CCTV News:Recently, the problem of sulfur dioxide exceeding the standard in Linfen City, Shanxi Province has aroused widespread concern. As a typical resource-based city in the north, the ambient air quality in Linfen City has turned sharply since the winter of 2016, and heavy smog weather has continued to appear. Up to now, Linfen City has experienced six heavy pollution weather processes, which lasted for 48 days and issued 13 heavy pollution weather warnings. On January 4, 2017, the air quality index (AQI) of monitoring points in Linfen City continued to rise, and the concentration of SO2 (sulfur dioxide) was as high as 1,300 μ g/m3, exceeding the national third-class standard ("minimum requirements for people to be exposed to acute health damage in the short and medium term") by more than 1,000, ranking first in 388 cities in China, 719 higher than the second.

On the 15th, Shanxi Provincial Environmental Protection Department announced that after three days’ investigation and analysis, the joint expert group of the Ministry of Environmental Protection and Shanxi Province has preliminarily identified five reasons for the excessive concentration of sulfur dioxide in Linfen:

First, coal consumption is large.From 2013 to 2016, the city’s coal consumption in Linfen increased from 30 million tons to 36.6 million tons, of which coking coal accounted for a high proportion, accounting for 65.3%, followed by power generation coal of 9.7 million tons, accounting for 26.5%.

Second, residents’ loose coal combustion emissions have aggravated sulfur dioxide pollution in winter.According to preliminary estimates, the annual sulfur dioxide emissions from coal-fired heating (except cogeneration) in six counties and cities (districts) along the Fenhe River in Linfen City are about 38,000 tons, accounting for 45% of the annual sulfur dioxide emissions. When winter enters the heating season, the proportion is even more prominent, accounting for about 70%. Among them, the emissions from heating boilers other than cogeneration account for 13% of the living sources.

Third, the promotion and use of clean coke did not achieve the expected results.Although clean coke is widely used in urban areas, due to its high burning point and difficulty in bank up, some people abandon the distributed clean coke, some mix clean coke with inferior coal, and a small number of clean coke fail to meet the sulfur index, and the amount of sulfur dioxide emitted by residents in urban areas and surrounding areas is still large.

Fourth, the transformation of coal-fired heating boilers and clean energy lags behind.At present, there are still 86 130-ton coal-fired boilers in urban areas, and there are basically no desulfurization measures. Although clean coke is used, the sulfur dioxide emission is still very large, which has a direct impact on the sulfur dioxide index in urban areas.

Fifth, there is no on-line monitoring for central heating in Dongcheng, the desulfurization device is ineffective, the factory area is messy and the management measures are not in place.(CCTV reporter Hu Xiaodong)

Baidu antigen-antibody structure prediction model is far more effective than AlphaFold3.

According to Baidu AI, in the research and development of antibody drugs and polypeptide drugs, the prediction of antigen-antibody and polypeptide protein complex structure plays a vital guiding role, and its accuracy is very important for subsequent research. However, from the current calculation methods, whether it is the energy function tool based on physical method or the method based on deep neural network, including the recently updated AlphaFold 3 of DeepMind, there is still much room for improvement in the structural prediction accuracy of antigen-antibody and protein-polypeptide complexes. In response to this challenge, PaddleHelix team of Baidu propeller developed HelixFold-Multimer model. By optimizing data, network structure and training methods, it has reached the leading position in the industry in predicting the structure of antigen-antibody/polypeptide protein complex. Compared with the existing methods, HelixFold-Multimer is far superior to similar methods, including the newly released AlphaFold 3, in two core key indicators: DockQ and success rate.

　　Covid-19 is thought to originate from bats, and it is 96.2% similar to RaTG13 (collected by Shi Zhengli, Wuhan Institute of Virology, Chinese Academy of Sciences, in Yunnan, China in 2013) in nucleotide sequence level. However, it is a kind of novel coronavirus that has not been detected in humans and other animals before, and its appearance has brought many new problems to be solved urgently, including whether other pets, livestock and poultry may be infected by Covid-19 besides humans?

　　On April 8th, local time, the top academic journal Science published the paper "Susceptibility of Ferrets, Cats, Dogs, and Different Domestic Animals to SARS-coronavirus-2" online. The purpose of this study is to find out some questions: Will Covid-19 be transmitted to other animal species, thus becoming a "reservoir" of infection? Covid-19 infection has many clinical manifestations in humans, ranging from mild infection to death, so how is it manifested in other animals? With the development of vaccines and antiviral drugs, which animals can be used to simulate the effects of these drugs or vaccines on humans most accurately?

　　In order to solve these problems, research teams from the State Key Laboratory of Veterinary Biotechnology of Harbin Veterinary Research Institute of Chinese Academy of Agricultural Sciences and the National High-level Biosafety Laboratory of Animal Disease Prevention and Control evaluated the susceptibility of different model experimental animals, pets and livestock to Covid-19, infected Covid-19 through experiments, observed the clinical manifestations and pathological changes of vaccinated animals and cohabiting animals, and detected the viral load of organs and tissues, the emission of respiratory and intestinal viruses, and the seroconversion of antibodies against Covid-19 in animals.

　　Their research shows that Covid-19 has weak replication ability in dogs, pigs, chickens and ducks, but it can replicate efficiently in ferrets’ upper respiratory tract and cats’ respiratory system and digestive system. Experimental infected cats can spread Covid-19 through the air; Some cats can cause serious illness or even death after infection, and the illness of young cats is obviously more serious than that of older cats.

　　Histopathological observation confirmed that virus infection in cats can cause lung inflammation and intestinal mucosal damage to varying degrees. Immunohistochemical study showed that there were a large number of virus infections in mucosal epithelium and olfactory bulb cells of upper respiratory tract (nasal cavity, maxilla, tonsil), mucous gland epithelial cells of trachea and bronchial mucosa, and intestinal mucosal epithelium.

　　The correspondent of this paper is Chen Hualan, academician of China Academy of Sciences, chief scientist of the innovation team of animal influenza basic and prevention research in Harbin Veterinary Research Institute of China Academy of Agricultural Sciences, Bu Zhigao, director of Harbin Veterinary Research Institute of Chinese Academy of Agricultural Sciences and director of the national high-level biosafety laboratory for animal disease prevention and control, and Wu Guizhen, secretary of the Party Committee of Institute of Viral Disease Prevention and Control of China CDC and director of BSL-3 laboratory. Previously, on March 31st, local time, the research team had taken the lead in publishing the research on the preprint platform bioRxiv.

　　It is worth mentioning that the National High-level Biosafety Laboratory for Animal Disease Prevention and Control is one of the existing two P4 laboratories in China, and the other is in Wuhan National Biosafety Laboratory of Chinese Academy of Sciences. All the experiments of Covid-19 infection in this study were carried out in P4 laboratory, which was approved by the Ministry of Agriculture and Rural Affairs of China. Animal research and animal welfare programs were approved by the Animal Experimental Ethics Committee of China Academy of Agricultural Sciences.

　　According to the press release issued by official website, Harbin Veterinary Research Institute of Chinese Academy of Agricultural Sciences, different coronaviruses have been prevalent in mammals and poultry, but most of these coronaviruses are limited to specific species of animals and generally cannot infect humans. Similarly, several common coronaviruses in humans do not infect other animals. However, some coronaviruses from bats, such as SARS and MERS virus, can often infect many animals and humans.

　　At present, Covid-19 is popular among a wide range of people in the world, and the risk of introducing animals in close contact with human beings is increasing. Therefore, it is urgent to study the susceptibility of domestic animals in close contact with human beings to Covid-19, evaluate whether domestic animals are exposed to Covid-19 hazards and become potential intermediate hosts, and provide scientific basis for prevention and control of Covid-19.

　　In addition, in view of the current global epidemic situation of COVID-19, it is very likely that it will evolve into a common infectious disease, and it is urgent to establish a stable and reliable animal infection model to meet the needs of vaccine and drug research and development evaluation.

　　The research team stressed that the monitoring of cat COVID-19 should be regarded as an auxiliary means to eliminate the current Covid-19 epidemic. They called for close monitoring and protection of cats in epidemic areas, avoiding their contact with infectious sources and preventing them from becoming possible transmission hosts or storage hosts.

　　In addition, it was previously questioned that cats infected with COVID-19 were caused by large doses under laboratory conditions. However, in addition to this research, on April 3rd, Academician Jin Meilin, professor of the State Key Laboratory of Agricultural Microbiology of Huazhong Agricultural University, director of the Key Laboratory of Veterinary Diagnostic Preparations of the Ministry of Agriculture, director of the Research Center for Emerging Infectious Diseases of Wuhan Institute of Virology, Chinese Academy of Sciences, and researcher Shi Zhengli, director of the Key Laboratory of Highly Pathogenic Biology and Biosafety of Chinese Academy of Sciences, also published a study on the preprint platform bioRxiv. Through the investigation of cat serum, they found that the serum ELISA test of 102 cats collected after the outbreak of COVID-19 in Wuhan showed that the serum from 15 cats (14.7%) was positive for Covid-19 receptor binding domain (RBD).

　　Nadia, a 4-year-old tiger from Bronx Zoo in new york, USA, was recently diagnosed with Covid-19. On April 5, local time, the US Department of Agriculture issued a statement confirming that a tiger in a zoo in new york was diagnosed with Covid-19, and several other lions and tigers also showed symptoms of respiratory diseases. Officials at the Bronx Zoo in new york said that nadia, three other tigers and three African lions had symptoms of dry cough and loss of appetite, but they are expected to recover. Public health officials believe that these animals were infected by an asymptomatic employee.

　　Covid-19 can be replicated in the upper respiratory tract of ferrets for up to 8 days, but it will not cause serious illness or death.

　　Ferrets are often used as animal models of human respiratory viruses. Therefore, the research team first tested ferrets’ sensitivity to Covid-19.

　　Two Covid-19 strains were used in this study: F13-E from Wuhan South China Seafood Market and CTan-H from a patient infected with Covid-19.

　　The research team inoculated 10 5 PFU (Plaque Forming Unit) F13-E or CTan-H into ferrets through nose respectively, and euthanized them on the 4th day after inoculation (P.I.). The turbinate, soft palate, tonsil, trachea, lung, heart, spleen, kidney, pancreas, small intestine, brain and liver of each ferret were collected, and the viral RNA was determined by qPCR and virus titration.

　　Viral RNA：A in ferrets’ organs or tissues: A, F13-E, B, CTAN-H..

　　The results showed that viral RNA and infectious virus were detected in the turbinate, soft palate and tonsil of all four ferrets, but not in other tissues.

　　C, virus titer in organs or tissues of ferrets inoculated with F13-E, D and CTAN-H.

　　The research team believes that these results show that Covid-19 can replicate in the upper respiratory tract of ferrets, but it has not been detected in other tissues.

　　In order to study the replication dynamics of virus in ferrets, the research team intranasally inoculated 6 ferrets with 10^5pfu of F13-E(3) or CTan-H(3), and then placed them in three isolated cages. On the 2nd, 4th, 6th, 8th and 10th day, ferret nasal wash and rectal swab were collected for virus RNA detection and virus titration. At the same time, their body temperature and COVID-19 signs were monitored for two weeks.

　　Viral RNA in the nasal wash of ferrets inoculated with F13-E(E) and CTan-H(F). Viral titers in the nasal wash of ferrets inoculated with F13-E(G) and CTan-H(H).

　　The results showed that viral RNA was found in the nasal wash of all six ferrets on the 2nd, 4th, 6th and 8th day. Viral RNA was also found in some rectal swabs, but the copy number was significantly lower than that of nasal wash. Infectious virus was detected in nasal wash of all ferrets, but none of them was found in rectal swab.

　　One ferret in each group developed fever and loss of appetite on the 10th and 12th days respectively. In order to investigate whether these symptoms are caused by virus replication in the lower respiratory tract, the research team euthanized the two ferrets on the 13th day and collected their organs for virus RNA detection.

　　However, except for the ferret turbinate inoculated with CTan-H, the low copy number was detected, and no viral RNA was detected in any other tissues or organs.

　　Pathological studies showed that two ferrets euthanized on the 13th day had severe lymphoplasmacytic vasculitis and vasculitis, the number of type II alveolar cells, macrophages and neutrophils in alveolar septa and alveolar cavities increased, and the lungs had mild bronchiolitis.

　　The asterisk indicates that the animals were euthanized on the 13th day after inoculation, and the other four animals were euthanized on the 20th day.

　　Covid-19 antibody was detected in all ferrets by ELISA and neutralization test, and the antibody titers of two ferrets euthanized on the 13th day were significantly lower than those euthanized on the 20th day.

　　In order to further study whether Covid-19 was replicated in ferrets’ lungs, the research team inoculated 8 ferrets with 10^5 pfu of CTan-H through trachea, and euthanized 2 animals on the 2nd, 4th, 8th and 14th days, respectively, and detected virus RNA in tissues and organs.

　　Among the two ferrets euthanized on the second day and the two ferrets euthanized on the fourth day, the researchers only detected viral RNA； in the turbinate and soft palate of one of them. Among the two ferrets euthanized on the eighth day, viral RNA； was detected in the soft palate of one ferret and in the turbinate, soft palate, tonsil and trachea of the other ferret. No viral RNA was detected in the two ferrets euthanized on the 14th day.

　　These results indicate that Covid-19 can replicate in the upper respiratory tract of ferrets for up to 8 days without causing serious illness or death.

　　At the end of the paper, the research team also mentioned that, comparatively speaking, Covid-19 is different from other influenza viruses that can replicate in the upper respiratory tract and lower respiratory tract of ferrets, and even human SARS-CoV. Covid-19 is only replicated in ferrets’ nasal bones, soft palate and tonsils. It can also replicate in the digestive tract, but even if the virus is inoculated in the trachea, the virus is still not detected in the lungs of ferrets.

　　Cats are highly susceptible to "cat-to-cat transmission": the monitoring of cat Covid-19 should be regarded as an auxiliary means of epidemic prevention and control.

　　It is worth noting that cats and dogs are in close contact with humans, so the research team thinks that besides laboratory animals like ferrets, it is very important to know the susceptibility of domestic animals that often live with humans to COVID-19 for the control of Covid-19.

　　The research team first studied the replication of Covid-19 in cats. Five 8-month-old subadult domestic cats (inbred lines) were intranasally inoculated with 10^5pfu of CTan-H, and two of them were scheduled to be euthanized on the sixth day to evaluate the virus replication in their organs. Three cats were put in separate cages in the isolator. In order to monitor the spread of respiratory droplets, an uninfected cat was placed in a cage adjacent to each cat vaccinated with the virus.

　　Because 8-month-old cats are aggressive, it is difficult to carry out routine nasal cleaning on them. In order to avoid possible harm, the research team collected the feces of these cats and checked the viral RNA in their organs after euthanasia.

　　Virus RNA was detected in the nasal bone, soft palate and tonsils of two sub-adult domestic cats euthanized on the 6th day, and virus RNA was also detected in the trachea of one cat and the small intestine of the other cat. However, no viral RNA was detected in any lung samples of these two cats.

　　Infectious viruses were detected in the nasal bones, soft palate, tonsils and trachea of these cats, but no infectious viruses were found in the small intestine with positive viral RNA.

　　The spread of Covid-19 among cats.

　　In the study of virus transmission, RNA virus was detected in the feces of two vaccinated cats on the third day, and RNA virus was detected in the feces of all three vaccinated cats on the fifth day. Among the three cats at risk of virus exposure, viral RNA was detected in the feces of one cat on the third day.

　　Virus-infected cats with positive feces were euthanized on the 11th day. Virus RNA was detected in the soft palate and tonsils of the infected cats and in the nasal bones, soft palate, tonsils and trachea of the exposed cats, indicating that respiratory droplets spread between cats.

　　On the 12th day, the research team euthanized the remaining cats. Viral RNA was detected in the tonsils of one virus-infected cat and the nasal bone, soft palate, tonsils and trachea of another virus-infected cat, but it was not detected in any organ or tissue of the two virus-exposed cats.

　　Through ELISA and neutralization test, Covid-19 antibody was detected in all three cats inoculated with virus and one cat exposed to virus.

　　Covid-19 replicates efficiently in respiratory system and digestive system of infected cats, causing pathological damage and inflammatory reaction. Histopathological and immunohistochemical study on cats that died or were euthanized three days after virus infection. (a) The arrangement of nasal mucosa epithelium is disordered, cilia fall off (arrow), and lymphocytes in lamina propria infiltrate (arrow). (b) The tonsil epithelial cells are degenerated and necrotic, and the surface of mucosal epithelium (asterisk) is covered with cell fragments and neutrophils (arrow). (c) Epithelial degeneration and necrosis of tracheal mucosa (arrow), with mucus (asterisk) mixed with a large number of cell fragments on the surface. (d) Epithelial necrosis of tracheal mucous glands and infiltration of lymphocytes (arrow). (e) Normal lung tissue structure of uninfected cats. (f) Aggregation of inflammatory cells in pulmonary blood vessels and coagulation of fibrin (arrow). (g) A large number of macrophages and lymphocytes infiltrated in alveoli, that is, alveolar septa. (h) Infiltration and proliferation of alveoli and alveolar septitis. (i) Some cells in the epithelium of small intestine are degenerated and necrotic, and lymphocytes in the lamina propria are moderately infiltrated (arrow). (j) A large number of epithelial cells of turbinate mucosa were positive for virus antigen (brown). (k) A large number of exfoliated cells in tonsil mucosa epithelium and mucosa surface were positive for virus antigen (brown). (l) A large number of virus antigens were positive (brown) in serous cells of tracheal mucous glands. (m) A large number of small intestinal mucosal epithelial cells were positive for virus antigen (brown). Ruler line A, I = 100 μ m, B-H, J-L = 200 μ m, M = 500 μ m

　　The research team also repeated the above-mentioned replication and transmission research in sub-adult cats in young cats (70-100 days). Histopathological studies on the samples of young cats who died or were euthanized on the third day after being inoculated with the virus showed that the nasal cavity and tracheal mucosa epithelium and lungs of the two cats had a lot of damage.

　　These results indicate that Covid-19 can be effectively replicated in cats, and young cats are more susceptible to infection. More importantly, the virus can spread from cat to cat through respiratory droplets.

　　Next, the research team also studied the replication and spread of Covid-19 in dogs, and the results showed that dogs were less sensitive to Covid-19. Similar studies also show that pigs, chickens and ducks are not sensitive to Covid-19.

　　Overall, the research team found that ferrets and cats are highly sensitive to Covid-19, dogs are less sensitive, and domestic animals including pigs, chickens and ducks are not sensitive to the virus.

　　In addition, it is reported that Covid-19 uses angiotensin-converting enzyme 2 (ACE2) as its receptor to enter cells, and ACE2 is mainly expressed in type II lung cells and serous epithelial cells of ferrets’ tracheal-bronchial submucosal glands. Therefore, the research team believes that the potential mechanism to prevent Covid-19 from replicating in ferrets’ lower respiratory tract remains to be studied.

　　The results of this study show that ferrets can be used as animal models for vaccine and drug evaluation in Covid-19. Dogs, pigs, chickens and ducks are not susceptible to Covid-19, which has important guiding significance for the traceability of virus hosts; More importantly, cats are highly susceptible to Covid-19.

　　The research team called for close monitoring and protection of cats in epidemic areas to avoid contact with infectious sources and prevent them from becoming possible transmission hosts or storage hosts. The monitoring of cat COVID-19 should be regarded as an auxiliary means to eliminate the current Covid-19 epidemic.

    Xinhua News Agency, Beijing, March 6th　Question: How do you view China’s price movement? -The second question and answer of China economy in the two sessions.

    Xinhua News Agency reporter Wei Yukun and Wu Yu

    Since last year, China’s price increase has been running at a low level, which has aroused some people’s worries about China’s deflation. How to treat China’s price movement situation? Is China’s economy really in deflation?

    During the two sessions of the National People’s Congress, the reporter interviewed many NPC deputies, Chinese People’s Political Consultative Conference members and authoritative experts to analyze this issue and respond to external concerns.

   Does low prices mean deflation?

    Since October last year, the consumer price index (CPI) has been declining year-on-year, and it will drop by 0.8% in January 2024. At the same time, the national producer price index (PPI) continued to decline.

    The low price has caused some worries about whether China’s economy will fall into deflation.

    To judge whether we are caught in deflation, we must first clarify the concept. Generally speaking, in economics, deflation mainly refers to the continuous negative growth of prices and the downward trend of money supply, which is usually accompanied by economic recession. This depends not only on the "shape" of price operation, but also on the "state" of money supply and the "potential" of economic development.

    -Price operation: generally low, maintaining a moderate upward trend.

    According to the government work report submitted for deliberation on the 5th, the consumer price of China residents rose by 0.2% in 2023. This data is in stark contrast to the high inflation in major developed economies.

    Jin Li, member of Chinese People’s Political Consultative Conference and vice president of south university of science and technology of china, said that last year, the core CPI excluding volatile food and energy prices rose by 0.7% year-on-year, indicating that the supply and demand of industrial consumer goods and service consumption in China were generally stable. The year-on-year decline of PPI also decreased by 5.4% from the highest in June last year to 2.5% in January 2024.

    Since last year, China’s monthly price level has always fluctuated moderately within a reasonable range. In January 2024, CPI rose by 0.3% month-on-month, which has been rising for two consecutive months.

    -Money supply: the total amount is moderate and the rhythm is stable.

    By the end of January 2024, the balance of broad money (M2) in China was 297.63 trillion yuan, up 8.7% year-on-year. Under the background of high base in the same period last year, it maintained a reasonable growth rate.

    The scale of social financing is a comprehensive indicator of financial support for the real economy. In January, the scale of social financing in China increased by 6.5 trillion yuan, 506.1 billion yuan more than the same period of last year.

    -economic development: the overall recovery is improving.

    In 2023, China’s economy generally rebounded, with a GDP growth rate of 5.2%, which was faster than the average growth rate of 4.5% in the three years of the epidemic, and also significantly faster than the economic growth rates of 2.5% in the United States, 0.5% in the euro zone and 1.9% in Japan, making it an important engine of global economic growth.

    Since 2024, China’s manufacturing purchasing managers index, SME development index and other indicators have rebounded from last December. The International Monetary Fund (IMF) recently raised its forecast for China’s economic growth this year and cast a "vote of confidence" for China’s economy.

    "Deflation is often the result of long-term accumulation of structural problems in economic operation. Judging deflation should not only focus on one or two price indicators." Huang Maoxing, deputy to the National People’s Congress and vice president of Fujian Academy of Social Sciences, said that on the whole, there is no deflation in China, let alone deflation spillover, and the so-called "economic deflation in China" is totally a false proposition.

    Not long ago, ING reported that the discussion about deflation in China was exaggerated by the outside world. In January, the overall CPI and core CPI in China both rose month-on-month, reflecting that China has not fallen into a "deflation spiral".

    "We don’t expect an overall deflationary trend in China." Gita Gopinath, First Vice President of IMF, said not long ago.

   What are the reasons for the low price increase?

    Prices are related to economic operation and affect people’s lives. At present, the low price increase in China is the result of multiple factors.

    "After the smooth transition of epidemic prevention and control, domestic production has accelerated recovery, logistics has remained smooth, and product supply is sufficient. However, demand is constrained by factors such as expected instability and income distribution differentiation, and recovery will take some time." Xu Guangjian, vice president of China Price Association, said that the time difference between supply and demand recovery is the main factor for the lower prices.

    Commissioner Jin Li said that in 2022, due to the Ukrainian crisis, food and energy prices were higher, which made the CPI increase in 2023 relatively low. In addition, the price of pork occupies a high weight in China CPI. Due to the abundant supply of live pigs and pork and the sluggish consumption of superimposed pork, the domestic pig price continues to fall, which lowers the CPI increase.

    Input factors also have an impact on China’s prices. After the epidemic, in order to cope with high inflation, major central banks in the United States and Europe quickly and intensively adjusted their monetary policies, and the year-on-year increase of CPI in the United States and Europe has dropped from the previous high of about 10% to the current 3%. "The inflation level in developed economies has fallen faster than expected, which has an impact on the price level in China." Pan Gongsheng, governor of the People’s Bank of China, said.

    Xing Ziqiang, chief economist of Morgan Stanley in China, said that China’s lower prices may have a positive spillover effect on global trade goods prices, which will help alleviate the "sequela" of unconventional stimulus policies adopted by some economies in response to high inflation.

    The experts interviewed agreed that the factors that caused the current low price operation in China are mainly phased, cyclical and seasonal, not trending, and its influence should not be exaggerated.

    This year’s government work report sets the expected target of annual consumer price increase at around 3%. According to the plan report submitted for review on the 5th, the main consideration for setting this goal is to comprehensively analyze the hikes of price changes in 2023 and the new price increase factors in 2024. It is expected that consumer prices will rise moderately in 2024.

    "This expected goal is consistent with last year’s expected goal, in line with the overall trend of domestic price stabilization and recovery, and leaves some room for strengthening macro-policy regulation and deepening price reform." Yu Miaojie, deputy to the National People’s Congress and president of Liaoning University, said.

   How to prevent the risk of deflation?

    Delegates and experts interviewed said that although the low domestic price operation is temporary, we should be alert to and guard against deflation risks, and actively and effectively solve problems such as insufficient effective domestic demand and overcapacity in some industries.

    -Strengthening macro-policy control.

    The government work report pointed out that the liquidity should be kept reasonable and sufficient, and the scale of social financing and money supply should match the expected goals of economic growth and price level.

    "Maintaining a reasonable and sufficient liquidity is an effective measure to prevent deflation risks. This year’s government work has clearly promoted the steady decline of comprehensive social financing costs, which is expected to further stimulate the effective demand of the real economy and enhance residents’ willingness to consume and invest. " Ceng Gang, director of Shanghai Finance and Development Laboratory, said.

    A proactive fiscal policy should moderately increase efforts, improve quality and increase efficiency; A prudent monetary policy should be flexible, moderate, accurate and effective; Incorporate non-economic policies into the consistency assessment of macro-policy orientation … A number of arrangements in this year’s government work report have strengthened policy co-ordination to ensure that efforts are made in the same direction and joint efforts are formed.

    -Promote the formation of a virtuous circle in which consumption and investment promote each other.

    Han Baojiang, a member of Chinese People’s Political Consultative Conference and a professor at the Central Party School (National School of Administration), said that at present, the key to preventing deflation risks is to expand domestic demand, release the potential vitality of the super-large-scale market, and enhance the ability and confidence to resist external imported risks.

    When deploying this year’s tasks, the government work report pointed out that the implementation of the strategy of expanding domestic demand should be organically combined with deepening the structural reform on the supply side, so as to better coordinate consumption and investment and enhance the pulling effect on economic growth.

    Optimize the consumption environment, carry out the "consumption promotion year" activity and implement the "rest assured consumption action"; Deepen the cultivation and construction of international consumption center cities; Promote the construction of additional national debt projects with high quality; We will implement a new cooperation mechanism between the government and social capital, and encourage private capital to participate in major project construction … The government work report and the plan report will focus on expanding domestic demand this year.

    "With the implementation of a series of policies to expand domestic demand, giving full play to the key role of investment in optimizing the supply structure and promoting the upgrading of domestic consumption structure, the domestic economic cycle will be further smooth." Qu Yongyi, member of Chinese People’s Political Consultative Conference and secretary of the Party Committee of the Institute of Industrial Economics of the Chinese Academy of Social Sciences, said.

    Ayhan Gauss, deputy chief economist and director of the forecasting bureau of the World Bank, said that a series of policies adopted by China at present are very correct, which can boost consumer confidence and consumption in the short term, and enhance the long-term economic growth potential through firm reforms.

　 　 Special feature of 1905 film network In fact, the concept is not new, not to mention the amazing short film. In 2012, the animated film invited the protagonists of the game and turned it upside down. Up to now, Sony’s "Pixel Wars" has taken the road of combining real people with CG. Comedy stars such as adam sandler, kevin james and Josh Gad are invited. Obviously, the film didn’t want to be normalized from the beginning, and it was played in the guise of "war" and alien invasion, but it was still a shit and Loser transformation. It was not interesting or harmful.

　 　 At the beginning of the film, the film played a card of feelings and memories. Several strange-looking little boys, one of whom lost how to play the game, and the other, although brave, was defeated by others in the final championship battle. The other likes to chat with the girl in the game machine, full of small and medium-sized Xuan Xuan. Obviously, the film is paving the way, and it is also a common routine of Hollywood movies. Everyone’s adult life is greatly influenced by his childhood, so-called psychological trauma. So, the runner-up of the game, carrying the shadow of the second place, grew up to be an ordinary employee of a home appliance company, while the little fat man with no ambition and only catching dolls became the president of the United States. Yes, you are not mistaken. What is the screenwriter’s brain wide open for irony? Another "little devil" got into the panic, and the geek who is infatuated with beautiful women, as always, started a technical otaku.

　 　 When the scene jumps to the present, when adam sandler comes out, the whole style of painting is wrong, not to mention that kevin james has become the boss of the United States. From this time on, the tone of the film is slightly ironic and teasing. After watching such low-cost comedies in the United States, you will be quite familiar with and benefit from all kinds of jokes and techniques, such as ridiculing the American president to pieces and not knowing the "disaster". Isn’t it obvious that the president has no education? In addition, all kinds of important people in the White House have also become the object of ridicule, portrayed as a group of straw bags, officials are not like officials, and the general seems to be half buried in the ground. Of course, Americans haven’t forgotten to give a black hand to their good brother Britain again. The female prime minister has become thin and toothless, and looks like a menopausal woman with hormonal instability. She is not only pale but also very neurotic, which makes people think of her naked contempt for the Queen of England. Behind these satire and ridicule, what we can actually see is the characteristics of the film Pixel Wars, or the serious hooliganism as mentioned above.

　 　 Therefore, after adam sandler saw the heroine’s swaying posture, the first sentence she blurted out was "Wow", a heartfelt surprise brought out by hormones, and then the heroine happened to be in the emotional loss stage of life. Two people flirted and secretly fell in love, but they did not expect to start bickering because of a misunderstanding of a kiss, and they began to stage the plot of tell it to the judge. This way of communication between men and women is obviously the favorite of this kind of comedy, and they don’t like each other. Of course, adam sandler is not the only serious hooligan. Otaku still thinks about the dream girl in his game, and even draws many cartoons full of psychosexuality. One of the conditions for the little devil to join the team against alien aggression is to have dinner with tennis superstar Serena and spend the night together.

　 　 The more the film goes to the back, the stronger the desire of these men for women, and the creator has generously satisfied all their wishes. After becoming a salvation star, adam sandler won the beauty home, and the cartoon goddess of the otaku was regarded as a reward for the victory of the game, and became a real person, and Serena was waiting for the sandwich night that the little devil was thinking about … … It can be seen that these women were rewarded as trophies to these geeks, so when the beautiful game goddess in the movie dropped her double swords and leaned over to kiss the fat and filing otaku, the boys in the audience couldn’t help but make a sound with multiple meanings of regret, envy and jealousy.

　 　 It can be seen that "Pixel Wars" is like a beautiful world that a bunch of game geeks fantasize about themselves. In this world, not only can they become superheroes, but the opponents they beat are actually BOSS, who often can’t get through customs in the game, and then save the world. By the way, they also saved the setting that they have been a loser for the first half of their lives, and finally they can even win the beauty. Therefore, it is not surprising that the film is full of all kinds of imagination about beauty, hero and strength. After all, for the game otaku, the imagination of the external world is always better than the reality, otherwise Serena, a world champion who is strong and independent both physically and mentally, can’t throw herself at a cheating game champion.

　 　 It is precisely because of this that the audience of this "Pixel Wars" is estimated to be very limited. After all, the value position of such male chauvinism and taking all women as trophies is really out of line with the prevailing trend of feminism, not to mention that all the women in the movie are beautiful and amazing, while all the men seem to be a little diabetic.

"Pixel Wars" is such a typical American brainless comedy. The concept of pixels in the old-fashioned game of the film to create alien attacks is somewhat interesting in itself, but it is only limited to this. Wasted the setting and nostalgia that this attack method is electronic and gamified. On the one hand, the game characters in Pixel are much richer, and the story in the movie is still from a human perspective. On the other hand, they are all set as villains who will only destroy or even show their faces and break into slag, destroying their childhood and feelings in the game hall with steel.

　

This week, OPPO announced the latest technological progress in AI, performance, communication and privacy security, including the first handset/hands-free dual-mode satellite call for smart phones, the first 7 billion-parameter large model for end-side applications, the tidal architecture that debuted and many other cutting-edge technologies.

"

Thanks to the complete ANDES GPT 7 billion-parameter large language model applied by end-side, Find X7 series will bring the next generation AI experience such as natural language understanding, text content summary and call voice summary.

Compared with other models on the same platform, oppoandesgpt 7 billion parameter large language model can bring 20 times faster response in the generation of 200-word prefix, and 2.5 times faster for the generation of 2000-word prefix.

At the same time, OPPO’s AndesGPT can achieve the maximum number of abstract words of 14,000, which is 3.5 times that of other models on the same platform. In terms of generation quality, compared with the 1 billion parameter model, the ANDES GPT 7 billion parameter large language model has a higher "IQ" understanding ability, which brings a more complete and accurate record to the call summarization ability.

OPPO also announced the AndesGPT generative visual model based on self-training, which will bring image semantic understanding, subject recognition and segmentation, image extension and generation capabilities to Find X7 series, and bring a new functional experience of subject elimination and real-life redrawing. AndesGPT’s generative visual mode brings a wider range of image experience to mobile phones.

Compared with other cloud models on the same platform, AndesGPT can only support human body recognition. ANDES GPT not only supports the recognition and segmentation of more than 120 kinds of subjects, but also can realize hair-level segmentation and multi-agent separation of up to six, as well as the filling and natural generation of super-large-area images, which greatly expands the application scope and practicability of the generative visual model.

In addition, the end-to-end application of AndesGPT generative visual model also brings 60% shorter generation time and higher generation accuracy compared with other models on the same platform, bringing users a more readily available generative visual experience.

(3) Zhang Jinglin, deputy director of the Airport Intercity Railway Office of the Municipal Development and Reform Commission (Municipal Price Bureau), introduced the progress of Bozhou Airport, the progress of the Shanghai-Hangzhou high-speed railway, and the progress of the preliminary work of the Bobang-Huaifu intercity railway project.

1. Progress of preparatory work for Bozhou Airport Project

(1) Project progress. Bozhou civil airport project belongs to the preliminary work project of the national "Twelfth Five-Year Comprehensive Transportation System Planning". In February 2017, Bozhou Civil Aviation Airport Project was included in the National Civil Aviation Development Layout Plan for 2030 and the Civil Aviation Construction Plan for the Thirteenth Five-Year Plan. In January 2018, the National Development and Reform Commission entrusted China Civil Aviation Engineering Consulting Company to hold an evaluation meeting on the pre-feasibility study report of Bozhou Airport Project. In February 2018, China Civil Aviation Engineering Consulting Company issued an evaluation report and submitted it to the National Development and Reform Commission.

Avic design institute has been entrusted to prepare the feasibility study report of the project simultaneously, and the feasibility study report will be submitted for approval after the project is approved. At the same time, special supporting reports such as energy-saving assessment, social stability risk report, seismic safety assessment, environmental impact assessment, soil and water conservation plan and land pre-trial required in the feasibility study stage have been determined by public bidding and other means.

(2) There are problems. The Central Military Commission issued a document in March 2018, which put forward new requirements for the approval procedures of civil aviation airports: the military-land agreement signed between the theater and the provincial government must be submitted to the Central Military Commission for approval before it can take effect. After the document was issued, the General Office of the Military Commission is reviewing 37 civil aviation airports in China that have entered the examination and approval procedures, and determining the list of airports that implement the new regulations of the Central Military Commission through consultation. Bozhou airport project approval needs to wait for the audit results, and the National Development and Reform Commission will perform the approval procedures according to the situation.

(3) the lower work arrangement. Timely link up the National Development and Reform Commission and the Joint Staff, grasp the audit of 37 civil aviation airports that have entered the examination and approval procedures by the Central Military Commission, and coordinate and promote the project approval of Bozhou Airport.

Supervise AVIC Design Institute and East China Flight Procedure Institute to develop project feasibility study, aircraft performance and flight procedures; Supervise the preparation of special supporting reports such as energy-saving assessment, social stability risk report, earthquake safety assessment, environmental impact assessment, soil and water conservation plan and land pre-examination.

(Bozhou Airport is a civil regional airport. The short-term design target year of the project is 2025. It is predicted that the annual passenger throughput will be 550,000 passengers, the annual postal throughput will be 1,900 tons, and the annual aircraft take-off and landing will be 5,671 sorties. The main construction contents of this phase of the project are: the flight zone index 4C, a new runway with a length of 2,600 meters and a width of 45 meters, a vertical connecting taxiway, six station platforms with Class C seats, and air traffic control, oil supply facilities and public supporting facilities. The total investment of this project is about 860 million yuan. )

2. Progress of Shanghai-Hangzhou High-speed Railway

(1) Project situation. Shangqiu-Hangzhou Railway is the second channel project of East China North-South Railway in the Medium-and Long-term Railway Network Planning of Anhui Province, and it is listed in the National Twelfth Five-Year Comprehensive Transportation System Planning. The project starts in Shangqiu, Henan Province, passes through Bozhou, Fuyang, Huainan, Hefei, Wuhu and Xuancheng in Anhui Province, and Huzhou in Zhejiang Province to Hangzhou. The main line is 795 kilometers long, with a design speed of 350 kilometers per hour and a total investment of about 96 billion yuan.

(2) Overview of Bozhou section. The Shang-He-Hang Railway is 67 kilometers long in Bozhou, with three passenger stations, namely Bozhou South Station, Lumiao Station and Gucheng Station. The two major node projects are the Guohe Bridge and Gucheng Bridge.

In order to give full play to the driving role of high-speed rail in urban economy, our city actively strives for the adjustment of high-speed railway station from Bozhou Station to Bozhou South Station, and the scale of the station building is 15,000 square meters.

In order to realize the connection between Bobang Intercity and Beijing-Shanghai High-speed Railway and Shanghe-Hangzhou Railway, with the efforts of our city, the railway head office agreed to reserve the conditions of Bobang Intercity Access in Bozhou South Station in the preliminary design reply of Shanghe-Hangzhou Railway: the arrangement scheme of Shanghe-Hangzhou Yard and Bobang Yard shall be adopted, and the planning and design shall be based on three sets of seven lines in Shanghe-Hangzhou Yard and two sets of three lines in Bobang Yard; Recently, there are 6 arrival and departure lines (including main lines) and 2 platforms in Shanghe Hangchang Station.

(3) Project progress. Our city has established an integrated promotion mechanism in the urban area, and unified all relevant functional departments in the urban area under the leadership of the local work headquarters in Bozhou section of the Shanghe-Hangzhou Railway, which has reduced intermediate links and improved the promotion efficiency from the system setting. Under the guarantee of working mechanism, the construction of our city is progressing smoothly. Since the construction units of China Railway 21st Bureau, Electrification Bureau and 18th Bureau entered the site in December 2015, the project progress has always ranked first in the province. As of June 25th, the pier construction of Bozhou section of Shanghe-Hangzhou Railway has been fully completed. Subgrade ancillary works have been built.

The building of Bozhou South Station was built by China Railway Beijing Bureau and entered the site on April 20th.

In order to realize the consistency of architectural style and the synchronization of construction between Bozhou station square and station building, our city took the lead in carrying out the combined bidding for the planning scheme design of station square (government) and station building (railway), which was praised by the railway corporation. At present, the square in front of Bozhou South Station was built by China Construction First Bureau, and the foundation stone was laid on April 18th. The preliminary construction section of Bobang intercity railway (station building and tie line project) has started construction, and the pile foundation construction of the cross-business Hehang Bridge has been completed, and the pier construction is currently underway.

(4) The next step. Our office connects five construction units (China Railway 21st Bureau, Electrification Bureau and 18th Bureau), station building (China Railway Beijing Bureau) and plaza (China Railway 1st Bureau) every week to optimize the construction environment, coordinate and solve problems, fully promote the construction of Shanghai-Hangzhou high-speed railway, and ensure the realization of the goal and task of keeping the progress among the best in the province.

3. Preliminary work of Bobang-Huaifu intercity railway project.

In order to improve the traffic location advantage in northern Anhui and improve the layout of railway network, the Provincial Railway Office has carried out the compilation and approval of the Inter-city Railway Network Planning in northern Anhui. At present, the text of the Plan has been completed; In May 2017, the environmental impact report of the Plan was approved by the Ministry of Environmental Protection; At the end of 2017, the Plan was revised according to national requirements and reported again. The Plan includes the inter-city railways of Huai-Su-Fu and Bo-Bang.

The preliminary work of the inter-city railway project in northern Anhui Province was promoted by Anhui Investment Group. At present, the first draft of the Feasibility Study Report on the New Huaisu-Bengbo Express Railway has been compiled by China Railway Shanghai Design Institute. After the "North Anhui Intercity Railway Network Planning" is approved by the state, the provincial investment group will take the lead in joint venture with the cities to promote the project construction in accordance with the relevant policies of the Anhui provincial government’s upcoming intercity railway development opinions (extracting construction funds from land transfer fees, setting up a compensation mechanism, and comprehensive land development, etc.).

According to the convergence, in accordance with the deployment of the state to strictly control financial risks, the National Development and Reform Commission has successively issued policy requirements for urban rail transit and intercity railways. All provinces and cities must establish a fund-raising and loss-making mechanism, strictly control project loans, and suspend the approval of relevant plans in 2018. In the next step, we will put forward implementation suggestions based on the development opinions of provincial intercity railways and the development needs and stages of our city, and report to the municipal government to study and determine the construction timing of the Bo-Bang intercity railway, and carry out related work such as raising construction funds.

　　CCTV News:The annual year-end consumption peak season has arrived. In the consumption peak season of 2023, the reporter saw that consumer demand is more subdivided and vertical, consumption is more decentralized and personalized, and intelligent, experiential and high-quality products are exploding. From the industrial point of view, the diversity of consumer demand also promotes the trend of personalized production and flexible customization on the supply side.

　　Under the increasingly diversified consumer demand, refined home appliances are more sought after by consumers. The data of the e-commerce platform shows that the sales of smart home products that can enhance the sense of home life experience have increased significantly. Among them, the turnover of intelligent sensing faucets, intelligent door locks, intelligent lifting tables and other products all increased by more than 100% compared with the same period in 2022.

　　Healthy consumption has also become a kind of consumer goods with high willingness of consumers. According to the data of the platform, in the "Double Eleven" in 2023, the outdoor sports industry showed explosive growth, and the sales of cycling, skiing and out shoes clothing products increased by 300% year-on-year.

　　On the major e-commerce platforms, the reporter noticed that domestic brands are highly sought after by consumers. According to the data of China International Electronic Commerce Center Research Institute, in this peak consumption season, among the top 20 brands in online retail sales, domestic brands occupy 11 seats.

　　While the consumption trend changes, it is also promoting the transformation of the industry. Li Mingtao said that relying on the support of online big data, enterprises can more clearly understand the needs of consumers, and thus rely on personalized production and flexible customization to accurately match related needs.

　　Promote featured products and adopt various operation methods to cope with the sales peak.

　　The annual year-end consumption season is also an important node for enterprises to sprint annual sales. At present, local enterprises are actively enriching their means of operation and vigorously promoting local specialty products.

　　In Hanzhong, Shaanxi Province, the local digital economy industrial park jointly settled in enterprises, and launched online live broadcast and other activities for the first time to introduce local agricultural special products to consumers.

　　This company, located in Jiangmen, Guangdong Province, has developed a series of snack foods and organic foods based on local specialties such as Xinhui dried tangerine peel and Taishan rice. The person in charge of the company predicts that the sales volume of the company’s products will rise sharply this consumption season. In order to cope with the sales peak, the company made sufficient preparations in advance.

　　The new express delivery mode allows goods to reach consumers faster.

　　During the peak consumption season every year, the express delivery volume will explode. The growth of express delivery reflects the vigorous vitality of China’s consumer market. At the same time, how can consumers get the goods they ordered faster?

　　At a courier service outlet in Mianzhu City, Sichuan Province, the staff are busy scanning the code for express parcels, putting them on the shelves, and three shelves are filled with parcels stored on behalf of others.

　　It is understood that during the end-of-year consumption peak season in 2023, major express delivery companies in Mianzhu have increased their investment, and tried their best to reduce the phenomenon of express delivery squeeze and delay by increasing operating venues, adding automation equipment, expanding transportation capacity and increasing manpower.

　　In Jinhua, Zhejiang Province, relying on the mode of "integration of passenger and freight", express delivery can take the bus to the village, so that more rural people can enjoy the same timely delivery service as in the city, which greatly improves the timeliness of express delivery. Wu Chengrong, a villager in Shenfan Township, Jinhua City, just got his first package of this year’s "Double Eleven" a few days ago.

　　In addition, the local area also adopts the new logistics mode of "regional co-distribution", relying on the postal network, integrating the first-class distribution resources of each express brand village and town, and realizing the automatic sorting of all express brands in the same line. Postal couriers can complete the express transportation and delivery work of different express delivery companies, which greatly relieves the logistics pressure of the "last mile" in remote areas.

　　According to the monitoring data of the State Post Bureau, November 1 — On November 4th, the whole network collected 2.027 billion pieces of express delivery, up 16.1% year-on-year and 31.0% quarter-on-quarter, reaching a record high.

　　BEIJING, Nov. 18 (Xinhua)-Zhao Yingmin, vice minister of the Ministry of Environmental Protection, said on the 18th that the water environment quality in China is generally improving, but the situation is still grim, with widespread ecological destruction in river basins, non-point source pollution not effectively curbed, serious pollution in some tributaries, prominent eutrophication in some lakes, water environment carrying capacity reaching or approaching the upper limit, and "black odor" problems in many rivers and ditches flowing through towns. However, there is no contradiction between the overall improvement of the country and the local deterioration.

　　The the State Council Press Office held a routine briefing on the State Council policy today to introduce the policies related to the "Thirteenth Five-Year Plan" for eco-environment. For the reporter’s "‘ Water Ten Articles ’ Zhao Yingmin answered questions such as the progress made in one year’s implementation, what problems exist in water pollution prevention and control, and the focus of the next step.

　　Zhao Yingmin introduced that "Water Ten Articles" was released in 2015, and this year is the first implementation year, which has made great progress. Over the past year, there have been six main developments: First, according to the requirements of the "Water Ten Articles", the Ministry of Environmental Protection and 31 provinces (autonomous regions and municipalities) signed a responsibility letter for water pollution prevention and control, which decomposed the quality improvement tasks required by the "Water Ten Articles" into provinces one by one, and also required the provinces to decompose them into cities one by one, and finally implemented them in 1940 control units across the country. Each unit has clear and specific environmental quality for each year. At the same time, the Ministry of Environmental Protection has also established a national water pollution prevention and control mechanism, which has promoted the establishment of a linkage and cooperation mechanism for water pollution prevention and control in Beijing-Tianjin-Hebei, Yangtze River Delta and Pearl River Delta regions.

　　The second is to organize the compilation of water pollution prevention and control plans for key river basins, prevent and control water pollution in the whole process, promote water resources conservation and recycling, and strengthen ecological protection and restoration.

　　The third is to organize investigation and evaluation of the environmental protection status of more than 900 centralized drinking water sources in cities at prefecture level and above, and guide all localities to speed up the standardized construction of drinking water sources. This includes the delineation of drinking water source protection areas, and cleaning up illegal buildings and sewage outlets in the protection areas according to law.

　　Fourth, according to the requirements of water quality improvement, decompose and implement the targets and requirements for emission reduction of major water pollutants in the 13 th Five-Year Plan and 2016.

　　The fifth is to implement the task of comprehensively improving the environment of 130,000 newly established villages by 2020, implement the central rural energy conservation and emission reduction funds in 2016, and support all localities to continue to comprehensively improve the rural environment.

　　Sixth, a series of relevant technical documents have been issued to guide the implementation of the "Water Ten Articles" in various places, including the Technical Guide for the Preparation of Water Body Standards, and a series of other technical documents.

　　At present, this year is 1-mdash; Of the 1,922 monitoring sections with monitoring data in September, 1,351 were above Grade III, accounting for 70.3%, up 4.0 percentage points year-on-year. At the same time, it should also be noted that 166 are inferior to category V, accounting for 8.6% of the total, a year-on-year decrease of 1.2 percentage points. At present, we estimate that this year, as the first complete year of the implementation of the "Water Ten Articles", it should be said that it has achieved a good start, and the annual target set by the "Water Ten Articles" is expected to be completed on the whole.

　　Ying Zhao residents further pointed out that although the quality of water environment has been continuously improved through the efforts of the Twelfth Five-Year Plan, there is still a big gap compared with the people’s growing environmental demand. The prevention and control of water pollution is unbalanced, and the phenomenon of ecological destruction in river basins is still relatively common at present. It should be said that non-point source pollution has not been effectively curbed, some tributaries are seriously polluted, some lakes are eutrophic, the carrying capacity of water environment has reached or approached the upper limit, and many rivers and ditches flowing through towns are "black and smelly", which has been strongly reflected by the masses.

　　Zhao Yingmin also introduced three characteristics of the national water environment. First, the surface water quality is generally stable and getting better, but some water pollution problems are outstanding. Second, the situation of good water protection is grim. Third, the main pollution factors have differentiated. In the 12th Five-Year Plan, the binding index COD has declined, but the nitrogen and phosphorus are changing. Because the chemical oxygen demand has dropped a lot, relatively speaking, the pollutants that were originally in the second and third places have gradually become prominent pollution problems in some waters.

　　He said that the "Thirteenth Five-Year Plan" clearly put forward the goal and overall thinking by 2020. In the next step, the Ministry of Environmental Protection will insist on improving the quality of water environment as the core, take the implementation of the "Ten Water Articles" as the starting point, and conscientiously implement the tasks specified in the "Thirteenth Five-Year Plan". First, adhere to the problem orientation and solve the outstanding water pollution problem that the masses are most concerned about and strongly reflect. "1+2" work priorities. "1" is to pay close attention to the safety of drinking water. "2" starts from both good water and poor water. The so-called good water is a class III or above water body that has not been polluted at present, and protection should be strengthened; Poor water is the so-called "black and smelly" water body, which is inferior to Class V water body, and we should also pay close attention to treatment. The second is to do a good job in source prevention and strictly observe the red line of total space access. The third is to highlight key areas and strengthen governance measures. The fourth is to innovate management methods and improve the management ability of water environment quality. The fifth is to strictly implement the responsibilities of local and enterprises.

　　Ying Zhao residents further indicated that the water environment quality in China is improving year by year. It should be said that the improvement of environmental quality is supported by a large number of specific pollution control work. For example, in the past five years, the total discharge of chemical oxygen demand and ammonia nitrogen in China has decreased by 12.9% and 13%, and the daily sewage treatment capacity of cities and towns in China has increased by 57 million tons. Now the sewage treatment capacity of cities and towns in China has reached 182 million tons, making it one of the countries with the largest sewage treatment capacity in the world. There is still a lot of work, which supports the overall improvement of the water environment quality in the country, although the situation is still grim. Environmental protection inspectors found problems, and in some places, some sections of water quality deteriorated and rebounded, but there is no contradiction between the overall improvement of the country and the local deterioration.

　　He emphasized that this plan is very clear, and water environment protection should focus on water resources, water environment and water ecology, and the three should be comprehensively considered and treated to implement that "landscape, forest, field and lake are a community of life". In fact, water pollution control is manifested in water, but many problems still come from the shore, so it is necessary to form a systematic whole between water and land. Environmental management should also be managed in accordance with the objective laws of river basins, and refined management should be implemented, so as to implement the requirements of the 13 th Five-Year Plan and realize the protection of water resources, water environment and water ecology.
