed full of confidence in taking pictures of this product.

　　　　L39h is equipped with Android 4.2 jelly bean system, but it does use a slightly different UI from Sony L36h upgraded to Android 4.2. Of course, the difference between the two is not very huge. At least as far as the main interface and the unlocking interface are concerned, we have not found any difference in the operation mode. At most, the buttons that enter the application interface are designed differently.

　
Sony L39h Home Screen and Unlocking Interface

　
The theme of Sony L39h (left) has changed a lot from Sony L36h.

　　Like the Sony L36h, the Sony L39h can change the theme and add widgets and applications to the home screen by pressing and holding the home screen. By contrast, we can see that the theme of Sony L39h has changed obviously. At the same time, when we do this operation, the presentation form of the thumbnail of the upper home screen is also different, from white translucent to black translucent, which is more visually recognizable.

　
The menu style of Sony L39h (left) application interface is also different from Sony L36h.

　
Sony L39h (left) drop-down notification bar can display more shortcut buttons.

　　　　In the application interface and drop-down notification bar, Sony L39h has also changed. In the past, we need to click the button in the interface to call out the menu of unloading and sorting, but in Sony L39h, we just slide the screen to the far left and call out the corresponding menu. When we drop down the notification bar, we can see that the shortcut operation buttons of Sony L39h have been expanded from one row to two rows, but we still don’t support setting the buttons independently.

　
Sony L39h (left) changed to X-Reality for mobile.

　　　　The change of display interface is also obvious. One of the highlights of Sony L36h is that you can manually adjust the white balance settings, but in Sony L39h, the white balance option has been cancelled. But in contrast, in Sony L39h, the original Bravia Engine 2 was replaced by the latest X-Reality for mobile, and a new backlight optimization mode was added. X-Reality for mobile can make the picture presented to us clearer and more vivid, which can be regarded as another upgrade of Bravia.

　　　　In terms of function, there is not much innovation in this L39h, which continues the characteristics of Sony L36h and the middle school, such as sketch function. On the whole, Sony L36h put all the emphasis on taking pictures. Let’s take a look at how the new camera flagship of this Android platform performs.

Sony L39h, the biggest change is taking pictures.

　　　　Sony L39h has three key words in taking pictures, namely, 1/2.3-inch large Exmor RS layered image sensor, Sony G lens, and mobile BIONZ image processor. So how does Sony explain these three keywords?

　　　　The main camera of Sony L39h has been achieved, and the 1/2.3-inch Exmor RS laminated sensor can capture more scene light and make full use of the powerful function of camera lens to shoot ultra-high resolution images. The sensor has higher sensitivity, which can reduce noise, ensure smooth and clear images, and completely reproduce all wonderful details with higher fidelity. Sony G lens is a unique feature of Sony used in cameras, which has extremely high in-focus imaging quality. In addition to sharpness, it also has excellent light gathering ability. The F2.0 large aperture 27mm wide-angle lens adopted by Sony L39h can perform better in low light and capture more light.

　　　　In addition, in order to get better detail reproduction effect, Sony L39h also uses the powerful algorithm of Sony mobile BIONZ image processor to make the shooting picture more vivid and realistic. Ultra-high pixel resolution, automatic exposure and automatic white balance ensure the accurate presentation of the colors captured by Sony G lens-while achieving brightness balance, the colors are enhanced and reproduced with rich texture layers and layers, and the effect is the same as that seen by the naked eye. The combination of 1/2.3 inch 20.7 megapixel mobile Exmor RS layered sensor and mobile BIONZ image processor can also eliminate noise.

　　　　Finally, a new breakthrough of Sony L39h lies in the zoom of 3x clear image. When shooting at a long distance, the high-resolution sensor and the mobile BIONZ image processor can provide users with an optical zoom of 81mm, bringing the picture closer, and the details are still clear. Of course, as our text shows, it is limited to zoom 0 distortion within 3 times.

Sony L39h camera basic function

Sony L39h camera interface

In advanced automatic mode, the current scene mode will be displayed in the lower right corner ("soft capture" in the picture).

Long press shutter continuous shooting needs to be set in advanced automatic mode.

　　　　In fact, the basic camera function of Sony L39h is not much different from that of the past. However, it should be noted that there were various scene modes for us to choose from in Sony in the past. However, in Sony L39h, users can’t manually select the scene mode, but can only automatically identify the most suitable scene mode at present through the "advanced automatic" mode. In addition, the function of continuous shooting requires us to open the option of long-press the shutter button continuous shooting in the setting menu of "Advanced Auto" mode. Frankly speaking, the setting of these small options is actually more complicated than before.

　　　　After reading the basic functions, let’s take a look at the featured functions in L39h. Obviously, the time shift function of Timeshift Burst, the information acquisition function of Info-eye and the shooting function of AR augmented reality are the three most interesting camera functions in Sony L39h. How to play these functions?

Info-eye function in Sony L39h

　　　　The function of Info-eye is very interesting, and we can use it as a new way to get information. Info-eye can shoot landmark buildings, characters, red wine, business cards and other formulated objects. As long as we shoot through the camera viewfinder, we can immediately see the relevant information obtained by networking.

Timeshift Burst function, the user can capture it without fail.

　　　　Timeshift Burst’s time shifting function is actually to help users capture the best photos through ultra-high-speed continuous shooting. When the shutter is pressed, the Timeshift Burst time shift function will completely record 61 images in one second before and after the shutter. After taking pictures, we just need to dial the photos in the turntable and choose the best one to save.

Seven AR Augmented Reality Scenes

　
"Diving" and "Masquerade Ball" Scenes

　　　　The fun photo function of AR augmented reality is very suitable for users with children at home, or for multi-party to enliven the atmosphere. Sony L39h provides us with seven interesting AR scenes. When the face is recognized, Sony L39h will automatically add funny accessories such as hats and glasses to the face, and the addition of these AR animations is also very intelligent. When there is a plane in the picture, these animations will be placed on the plane, and there will be no unscientific pictures such as corals floating in the air or mushrooms appearing overhead.

Sony L39h still comes with 9 kinds of filters.

　　　　In the Sony L39h, nine kinds of camera filters used in Sony are retained, so users can take photos of various small and fresh literary styles directly through the camera in their mobile phones according to their own needs.

　　　　　After introducing the innovation of L39h camera technology and the breakthrough of camera function, we should also take a look at the photo proofs of Sony L39h. Because Sony L39h is a product that has made a big breakthrough in taking pictures, we also chose the flagship Sony L36h at the beginning of this year for comparison. Although there is a big difference in the number of pixels between the two, it is really unfair to compare them, but it is also part of Sony L39h’s photo improvement. We will present the proofs in outdoor, indoor, macro and low light, and the AR proofs of Sony L39h will also be attached.

Sony L36h outdoor proofs (under the sun)

　　　　The outdoor proofs in the daytime are divided into two situations, one is that there is enough light in the sun, and the other is that the shade is relatively backlit. Sony L39h’s color in the sample under the shade of the tree is more realistic than Bisogni L36h’s, and the degree of protection is higher. However, in a sunny environment, perhaps due to the large amount of light entering Sony L39h, the overall color tone is a little whiter than Sony L36h, but at the same time, the details of trees in the distance are richer.

Sony L39h/ Sony L36h indoor proofs

　　　　We took a lot of indoor proofs, and chose the shopping mall as an environment with complicated light for comparison. We can clearly see that Sony L39h’s ability to aggregate light is much better than that of Bisogni L36h. At the same time, Sony L36h appeared obvious color cast when shooting indoors, while Sony L39h restored the real color in place and controlled the noise well.

　　　　Next, we will challenge the low light and macro of L39h and the effect of AR photography. In low light, we chose indoor and outdoor situations. Strictly speaking, the two macro photos were also taken in low light environment.

Sony L36h Weak Light Proof (Indoor)

　　　　Sony L39h did a good job in the part of taking pictures in low light. First of all, while improving the brightness, the color is more natural, and there is no loss of some details. The picture of the building was taken at sunset in the evening, and both Sony L39h and Sony L36h automatically improved the overall brightness of the picture. However, we can find that the billboard in the Sony L36h sample has obvious details missing, and the building itself also appears white and the contrast is not strong enough. When shooting at night after the sky is completely dark, although the performance of Sony L36h is still satisfactory, it is obvious that there is a certain gap in saturation compared with Sony L39h, and the color of the picture is not vivid enough. In the last indoor low-light shooting session, the proofs of the two devices have obvious differences in fineness. Because Sony L36h will smear seriously in order to reduce noise when shooting in dark light, the overall picture gives us a little fuzzy feeling.

Sony L39h macro proofs

　　　　In macro aspect, both Sony L39h and the previous Sony L36h have a good performance, and the blur of the background is in place. The only difference between them is that they are both shooting outdoors in the evening, but the brightness of Sony L39h is higher.

Sony L39h AR model proofs

　
Sony L39h AR model proofs

　　　　Finally, let’s look at the photo proofs in AR augmented reality mode. Because the dinosaurs or other animations in the picture are constantly moving, the photos taken by everyone must be different. AR animation is very smart to attach to the ground or desktop, and when taking a portrait in AR mode, hats, glasses, etc. will be added to the corresponding positions and will move with the movement of the portrait. However, if we cover a part of the face with our hands, or shoot the side face, these AR elements will not appear on our face.

　　　　Generally speaking, the camera performance of Sony L39h has been greatly improved compared with Sony L36h, but in the process of actual use, we also found some shortcomings. Sony L39h’s imaging speed is a little slower, so it is easy to take a photo because of hand shaking, which will be more obvious when shooting in low light. In addition, it is AR mode, and the effect of shooting through the main camera in low light environment is not very ideal. We hope that Sony can optimize this in the future.

　　　　Next, let’s look at the multimedia performance of L39h. First of all, in terms of video, it is definitely no problem for Xiaolong 800 to play 1080p video, but some formats that Sony comes with cannot be played, and we need to play them through soft decoding of third-party players.

Sound effects can also be turned on in the

　　　　Sony L39h, like Sony L36h and Sony L36H we evaluated before, plays mpg with the help of a third-party player. But overall, the mobile phone plays 1080p video quite smoothly, which also provides a solid hardware foundation for Xiaolong 800. Sony L39h’s video player can also set sound effects to bring a better viewing experience.

　
Various visual effects in the audio player can be set.

　
Only when playing music can it be fixed in the unlocking interface.

　　　　In terms of audio, Sony L39h can play the audio files in m4a, ogg, wav and mp3 formats we tested, but the ape format can only be played with the help of a third-party player. The music player is not much different from the recently upgraded Sony L36h, and just like the Sony L36h, the music player can only be displayed on the unlocking interface when playing music, which means that we can’t directly access the music player from the unlocking interface at ordinary times, but need to unlock it first and then click to enter, which is somewhat inconvenient.

　
Sony L39h Fast Web Browsing Experience

Playing online web videos is quite smooth.

　　　　Perhaps because it is not the final retail version, the application of Sony L39h we evaluated is not very complete. Just for exampleWhen we want to test the online experience, we find that there is no preset in the mobile phone, so we will test it in Sony Select.Sony L39h’s performance in loading web pages, zooming and playing videos is very smooth, which makes it difficult for us to pick out any shortcomings. With enough hardware in place to support it, Sony L39h’s performance is taken for granted.

　　　　Hardware configuration is not the biggest publicity highlight of L39h this time, but in any case, for most users, hardware is always one of the first factors to consider when choosing a product. Sony L39h is equipped with a 1080p display screen, and has chosen the top Opteron 800 processor in Qualcomm at 2.2GHz, supplemented by 2GB RAM and 16GB body storage space, of which the space available for users has reached 11GB. Following the first release of this world’s earliest release, Sony L39h is also the second intelligence equipped with the Opteron 800 processor in Sony products.

Sony L39h with Opteron 800 processor

　　　　Xiaolong 800 processor is equipped with brand-new quad-core Krait 400 CPU, Adreno 330 GPU, Hexagon V5 DSP and the latest 4G LTE Cat 4 modem. Based on Snapdragon S4 Pro processor, the performance is improved by up to 75%, and the process technology is further upgraded to 28 nm HPm technology node. In the multimedia field, Opteron 800 series processors can shoot, play and display UltraHD video.

　　　　In addition to the advantages of performance and speed, Xiaolong 800 processor also has excellent battery life. You can run multiple applications at the same time, surf the Internet quickly, and play videos smoothly, which are all intuitively reflected in our previous evaluation. In addition, the Snapdragon 800 series MSM8274 quad-core processor with 2.2GHz frequency adopted by Sony L39h is an asynchronous processor, and each core supplies power independently. The battery power will be accurately allocated according to the user’s use needs, thus achieving the effect of saving electricity. In addition, with the STAMINA power-saving mode in Sony L39h, the worry-free use of the whole day under normal intensity is not a problem.

The graphics performance of Adreno 330 is 50% higher than that of Adreno 320 (picture from Sony)

　　　　On the GPU side, the graphics performance of the new generation Adreno 330 is 50% higher than that of the previous generation Adreno 320, which allows users to enjoy the freshest 3D games with the best visual effects. The extremely fast performance of web browsing also comes from the performance improvement of Adreno 330.

AnTuTu’s total score is 30444.

　
Rank/comparison in AnTuTu Sony L36h

　　　　AnTuTu Runfen recently released the latest version of V4.0, in addition to the previous four test items of CPU, RAM, GPU and IO, this time it also added the user experience rating item. AnTuTu said that "in the traditional test, the performance limit of hardware will be emphasized, but the highest score of the test can not fully reflect the operating efficiency of the system", and AnTuTu thought that "multitasking ability is a very important indicator. The processing efficiency of multi-core and multi-task will directly affect the fluency of the whole system. " Therefore, AnTuTu V4.0 adds MultiTask Multithread Performance Test, and quantifies the optimization degree of UI/ROM through Dalvik. At the same time, AnTuTu V4.0 also provides 3D performance test in ES 3.0 environment, so the AnTuTu running score in this version is not comparable to that in the previous evaluation, and we can only compare it through the popular model rankings given by AnTuTu for the time being. Obviously, Sony L39h, which runs at 30444, does have the superiority of the flagship model. Compared with Sony L36h, the score is improved obviously.

Sony L39h has made a breakthrough, but there is also room for improvement.

Summary:

　　　　As a flagship product, Sony L39h is very attractive in hardware configuration and appearance. The strong performance of Xiaolong 800 and the integrated application of camera technology make this product have its own unique personality. At the same time, considering that this is the first product under the concept of One Sony, Sony L39h has also become a Sony flagship model with unique significance.

　　　　The device’s HTML5 performance is tested by a picture full of fish in the webpage, in which the number of fish can be set. During the test, the fish are swimming constantly. In the case of the same number of fish in different devices, the faster the swimming speed, the stronger the HTML5 performance, and the corresponding fps value will be given in the page. Similarly, the higher the fps value, the better.

When 10 fish, the Fishbowl test result is 60fps.

With 50 fish, the FishIE Tank test result is 51fps.

　　　　HTML5 is the next major revision of html, and it is still in the development stage. Its main benefit is to strengthen the performance of Web pages and provide better search engine optimization. The Web APP developed based on HTML5 has shorter startup time and faster networking speed, especially for mobile users, which has better picture speed and more exquisite web animation effect.

When Sony CEO Kazuo Hirai took office, we first heard the strategy of "One Sony". This is not the first time for Sony to integrate the technology of other product lines into mobile phones, just like the Walkman series and Cyber-Shot series that we once amazed. This time, Sony once again applied its camera technology to smart phones, and Sony Xperia Z1 L39h became the first product under the concept of One Sony.

　　General situation and characteristics of typhoon Poseidon

　　The 10th typhoon "Poseidon" this year (English name: Haishen；; Name source: China; Name meaning: the mythical god of the sea) was formed in the northwest Pacific Ocean on the night of September 1st, strengthened to a super typhoon level on the 4th, landed on the south coast of South Korea on the morning of the 7th (typhoon level, level 13, 40m/s), moved into helong city, Jilin Province, China in the early morning of the 8th (tropical storm level, level 8, 20m/s), and stopped numbering at 8 o’clock in Dunhua City, Jilin Province.

　　Typhoon Poseidon has the following characteristics:

　　Strong strength and stable path. At its strongest, Poseidon was a super typhoon, its maximum intensity reached 60m/s (level 17), and its intensity exceeded that of No.9 typhoon "Mesak" (at its strongest, it was 52m/s, level 16), making it the strongest typhoon in the northwest Pacific this year. After the formation of Poseidon, its northward path is similar to that of Typhoon No.9, and its landing point in South Korea and its entry into Jilin Province in China are very similar to that of Poseidon.

　　Life history is long, but it is only 5 hours in China. "Poseidon" came into being at 20: 00 on September 1st and stopped numbering in Jilin Province of China at 8: 00 on the 8th, with a life history of 156 hours, but its life history in China was only 5 hours. It moved into China when its intensity weakened to tropical storm level, and then it quickly weakened and degenerated into an extratropical cyclone.

　　Strong wind and rain, the affected area and "Mesak" overlap. Under the influence of Poseidon, the accumulated rainfall in central and eastern Heilongjiang, Jilin, eastern Liaoning and other places is 50 ~ 150 mm, and the rainfall at Huanhe Port in Hunchun City, Jilin Province is 168 mm, and Suifenhe River in Mudanjiang City, Heilongjiang Province is 152 mm; The rainfall of 14 national meteorological observatories exceeded the extreme value in September, and the daily rainfall of Suifenhe in Heilongjiang exceeded the historical extreme value. The above areas are accompanied by gusts of 8-9, with the maximum wind speed of 27.8m/s (Grade 10) in Dongning, Mudanjiang City, Heilongjiang Province and 24.6m/s (Grade 10) in Fangchuan Village, Hunchun City, Jilin Province. The area affected by wind and rain is highly overlapped with the area affected by Mesak.

　　It is rare in history that three typhoons in succession have affected Northeast China in the past half month.

　　In the past half month (from August 26th to September 8th), Northeast China was continuously affected by Typhoon Bawei No.8, Typhoon Mesak No.9 and Typhoon Poseidon No.10, which was the first time since meteorological records were recorded, and the number of typhoons affecting Northeast China was 1.8 more than that of the previous year (1.2). The common features of the three typhoons are as follows:

　　Life history is long, and there is concentration. Bawei, Mesak and Poseidon were all formed in the northwest Pacific Ocean, with their life histories of more than five days, among which Mesak has the longest life history of 168 hours (see attached table).

　　Strong intensity, all of which are typhoons landing northward. The intensity of the three typhoons increased first, and weakened before landing. At the peak of Bawei, the intensity was strong typhoon level, while Mesak and Poseidon reached super typhoon level. The paths of the three typhoons were stable, all of which landed northward. The landing intensity of Bawei and Poseidon was typhoon level, and that of Mesak was strong typhoon level.

　　After three typhoons moved into northeast China successively, they weakened and stopped compiling. After typhoon Bawei moved into Dandong, Liaoning, it continued to move northward into Jilin and then weakened and stopped editing; "Mesak" and "Poseidon" moved into helong city, Jilin Province, then moved westward into Heilongjiang Province, and gradually degenerated into an extratropical cyclone. Among them, "Mesak" stayed in Northeast China for the longest time, reaching 27 hours.

　　Three typhoons have brought strong wind and rain influence to Northeast China. During the influence of typhoons Bawei, Mesak and Poseidon, the average rainfall in Northeast China was 35 mm, 54 mm and 45 mm respectively. After moving into Northeast China, Bawei was dominated by gusts of 6-7, with local gusts of 8-10. "Mesak" is dominated by gusts of 8-10, with local gusts of 11-12; Poseidon is dominated by gusts of 8-9, with a local level of 10. Among them, "Mesak" has the strongest influence, and the daily rainfall of 49 national stations has exceeded the historical extreme in September. Generally speaking, Mesak is the strongest, Poseidon is the second, and Bawei is the weakest.

　　In the past half a month (from August 26th to September 8th), the average precipitation in Northeast China was 170.1mm, which was three times more than normal, and the highest since 1961. Among them, the precipitation in Heilongjiang Province and Jilin Province is 179.6 mm and 228.3 mm, respectively, which is 3-4 times more than the normal period, the highest in the historical period since 1961, and the precipitation in Liaoning Province is 106.5 mm, more than double the normal period, and the second highest in the historical period since 1961. Up to now, the precipitation in Northeast China (641.0mm) has been 27.4% higher than that in the same period of the previous year (503), which is the second highest in the same period since 1961.

　　Attached Table Statistical Comparative Analysis of Typhoon Bawei, Mesak and Poseidon

　

　　Future Typhoon Trends and Suggestions for Attention

　　It is expected that from September 10th to 15th, sunny weather will prevail in most parts of Northeast China, which is beneficial to agricultural production. In addition, it is estimated that there will be 3 ~ 4 typhoons in the South China Sea and the Pacific Northwest in the middle and late September, of which 1 ~ 2 may bring heavy wind and rain to the South China Sea. In autumn, the path and intensity of typhoons are changeable, and super typhoons are prone to occur. Therefore, the public should pay attention to the typhoon prevention work in time. The wind and rain brought by typhoon have a great impact, so it is necessary to guard against the adverse effects of typhoon wind and rain on agricultural production, fishery and coastal aquaculture, and the secondary disasters that may be caused by urban and rural waterlogging, flash floods, landslides and mudslides.

　　(Editor: Zhang Lin)

　　At the beginning of last month, Liu Fang’s autobiographical youth inspirational novel Pomegranate Qingqing, which was conceived and written in three years, was published.

　　This 170,000-word novel, with the western rural education in the early 1990s as the background, depicts the ideals, work, love and friendship of a group of young teachers engaged in rural education. Among them, there are not only daily stories of Liu Fang and her students, but also Liu Fang’s experience in rural education.

　　"Someone asked me what novel I wrote when my eyes were out of sight, and who read it. I firmly say, write to yourself, to the discerning, to the blind, to those who have gone through youth and have dreams, to see a lost youth and to see a bright world in the eyes of the blind. " Liu Fang wrote this in the preface to Pomegranate Green. She hopes that this book can bring more teachers’ college students and future teachers touch and think, and let more people pay attention to rural education.

　　Not long ago, our reporter walked into Liu Fang’s new home in Dijing Jiayuan Community, Baiyun District. The sunshine from the balcony makes the clean and tidy room particularly bright. Liu Fang is wearing a long cotton dress embroidered with white flowers and a black belt with a golden metal chain. Her long hair is tied in a low ponytail behind her head, and she walks slowly from the room with a smile on her face, which is gentle and beautiful.

　　She warmly greeted us to sit down in Mandarin, which had not changed her accent. Although her eyes were invisible, she was very energetic. During the interview, her humorous and joking words made us laugh again and again.

　　★ Character file

　　Liu Fang, born in 1970, was born in Hubei. At the age of 5, she and her mother came to Baiyun District with her father to support the construction of the third line in Guiyang. He used to be a first-class Chinese teacher in Baiyun No.3 Middle School in Guiyang, and now he is a psychological counseling teacher in this school. Director of China Disabled Persons’ Federation Blind Literature Association, member of Guizhou Disabled Persons’ Federation.

　　Rooted in rural education for 21 years, he began to lose his sight gradually due to retinitis pigmentosa in 1997, but he still insisted on cultivating the three-foot platform. Won the title of the second "Moral Model of Dedicated Service in Guiyang" and "Good People Around Guiyang" in 2010.

　　★ Dialogue with Liu Fang

　　Reporter: Although you have lost your eyesight, you are so optimistic, humorous, cheerful and strong. What is the biggest pain you face?

　　Liu Fang: Actually, I am not optimistic myself, but I am optimistic and strong for others. I just found out that I had a great psychological impact when I was sick, and I couldn’t sleep at night. It was very painful to think about what parents, children and husbands should do if they were really blind in the future.

　　When I encounter specific difficulties, I will also be very painful. For example, other teachers use pens to correct papers and exercise books quickly, but I have to get close to see them clearly. I feel that such a simple thing can be so laborious; When I accidentally fell into the ditch while walking, I would feel so sad.

　　When my eyesight is declining and my son is growing up, I find that other pains are not pains, and the most painful thing is not to see what the child looks like. Because the most selfless love in the world is maternal love, how can you show maternal love when children can’t see it? After my son was six or seven years old, I didn’t know what he looked like. I heard that he was handsome and heavy-eyed, but I couldn’t see him.

　　Everyone has their own ideals, but I can’t see, and I can’t do many things I want to do. I still feel very sorry.

　　Reporter: You wrote Pomegranate Green to appeal to the society to pay attention to rural education and rural students. What do you think rural education needs now, and what should society and individuals do?

　　Liu Fang: I have been engaged in education in rural areas for 21 years, and I really feel a lot. At present, the unbalanced development of education is most prominent in rural areas, unlike the schools in the city, which are very balanced in terms of teachers, hardware and equipment.

　　I think rural education needs teachers first. At present, many normal college students have no firm belief in teaching in the countryside. If every normal student is unwilling to go to the countryside, how can the teachers in the countryside be balanced?

　　Secondly, public opinion should have more positive publicity on rural education. Nowadays, we always promote good famous schools and famous teachers, and few people pay attention to why we can’t build a good school in the countryside and lead famous teachers to the countryside. Instead, the countryside has trained a good teacher and sent it to the city, so public opinion has neglected the propaganda of rural education.

　　Third, rural students need to be concerned. Now, in the class where I am the deputy head teacher, 26 of the 44 children are left-behind children, and 30 of the 50 children in a class in the school are single-parent families. Who will supervise and care about their mental health after returning home? Many children go to Internet cafes and are swallowed up by the demons of many black Internet cafes in society.

　　The turning point of life from "white" to "black"

　　When she was in Guiyang Teachers College, Liu Fang was a little night blind, but she didn’t pay much attention. In 1993, at the age of 23, she was assigned to Baiyun No.3 Middle School (then known as Maijia Middle School) as a Chinese teacher and a class teacher. She was absorbed in her work and didn’t take night blindness seriously.

　　However, night blindness is getting heavier and heavier, and ripples begin to appear in front of your eyes during the day.

　　One day in August 1997, she came to the provincial doctor. "You have retinitis pigmentosa. This is a difficult medical problem in the world. There is no medicine and surgery to cure it. In the future, you will slowly lose sight and become blind. " The doctor’s conclusion, like a bolt from the blue hit Liu Fang on the head, she was stunned and her legs and feet were weak …

　　After returning home, Liu Fang did not tell her family about her illness. "Some pains will be magnified when they are spoken, which will make more people suffer together." She works, does housework and takes care of the children as usual, but with the aggravation of eye diseases, she will get caught on the edge of the bowl and the table when she is picking vegetables, even if she is equipped with myopia glasses.

　　In 1999, Liu Fang’s invisibility spread from night to day. She wanted to see the most beautiful scenery before she went completely blind, and went to the World Horticultural Exposition being held in Kunming alone. Up to now, she still remembers the beautiful scenery that made her "amazing".

　　In 2000, the family knew about Liu Fang’s illness. In order not to let her family worry too much, she tried to make herself stronger.

　　In 2006, Liu Fang got a disability certificate. But she thinks that although her eyes are disabled, she can still work and take care of herself. "I am not invisible at once, and many living habits are gradually formed." She walks freely at home now, washing clothes, cleaning and bathing dogs by herself. She is not blind at all.

　　Don’t give up the "three-foot podium dream"

　　"My primary school teacher taught me love, my junior high school teacher taught me rigorous scholarship and strict requirements, my senior high school Chinese teacher taught me to read, love books and revel in teaching, and my college literature introduction teacher made me understand that I should constantly cultivate myself." Liu Fang said that when I first joined the work, my goal was to "be a good teacher like my favorite teacher".

　　Therefore, she never gave up the "three-foot podium dream".

　　In September 2001, after reading Jin Yong’s the legendary swordsman, Liu Fang could hardly see clearly. She began to listen to books on MP3 and radio, and installed software for the blind on the computer to read books. In a year, she "read" more than 20 books.

　　Before, Liu Fang memorized all the key points and difficulties in the key articles of Chinese textbooks for junior high school for three years with her remaining eyesight.

　　She explored a set of her own teaching methods, such as composition class. Her composition comments are very rich, and some students write "Miss Liu, I look forward to reading comments" at the back of the composition. Later, it was very difficult to correct the composition, so she took the students’ compositions to the classroom and let them read them first, and then the whole class commented, revised and graded them together …

　　When writing on the blackboard is difficult, she takes advantage of her strong imitation ability to combine the stories and jokes she has heard with teaching and tell them to students vividly. Speaking, learning, teasing and singing in cross talk, life, Dan, purity, ugliness in Beijing opera are also skillfully used in teaching by her. There is always laughter in class, and students say, "It’s very happy to attend Teacher Liu’s class."

　　During her 21-year teaching career, Liu Fang has been a class teacher for 14 years, and most of her classes are "double-poor classes" and "problem classes". However, in the senior high school entrance examination, these classes often ranked first in the parallel classes of the school, especially in the 2005 senior high school entrance examination, and the top three scores were all in the classes she brought.

　　Transform into a "spiritual mentor"

　　In June, 2008, the last senior high school entrance examination for students led by Liu Fang ended. Since the beginning of the new semester, she has stopped taking classes and teaching Chinese, but has transformed into a psychological counseling teacher in the school.

　　"I can’t see with my eyes, and I can’t change my exercise books, compositions and test papers. The new Chinese textbooks have changed and become more numerous. If I continue to teach, I will teach a language that is lacking." Although it was painful to give up her beloved Chinese teaching, with the encouragement of school leaders and colleagues and the trust of students, Liu Fang chose to transform.

　　"Some people don’t need you to help them solve their problems. They just want to find a psychological spillway." To this end, Liu Fang had the idea of establishing a "growth record bag" for students. The students designed the cover of the file bag themselves and put their hearts in it. "Just put the thoughts and secrets in it and let it go."

　　Nowadays, in Liu Fang’s psychological counseling room, rows of "growth record bags" with different covers are neatly placed. Some students took them away after graduation, and some still stayed in the psychological counseling room. There have been hundreds of them in recent years.

　　"Some children came to me with psychological problems. After giving them counseling, the teacher told me that the child was much better, and I was particularly fulfilled. This is my happiest thing." Every day, many students come to Liu Fang’s psychological counseling room to chat and talk with her.

　　Every semester, Liu Fang will attend classes in 25 classes in the whole school at least twice, give psychological counseling to students on common problems, give some lectures irregularly, and occasionally be invited by other teachers to be a guest teacher of composition. Every week, she will go to the moral lecture hall of the rural children’s palace to tell students moral stories.

　　Support the blue sky of students with love

　　"Liu Ma, how are you recently? You should take care of yourself! " Hu Xin often calls to care about Liu Fang, and sometimes buys a lot of fruit to visit her at school.

　　He is a student of Liu Fang’s class of 2003, but he dropped out of school in the second day of junior high school to work. "Teacher Liu is very kind to us. After I dropped out of school, she always advised me to continue studying. Now I regret giving up my studies, but I am very grateful to Teacher Liu for her love for me." Now 27-year-old Hu Xin drives an excavator in Baiyun District, and often helps Liu Ma. Liu Fang wants to refuse, so he says, "Teacher Liu, I am your son, and we are all your sons. It is right for her to help her."

　　"Children will encounter troubles when they grow up, especially left-behind children, children of floating population, children from single-parent families, and students with learning difficulties. Using’ love’ can help them and give them strength and courage." As long as students are found to have difficulties, Liu Fang will help them, donate clothes and school supplies, and help them pay tuition and clothing expenses.

　　Yuan Fengmei unfortunately became an orphan in the third grade. Liu Fang approached her, comforted her, supported her and gave her family warmth. A few years later, she was admitted to Beijing Normal University and chose to be a teacher. Now she often comes to see "Liu Ma" as a teacher in Huaxi Tsinghua Middle School. "Last year, I had surgery and she stayed with me for one night. In the morning, she quietly put 300 yuan under my pillow and wrote’ My daughter gave money to my mother’." Liu Fang said.

　　Today, Liu Fang is still as popular as ever in Baiyun No.3 Middle School. Before class, the students will take the initiative to pick her up to the classroom. If she appears in class in advance, the students will scream with surprise.

　　Simple life and devoted writing

　　Every day, after getting up and eating breakfast, Liu Fang went downstairs and went to school with her colleagues who came to pick her up for work. After school in the afternoon, she was sent downstairs by her colleagues. After having a rest after dinner, she will exercise on the treadmill on the balcony for an hour, take a hot bath, sit quietly on the floating window of the bedroom and start writing novels …

　　This is Liu Fang’s life now, simple but full.

　　"I like writing. In the past, I mainly wrote prose and poetry. Later, I listened to more novels and began to write novels myself." Liu Fang said that her second autobiographical novel Ten Years of Flowers has written 50,000 words. She arranged chapters according to the flower language. The first chapter "Roses Bloom" wrote about the time of love, the second chapter "Lilies Bloom" wrote about newly married life, the third chapter "Sunflowers Bloom" wrote about the birth of children, and then there was "Jasmine Bloom" …

　　She said that she should write down her marriage, family and love in the ten years that she could not see from sight.

　　★ She in their eyes

　　Zhu Weiran (son of Liu Fang): In my heart, my mother is both strong and fragile. I want to be my mother’s "little crutch" all my life.

　　Ye Zhiya (Vice President of Baiyun No.3 Middle School): Liu Fang is an excellent teacher with a strong Chinese foundation. Although she can’t see with her eyes, she still insists on attending classes, which is amazing and admirable. She regards the school as her home, and she is also very enthusiastic about her colleagues. She can remind me of something difficult to say in a kind way, and she is a very wise person. She cares about her students very much, and her classmates like her very much, calling her "Liu Fang’s mother".

　　Zhou Libo (Liu Fang’s student): "Liu Fang’s mother" is a very kind and strong person. She is very kind to every student. She can find the bright spots in us. She teaches Chinese best. She moves us with her heart and influences us with love, which brings us a lot of fun and warmth. She is brave in the face of life and full of positive energy, which deeply affects us. Thanks to fate, I met such a good teacher. Besides my mother, she is the person I admire most.

　　Mao Yanhong (colleague of Liu Fang): Liu Fang is very thoughtful in teaching. She often gives us guidance in teaching methods and treatment of students. Her composition class is very distinctive. It’s really a pity that she can’t teach Chinese now. She has an open mind and a good attitude. She will lend a helping hand whenever her colleagues need help. She is charitable and enthusiastic about public welfare, and she is a person who takes pleasure in helping others.

"At the hospital, the doctor took him away from us soon. I never saw my son again. He died alone like that. We had no chance to say goodbye to him at all. Now there is only his wardrobe and tropical fish …"

The grief and separation described in the father’s intermittent gibberish in the novel Nemesis really and frequently occurred in North America, Europe and other places in the first half of last century.

The source of all tragedies is a virus called poliovirus. Thousands of infants and young children developed fever and inflammation for unknown reasons at first, and then suddenly they could not breathe spontaneously, were paralyzed and even died. In the classroom full of children’s voices in the past, several seats are vacant every day, some because of isolation, some because of illness, and no one knows which day "you at the same table" will disappear. Historical pictures show that in 1944, a sixth-grade classroom in Milwaukee, the largest city in Wisconsin, USA, was almost empty on the first day of school, and a teacher only taught one student. This scene is embarrassing.

On the other side of the city, the huge cylinder "iron lung" has "eaten" more and more children to help them breathe. Some people walk out of the "iron lung", some people fail to walk out alive, and some people spend the rest of their lives in the "iron lung", with their limbs and bodies in jars, only showing their heads to eat, drink and breathe …

According to records, on June 17th, 1916, new york officially announced the existence of epidemic polio infection. That year, the first polio epidemic broke out in new york, with more than 9,000 cases and 2,343 deaths. The polio epidemic in 1952 was by far the worst, with 57,628 cases reported in the United States alone.

Searching for "patient zero" thousands of years ago.

Who was the first "patient zero" infected with polio virus?

The most famous origin comes from the lithographs in ancient Egypt. A lithograph of the 18th dynasty in ancient Egypt (1403 -1365 BC) depicts a person with muscular atrophy in his right leg, which is regarded as the earliest verifiable document reflecting the pathological state of polio.

There are also manifestations of clinical manifestations of poliomyelitis in TCM books. The earliest record is found in Huangdi Neijing, such as Su Wen Wei Lun, which says, "The five internal organs are hot, which can make people sick and flaccid, and the cover is hot inside and flaccid outside."

People know that the existence of poliovirus is only a short hundred years, but poliovirus has accompanied the evolution of human society like a ghost. The age is so long that the pursuit of polio virus zero infection is meaningless.

It can’t be traced back to the first "intruder" in the whole human society, but in some parts of human society, either because of the fear brought by the unknown, it is necessary to find an outlet to vent, or because of unspeakable political purposes, people will offend each other and even fight for who is the "patient zero" who brought it.

Gao Xi, a professor of history at Fudan University, pointed out in a speech that in the dark European Middle Ages, the scale, duration, coverage, number of deaths and variety of diseases that ravaged the European continent were unprecedented. Infectious diseases, including typhoid fever, smallpox, polio and scarlet fever, spread from one country to another and soon spread in Europe.

Countries go to war and blame each other for this. Among the people, rumors spread everywhere. Witches, Jews and children … Any group that is considered to be different may cause public anger at any time because of a rumor and be pushed into the painful abyss of publicly offending.

"At that time, a more common and excusable statement was that Columbus and his companions brought diseases from the New World to Europe and then spread them all over the world." Gao Wei said.

Ignorance leads to rumors and conviction. The haze of the virus enveloped the European continent at that time, and at the same time, human ignorance made the disaster spread like a virus.

Draw a circle and search for the cause of disease for a hundred years.

At first, people couldn’t relate the figurative and mechanized symptoms of sudden muscle paralysis and limb paralysis to a tiny microorganism, which is why polio has another name: polio.

At one time, polio was considered to be congenital and acquired. There was a secular view that children with polio had problems during embryo gestation, and even it was attributed to ghosts and gods. As a result, generations of polio patients had argued about their rights to get married and have children as adults for nearly half a century.

Back in the 20th century, before the Russian pathologist ivanovski discovered the virus, people knew nothing about this microorganism that could not be seen through the optical microscope. At that time, the disease was called: tooth paralysis, infantile spinal paralysis, primary paralysis of children, degenerative paralysis, anterior horn myelitis, early morning paralysis, etc., and it had no "half a cent" relationship with the virus.

In 1789, a British doctor named Michael Underwood made a clinical description of polio, which he called "weakness of lower limbs".

In 1840, Jacob von Heine, a German orthopedic surgeon, first separated the paralysis caused by polio from other forms of paralysis, calling it polio.

In 1887, Karl Oskar Medin, a Swedish scholar, went out to study individuals and regarded them as epidemics. He recorded an epidemic situation in Stockholm from an epidemiological point of view, and reported the epidemiological characteristics and nervous system complications of polio for the first time.

It was not until 1908, 10 years after the concept of Virus was accepted, that Austrian-born doctors Karl·Landsteiner and Erwin·Popper obtained samples from the central nervous system tissues of patients after death, and then isolated the virus by inoculating monkeys, finally associating paralysis and paralysis with the virus, and drew a closed-loop "circle" in finding the cause.

However, up to now, the closed-loop "circle" of polio caused by virus still can’t erase the prejudice brought by this terrible disease, especially the mutilation it brings is clearly visible, which will make people wonder whether it may be inherited in future generations or associated with "bad luck" regardless of scientific objectivity.

Together, NATO and Warsaw Pact are both healthy covenants.

In the summer of 1921, a cluster of small particles of poliovirus with a size of only 20 nanometers and a icosahedron swam in the water near Campobello Island on the Atlantic Ocean. Small particles drift with the tide, and their surrounding environment is as leisurely and quiet as the earth in ancient times.

A 38-year-old man dived into the water to enjoy the beauty of nature. A small wave came, and the small particles trapped by the sea water entered the man’s mouth and nose.

In just one day, the virus reached the man’s local lymphoid tissue, such as tonsils and other places to multiply and grow; Then the virus further invaded the blood stream, and on the third day, it reached various non-nerve tissues, such as heart, kidney, liver and pancreas, and propagated. The antibodies in the man’s body didn’t have time to stop this powerful offensive of the virus, and watched the virus break through the "blood-brain barrier" and go straight to the central nervous system.

After this trip, the man began to have incontinence, fever and facial paralysis. The paralyzed part began to spread from the hip, and gradually his legs were completely paralyzed, and then his waist … He was franklin roosevelt, who was later elected president of the United States. He was paralyzed for life from the waist down because of polio virus.

His infection and illness brought panic about this virus in the United States in the short term, but in the long run it sounded the "assembly number" for fighting polio virus.

With the emergence of vaccinia to contain smallpox, vaccines have become the "killer" for human beings to deal with viruses. Vaccine makers start with real viruses and try to eliminate their toxicity, so as to produce vaccines.

At the American Public Health Association conference in 1935, two groups of researchers reported their experiments on polio vaccine. In the first group of about 10 thousand children vaccinated, five died of polio and ten were paralyzed. There was no control group in this group of experiments, but John Ke Ermo, who led the experiment, said that the infection rate would be higher without vaccination. Such speculation without factual data made the scene in an uproar.

The second group is Maurice Brodie of new york University. One of the 7500 people vaccinated with the vaccine he developed was infected with polio; One of the 900 people vaccinated in the control group was infected with polio. Although the data is statistically significant, when the audience learned that the infection in the vaccinated population was caused by the vaccine, they all condemned Brody’s research for making healthy people suffer from polio.

Shortly after the report, Brody lost his position at new york University and was found to have committed suicide at home.

The research of vaccine is tortuous, but the scientific spirit and unremitting efforts will inevitably push forward the research and development of vaccine.

On April 12, 1955, the Journal of salk reported an exciting news with a full page: "’s vaccine works! 》（《SALK’S VACCINE WORKS！ 》）

In 1947, jonas salk, an American scholar, set up a three-person research team to jointly overcome the problem of polio. Unlike most researchers who studied live attenuated polio vaccine at that time, salk’s research used inactivated virus as vaccine.

In the United States in 1952, under the threat of epidemic disease, the scale of human trials of vaccine research and development continued to expand. Salk’s vaccine was tested on 1.8 million children, making it the largest medical experiment in human history at that time. Almost the day after the test results were announced, millions of children across the United States were vaccinated against polio.

The debate between "dead" vaccine and "live" vaccine has not stopped because of large-scale vaccination.

Albert Bruce Sabin, who is developing research and development in parallel with salk, insists that only when the live virus enters the human body can the vaccinated people get immunity.

However, Sabin’s "live" vaccine was born a little late. When he developed an attenuated polio vaccine, salk’s vaccine had become the mainstream of the United States, and the government no longer supported his project, so he had to cooperate with other countries.

Disease is not political, and science has no borders. The research and development of attenuated polio vaccine spanned the two political and military camps "North Atlantic Treaty Organization" and "Warsaw Treaty Organization". In 1959, with the support of the Soviet Union, Sabin completed a large-scale clinical trial involving 10 million people, which verified the effectiveness, safety and accessibility of the vaccine.

Ark, leading billions of people away from polio.

In 1950s, poliovirus also occurred from time to time in all parts of China. Even if the weather is sultry, families will let their children stay at home, because there is an invisible and frightening polio virus outside, which will make children disabled after a fever. What is even more frightening is that this virus can be invisible like a "ghost", and healthy people who seem to have no symptoms may also carry it.

At that time, which of the three polio viruses was prevalent in China had not been determined, and the etiology and serology research was almost zero. In 1957, Gu Fangzhou, a scientist from China, led a team to isolate poliovirus from patients’ feces in 12 cities across the east and west, and found that the three types of virus had different characteristics. Through a large number of clinical practice studies, the popular virus types in China were determined, and the laboratory diagnostic criteria of poliovirus were established.

A large number of cases obtained from the investigation made Gu Fangzhou more and more worried. He reported to his superiors that if the incidence of polio was not high, the prevention work could be carried out slowly, but now the incidence is high, and a big outbreak will eventually occur somewhere in a certain year. The outbreak in Berlin in 1947 was a warning, and the pandemics in Nantong in 1955 and Wenzhou in 1956 in China have also sounded the alarm.

In 1959, Gu Fangzhou was ordered to go to the Soviet Union to study the development method and production technology of polio virus vaccine. He found that the existing technology was good, but neither the cost nor the inoculation period was suitable for China at that time. In Gu Fangzhou’s mind, public health should not be "bookish" at all, and any work should be useful and beneficial to the people.

At the international conference on polio vaccine in 1959, Gu Fangzhou, who is good at learning, made it clear that vaccines can be divided into "dead" and "live", and that dead vaccines are safe, but they will not form an immune barrier in human body. Attenuated live vaccines may theoretically restore their virulence, but they can become natural vaccines and form an immune barrier.

With the courage and rational judgment of scientists, Gu Fangzhou made a choice for all the people of China. He wrote to the Ministry of Health at that time, suggesting to choose an attenuated live vaccine that was not proved to be safe and had no mature production process, and personally brought the virus back to China from the Soviet Union.

In December, 1959, the polio live vaccine research collaboration group was established with the approval of the former Ministry of Health, with Gu Fangzhou as the team leader. Vaccine research and development started from scratch, and the team overcame the difficulties of material shortage and harsh environment, and finally got a vaccine sample. With the start of clinical trials of vaccines, it becomes a problem who will take them first.

At the risk of possible paralysis, Gu Fangzhou drank a small bottle of vaccine solution, and the rest of the lab joined the experiment.

The vaccine is harmless to adults, but how safe is it for children? "At that time, my son Xiaodong was just under one year old and qualified." Gu Fangzhou’s oral memory history records: "My own children don’t eat, let others eat, which is not very righteous."

With the development of clinical trials of vaccines, the epidemiological data of 2 million children after taking vaccines show that the epidemic peaks in Shanghai, Tianjin and Qingdao have basically disappeared, and domestic vaccines are safe and effective biological products to prevent polio epidemic.

In Gu Fangzhou’s polio immunization strategy, every child in China cannot be left behind. The oral vaccine rate should reach 95% to form an immune barrier. This means that children who are far away from the Tibetan Plateau, the desert in Xinjiang and the deep mountains in Guizhou must enter the protective barrier without exception. If there is a slight omission, the virus may recur. At that time, there was no cold chain, so it was very difficult for vaccines to circulate effectively in the country in a short period of time. The local method of mixing popsicles with wide-mouthed thermos flask is not very effective.

According to Biography of Gu Fangzhou, Gu Fangzhou, who came home after work, was still thinking about the immunization strategy. His son looked at him. He picked up the candy on the table and shook it in front of his son. His son held out his little hand urgently to make him laugh. Sugar! Gu Fangzhou started the research on vaccine sugar pills. He developed the polio vaccine "Sugar Pill", which made China enter a polio-free era.

In 2000, the World Health Organization announced that polio had been eradicated in the western Pacific, which was closely related to the effective immune barrier formed by polio vaccine in China with a population of more than one billion.

Play around and be alert to the resurgence of sophisticated viruses.

Extinction, doomsday, end …

Since April 8, 1994, when the World Health Organization announced that polio was basically extinct, a large number of reports used similar words to summarize the fate of polio virus.

However, contrary to expectations, polio has never become one of the few infectious diseases that can be eliminated.

In 2000, Cape Verde reported 33 cases of acute polio, including 7 deaths.

In recent years, there have also been cases of infection in Pakistan, and the number of cases has dropped from 306 in 2014 to 54 in 2015, 20 in 2016 and 8 in 2017.

By 2018, less than 30 cases of naturally occurring polio had been reported in Afghanistan and Pakistan.

On March 10th, in Mazar-e-Sharif, the capital of Balkh province in northern Afghanistan, a health department worker vaccinated children against polio. Image source: Xinhuanet

However, according to Science, workers found the virus in a vast area of Pakistan. This disturbing latest discovery shows that it still exists in the environment and is far from disappearing.

Will this virus, which has been dealing with human beings for more than 3000 years, resurface?

As far as the virus itself is concerned, one of the secrets that it has lasted for thousands of years is that more than 90% of the carriers are "secret". These secret infected people have no symptoms, but they provide a secret habitat for the virus to preserve its vitality and wait for the opportunity to revive.

For human beings, rumors can still fuel its "resurgence." For example, rumors that vaccines cause autism are exploited by some religious organizations. Some commentators believe that the resurgence of polio in Nigeria in 2016 after two years of extinction has a lot to do with Boko Haram, an extremist organization in the country. The organization spread rumors among local people, saying that the real purpose of polio vaccine is to sterilize Africans, which led to a large-scale protest in Nigeria, and even several immunization workers were shot dead by extremist organizations.

In the face of ancient viruses, human beings should always remember:

For human tragedies and disputes,

The virus looked on coldly in secret.

For the change and migration of the environment,

The virus "secretly" sees the needle.
