Jiangsu Dafeng tornado has caused 2 deaths and 15 injuries! Revealing which areas of China tornadoes love to "punch in", Guangdong actually ranks second in the country.

At about 16: 00 on August 13th, tornadoes occurred in Wanying, Xiaohai and Nanyang towns in Dafeng District, Yancheng City, Jiangsu Province, which were preliminarily identified as EF2 medium-intensity tornadoes by experts. According to a report on the evening of 13th in Dafeng District, Yancheng City, Jiangsu Province, 2 people were killed and 15 injured in the disaster.

Tornado is called the king of style. There are many rumors about its powerful power, such as uprooting trees, blowing cars into the sky, and turning into dragons to absorb water … Are these rumors true or false? How strong is the EF2 tornado? Why are tornadoes frequent in Jiangsu? China Weather Network launched the tornado chapter of "Weather Archives", and let’s listen to its confession.

Hello, everyone, I am a tornado. My name is world-famous, but not many people have actually seen me. Because of this, there are many legends about me circulating in the Jianghu. There are people who drive around the world to track my figure in order to see my style. Next, I will introduce myself: first of all, please remember, don’t be infatuated with me, I am just a gust of wind, a wind that can kill people.

I was born in unstable weather conditions, which is a strong and small-scale air vortex caused by air convection. When cold and warm air masses collide with each other, a cumulonimbus cloud will be formed. There are high-altitude airflow and low-altitude airflow inside the huge cumulonimbus cloud. When the ascending airflow is constantly entangled with the descending airflow, a strong horizontal vortex will occur. In the process of vortex rotation, it continues to be involved in more airflow, and it keeps growing like a snowball. I was formed when the vortex developed large enough and fell to the ground.

As a member of the strong convection family, my body is petite, with a diameter of several meters to several hundred meters, especially as large as 1 kilometer. My playing time is usually short, usually lasting a few minutes to dozens of minutes. Although I am small, I am extremely destructive. My central wind power can reach 30-150 m/s, and in extreme cases it can reach 300 m/s, which is several times faster than the maximum wind speed in the center of a strong typhoon. The huge wind speed allowed me to pull up trees, destroy houses and roll up cars, and the place I passed was like an explosion scene.

Of course, I don’t always burst like this. My family is divided into different sections. According to the current international EF grade (Fujita series), my strength is divided into six grades from low to high: EF0 to EF5. EF0 and EF1 are the most common. Although they are only bronze sections, they are enough to break the glass and blow the chimney. The EF1 level can overturn the roof, causing casualties.

When my strength reaches EF2 level and above, it belongs to a strong tornado, and EF2 level may cause trees to be uprooted; EF3 class even trains can be blown down; EF4 level can shovel and level houses; EF5 is the king’s position, and the damage is devastating. The house with frame structure may be thrown out together with the foundation, the reinforced concrete structure building will be seriously damaged, and the car may be blown away.

These are definitely not alarmist, and my black history makes people tremble.

For example, the Tri-State Tornado, which happened on March 18th, 1925, is considered as one of the most violent tornadoes in American history. The tornado started from Missouri and went through Illinois and Indiana, moving 350 kilometers in a straight line, causing nearly 700 deaths and 2,000 injuries. Wherever it went, it was a mess. Although the tornado was not officially rated by the United States, it was recognized as EF5 by most experts.

The EF4 tornado that occurred in Shanghai, China on September 24th, 1956 became one of the most famous tornadoes in China, and even appeared in geography and physics examinations. In the afternoon, a violent tornado hit the eastern edge of Shanghai. The strong wind swept a four-story oil storage tank with 110,000 kilograms to a height of 15 meters and threw it 120 meters away. The tornado also blew down a four-story reinforced concrete building in the suburbs, causing serious casualties.

Ever heard of "tornado hunter"? There is such a group of people in America who are dedicated to chasing my figure. Of course, the so-called hunters can’t hurt me at all. At most, they shoot my majestic posture and record the data when I pass by.

Tim samaras, a famous American tornado hunter, has his own chasing team. When a tornado comes, everyone else is hiding, and only their car runs in the opposite direction. Tim is a professional tornado hunter. The car is loaded with meteorological instruments, collecting data such as wind speed and air pressure, and monitoring my movements in real time with radar charts. But on May 31, 2013, when he was tracking a tornado in Oklahoma, the tornado suddenly turned, and Tim was thrown 800 meters away and died. I really hope that Tim’s unexpected death can alert other fans, to fear nature, and not to be too close to me. You can never predict whether you will catch up with me or I will catch up with you in the next second.

As you may have seen, my figure appears all over the world, and it is not easy to catch me if the so-called dragon sees the tail without the head. Scientists have also explored some of my haunting laws through a lot of data research. I mainly hang out in mid-latitude areas, and I visit North America, Europe, Russian, China, Japanese and Australian every year. Among them, the United States is called the "Tornado Kingdom", which is the country I visit the most, with an average of 1,141 punch cards per year (average from 2000 to 2020).

I have left my trail in most parts of central and eastern China, among which I often go to the middle and lower reaches of the Yangtze River. Among my favorite provinces, Jiangsu ranks first, and the northern part of Jiangsu is in the climate transition zone between subtropical and warm temperate zones, which is easy to accumulate unstable energy. In addition, the local topography is low and flat, and rivers and lakes are intertwined, which is conducive to my development and growth.

Guangdong is also a province where I often punch in, especially in western Guangdong, where I often appear with typhoons. When the typhoon landed in western Guangdong, the vertical wind shear was often stronger and the water vapor transport was sufficient, which provided a favorable atmospheric environment for my birth. The terrain here was flat and suitable for my growth. In addition, the conditions in Hubei and Anhui are also good, and I will go there twice a year or so.

My favorite playing time is spring and summer, especially from April to August, in which July is the most, accounting for about 28% of the whole year, followed by April. During the day, I prefer to hang out in the afternoon to the evening, because after the solar radiation during the day, the atmospheric stratification is unstable during this period, which is the most prone period for strong convective weather, including me.

Because of my destructive power and elusive unruly personality, there have been various rumors about me in the Jianghu for many years. Today, I will give you a bottom. Don’t be too shocked. Some rumors are really true.

One day, there was a sudden thunder and lightning and dark clouds on the calm water, and then a water column like a dragon suddenly jumped out and soared into the sky, as if to suck up the water on the ground. The legendary dragon absorbs water, which is actually my appearance above the water surface, also known as waterspout. When the dragon absorbs water, my upper end is connected with thunderstorm clouds, and my lower end extends to the water surface, forming a shocking scene of water and sky connecting.

As for letting the sky rain Yu Yu and frogs, this skill is too simple for me. When the waterspout happens, the strong suction may involve fish, frogs and other animals in the water, and then it will be carried to other places by strong wind, which can cause the wonders of animal rain in your eyes.

Can tornadoes "travel" people? I must have seen too many fairy tales to ask this question, but I still have to answer you seriously. It is possible. There was a record that someone was involved in me and was later found hundreds of meters or kilometers away. However, this so-called "trip" is very scary. People involved will face huge wind speed and air pressure, and they will experience dizziness, suffocation, hypothermia, trauma and even tearing. It is definitely a miracle to survive.

So I’m here to remind you that if you meet me unexpectedly, you must stay away as soon as possible and hide in the basement or a solid building. Don’t just focus on making friends and miss the escape time. It is still the peak season of my appearance, and there will be reports of my presence from time to time in various places, so we must not take it lightly.

Interview with the man in Munich, who turned out to be a blond and blue-eyed fresh meat.

Kirill Zayetsev


Special feature of 1905 film network Like the prototype story that the Soviet basketball team staged a Jedi counterattack and overtook the American team in the last three seconds, the Russian sports film, which was not optimistic, also made a beautiful turnaround in the China mainland film market.


On the day of its premiere on June 13th, "Dead Munich" ranked only a dismal 4.9%, far below 22.6%, and the box office was not satisfactory, ranking only seventh. With the passage of time, the film’s gold-absorbing ability rose instead of falling, relying on word-of-mouth bonus. On the sixth day of release, it successfully overtook and was promoted to the fourth place at the box office in a single day, and the film arrangement also rose day by day. Up to now, "Dead Munich" has captured 65 million box office in China market.


Many famous people in the literary and sports circles, including Jason Wu, Han Han, Zhang Yibai, Michelle Ye, Zhang Bin, Liu Jianhong, Yin Hong, Shi Hang, Zheng Haixia, Xing Aowei, etc., have given this film high praise and greatly appreciated the spirit of struggle embodied in the film. 


The road of counterattack of Munich is still going on, and the "scoring king" of the Soviet basketball team — — Sergei belov’s actor kirill Zayetsev also parachuted into China and recently accepted an exclusive interview with 1905 Film Network.

   

       Dye your hair and grow your beard+carry 30 kg sandbags with your life.

       In order to truly restore Sergei kirill’s exquisiteness of abandoning "small fresh meat"


Beijing is the second stop of kirill’s trip, which is also his first time in China.


Although his trip to China is very tight, he had a close interaction with China audience in Shanghai before, and then he arrived in Beijing the next day, and then he went to Tianjin non-stop. But in him, you can’t see the fatigue of traveling by boat at all, but he is full of energy. Before the interview, he had been humming Russian songs.


When I first met kirill, Xiao Dianjun couldn’t connect him with the calm and cold Sergei in Munich.

"Sergei" in reality


But the most difficult thing is the one-year physical training. "Our shooting is very hard and takes a long time. During the shooting, I have to carry out ultra-high-intensity physical training, which is very difficult for me."

Xiao Dianjun was also impressed by Sergei’s high-intensity training in the movie: when the coach came to persuade Sergei to rest, he found that he couldn’t lift the sandbag of Sergei’s weight-bearing training at all.


How much does that sandbag weigh? Kirill revealed, "At the beginning of filming, the staff restored the props according to the real history, and the sandbags weighed 60 Jin. Although I am training every day, it is too heavy for me and will affect the normal shooting work! " Having said that, kirill smiled shyly. "So in the end, the sandbag I used was 30 kg, and the weight was reduced by half."


In addition to lifelike muscles, kirill also strives to restore the Russian legendary player in appearance. First, kirill dyed a beautiful blonde hair black, and especially "grew" a thick beard.

 

Set photo of "Munich"

Regarding Xiao Dianjun’s question that Sergei didn’t have a beard when the Soviet basketball team won the Olympic champion in Munich, kirill explained: "Sergei really didn’t have a beard in his early years, but then he grew a beard, and the beard became his personal iconic image. In the movie, keeping a beard for Sergei is mainly to increase the artistic effect of the movie. "


Sergei data map

While truly restoring the game process, add a beard to Sergei, and make the coach and players more human by adding emotional lines … … Increasing the artistic effect on the basis of reality is also the core idea of this adaptation of Munich.

       

"Double-faced" actor in drama and film

       Kirill is gentle and wants to talk about a foreign love with China actors in the image.


Kirill Zayetsev starred in Munich for the first time. Before that, he played an unknown Soviet lieutenant in a Latvian film.


Kirill played a Soviet officer in Melanie Chronicle.


Compared with the big screen, kirill is more familiar with the stage of drama. Earlier, he had five years’ experience as a dramatic actor.


"Of course, these are two very different things. On the stage of drama, we always face the real audience. As a dramatic actor, you can get the real feedback from the audience immediately, but in the filming, we just face the camera. Relatively speaking, actors can concentrate more on their performances."


Although kirill admires Sergei’s "sense of responsibility in times of crisis", he is also trying to "draw a clear line" with Sergei — — He defines himself as an actor.


When Xiao Dianjun asked him, "Is he the best basketball player among Russian actors now?" kirill shook his head modestly, "You can’t say that, you can’t say that! I did receive a long time of basketball training before shooting Munich, but now I play less. First of all, I am an actor, and I have played the role of a basketball player. What I need to do most is to finish my job as an actor."

Kirill convincingly completed the interpretation of Sergey. For himself, there are more possibilities in the future.


His next work is a TV series, in which kirill plays an American policeman who comes to Russia from new york.


He said that he also hopes to have the opportunity to participate in China’s films. "I want to try interesting roles and reflect the noble human role in times of crisis."


"I also want to try to talk about a relationship in a China movie."


Perhaps it was the surprised expression on Xiao Dianjun’s face. kirill said happily, "Why Not? (Why not? )”

Highlight the key points of prevention and accurately respond to public opinion

  Core reading

  Not long ago, the General Secretary of the Supreme Leader made important instructions on flood control and disaster relief, requiring relevant departments to accurately guide key areas to do disaster prevention work such as floods in small and medium-sized rivers, dangers in small and medium-sized reservoirs and urban waterlogging, and spare no effort to rescue and provide disaster relief. All localities and departments pay close attention to the floods of small and medium-sized rivers and the safety of small and medium-sized reservoirs, and implement preventive measures to ensure the safety of people’s lives and property.

  At present, China has officially entered the critical period of "seven downs and eight highs" flood control, and many places have entered the main flood season. Since the flood season, China has experienced 18 times of heavy rainfall, and 271 rivers in 21 provinces have experienced floods exceeding the police. The rainy areas are mainly concentrated in the central northeast, the eastern northwest, the southwestern part of North China, the western part of Huanghuai, the eastern part of Jianghuai and the northwestern part of Hubei.

  It is predicted that during the period of "Seven Downs and Eight Ups", there will be more extreme weather and climate events, and regional floods, droughts, high temperature and heat waves will be more important. How to prevent disasters such as floods in small and medium-sized rivers, dangers in small and medium-sized reservoirs and urban waterlogging? How to make up the short board? The reporter conducted an interview.

  Grab early and grab small to deal with floods in small and medium-sized rivers.

  In 4 hours, the rainwater converged from the Simian mountain slope, and the water level of the Qijiang River rose sharply. At the beginning of July, the "No.1 flood of the Qijiang River in 2023" was formed. "The floods in small and medium-sized rivers form quickly and the test is not small." Du Na, director of the Hydrology and Flood and Drought Disaster Prevention Center in Qijiang District of Chongqing, said.

  Forecasts and warnings run ahead, winning the initiative for flood control. "After receiving the weather forecast and the warning of rising water risk in advance, we will transmit the early warning information to 70 villages in the first time. The person in charge of monitoring and early warning and the person in charge of transfer and resettlement will arrive at their posts in time to investigate potential risks and prepare emergency materials in advance. " Duna introduced.

  Chongqing has rugged mountains and developed water systems, and small and medium-sized rivers are the focus of flood control. This year, Chongqing has defined the "four responsible persons" of the people’s government for flood control and flood fighting in 104 mountainous rivers, such as the chief executive, the competent department, the township and village river chiefs, and the patrol and management, and made every effort to ensure flood control safety.

  Small and medium-sized rivers have many points and a wide range. How to prevent floods? "There are about 10,000 small and medium-sized rivers in China. These rivers have small areas, fast confluence and sudden floods. At the same time, the flood control standard is low, the forecasting and early warning system is lacking, and many factors are superimposed, making small and medium-sized rivers a high-risk area for floods. " Zuo Qiting, a professor at Zhengzhou University School of Water Conservancy and Transportation, introduced.

  Take multiple measures to ensure flood control safety. Yao Wenguang, director of the Department of Flood and Drought Disaster Prevention of the Ministry of Water Resources, said that before the flood season, the water conservancy department carried out all-round inspections on river flood discharge, dike safety, and plan preparation, highlighting the river-related risks such as blocking backwater of bridges and culverts across ditches and silting of ditches, and urging all localities to improve plans and eliminate hidden dangers. During the flood season, we should adhere to the rolling forecast and early warning, improve the "call-to-answer" mechanism, and urge water conservancy departments at all levels to strengthen inspection and duty, and preset rescue forces, materials and equipment to ensure that dangerous situations can be found, reported and disposed of in time.

  All localities heard of the "flood" and moved to implement various measures in detail. Hubei province has improved the early warning "call-and-answer" mechanism that integrates pre-response and goes directly to the front line to ensure that information reaches people. Jiangsu Province has completed the compilation of early warning response mechanism schemes for nine important flood channels, such as Sanhe Sluice and Huaihe River Inlet Channel, to ensure the flood safety of small and medium rivers.

  "In the long run, it is necessary to coordinate emergency response and long-term planning." Zuo Qiting introduced that it is suggested to further strengthen the system management of small and medium-sized rivers, coordinate the upstream and downstream, left and right banks, main tributaries, scientifically formulate plans, carry out system management, promote dike reinforcement, dredging, water system connectivity, hardening and beautification, etc., and improve the overall flood control capacity. Next, the Ministry of Water Resources and related areas will speed up the pace of governance, giving priority to the implementation of river sections with cities at or above the county level, important towns and relatively concentrated populations along the river.

  Compacting responsibility to ensure the safety of small and medium-sized reservoirs in flood season

  At present, more than 98,000 reservoirs of various types have been built in China, which is of great responsibility to ensure the safety of reservoirs during flood season.

  There are 4 medium-sized reservoirs and 26 small reservoirs in Wu ‘an City, Hebei Province, at the eastern foot of Taihang Mountain. The mountain is high and steep, and the source is short and the current is urgent. Once it encounters a rainstorm, the water level of the reservoir rises and falls sharply. "When the inspection is in place, I have a bottom in my heart." Huo Hongjun, a staff member of Shangkou Reservoir, said, "The reservoir operates at a water level below the flood limit. We have comprehensively overhauled the power generation tunnel, flood discharge tunnel, generator set and early warning equipment, and inspected key parts twice a day to ensure foolproof."

  The "three responsible persons" of administration, technology and inspection must all be in place, and the key parts of the reservoir such as spillway and drainage facilities and the preparation of protective measures should be comprehensively investigated. In principle, all dangerous reservoirs will run empty during the main flood season … … A series of measures protect the reservoir from flood. "The key to reservoir flood control is prevention. When the responsibility goes to people, measures can be put in place. " Yao Wenguang said that when the reservoir stores and discharges flood, all personnel in the flood threat area should be transferred immediately. When the reservoir is in danger, it should be handled in time, and the personnel within the affected area should be transferred in advance to ensure the safety of people’s lives.

  All localities should actively explore according to local conditions. Hubei Province requires that the responsible persons of dangerous reservoirs and reservoirs with high water level should be on duty at the dam during heavy rainfall. At present, the monitoring platform of Jingchu Reservoir has conducted telephone spot checks on more than 7,000 people and sent more than 18,000 early warning messages. Guizhou province pays special attention to the 24-hour patrol duty of dangerous reservoirs and reservoirs under construction, and requires that the reservoirs under construction should not be impounded without water storage acceptance.

  Small reservoirs need extra vigilance during flood season. Zuo Qiting introduced that there are about 94,000 small reservoirs in China, accounting for over 95% of the total number of reservoirs. Small reservoirs have some problems, such as early construction time, low standard, unclear ownership and imperfect management. On the one hand, improve engineering measures, promote the reinforcement of small reservoirs and improve infrastructure. On the other hand, strengthen the construction of non-engineering system, strengthen forecasting, early warning, rehearsal and pre-planning measures, and ensure that someone is in charge, can rescue and can transfer in case of danger.

  This year, the Ministry of Water Resources has implemented 128 large and medium-sized and 3,500 small dangerous reservoirs in an orderly manner, and basically completed the construction of rainwater forecasting facilities and dam safety monitoring facilities for small reservoirs before the flood season.

  Precise policy to prevent urban waterlogging

  In the middle of the night of July 6, Guangshui City, Hubei Province suffered from heavy rainfall and accumulated water in many parts of the city. Assemble teams, check hidden dangers and control traffic … … Up to now, Hubei has dispatched 18,000 emergency response forces and more than 2,800 equipment and vehicles, effectively ensuring the safety of urban operation during heavy rainfall.

  In recent years, various regions and departments have intensified their efforts and made positive progress in urban waterlogging control, but there are also problems such as insufficient natural storage space and lagging drainage facilities. "Especially with the acceleration of urbanization, infrastructure such as high-rise buildings, roads and squares has changed the underlying surface to a great extent, and the formation time of urban waterlogging is fast, the flood peak flow is large, and the prevention is more difficult." Zuo Qiting said.

  It is the key to prevent urban waterlogging and identify the risk points. The Ministry of Water Resources requires that urban flood control should be placed in the river basin flood control system, and the "four preparations" for forecasting, early warning, rehearsal and plan should be done well, and the measures of "refusing, bypassing and discharging" should be implemented. Hubei focused on urban main roads and drainage canals in waterlogging-prone sections, overhauled and maintained the facilities of drainage pumping stations in 463 cities, and timely rectified 278 waterlogging-prone points; Jiangsu has completed the renovation of 255 urban flood-prone areas (points).

  Urban waterlogging should not only be prevented, but also treated. Zuo Qiting introduced, discharging, stagnation, infiltration and storage, and making full efforts. Arrange the drainage pumping station and other equipment, unblock the backbone drainage channel, let the accumulated water be discharged and the flood flow away; Increase urban green space and build a sponge city to allow rainwater to seep down; Keep the urban wetlands well, improve the rainwater storage facilities, and let the rainwater have a place to store.

  "Urban construction should find a way for floods." Zuo Qiting introduced that rivers, lakes and reservoirs are natural flood storage places, and rivers are natural flood passages. The concept of green development runs through the whole process of urban planning and construction, and production, living and ecological space are rationally arranged, taking a connotative, intensive and green high-quality development path.

Guan Qingyou: The worst period of this year’s economy has passed, and 2020 will be an asset year.

  Cctv news(Reporter Gao Shijia): On April 17, the National Bureau of Statistics released the GDP data for the first quarter of this year. In the first quarter, the gross domestic product (GDP) was 20,650.4 billion yuan, which was 6.8% lower than the same period of last year at comparable prices, showing the first negative growth for many years. The sudden COVID-19 epidemic has had a great impact on China’s economic operation. How should we view the growth of -6.8% in the first quarter? What is the future direction of the real economy and capital market?

  For example, Guan Qingyou, president of the Financial Research Institute and chief economist, believes that the negative growth of 6.8% truly reflects the impact of the epidemic on the domestic economic operation. The bottom of the economy has been confirmed throughout the year, and the worst period has passed. After the data is released, both macro policies and enterprises can go into battle lightly, and the space and rhythm of policy operation will be more clear. Corporate bail-out and people’s livelihood assistance will be the focus of future macro policies. At present, both enterprises and individuals should keep the bottom line thinking, lower expectations and ensure cash flow and basic rate of return. China’s economic resilience is still there. If we remain optimistic, it will be even better next year.

  This year’s economic bottom has confirmed that the worst is over.

  CCTV reporter: How do you view the negative economic growth of 6.8% in the first quarter?

  Guan Qingyou:The growth in the first quarter was -6.8%, which was basically determined to be the bottom of the whole year from the data. The data in March has rebounded from the previous month, and the data in the next second quarter will definitely be better than that in the first quarter.

  -6.8% is a realistic data. On the one hand, it reflects the actual impact of the epidemic on economic operation, suggesting that we must attach great importance to the sharp economic decline, support enterprises to bail out, stimulate consumption, and release vitality through reform. On the other hand, if the impact of the epidemic is clarified, macro policies and enterprises can go into battle lightly, clarify the space, intensity and rhythm of policy operation, stabilize employment and stabilize the basic market.

  Of course, it must also be noted that the statistics reflect the basic situation and there is also a "survivor bias". In many fields and industries, the actual impact is more serious, and it is indispensable for enterprises to save themselves. Under the current domestic macro-policy space, it is very urgent to start with factor reform and stimulate a new round of growth vitality.

  Objectively speaking, China has great room for economic growth and strong resilience. As long as we think correctly and take proper measures, China will surely recover fastest and best among the major economies in the world. In the long run, China’s economic growth potential is still great, which is unique among the major economies in the world.

  CCTV reporter: What impact will the global epidemic spread have on China’s economy? Has the worst of this year passed?

  Guan Qingyou:The spread of global epidemic will also have an impact on transportation, shipping and international trade in the future. Epidemic prevention and control requires global cooperation and joint efforts. We should also be mentally prepared to deal with the impact of the epidemic for a long time. It can be said that the current world is in a great change that has never happened in a century. Apart from the economy, we should be aware of the subsequent changes in the world economic order and political order.

  The biggest impact of this epidemic — — The period of economic shutdown has passed. At present, China has started to focus on epidemic prevention and control, and at the same time, to resume work and production. Although the subsequent chain reaction still exists, it will be expected.

  Personally, I think the worst of this year has passed. Although a large number of enterprises may be eliminated because of the epidemic, it is cruel, but the crisis is organic, and at the same time, more new formats, new business models and new technologies will be born, and the process of coping with the crisis is also an opportunity to make up for shortcomings and promote reform. It is now easier to reach a consensus on deepening reform, speed up the search for new kinetic energy for economic development, and release new reform dividends.

  2020 will be an asset year with many structural opportunities.

  CCTV reporter: What do you think of the capital market this year?

  Guan Qingyou:The economic data of the first quarter and the quarterly report of listed companies have been released one after another, which is a bad thing for the capital market as a whole.

  Personally, I am very optimistic about this year’s market. Because the first half of the year is definitely in a bottom area, with the announcement of the first quarterly report of listed companies, the impact of the epidemic on enterprises is gradually clear, and the expectations are clear. From the perspective of the capital market, 2020 will be an asset year.

  This year’s macro policies are relatively restrained, and there will be no flooding and no unexpected easing. Therefore, the overall index of the stock market will not rise sharply as in 2015, but there will be many structural opportunities. This year, we mainly look at sectors and individual stocks, not the overall index. Many sectors have been greatly affected by the epidemic in the short term. After the shock, prices and valuations are more matched, and assets with higher cost performance have more opportunities to buy.

  At this time, the anti-risk ability of leading enterprises with relatively stable performance will be highlighted, and the leading effect of "the strong will remain strong" will continue. There are also many consumer sectors that have been significantly affected by the epidemic. The short-term decline in performance is relatively severe, but the cost performance will increase, and there is room for growth in the future, which is an opportunity to buy. Opportunities for technology stocks mainly depend on whether there are independent core technologies, and enterprises with low added value in the industrial chain at both ends will have high anti-risk ability, which requires in-depth analysis and identification by investors.

  CCTV reporter: How do you assess the impact of this epidemic on the industrial chain of the real economy?

  Guan Qingyou:The reconstruction of the global industrial chain under the influence of the epidemic is certain, but it is still uncertain how strong it is.

  I have a deduction conjecture. Looking at the extended cycle, the state of globalization can be divided into three cycles. The first cycle is 1945— In 1991, from the end of World War II to the disintegration of the Soviet Union, this stage was the formation of two camps and two parallel markets in the East and the West. The second cycle is 1991— In 2016, with the expansion of globalization and the gradual formation of a unified global market, China gradually integrated into the world and became the world’s factory. Many countries, including China, benefited from globalization and developed rapidly. The third cycle began in 2016, with Trump being elected as the president of the United States as the node. The degree of anti-globalization has deepened, or semi-globalization and regionalization have become more obvious. The economic ties between countries in the world will not be cut off, but the overall situation is much weaker than before.

  According to this calculation, from 2016, this state will continue for decades in the future. If the deduction comes true, it will be a very regrettable scene. China must also learn to face the new economic order and rethink the future development strategy.

  Corporate bail-out and livelihood assistance will be the focus of future policies.

  CCTV reporter: What are your expectations for future macro policies?

  Guan Qingyou:This year’s macro policy should focus on corporate bail-outs and people’s livelihood assistance. To bail out enterprises, we should not only have quantitative tools, but also have price tools. If the interest rate is only cut between the central bank and financial institutions, it is likely to form financial idling. Therefore, it is necessary to directly reduce the loan interest rate to solve the problem of financing difficulties and expensive financing for SMEs. On the issue of enterprise bail-out, financial institutions need to make profits to small and medium-sized enterprises, and gradually realize the marketization of interest rates in this process. Only by allowing thousands of small and medium-sized enterprises in Qian Qian to survive as much as possible can we solve the employment problem and stabilize the basic market.

  With regard to people’s livelihood assistance, the key point is to prevent a humanitarian crisis, and to increase assistance subsidies for the unemployed and needy groups. For example, the issuance of consumer vouchers is very good. Based on our basic national conditions, it is targeted to low-income groups, difficult groups and unemployed groups.

  CCTV reporter: Which risk is greater, economic inflation or deflation? How should individuals deal with various risks?

  Guan Qingyou:Now there are two States: inflation from CPI and deflation from PPI. So now the economy is in an atypical stagflation state, and the situation is more complicated. But we might as well jump out of the framework of western textbooks and return to traditional Chinese wisdom — — In the year of great disasters and epidemics, you are frivolous and have a rest.

  It is necessary for ordinary people to tighten their belts and reduce unnecessary expenses. This is a passive response. Furthermore, try to hold assets that are less affected by inflation or deflation, such as holding money in deflation and holding assets in inflation. As for how long it will last, investors need to strengthen their own learning and have a basic understanding and judgment of the status quo.

  Investment risks are great, especially in the complicated period. For individuals and families, the most important thing is to stabilize cash flow. Ordinary people should lower their income expectations, such as investing in some sound bank wealth management products. We should have a bottom line thinking, constantly improve our cognitive ability and professional level, and have our own core competitiveness. There is no point in being pessimistic now. Next year will definitely be better.

From "Boys with Stories" to "Pupils in Film and Television Plays", Director Chen Chang’s "Reversing Life" | Interview

Author: fried hawthorn with sugar

Reprinted source: a little drama reading (ID: yidianjd)

What will the director look like if he can shoot an online drama like "Reverse Life" that makes people laugh from beginning to end?

Before the interview, a little drama read countless times to imagine this problem. Especially when I saw his resume from a dancer to a drama actor, and transformed into a drama director, a TV column director and a film and television drama director, my heart was actually a little uneasy. In previous media reports, he is a "male classmate with stories" and a representative of "obviously relying on face but relying on talent to eat".

Chen Chang is really busy, and this kind of "busy" can also be understood as a bumper harvest.Reverse Life will end tonight.Previously, the dual-platform webcast volume of the drama has exceeded 700 million, and the Tik Tok broadcast volume is 660 million, ranking among the little dark horses; A female emotional drama directed by him"Their Counterattack" was also officially announced in May and will be launched soon.. He himself is busy at the shooting scene of Love.This is another urban emotional drama created by Ning Meng Film.

The interview was conducted in the evening after the filming, and then he had to join a new round of meetings. The most obvious feeling is that, unlike "I like you" and "Reverse Life", which give people a sense of laughter, there are quite a few brain holes. Director Chen Chang is more rational and true, and he believes in the natural precipitation in his exploration and experience.

After entering the film and television industry for nearly ten years, he bluntly said that he was only a "primary school student." He devoted himself to exploring the fusion proposition of romanticism and realism, and permeated all his works with emotion; He admits that happiness is regarded as one of his film and television styles, but he also says that he doesn’t deliberately choose scripts with happiness elements. It’s just that the experience of nearly 20 years has made happiness something engraved into his bone marrow and blood, which will be loaded naturally when filming.

But life in reverse is slightly different for him.Here’s a new attempt that he "hasn’t done before and may not do in the future".And with "Reverse Life", we will also enter the "reverse life" belonging to director Chen Chang.

Reverse life: in the constant movement,

Cultivation of "Young Directors"

 

"Dance doesn’t seem to be a particularly long road";

"I took several plays and found that the actors at that time were very passive";
Drama is bitter and the pay is not much, but you need to support your family.

Chen Chang summed up his several leaps in just three sentences, from dancing to actors to drama actors. At a very young age, his thinking is very realistic and mature. From the public information, it was in 2004 that he became a director of TV programs, which was about 27 years old.

Drama, TV programs and film and television dramas constitute his work experience for nearly twenty years. The first two have alternated for ten years, and now he has also stayed in the field of film and television dramas for ten years.

Chen Chang became attached to the film and television drama, mainly thanks to the guidance of well-known producer Jiang Yiting. In 2017, the two collaborated on the realistic theme "Accompanying Mom", which attracted a high degree of market attention. In his memory, when he first entered the film and television drama market, he actually didn’t adapt: compared with drama, the shooting volume of TV drama is larger, and its time cost also requires the director to respond quickly. At that time, the pressure will be greater.

It was not until "Newly Married Apartment" in 2015 that everything got a little better. The theme of sitcom made him gradually find the feeling of filming TV dramas, and he also began to integrate his experience on the stage of drama and apply it to the filming of TV dramas.For example, he will pay more attention to the actor’s lines and the tension in the actor’s performance.

Another exampleHe likes to use drama actors more and more in TV plays.Take Reverse Life as an example. Wu Yaheng, the actor of Li Qinghua, the director of my injustice, and Liang Chao, the actor who envies countless people, are all actors who have cooperated with him many times and have rich experience in stage performances.

Zhongzhong Yu, the director, is another person he mentioned, and Chen Chang called him a "close friend" and a "teacher". "Teach me a lot of shooting skills and methods, is Zhongzhong Yu.I am committed to being an idol drama director with a sense of life. I want to make some film and television dramas that combine romanticism with realism, and romanticism is derived from such a person. ". The two also co-directed many film and television dramas, such as The Master of Composition.

Constantly accumulating and groping, the time is 2020.Chen Chang handed over his masterpiece: I like you.Although the film version of Zhuyu was in the first place, once the play was launched, it quickly triggered a real fragrance effect and quickly swept the network. Last year’s "Good Words and Freehand brushwork" also achieved remarkable results.

Continuously handing over high-quality masterpieces, Chen Chang is also known and loved by more young Internet audiences. And his past experience was also called by the media."Male students with stories"However, in Chen Chang’s view, this frequent change is not to change the track, but to complement each other."Every changing stage is ultimately integrated".

Just as the study of dancing and drama can be brought into play in the direction of TV columns, the drama experience is also becoming an important nutrient in the process of directing his film and television dramas. "Reverse Life" is the "atypical answer sheet".

Reversing the new idea: starting with the actor,

Breakthroughs standing on the "leveling line"

 

Chen Chang is always calm and has no taboo.

When talking about "I like you" in 2020, he once bluntly said, "Not losing movies is my most basic requirement for myself"; In 2022, "Reverse Life" was broadcast. In view of the film-and-television discussion of body exchange, Chen Chang also bluntly said: In the past, film and television dramas were just the "leveling line". We can’t go below the leveling line, but we should go up.

"This (body exchange) is not the theme of a rotten street. Until today, I also think that this play has a certain freshness."Chen Chang stressed. How to make "Reverse Life" new?

Chen Chang put the most critical point on the control of actors’ performances.There are often body exchanges in film and television dramas, but how to grasp the unique sense of freshness belonging to the campus of this drama and make the whole drama "fresh and interesting first, then sweet and warm", sweet but not greasy, needs to be achieved through the performance of actors.

He always has his own insistence on the choice of actors, such as Lin Yushen’s overwhelming opinion in "I like you" and "Reverse Life". From the beginning, he was determined to choose "raw face".He set four criteria: first, it is consistent with the role of the script; Second, the actor’s image is clean and pure; Third, have enthusiasm for the role; Fourth, actors should not have too heavy personal labels.

During the audition, Chen Chang took a fancy to Ma Sichao (played by Qiao Nan) at a glance. "He is clean and pure, with light in his eyes and enthusiasm for the role. He has the feeling of being a boy’s grandfather and the shyness of a girl. " The image of Zhou’s long hair on the first side is also amazing to Chen Chang, which is quite different from the previous temperament of "vigorously charming", and her speech is indeed somewhat boyish.

In this way, the two most important actors are sure. In order to help them find the role of Mu Xiang in the play as soon as possible and feel different from Qiao Nanshi, Chen Chang spent a lot of time: for example, let them perform "proofing" for each other, and at the same time interview some male and female staff on the cast to find performance inspiration.

Chen Chang doesn’t think that there must be an important node to witness the actor’s "enlightenment", which should be a gradual process.And when he saw "Qiao Nan" still played by Zhou put his hand on the taekwondo players and jumped up to say hello to "Mu Xiang" played by Ma Sichao, he felt that everything was right at that moment.

The group image of "no instrumental villain" is an important reason why many viewers think this drama is eye-catching.An interesting point,Different from the "unfamiliar face" of the leading role, there are a large number of mature actors familiar to the audience in the supporting role, which also balances the market awareness of the cast to some extent.

Speaking of group image-building, in Chen Chang’s view, the protagonist should undertake the narrative function. In contrast, the script space of the supporting role is limited, but the performance space is relatively large. "They don’t have to bear too many logical lines, but there are often some places where inspiration breaks out," he explained.

In the play, Li Qinghua, the director of injustice, and Qiao Yuanshan, the "super brother" Qiao Rui, who have a traditional sense of China’s father’s sight, have deepened the audience’s memory because of the contrast of the character setting itself, the plump characters and their own sense of joy. In particular, "Li Qinghua" and Chen Chang collided with each other on the spot, resulting in a hilarious scene of "the sad monument is so cold".

From the leading role to the supporting role, it constitutes a "new character".

Reverse life: the comedy buff is full,

Why is it an "atypical answer sheet"?

The second key to making a new idea is Chen Chang’s integration with bone and blood:Happy feeling. The typical comedy situation of body exchange also gave him more room to play.

For many years, Chen Chang has always insisted on injecting certain joyful elements into film and television dramas, making them the nourishment of content and synthesizing some "hostility". Even in his view,This joy is not limited to any subject.This is also reflected in his previous dramas such as "I like you".

The filling of joyful elements in film and television dramas is compared by him to a process of constantly "filling holes", which is to put new soil into the space left by scriptwriters.It’s just that "Reverse Life" has a little more space, almost 50%.The joining of the new generation of actors is also a "plus item" to strengthen the drama’s happiness: they have more time to ensure the shooting and rehearsal of the crew, because "comedy needs rehearsal."

"You have to do your homework the day before shooting, take your books, adapt to the whole scene during shooting, and rehearse those lines with the actors, including the establishment of baggage, and so on. Because the rhythm of comedy is a little stronger than that of ordinary drama, and then it is a little bit dead.Comedy looks casual, but it is a very certain art.",Chen Chang explained.

Sometimes, Chen Chang will also demonstrate on the spot.He needs actors to follow their own rhythm in the formation of baggage, but at the same time, they should also find the characteristics of actors themselves to blend in and form some chemical reactions together.As for how much joy each actor can finally give, he is "tolerant": teaching by hand, and then editing, can be adjusted.

In fact, it is not interesting to disassemble the creative process of the sense of joy itself, because for Chen Chang, this keen sense of joy is more due to his work experience and the usual accumulation, and will naturally be brought out when needed.

The experience of the drama stage made it easier for him to open his imagination; At the same time, he will continue to draw nutrients from film and television dramas and internalize them into his own things. But in his opinion,Everything can be expressed with joy, but it should also be based on life and emotion, and cannot be suspended.

Just like the scene of Qiao Nan’s "glow under his arm" in "Reverse Life", it must be ironic, but in Chen Chang’s mouth, maybe the creator only saw the glass reflection at first. However, this relatively "grandiose" lens language skillfully magnifies the joyful elements of TV dramas. This is actually the image style customized by Chen Chang for the play.

And so on, there are scenes in which two protagonists talk to their hearts, dialogues of characters under the curtain, etc., all of which highlight the actor’s self-expression through concrete or spare space. These in themselves are in line with the fantasy theme of body exchange, "it has never happened before, and it may not happen in the future."

Although Chen Chang is too busy to catch up with "Reverse Life" episode by episode, he is also actively accepting feedback from the market. For those bugs that were only realized after watching the barrage, he accepted it frankly:To some extent, that is the "necessary price" for comedy exaggeration.

The "atypical" in "Reverse Life" is his insistence on actor selection, and also his buff in joy and fantasy; However, this drama is a typical "Chen Chang’s Works", which absorbs a lot of nutrients from the past drama experience, and the discussion of emotions also runs through: the core of comedy fantasy is the theme of mutual redemption and common growth, and at the same time it is permeated with the discussion of practical issues such as family of origin and personal values.

"Pupils" Chen Chang:

Experience will refine nutrients, and I want to shoot brotherhood.

 

Chen Chang’s next work, Their Counterattack, is a typical female emotional drama, but also a completely different style from Reversing Life.He bluntly said that the most attractive thing about this drama is the sense of independence in every woman.

Although Chen Chang doesn’t feel that his works are diverse, butHe is really trying all kinds of subjects.. Compared with most people, he is not willing to emphasize the so-called "self-style" too early. He believes in natural precipitation and that time experience will naturally extract nutrients.

Just as the experience of drama and TV programs will become his nutrition now, so will the film and television drama shooting itself."Just like shooting an idol drama at the beginning is to’ have beautiful lights, beautiful atmosphere and beautiful characters’, you will gradually find that you need to be grounded, and you should start from the perspective of life and tap the interest from life."For example, Chen Chang said that this is what he will continue to integrate and bless in the future.

In his view, the development of style is not a day or two of sudden enlightenment, but a step-by-step formation of their own shooting habits and creative habits, and then summarized.This is a process of constant maturity, and he believes that even if he returns to drama or TV programs again, he will also have new experience in film and television drama production to learn from.

At present, he just wants to go down the road of TV series. He wants to try a theme that focuses on brotherhood like Genesis, and also wants to try a realistic theme with black humor like I am Yu Huanshui. Walking slowly step by step, he will eventually reach the peak he wants. And we are looking forward to more high-quality works and meeting the audience as soon as possible.

Flying in the sky | Listening to astronauts telling hard-core stories behind "holding hands" in space

CCTV News:The rendezvous and docking of the Mengtian experimental module and the space station assembly can be said to be the space "handshake" of the two spacecraft with the largest mass in China’s manned spaceflight project, and the control difficulty is obviously increased. To this end, researchers have also come up with many ways to enable them to "shake hands" steadily in space.

This time, the Mengtian experimental module will rendezvous and dock with the space station assembly, which can be said to be the most "powerful" space handshake in China’s space history. The Mengtian experimental module weighs 23 tons, while the space station is a "four-module" combination consisting of Tianhe core module, candlestick experimental module, Shenzhou-14 manned spacecraft and Tianzhou-4 cargo spacecraft, with a total weight of more than 60 tons. In order for these two behemoths to complete rendezvous and docking, they must "shake hands steadily" and minimize the impact force between them.

Liang Xiaofeng, overall chief designer of space station system electricity of the Fifth Academy of Aerospace Science and Technology Group:In order to overcome the impact of large impact on equipment during docking, in fact, some special designs and damping designs have been made in rendezvous and docking to adapt to large-tonnage and large-mass rendezvous and docking. In the whole docking process, the relay is slowed down or reduced to protect the whole docking mechanism and reduce the impact on the whole assembly and equipment.

Another big test of this rendezvous and docking is that the Mengtian experimental module carries two huge solar panels, which are not only large in area, but also made of flexible materials, just like carrying a pair of huge "soft wings" for rendezvous and docking, and the control difficulty can be said to be unprecedented. To this end, researchers also designed a set of solar array deployment scheme for Mengtian experimental module, which improved the controllability and ensured the safety and success of the mission.

Chao Luo, the overall designer of the space station system of the Fifth Academy of Aerospace Science and Technology Group:When we docked, the solar wing kept shrinking and flying. After docking, we completed the second deployment of the solar wing.

Space "holding hands" is difficult, and multiple measures are taken to ensure success.

The Mengtian experimental module is similar to the candlestick experimental module launched three months ago, but the rendezvous and docking process is "difficult" and "difficult". In order to solve these problems, researchers have designed a large number of plans and measures to ensure the final success of the rendezvous and docking.

According to reports, the first difficulty of this rendezvous and docking is that after the Mengtian experimental module is in orbit, there is a big deviation from the angle of the sun, which leads to weak power generation capacity of solar panels and energy shortage. If the rendezvous and docking cannot be completed within the specified time, it is necessary to urgently adjust the posture of "Mengtian" towards the sun to replenish energy, which will lead to the delay of rendezvous and docking time. To this end, researchers have specially formulated a failure plan for the rendezvous and docking mission for "Mengtian".

The second difficulty lies in the goal of this rendezvous and docking — — On the space station assembly. In the last rendezvous and docking, the combination was in a symmetrical configuration, but in this rendezvous and docking, the combination was in an L-shaped asymmetrical configuration, which significantly increased the difficulty of the on-orbit attitude control of the space station.

Chao Luo, the overall designer of the space station system of the Fifth Academy of Aerospace Science and Technology Group:Pitch offset is adopted at a certain angle, which can save a lot of propellant and effectively use space torque. Then, when the Mengtian module enters the final translation and convergence section, the pitch angle will be adjusted to a completely horizontal state to wait for the rendezvous and docking of the Mengtian experimental module.

In addition, when Mengtian approaches the assembly, it is necessary to start the reverse thrust engine to slow down, and the plume of the engine will interfere with the attitude of the assembly, which makes it more difficult to dock the Mengtian experimental module with the space station at the last minute. However, under the "careful design" of scientific researchers, Mengtian experimental module accurately identified the relative distance and posture with the space station assembly, and finally achieved high-precision rendezvous and docking through a little approach.

Three-type solar wing provides abundant energy for China Space Station.

After the docking and transposition of Mengtian experimental module and China Space Station, China Space Station will form a T-shaped configuration, and China Space Station will also use three different solar wings at the same time.

During the planning and design of China Space Station, researchers developed three generations of solar wings according to the characteristics and needs of different cabins, each with its own characteristics. Shenzhou manned spacecraft uses the first generation of rigid solar wings, and Tianzhou cargo spacecraft uses the second generation of semi-rigid solar wings.

Liu Bihai, deputy director of the power supply of the Mengtian experimental cabin of the Space Station of the Eighth Academy of China Aerospace Science and Technology Corporation:In the first generation, we used a rigid substrate, which was made of carbon fiber and aluminum honeycomb, and its volume was relatively large. On the basis of the further improvement of the original power demand, our cargo ship uses the second generation semi-rigid solar wing, which uses a carbon fiber frame and a glass fiber net, just like a tennis racket, greatly reducing the weight of the whole solar wing.

Compared with shenzhou spaceship and cargo spacecraft, the two experimental cabins of the space station are very large. At the same time, the experimental cabin also needs to carry a large number of cabinets to complete a number of on-orbit experiments, which consumes a lot of electricity. To this end, researchers have specially developed the third generation of flexible solar wings to ensure the electricity demand of the experimental cabin.

Liu Bihai, deputy director of the power supply of the Mengtian experimental cabin of the Space Station of the Eighth Academy of China Aerospace Science and Technology Corporation:At present, the solar wing used in Mengtian experimental module is our third generation solar wing, which is called flexible solar wing. It has the characteristics of light weight, long life and high power. The power generation capacity of two solar wings in a single cabin is about 18 kilowatts. Generally speaking, the power generation capacity of my single experimental cabin in a dream day can be used by a family of three for three months.

After the combination of Tianhe, Zhentian and Mengtian, the daily power generation of the space station can reach nearly 1000 degrees, making the Chinese space station truly "worry-free".

A new generation of solar wings empowers "dream days"

A new generation of flexible solar panels adds new impetus to China Space Station. What is this flexible solar panel like? What are the characteristics? Follow the reporter from the reception desk to have a look.

General Station reporter Chen Qingbin:The electric energy converted from solar energy is the energy source of spacecraft in orbit. What is different from ordinary spacecraft is that on the Mengtian test module launched this time, it is such a pair of "soft wings" behind me — — Flexible solar panels. As you can see, the veneer of this solar panel is less than 1 mm thick, which can be described as "as thin as paper", and there are many small mirrors with dark blue glass on it. Each small mirror is like a small space power station, which is connected in series and in parallel to form a solar cell array to provide a continuous energy guarantee for the spacecraft.

The solar panels of Mengtian experimental module adopt the latest generation of solar array technology in China — — The flexible triple junction gallium arsenide solar cell array is composed of hundreds of thousands of flexible solar cells. The weight per unit area of these flexible solar cells is only 50% of that of traditional solar cells, but the photoelectric conversion efficiency has been greatly increased.

Su Bin, Head of Solar Array Project of Space Station of CLP Energy Co., Ltd.:The conversion efficiency of triple junction gallium arsenide solar cells is more than twice as high as that of traditional ground silicon cells.

In order to ensure the on-orbit life of the space station, the research team continued to develop high-voltage flexible solar array technology, and completed more than 80,000 high-and low-temperature cycle tests to ensure the structural stability and flexibility of the solar array. It is expected that the design life of the low-orbit solar array will be improved from 5 years to 15 years.

China’s new regulations clarify that food and drug complaints can request mediation from market supervision departments.

  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.

Bird flu, what you should know.

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. ▲

Ask M7 to upgrade M9 to the same smart driver, and the price increase is nearly 9,000, which is equal to CDC’s free delivery?

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).
