After more than 600 consecutive days of "zero reporting" of local cases, COVID-19 local confirmed cases appeared in Taiyuan. The epidemic situation is the command, and the city’s four-level comprehensive management center responded quickly, with 9788 grid workers doing their best to fight, doing a good job in investigation and prevention, and providing service guarantee in detail. It explained what is "useful in peacetime and useful in wartime" with practical actions, and set up a "bridge to the heart" to protect the people with true love and built a "firewall" to protect people’s safety.

　　Size 36 feet and size 38 shoes.

　　At eight o’clock in the morning, downstairs in Fenghuang Community, jiancaoping district Xincheng Community, Taiyuan City, several residents walked into the nucleic acid detection point with shoes and handed them to the grid staff Li Na. Li Na and her colleagues happily put on their shoes and began to prepare for a new round of nucleic acid collection.

　　Since February 25th, the whole area of jiancaoping district has been managed as a precautionary area, and 985 grid workers in the whole area have taken off their red vests and put on protective clothing, thus entering a "wartime state". The first round of nucleic acid testing began at 11: 30 pm, and the medical staff took samples. Li Na and her colleagues entered information. After finishing at 3 am, they slept for more than two hours, and continued testing at 6 am until 4 pm … …

　　Cooperate with nucleic acid detection, which is only a part of the grid staff’s work, leading medical staff to carry out home detection, reminding shops and other personnel to do prevention and control in concentrated places, monitoring the temperature of isolated people at home, and checking the vaccination situation, the actual number of people under control and the nucleic acid detection situation, so as not to miss one household or one person … … The footsteps kept on and the phone kept on. After a few days, Li Na and her colleagues were hoarse and their feet were swollen.

　　"When we got up that morning, several grid workers found that our feet couldn’t fit into the shoes, so we tried to send a message in the group and wanted to ask if anyone sold shoes. I didn’t expect the residents to take the initiative to borrow their shoes and wear them. It was quite touching. My feet are size 36, and I have been wearing size 38 shoes for the past two days. " Li Na said.

　　Being a "warrior", Li Na is very tired, but she doesn’t panic at all, because they usually work hard: "I have more than 20,000 steps every day. If it is lower than this number, it means that my work is not done." Day after day, I went to the house to find out how many people there are, how to contact them, which family has disabled people and elderly people living alone who need special care, and which family has patients who need special attention. I have long been aware of it, and those steps I usually saved have been exchanged for wartime.

　　There are many grid workers like Li Na. Usually, they walk around the streets, find hidden risks, find clues about the epidemic situation and resolve contradictions and disputes, which are the "stabilizers" of the community grid; During the war, they heard that they were retrograde, gave full play to their advantages of familiarity with people, places and situations, responded quickly and accurately, and patiently publicized and persuaded them, which became the "reassurance" of the masses.

　　Mom is in Shanghai and aunt is around.

　　"My child is 10 years old and has been at home for three days. I hope I can help me see him!" A few days ago, Guo Jing, a grid member of Hepingyuan Community in Wanbailin District of Taiyuan City, received a call for help. I learned that the child’s father died and his mother went out to work, which was usually taken care of by his grandfather. Three days ago, grandpa went back to Taigu District, Jinzhong City to handle affairs. Because the local epidemic control failed to come back in time, the child had to stay at home alone, and his mother in Shanghai gave him some takeout for three meals a day.

　　After understanding the situation, Guo Jing knocked on the child’s door for the first time. Looking at the lunch boxes and leftovers piled up on the dining table, the garbage on the ground, the quilt rolled into a ball on the bed, and the two socks with different colors on the child’s feet, Guo Jing’s nose was sour, and she rolled up her sleeves and began to fold the quilt, sweep the floor and clean the dining table. After cleaning up, considering that the children can no longer be left alone at home, Guo Jing decided to send the children to the small dining table where they often go to stay. Find out the clothes for the child, make the bedding, and pack the books. She handed the child to the teacher at the small table. After that, Guo Jing has been paying attention to the children’s situation. From time to time, she called the teacher at the small table. When she went to see the children, she never forgot to say, "Mom is far away. If you need anything, call your aunt."

　　"You can come to me if you need me" is the mantra of grid workers and their warmest commitment to residents. Community grid workers in Xincheng provide door-to-door nucleic acid detection services for the elderly with inconvenient legs and feet, grid workers in Longbao Community apply for "trip code" for the elderly who use the old-age mobile phone and issue health certificates to facilitate their travel, and grid workers in Bayi Community deliver food, water and medicine to the isolated people at home, handle emergency affairs and disinfect domestic garbage … … From living security to garbage disposal, grid workers put themselves in the residents’ shoes and do everything possible to provide fine services for isolated people, especially those in difficulty and special groups, and truly become "caring people" of ordinary people.

　　Prevention and control of small grid and anti-epidemic power

　　Fan Lei is a grid worker in Chaoyang Community, Nanzhai Street, jiancaoping district. There are 216 households and 613 people in 4 residential buildings in the grid. After the outbreak, she built a "grid in the grid", which greatly improved the work efficiency and strengthened the anti-epidemic force by relying on the strength of the masses.

　　Enthusiastic residents who are familiar with each other at ordinary times have now become the backbone of the "grid in the grid". They are divided into three anti-epidemic volunteer groups, namely, the old, the middle and the young, and their division of labor has their own emphasis: the 18 uncles and aunts in the old group are all old residents in the community, and they are very familiar with their neighbors. One person can greet the neighbors of the next unit during nucleic acid testing, and the number of people who check is even better; The 10 uncles and aunts in the middle-aged group are mostly teachers or employees. They are everyone’s "fire extinguishers". They take time to popularize epidemic prevention knowledge and health guidelines in the group, answer questions and dispel negative emotions; Most of the youth groups are preparing party member and college students. Young people are quick-witted and agile, helping grid workers to enter and collect information, helping to do disinfection and issuing out-of-town cards.

　　With the joint efforts of all, there are fewer and fewer voices of anxiety in the community, fewer and fewer cases of gathering in the courtyard, the time for nucleic acid detection has been shortened from 10 hours in the first round to more than 3 hours in the fifth round, and residents’ cooperation with grid workers and epidemic prevention work has become higher and higher.

　　Watching Fan Lei’s "grid-in-a-grid" exert its energy, the other 11 grid members in Chaoyang community also rushed to imitate and set up volunteer groups in their own grids. The grid workers who are active around the masses, at the critical moment of facing the epidemic directly, have condensed the powerful forces of residents’ self-government and joint anti-epidemic in small squares, and built a "concentric circle" that is shared and co-governed. The bigger it is, the clearer it is.

　　Member of the Standing Committee of the 12th Central Committee of Jiu San Society and Vice Chairman of the 13th Central Committee. Member of the 10th Chinese People’s Political Consultative Conference and the 11th Standing Committee of Chinese People’s Political Consultative Conference.

　　The list of winners of the 15th "Five-One Project" for spiritual civilization construction was recently announced, and 10 works in Beijing won the Excellent Works Award. They are: the movie The Wandering Earth and Operation Red Sea Zhou Enlai Back to Yan ‘an, the TV series The Most Beautiful Youth, Rivers, the song We Are All Dreamcatchers, the Power of Rejuvenation, the radio drama the Central Committee of the Communist Party of China in Xiangshan, the book Going North and A Story in the Clouds. Beijing Youth Daily and Beijing Headline APP launched the column "Jingpin Boutique: Five Behind the Scenes", and today continue to tell you the behind-the-scenes stories of 10 literary and artistic masterpieces.

　　Guo Jingyu, a screenwriter and director who has created many excellent works such as Blade 1937 and Iron Pear Flower, is recognized as "viewing guarantee" in the industry. After the TV series "The Most Beautiful Youth" won the "Five One Project" award, Guo Jingyu, as the producer, admitted that this honor is of great significance: "This drama has made me re-recognize the true value of a literary and art worker."

　　Six screenwriters

　　Spend seven years writing plays.

　　The Most Beautiful Youth is a youth drama produced by Guo Jingyu, directed by Xing Mao Ju and starring Liu Zhiyang, He Yuhong, Zhao Hengxuan and Jia Hongwei. The TV series tells the story that in the 1960s, 18 graduates from all over China, represented by Feng Cheng and Qin Xuemei, and Chengde Weichang Forestry Department formed a pioneering team and actively responded to the call of the motherland for afforestation.

　　The script creation of "The Most Beautiful Youth" lasted for 7 years, with a total of 6 screenwriters of different ages, 32 entrepreneurs of the older generation and hundreds of forestry workers in Saihanba Mechanical Forest Farm interviewed, and several drafts were changed, and the lines were constantly revised and optimized until the broadcast. Therefore, Guo Jing called it "a creation rooted in life, but also a persistent creation".

　　"The Most Beautiful Youth" was launched in Saihanba, Chengde on September 8, 2017. After 162 days, it traveled to Beijing, Tianjin, Hangzhou and Saihanba, Chengde, as well as Wulagai, Duolun, Hexigten Banner and wudan, Inner Mongolia. All of them were shot in real scenes, and only 36 episodes were finally broadcast. After conversion, only 6 episodes were shot every month on average — — This is very rare and extravagant in today’s industrialized TV drama assembly line. In Guo Jingyu’s words, this shooting speed is equivalent to The Romance of the Three Kingdoms and A Dream of Red Mansions many years ago.

　　40℃ below zero

　　Fighting for more than a month

　　There are no flow stars in The Most Beautiful Youth, but everyone is a qualified actor with superb acting skills and hard work, and the details that left a deep impression on Guo Jingyu abound in the creation process. Guo Jingyu recalled that in today’s relatively developed computer post-production, in order to restore the real scenes in the 1960s, post-80s director Xing Mao Ju decided to shoot the whole drama in real scenes. "Only in real scenes can actors express sincere feelings."

　　It didn’t snow in Hebei in the winter of the filming year. In order to restore the heavy snow to close the mountain, the crew moved the set scene to the north for nearly 1000 kilometers, and fought continuously for more than a month in the environment of-25℃ during the day and-40℃ at night. No one of the more than 200 young people of different jobs retreated. Among them, Guo Jingyu was very moved by two things: "There is a scene in the script, in which Zhao Tianshan, the captain, rubs his body with snow during the first snow. The script is not difficult to write, but the temperature is too low, so I really dare not let them shoot it, so when I read the script, I suggested that they move the scene into the studio and shoot it locally. But the actor insisted on being serious, and the director agreed. In another scene, the script wrote that Ji Xiurong was emotionally stimulated and danced in a thin red skirt in the ice and snow. The actors also insisted on real-life shooting, and the beautiful dance was supported by a strong will. "

　　"The Most Beautiful Youth" received a lot of praise after its broadcast. Guo Jingyu said that among all the comments and praises, he liked this sentence best: "The Most Beautiful Youth" interpreted the story that happened in Saihanba with the spirit of Saihanba.

　　Make good use of works

　　Cultivate a good team

　　In recent years, the focus of Guo Jingyu’s work has gradually shifted from screenwriter and director to producer. In his view, the broadcast effect of a good work is of course important, and it is equally important to train the team.

　　Xing Mao Ju, the director of the play, is Guo Jingyu’s "apprentice", and he has already made a name for himself in online drama before. Guo Jingyu said frankly that when he gave him The Most Beautiful Youth to shoot, many leaders were worried that he was too young to complete the task. "After six months of shooting, he reported to me. I am relieved at first sight, because he has gone from a lovely ‘ Children’s director ’ Became a ‘ Little old man ’ 。” Guo Jingyu said with a smile.

　　He Yuhong, an actress born in 1996, is a leading actress for the first time. She is very hardworking and under great pressure. In the later stage of filming, she actually shouted out in her dream, "We must plant living trees, and we should dedicate our youth to Saihanba and to the great motherland … …” Guo Jingyu said that it is really rare to talk clearly in a dream and speak so comprehensively. "Others told me this as a joke, but I burst into tears."

　　In Guo Jingyu’s view, it is these young artists who dedicated their youth in their best years, thus creating the most beautiful youth.

With the popularity of the automobile industry, especially as an urban sports vehicle, many TXTs who don’t understand cars think that the SUV with four-wheel drive system is an off-road vehicle, which is completely wrong.

1. -（||）

Off-road performance: Jimny has a good reputation in the off-road circle. Its powerful off-road performance makes it occupy a place in the list of off-road vehicles at home and abroad. Someone once said: "Where Lu Xun can go, Jimny can also go;" Where Lu Xun can’t go, Jimny can also go. " You can imagine how powerful Jimny’s off-road performance is! Short axis, minimum ground clearance of 190mm, approach angle of 37, passing angle of 31 and departure angle of 46, these inherent advantages give Jimny strong off-road performance. The front and rear integral axles and non-loaded body make Jimny have strong chassis rigidity. Jimny is equipped with part-time 4WD system, which can switch freely between 2WD (two-wheel drive), 4wd (four-wheel drive) and 4WD-L (low-speed four-wheel drive). In the low-speed four-wheel drive mode, the output torque of the transmission shaft will be amplified by 2.6 times to cope with Jimny’s limit of 110Nm. Although Jimny has strong cross-country performance, he also has serious injuries. Its front and rear axles adopt open differential, which leads to uneven power distribution when the wheels slip and weakens the ability to get out of trouble. Of course, for cross-country enthusiasts with strong hands-on ability, this is not a problem, and it is inevitable to move the knife on the differential.

Three SUV models,

Off-road performance: Isuzu is a very niche brand in China. Many people have never even heard of it. Compared with Wuling, its reputation is far worse. However, this does not prevent it from having a strong off-road capability. The minimum ground clearance of Isuzu is 225mm, that of approach angle is 26, and the departure angle is 21. There are no shortcomings in the body data. Because it is a hard-core off-road vehicle with a non-load-bearing body, Isuzu mu-X adopts a front double wishbone independent suspension, and the rear whole axle is an independent suspension. The four-wheel drive system adopts part-time 4wd, and both front and rear axles are open differentials. There are 2H (two-wheel drive), 4H (high-speed four-wheel drive) and 4L (low-speed four-wheel drive) modes. Magnify the torque by 2.48 times. In addition, Isuzu mu-X adopts diesel engines, including 2.5T and 3.0T diesel turbocharged engines, in which the maximum power of 2.5T model is 136Ps and the maximum torque is 320Nm, and the maximum power of 3.0T model is 177Ps and the maximum torque is 380Nm, which is very impressive, greatly enhancing the ability to get rid of difficulties.

Da was born in a famous family, under the banner of Little Rabbit Music, and once it was launched, it sucked countless powders. It is not an exaggeration to say that it has ignited the hard-core SUV market. In fact, Toda originated from Nissan’s Navara platform. Navara is a car with less power than Tourer, but as an off-road vehicle, there is no problem in making it durable. As a hard-core SUV that focuses on off-road performance, a non-loaded body is a must, and there is no problem with part-time four-wheel drive. The low-level four-state torque is amplified by 2.7 times. That sounds great, right? More importantly, in addition to the central transfer box, Tuda is also equipped with a rear axle. The claw differential lock is equivalent to the middle and rear two locks, and its ability to get out of trouble is beyond doubt. If you really want to drive a Tuda to play cross-country, you can basically switch to a capable AT tire or MT tire, and most of the situations can be solved.

4、H5

The most pragmatic hard-core off-road SUV of Haval brand belongs to Haval H5, but it is too big to cover, but in terms of off-road, Haval H5 is quite good. It is equipped with a 2.0T gasoline/diesel engine, in which only the maximum torque of the engine reaches 320Nm. Among them, the manual transmission model has part-time 4wd, and with Eaton’s mechanical differential lock, the torque can be amplified by more than 2 times. Coupled with the automatic transmission model with higher configuration and higher comfort, Haval H5 is definitely worthy of the title of "God Car".

Off-road performance: If you only look at the appearance of the X8, you may think that it is an ordinary urban SUV. If you think so, then you underestimate it. The minimum ground clearance of landwind X8 is 200mm, that of approach angle is 27.4, and the departure angle is 24.2, which is far better than that of urban SUV. Moreover, the Landwind X8 also uses a non-loaded body, which is also a major criterion to judge whether it is a hard-core off-road vehicle. Landwind X8 also comes standard with a set of standard part-time 4wd system, with 2WD (two-wheel drive), 4H (high-speed four-wheel drive) and 4L (low-speed four-wheel drive) modes. The center differential has a 50:50 front and rear power distribution. The transfer case is equipped with a torque amplifying gear with the amplification ratio of 2:1, and the rear axle adopts Eaton differential lock, which has the ability to limit the slip between wheels and greatly improve the performance of getting out of trouble.

6. Zhengzhou Nissan-(||)

Off-road performance: paladin is an old-fashioned hard-core off-road vehicle. Why is it called costume? Because it hasn’t been changed in China for nearly 10 years, it seems to have been forgotten by Nissan. However, paladin’s off-road performance and reliability are beyond doubt. In 2004, China driver Lu Ningjun successfully completed the Dakar Rally in a simple modified paladin, which proved that this car was very trustworthy to some extent. Paladin’s four-wheel drive models are equipped with the traditional part-time 4wd system. The power of the engine is transferred to the transfer box through the gearbox. When the transfer box is in the four-wheel drive position, the front and rear axles of the vehicle are hard connected with torque amplification gears, and the magnification is about 2 times. However, paladin’s four-wheel drive system does not have a central differential, so the four-wheel drive state cannot be used on paved roads. Moreover, Shengdu on sale is not equipped with any anti-skid device between wheels, which directly limits its ability to get out of trouble.

Qilu. com December 29 th Do you have a driver’s license?

How long has it been since you learned your driving license?

I’m afraid this is the most frequently asked question of "new drivers" …

Because of the inexperience and mental stress in vehicle operation, novice drivers are prone to accidents or dangerous actions when driving … Don’t say much, use data to speak …

On the 29th, Shandong released the latest data: from January 1 to December 11, 2017, the number of road traffic accidents and the number of deaths of drivers with less than three years’ driving experience in the province accounted for 18.18% and 13.89% respectively.

Drivers who fail to give way according to regulations, speeding, violating traffic signals, retrograde and illegally occupying roads are drivers with driving experience of less than 3 years (inclusive).The main traffic violations.

The driver drives a motor vehicle into the expressway during the internship period,It should be accompanied by a driver who has held a corresponding or higher driving license for more than three years. In violation of this provision, the traffic administrative department of the public security organ shall give a warning or impose a fine of 150 yuan.

Q: Strict management of the internship period of the driver’s license is conducive to the cultivation of new drivers’ civilized and courteous, safe and law-abiding driving awareness and habits. In order to strengthen the management of new drivers, Order 123 further improved the management system of driving license internship:

First, drivers who have newly obtained driving licenses such as large buses, medium-sized buses and tractors will be included in the internship management.

The second is the requirement.When driving a motor vehicle on the expressway during the internship period, it must be accompanied by a driver with a corresponding or higher vehicle driver’s license for more than 3 years.

Third, the driver’s license isIf there is a record of 12 points during the internship period, the driving qualification of the internship model will be cancelled.

Fourth, after the internship period of large and medium-sized van drivers, they should take the knowledge test of safe and civilized driving and receive traffic accident warning education.

Fifth, drivers of large and medium-sized vans.If you record more than 6 points in violation of the law during the internship period, the internship period will be extended by one year; In the extended internship period, if you score more than 6 points but fail to reach 12 points, your internship driving qualification will be cancelled.

Need to be reminded that during the internship period, drivers need to stick internship signs on the back of the car body when driving.

Q: during the internship, the driver drives a motor vehicle on the expressway.It shall be accompanied by a driver who has held a corresponding or higher driving license for more than three years..

Driving a small automatic passenger car dedicated to the disabled,Accompanied by a driver who holds a driving license of a small automatic passenger car or above.

Q: The driver newly obtained a driver’s license for a large bus, tractor, city bus, medium-sized bus or large truck after January 1, 2013.The internship period will be extended by one year if you are scored more than 6 points but not up to 12 points during the internship period..

During the extended internship period, please note the following:

One isYou need to accompany the driver on the expressway according to regulations;

The second isA quasi-driving model that will be cancelled for internship if it is recorded for more than 6 points again;

The third isThose who have been recorded for 12 times in a scoring cycle will be downgraded; Fourth, after the internship period, you should take the education examination.

Q: Before the implementation of the Road Traffic Safety Law on May 1, 2004, drivers were forbidden to drive motor vehicles on expressways during their internship. Considering the acceleration of highway network construction in China in the new century, the increasing number of motor vehicles owned by individuals, and the increasing number of people traveling by car, many drivers have to travel during the internship period, especially go on road trip and other long-distance trips, which require driving on the highway. After the implementation of the Road Traffic Safety Law,No longer restrict drivers from driving on the expressway during their internship.

However, judging from the accidents that happened during the driver’s internship on the expressway, a large part of them were caused by low driving skills and lack of experience. Order No.123 borrowed from foreign practices.It is stipulated that drivers who drive motor vehicles on expressways during the internship period should be accompanied by drivers who have held corresponding or higher driving licenses for more than three years.

Among them,Driving a small automatic passenger car for the disabled can be accompanied by a driver who holds a driving license above the small automatic passenger car.

However, during the internship period after the increase of the quasi-driving type, driving the original quasi-driving type motor vehicle is not subject to the above restrictions.

Q: The implementation of the law needs the protection of the state’s coercive power, but more needs citizens to consciously abide by the law.

The implementation of the driver should drive a motor vehicle on the expressway during the internship periodThe requirement of being accompanied by a driver with a corresponding or higher driving license for more than three years also depends on the driver’s conscious compliance..

Public security traffic control departments mainly rely on highway toll stations, entrances and exits, service areas, etc. to conduct spot checks.If it is found that the driver is in the internship period and has not been accompanied by a driver with a corresponding or higher driving license for more than three years, and has been driving or is driving on the expressway, the public security traffic control department will impose a fine on the driver from 20 yuan to 200 yuan in accordance with the provisions of Decree No.123, and order him to leave the expressway nearby.; Those who are preparing to enter the expressway will be advised to return after education.

Q: If a driver has a road traffic accident while driving a motor vehicle on the expressway during the internship period, the traffic control department of the public security will determine the responsibility for the accident according to the traffic violations and faults of the driver during the internship period confirmed by investigation.

If there is evidence that the accompanying driver forces the driver during the internship to drive a motor vehicle in violation of road traffic safety laws and regulations and the requirements for safe driving of motor vehicles,If a traffic accident is caused, the accompanying driver shall bear the corresponding responsibility for the accident.

For those who do not constitute a crime, in accordance with the provisions of Article 99 of the Road Traffic Safety Law,Impose a fine of not less than 200 yuan but not more than 2,000 yuan on the accompanying personnel; If a crime is constituted, criminal responsibility shall be investigated according to law.

Q: There are three main situations in which the driver violates the internship management regulations:

One is to drive buses, buses, police cars, fire engines, ambulances, engineering rescue vehicles and motor vehicles carrying explosives, inflammable and explosive chemicals, toxic or radioactive substances during the internship period, or drive motor vehicles to tow trailers. Some of these vehicles belong to public transport, some belong to special vehicles and dangerous goods transport vehicles, and the public safety responsibility is great. The Regulations for the Implementation of the Road Traffic Safety Law stipulates that drivers are not allowed to drive during the internship period.

Second, when driving a motor vehicle on the expressway during the internship period, there is no driver who has held the corresponding or higher vehicle driving license for more than three years to accompany and guide.

Third, the internship signs were not pasted and hung as required. If the driver has any of the above circumstances during the internship, the traffic control department of the public security department will impose a fine of more than 20 yuan and less than 200 yuan.

Q: Those who apply for a motor vehicle driver’s license for the first time and add quasi-driving models will be included in the internship management. Drivers who hold overseas, military and armed police force driver’s licenses are not included in the internship management after renewing their driver’s licenses because of their driving experience.

Q: Drivers of large and medium-sized vans who have scored 12 points for traffic violations during the internship period will be disqualified from the internship. However, if the cancelled driving qualification does not belong to the maximum permitted driving type and meets the requirements of demotion, the maximum permitted driving type should also be reduced according to the regulations.

The Dream of China, starring Liu Yifei, Chen Xiao, Joe, Ada and Jelly Lin, has been very popular recently, and its popularity continues to rise. Meng Hua Lu was adapted from Guan Hanqing’s zaju script Zhao Paner’s romantic rescue.

The background of the story takes place in the Song Dynasty, and the costumes in the play are extremely excellent and elegant, vividly and skillfully highlighting the personality characteristics of the characters. No matter the actors, themes, costumes and plots are excellent, the actress’s shots in this film are even more exquisite and praised by the audience. Of course, all this is indispensable to the credit of lens language design.

Meng Hua Lu has made great efforts in the design and expression of lens language, showing the scenes and characters vividly. The shooting of the whole film is very skillful, and the lens language and picture are very beautiful, artistic, full of meaning and endless charm, presenting pleasing visual effects and bringing excellent visual experience to the audience.

The lineup of Meng Hua Lu is luxurious. The photography director is Yiqin, a senior photographer from Taiwan, China. Director Yang Yang is a famous female directors in China, a national first-class director, and his works have won various awards. The two men joined forces to integrate the theme of the film and the expression of characters’ emotions into the lens language, so that the quality and standard of Dream of China by going up one flight of stairs presented an excellent work to the audience.

In the beginning, Zhao Paner came slowly with a row of bamboo rafts in the distance, his hands alternately swaying bamboo paddles, the breeze blowing gently, the lake waves rippling, and a peaceful and pleasant scene of Jiangnan water town jumped from the paper, giving people an immersive feeling. "arm in arm to punt, the beautiful lake swings."

The camera will play Liu Yifei, the "fairy sister" of Zhao Paner. It is gentle but smart, elegant but atmospheric. This clip has made many viewers watch it again and again, immersed in enjoying this unique beauty like a fairy.

In the fifth episode of the play, the man and the woman talked about drinking, and the wine strength came up, and the eyes looking at each other also changed. Camera switching, a moment to Zhao Paner, I saw her chin staring, charming eyes, a moment to Gu Qianfan, I saw him staring, eyes tender, cut to two people in the same frame, the two sides stared at each other, rendering a subtle atmosphere, at this time, the psychological activities and relations between the two people, can be said to be self-evident.

When parting, the camera switches back and forth between the two. Zhao Paner stood on the small building, Gu Qianfan sat on the boat, and their eyes were reluctant and thoughtful. Zhao Paner eyes flow, tenderness, never removed from Qian Fan, always looked at the boat.

In the face of Zhao Paner’s eyes, Gu Qianfan gradually ignored the words of his peers and didn’t listen to them. When he turned to visit the small building, Zhao Paner’s eyes were still gentle and watery, as if penetrating his heart. At a loss, he had to avoid looking, but he couldn’t help looking in the direction of the pavilion from time to time, showing nostalgia and concern.

Moonlight gently sprinkled on the lake, lingering and lingering, and Zhao Paner watched the boat go away. "whose boat is flat tonight, where to miss the bright moon building." Silent language, with only two people’s eyes and natural scenery, expresses implicit love, which makes people feel unfinished.

The conversation under the umbrella in episode 6, scene selection and composition are very interesting. The background environment is rainy, and the umbrella held by the man and the woman is used to isolate other people in the same space. The camera focuses on the two people, highlighting the main body, making the background completely in Jiao Wai, which enriches the three-dimensional sense of the picture, meaning that this moment is the time exclusively for the two of them, providing a unique space for the next two people to talk.

The raindrops pattering on the umbrella not only created a cold atmosphere, but also narrowed the distance between them, bringing out the psychological changes of the man and the woman, and making them feel depressed. "Holding hands and looking at tears, I was speechless."

The emotion expressed in this lens language is very rich. The concern, awkwardness, pulling and attachment of two people, each picture conveys different emotions to the audience.

On the moon, the willow shoots, and people meet after dusk. In the evening, the sun is setting in the west, and they flirt. When crossing the bridge, Zhao Paner was holding a paper umbrella, and the man was holding the box, chatting while walking, his eyes staring at each other. Although it is a distant vision, there is no voice of conversation between them, but the distance between them and the direction in which their eyes look fully show their mood and relationship at this time.

This shot is poetic and picturesque, and I can’t get tired of watching it. Only a few seconds of a silhouette shot, full of story, made many viewers pause to enjoy this beautiful and romantic scene, and was also made into wallpaper by screenshots.

Meng Hua Lu, whether it is the lens language or the script lines, is carefully polished. The picture is no longer a ten-stage skinning beauty filter for domestic dramas. The lines are properly worded and flowing, the plot is fascinating and natural, and the actors’ acting skills are up to standard without any serious injuries.

Although the recent online comments on Meng Hua Lu are mixed, it is full of some discordant remarks. But on the whole, the film is exquisite in production, high in quality, picturesque and beautiful in picture, and the lens design is rich in layers and originality, which is very worth seeing!

　 　 　 　On June 10th, 2022, the historical biographical film Kumarajiva was launched in Shenzhen Shajing Qingping Ancient Market Film and Television Town.

The scene of the movie "Kumarajiva" boot conference

　 　 　 　Buddhism is one of the three major religions in the world, which has played a positive role in promoting all aspects of China. When talking about the famous monks in the history of China, the first thing that comes to mind is Master Xuanzang. Master Xuanzang went to the Western Regions to learn from Buddhist scriptures and translate Buddhist classics, which had an important influence on Buddhism in China. However, there was a monk who was earlier than Master Xuanzang, and he was Kumarajiva.　

　 　 　 　Kumarajiva is one of the four great translators of Buddhism in China, who translated 74 scriptures and 384 volumes in his life. These translated scriptures not only greatly promoted the development of Buddhism in China, but also had a far-reaching impact on the history of Buddhism in Asia. Master Kumarajiva himself was not only an important messenger of mutual learning between Chinese and Western civilizations on the Silk Road in ancient China during the Wei, Jin, Southern and Northern Dynasties, but also a pioneer in creating national unity. Tagore famously said, "Let life be beautiful like summer flowers and death like autumn leaves." This sentence is a true portrayal of Master Kumarajiva’s life.

Producer Jinzhan Zhang and screenwriter Shi Yike of the film "Kumarajiva"

　 　 　 　On the day of the conference, Shi Yike, the screenwriter of the film "Kumarajiva", Zhang Jinzhan, a famous producer, Wang Dan, a cutting-edge director, starring Purba Rgyal and Wang Jinsong, and Wen Yaoyao, a special opening guest of China Cultural Relics Exchange Center, made a speech.

　 　 　 　Today, Kumarajiva’s translations of Hokkekyo, Amitabha Sutra and Diamond Sutra are still widely read and studied in China, South Korea, Japan and Southeast Asia. Combining the current "Belt and Road" cultural background, the film effectively conveys China’s history and culture to the people of the world, promotes cultural exchanges and cooperation among countries along the Silk Road, inherits the Silk Road spirit and promotes the Silk Road culture.

　 　 　 　The film "Kumarajiva" has attracted much attention from all walks of life since its preparation. On the day of the launch conference, the film producer Zheng Guangzhou, the film planner Huang Jiatai, the chief producer Fu Danchan and all the creative staff all attended, and guests such as Cui Mingchen, editor-in-chief of the Chinese Buddhist Channel of Phoenix.com also attended.

　 　 　 　Young actors enthusiastically joined in, and old actors helped each other.

　 　 　 　Master Kumarajiva was born in Qiuci royal family. He was trapped in Liangzhou for seventeen years by Lv Guang in order to enter the Central Plains eastward and spread eastern and western cultures. After Lv Guang’s death, Kumarajiva went to Chang ‘an to teach Buddhism at the invitation of Yao Xing, Emperor Wen Huan of the later Qin Dynasty, which had a very important influence on the Central Plains culture.

Starring Purba Rgyal, starring Wang Jinsong and artistic director Zhang Zhaoda.

　 　 　 　It is understood that in order to make the characters in the play more in line with history, the young actor Purba Rgyal and the old opera bone Wang Jinsong respectively expounded their understanding of the characters in the play. Purba Rgyal said that compared with his previous roles, the biggest challenge for Kumarajiva, who played as a young man, was how to make himself calm, because Master Kumarajiva was touched by everything, and his greatness could not be described in words. He hoped that he could find inspiration that resonated with Master Kumarajiva in his creation. And with the blessing of Wang Jinsong, an old opera teacher, I believe this movie will be very wonderful. Wang Jinsong, an old opera player, also said that the role he played in this play is different from other roles he has played, so he needs to face it with a more pious attitude.

　 　 　 　Luo Wenbo, a young actor who plays Princess Kamez in the film, also conveyed his blessing through the VCR.

　 　 　 　Strive to restore the real scene, people from all walks of life have high hopes.

　 　 　 　At the press conference, the crew of the film "Kumarajiva" launched the concept poster. The whole poster was mainly in black and white, and the boundless desert turned into a sea of books. Master Kumarajiva bent over the sea of books to translate scriptures, and the theme was concise and clear, at the same time implying that Master Kumarajiva’s understanding of Buddhism and his contribution to future generations were as vast as the sea.

Concept poster of the movie "Kumarajiva"

　 　 　 　According to Huang Jiatai, a film and television planner, in order to enhance the impression of the film, the creative team and his party have visited Kumarajiva’s birthplace Qiuci (now Kuqa City, Xinjiang), Dunhuang White Mata on Dongjin Road, Liangzhou City (now Kumarajiva Temple, Wuwei City), Kumarajiva, where Kumarajiva has lived for 17 years, and Chang ‘an Caotang Temple (now Caotang Temple, Xi ‘an), the national translation venue, and other places to inspect the landscape architecture, feel the humanistic customs, and visit Kumarajiva, Wuwei, Gansu Province.

　 　 　 　In the plot setting, the film focuses on the historical background, showing the important choices he made at the important moment of fate, his great perseverance and willingness to come to Chang ‘an from the Western Regions, his contribution to promoting academic exchanges in culture, art, religion and language between the Western Regions and China, and his contribution to the field of translation studies.

　 　 　 　Interpret the film from four aspects: communication, creation, dedication and professionalism.

　 　 　 　"Communication" — — Since Zhang Qian "hollowed out the Western Regions" in the Western Han Dynasty, the cultural exchanges between the mainland of China and the regions of the Western Regions, Tianzhu, Persia and other countries with different civilizations have been continuous, leaving many cultural heritages and cultural imprints engraved in each other’s civilizations, as well as many historical figures who shine in them. Kumarajiva, the protagonist of this film, is a typical representative. His ancestral home was Tianzhu, and he was born in Qiuci. When he was a teenager, he studied in the western regions and Tianzhu countries. Later, he entered Liangzhou and Chang ‘an, and tirelessly translated classics, making great contributions to the China of Buddhism. He became the first person in the cultural exchange between China and the West and the first of the four translators on the Silk Road before Master Xuanzang in the Tang Dynasty.

　 　 　 　"Pioneering" — — Kumarajiva’s life story runs through the whole movie. From Qiuci to Tianzhu countries, and then to the mainland of China, Kumarajiva witnessed the rich and diverse civilizations along the Silk Road, and also understood the necessity and importance of spreading the civilization achievements of the western regions and Tianzhu to the mainland of China at that time. As a result of Kumarajiva’s translation of classics in Chang ‘an, China’s classical philosophy system, religious system, artistic system and even ideological system were completely transfused. He not only laid a solid foundation for the China of Buddhism, but also integrated Buddhism with Confucianism and Taoism, which together formed the backbone of Chinese national ideology and culture in later generations. His translated works not only started the academic and practical development of China’s translation studies, but also provided reference for later generations’ prose, poetry, drama and novel creation. It has also played an important role in promoting the innovation and development of traditional art statues, painting art and architectural art in China.

　 　 　 　"Dedication" — — Since Qiuci entered Liangzhou, Kumarajiva endured humiliation, Do not forget your initiative mind, and strove forward. He actively learned about local customs and learned Chinese from local residents with an open mind, which laid a solid foundation for cultural communication and translation in the future. This great dedication is the spirit that the film focuses on and carries forward, and it will also be the focus of the film’s education for contemporary people.

　 　 　 　"Professional" — — The film focuses on the unity of academics, artistry and drama. Academic, refers to the professional standards required for the professional content related to history, philosophy, religion, language, etc., such as the use and presentation of ancient Sanskrit, Tuhuoluo and ancient Chinese in the film. In terms of artistry, the splendid cultural exchange achievements on the Silk Road, such as Qiuci music and dance, mural art and sculpture art, will be expressed. Dramatic, focusing on in-depth expression in all kinds of conflicts and challenges that have gone through thousands of difficulties and dangers.

　 　 　 　In addition, Gansu Film Bureau, Gansu Film Association, relevant cultural units in Shenzhen, and many domestic cultural units and cultural enterprises all sent congratulations and messages to the film, and gave full affirmation and support to the film.

The launch conference of the movie Kumarajiva.

　 　 　 　The film Kumarajiva is jointly produced by Shenzhen Zhengfa Film Co., Ltd., Gansu Silv Yijing Cultural Industry Co., Ltd., Shanghai New Culture Media Group Co., Ltd. and Beijing Kelaier Cultural Media Co., Ltd., and is expected to be released in 2023.

In 2003, highly pathogenic avian influenza (HPAI) broke out in Southeast Asia. Until recently, HPAI only broke out in Indonesia, Viet Nam, Thailand, Laos, Cambodia and China and other eastern Asian countries. But from April to June, 2005, more than 6,000 migratory birds died of H5N1 in Qinghai Lake, China. In July 2005, H5N1 outbreaks also occurred in Russia and Kazakhstan. In August, 2005, a wild bird died of H5N1 in a lake area in northern Mongolia. In October 2005, poultry or wild birds infected with H5N1 were also detected in European countries such as Turkey, Romania, Greece, Sweden and Britain. The H5N1 avian influenza epidemic broke out in Anhui, Hunan and Liaoning. This worldwide outbreak of avian influenza has caused a large number of poultry to be killed and infected people. As of November 2, 2005, 122 people have been found to be infected with H5N1, of which 62 died [1]. The worldwide outbreak of H5N1 highly pathogenic avian influenza has caused great losses to agriculture and aquaculture, posed a serious threat to human life safety, and attracted worldwide attention. The worldwide outbreak of HPAI can easily remind people of the role of migratory birds in the spread of avian influenza, because migratory birds have the ability of long-distance migration across national boundaries, and they are regarded as a major carrier of avian influenza virus. However, based on the existing facts, it is still difficult to determine the role of migratory birds in the spread of avian influenza.The outbreak of avian influenza in 2005 showed some characteristics different from previous outbreaks. The research work is still going on. Although the role of wild birds in the spread of avian influenza is still controversial, it is urgent to establish a monitoring network for wild birds and conduct a dynamic study on the epidemiology of avian influenza virus.

1 influenza virus characteristics

Avian influenza virus belongs to Orthomyxoviridae. According to nuclear protein (NP) and membrane protein (M1), it can be divided into three types: A, B and C. According to hemagglutinin (HA) and neuraminidase (NA), influenza A virus is further divided into subtype 2. Up to now, 16 HA (H1-H16) and 9 NA (N1-N9) influenza virus subtypes have been found, and H5N1 is one of the virus subtypes 3.

According to the pathogenicity, avian influenza viruses can be divided into HPAI and LPAI (low pathogenicity avian influenza virus). LPAI is often parasitic in the respiratory and digestive systems of birds, and generally does not cause pathological reactions, or only causes mild pathological symptoms. However, HPAI can infect various tissues and cells of the host, causing various organs of the host to fail, leading to death, and its mortality rate is as high as 100%. Up to now, all the HPAI found are H5 and H7 subtype influenza viruses. LPAI can be transformed into HPAI4 through the change of amino acid site in HA0 cleavage region.

Influenza A virus has been isolated from many animals, including humans, pigs, horses, seals and wild birds. The phylogenetic study of influenza A virus found that influenza A virus has host interspecific relationship, and other animal influenza A viruses originated from waterfowl influenza A virus 5.

The wild migratory birds themselves are the natural reservoir of bird flu.

All virus subtypes of 16 kinds of HA and 9 kinds of NA have been found in aquatic bird populations. Stakkknecht and Shane isolated 2,317 strains of virus from 21,318 birds, with a carrying rate of 10.9%, including 14,303 birds of the order Animalia, and 2,173 strains of virus were detected (15.2%). Except for geese and ducks, the carrying rate of influenza virus in other birds was only (2.1%) 6. It is worth noting that influenza A virus seems to have achieved an ideal parasitic adaptation in the host of wild birds. LPAI is parasitic in the digestive or respiratory system of the host. LPAI isolated from most wild birds is nontoxic, and the host has no symptoms or only mild symptoms. The transmission between birds can be directly or indirectly through dust, water, food and other pollutants contaminated by feces. LPAI may be transmitted to poultry through contact between wild birds and poultry, and mutate in poultry population, leading to HPAI. Poultry infected with HPAI can lead to systemic infection. Clinical symptoms include decreased egg production, dyspnea, excessive tears, brain edema, diarrhea and neurological symptoms that eventually lead to death. But so far, there is no more evidence to prove that wild birds are natural reservoir of HPAI. Therefore, there is a theory of HPAI outbreak mechanism that only when LPAI in wild waterfowl spreads to poultry such as chickens or turkeys, and LPAI mutates into HPAI in poultry, will it lead to the outbreak of highly pathogenic avian influenza. Since 1959,There were 19 incidents in which LPAI from wild birds was transmitted to poultry and mutated into HPAI in poultry, which eventually led to the outbreak of the epidemic.

3 Debate about Wild Birds as Spreaders of HPAI

It is precisely because wild birds are the natural reservoir of avian influenza virus, and the migratory route of migratory birds can obviously connect Asian countries with the outbreak points of H5N1 avian influenza in Siberia, Kazakhstan and Europe. Therefore, when HPAI was raging, some people suspected that migratory birds were spreading the bird flu virus. But so far, no clear source of H5N1 HPAI that ravaged Asia in 2005 has been found. It is speculated that before the outbreak of HPAI in domestic chickens in Hong Kong in 1997, LPAI, the predecessor of this kind of HPAI, might parasitize the wild waterfowl population in southern China and spread and evolve, and then contact with poultry in Hong Kong through some channels. LPAI mutated into HPAI and broke out in 2003. The Hong Kong government controlled the outbreak of bird flu by killing 1.5 million poultry. Then, in December 2003, the virus once again ravaged Korean chicken farms. Outbreaks in Japan and Vietnam in January 2004; An epidemic was discovered in Indonesia in February; It soon led to outbreaks in Thailand and China.

But many ornithologists doubt the hypothesis that wild birds infect avian influenza. First, since the late 1990s, the United States Department of Agriculture has detected tens of thousands of migratory birds migrating from Asia to Alaska, and Hong Kong researchers have also sampled thousands of inbound migratory birds, but none of these tens of thousands of wild bird samples have detected H5N1 subtype. Up to now, the research results show that the H5N1 strain that causes high mortality of poultry is also pathogenic to wild birds. Wild birds infected with HPAI will also get sick and die. When the host dies, the spread of the virus stops, and the spread chain of the virus is interrupted. Secondly, the transmission path and outbreak time of avian influenza are not very consistent with the migration path and migration time of migratory birds. Although wild birds are the natural reservoir of avian influenza, it is not entirely accurate to blame wild birds for the outbreak of HPAI. Because in addition to the migration of migratory birds, bird flu may be spread, the backward feeding methods of mixing livestock and poultry with wild birds provide an ideal environment for the mutation and breeding of bird flu virus, and human activities such as frequent poultry trade and wildlife smuggling may play an unimaginable role in the spread of the virus. For example, in January 2004, an outbreak of H5N1 occurred in Lhasa, Xizang, which was finally found to be caused by selling a batch of sick poultry from Lanzhou, Gansu, 1500 kilometers away to Lhasa. An even more surprising incident occurred in Brussels. In October 2004, two crested eagles smuggled into Belgium from Bangkok Bird Market were seized at Brussels Airport.And detected that it has been infected with H5N1 virus. Therefore, many biologists are skeptical about the hypothesis that migratory birds spread avian influenza virus.

While people are arguing about the role of wild birds in the spread of avian influenza, the H5N1 outbreak in 2005 showed several aspects different from previous epidemics. Until the spring of 2005, there had not been any death of wild birds infected with H5N1 virus. However, in April 2005, the H5N1 outbreak in Qinghai Lake killed more than 6,000 migratory birds. At present, researchers are still investigating the causes and possible consequences of the outbreak of H5N1 in Qinghai Lake.

Then in August, 2005, wild birds in Lake Irkher in Mongolia also died of H5N1 infection. There are few poultry farms in Lake Irhull. It is likely that wild birds infected with H5N1 brought the virus to Lake Irhull, and the US Department of Agriculture only detected H5N1 strains in dead birds, but not in other living ducks, gulls, geese and swans. It is not known which kind of birds spread the virus, which may be very difficult, because there is very little research work on avian influenza virus in other birds except waterfowl. While the research work is still in progress, in October 2005, several European countries in Caspian Sea, Black Sea and Mediterranean Sea broke out one after another, which made more and more people believe that wild birds played a role in the spread of avian influenza.

In October 2005, an outbreak of avian influenza occurred in Hunan, Anhui and Liaoning, and the state took decisive measures to control the epidemic. Some experts said that the epidemic focus may come from migratory birds 9.

4. Establish a wild bird influenza virus monitoring network and strengthen

Protection of wild bird resources

While the role of wild birds in the transmission of avian influenza is still controversial, Europe has begun to establish a European-wide investigation and monitoring network for wild birds. Researchers in the Netherlands have collected more than 6,000 bird samples on the migration routes of European migratory birds. The monitoring network is not only to study the role of wild birds in the spread of avian influenza, but also to monitor the changing direction of avian influenza epidemic, study the variation law of avian influenza virus, and provide valuable data for preventing the outbreak of avian influenza.

Because all the influenza strains in the history of human influenza outbreaks are new strains formed by the recombination of avian influenza strains and human influenza strains, it is difficult for human immune system to play a role in the face of this new strain, and it is difficult for vaccines based on unchanged strains to play a role in the new strain, so it is easy to trigger human influenza outbreaks, resulting in significant economic losses and human death. The wild bird influenza epidemic monitoring network can not only be used as an early warning network for human influenza outbreaks, but also monitor the variation direction of viruses, providing reliable data for vaccine development, and developing vaccine strains that may cause influenza outbreaks before influenza outbreaks, thus changing the previous practice that vaccines can only be developed after influenza outbreaks. In addition, this monitoring network can also monitor the changes of antiviral drug resistance of viruses for a long time to ensure the effectiveness of antiviral drugs in the emergency of influenza outbreak. At present, it has been found that avian influenza virus has developed resistance to interferents based on hemagglutinin (such as amantadine); The interferents developed based on neuraminidase mainly include Tamiflu produced by Roche and Rekenza produced by Gkaxo Smith Kkine. Recent studies have found that influenza virus has produced a few resistance to Tamiflu, while Rekenza has not found any record of resistance because of its low dosage. Therefore, governments around the world should pay attention to the problem of drug resistance while stockpiling antiviral drugs. Use the monitoring network to monitor the virus for a long time,The problem of drug failure caused by drug resistance can be found in time.

Therefore, it is of great significance to establish an influenza surveillance network for wild birds. In the face of severe avian influenza epidemic, China should immediately set up its own wild bird monitoring network, study the role of wild birds in the outbreak of avian influenza, find key hosts, study the transformation and variation law between LPAI and HPAI, monitor the direction of virus variation, and provide reference for vaccine development, and monitor the change of virus resistance, so as to provide reference for the development and storage of antiviral drugs.

5 conclusion

The role of wild birds in the spread and outbreak of avian influenza is still controversial. By analyzing the existing evidence, it is still impossible to confirm the role played by wild migratory birds in the spread of avian influenza. After more than one year’s molecular epidemiological investigation of avian influenza, although it has not been confirmed that wild birds are natural reservoir of HPAI, it can be confirmed that wild birds can be infected with HPAI H5N1 virus, not only migratory birds but also resident birds. All kinds of facts remind us that the outbreak and epidemic of HPAI H5N1 in the world may include the repeated transmission link of "wild birds → poultry → wild birds → poultry", and each host transfer and repetition may enhance the toxicity of the virus.

LPAI can mutate cyclically in poultry and wild birds until the HPAI epidemic occurs. HPAI virus is fatal to poultry and wild birds that originated in the first place. Infected wild birds are often dying or dying, which may affect their ability to spread the virus over a long distance. The fact that migratory birds in Qinghai Lake are infected with avian influenza reveals that H5N1 virus can spread among wild birds. However, these viruses are collected from dead or dying individuals, and they are the ultimate hosts. The further monitoring results of migratory birds that survived the bird flu control in Qinghai Lake will prove whether it is possible for migratory birds in Qinghai Lake to spread the virus with migration. At present, before we fully understand the role of migratory bird migration in the process of bird flu transmission, we should not blindly assume that HPAI has nothing to do with migratory bird migration, nor should we ignore the role of migratory bird migration in bird flu transmission. In addition, a very important point is often overlooked by everyone, that is, keeping birds. Previous studies mainly focused on migratory birds, and recently HPAI virus was detected in resident birds. If HPAI H5N1 can be isolated from a large number of healthy birds, it will be the biggest threat for human beings to prevent and control avian influenza.

From the perspective of logistics, environment and biodiversity, it is difficult to control avian influenza infection in wild birds at this stage. Indiscriminately killing wild birds is ineffective in preventing the spread of avian influenza, and it is likely to cause the extinction of wild birds.

In addition to paying attention to the role of wild birds in avian influenza, limiting the contact between poultry and wild birds should be a key part of avian influenza prevention strategy. We should reduce the contact between people, poultry and wild birds as much as possible, improve the level of poultry raising and avoid free-range; Strictly manage the poultry and wildlife trading market; Strengthen quarantine and immunization work; Put an end to illegal unlicensed poultry and wildlife trade.

In order to prevent the spread of HPAI, it is urgent to carry out scientific research on wildlife diseases. Establish a monitoring network for avian influenza in poultry and wild birds. Monitoring, sampling and analyzing the evolution and variation of avian influenza subtype virus in wild birds. Establish and improve the laboratory research ability to quickly detect and analyze the characteristics and types of viruses. Establish a perfect monitoring network of wild bird epidemic focus in order to quickly respond to virus emergencies and provide timely reference for national decision-making. Long-term monitoring and detection of avian influenza epidemic situation. Investigate the wild host distribution of avian influenza virus, study the variation law of the virus, determine the distribution, types and natural history of avian influenza virus in wild birds, and explore the relationship between wild migratory birds and agriculture and aquaculture structure and its role in the transmission of avian influenza virus to poultry and people. Develop and reserve safe vaccines and antiviral drugs against avian influenza virus. Organize veterinarians, wildlife experts, ornithologists, virologists, molecular biologists and other multidisciplinary experts to jointly study the changing law of avian influenza, fully understand the role of wild birds in the spread and spread of avian influenza virus, and prevent the outbreak of avian influenza and human influenza.

"Love without regret" special analysis of professional advantages to truly present the car to every detail

The racing scene of the movie "Pegasus 2" is exciting and shocking. Many viewers commented: "Watching racing on the big screen is exciting. Han Han must be the director who knows racing best!" The newly released special "Love Without Regret" focuses on Han Han, a screenwriter and director who has made many achievements as a racing driver. He used his passion for racing and his professional advantages in Pegasus 2, and he knew exactly what he wanted. Shen Teng believes that few people can have such professionalism as Han Han in the dual fields of racing and directing. Adam, on the other hand, revealed that Han Han has high requirements for racing movements, such as eye angle and movement range. As Marin, the director of Group B, said, "Because he is a racing driver, he not only looks at every shot from the perspective of a director, but also looks at every shot from the perspective of a racing driver." Han Han pursues the truth about the overall shape, interior, center console and other details of the racing car, and has made great efforts in every place. He is called "crazy about racing details" by Xue-hao Zhao, production designer. Norman Luo, the action director, also pointed out that Han Han also has high standards and strict requirements for racing pictures, "making every shot achieve the best effect".

In the movie, Zhang Chi’s love for racing also "echoed" with Han Han. When talking about the continuation of the speeding story, Han Han confessed his preference for Zhang Chi, hoping to continue the fate of this character and present a story that he was covered in scars and suffered injustice but did not change his love. When creating the scene in which Zhang Chi met himself five years ago, Han Han also thought about what Zhang Chi would say to himself. Finally, he felt that he didn’t need to say anything, and it was enough for him to give his present self an affirmation to carry on. I believe the audience can feel the firm love of Han Han and Zhang Chi besides being shocked by the high-energy and high-burning racing scene.

The footage of the feature film "Rushing in the Blizzard" is thrilling. Zhang Chi is not afraid of the snow sprint to detonate the cool mood

The Bayinbuluke Rally shown in the movie "Pegasus 2" not only has a cool shock from the audio-visual level, but also has a strong appeal from the inner level of the characters. The feature clip of "Running the Line in the Blizzard" is one of the highlights that make countless audiences excited, and the line "I have tried countless times, but the opportunity will only appear once or twice" that resonates strongly also comes from it. Zhang Chi came back from five years’ dormancy and drove, but he had to face the extreme weather at Bayinbuluke Rally. The storm and hail brought a series of problems, such as sudden drop in temperature, slippery road surface and blocked sight, which made the danger soar. However, rally was originally designed to challenge all kinds of natural conditions, and all racing cars and drivers were born for it. Zhang Chi didn’t want to miss this hard-won and last Bayinbuluke Rally. Although his car was not ready and his physical fitness was not as good as before, he still chose to face the difficulties. With superb technology, rich experience and persistent belief, he flew all the way without fear of snow and ice, and finally completed the difficult "Scandinavian pendulum" with the help of the navigator Sun Yuqiang and rushed out of the snowy road. This scene set off an extremely cool mood, which made countless audiences admire it. They all said, "It exploded, and tears filled their eyes." "Zhang Chi sprinted in the snowstorm, and my palms were all sweaty." "I walked through the snowstorm and got rid of all obstacles.Live up to love and surpass yourself, really burning and moving. "

The audience of Chengdu roadshow called the film "Laughing and Burning" Han Han Adam Sean shared the moment of touching tears.

On the fourth day of Lunar New Year’s Eve, screenwriter and director Han Han, actors Adam and Sean appeared in the chengdu railway station activity of the national roadshow "Fill up the tank and fly all the way". The audience at the scene expressed their feelings of watching movies, saying that "the movie is particularly beautiful, laughing, refreshing, burning and exploding", "very passionate and very bloody" and "I hope I can bravely overcome the difficulties in life like Zhang Chi. There are also viewers who bluntly cried several times. After finding the lead seal, Zhang Chi said that he only wanted innocence, and when he looked at himself five years ago, he said, "I can hold on, Zhang Chi" and other plots were burning, moving and inspiring.

When asked about the moment when he was moved to tears in the movie, Han Han revealed that it was the scene where Zhang Chi overturned in the driving school late at night, and shared the behind-the-scenes story. At that time, he filmed for several nights. Shen Teng had just finished surgery and needed to hang Weiya upside down. Moreover, it was an emotional outburst scene in Zhang Chi, which was difficult to shoot. While shooting, he was worried about Shen Teng’s physical condition, and he could not even tell whether Shen Teng was in pain or performing Zhang Chi’s pain. Adam was deeply impressed by the scene in which Li Xiaohai saved Zhang Chi: "Brother Teng finally laughed, which may make everyone laugh, but I feel more bitter about Zhang Chi. It’s not easy to see him these years. "Sean frankly was deeply moved by many lines of Zhang Chi’s race, especially the dialogue" We all know that this car is not ready "and" But I am ready ".He was not at the scene when shooting this scene, and heard Zhang Chi say this sentence on the big screen." I was really moved to tears at that moment ". In addition, many spectators came prepared. Adam was presented with a banner of "Young Actor Adam, Flying on the Road Forever", and he and Sean’s characters Li Xiaohai and Liu Xiande were nicknamed "Looking Awesome" group. The founders also received a local special food, Farewell Chicken, and there was a lot of joy on stage and off stage.
