Xinhua News Agency reporter Bai Yang

In March, a number of new regulations came into effect. 111 drugs were included in the new national medical insurance drug list; The new version focuses on controlling the list of new pollutants to defend the clear water and blue sky; The new regulations on cosmetics supervision strengthen the sampling inspection of children’s cosmetics and other products … more perfect rule of law, more secure protection.

111 drugs were included in the new national medical insurance drug list.

The new version of the national medical insurance drug list will be implemented on March 1.

The new national medical insurance drug list added 111 drugs, including 2 drugs for COVID-19, 7 drugs for rare diseases, 22 drugs for children, etc. Most of them were newly listed within 5 years.

The total number of drugs in the adjusted national medical insurance drug list reached 2967. After Azvudine Tablets and Qingfei Paidu Granules were included in the national medical insurance drug list, there are more than 600 drugs for treating COVID-19’s symptoms such as fever and cough in the national medical insurance drug list.

The new version of the list of key pollutants takes effect.

The 2023 version of the list of new pollutants under key control will be implemented on March 1.

New pollutants refer to toxic and harmful chemicals discharged into the environment, which have the characteristics of biotoxicity, environmental persistence and bioaccumulation, and pose great risks to the ecological environment or human health, but have not been brought into management or the existing management measures are insufficient.

The list defines 14 kinds of key new pollutants to be controlled and their environmental risk control measures such as prohibition, restriction and discharge restriction. Departments of ecological environment, industry and information technology, agriculture and rural areas, commerce, market supervision and management, and customs at all levels should strengthen the control and governance of new pollutants according to the division of responsibilities.

　　Xinhua News Agency, Zhengzhou, August 14th: Writing a picture of green development by running rivers — — Enlightenment from the continuous flow of the Yellow River for 20 years

　　Xinhua News Agency reporters Song Xiaodong and Liu Shiping

　　On June 26th, 2018, the Yellow River was photographed on the pontoon bridge between Wuba Town, Taiqian County, Henan Province and yinshan town, Dongping County, Shandong Province (photographed by panorama camera). Xinhua News Agency reporter Feng Dapeng photo

　　The surging river meanders like a golden ribbon eastward into the sea. In people’s impression, "how the Yellow River’s waters move out of heaven" ran all the way into the sea, but in fact, in the past 30 years after the 1970s, the Yellow River was cut off for many years. Since 1999, the state has implemented unified management and dispatching of the Yellow River, and the Yellow River has been continuously flowing for 20 years. This mother river of the Chinese nation is feeding the people with a brand-new life form, and it also provides a model for the management and protection of rivers in the world and the harmonious coexistence between man and nature.

　　Mother River cut off the river and shouted "thirst" up and down.

　　For thousands of years, the Yellow River has nurtured Chinese sons and daughters like a mother, and has an important strategic position in China’s economic and social development. However, since the 1970s, the Yellow River has been frequently cut off, which not only directly affected the industrial and agricultural production and life in urban and rural areas along the Yellow River, but also further aggravated the river shrinkage, reduced the self-purification capacity of the river and unbalanced the ecosystem, posing a severe test for economic and social development and ecological environment protection.

　　This is a wild goose flying over the Yellow River wetland in Changyuan County, Henan Province on December 25, 2018. Xinhua News Agency reporter Feng Dapeng photo

　　Yuan Dongliang, deputy director of the Hydrology Bureau of the Yellow River Conservancy Commission, said that from 1972 to 1999, the Yellow River was cut off for 22 years, with an average of three times in four years. In 1997, the most serious cut-off occurred so far. The cut-off river extended from the estuary to Kaifeng, Henan Province, with a length of 704 kilometers, accounting for 90% of the total length of the lower reaches of the Yellow River. The cut-off of the Yellow River also caused a series of problems such as river shrinkage, reduction of aquatic life and wetland.

　　Why is the Yellow River, which has been flowing for thousands of years, cut off? For this reason, the Yellow River Water Conservancy Commission set up the project group of "Cause Analysis and Countermeasure Research on the Yellow River Cut-off", and concluded through argumentation and analysis that natural water resources are poor, human water consumption is increasing day by day and scientific management is lacking.

　　This is the winding Yellow River channel (photographed by drone) taken near Zhangzhuang Village, Dongbatou Township, Lankao, Henan Province on June 20, 2018. Xinhua News Agency reporter Feng Dapeng photo

　　Zhou Kangjun, a senior engineer of the Water Resources Management and Dispatching Bureau of the Yellow River Conservancy Commission, said that the Yellow River is located in the arid and semi-arid area of Eurasia, with scarce precipitation and poor water resources. However, with 2% of the country’s water resources, it has undertaken the water supply tasks of 12% of the population, 15% of cultivated land and dozens of large and medium-sized cities. Coupled with the climate impact, the rainfall has decreased, and the agricultural irrigation area and water consumption in the Yellow River basin and downstream irrigation areas have increased rapidly, making the water of the Yellow River poor.

　　Unified regulation of water resources continues to write about the running of rivers

　　Due to the lack of a unified water resources dispatching and management system in the Yellow River in those years, once it encounters a dry year, various places along the river compete for water diversion through water diversion projects, resulting in increasingly serious downstream water cut-off. In 1998, 163 academicians from China Academy of Sciences and China Academy of Engineering jointly issued an appeal to "take action to save the Yellow River".

　　In order to solve the crisis of Yellow River cut-off, with the approval of the State Council, in December, 1998, the Ministry of Water Resources and other departments jointly promulgated and implemented the Measures for the Management of Yellow River Water Dispatching, authorizing the Yellow River Water Conservancy Commission to implement unified water dispatching of the Yellow River, which was the first in seven river basins in China. On March 1, 1999, the Yellow River Conservancy Commission issued the first dispatching instruction, and 10 days later, the lower reaches of the Yellow River resumed flow as planned.

　　In the past 20 years, the chief executive responsibility system has been implemented in the water dispatching of the Yellow River, and the "Measures for the Management of Water Dispatching of the Yellow River" and other laws and regulations have been strictly implemented, and the water resources management system has become increasingly complete; Jointly dispatch the backbone reservoirs of the main branches and tributaries to fully adjust the temporal and spatial distribution of water resources; Improve the Yellow River water resources management system; Explore ways to optimize the allocation of water resources in the Yellow River by market means, and create a precedent for the transfer and transaction of water rights in China.

　　Ke Sujuan, director of the Water Mediation Department of the Yellow River Water Conservancy Commission, said that since the unified dispatching of the Yellow River, there have been eight years of extremely dry water, and the water inflow is lower than that in 1997 and 1995, when the interruption was serious. However, through strengthening the dispatching management, there was no interruption.

　　Through 20 years’ water dispatching, a dispatching management model of "unified water distribution by the state, water distribution by provinces (regions), dual control of total water consumption and cross-section flow, and unified dispatching of important water intakes and key reservoirs" has been formed on the Yellow River. The water dispatching scope of the Yellow River has been extended from some sections of the main stream to the whole main stream and important tributaries, from non-flood season to flood season, and the dispatching goal has also changed from ensuring the continuous flow of the Yellow River to actively striving for the functional continuous flow of the Yellow River, paying more attention to the protection of ecological water use, and the dispatching means have been constantly improved.

　　The river flows smoothly and the water is clear, outlining a new picture of green development

　　The Yellow River has not been cut off for 20 years, which not only provides water resources for urban and rural development along the line, but also becomes an ecological corridor, radiating 750,000 square kilometers of green water and green mountains. The water resources of the Yellow River have become an important guarantee for the "granary of China" and an important support for national energy security. It is also a ballast stone for the economic and social development of the basin and a star for the improvement of the ecological environment.

　　Ke Sujuan said that Inner Mongolia, Henan, Shandong, Hebei and other provinces (regions) in the Yellow River basin and water supply areas are the main grain producing areas in China, while Ningxia, Inner Mongolia, Shanxi, Shaanxi and other places are important energy bases in China. Since the unified dispatching, the rational distribution, scientific dispatching and dynamic management of the Yellow River water resources have met the water demand of the provinces (regions) to the maximum extent.

　　According to statistics, up to now, the cumulative water supply of the main stream has exceeded 600 billion cubic meters. In the case of the "congenital shortage" of water resources in the Yellow River, it has also diverted water from the Yellow River to Tianjin for 7 times, Hebei for 16 times and Qinghai for 20 times, with a total inter-basin water transfer of 21 billion cubic meters, which has provided water source guarantee for human drinking safety, grain harvest and energy security in the river basin and water supply area, nourished the arid and water-deficient northwest China and watered thousands of miles of fields.

　　Wang Huaru, a senior engineer of the Yellow River Water Resources Protection Research Institute, said that the unified regulation of water quantity kept a certain flow in the lower reaches of the Yellow River in non-flood season, leaving "ecological water quantity" for the river itself and repairing the downstream river ecosystem. The open water area of wetlands in the Yellow River Delta Nature Reserve has increased from 15% to 60% now, and the number of birds in the nature reserve has increased to 368. Long-lost migratory fish have reappeared, and the estuary delta ecosystem has reappeared with the vitality of green fields and gulls.

　　In the past 20 years, from frequent water cut-off to smooth flow of rivers, accurate water resources dispatching and management have made the Yellow River cut-off a thing of the past, which fully embodies the ability of China government to manage rivers and provide reference for other rivers in the world to solve water resources problems.

　　China news agency, Beijing, December 10 (Reporter Wang Qingkai) On the 10th, the head of the online transaction supervision and management department of the State Administration of Market Supervision of China told reporters about the newly issued Interim Measures for Handling Complaints and Reports in Market Supervision and Management (hereinafter referred to as the Measures), saying that administrative mediation can be applied to all consumer rights disputes in the field of market supervision, including food, medicines, consumer goods, special equipment and intellectual property rights.

　　The person in charge said that the formulation of the "Measures" is to unify the channels and processing modes of public appeals and improve the efficiency of serving the public; Straighten out and reconstruct the handling mode of complaints and reports, and promote the "chemical integration" of market supervision functions. Complaints about food and drugs can be mediated by the market supervision department.

　　The person in charge believes that the scope of administrative mediation is usually limited to providing relief to the vulnerable groups in the market economy in order to help the market failure. In the field of market supervision, consumers who meet the needs of life can request mediation when they encounter consumer disputes including fair competition, food, medicines, consumer goods, special equipment, prices, intellectual property rights and so on.

　　The data shows that administrative mediation has played an important role in consumer rights relief. In 2018, the national market supervision department recovered economic losses of 3.117 billion yuan for consumers through mediation.

　　It is reported that the Measures have also made some innovations in the administrative mediation system, exploring the entrusted mediation system and the participation mechanism of professionals. The market supervision department may entrust consumer associations or other mediation organizations established according to law to mediate on its behalf.

　　The person in charge particularly emphasized that the Measures clearly stated that the mediation of disputes over consumers’ rights and interests does not exempt operators from other legal responsibilities according to law, and clearly opposes the phenomenon of "substituting punishment with adjustment".

　　The Measures will be implemented on January 1, 2020. It will effectively improve the effectiveness of market supervision departments in serving the public and provide strong support for administrative law enforcement.

　　Cctv newsAccording to the Central Meteorological Observatory, the No.5 typhoon "Du Surui" will move into the northeast of the South China Sea this year, and will land on the coast of Fujian and Guangdong in the morning of the 28th. The intensity of landing is strong typhoon (42-48m/s, 14-15), and it may go deep inland after landing, and its influence scope will be further expanded. "Du Surui" has the characteristics of strong landing intensity, strong wind and rain influence and wide range, and may be the strongest typhoon that landed in southern Fujian since 2017 and the strongest typhoon that affected eastern Guangdong in the past 10 years.

　　Typhoon "Du Surui" intensified into a super typhoon level on the evening of July 24th. At 14: 00 on the 26th, its center was located on the sea about 280 kilometers south of Eguanbi, Taiwan Province, China, and the maximum wind force near the center was 16 (55 m/s, super typhoon level).

　　It is estimated that Du Surui will move to the northwest at a speed of 10-15 kilometers per hour, with little change in intensity. It will move into the northeast of the South China Sea from the night of 26th to the morning of 27th, and land in Fuqing, Fujian to Huilai, Guangdong on the morning of 28th. It is likely to land in Jinjiang, Fujian to the border of Fujian and Guangdong (strong typhoon level, 42-48m/s, 14-15). After landing, it turned to the north, and the intensity gradually weakened, but the typhoon circulation will be maintained and northward for a long time. The Central Meteorological Observatory issued the first typhoon red warning this year at 10: 00 on the 26th.

　　Gale forecast: It is predicted that from 26th to 29th, there will be 6-8 winds and 9-10 gusts in the east of Taiwan Province, eastern and southern South China Sea, bashi channel, Taiwan Province Strait, Taiwan Province Island and its coastal areas, south-central and eastern coastal areas of Fujian, eastern Guangdong, 9-12 winds and 13-15 gusts in the southern coastal areas of Fujian, bashi channel, northeastern South China Sea and south of Taiwan Province Strait, and the typhoon center will pass by.

　　Rainfall forecast: It is estimated that from 26th to 29th, there will be heavy rains in parts of Taiwan Province Island, eastern Zhejiang, Fujian, eastern Guangdong and coastal areas, Jiangxi, Anhui, Huanghuai and North China, with heavy rains in eastern and southern Taiwan Province Island, central and southern Fujian and eastern coastal areas, eastern Zhejiang coastal areas and eastern Guangdong. Among them, the cumulative rainfall in the eastern and southern parts of Taiwan Province Island, south-central Fujian, eastern coastal areas of Zhejiang, eastern Guangdong and other places is 150 ~ 250 mm, local area is 300 ~ 500 mm, and local area in eastern Taiwan Province Island can reach 500 ~ 700 mm; The maximum hourly rainfall in the above areas is 30 ~ 60 mm, and the local rainfall can reach more than 80 mm.

　　Rainfall period: On 26th, the heavy rainfall mainly affected Taiwan Province Island and the coastal areas of Zhejiang, from 27th to 28th, it affected Zhejiang, Fujian, Guangdong and Jiangxi, and on 29th, it continued to affect Anhui, Huanghuai and North China.

　　In addition, from 26th to 28th, due to the typhoon’s long-distance influence, moderate to heavy rain will also occur in parts of the eastern part of southwest China, the eastern part of northwest China, North China, Huanghuai and other places, with local heavy rain to heavy rain.

　　It is estimated that from July 26th to 29th, there will be medium and high risk of typhoon disasters in southern Taiwan Province Island, Fujian, eastern Guangdong, southeastern Zhejiang and eastern Jiangxi. Among them, southern and northeastern Fujian, eastern Guangdong, southeastern Zhejiang and other places are prone to flash floods and geological disasters, and small and medium-sized rivers in southern Fujian and eastern Guangdong have meteorological risks of exceeding warning or exceeding guaranteed water levels; The southern part of Taiwan Province Island, the south-central and eastern parts of Fujian, the eastern part of Guangdong and some sea areas in the southeast of China are at risk of gale disaster.

　　Meteorologists have warned that "Du Surui" has a strong wind and rain intensity, which may cause serious disasters and bring large-scale rainfall to the inland north. The public in Taiwan Province, Fujian, Guangdong, Zhejiang, Jiangxi and other places need to do a good job in typhoon prevention. The public in Anhui, Huanghuai, North China, the eastern part of Southwest China and the eastern part of Northwest China should pay attention to prevent secondary disasters that may be caused by local heavy rainfall.

Since the winter of last year, affected by many factors, such as abnormal climate, the global animal avian influenza epidemic has been on the rise, affecting nearly 40 countries and regions in Asia, Europe and the Middle East. Our reporter learned from the National Health and Family Planning Commission that the number of cases of H7N9 epidemic (human avian influenza) in China has increased, and most of them are distributed in the Yangtze River Delta and Pearl River Delta regions. Contact with infected poultry or exposure to the live poultry market is an important risk factor for human infection. There is evidence that the virus can’t spread widely among people. From February 6 to 12, 2017, 69 cases of H7N9 were reported nationwide, with 8 deaths. At present, the number of new cases is on the decline. Experts predict that there will still be sporadic case reports in mainland China in the near future. Regarding H7N9, the National Health and Family Planning Commission summarized the following knowledge points:

1. What is the H7N9 epidemic?

The H7N9 epidemic is caused by H7N9 virus. Since the first case of human infection with H7N9 was discovered in East China in 2013, seasonal epidemics have occurred in winter and spring every year.

2. What are the main clinical manifestations of 2.H7N9 cases?

The incubation period is usually less than 7 days, or as long as 10 days. Pneumonia is the main clinical manifestation. Patients often have fever, cough and expectoration, which may be accompanied by symptoms such as headache, muscle aches, diarrhea or vomiting. Severe patients’ condition develops rapidly, and severe pneumonia occurs in 3~7 days after onset. Most of them have a temperature above 39℃, and they have difficulty breathing, which may be accompanied by hemoptysis and phlegm. It often progresses rapidly to acute respiratory distress syndrome, septic shock and multiple organ dysfunction syndrome. A small number of patients can be mild, only showing symptoms of fever with upper respiratory tract infection. The early onset of H7N9 cases has no specific manifestations, and it is difficult to diagnose and treat early. The treatment effect of severe cases in the later stage is poor and the mortality rate is high. At present, the overall mortality rate of reported cases is about 40%.

3. How does the 3.H7N9 virus spread?

The most important risk factor for human infection with H7N9 virus is direct or indirect exposure to the environment polluted by infected live birds or infected birds. There is no evidence that H7N9 virus can be transmitted to humans through properly handled poultry or eggs. In addition, eating cooked food will not infect H7N9 virus. There is no evidence that H7N9 virus can continue to be "human-to-human".

4. Who are the high-risk people infected with H7N9 virus?

Mainly retirees, housework and unemployed people, rural people; Mostly middle-aged and elderly people; Most cases have basic diseases; The vast majority of cases had contact with live poultry before onset or had been to markets where live poultry were sold. People engaged in non-scale and non-standardized poultry breeding, selling and slaughtering have more opportunities to be exposed to infected poultry, and the risk of infection is higher.

5. Is there a vaccine to prevent the disease? Can seasonal influenza vaccine prevent H7N9?

There is currently no vaccine available to prevent H7N9 virus infection. Seasonal influenza vaccine does not prevent H7N9 influenza.

6. How can we reduce the occurrence of severe cases and deaths of H7N9?

The use of antiviral drugs, such as oseltamivir phosphate (Tamiflu), has the best effect as soon as possible after onset. The clinic of comprehensive patients by medical staff

Bed manifestations and suspicious exposure history, suspected of being infected with H7N9 virus, antiviral drugs should be used as soon as possible, without waiting for the results of pathogen detection, so as to reduce the possibility of patients progressing to severe disease.

7. Will the epidemic get worse?

According to the epidemic law in the past, the number of cases will decrease obviously after the Spring Festival every year, and it will be at a low level until the end of April. At present, the upward trend of the epidemic has been contained.

8. Can poultry be eaten at present?

Birds such as chickens and ducks can be bought and eaten, but they must be eaten safely. First, we should pay attention to avoid direct purchase of live birds, direct contact with live birds and self-slaughter of live birds; Second, don’t buy live birds from mobile vendors; The third is to remind the elderly, especially those with basic diseases and poor physical fitness, to avoid or reduce contact with live birds as much as possible.

9. What preventive suggestions do experts have?

Try to avoid contact with live birds, let alone dead birds, and do personal protection. You can choose to buy chilled and chilled poultry products. Pay attention to separate raw and cooked food when cooking, and cook it thoroughly. If you have symptoms such as fever, headache, stuffy nose, cough and general malaise, you should wear a mask, see a doctor as soon as possible, and take the initiative to tell the doctor whether you have been in contact with poultry. Maintain a healthy lifestyle. ▲

The new version of Huan has been pre-sold, and the price covers 298,000-338,000 yuan (only the MAX version). After the upgrade, the pre-sale price of these four cars has increased by nearly 10,000 yuan compared with the current models.

Yu Chengdong’s vote on the upgrade of the new M7 in Weibo before suggested some upgrade directions of this car, mainly four, including exterior interior, intelligent driving ability, driving experience and comfortable configuration. Translated, the appearance of the interior is slightly changed, and the big mouth becomes smaller, and the new color scheme is probably introduced as well; Comfortable configuration should be a high probability to give a better, comfortable and easy-to-use seat configuration.

Are these two the key points? Obviously not, the focus is on intelligent driving ability and driving experience.

These two upgrade points include the ADS advanced suit of 192-line laser radar, which is added to the new M7. Instead of the basic version of ADS that has no lidar scheme, supports high-speed NOA function and has no NOA function in urban areas. The remaining change in driving experience is a CDC suspension system (there is no choice for the old models). However, if it is changed, it is limited to the MAX version, and there is no change to the PLUS version.

Then, what improvements will this car have in theory after the new configuration upgrade?

Advanced edition, can you have high expectations?

Basically, one of the things that we want to do from the launch of the new model from the customer M5 to the customer M7 is to give more models intelligent driving functions or higher-level intelligent driving hardware, and we have made two different choices on the customer M5 and the customer M7 respectively. After the cost of lidar is lowered, more models will be equipped with ADS (with hardware differences).

Look at the sensor level first. What’s the difference?

The advanced version of ADS to be used on the M7 uses a higher-cost 192-line laser radar, followed by a millimeter-wave radar and an ultrasonic radar, which cooperate with a high-definition camera to complete the 360-degree perception of the environment without dead ends. Specifically, it can be equipped with 3 millimeter-wave radars, 12 ultrasonic radars and 10 visual high-definition cameras, and this scheme has been applied in the world.

Besides the other sensors mentioned above, the ADS scheme of 192-line lidar can detect and identify objects in the environment more accurately, especially in irregular objects, abnormal weather perception, close cut, tunnels and other scenes. Lidar has great advantages (previously it was 126-line lidar).

1. In the previous 126-line lidar, the transmitter can only send out 126 laser lines for scanning, while the 192-line lidar can send out 192 laser lines. More laser lines mean that the 192-line lidar can obtain more data points in the same scanning area, thus improving the resolution and accuracy of environmental perception.
2. Then, compared with the 126-line lidar, the detection distance of the 192-line lidar is obviously improved. The 192-line lidar used in the world has the recognition ability of 250 meters, while the detection distance of the 126-line lidar used before is only 150 meters.

Therefore, there is a clear gap between the two versions in perception. To improve under two working conditions, first of all, the feeling of using high-speed NOA will be improved obviously. I have experienced the ability of 192-line laser radar under high-speed NOA working conditions before, and the performance is very stable, especially in the details of parallel operation and car following. At the same time, on the NOA in the urban area, after the laser radar with high beam, it will also have a better perception of the details on the street, which will contribute to the smoothness and stability of the vehicle. After changing the 192-line laser radar, it can be understood that the intelligent driving level is in line with the M9.

Then, will the chip improve its computing power?

On the M7 equipped with lidar, the MDC 610 chip scheme is used, with the maximum computing power of 200TOPS, which can cope with the two functions of high-speed and NOA in urban areas. Now, after upgrading the performance of lidar, the MDC 610 chip scheme with a maximum of 200TOPS is still sufficient. Theoretically, it is possible to copy the set of algorithms of the bound M9 and get on the bus.

In this way, it will improve the performance of the whole set of intelligent driving. For example, the operation of complex instructions under NOA conditions in urban areas may be easier to handle. Before, the NOA function in the M7 urban area we experienced, although it can be done stably, has the style of "old driver", and it is necessary to admit these advantages that it is also comfortable to experience the parallel line and the up and down ramps. However, after replacing the laser radar with a high beam, whether it will make a better experience (or an experience similar to that of the M9) on the function of NOA in urban areas without adjusting the computing power needs further real vehicle tests to get a clear result.

What can I get for using CDC suspension?

At present, the M7 still uses FSD variable damping suspension, but does not use CDC active damping suspension, which is really a big impact on this level of household SUV, especially on the comfort in the car. Then, on this new M7, this suspension system will come standard.

Now, in the same price or level, there are more and more home SUVs with CDC active shock absorption suspension as standard. The ideal L series should be the ultimate configuration, almost all of which are standard. Therefore, it is reasonable and necessary for the new M7 to take this configuration as a main upgrade direction.

The FSD suspension, which is still in use in cash, is only to reduce the cost at the beginning.

To talk about the advantages of this FSD variable damping suspension, firstly, it does not need complex sensors and control systems, and its structure is relatively simple and the cost is low; Secondly, the damping can be adjusted adaptively, which can improve the comfort of some cars. Then, after replacing the CDC active damping suspension, based on the FSD suspension, the CDC suspension can collect data in real time through sensors and actively adjust the damping, which means that it can control the body posture more accurately and provide a more stable driving experience.

Moreover, its response speed is faster, because it can be adjusted immediately according to the real-time road condition data, reducing the roll and pitch angle of the car body, and the lifting effect will be very obvious for a large-sized car like SUV. To put it simply, there are more adjustable parameters, the reaction speed is faster, and the ride feeling is better when it is finally transmitted to the car. Of course, the final adjustment style is definitely a comfortable style, after all, it has to cater to household needs.

Is it possible to have air suspension after adding CDC suspension?

CDC+ suspension, this combination can be used together, for example, it is this configuration on the M9. However, it is very unlikely that the new M7 configuration will appear at the same time.

It is not difficult to realize technically. The space of the chassis should be able to accommodate the combination of CDC+ suspension, but the cost of the model may be difficult to realize. The price of a set of air suspension for M9 is about 10,000 yuan. A product of 400,000 class can support this cost, but it is difficult to support this price for a model that is sold within 250,000. Therefore, don’t think about the suspension for the time being. With CDC suspension, the whole driving quality has been improved obviously.

The last point is about the size of the battery pack.

Personally, I feel that I may add another 2kWh battery pack like the M5 to improve the pure electricity and comprehensive endurance of this car. However, in this case, the possibility of price change of this car is even smaller. After all, the increase of 2kWh battery capacity also means the increase of cost, plus the basic version of the ADS scheme and the CDC suspension.

Therefore, it is highly probable that the change of this new model M7 focuses on the application of the new intelligent driving scheme suite, the improvement of car comfort, and the possible fine-tuning of battery pack specifications (but it may be reasonable not to expand the capacity due to cost considerations).

1905 movie network news The film was released today, featuring powerful actors Dong Liu Hu, Cheng Yuanyuan, Li Zixiong, Ai Liya, etc., and presenting the current entrepreneurial story to the audience. The seven highlights of the film, from the theme, lineup and quality to the social significance conveyed by the film, comprehensively analyze the arduous road of starting a business in Wechat business.

Aspect 1: Focusing on the theme of Wechat business’s entrepreneurial story for the first time is expected.

The first cinema film "Big Wechat business" focusing on the theme of Wechat business tells the story of Liang Tian, an entrepreneurial youth, who is determined to forge ahead and transform from e-commerce to Wechat business through self-employment. From the perspective of ordinary entrepreneurs, the film interprets Eliza’s unusual entrepreneurial experience and shows the growth trajectory of Wechat business’s individuals in a panoramic view. After several ups and downs, Eliza still adhered to his faith and the principle of doing business in good faith, personally guided Wechat business entrepreneurs to establish a correct outlook on life and values, inspired Wechat business groups to make progress and bravely pursue their dreams, and paid tribute to the strugglers in the new era.

Aspect 2: mass entrepreneurship and innovation "entrepreneurship" has become a hot spot on the screen.

After the reform and opening up, the Internet industry in China has developed rapidly and has far-reaching influence. With the advent of the era of national entrepreneurship, the theme of entrepreneurship has also become the darling of film and television creation. Wechat business chose Wechat business as the breakthrough point, and used focus plane to show the arduous road of starting a business from the real economy to e-commerce and then transforming Wechat business. It can not only reflect the changing reality of e-commerce entrepreneurship, but also respond to the call of the times of "mass entrepreneurship and innovation".

Aspect 3: Old drama bones Li Zixiong and Ai Liya joined in to help "Great Wechat business"

In "Big Wechat business", Li Zixiong plays Eliza’s "Bole" boss. Ai Liya, a veteran actor, plays Eliza’s mother-in-law. In the filming process, the two opera bones not only set high standards for themselves, but also "preached and dispelled doubts" for the young actors in the group and shared valuable experiences. It is expected that a group of powerful actors will compete on the same stage.

Li Zixiong has created many classic characters, such as "Big Brother Cheng" and "Xi Rong". At the age of 27, he won the Best New Actor Award at the Hong Kong Film Awards for "The True Color of Heroes" and became one of the representatives of classic Hong Kong film villains. He has also been nominated for the Best Supporting Actor Award at the Hong Kong Film Awards and the Best Supporting Actor Award at the Taiwan Golden Horse Awards. In The Great Wechat business, Li Zixiong took off the label of "villain" and became a good boss of China, which was a surprise.

Ai Liya, the winner of the Golden Rooster Award and the China Watch Award, has successfully portrayed the roles of Bai Yufen in "The Big House Gate" and Mrs. Lou in "The Punisher of the Great Song Dynasty". I believe that the addition of Lao Xigu will add color to the film.

　

Aspect 4: Powerful actors Dong Liu Hu and Cheng Yuanyuan show empathy.

In the film "Big Wechat business", Dong Liu Hu plays Eliza, an entrepreneurial youth, and Cheng Yuanyuan plays Meng Rou, Eliza’s wife. She is a supporter of Eliza’s cause and a guide.

Dong Liu Hu, a powerful actor, was deeply loved by the audience for his roles in the self-made solo drama "Ugly Woman Invincible" by Hunan Satellite TV and the dynasty in "Young Bao Qingtian II". Eliza, the male actor in this film, is a promising young man. Determined to make progress, he wholeheartedly led the villagers to get rich together and finally realized his dream. Cheng Yuanyuan, an acting actor, was nominated as the best actor in Changchun International Film Festival for her role of Gu Qianqian in the new version of A Dream of Red Mansions. This time, their joint performance of the movie "Big Wechat business" has attracted a lot of discussion and attention.

Aspect 5: A team of thousands of people waded through the mountains just to restore the most authentic Wechat business.

The film "Big Wechat business" was filmed and produced by Hunan Film Channel, and the behind-the-scenes team crossed four provinces of Hunan, Jiangxi, Guangdong and Guangxi, trekking 5,000 kilometers. The 95-minute film works include the hard work of the creative team, including more than 120 professional photographers and 976 group performers, day and night. The attitude of striving for perfection behind filming is the basic attitude of entrepreneurs in this era and the attitude of every micro-businessman. Just like the theme expressed in the film, the industrious spirit of contemporary entrepreneurs, which is the same day and night, will deeply impress the audience.

Aspect 6: Wechat business’s inclusion in the e-commerce law "Greater Wechat business" responds to the call of the times

With the implementation of the "Electronic Commerce Law of the People’s Republic of China" on January 1st this year, more and more people began to pay attention to the industries in Wechat business. The film "Big Wechat business" was released under such an opportunity, which not only showed the audience the micro-businessmen with positive energy values, but also set a benchmark for young entrepreneurs in combination with the background of the implementation of national legislation, tore off the label of "three noes" for Wechat business, and made the rights and interests of consumers more secure. As the film’s release approaches, it is believed that it will surely lead Wechat business forward, encourage entrepreneurs to pursue their dreams bravely, and lead every ordinary person to contribute to the realization of the Chinese dream.

Aspect 7: "Great Wechat business" triggered a heated discussion in society to promote the positive energy of the Chinese dream "We are all dream catchers"

In the tide of the times when the country advocates "mass entrepreneurship and innovation", countless ordinary people realize their own values and spiritual pursuits through Wechat business’s entrepreneurship. As soon as The Great Wechat business was released, it triggered a heated discussion in the society, presenting the audience with the real road to entrepreneurship of contemporary youth through a unique perspective. The positive energy values exported by the film will also lead Wechat business to keep advancing, encourage entrepreneurs to bravely pursue their dreams, and become a bright light to illuminate young entrepreneurs. As Eliza said in the film: "We have the responsibility to make the 50 million micro-businessmen have a more sense of mission and positive energy, and realize our Chinese dream together."

The movie "Big Wechat business" has landed in the national cinema today.

Since its launch last month, Zhiji LS6 has gained extensive attention in the industry due to its leading edge in high-end intelligence. On October 20th, we were fortunate to test drive this peak masterpiece in Nanjing Ginkgo Lake Park. This Zhiji LS6 "smart driving" experience can be described as textbook level. With the blessing of Zhiji’s "Future Smart Cabin" series of leading intelligent technologies, Zhiji LS6 focuses on the pain points of urban commuting scenes to create "Super Smart Driving 6th Space". With unprecedented immersive scene-based intelligent test driving space and tailor-made challenges, we set up "smarter ‘6’ AI smart driving maze experience area", "high-performance ‘6’ performance driving control experience area", and in-depth experience of Zhiji LS6 "Future Smart Cabin", "Quasi-900V Super Performance Platform" and "International Fan Design".

The most intelligent test drive in history

At a time when traditional SUV performance tests are cookie-cutter, how can the test drive activities be innovative? As the "strongest 6 series in history", for the Zhiji LS6, the performance test is only the basic operation, and the intelligent peak experience is the core competitiveness of the Zhiji LS6.

In order to deeply experience the high-level intelligence of Zhiji LS6, Zhiji LS6 has created a super smart driving sixth space, pioneered the new gameplay of "AI smart driving maze", simulated the typical road conditions, traffic and people flow in big cities, and deeply experienced the future smart cabin in the commuter meta-universe. It has the ultimate performance experience and comprehensive driving control experience. It comprehensively tests the strength of the "strongest 6 series in history" and sets the industry benchmark with the "most intelligent and fun test drive in history". People have to be amazed by the all-round caring ability of this future smart cabin.

The big screen can understand

Can you imagine that a car can still drive normally when the front and rear glass, windows and rearview mirrors are all black? The Zhiji LS6 easily passes the test in the "Ultimate Blindfold Challenge" in the dynamic test drive. With the blessing of the "Global Digital Vision Blindfold" function, the Zhiji LS6 can easily pass in narrow and complex road conditions in the state of full blindness, with the powerful assistance of Zhiji’s original global digital vision blinding and traditional 360 panoramic images.

When you are driving in the city streets and encounter sudden heavy rain, don’t worry, the rainy night mode of Zhiji LS6 is ready to escort you in the scene of extremely poor visibility. Whether it is the safety blind spot or the fog blocking of the rearview mirror, you can use Zhiji’s global digital vision to make up for the blindness, as if one eye is lit in the dark, so that you can drive with confidence and boldness.

Super practical one-click AI driving

In the dynamic test drive, complex parking spaces, narrow alleys and other areas were set up on the test drive site to comprehensively test the practicality of Zhiji LS6’s one-button parking, one-button escape, one-button welt, and one-button tracking functions.

When you drive into a congested street, the only parking space is narrow, and the distance between the front and rear cars is limited, it can’t help but make people feel anxious. At this time, Zhiji LS6 is the best intimate little assistant. The functions of "one-click parking" and "one-click escape" can let you relax your hands, feet and mood, and leave all the problems to it to complete. When you accidentally get into a dead end and can’t turn around, "one-click tracking" will let you no longer worry. Zhiji LS6 has the strongest brain and can automatically remember the path of 50m distance, take you out of trouble smoothly, and return to the spacious and safe road surface to continue flying.

How about it, this is the absolute advantage of Zhiji LS6! When many new energy manufacturers are still thinking about "what a really easy-to-use smart car should look like in the state of human-machine co-driving", Zhiji LS6 has taken the lead in proofing – with "serving the driver" as the core, through intelligent technologies such as global digital vision blinding and one-click AI driving, it not only easily solves the road’s right-turn blind spot to rush out of electric vehicles, blurred rearview mirrors on rainy nights, stickers that are too difficult to worry about scratching, and narrow parking spaces that cannot be driven out. "Open the eyes of the left hand, and get the last meter of the road with the right hand", but also bring fresh and interesting AI interactive experiences such as SHUA and Zhiji generative large models. No matter the present or the future, the LS6 will be a smart car that is easy to use, easy to drive, fun, and worth closing your eyes to.

　　CCTV News:According to the website of the Ministry of Environmental Protection, in order to improve the quality of urban atmospheric environment, the Ministry of Environmental Protection recently issued the Catalogue of Highly Polluted Fuels (hereinafter referred to as the Catalogue) in accordance with the provisions of Article 38 of the Law on the Prevention and Control of Air Pollution in People’s Republic of China (PRC), which was revised and passed by the National People’s Congress Standing Committee (NPCSC) on August 29th, 2015.

　　According to the Catalogue, the fuels referred to in the catalogue are fuels that need to be strengthened according to factors such as product quality, combustion mode and environmental impact. The catalogue stipulates conventional fuels such as coal and its products (including raw coal, loose coal, coal gangue, slime, coal water slurry, briquette, coke, blue charcoal, etc.) and oil used in production and life. Industrial waste and garbage, agricultural and forestry residues, charcoal used in catering industry and other auxiliary fuels are not within the scope of catalogue control.

　　The Catalogue makes it clear that according to the strict degree of control, the fuel combinations prohibited from burning in the no-burn zone are divided into Class I (general), Class II (strict) and Class III (strict). For petroleum coke, oil shale, crude oil, heavy oil, residual oil and coal tar, due to their serious pollution to the urban atmospheric environment after direct combustion, Class I, Class II and Class ш in the catalogue are all included in the control scope. For coal and its products, considering that coal is still the main energy consumption in China’s cities at present, coal and its products are divided into three categories with different degrees of strictness for control. For biomass briquette, the burning mode of biomass briquette is regulated only under the strictest control requirements of class ш, that is, it must be burned in a special boiler for biomass briquette equipped with high-efficiency dust removal facilities such as bag filter.

　　The Catalogue emphasizes that according to the Law on the Prevention and Control of Air Pollution, the catalogue of highly polluting fuels is determined by the competent department of environmental protection in the State Council. This catalogue is only applicable to the management of the no-burn zone of highly polluting fuels designated by the urban people’s government according to law, and it is not used as the no-burn management or other management basis for fuels outside the no-burn zone.

　　The Catalogue requires that the people’s government of a city, according to the requirements for improving the quality of the atmospheric environment, the energy consumption structure and the economic affordability, demarcate the no-burn zone in the urban area in the principle of seeking truth from facts, and choose one of them according to local conditions, so as to make steady progress according to its capabilities. In the management of the no-burn zone, the people’s government of the city should give full play to the role of the catalogue, start with improving the urban energy structure, and vigorously promote the production and use of clean energy. And gradually expand the area of the no-burn zone when conditions permit.

　　In the next step, the Ministry of Environmental Protection will guide cities to do a good job in revising and formulating the delineation and management regulations of high-pollution fuel no-burn zones, and give full play to the role of the Catalogue in improving the quality of urban atmospheric environment.

　　Cctv newsAccording to the website of National Health Commission, in order to further improve the nucleic acid detection in Covid-19 and gain precious time for epidemic prevention and control, on the basis of the current 5-in-1 and 10-in-1 mixed sampling detection, the medical rescue team of the joint prevention and control mechanism in the State Council actively organized professional institutions and experts to demonstrate and study and put forward technical methods to further improve the efficiency of nucleic acid detection. After the verification of real clinical samples, on the basis of ensuring the quality of nucleic acid detection, we decided to steadily implement the 20-in-1 mixed sampling detection technology, and organized and formulated the Technical Specification for 20-in-1 Mixed Sampling Detection of Nucleic Acid in Covid-19 (hereinafter referred to as the "Specification").

　　20-in-1 mixed sampling detection can greatly improve the detection efficiency and is more suitable for large-scale population nucleic acid screening. Compared with the 10-in-1 mixed mining detection technology, the adjustment is mainly made in the sampling tube. The Code is divided into 10 parts, mainly including: specifications of sample collection consumables, requirements of collection location, collection process, specimen submission, laboratory reception, specimen detection and quality control, treatment of test results, sample treatment after testing, basic requirements of technicians, biological safety protection, etc.

　　Attached to the Covid-19 nucleic acid 20-in-1 mixed sampling detection technical specification:

　　In order to guide all localities to carry out mixed sampling detection in Covid-19, and further improve the ability and efficiency of nucleic acid detection, based on the existing 10-in-1 mixed sampling detection technology, this specification is formulated for Covid-19 20-in-1 mixed sampling detection technology (which refers to the method of collecting 20 swabs collected from 20 people in one collection tube for nucleic acid detection).

　　First, the sample collection consumables specifications

　　(a) virus collection tube. The pipe cap and pipe body should be made of polypropylene, and the spiral mouth can be sealed with moderate tightness. The tube is transparent and has good visibility. The height of the collection tube (including the tube cap) is (100 5) mm, the capacity is calibrated by the enterprise to be 20-30ml, and it contains 11-12mL of preservation solution of guanidine salt or other effective virus inactivators. The preservation solution should have a color (such as pink) that is easy to observe and identify, and maintain a certain fluidity to facilitate sampling.

　　(2) Collecting swabs. It is advisable to use non-cotton and non-calcium alginate swabs such as polyester and nylon, and the handle is made of non-wood materials. The breaking point is located about 3cm from the top of the swab head, which is easy to break.

　　 Second, the collection site requirements

　　 Choose an open and well-ventilated site as a centralized collection place for large-scale crowd screening. According to the original site conditions, it is divided into waiting area, collection area, buffer area and temporary isolation area, effectively dispersing the density of people to be inspected. First aid equipment should be set aside.

　　(1) Waiting area. Set up a pedestrian passage and a one-meter line at the same time to ensure the protection and safety of waiting people. According to the weather conditions, it is equipped with facilities such as heat preservation, cooling, sun protection and rain protection. The elderly, children, pregnant women and other people with mobility difficulties are given priority.

　　(2) Collection area. According to the climatic conditions, tents, cold/warm fans and appropriate tables and chairs are provided to ensure that medical staff can work in a relatively comfortable environment. Equipped with disinfection supplies, swabs and virus collection tubes for collection, and paper towels, vomit bags and masks should be prepared for the inspected personnel for later use. If the specimen cannot be transported to the laboratory in time, a 4℃ refrigerator or low-temperature storage box should be prepared for temporary storage. Emergency plans should be made to prevent the spread and infection of pathogenic microorganisms.

　　(3) buffer zone. The space should be relatively closed, so that the collectors can change their personal protective equipment, and put protective articles, disinfection articles for collection, swabs, collection tubes and outdoor disinfection equipment that match the size of the sampling point.

　　(4) Temporary isolation zone. Used to temporarily isolate suspected patients or high-risk groups found in the collection process.

　　 Third, the collection process

　　(1) Identification and information registration.

　　 1. Registration process. Before collection, the staff assigned 20 patients as a group, and collected and registered relevant information of patients (including name, gender, ID number, contact telephone number, collection place, collection date and time) before collection, and numbered the collection tubes according to the group. Because there are relatively more than 20 people, in order to avoid confusion between different groups of people, when sampling, the next group of waiting people can be strictly separated from the group of people being collected by 2 meters, and the next group of people can enter the sampling area in an orderly manner after this group of people is collected.

　　 2. Registration requirements. It is recommended to use information means such as ID card reader and two-dimensional bar code to associate the information of the client, so as to improve the efficiency and accuracy of information reading.

　　(2) collection methods. The collected person’s head is slightly tilted, his mouth is wide open, and he makes an "ah" sound, exposing the pharyngeal tonsils on both sides. The collector will put the swab over the base of the collected person’s tongue, wipe it back and forth at least three times with a little force on both sides of the pharyngeal tonsils, and then wipe it up and down the posterior pharyngeal wall at least three times. After the operation, put the swab head into the tube, place the swab breaking point at the nozzle, break it slightly to make the swab head fall into the liquid of the collection tube, discard the broken swab rod, tighten the tube cover, and put the collection tube on a stable shelf. After each case is collected, the collector should carry out hand disinfection.

　　(3) mixed swab. Collect the remaining 19 swabs in turn according to the above collection method, and put the collected swabs into the same collection tube with gentle movements to avoid aerosol generation. After continuously collecting 20 swabs, tighten the tube cover to prevent spillage. Note that the throat swab should be immersed in the preservation solution. If there are less than 20 swabs in the collection tube, special marks should be made and recorded.

　　 Fourth, the specimen inspection

　　(1) Check the information. Check the information on the label of the collection tube and the mixed mining registration form to ensure accuracy, completeness and consistent numbering.

　　(2) Specimen placement requirements. Put the checked collection tube into a transparent plastic sealed bag (one-layer container) and seal the mouth of the bag, and spray the outside of the sealed bag with 75% ethanol. Put the sealed bag into a two-layer container (optional packaging box with proper amount of hygroscopic material or double-layer medical garbage bag), and spray 75% ethanol for disinfection after sealing. Put the container on the second floor into a special specimen transfer box marked with "biological hazard" (it is recommended to use a transfer box that meets the UN2814 standard for the transportation of Class A goods in the Technical Rules for the Safe Transportation of Dangerous Goods by Air), and a cooling gel ice pack should be placed between the container on the second floor and the transfer box. The container on the second floor should be fixed in the transfer box to keep the specimen upright. After sealing the transfer box, 75% ethanol was sprayed for disinfection, and the surface of the transfer box was clean and pollution-free.

　　(3) Specimen transport requirements. The standard transfer box shall be transported by special specimen transport personnel. Specimens should be sent to the laboratory within 2-4 hours after collection. If it cannot be sent for inspection immediately, it shall be equipped with a special refrigerator or freezer for preservation, and the specimens shall be registered for receipt and preservation. Specimens can be stored at 4℃ within 24 hours after collection.

　　 V. Laboratory reception

　　(1) Specimen receipt. The delivery and receiving personnel shall double sign for the specimen. The receiver shall check whether the transfer box and the container on the second floor are damaged.

　　(2) the specimen is opened. The transfer box should be opened in the core area of the biosafety level II laboratory and the second-floor container should be taken out. Open the container on the second floor in the biosafety cabinet, spray or wipe it with 75% ethanol for disinfection, take out the sealed bag, spray or wipe it with 75% ethanol reagent for disinfection, and check whether it is sealed well.

　　(3) specimen inspection. Take out the collection tube, check whether the tube wall is damaged, the nozzle leaks, etc., and spray or wipe with 75% ethanol for disinfection after confirming that there is no damage or leakage. If there is any damage or leakage, the operation should be stopped immediately, covered with absorbent paper and disinfected with 0.55% chlorine-containing disinfectant, and destroyed after unqualified registration.

　　(4) specimen preservation. Specimens that cannot be detected in time are stored in a special refrigerator. Samples detected within 24 hours can be stored at 4℃. Specimens that cannot be detected within 24 hours should be stored at -70℃ or below. If there is no storage condition at -70℃, it will be temporarily stored at -20℃. Avoid repeated freezing and thawing of specimens. Set up a special library or counter to save specimens, and manage them with double locks.

　　(5) The transshipment container is removed. The inner and outer walls of the used second-floor container were wiped and disinfected with 75% ethanol, and then moved out of the biosafety cabinet. After the experiment, ultraviolet lamps were used for disinfection.

　　 Six, specimen detection and quality control

　　In accordance with the "Covid-19 nucleic acid detection manual of medical institutions (Trial Second Edition)" related requirements.

　　 Seven, inspection results processing

　　 Covid-19 nucleic acid qualitative test report shall include test results (detected/positive, undetected/negative), methodology, detection limit, etc.

　　(1) Judgment of results. According to the instructions of the amplification reagents used, it is judged that the detection result is undetected/negative or detected/positive.

　　(2) Review of positive results.

　　 1. If the mixed sampling test result is positive, gray area or single target is positive, notify the relevant departments to temporarily isolate the 20 subjects of the mixed sampling tube separately, and re-collect the single tube swab for review.

　　 2. If the single-tube nucleic acid test is negative, it will be returned according to the negative result. The temporary isolation personnel shall be released immediately; If the test result is positive, report it according to the procedure.

　　 Eight, sample processing after detection
