　　Xinhua News Agency, Beijing, January 18th Question: How does Spring Festival travel rush drive in an orderly way? Listen to the traffic police.

　　Xinhua News Agency reporters Ren Qinqin, Lu Chang and Sun Liangquan

　　The scale of cross-regional personnel mobility has obviously increased, with the increase of self-driving passenger trips, the increase of trunk road traffic, and the substantial increase of returning home from work, traveling, visiting relatives and friends … … How can Spring Festival travel rush’s self-driving trips be staggered in an orderly way in 2023? The reporter interviewed the traffic control department and the front-line traffic police to help you.

　　The traffic control departments of many places interviewed by the reporter predict that the road traffic trip in Spring Festival travel rush will show the characteristics of staged high-level operation, short-term concentration before and after the festival, and tidal spatial and temporal distribution.

　　Specifically, before the Spring Festival, the national high-speed travel was relatively scattered. Three days before the start of the holiday, from January 18 to 20, the passenger flow returning home before the holiday was concentrated. Affected by people’s purchasing of new year’s goods, leisure shopping, short-distance visits to relatives and friends, etc., traffic flow concentration and vehicle queues are prone to occur around local goods markets, bustling business districts and passenger stations.

　　Three days after the Spring Festival holiday, from January 25th to 27th, it is estimated that the first wave of returning to the city will be ushered in, with the peak on the 27th and the congestion period from 14: 00 to 19: 00. At that time, the traffic pressure around the expressway and urban expressway and the passenger station will increase. There will be a small return peak on February 6 after the Lantern Festival.

　　Hai Wang, a traffic policeman from Beijing Traffic Management Bureau, said that during the Spring Festival holiday, the toll of passenger cars was reduced on expressways. It is expected that citizens going to Beijing-Tianjin-Hebei, Inner Mongolia, Shanxi, Henan, Shandong and other provinces will also choose to travel by road. The Beijing-Tibet Expressway, Jingcheng Expressway, Beijing-Hong Kong-Macao Expressway, Daguang Expressway and Jingha Expressway are prone to short-term traffic and slow driving, and the traffic flow is large from January 24 to 26.

　　"In 2023, the scale of personnel mobility in Spring Festival travel rush will show a rapid recovery trend, especially in domestic tourist cities, and there will be a peak of people and vehicles." Lin Bingcong, member of the Party Committee of the Traffic Police Detachment of Xiamen Public Security Bureau and a first-class senior police sergeant, analyzed that Xiamen once again became a popular tourist destination in China during the New Year’s Day this year. During the Spring Festival travel rush period, especially during the Spring Festival holiday, Xiamen will continue the trend of high tourists. It is expected that the road traffic around the scenic spot will peak between January 22 and 27; It was not until after the Lantern Festival that it began to return to normal.

　　Zhang Yongjie, squadron leader of Xiadi Squadron of Traffic Police Brigade of Jishan County Public Security Bureau, said that the rallies and temple fairs during the Lantern Festival have increased the pressure on urban areas and rural roads in major counties and townships. One week before the end of Spring Festival travel rush, colleges and universities started classes one after another, and the traffic flow of students returning to school and going out to work was superimposed, and the traffic flow of urban expressway sections, urban areas, county and city passenger stations and surrounding roads increased.

　　What should I pay attention to when traveling by car? Lin Bingcong believes that before traveling, it is necessary to obtain the epidemic situation of the destination, the weather conditions and traffic flow at the passing place in time, and pay attention to the distribution of expressway service areas along the way, the setting of charging piles, meteorological and road conditions information; Conduct a comprehensive inspection of the vehicle to ensure that the vehicle chassis, tires, braking system, lights and other key components are in good condition, tripods, flash sticks, fire extinguishers and other safety facilities are complete, and refuse to take the vehicle "sick" on the road; It is necessary to face up to the fact that driving skills have been unfamiliar since the epidemic, do a good job of physical and psychological recovery before going out, and advocate suspending travel before eliminating the risk of infection or when symptoms such as fever appear.

　　Zhang Yongjie reminded that the number of minibuses, road passenger transport and tourist passenger transport in Spring Festival travel rush increased this year, and the phenomenon of mixed passenger and freight traffic was prominent. Some drivers turned from long-term low-load operation to normal state, which increased the risk of traffic accidents because of their inadaptability to vehicles and roads, so they needed to pay special attention to driving safety.

　　In response to the actual travel needs of the masses, local traffic control departments will rely on media such as traffic radio, television, Internet, Weibo, WeChat, etc. to timely announce traffic flow prediction and diversion and bypass plans, so as to ensure safe and smooth roads during Spring Festival travel rush and create a safe, smooth and harmonious travel environment for the masses to celebrate the Spring Festival.

On the morning of New Year’s Day, many people were still asleep after the reunion on New Year’s Eve. Zhang Chu Town, secretary of the Party branch of Ximei Village, Gurao Town, Chaoyang District, Shantou City, and the village-level river chief of Gurao River, got up early and drove from home to patrol the river next to Gurao River, a secondary tributary of Lianjiang River, as usual. "I’m worried that the firecrackers and scraps of paper set off by the villagers will fly into the river, so I must come and have a look."

During the Spring Festival, Zhang Chu Town is far more than the only one that is worried about the length of the river governing the water pipe.

At the end of last year, the provincial pollution prevention and control tough battle headquarters issued the first order, calling for a special campaign to comprehensively attack the inferior V national examination sections, resolutely prevent the addition of inferior V national examination sections, and basically eliminate inferior V national examination sections in 2020. Including Lianjiang and other inferior V water bodies. At the same time, there are more than 38,000 five-level rivers and lakes in our province, and the total number of them is more than 150,000, plus the river length and river patrol set up by villagers’ groups. Go deep into the main tributaries, realize the full coverage of rivers and lakes in the province, earnestly perform their duties, drive all walks of life to work together, and implement water control at the ends of twigs, which has become a powerful starting point for Guangdong to fight hard for clear water.

The director of Raoxi River in Lianjiang Valley and the project personnel stick to their posts.

In the mobile phone of Zhang Chu Town, the reporter saw the information such as the time, place and walking track of his river patrol in Guraoxi on the platform of "Guangdong Wisdom River Chief". "I basically go for a walk every day." As the river chief at the grass-roots level, Zhang Chu Town admits that it has become his working habit to "patrol the river when he has nothing to do" in recent years, and the Spring Festival is no exception.

Guraoxi is the main river for flood discharge and drainage in Gurao Town, and it is also a secondary tributary with heavy pollution in Chaoyang section of Shantou in Lianjiang River Basin, which flows into the main stream of Lianjiang River through Beigang River. In July last year, illegal buildings on both sides of Guraoxi River that had occupied rivers and polluted directly for decades were demolished one after another, and now Guraoxi River has become much wider and cleaner. However, the work of pipe network construction and village appearance cleaning still needs to be continuously promoted.

"In the past Spring Festival, the domestic garbage in the village will increase a lot." Zhang Chu Town told reporters that in addition to patrolling the river, he also focused on the sanitation work in the village: the village committee contracted the daily cleaning work to the cleaning staff at a monthly rate of 13,000 yuan, and then they hired their own people to do it together. Now this work has been brought into normal management.

Not only is the river chief busy, but the construction unit of the second phase project of Gurao Sewage Treatment Plant also has employees sticking to their posts. Huang Chuwen, a member of the Party Committee of Gurao Town, told the reporter that on the first day of the New Year’s Day, there were still 11 employees at the construction site of the second phase of Gurao Sewage Treatment Plant who gave up the Spring Festival holiday and fought for the front line. Most of them come from Hunan, Sichuan and other places, and stick to their posts only to ensure the steady progress of infrastructure equipment installation and pipe network laying in the factory.

Village-level river chiefs in Xiaodongjiang Town, Maoming patrol the river for 3 hours every day.

Not only Lianjiang, but also Xiaodongjiang, a tributary of Jianjiang, is also tackling the problem of eliminating inferior V water bodies.

"According to the goal set by the province, efforts should be made to improve the Xiaodongjiang River from the inferior V water body to the V water body this year." Xie Kairong, who is patrolling the river near Xiaodongjiang, said. Xie Kairong is the party secretary and township-level river chief of Aotou Town, Maonan District, Maoming City. Since the third day of the year, the town and village river chiefs in Aotou Town have been patrolling the river every day. "Patrol the river for about 3 hours every day to see if the river is clean, and also remind children playing by the river to pay attention to safety." Since the fourth day of the Lunar New Year, Xie Kairong has toured the reaches of Meihuajiang, Xiaodongjiang and Helinhe. During the Spring Festival, many rural sages also returned to their hometowns. Xie Kairong took this opportunity to mobilize rural sages to donate money and contribute to water control.

Not only the long river patrol, but also the means of sewage treatment and ecological restoration are applied to the treatment of Xiaodongjiang River. During the Spring Festival, in Pengcun Lake, Maonan District, Maoming City, canna and other plants are flourishing in an artificial wetland covering an area of more than 20 mu. The construction party, Huang Gong of Shenzhen Biyuan Environmental Protection Technology Co., Ltd., is starting the grid machine to separate the garbage flowing into the wetland water. Huang Gong said that he was on duty in the wetland during the Spring Festival. "We are stepping up the acceptance of this project and strive to complete the acceptance and handover in March this year, which will have an early effect."

The filtered water from Pengcun Lake constructed wetland finally flows into Xiaodongjiang River, effectively improving the water quality of Shi Bi section of Xiaodongjiang River. Next, around Pengcun Lake, Maoming will also build 57 village-level sewage treatment stations to further reduce the sewage discharge in villages and towns.

In Maoming, another national examination section-Jianjiang Jiangkoumen section, Huazhou city in the upper reaches is also stepping up governance. In the high and low drainage channels of the Maoling River in Huazhou, 27 container-sized tanks are neatly stacked into two floors like building blocks, and the tanks are connected by large and small pipes, making it a sewage treatment plant with a treatment capacity of 30,000 tons. On-site personnel Huang Zhenlin and Hu Yu are checking the operation of the equipment. They are also on duty in the factory during the Spring Festival. "We two take turns and are on duty 24 hours a day."

Wu Haoguang, director of the Environmental Protection Bureau of Huazhou City, said that in order to ensure that the cross section of the downstream river mouth reaches the standard, Huazhou City invested nearly 60 million yuan to install and operate this integrated intensive treatment facility beside the high and low drainage channels. The monitoring data show that the main pollutants such as ammonia nitrogen and total phosphorus in the water quality of Jiangkoumen section have dropped significantly since last year. "This year has had a very good start. Now the water quality of Jiangkoumen section has reached Class III or above, and most indicators have reached Class I and Class II or above. Jianjiang water quality is expected to reach the best in recent years."

From 11: 00 to 12: 00 on April 12, gusts in some areas of Beijing reached 9-11, and even reached 14 in mountainous areas. Meteorological stations with wind speeds above 10 are distributed in Haidian, Chaoyang, Fengtai, Tongzhou, Fangshan, Changping, Huairou, Pinggu, Mentougou, Yanqing and Shunyi. Despite the strong winds, farmers in farmland, cooperatives and peach groves in the suburbs of Beijing are still busy.

On the evening of April 11th, some areas in Pinggu were hit by hail weather, which worried the peach farmers. Tangtang runs a cooperative in Pinggu. When the hail came, she took a video with her mobile phone and recited the big peaches at home. Fortunately, the hail didn’t last long. The next morning, Tangtang went to Taolin to check the situation of big peaches and found that many peaches were blown off.

Qu Haiquan, 65, has planted big peaches for decades. In Xiagezhuang Town where he lives, there is only strong wind and no hail. His family has 70 acres of big peaches, most of which are planted in the open air and a few in greenhouses. The peaches in the greenhouse will be harvested soon, while those in the open air will wait until June. Qu Haiquan is full of confidence in the newly introduced detached peaches and nectarines. He said that peaches are not afraid of strong winds, but they are afraid of hail and cold spring. He thinks that the strong wind has little effect on peaches.

Peach blossoms in Pinggu are in full bloom. Will this strong wind affect flower viewing? A peach farmer said that his peaches were not sparse this year. When he checked in the morning, he found that all the flowers were blown off, and other flowers were still on the trees, so the impact of strong winds was limited. Peach blossoms in Pinggu are still tenacious and swaying in the wind.

On the short video platform, some peach farmers took netizens to enjoy flowers through live broadcast. The pink peach blossoms in the picture are swaying in the wind and full of vitality. There are also peach farmers selling agricultural products live in cooperatives or greenhouses.

Yang Yang, the head of Tongzhou Houyuanhua Ecological Picking Garden, has been busy in the garden. The strong wind blew up the quilt on the greenhouse, and the plastic film in some greenhouses was also blown away, and the green leafy vegetables inside swayed with the wind. Yang Yang was busy delivering goods to customers while contacting the insurance company to check the greenhouse situation.

In special weather, farmers are concerned about crops. Zhang Haiying, a big planter in Shexian Town, Tongzhou District, went to inspect the field early and found that the wind was very strong in the field, but the wheat seedlings were not fully jointing and the plants were short, which would not cause lodging. She mentioned that if there is such a strong wind again after mid-May, it may not work. When she was patrolling the field, she also saw a magpie spinning and falling by the strong wind.

　　editorial comment/note

　　With the outline of the national long-term scientific and technological development plan (2006— With the implementation of "2020)", China’s investment in scientific research and discipline construction is increasing, the pace of development is obviously accelerated, the innovation ability is gradually improved, and its international influence is expanding day by day. A series of reports on discipline development research issued by China Association for Science and Technology (2014— 2015) shows that in recent years, China’s discipline construction has achieved a number of important achievements, the overall level has been greatly improved, and many key scientific and technological indicators have entered the forefront of the world. We are changing the world R&D pattern.

　　In the 21st century, the rapid development of the new scientific and technological revolution has promoted the intersection, integration, infiltration, differentiation and development of disciplines, and given birth to new major breakthroughs.

　　In recent years, China’s investment in discipline construction has been increasing, the discipline development environment has been continuously optimized, the discipline team has been growing, the discipline platform construction has been improved, and international cooperation and exchanges have been strengthened, which has effectively promoted the development of discipline construction and scientific research, and the basic disciplines and applied disciplines have also been continuously improved and developed. The innovation bred by interdisciplinary integration is gradually changing the discipline structure.

　　1. Significant achievements in discipline research.

　　Since the 21st century, the number of international scientific papers published by scientists in China has shown an alarming growth rate, which has aroused widespread concern in the international scientific and technological circles, which also reflects the development trend of various disciplines in China.

　　Extended version of the Web of Science Science Index of Thomson Technology Group — — ESI database divides all natural science fields into 22: clinical medicine, chemistry, physics, biology and biochemistry, molecular biology and genetics, neuroscience and behavior, materials science, engineering science, botany and zoology, environmental ecology science, immunology, pharmacology and toxicology, earth science, neurology and psychology, agricultural science, microbiology, space science, computer science and so on.

　　From 2005 — According to the data in 2015, some disciplines in China are already in the leading position in the world and have strong influence in the world. High-quality research achievements in 22 disciplines in China have increased significantly, among which the number of international scientific papers published in chemistry, physics, engineering science, material science and clinical medicine has exceeded 100,000, especially in chemistry, reaching more than 300,000; In addition, the achievements in the fields of biology and biochemistry, earth science and computer science are also very impressive. Among the 22 disciplines, China has the highest number of "articles are cited" in many disciplines, which is 18.63; Followed by molecular biology and genetics, with 11.55.

　　As of 2015, from the ranking of the number of published papers, 17 of the 22 disciplines in China are in the top five in the world, among which, China’s chemistry and materials science ranks first in the world.

　　In addition, the proportion of periodical papers published in the field of system science and system engineering in China increased from 23.5% in 2010 to 32.1% in 2015, making it the leading country in this field in the world.

　　At the same time, China’s frontier subject papers have made great achievements. In October 2015, the Literature and Information Center of Chinese Academy of Sciences and Thomson Reuters, an international professional information service provider, released the report "Research Frontier in 2015", which showed that China had core papers in 82 frontier disciplines, and the number of core papers in 16 frontier disciplines was the first. This shows that China has a strong frontier contribution and ranks among the world’s advanced in some important frontier disciplines.

　　In addition, the report also shows that there are 38 frontier disciplines in China, with 133, 68, 55 and 29 in the United States, Britain, Germany and Japan respectively. The 16 frontier disciplines in China ranked first in the number of core papers are from the fields of chemistry and materials science, physics, mathematics, computer science and engineering, agriculture, botany and zoology, biological science and earth science.

　　Among them, in the field of chemistry and materials science, China’s contribution to frontier disciplines exceeds that of the United States. Among the 19 frontier disciplines in this field, China ranks first in the number of core papers among the 9 frontier disciplines, and the United States has 7.

　　2. The application trend of basic research is obvious.

　　In recent years, the application trend of some basic research in China is obvious. The transformation period of basic research results is shortened, and the boundary between basic research and applied research is increasingly blurred.

　　For example, in the field of mathematics, the numerical solution of developmental partial differential equations has become a rapidly developing discipline in the field of applied mathematics, and it has important applications in aerospace, electromagnetism, petroleum exploration, semi-conductor device simulation, water pollution treatment, ocean and meteorology. The research on numerical simulation methods of these mathematical and physical equations belongs to the frontier research field of science and engineering calculation, and the design, analysis and application of high-order precision numerical algorithms for these problems have always been a challenging topic.

　　From the specific disciplines, basic disciplines such as biology, life science, chemistry and earth science have made remarkable progress in the application of basic research.

　　Take the "973" project with Zhao Guoping, the chief expert of Shanghai Academy of Life Sciences, Chinese Academy of Sciences, as an example. Focusing on the key scientific issues and related technical difficulties such as the design principle, synthesis and assembly, module construction, standardized library building and integration and adaptation mechanism in chassis cells, this project focuses on the artificial heterologous synthesis of terpenoids, and has made some important progress, especially in the important medicinal and edible terpenoids such as rare ginsenoside CK, stevioside and tanshinone precursor rust alcohol. In addition, significant progress has been made in the mining and synthesis technology innovation of component modules.

　　The application of synthetic biology technology in tumor research is just beginning at home and abroad. The "973" project "Basic research of synthetic biological devices in bladder cancer intervention", headed by Professor Cai Zhiming of Shenzhen University, applied synthetic biology technology in tumor treatment research on the basis of system biology. The project discovered some key genes and pathways of bladder cancer, and based on the analysis of relevant gene network information, the quantitative controllable engineering system was used to characterize the commonness of complex events in the occurrence and development of bladder cancer, and many potential compound targets for bladder cancer identification and treatment were excavated.

　　In physics, near-field optical tweezers is a new technology based on near-field optical theory, which can capture and manipulate particles stably. Compared with the traditional far-field optical tweezers based on single beam gradient force, near-field optical tweezers overcome the limitations of optical resolution diffraction limit and thermal effect, and can capture and manipulate nano-sized particles. Optical tweezers are widely used in biology, physics and chemistry because of their unique non-contact and non-destructive characteristics, especially in biology, which has been used to study cells, viruses, bacteria and DNA molecules.

　　In chemistry, with the development of strategic emerging industries in China, new materials have become a hot research direction in recent years. By exploring the properties of different kinds of materials, practical problems encountered in production and life can be solved. Supercapacitor is a new type of energy storage element between traditional capacitor and chemical power supply. It has the advantages of short charging time, long cycle life, good power characteristics, wide temperature range, economy and environmental protection, and has been widely concerned in many fields. The development trend of electrode materials mainly has two directions: compounding materials, using the synergistic effect between different materials, compounding and doping between different materials, in order to obtain electrode materials with excellent performance; Nanometer materials not only have high specific surface area, but also can improve the transmission and diffusion paths of electrons and ions, thus improving the electrode performance.

　　In addition, China has accumulated a lot in some important frontier fields of basic research, and has also bred new breakthroughs in application, such as dark matter, discovery of new particles and survey of the sky in Hanoi, which is expected to deepen human understanding of the universe and then play an important role in human space exploration; In the fields of high temperature superconductivity and topological insulators, quantum memory, quantum regulation, mesoscale science, etc., it is expected to explore and discover new physical and chemical principles and produce application value; In the research fields of synthetic biology and brain science, it is possible to explore the origin of life and innovate scientific thinking methods.

　　3. The growth rate of disciplines related to people’s livelihood.

　　The development of information science and technology is in the ascendant, and it is the leading force of sustained economic growth; The rapid development of life science and biotechnology plays a key role in improving and improving the quality of human life; Energy science and technology continue to heat up, opening up new ways to solve energy problems; The rapid growth of new achievements in the field of environmental protection provides new solutions to environmental problems. Science and technology related to people’s livelihood have been vigorously developed, and the speed of application and transformation of science and technology has been accelerating.

　　Taking Chinese medicine as an example, Chinese medicine is a unique health resource in China and an important national industry, which is of great significance in the overall economic and social development. Historical reasons and the complexity of traditional Chinese medicine itself restrict the varieties of traditional Chinese medicine to become bigger and stronger. The secondary development of traditional Chinese medicine has led the innovative development direction of traditional Chinese medicine industry, promoted the technological upgrading of traditional Chinese medicine industry, played a significant role in ensuring the success of medical reform in China and promoting the development of biomedical industry, and produced significant economic and social benefits.

　　For example, around the great demand of making Chinese patent medicines bigger and stronger, and promoting the transformation of Chinese traditional medicine industry to science, technology, efficiency and economy, the research group of Academician Zhang Boli of Tianjin University of Traditional Chinese Medicine took the lead in putting forward the research strategy of secondary development of Chinese patent medicines. After theoretical innovation, technical breakthrough and popularization and application, five core technical systems, such as accurate clinical positioning of Chinese patent medicines, systematic analysis of pharmacodynamic substances, network pharmacology, process quality optimization and digital whole-process quality control, were established, and a secondary development model of Chinese patent medicines was formed, which effectively promoted the technological upgrading of Chinese traditional medicine industry and enabled Chinese medicines to be upgraded. The project has completed the secondary development of 32 varieties of Chinese patent medicines, and the number of varieties with sales exceeding 100 million yuan has increased from 3 to 12. The project technology has been promoted in many places across the country and applied to nearly 100 Chinese medicine enterprises.

　　4. Interdisciplinary integration breeds innovation.

　　Interdisciplinary integration is the source of innovation. The intersection and integration of disciplines is often the frontier of innovation, which leads to major scientific discoveries and the emergence of emerging disciplines. At present, many disciplines are committed to cultivating the awareness of interdisciplinary integration, exploring effective ways of interdisciplinary integration, stimulating innovation vitality, improving innovation quality and comprehensively enhancing innovation ability.

　　Biomedical interdisciplinary subjects are constantly exploring and deepening in frontier fields. For example, Professor Wang Xiaoying from the Imaging Department of the First Hospital of Peking University, Zhou Diange’s research team from the Department of Orthopaedics of Peking University People’s Hospital and Zhang Jue’s research team from the Peking University Biomedical Interdisciplinary Research Center cooperated closely to innovatively develop a new type of flexible coil, which provided a brand-new idea for the design and imaging of magnetic resonance radio frequency coil and non-invasive perfusion functional imaging of lower limbs.

　　In recent years, China’s frontier interdisciplinary subjects have effectively promoted the system construction, discipline construction and team construction of disciplines in China by exploring the innovation of scientific research and management mechanism, promoting the construction of basic conditions, recruiting and introducing outstanding scientific research talents, and organizing academic exchanges and research project applications.

　　Under the framework of the Frontier Interdisciplinary Research Institute, each research unit, based on its own existing conditions and facing the development of science and technology and the needs of the country and society, organized multidisciplinary research forces to carry out research on frontier issues and tackle key problems in science and technology, won the support of various interdisciplinary research projects, and achieved some important research results.

　　On October 2, 2022, General Secretary of the Supreme Leader wrote back to all geologists of the Sixth Geological Brigade of Shandong Bureau of Geology and Minerals, and raised ardent expectations for them to carry forward their fine traditions and do a good job in mineral exploration, encouraging them to strive to write a new chapter in the "heroic geological team".

　　Take up your bags and go to the world, and walk all over the mountains before you see gold. Our reporter went to Weihai, Shandong Province, and approached the Sixth Geological Brigade, recording the exploration stories of the team members who waded through mountains and rivers, slept in the wind, and overcame difficulties and the extraordinary course of prospecting for the country, and felt the fine tradition of patriotic dedication, pioneering and innovative, and hard struggle … …

　　— — Editor

　　Shixian Li, an 86-year-old former deputy chief engineer of the Sixth Geological Brigade of Shandong Bureau of Geology and Minerals, opened a drawer and took out a People’s Daily dated October 5, 2022. He read it word by word. "I read the reply from the General Secretary again and again, and I was very excited and encouraged … …” Shixian Li said.

　　Since its establishment in 1958, it has completed drilling footage of more than 5 million meters, equivalent to the height of more than 600 Mount Everest. Accumulated proven gold resources are more than 2,810 tons, making it the geological team with the most gold prospecting in China; In 1992, he was awarded the honorary title of "Heroic Geological Team with Outstanding Achievements and Selfless Dedication" by the State Council … … Close the newspaper, Shixian Li talked about the glorious course of Team Six.

　　Searching for gold to serve the country and breaking the traditional prospecting model

　　■ The first super-large altered rock type gold deposit in China has been found.

　　Shandong Jiaodong Zhaoyuan, known as "Jincheng Tianfu", has a local folk song: "The golden mule goes, the mill turns, and all it grinds is Jin Doudou." Legend has it that it’s not easy to get "Jin Doudou", you have to open the mountain gate first. In 1958, a 94-member exploration team advanced to Zhaoyuan and took the first step in searching for gold for the country. This team is the predecessor of the Sixth Team.

　　In 1960, Shixian Li graduated from the Geology Department of Shandong University, and was assigned to the Sixth Team, just in time for the "General Prospecting War". During the day, the team members searched for clues, leveled alleys and dug shallow wells, and at night, they spread hay, paved the floor and made plans. Shixian Li made up his mind: We must dig up several "Jin Doudou" for our country!

　　At the beginning of the construction of the team, the members of the sixth team just circled in the gold-bearing quartz vein type gold mine. "At that time, by foreign experts ‘ The large fault zone only guides ore but does not store it ’ Because of the influence of the conclusion, we regard the great fault zone as a restricted area for prospecting, and have never ‘ Step beyond the line ’ 。” Shixian Li said.

　　Are there any other types of large gold deposits? On the coast of Bohai Sea and Laizhou Bay, there is a small island surrounded by water on three sides — — Sanshan island. Stepping on a foot thick snow and facing the biting cold wind, the six team members went to Sanshan Island; After sampling and testing, it is found that there is a new type of gold mine here — — Altered rock type gold deposit in fracture zone.

　　This is a great discovery! "For this discovery, the members of the six teams fought bravely, and even some members gave their precious lives." Shixian Li said.

　　In 1966, Zhang Yuzhi was appointed as the technical director of Sanshan Island regional census, when he had just undergone major lung surgery. Every morning, he waded through the water island to select points and take samples, and at dusk, he returned with his ore on his back … … The leader of the unit was afraid that his body could not stand it and wanted to transfer him back to the office, but Zhang Yuzhi chose to stick to it: "The country asked us to find gold. How can we find it when people are not in the wild?" At the last moment of his life, he put on hiking shoes and walked around the ward until he never stood up again.

　　On the basis of general survey and exploration, the mining exploration report compiled by Zhang Yuzhi passed the evaluation, and the first super-large altered rock type gold deposit in China was found! "This discovery has broken the traditional prospecting model." Shixian Li said, "Soon, we found a super-large Jiaojia gold mine in the middle of another fault zone; I touched Xincheng Gold Mine, Matang Gold Mine and Dongji Gold Mine. "

　　Finding the mine is only the first step. The team members feel that it is an urgent task to analyze and summarize the theory of new types of gold deposits and guide gold exploration. In 1971, the team set up a comprehensive geological research group, which was headed by Shixian Li. One day in 1976, in a small farmhouse, Shixian Li got together with his team members to discuss … …

　　"If the gold mine is found, you must first name it." Shixian Li said. "There are Carlin-type gold mines and Rand-type gold mines abroad. Why can’t we call them Jiaojia-type?" "You must put ‘ Broken zone ’ Crown, this is the main feature … …”

　　Everyone said a word to me, and finally determined the name of the mine. In 1977, at the Second National Gold Geology Conference, "Jiaojia-style altered rock gold deposit in fracture zone" was officially named and established. In 1985, the project achievement of Team Six, Discovery of Jiaojia New Type Gold Deposit and Its Outstanding Prospecting Effect, won the first National Science and Technology Progress Award.

　　Be brave in pioneering and March towards the depths of the earth.

　　■ "Five Golden Flowers" such as Sizhuang and Jiaojia bloom for the second time.

　　In the history of gold exploration, "five golden flowers" are famous far and near. This "golden flower" is not a woman, but a genuine "golden flower".

　　In 2003, Wang Qihong, the twelfth captain of the Sixth Team, took office. Before leaving, Wang Qihong, who was usually taciturn, uttered a few words: "Thank you to the Party Committee of the Bureau for giving me this burden. If there is a ladder to the sky, I can take this team to reach for the moon!"

　　"malicious words" have been released, but the problem is in front of us! In the past, prospecting was within 500 meters below the surface, but now the surface mines and shallow mines have basically been developed. What should we do next? Looking for minerals deep in the earth, this is the only way out!

　　With the support of the Provincial Bureau of Geology and Mineral Resources, the battle headquarters with Wang Qihong as the chief commander was established, and the technical backbone was selected to form a project team. In the first month of 2005, the sky was full of snow, and the drums of the "Sizhuang Battle" were drumming, and the six teams were ready to go, heading for the underground kilometer. Some people have questioned that it is impossible to form a large mine here because of its "thin ore body, low grade, small scale and deep burial". Wang Qihong insisted: "We must break through!"

　　Jiang Hongli, the technical director of the project, locked himself in the headquarters, repeatedly looked at the drawings, turned over the exploration and mining data and analyzed the deep structural changes. After repeated deliberation, he improved the construction scheme, and made two exploratory drilling holes in the most likely ore-seeing part.

　　A hole, a dozen is 2 months, thousands of meters. The first drill hit the gold as I wished; The second drill saw a good mine, and its grade and thickness were unexpected. In the end, 52 boreholes were drilled, with a penetration of more than 40,000 meters, and the proven resources of Sizhuang Gold Mine were 51.83 tons, with a potential economic value of more than 8 billion yuan. The first "Golden Flower" was born in Sizhuang, which is the first super-large deep gold mine in China.

　　Will there be a miracle in the deep part of Jiaojia in the north of Sizhuang? Wang Qihong decided to try. With the experience of Sizhuang and the technical scheme, Jiaojia’s deep exploration was "pleasantly surprised" at the beginning, but when drilling the fourth hole, something worrying happened: no mine was hit.

　　The headquarters froze up and down … … Wang Qihong called a meeting of technicians to organize discussions, and various technical means of geological and geophysical exploration went into battle. Everyone made a bold guess: this buried "golden flower" may be dumbbell-shaped.

　　Sure enough, when the drilling went to the eighth drill, we finally found the "dumbbell handle" in the depth of 1000 meters. At the moment when the core at the expected mine site was taken up, the young team member Bao Zhongyi rushed forward and excitedly brushed away the dust on the rock: Ming Jin Shanshan shines!

　　The test results made everyone jump for joy: the highest gold grade was 110.04g/ton. During the deep exploration in Jiaojia, the Sixth Team finally discovered 105 tons of gold resources, with a potential economic value of more than 20 billion yuan. Subsequently, Zhu Guo, Li Jia, Sha Ling, Qian Chen and other "three golden flowers" bloomed for the second time … …

　　Pass from generation to generation, follow the footsteps of our predecessors

　　■ Establish four provincial and ministerial innovation platforms and six high-level scientific and technological talent innovation teams.

　　Fan Jiameng, the "three generations of the earth", followed his grandfather and uncle to the mountains when he was a child, fiddling with compasses and waving hammers. Xiao Jiameng often thought, "When can I find treasures?" After graduating from college, Fan Jiameng joined the Sixth Team. Looking forward to it is beautiful, but it is really on the road to finding gold. He played a "retreat" … …

　　In 2012, Fan Jiameng was sent to Xinjiang for exploration. Trekked more than 3,000 kilometers and arrived at Lop Nur Town Transfer Station. "On that day, the temperature was MINUS 20 degrees Celsius, and we were at ‘ Diwozi ’ I stayed up all night. " Fan Jiameng said that that night, he stayed up all night looking at the leaking roof, the uneven ground and the floor covered with debris … …

　　Arriving at the project site the next day, Fan Jiameng stood on the Gobi Desert, listening to the wind, looking at the dust all over the sky, without a trace of green, and several empty iron houses trembled in the wind! Fan Jiameng’s mood is very low: "I want to pick a load!"

　　Once, his mother called him and said sadly, "Why don’t you tell the team to go back to Shandong and go out in the wild?" Unexpectedly, grandpa’s yelling came from the other end of the phone: "Do you think geological exploration is for fun? If you can’t eat this bitterness, don’t come to the sixth team! " Mother didn’t dare to speak any more, but after a few words of comfort, she hung up the phone … …

　　"At the beginning is blunt ‘ Hero Geological Team ’ Come, then retreat is not a joke? " Fan Jiameng calmed down and remembered his grandfather’s words: "Choosing geology means choosing to be with hardship and be at home in the world;" Choosing six teams is choosing responsibility. " Fan Jiameng stayed, and 10 months later they completed the exploration project of Lop Nur.

　　In order to pave the way for young scientific and technological talents to become talents, Team Six has established four provincial and ministerial innovation platforms and six high-level scientific and technological talents innovation teams. In the exploration battle of Shuiwangzhuang mining area, the youth geological project team was established in the team, and Fan Jiameng bravely took the lead and became the person in charge. Aiming at the problem that core sampling in the fractured zone is easy to damage the drill bit, their team invented and introduced innovative technologies such as "bending-proof drilling tool", "drag reduction inner pipe" and "hydraulic cutter".

　　Even with the new technology, the construction period is still urgent. They compare the progress of the project every day, find problems and think about countermeasures. One day, there was a heavy rain, and the office was blacked out, so candles could only be used for lighting; The candlelight jumped, reflecting the faces of several young people. When the statistics of the engineering quantity of the day were completed, it was sunny and sunny, and the stars were all over the sky. Eating instant noodles and looking at the starry sky, Fan Jiameng muttered, "I miss the steaming steamed buns of my mother."

　　After exploration, Shuiwangzhuang mining area has discovered a total of 186 tons of gold resources, which is the largest gold deposit discovered in Zhaoping fault zone so far. Zhaoping fault zone has thus become the third thousand-ton ore-controlling fault zone in China.

　　Go abroad and join in the construction of the "Belt and Road"

　　■ In Team Six, everyone is good.

　　In recent years, the Sixth Team has shouldered the mission entrusted by the state and helped the countries along the Belt and Road to achieve a breakthrough in prospecting. We’re leaving again! Before leaving, Zhang Peng’s wife always felt that she didn’t bring enough things, so she bought him new shoes, socks and water cups early. "I will go to Sudan next week, and it will be half a year before we meet again." Zhang Peng said.

　　In 2012, Zhang Peng followed the team to Tajikistan. The mining area is located in Pamirs, which is nearly 4000 meters above sea level. The first difficulty is to overcome altitude sickness. Oxygen is thin, Zhang Peng is always flustered and short of breath, nosebleeds flow intermittently, and his lips are cracked … …

　　The temperature in the plateau is low. Every October, the mountains are closed by heavy snow, and the draught has become a problem. You can only smash ice cubes and use the stove to make water. Cooking on the plateau, steamed bread is not ripe, bite sticky, eat a steamed bun even for the New Year. "Knock around with a hammer and take a bunch of samples back. The shoes and trousers are worn out and can only be mended by themselves." Zhang Peng recalled.

　　Loneliness is the most unbearable. "In a deserted place, it is a surprise to hear wolves barking!" Zhang Peng said that he was afraid of his family’s worries, and told his wife that his job was like a tour of the mountains and waters, which was a "pulse" for the earth. The wife complained, "Going abroad ‘ Take a pulse ’ , why so long? " Zhang Peng said, "This is a national event, and we must do our best." Finally, through core comparison, the team explored the prospecting idea of gently inclined ore bodies and completed the task ahead of schedule.

　　In 2021, Zhang Peng became the head of Sudan Project Department. Slowly, the wife understood that the husband’s job is to travel through mountains and rivers, not to travel around. "Only when the country is rich and strong, and the six teams are stable, our small family will be happy." The wife said.

　　"On Team Six, everyone is good." Ding Zhengjiang, the captain of the Sixth Team, said, "The road ahead is long, and we should carry forward ‘ Hero Geological Team ’ Fine traditions, and strive to explore big gold mines for the country. "

　　■ Reporter’s Notes

　　Adhering to the heart of serving the country by geology

　　Mount Everest, more than 8000 meters above sea level, is an unattainable height for many people. During the interview, a set of figures was shocking: "Since its establishment in 1958, the six teams have identified more than 2,810 tons of gold resources and completed drilling footage of more than 5 million meters, which is equivalent to drilling through more than 600 Mount Everest!"

　　This set of figures is the result of the blood and sweat of the six teams. In the early days of the founding of New China, the older generation of prospectors set foot on the road of searching for gold … … For the cause of the motherland, they neglected their families, paid precious youth, and some even gave their lives.

　　After more than 60 years of hurricane and rain, some of the first generation explorers of the Sixth Team have passed away, but the spirit of faith, concentration on prospecting for mines and sincere service to the country is still passed on. They are full of blood, pack up their bags, climb mountains and follow the footsteps of their predecessors … …

　　In the interview, the words of an old comrade impressed the reporter: "Gold is not full of red, but the heart of a child is full of red." Faith can move mountains. It’s a long way to find gold. I hope the Sixth Team will carry forward the past and carry forward the cause, uphold the spirit of serving the country by geology, and strive to write a new chapter of "Hero Geological Team" in the new round of breakthrough in prospecting.

Meituan’s lawyer’s letter of living expenses is a legal document issued by Meituan’s financial department for users and law firms with outstanding loans. This is usually a formal warning to remind users that they have failed to fulfill the agreed obligations in the loan contract and urge them to repay as soon as possible. It usually comes from the legal means that users will take further when they are in arrears for a long time or have failed to collect for many times. After receiving the lawyer’s letter, the user may face further legal investigation, which needs to be taken seriously and dealt with in time.

After receiving the letter from the lawyer of Meituan’s living expenses, users need to realize that this is not just an ordinary collection, but a prelude to possible legal procedures. If the outstanding loan is ignored or continued, the collector may apply to the court for prosecution. After the court ruling, users may face enforcement measures, such as freezing bank accounts, inquiring about property status or even losing the right to dispose of some property or assets under their names. If the user is included in the list of people who have broken their trust, it may also affect normal life and credit activities, such as restricting high consumption, restricting the application for loans or credit cards. In order to avoid these consequences, measures should be taken in time after receiving the lawyer’s letter.

After receiving the letter from the living expenses lawyer of Meituan, it is necessary to confirm the authenticity of the letter. Usually, a formal lawyer’s letter will clearly indicate the name, address and contact information of the law firm, with the lawyer’s signature or firm seal attached. Users can verify the source of the letter by official website of the law firm or calling the public telephone. The customer service channel of Meituan’s living expenses is also an important way to confirm. You can directly call the customer service of Meituan Financial Platform for verification. Don’t call the strange private number in the letter at will, and beware of fraudsters committing fraud in the name of lawyer’s letter.

When you receive the letter from the lawyer of the US Mission’s living expenses, don’t panic or ignore it. Contact the official customer service department of Meituan at the first time to find out the unpaid amount, interest accumulation and specific situation, and confirm the authenticity of the letter. If it is true that the overdue payment is overdue, you should try to negotiate with the US delegation-explain your financial difficulties and strive for a plan of deferred repayment or installment repayment. You can also consult a lawyer to confirm whether you have any legal rights to claim. If you are unable to repay the debt, you can consider signing a written repayment agreement with the platform, and don’t delay the handling at will, otherwise it will have more serious legal consequences.

Receiving a letter from a lawyer of the US Mission’s living expenses does not mean that it will definitely face legal proceedings immediately. The lawyer’s letter is more of a warning to the borrower, urging the other party to fulfill its contractual obligations as soon as possible. Whether it will be prosecuted or not depends on the user’s subsequent reaction and attitude towards the letter. If the user pays off quickly after receiving the lawyer’s letter or reaches a repayment agreement with Meituan, it is usually less likely to sue; On the contrary, if users continue to default or fail to respond, they are more likely to be sued. Users should actively respond to lawyers’ letters and try to reach a settlement with Meituan before litigation.

The overdue Meituan living expenses loan has already had an impact on the user’s credit record. If the user fails to repay the loan on time, the default record will be reported to the central bank’s credit information system, which will seriously affect personal credit information. The receipt of a lawyer’s letter shows that the overdue situation has become more serious and the credit risk of users has already appeared. After being sued, once the court decides that the borrower needs to perform the contract and refuses to perform it, it may be included in the list of people who have lost their trust (commonly known as "Lao Lai"), which greatly lowers the personal credit score. After receiving the lawyer’s letter, we should try our best to solve the problem through consultation to avoid credit stain.

Generally, the lawyer’s letter of the US Mission’s living expenses will explain the specific amount that the user needs to repay, including principal, interest, late fees, attorney fees and other related expenses. These fees are calculated according to the terms of the loan contract or the platform agreement, and users need to check them item by item. For example, the late payment fee is the penalty fee due to overdue, while the lawyer’s fee is the cost incurred by the platform to hire a law firm to send letters and subsequent possible lawsuits. Some interest may be calculated on a daily basis, which also requires users’ special attention. If you are in doubt about the details of the fee, you should contact the relevant departments as soon as possible to verify.

The core of preventing receiving the letter from the lawyer of the US Mission’s living expenses is to fulfill the repayment obligation on time. Users need to evaluate their repayment ability and plan the loan amount and term reasonably before borrowing. In the process of repayment, we should pay attention to the monthly repayment time and try to prepare repayment funds in advance. In case of sudden financial difficulties, you should contact Meituan’s living expenses customer service in time, explain the situation and apply for deferred repayment or adjust the repayment plan. Reminders can be set, such as mobile phone calendar reminder or binding automatic deduction, to ensure that the repayment time limit is not missed due to negligence, and to fundamentally avoid receiving a lawyer’s letter.

　　This newspaper (reporter Zhao Xin) went shopping, and I don’t know how many citizens paid attention to the songs played in the store. Yesterday, the Internet began to spread that "the sudden change of songs in shopping malls is a mysterious hint", reminding consumers that hot songs are "anti-thieves". Is there such a "hint"? Yesterday, reporters contacted many shopping malls in Wuhan, and some shopping malls said that this prevention mechanism does exist. Have you ever encountered such a "hint" when shopping?

　　"pay attention! The change from soothing songs to energetic songs in shopping malls is to remind people who are used to stealing admission. " Yesterday, netizen @ Oregon Seven Sisters said that she tried on shoes when she was shopping in the mall many years ago. The light music originally played turned into a strong song. The salesperson told me that there was a habitual thief entering the mall. After the security guard found it, he informed the studio to remind him. This blog post was forwarded by the majority of netizens, saying that they had encountered similar situations. Some netizens also expressed doubts, saying that the sudden change of genre may be just a coincidence.

　　Is there such a "secret code" in the mall? Do local shopping malls in Wuhan have their own reminder system? Yesterday, the reporter found out from Guoguang, World Trade Organization, China Merchants, Qunguang, Ikea Huiju and other large shopping malls that some shopping malls did implement this code law. According to the staff from Qunguang, they will use this method to remind employees that there are fixed tracks for different phenomena, but the song list is not convenient to publish. The gathering of Zhongshang Square and IKEA also indicates that there are similar early warning methods. "In fact, this is just a sudden emergency mechanism." According to the relevant person in charge of a shopping mall, the public security environment and security have improved, and it is difficult to use the song-changing code. If thieves appear, they will directly intercept them at the scene to create a safe shopping environment for the citizens.
