　　Developing autonomous driving technology is an important content of building a transportation power. In recent years, with the rapid development of new technologies such as artificial intelligence, 5G and big data, the application of autonomous driving technology in the field of transportation has been accelerated, and the rapid iteration from closed site testing to road testing and from pilot demonstration to commercial trial operation has been realized.

　　The Ministry of Transport recently issued the "Guide to Transportation Safety Services for Self-driving Vehicles (Trial)" (hereinafter referred to as the "Guide"), which made it clear for the first time from the national policy level that intelligent networked vehicles can be used for transportation business activities, and pressed the "acceleration button" for the commercial application of self-driving technology in China.

　　What is the development of autonomous driving technology at present? How to improve the safety guarantee ability of autonomous driving? The reporter interviewed the relevant person in charge of the Ministry of Transport and relevant experts.

　　The market scale is growing rapidly, and it is steadily moving towards commercial application.

　　"With the joint efforts of all parties, in recent years, China’s autopilot-related industries and market scale have shown a rapid growth trend, and autopilot technology has steadily moved from testing and demonstration to commercial application." Zhang Jinhua, chairman of China Automotive Engineering Society, introduced.

　　The industrial development environment continues to improve. At present, 17 national-level test demonstration zones, 7 national-level vehicle networking pilot zones and 16 "Shuangzhi" pilot cities have been built nationwide, with a cumulative open test road of over 22,000 kilometers and a cumulative test mileage of over 70 million kilometers. Beijing, Shanghai, Guangzhou, Shenzhen and other cities have introduced policies to allow self-driving cars to engage in commercial trial operation of urban public buses, taxis, logistics and distribution in specific areas and at specific time periods, and the application scale has been expanding.

　　In Shunyi District, Beijing, hundreds of bright yellow automatic delivery vehicles appeared in the streets and lanes, waiting for traffic lights side by side with pedestrians, or avoiding other vehicles safely on the road. "After years of iterative upgrading, unmanned delivery vehicles can not only ‘ Get ’ , can provide consumers with ‘ Send it quickly ’ Service experience. " The person in charge of the automatic delivery department of Meituan said that at present, in Shunyi, the daily delivery orders of automatic delivery vehicles of Meituan have reached thousands.

　　In the Economic Development Zone of Wuhan, Hubei Province, open the "radish run" taxi software, and you can quickly call an unmanned self-driving car by setting the starting point and the ending point. Passengers click "OK" on the back screen, and the vehicle can travel according to the established route. "The fisheye camera and laser sensor on the roof device can help the vehicle avoid obstacles accurately and automatically adjust the speed according to the road conditions." According to the person in charge, 300 driverless cars have been put into operation since the unmanned self-driving travel service was opened in Wuhan in August 2022, covering a population of over 4 million.

　　The application of industry innovation has accelerated. Scene-level autonomous driving solutions have accelerated to maturity, and some autonomous driving products have reached the conditions of mass production application, and have been applied to transportation service scenes such as urban travel and freight logistics on a certain scale, and new formats such as autonomous parking service and unmanned distribution have emerged continuously. At present, there are more than 200 self-driving city buses, more than 1,500 self-driving taxis and about 1,000 self-driving trucks in China. Baidu Apollo autopilot test has a total mileage of more than 78 million kilometers, and its travel service covers more than 10 cities.

　　With the continuous expansion of market scale, it is urgent to strengthen industry norms. "At present, the basic requirements for using self-driving cars for transportation operations are still unclear, which is not suitable for the healthy and orderly development of self-driving cars, and the safety pressure is increasing." The relevant person in charge of the Transportation Service Department of the Ministry of Transport said that the Guide clarified the basic requirements for using self-driving cars to engage in transportation business activities under the framework of current laws and regulations, and guided the healthy development and standardized application of self-driving cars in the field of transportation services in an orderly manner while ensuring transportation safety.

　　Build a security system to provide compliance for business activities.

　　Transportation services are related to the national economy and people’s livelihood. Continuously improving the safety and security capability is the primary goal of transportation services, and it is also the basic requirement for the promotion and application of self-driving cars in transportation services. Sorting out the measures in the Guide, the word "safety" runs through.

　　"Adapting to the development trend of autonomous driving, the Guide focuses on ensuring the transportation safety of autonomous vehicles. Under the condition of meeting the requirements of relevant departments for the access and road traffic of autonomous vehicles, it puts forward requirements for the production conditions and qualifications of transportation operations, dynamic supervision and emergency handling of vehicle operation, and operational supervision, and guides the transportation safety services of autonomous vehicles in all directions and in the whole chain." Zhang Jinhua said.

　　In terms of technical standards, the Guide clarifies the technical requirements for self-driving cars, emphasizing that "self-driving cars engaged in taxi passenger transport, road passenger transport and road cargo transport should also meet the requirements of technical standards for operational motor vehicle safety in the transportation industry". "This move has achieved the connection with the management boundary of self-driving cars in the departments of industry, information and public security." Li Bin, vice president of the Highway Research Institute of the Ministry of Transport, said.

　　In terms of personnel allocation, the Guide specifically puts forward the concept of "safety officer" in view of the safety problems during driving.

　　"The on-board driver or operation safety guarantee personnel of the self-driving car is ‘ Safety officer ’ 。” Li Bin said that the Guide fully considers the business models of self-driving transportation with different formats, and provides for the allocation, skills and qualification requirements of safety officers engaged in different transportation business activities by classification on the premise of ensuring safety. Among them, in view of the application scenario of fully self-driving cars engaged in taxi passenger transport, the form of personnel support for remote safety officers is put forward in particular, and it is clear that "with the consent of the people’s government of the district and city, remote safety officers can be used when operating in designated areas, and the ratio of people to vehicles of remote safety officers should not be less than 1: 3".

　　"Overall, the Guide has built a safety guarantee system from six aspects: safety production system, transportation safety guarantee, running state information management, vehicle dynamic monitoring, safety notification and emergency response." Li Bin believes that under the premise of being consistent with the current road transportation management, the Guide fully combines the new characteristics of self-driving car transportation, and provides compliance for self-driving cars to engage in road transportation business activities safely.

　　Classified scenarios provide normative guidance to accelerate the application of technology.

　　As a new technology, autonomous driving has been widely used in various transportation service scenarios. Different scenarios have different design and operation conditions, different security risks and different risk level requirements. In order to further ensure safety, "classified policy" has become a highlight of the Guide.

　　The Guide clarifies the application scenarios of self-driving cars to carry out road transport services. For urban public buses and trams, related passenger transport business activities can be carried out under the scenes of physically closed, relatively closed or simple road conditions with fixed lines and controllable traffic safety; For taxis, passenger transport business activities can be carried out in the scene of good traffic conditions and controllable traffic safety; At the same time, self-driving cars are prohibited from engaging in road dangerous goods transportation business activities. At the same time, the Guide clarifies the requirements for "self-driving transport operators", and taxi passenger transport and road passenger transport should be insured with carrier liability insurance according to law.

　　"Standardizing the application of self-driving cars in the field of transportation services by classification, scene and level will effectively guide all kinds of transportation service business activities to carry out self-driving applications, effectively ensure the safety of self-driving transportation services, and promote the healthy and orderly development of commercial applications of auto-driving." Wang Advanced, vice president of the Research Institute of the Ministry of Transport, said.

　　The overall scale of China’s automobile industry remains in the forefront of the world, and the production capacity and application technology level have been greatly improved. As an important breakthrough to improve the level of industrial intelligence, autonomous driving has been valued and supported by relevant departments.

　　In 2020, the Ministry of Transport issued the Guiding Opinions on Promoting the Development and Application of Road Traffic Autopilot Technology; In 2021, the Ministry of Industry and Information Technology issued the Opinions on Strengthening the Access Management of Intelligent Networked Automobile Manufacturers and Products; In November 2023, four ministries and commissions, including the Ministry of Industry and Information Technology, issued the Notice on Launching the Pilot Work of Intelligent Networked Vehicle Access and Road Access, which covered the key links of vehicle use, such as production access and road management of automobile products, and the management policies for the production and use of self-driving vehicles were gradually established … … In recent years, various ministries and commissions have accelerated the research on policies related to the commercial application of autonomous driving and issued a series of policy documents.

　　"The increasingly perfect industrial development environment has made it possible for self-driving cars to accelerate their application in transportation services." Wang Advanced said that the release of the Guide has established a safe bottom line for the application of self-driving cars, and also left enough room for the innovative application of autonomous driving, which will further promote the application of autonomous driving technology in the transportation field.

On September 4, 2019, The Lanxin Grand Theatre premiered at the Venice International Film Festival, which was the first time that Hong Ying, the author of the original novel Death in Shanghai, saw the film twice a day.

Writer Hong Ying commented that "Lanxin Grand Theatre" filmed the original content of the novel, and also photographed something that sank at the bottom of the text. It is a film."Pure art film with spy war shell", at the same time, is a."Pure feminist film".

Feminism, which is what Lou Ye is most interested in "Death in Shanghai". From the original work to the film, feminism is a personal choice finally made by Yu Yan under the influence of the times, and it is the sharp knife that Baiyun Shang stabbed Mo Zhiyin’s lower body.

However, Hong Ying’s fascination with Shanghai and her concern for women make her attach great importance to the restoration of time. Even in Lust, Caution by Ang Lee, she is not satisfied with the background and characterization. But Lou Ye didn’t slack off, so there was the "island" Shanghai in "Lanxin Grand Theatre". In the eyes of Hong Ying, "Lou Ye was born for movies, and it is important to regard movies as the first thing in life.He is not sociable and saves more time to study movies. “

Going to the cinema in Lou Ye always makes people nervous, and the shift of "Lanxin Grand Theatre" seems to be expected. After nearly three years, it finally meets the audience. butLou Ye and Hong Ying, who have known each other for many years, began to cooperate in the 1990s, and it was not until the Lanxin Grand Theatre nearly 30 years later that the interweaving of words and images was completed..

　01　　　　　

Shanghai, Shanghai

The death of Shanghai, pun intended.First, the opening part reveals the tragic ending of the heroine Yu Yan jumping from the top floor of the international hotel, leaving no room; The second refers to the city of Shanghai, which has fallen into"Double Death"In the middle.

"In the deafening sound of guns, Shanghai was swallowed up piece by piece. Sad cries come out of underground water holes and linger in the air. "In Hong Ying’s description, Shanghai was" dead "in the process of building a strong ship and sharpening its guns; However, "the mountains and rivers are broken, and the citizens are more addicted to pleasure … even if the land in Shenzhou is sinking … people on the isolated island are more drunk than before … Shanghai has become a freak in the war … China may survive, but this Shanghai is hard to survive", which is its second death.

In Lan Xin Grand Theatre, Tan Na, the director played by Mark Chao, directed a play and invited Yu Yan, played by Gong Li, to return to Shanghai from Hong Kong to play the heroine. The play is called.Saturday novel. This play is adapted from the novel Shanghai by Japanese writer Yokomitsu Liyi. The work describes the May 30th Movement in 1925, and Lou Ye changed the story of "romantic affairs" in the original work into a tragic tragedy. The English title of "Lanxin Grand Theatre" directly uses "Saturday Fiction", which is very obvious.

One is Shanghai in the war years. The protagonists in the film are all intellectuals and artists. They go in and out of hotels and theaters and live a decent and prosperous life for the middle class. In the play, it is a more real story of the left-wing bloody struggle. Lou Ye admits that this is a class supplement to the main story; In addition, Lou Ye has also set up two important scenes, one is a prostitute warming herself outside the hotel, and the other is a laundry and ironing lady in the hotel, so that we can get a glimpse of a more three-dimensional Shanghai.

The second is to show the cowardice and powerlessness of the left-wing director Tan Na. He hopes to be a revolutionary like Yu Yan, but as an artist, his body retreats in the face of violence, and he can’t reach the front line, so he can only support the workers’ movement through drama. He was forced to get involved, as he himself said, he was a pawn, butIn this life-and-death war, who is not a pawn that has been used and sacrificed?

Lou Ye played the role of the play to the extreme, and his deeper intention was to criticize the "Saturday School". "Saturday School" is a literary school in the early years of the Republic of China. It is the aftermath of "Yuanyang Butterfly School", a replica of Crescent School, and an interesting literature that promotes games and recreation.

At that time, Tan Na’s left-wing troupe was in opposition to Saturday School, but Lou Ye used a left-wing director to direct a drama called Saturday Novel to tell an anti-imperialist strike of workers, in which the irony was concrete and brilliant.In the current context, isn’t this an accusation against frivolous mainstream entertainment and the supremacy of pleasing?

Although "Lanxin Grand Theatre" is a black-and-white film, it is a color film in Lou Ye’s view, because he thinks that the workers’ strike situation explained in "Saturday Novel" is "Chromatogram of Shanghai in 1941",remove the surface color, the gray level between black and white needs more rigorous treatment.

In the black-and-white presentation, Lou Ye used the consistent hand-held lens to "shake" the uneasy environment and the confusing fate of the characters, and extended the inner world of the characters to history and politics to complete the real expression. Therefore, Lou Ye expressed his sympathy for this "isolated island" in his way, even though he didn’t spend too much time on the urban landscape of Shanghai.

Yu Yan, Qiu Lan

"At sea, the lighthouse does not exist in the darkness for a person. Butterflies fly freely, which is actually the same fate as being a specimen. But in the process of flying, no god can dominate this fate. "

Hong Ying, a writer, regarded this passage in the original work as a key to open this story. She privately thought that the lighthouse was the spark of revolution, while the butterfly was a woman in troubled times like Yu Yan. This passage implied their unknown fate, and at the same time, they could make rational judgments independently and their free will was not bound.

In Shanghai in December, the dark clouds were overwhelming and the rain was complicated. This rain has been falling from the original book to the film, which is a painful note behind this seemingly glamorous city. In the film, Yu Yan returned to Shanghai in the heavy rain. The "panic" lens swept through the cold and damp, capturing her tightly wrapped face. The flash of the reporter’s camera was like a lightning bolt that cut through the darkness, indicating that her return was doomed.

From then on, she had two names, one was Yu Yan, who was well known, and the other was Qiu Lan, who led the workers’ strike in the drama.At the same time, she has multiple identities, such as star, spy, ex-wife, lover, daughter and woman, which makes her have to be watertight in front of others and treading on thin ice behind.

Hong Ying mentioned that "spy plays are mostly literary plays, and knives are used at most", while spy missions are the front lines in the battlefield behind enemy lines. In this wrestling field where multiple forces are mixed, everyone’s face is vague, but everyone with tasks is as agile as an eagle.The charm of Lou Ye’s "shaking" lens is that everyone who is deeply involved in it can’t see the overall situation, and the audience doesn’t have God’s perspective, but you can always feel the weight of a sharp eye in those flashes of focus.

But Yu Yan is not a cold-faced killer, nor does she rely on selling her beauty for information. In the film, from seeing Ni Zeren, the detained ex-husband, to hugging Tan Na after being forcibly photographed by the Japanese army, to hypnotizing Japanese intelligence officer Tanya Saburo, and the decisive battle on Saturday night, Yu Yan cried four times, without crying, all silently, letting tears flow on her face.

The next morning after she hypnotized Bai Yunshang, Bai Yunshang knelt beside her and leaned her head on her chest. After Tan Na stopped the Japanese from taking a photo, he buried himself in her shoulder. Compared with lust, the author sees more powerful and affectionate motherhood, which may benefit from Gong Li’s own charm, because Yu Yan in the original book is only 27 years old and does not have this weathered beauty.

The image of rain is like violet’s wet face, and the tears gush out again before they are dry.In the torrential rain on the night of the decisive battle, the literary drama set the stage, and the martial arts drama ended. Yu Yan pulled out her gun and walked alone in the Lanxin Grand Theatre. She knew that she was going to be a butterfly that was made into a specimen, so she shed tears and shot at the same time, and reason was not dominated by compassion.

On the other hand, in order to force the United States, which is on the sidelines, to show its position, her free will finally made her choose to "betray" her faith (adoptive father) for greater justice, and at the same time, she chose to go to more specific love when she could get away with it (Tan Na).This is a sacrifice, but also a double suicide.. This is the complete embodiment of modernity in pansy.

Lou Ye, the movie.

In the face of Lou Ye’s films, what is certain now is that he is not afraid of no audience.

At first, Lou Ye seems to have had doubts about his market appeal.

In 1993, the first film "Weekend Lover", which took more than 40 days to shoot, was finally released on a small scale at midnight on weekends after two years of review. Shanghai first appeared in Lou Ye’s lens through "Weekend Lovers".

Censorship, underground, is the shadow attached to Lou Ye’s films from the beginning.

Frustrated, Lou Ye couldn’t escape the confusion of the dislocation between art and business: "It is becoming more and more difficult to decide whether antonioni’s film or Jackie Chan’s" The Red Fan District "is closer to the essence of the film."

A film that can’t meet the audience, part of its meaning will be dissolved. Perhaps it is to realize this, or it is the pressure of reality. Lou Ye turned to the system and filmed a thriller suspense movie "Girl in Danger", soLou Ye has never rejected commercialization, but he always "smuggled goods" under the framework of genre. Even today, if the concepts of stream of consciousness, vanguard and artistry are put into commercial genre films, not many viewers will buy it.

After several searches, Lou Ye came to Suzhou Creek, focusing on Shanghai again. On the oldest black and smelly water body in China, the love story of Motor and Peony was born from Lou Ye’s Super 8 camera.

Then came the 30-million-yuan production of Purple Butterfly, and on the eve of the outbreak of War of Resistance against Japanese Aggression, Shanghai merged into the faces of Zhang Ziyi and Liu Ye; Then came Yu Hong, the Summer Palace became synonymous with prohibition, and Lou Ye began to become a "fighter" in everyone’s mouth.

"Confusion and trial and error of intellectuals in social transformation" is the state of the characters in the film and a portrayal of Lou Ye himself, but is he really that confused? Not necessarily. In 2014, the poster of "Massage" was impressively printed.The slogan "Individual travelers should do it" is the insistence of the characters in the film, and it is also the reference of Lou Ye’s loyalty to himself in reality.

From the beginning to the present, he has never given up his pursuit of image style and personal expression. In terms of commercialization and artistic presentation, he has long been able to make a clear distinction: "Cooperate as much as possible on the bottom line and resolutely quit under the bottom line. I try to be happy. "

In front of Lou Ye, there are only movies, and in his eyes, movies are not just about telling a story.

The city is always Louyedian.Shadow business card,Magic Shanghai, lost Beijing, shaky Wuhan, turbulent Guangzhou, Lou Ye’s lens carved a landmark full of emotions. He once said: "The city is the skin of the film, and it is best to be combined with the story and have uniqueness."And it is always people who are placed in the foreground of this huge background board.It’s motor and peony, Yu Hong, Yu Yan, and what surrounds them is the torrent of the times and the historical process.

At the same time, Lou Ye is still exploring the audio-visual and structure.

Lou Ye has publicly expressed his disappointment with Rome directed by Alfonso Cuarón. He thinks that the black-and-white image of Rome is too exquisite and beautiful. "Then a film about the proletariat uses a completely bourgeois image.". When he came to Lanxin Grand Theatre, Lou Ye broke the exquisiteness of the picture with rough images that he was always good at. At the same time, he dispelled the bourgeois tendency of the film by supplementing the class and satirizing the "Saturday School".

Structurally, Lanxin Grand Theatre makes the play in the play to the extreme, allowing the audience to "magically" shuttle between reality and illusion, but if you are careful enough, you will find that Tan Na’s glasses are the password to unlock this magic. Structural addition to linear narrative and "blank space" in narrative through a large number of skipping clips greatly increase the richness of the story.

Looking back, this is just a story from Monday to Sunday, from the day of return to the night of decisive battle.Subtitles constantly remind the audience of the urgency of time like flipping through a calendar, but the "effective information" of the spy war action is not directly fed to the audience, and the audience needs to disentangle themselves from the struggles, passions and secret fragments of the characters.

So, this is just Lou Ye once again. "In the name of typology, do the opposite of typology."that’s all,This is the threshold of Lou Ye’s films. When you no longer regard the text as the first essence of the film, and regard the form and content as a narrative whole, audio-visual language is no longer an auxiliary expression, and at the same time capture the ideographic meaning outside the narrative, you will truly become his audience.Lou Ye once said: "You can believe it, because it happened in my lens;" You can also not believe it, because there are other things happening outside the camera lens. "

Lou Ye is not a fighter, he is just a film writer."Lanxin Grand Theatre" In the end, when the Japanese army broke into the stage with guns, the protagonist was in crisis, and the drama and reality were highly coincident in an instant. This is the art of violence intervention. We didn’t know the danger was coming until the stray bullet hit the audience.

Lou Ye said:All narratives of history are narratives of today.This is the modernity of Lanxin Grand Theatre.

IT House reported on March 18th that LinkedIn, a social platform for the workplace, was developing a built-in game function. Nima Owji, an application researcher, posted a series of screenshots on X, showing some games being developed by LinkedIn, and said that employees’ scores would affect their company’s ranking in the game.

LinkedIn has confirmed this plan to foreign media TechCrunch. The official said: "We are adding puzzle-based games to the LinkedIn experience to release some fun, deepen relationships and hopefully stimulate opportunities for dialogue."

The report also said that the games currently being developed by LinkedIn include Queens, Inference and Crossclimb. It is not clear when the game function will go online and whether it will be available to free users.

LinkedIn revealed that its advanced subscription plan in 2023 generated revenue of $1.7 billion (Note of IT House: currently about RMB 12.24 billion). These plans start at $39.99 per month (currently about RMB 288).

　　Air China flight CA1524 flew normally today (July 11th) after the clear sky turbulence, but the aircraft type changed.

　　The Paper reporter learned from Fei Changzhun platform that on July 11th, Air China flight CA1524 will still fly normally, and it is scheduled to take off from Shanghai Hongqiao Airport at 14: 45, and it is expected to land at Beijing Capital International Airport at 16: 36, with Boeing 747-89L.

　　On July 11th, China International Airlines issued a notice in its official Weibo: On July 10th, 2023, Air China flight CA1524 (Shanghai-Beijing), model A330-300, was suddenly bumped by the clear sky during the flight, and the crew and crew handled it according to the procedures, making every effort to safeguard the safety of passengers, and one passenger and one flight attendant were injured in the process. The flight landed normally at 17: 18, and Air China arranged a special person to accompany the injured passengers and flight attendants to the hospital for treatment.

　　Air China official micro-release notice Weibo screenshot

　　On the 11th, the band @SummerVapour Summer Solstice Dream released Weibo, saying that he was on flight CA1524 at that time, and he personally experienced the thrilling scene of the plane bumping. According to its profile in Weibo, SummerVapour Summer Solstice Dream Band consists of three people.

　　At noon on the 12th, Weibo replied to the The Paper reporter that the passengers were blinded at first when the plane was bumpy, and only after the plane was stable did everyone slow down and start looking for things, and young people helped the elderly with mobility difficulties. "Thanks to Air China flight CA1524, the professional crew, and the passengers who abide by the regulations, everyone was surprised and had an unforgettable flight."

　　In addition, Weibo also shared some warm-hearted clips at the time of the incident. After the turbulence, the crew broadcast for medical practitioners. The fans of star @ Kid-Lil Ghost had medical qualification certificates, and stood up first to help the injured passengers. When landing, @ Boxing World Li Jingliang soothed the passengers around and took everyone to applaud the crew. After landing smoothly, the musicians of various bands on the plane got up and squatted to help some people with mobility difficulties find lost mobile phone headphones and other items.

　　This incident has caused many netizens to pay attention to the word "clear sky bumps".

　　According to @ Central Meteorological Observatory, clear-sky turbulence usually occurs on sunny days, which is caused by clear-sky turbulence. Turbulence is caused by the irregular flow of the atmosphere. When encountering turbulence, the plane will bump rapidly, and in severe cases, the plane may temporarily lose control. Because it is not accompanied by obvious weather phenomena, it is difficult to observe and detect, which poses a great threat to flight safety.

　　According to the Beijing Evening News, in June, 2017, China Eastern Airlines flight MU774 from Paris to Kunming, China, also had a clear sky bump, causing dozens of passengers on board to be injured to varying degrees. At that time, Wu Mingxiang, a senior captain of Shenzhen Airlines, said: "We can only make a comprehensive analysis of the forecast through the high-altitude weather map before taking off, but the accuracy is low. In fact, flying to an area that may be bumpy is not necessarily bumpy, and it is also related to the flight altitude, so ‘ The clear sky is bumpy ’ It is not easy to predict. It is recommended that passengers fasten their seat belts when sitting in their seats. After all, the flight situation is complicated. Planes are different from cars, and the impact force before and after is not as big as that up and down, so wearing a seat belt can prevent people from flying and being injured. Generally speaking, people who are injured by bumps in the air are not wearing a seat belt. "

　　According to a recent report by Xinhua News Agency, a British study shows that in recent decades, the probability of aircraft encountering clear sky bumps during flight is increasing, which is inseparable from global warming under climate change.

　　Chen Jianguo, a senior pilot, told The Paper that there is no need to panic excessively in the event of bumps. Remember that keeping your seat belt fastened on the plane is the safest preventive measure, regardless of whether the seat belt indicator is on or not.
