Looking closely at "Made in China" through Shanghai Auto Show, US media: In the field of electric vehicles, China manufacturers play the leading role.

[Global Times Comprehensive Report] "The exhibition halls of dozens of China brand electric vehicles are surrounded by visitors, and the neighboring areas are full of foreign brands of gasoline-powered vehicles, but almost no one takes a look." The New York Times’s report on 20th described a strange phenomenon at the Shanghai Auto Show. As one of the largest auto shows in the world, this year’s Shanghai Auto Show is the first auto show of its kind in China since 2019, attracting more than 1,000 companies to participate. Throughout the world’s major auto shows, local enterprises are the absolute protagonists of the exhibition, and also represent the influence of a country’s auto industry on the world. With China’s car-making industry chain being pushed to the forefront of the world with the new energy revolution, the Shanghai Auto Show is becoming a showcase of "Made in China" in the automobile field. The New York Times reported that this year’s auto show showed a very clear signal: in the field of electric vehicles, manufacturers in China are playing the leading role.

Independent brands are attractive.

The Global Times reporter saw at the auto show that compared with previous domestic auto shows, the self-owned brands participating in this year’s Shanghai Auto Show are more and more attractive, and the product prices are more and more "bold". Almost every company has launched models with prices as high as hundreds of thousands or even millions of yuan, which has attracted much attention.

BYD brought its high-end brand "Looking Up" to the U8, the first production model, with a pre-sale price of 1.098 million yuan. This new energy vehicle, which focuses on hard-core off-road, is based on two core technological achievements-the power system driven independently by four motors and the intelligent hydraulic body control system. Another brand of BYD Tengshi exhibited the first edition of the medium and large five-seat hunting SUV N7 and Tengshi D9. Weilai ushered in the appearance of the new ES6 and 2023 ET7 at the auto show. The prices of the above models are almost above 300,000 yuan.

Traditional car companies are not weak. Hongqi appeared in two new energy products-Hongqi E202 and Hongqi E001. SAIC exhibited more than 130 new cars from six vehicle manufacturers, of which new energy vehicles accounted for nearly half. Geely brings its krypton series products. Great Wall Motor exhibited new energy vehicles such as Haval Xiaolong MAX, Wei brand Lanshan DHT-PHEV, and tank 500 PHEV, as well as the 6×6 super off-road platform of the Great Wall Gun which can carry a variety of power. Chery brought the first high-end intelligent pure electric car E03 from Starway, and Changan Automobile brought the deep blue S7 and the deep blue SL03.

"Visitors to the Shanghai Auto Show are amazed at the China brand." German "Der Spiegel" magazine said on the 20th that China car companies, which were often laughed at in the past, have already caught up and are moving towards the leading position. China automobile brands participating in the auto show have never been as wide-ranging and high-quality as this year-no matter big companies like BYD, Geely, Great Wall and SAIC, or start-ups like Weilai, beautiful shapes, charming atmosphere and breakthrough technologies can be seen everywhere.

Global Times reporter observed that executives and engineers of multinational car companies also appeared on the booths of China car companies. They are very concerned about the cutting-edge electrification technology exhibited by China car companies. As soon as the reporter entered the 6.1 Hall where China brands gathered, he saw a foreign engineer carefully studying the products of a Chinese lidar company. At the Great Wall Motor booth next to it, the reporter witnessed a number of foreign exhibitors exchanging business cards with booth staff.

China’s electric vehicle industry chain is leading the world.

"Local manufacturers are overtaking German brands in the electric vehicle market in China." Germany’s "Daily" reported on the 20th that at the Shanghai Auto Show, Volkswagen continued to appear as the leader of the world’s largest auto market. However, on the opening day of the auto show on Tuesday, news came that had a far-reaching impact on the industry: in the China market, BYD, a China manufacturer, surpassed the traditional leader Volkswagen in the first quarter. In the opinion of experts, German automotive engineers have become focused on studying the gap size of parts and body adjustment because of their success in the past decades, and are unwilling to take the initiative to meet the changes. But a quarter of all new cars sold in China are electric cars, and this trend is still rising.

At this auto show, Japanese car companies such as Toyota, Honda and Nissan have released new models to attract consumers in China. The Japanese news agency said on the 18th that the popularity of electric vehicles among China car companies is high, while the presence of Japanese car companies, which started late in the field of electric vehicles, is declining, and it is approaching a critical moment.

Japan’s "Daily News" said on the 20th that Japanese car companies are struggling in the field of electric vehicles. In 2022, Toyota sold 10.48 million new cars, ranking first in the world, but only 20,000 electric vehicles were sold. Toyota’s share of electric vehicles in the world is only 0.3%, far inferior to Tesla and BYD. The most worrying thing is that Japanese cars are gradually regarded as "outdated" by China consumers. A 29-year-old office worker in Beijing said, "The durability of Japanese cars is good, but the intelligent service in the car is insufficient." "Daily News" said that Japanese car companies started late in the field of electric vehicles, which also affected the intelligence in the car.

"It turns out that we have always said that China’s auto industry’ wakes up early and gets up late’, but on the new track of electrification, especially intelligent electrification, China enterprises are innovative in the whole industry chain, and their actions are more rapid than those of foreign enterprises." Fu Yuwu, honorary chairman of China Automotive Engineering Society, told the Global Times reporter that overall, the whole industrial chain of electric vehicles in China is in the leading position in the world.

Professor Ferdinand Dudenhoff, director of the German Automobile Research Center (CAR), who is known as the "godfather of automobiles" in Germany, said in an interview with the Global Times on the 20th that the achievements and technologies exhibited by China enterprises at the Shanghai Auto Show were impressive. On the one hand, intelligent cockpit and interconnection, on the other hand, products related to autonomous driving, and then battery technology, the automobile world is changing much faster than some people think. China is playing an increasingly important role in market scale and technology.

Baidu Apollo held an automobile intelligent conference on the eve of Shanghai Auto Show, released a brand-new upgraded product matrix of driving chart, and released "Baidu Intelligent Driving Open White Paper", which opened four key capabilities for automobile enterprises. Also on the eve of the auto show, Tencent demonstrated its technology and product system in the field of "Che Yun Integration" on the technology open day. In terms of battery technology, Contemporary Amperex Technology Co., Limited officially released condensed batteries during the auto show. It is understood that the energy density of the battery monomer can reach up to 500Wh/kg, which has the characteristics of high specific energy and high safety, and has mass production capacity within this year. Weilai launched a cooperative product with AR company Nreal to create an immersive cockpit entertainment experience space.

Zhang Xiang, an auto industry analyst in China, told the Global Times reporter that China is leading the global auto development trend, and there are few software in foreign cars, but there is a big market in China, and the software functions of new energy vehicles in China are generally more and richer than those in foreign countries. "In the past, the software of international car companies may be simple functions, but China’s car software can also integrate a variety of maps and entertainment software, which is also the contribution made by China car companies." Zhang Xiang analyzed this way.

Perspective of Industry Trend from Auto Show

The Global Times reporter observed at this auto show that under the blessing of "black technology" in software and hardware, new energy vehicles are showing stronger and stronger product strength and larger market space. Through this auto show, how do people from all walks of life view the future development trend of the new energy industry?

BYD said in its reply to the Global Times reporter that the first is that the market size of the industry will continue to expand. In the past three years, China New Energy Bus Station has achieved a spurt growth in the "double carbon" outlet, with an average penetration rate of 30% in the first quarter of this year, from 5% in 2020 to 15% in the previous year, and then to 26% last year, with a monthly penetration rate of 35% in March. The second is intelligent networking. In the future, new energy vehicles will be more intelligent and networked, and the combination of vehicles with emerging technologies such as the Internet of Things and artificial intelligence will bring more efficient, safer and smarter driving experience to human beings. The third is diversified development. In the future, the development of new energy vehicles will be more diversified, including new technologies such as pure electric power, hybrid power, hydrogen fuel power and extended range, which will promote the evolution of the automobile power market from different angles.

Li Bin, founder, chairman and CEO of Weilai, said: "I am full of confidence in the development of smart electric vehicle industry in China in 2023, and my confidence comes from the rapid recovery of China’s macro-economy and the improvement of user experience brought by the rapid progress of smart electric vehicle technology.".

Professor Heck Proff, director of the Department of Business Administration and International Automobile Management at the University of Duisburg-Essen in Germany, said in an interview with the Global Times on the 20th that the Shanghai Auto Show clearly showed that electrification and software are the two central themes of the current global automobile industry transformation. Without the remarkable skills in these two fields, no automobile manufacturer can exist independently for a long time, and China manufacturers have demonstrated that they have these skills in Shanghai.

  China news agency, Beijing, August 2nd (Reporter Huan Wang) Jacques, President of the International Olympic Committee? Rogge held his first press conference in the main press center of Beijing Olympic Games today. Apart from praising the Beijing Olympic Village, he also predicted that Asian sports would "wake up" in this Olympic Games.


  Rogge, who ended the one-day meeting of the IOC Executive Committee, came to the press conference and still looked radiant, waving to the media who had been waiting for a long time. The Executive Committee ended the discussion ahead of schedule today, which, in Rogge’s view, is a good start for this Olympic Games.


  Rogge, who attended the launching ceremony of the "Peace and Friendship Wall" in the Olympic Village on August 1st, was full of praise for this "first village on earth". "I am very fortunate to enter the Olympic Village and talk with Olympic athletes. They all think that this is the best Olympic Village in previous Olympic Games." Rogge recalled, "I myself have been in the Olympic Village since 1968, and the Beijing Olympic Village is very outstanding. This has also been recognized by national and regional Olympic committees and international individual sports federations. "


  When talking about sports achievements, Rogge predicted that Asian sports would "wake up" in this Olympic Games. He cited the figures of the Athens Olympic Games: "China won 32 gold medals, which was close to 36 in the United States, and Russian won 29 gold medals. This competition will be very interesting, because the host usually wins more gold medals and medals. China, South Korea, Japan and other Asian countries will present good medal figures, which is very exciting and expected. "


  Rogge specifically mentioned that some Iraqi athletes were allowed to participate in the Beijing Olympic Games at today’s Executive Committee meeting. "This also means that all 205 members of the International Olympic Committee will participate in this Olympic Games." The Beijing Olympic Games truly realized the great reunion of the Olympic family.


  "A week before the opening of the Athens Olympic Games, we were still worried about whether the competition venues could be built on time, and the Beijing Olympic venues began to hold test competitions one year in advance." Rogge once again emphasized the IOC’s affirmation of Beijing’s Olympic preparations. "I am very happy to see that the Beijing Olympic Organizing Committee has fulfilled its promise when bidding, and this Olympic Games will be very successful."

What is the significance of allowing foreign investors to set up entertainment venues in China according to law?

  Recently, the Ministry of Culture and Tourism issued the Notice on Adjusting the Examination and Approval of Entertainment Places and Internet Service Business Places.

  According to the Notice, according to the Decision of the State Council on Amending and Abolishing Some Administrative Regulations,Foreign investors are allowed to set up entertainment venues in China according to law, and restrictions on the proportion of foreign investment are abolished.Foreign investors applying to engage in business activities of entertainment places shall apply to the provincial administrative department of culture and tourism, and the application materials, establishment conditions and procedures are consistent with those of domestic capital.

  In addition, according to Article 58 of the Law of People’s Republic of China (PRC) on the Protection of Minors,Schools and kindergartens shall not set up entertainment places or business places for Internet service. The distance and measurement method between kindergartens and entertainment places and Internet service business places shall be specified by the provincial administrative department of culture and tourism in combination with the actual situation.

  Before the implementation of the Law on the Protection of Minors in People’s Republic of China (PRC), entertainment places and Internet service places have been set up around kindergartens. When the examination and approval authorities handle the renewal or change of business licenses, they should strictly follow the relevant laws and regulations, and earnestly implement the legal requirements that entertainment places and Internet service places should not be set up around kindergartens.

  Expert interpretation

  Yong Yang, a researcher at the Institute of Intellectual Property Law and Policy, East China University of Political Science and Law:The country has also further reformed and opened up to the outside world, giving enterprises more independent rights.At the same time, it is also considered that creating a better business environment and giving foreign investors a national investment treatment will still play a role in promoting and promoting the entire entertainment market. Through the opening up of foreign capital, the market activity will be further improved, which will enrich the spiritual and cultural life of ordinary people and bring a good impetus and prosperity.

  In the adjustment that entertainment places and Internet service business places are not allowed around schools and kindergartens, the Notice points out that the distance and measurement method between schools, kindergartens and business places shall be made by the provincial cultural and tourism administrative departments in light of the actual situation. Researcher Yong Yang also gave a related explanation.

  Researcher, Institute of Intellectual Property Law and Policy, East China University of Political Science and Law, ShanghaiYong Yang:Every city has a different volume, including Xuhui District in Shanghai, where there are 99 schools in more than 50 square kilometers. I think the interpretation of "periphery" should be given to the local cultural and tourism bureau according to the actual situation, which should not only ensure the prosperity of the market, but also maintain the legitimate rights and interests of the original enterprises, and at the same time effectively protect the rights and interests related to minors.

Kung Fu Panda 4 is a love letter to China’s Kung Fu movies.

"Kung Fu Panda 4" was released on March 22nd, and the panda A Bao returned to the big screen after 8 years’ violation.

The animated film Kung Fu Panda 4, co-directed by mike mitchell and Stephanie Ma stine, was released on March 22nd. This film is the fourth in a series of Kung Fu Panda movies, and the panda A Bao has returned to the big screen after eight years. In the English version, the comedian Jack Black once again returned to be the naive kung fu master Po. Bo Huang, Yang Mi and Rulu were the Chinese voices of Po, Xiaozhen and "The Phantom of the Demon" in Kung Fu Panda 4 respectively.

Kung Fu Panda 4 is a rare animated film that can capture the fourth episode. The Kung Fu Panda series, which has spanned nearly 16 years, has captured an amazing box office of about $2 billion in the world. The lovely panda Po is the protagonist of this legendary series. He shows the profound truth and universal concepts about self-discovery, overcoming fear and teamwork with stories full of oriental thoughts, which makes the series accumulate a very deep audience around the world. From the first movie, Kung Fu Panda series began to perfectly blend comedy, action and true feelings.

"I am a big fan of this series, and Kung Fu Panda is also one of the best series of movies ever. What excites me most is to explore its unique combination of comedy and action. Especially as a kung fu movie fan, there are extremely wonderful action fights in the story of this movie, and at the same time, comedy and animation are mixed together. It is a perfect opportunity for me. " Michelle, co-director of Kung Fu Panda 4, told the Beijing News that there will be more action scenes in Kung Fu Panda 4, because it is a love letter for China Kung Fu movies. "I like all kung fu movies, such as movies starring Bruce Lee, Kung Fu directed by Stephen Chow, Yuan Heping’s" Young Huang Feihong’s Iron Horse "and so on. We found inspiration in these movies, absorbed the essence and put them into this movie. For example, at the beginning of the film, Po raised his finger, which is a classic action of Bruce Lee. Of course, we must pay tribute to Bruce Lee. Another example is a landlady who is a powerful and skilled warrior. She has curly hair on her head, which seems to pay tribute to Stephen Chow’s movie Kung Fu (the chartered woman played by Yuan Qiu). "

Kung Fu Panda 4 has scenes to pay tribute to Bruce Lee’s classic movements and the rented woman in the film Kung Fu.

Simple Po wants to be a spiritual leader.

With Kung Fu Panda 4 leading the series into a new chapter, Po’s story has also taken a gripping turn, guiding him to embark on an inner journey about growth and change. With extraordinary courage and kung fu tricks of "punching the old master to death", the Dragon Warrior Po defeated some of the best kung fu villains in the world in the first three thrilling adventures. This time, fate summoned him to cultivate his body and mind. To put it bluntly, he was appointed as the spiritual leader of Heping Valley because of his simple nature, but this incident immediately triggered several obvious problems: First, Po knew nothing about how to be a spiritual leader, which was equivalent to letting him, who loved food, "eat birds and eat blood"; Secondly, Po should find a new Dragon Warrior as soon as possible, and train him to take up his post smoothly before he can retire and become a lofty leader, which is a process that needs thorough understanding and acceptance for him. To make matters worse, the powerful evil mage, the Phantom Queen (voiced by Viola Davis), has recently reappeared in the Jianghu. She is a petite lizard that can be transformed into the appearance of any animal, regardless of its size. After the Phantom of the Opera, those greedy little eyes are fixed on the staff of wisdom in Po’s hands. With it, she will be able to reconvene all the villains who have been hit by Po in the spirit world.

In "Kung Fu Panda 4", Po’s new partner is the cunning and witty thief Shahu Xiaozhen.

Therefore, Po is in urgent need of help, and then he meets the cunning and witty thief Xiaozhen (voiced by Awkwafina). This sand fox annoys Po all over, but her ability will help a lot. In order to protect the Valley of Peace from being trampled by the clutches of the Phantom of the Opera, tell it to the judge, who had frequent jokes, had to fight side by side. In this process, Po will find that unexpected places also meet heroes. Michelle said that in addition to being black and white, Po’s thoughts are black and white, and there are only good people and bad people in his mind. But this time, the newly added character Xiao is really a good and evil character. As a thief, she is still kind-hearted, which makes Po in a dilemma for a while. I don’t know if I can trust her. In the initial discussion, the production team found that Po rarely left the Valley of Peace, so they decided to take him out of the comfort zone and come to the new environment of Juniper City to get to know Xiaozhen. "We want to design such a movie, in which Xiaozhen and Po represent the city and the countryside respectively. Po from the countryside came to the big city for the first time, so we basically created a new york Times Square in an imaginary ancient China world, where all kinds of animals are in groups, and the number is more than you have ever seen before, including rhinoceros, sheep, wild boar, domestic pigs, goats, crocodiles and bears." In Kung Fu Panda 4, the scenes visited by Po and Xiaozhen are broader than those in the previous work. Michelle said, "This magnificent world has caused Po to change, making him realize that he may be ignorant. As he explores this vast new world, he also comes into contact with all kinds of people.Accepted the concept that the world is not only black and white. This journey made Po wise and saw that there were more than just good and evil sides in the world. "

A team of more than 500 people creates a multicultural perspective

The production team took the time to polish the story and characters of this film carefully, and also paid attention to the standards set by previous films. "This movie has been separated from the last one for eight years, and we have to live up to our high expectations. The first three movies have been a great success, and the fans of Kung Fu Panda have been growing from the first one, constantly crossing the age group. Our goal is to create a movie that can resonate with men, women and children. It not only pays tribute to the memories and legends of the previous work, but also introduces new, interesting and exciting elements. We want to strive to achieve a balance between the two. " Michelle introduced that in the process of cooperation in finalizing the story, the team of Kung Fu Panda 4 created a vibrant and creative environment: "About 500 people contributed to this film, bringing diversified perspectives to the story, sharing the same opinions and goals with everyone, making the finalization process exciting, and allowing us to introduce new ideas on the basis of retaining the styles and feelings of the first three films."

There are about 500 people behind Kung Fu Panda 4, who come from all over the world.

Stephanie Ma stine, the co-director of this film, is a Chinese-American female directors. In the final stage of the production of Kung Fu Panda 4, the complex culture in which she grew up also brought a lot of fun and knowledge to the whole team. "My family comes from China, so I will teach the crew to play mahjong, a game that my father once joked would lead me astray," she said. "But now I’m here, taking my colleagues to enjoy the fun of this China game. From the peaceful valley with rural customs to the bustling city of juniper, we have been trying to capture this extensive culture in the movies. Our attention to small details, such as whether a food is authentic or not, has created a sense of richness for the world of Kung Fu Panda, which is constantly resonating with audiences around the world. " Michelle and the production team pay great attention to realism, and the final product is a love letter they wrote to China culture, martial arts and the whole series of Kung Fu Panda. He said, "Since the release of Kung Fu Panda 3, the world has improved a lot, and we have also noticed these changes, and tried to add more diversity to our actors, crews and later stages, and even Kung Fu has evolved. Many of our animators and artists still clearly remember how they watched Kung Fu Panda when they were young, and they were all very excited that they could contribute to the series of movies they liked since childhood in this new work. "

Behind the scenes

1. In order to capture the real kungfu movements, Sean sexton, director of animation roles with background in Taekwondo and Aikido, integrated the realistic mechanism into Po’s movements. sexton’s team cooperated with a stunt director and several performers to shoot many accurate reference shots for animation.

2. For the inspiration of camera following, animated characters and action scenes, the production team invited stunt coordinator and martial artist Don Ty Theerathada as the kung fu consultant for this film. Theerathada and his stunt team used to be responsible for the fight scene design and arrangement of many action movies. In addition, the stunt team also photographed the scene reference for the animators, who used props designed to imitate the characters’ costumes, costumes, horns, tails and other characteristics to study the natural movements of animals.

3. In the process of making Kung Fu Panda series, animation technology has also made great progress. These technological advances have achieved dynamic camera following, enhanced lighting and unlimited facial feature control for Kung Fu Panda 4. However, despite the technological progress, the animators still combine the old-school and new-school technologies to create traditional hand-drawn pencil drafts for action scenes.

The big villain in Kung Fu Panda 4, the Phantom of the Demon Queen.

4. The film adopts the opinions of Dr Stuart Sumaida, a biologist and vertebrate paleontologist, to help shape the Phantom of the Phantom and the Queen and her army of Komodo dragons. The physiology, movement and independent rotation of eyes of these characters have been carefully designed.

5. It is a complicated process to shape the transformation after the Phantom of the Opera, which is inspired by movies such as The Ring of the Rings at Midnight, X-Men, Nightcrawler and Little Yellow Man with Big Eyes. In order to pursue the details of the transformation, this character is bound with more than 8,000 control points. In order to solve the clothing problem during the transformation of the Phantom of the Opera, the design is adjusted to seamlessly inhale the clothing into the skin.

Welcome the audience to watch Kung Fu Panda 4 at Dolby Cinema in Belle Palace and enjoy the ultimate audio-visual experience.

The North Sea Fleet leads mass training activities with competition.


China’s navy is holding a military parade at sea. (information photo)


  On February 25th, the largest professional and technical competition in the history of the North Sea Fleet came to an end after three days of fierce competition. The officers and men of the fleet stationed on the long coastline of the northern part of the motherland shared the grand occasion of the awards and commendation meeting through various video calls. The "top trainers" and "technical experts" who won 210 individual medals and 52 team medals in 16 majors and 85 events went to their respective positions with great pride.


  The Jingwu arena is fiercely competitive, and the drums are inspiring. There are many "highlights" and frequent "highlights" on the competition field.


  "Ending" becomes "Opening"


  In previous years, military competitions were generally arranged in the second half of the year. As the "ending" project of annual training, it is more to play the functions of "acceptance" and "evaluation".


  However, as soon as the training of the North Sea Fleet started this year, it began to compete with unprecedented professional skills. What is the intention of "ending" to "opening"? During the interview, the reporter learned that the preparation for this competition has actually been fully rolled out in the fleet forces since March last year.


  It is the original intention of the fleet leaders to set this grand contest at the beginning of the year to lead the fine martial arts and create an atmosphere of on-the-job training. Liu Shusen, deputy captain of a landing ship who won the title of captain’s professional competition, told the reporter that from the professional and technical competitions held at different levels of ships, brigades and detachments, he was "killed" by the fleet all the way.


  "Soldiers are the most glorious warrior. The contest shows strength and heroic spirit, and no one in each unit will admit defeat. " A destroyer detachment organized troops to hold full-staff, full-post, full-specialty and full-system professional and technical competitions, and conducted intensive training for the contestants by means of centralized teaching, classified guidance and on-site observation, and eliminated them in turn and selected them at different levels.


  With the competition as the traction, this fleet has set off a vigorous training upsurge from the grass-roots ship company to the divisions and regiments, from ordinary soldiers to leading cadres, from front-line personnel to security forces. Tong Haiqing, political commissar of a speedboat detachment, said: The competition has promoted the enthusiasm of officers and men for training. The officers and men on the small landing craft know that it is difficult to jump into the ring of the fleet, and they are also gearing up for their posts; Some "unique" majors are too few to compete, and they also strongly demand to set up competition projects for them.


  It’s better than not knowing, and it’s better than knowing. Chen Guiqiu, deputy director of the Military Training Department of the Fleet, vividly compared: This is a "general survey" of the combat effectiveness of the troops. Although it is impossible for all officers and men to become top trainers, they can find out which fields and majors have talents by conducting competitions at different levels. Which ship, which battle position lacks backbone, and which projects are still weak. This is undoubtedly conducive to enhancing the pertinence of training guidance, reinforcing the strong and reinforcing the weak, and promoting the whole.


  This competition adapts to the development of equipment and technical progress, tests the latest level of professional technology, sets a new benchmark for military training, and lifts the professional technical training of the fleet to a higher starting point.


  "Watching the war" becomes "participating in the war"


  "Veterans fight and recruits watch." This seems to have become a fixed trend in the previous military competitions, and the "technical skills" that dominate the ring are mostly "old faces". However, this time, senior non-commissioned officers only accounted for a small number of contestants, and more new forces such as conscripts and junior non-commissioned officers bravely appeared.


  Chen Lixing, a new generation pilot of Hainan Airlines who just graduated last year, competed on the same stage with Zuo Wenmeng, a pilot of the deputy division for 30 years. Each of them performed their unique skills and competed fiercely for two hours, making it difficult to win or lose.


  On the one hand, the old horse is full of courage, and on the other hand, the newborn calf dares to fight. The reporter saw in the competition field that in the professional competition of guns, Du Haitao, a superior soldier who had just joined the army for one year, fought fiercely with He Maobin, a four-level sergeant with rich experience; Wang Mian, a first-class petty officer, competed with Zhang Guochao, a third-class petty officer, and Zhang Chunying, a major female officer, which became the most eye-catching attraction on the field.


  In recent years, the composition of soldiers has changed significantly, and many college students have joined the army. Some recruits have undergraduate and junior college degrees, and they are highly savvy, receptive and quick to master new technologies. Coupled with the changes in the military training environment in recent years, weapons are frequently used in practical activities such as long-distance training and major exercises, and the training intensity is high. Officers and men are also greatly trained in their posts, and the growth cycle of professional and technical experts is obviously shortened.


  It’s no better than not knowing, and it’s a "shock"! This new force in military training has activated the training ground. Song Wei, a 315 submarine rudder technician and a fifth-class noncommissioned officer who won the first prize of outstanding noncommissioned officers in the whole army, said frankly when participating in the professional competition of submarine signals: "The strength of new players can not be underestimated, forcing us old backbones not to slack off!"


  In the past, post training focused on training "soldiers", and this time the professional competition cadres no longer watched the excitement. The reporter opened the competition order book and saw that the contestants included ship captains, pilots, staff officers and technical cadres. The most interesting thing is the number of ship captains and flight group leaders. They have heavy burdens and busy work, but they also attach importance to laying a solid foundation like soldiers and players, and put pressure on themselves through competitions.


  Liu Shusen, the deputy captain of a landing ship, took the time to learn the knowledge of command and safety theory, exercised command skills in practical tasks, and achieved the combination of learning and application. In this competition, he won the first place in the professional competition of the captain of the ship, showing a solid commander’s foundation.


  "Supporting role" becomes "protagonist"


  At the scene of the equipment professional competition, the reporter saw that the "grinding technology" that had been "forgotten" for many years reappeared in the competition ring. Twenty-two contestants "copied" the same model of spare parts on the mechanical operating platform, and raced against time to process the grinding parts. Zhang Dingxi, a five-level sergeant of a destroyer detachment, told the reporter: "I have participated in professional competitions organized by higher authorities many times, and this project has not been compared for many years."


  The highlight of this North Sea Fleet competition is "professional technology", which covers all fields and covers all majors. From the combat use of missiles, torpedoes and artillery to the practical operation of electromechanical, communication and chemical defense; From the supply guarantee of diet, medical care and oil, to the troubleshooting and emergency repair of equipment, equipment and facilities, not only the "main" major has made a strong appearance, but also the "marginal" category has made a new appearance.


  The purpose of such a comprehensive and extensive competition project is to fully cover the usual basic training. Professional technology is the basis of combat effectiveness, and no link in the combat effectiveness chain can be missing. Some "marginalized" professional technologies also have the opportunity to exert their fists. Yu Yongfeng, a second-class noncommissioned officer in the equipment warehouse of a security base, and five comrades-in-arms are setting up a new class tent at the professional competition site of the infrastructure barracks. They cooperated with each other quickly and achieved the second place in the group.


  According to statistics, there are 26 new events in this competition, whether they are "resurrected" or "newborn", and the project settings will follow the needs of future wars. According to the requirements of the new syllabus, the content of dealing with various security threats and improving the ability to complete diversified military tasks has been added to the competition. The reporter saw at the scene of the competition between the captain of the ship and the pilots that the knowledge points such as "maintaining the safety of important strategic passages at sea" and "maritime international law" all entered the test paper of the theoretical competition.


  Tournament not only highlights the important position of basic training, but also makes officers and men fighting in different positions firmly believe that professional skills are only "high and low" and have no status "high and low". They broke the traditional concept of "leading role" and "supporting role" and re-defined their roles: all professional and technical posts related to combat effectiveness should be pursued by you, actively trained, laid a solid foundation and used well, so as to promote the overall combat capability of the fleet to jump!

The domestic large aircraft C919 made its first flight today, and the overall localization rate reached over 50%.

  Guangming. com May 5 th (Reporter Zhan Wei)This afternoon, the domestic large passenger plane C919 will make its first flight at Shanghai Pudong International Airport. From 1970, when the project was initiated to develop "Yun 10", to 2007, it was decided to carry out the reform of aviation industry system, and the project was initiated to develop C919. The civil aviation industry in China experienced a difficult and bumpy development course. The moment of the first flight of C919 bears the struggles and dreams of several generations of China civil aircraft people. Let us have a more comprehensive understanding of C919.

The domestic large aircraft C919 made its first flight today, and the overall localization rate reached over 50%.

  On May 4th, in the hangar of Zhuqiao Base of China Commercial Aircraft Corporation Flight Test Center, the staff inspected and maintained the domestic large passenger plane C919. Xinhua news agency  

  Why is it named C919?

  According to Comac China, the full name of "C919" is "COMAC919".

  Among them, "COMAC" is the abbreviation of the English name of Commercial Aircraft Corporation of CHINA Ltd, which developed C919. The "C" in the abbreviation is the first letter of "COMAC" and the first letter of China’s English name "China".

  The first 9 means "everlasting", and the last two 19 means that the maximum capacity of C919 passenger plane is 190 passengers.

  Previously, the internationally renowned aircraft manufacturers were Air Bus and Boeing, and from A to B to C, they just lined up.

  What kind of research and development process has C919 experienced?

  According to official website of China Commercial Aircraft Corporation, C919 is a large jet civil aircraft developed by China in accordance with international civil aviation regulations and with independent intellectual property rights, with 158-174 seats and a range of 4,075-5,555 kilometers.

  It took 10 years from 2007, when the major scientific and technological special project of large aircraft development was formally approved, to 2015, when the first aircraft of C919 was assembled and rolled off the assembly line in China Commercial Aircraft Assembly and Manufacturing Center, and today, the domestic large aircraft will soon fly from blueprint to flying in the blue sky for the first time.

  During this period, researchers have planned 102 key technical problems for advanced pneumatic layout, structural materials and airborne systems. In preparation for the first flight, the C919 has completed 118 test projects and experienced 21 taxiing tests including low, medium and high taxiing, and passed the expert technical review in March 2017 and the release review in April.

  Why is the first flight important?

  The first flight of an airplane refers to the first flight of a newly manufactured airplane from the ground. Every plane has its first flight, but the first flight of a new model has its special significance. It is not only an important link in a series of work chains, such as changing ideas into drawings, drawings into objects, and objects can fly, but also an important milestone in the turning point of new models from static to moving and the birth of new models.

  According to the relevant person in charge of Comac, as long as the plane begins to taxi and leave the ground during the first flight, the most basic system functions will be preliminarily assessed. The test pilot will comment on the aircraft’s handling stability, take-off and landing performance, power plant and driving equipment for the first time. Generally, the first flight time of light aircraft does not exceed 30 to 40 minutes, and that of large aircraft is 1 to 2 hours. Generally, the first flight chooses a good weather, with visibility not less than 5 to 7km, and no low clouds and crosswinds. The flight weight of the first flight plane should be reduced as much as possible, so as to minimize the take-off speed from the ground and shorten the take-off taxi distance, thus improving driving conditions.

  How to fly on the first flight?

  The maximum altitude of the first flight of C919 is 10,000 feet, the maximum speed is 170 knots, and there are 15 test points. The whole process is divided into five stages, namely, ground inspection stage, climbing stage, level flight stage, simulated approach, landing and go-around stage and landing stage. Traditionally, the C919 did not retract the landing gear during the first flight, and kept the flaps down.

  In addition, when the C919 makes its first flight, a second plane will accompany it. The task of companion flight is to observe the first flight plane in real time in the air, record flight data, take photos and videos, and make every effort to ensure the safety of the plane during its first flight. In case of any problems, the crew of the accompanying plane will immediately warn the crew of the first flight, report to the ground control personnel and guide the first flight to land safely. In addition, the accompanying aircraft will also monitor the air environment of the first flight to ensure that no other aircraft will break into the flight route of the first flight and put an end to any hidden dangers of stealing secrets.

  How about the localization of C919?

  Zhou Guirong, deputy chief designer of C919 large passenger aircraft, said that at present, the overall localization rate of C919 aircraft can reach more than 50%, including domestic enterprises and joint ventures at home and abroad. The safety requirements of aviation products are very high. The development of the whole localization, whether at home or abroad, is in accordance with the same set of international standards and methods, and the trial is also in strict accordance with international standards and norms.

  China Commercial Aircraft Corporation insists on "main manufacturer — Supplier "development mode, maximize the gathering and utilization of domestic and foreign resources, and build a" life community "of the civil aircraft industry. There are 22 provinces and cities, more than 200 enterprises and 36 colleges and universities involved in the development of C919 large passenger aircraft. Sixteen material manufacturers and 54 standard parts manufacturers including Baosteel have become suppliers or potential suppliers of large passenger aircraft projects. China Comac also signed strategic cooperation agreements with six central enterprises, including aviation industry corporation of china, and established strategic cooperation relations with seven major domestic banks.

  In the development of C919 large passenger plane, researchers have planned 102 key technical problems, including integrated design of aircraft engine, control law design of fly-by-wire flight control system, active control technology, etc., aiming at advanced aerodynamic layout, structural materials and airborne system.

  Take most of the front fuselage of C919 as an example, which includes the front passenger cabin, the front cargo cabin and the recirculation fan cabin, and contains more than 1,600 parts, involving nearly 2,000 tooling. This section adopts the third generation aluminum alloy — — Al-Li alloy material, which is the first time in domestic civil aircraft application. Al-Li alloy material is considered as the most ideal material for aerospace at present. China Commercial Aircraft Corporation and AVIC Hongdu Aviation, a joint supplier, have completed 20 batches of material performance data tests under stable process conditions through the tests of 2,500 test pieces in recent three years. Around the establishment of material fatigue rating (DFR) data system, DFR fatigue tests of typical structural details in different processing and manufacturing States were carried out, with more than 3,000 test pieces. The processing technology of Al-Li alloy structure, such as chemical milling, machining, hole-making, hot-pressing subsidence, mirror milling and heat table treatment, has been fully verified. Through tackling key problems, the model material specification system and performance data system for design are gradually established.

  How did the C919 market react?

  Focusing on the most mainstream air transport market, C919 is a trunk aircraft developed in full compliance with international mainstream airworthiness standards and international mainstream market operation standards. At present, C919 large passenger aircraft has 23 domestic and foreign customers, including China International Airlines, with a total order of 570 aircraft, including international customers such as GECAS.

  What is the significance of C919 to China?

  Large aircraft is a high integration of modern high technology and is called "the jewel in the industrial crown". C919 means that China’s civil aviation will no longer rely on foreign imports, and China’s aircraft manufacturing has truly embarked on a road of independent development.

  Driven by the C919 large passenger aircraft project, a technological innovation system of civil aircraft has been formed, which is based on China Commercial Aircraft Corporation, market-oriented and combined with Industry-University-Research. China Commercial Aircraft Corporation (Comac) has built a technical responsibility system around the realization process of civil aircraft products and the technical requirements of full-life cycle service, and planned to promote the technical system construction with standards and specifications as the main carrier. Through scientific research and innovation research, model technology research and other ways, it has continuously formed new civil aircraft technical achievements and supplemented and improved the civil aircraft technical system.

  Millions of fine parts, covering high-end manufacturing of almost all industrial categories — — Domestic large aircraft soaring in the blue sky will undoubtedly drive China’s manufacturing industry to the "smile curve".

  From the upstream, the development of large passenger aircraft can drive the group breakthrough of key technologies in new materials, modern manufacturing, advanced power, electronic information, automatic control, computers and other fields, and can promote the development of many high-tech industries, with a technology diffusion rate as high as 60%. The technological upgrading of its industry will inevitably require great progress in many basic disciplines, including fluid mechanics, solid mechanics, computational mathematics, thermophysics, chemistry, information science, environmental science and so on. From the downstream, the commercial operation of large civil aircraft has a great impact on civil aviation transportation, aviation maintenance, aviation finance, tourism, logistics and other industries.

  For China, the breakthrough of large-scale aircraft technology will not only promote the development of a number of new industries, but also force the upgrading of China’s industrial standards by continuously expanding the industrial chain and introducing airworthiness certification in China, thus promoting the overall improvement of China’s industrial manufacturing capacity and level. Some experts said that in the 21st century, only a breakthrough in high-end large-scale equipment manufacturing such as large aircraft can support the foundation of China as an industrial power. At the same time, it also contributes to the transformation of China from a "manufacturing power" to a "manufacturing power".

Homework can’t be solved by search software? This phenomenon should be managed.

  With the search software, my mother no longer has to worry about my study?

  But in reality, there is such a problem. Students who make perfect exercise papers don’t score high in the exam. Usually, when you encounter homework problems, open the network search software to check, and the direct answer will come out, and the exercise paper will be completed well and quickly; But in the examination room, there is no "blessing" of the search software, and the same problem-solving ideas are full of mistakes.

  On the eve of the Eighth Young Pioneers Congress in Shanghai, many young pioneers, including Maree Lau from Shanghai No.54 Middle School and Tang Ying from Tangwai Middle School in Fengxian District, paid attention to this phenomenon and made investigations. At the same time, they submitted relevant proposals, suggesting that the number of times of searching questions by using search software should be limited, and the software should provide ideas for solving problems instead of giving answers.

  The exercise paper is perfect, but I guess it even in the exam.

  Maree Lau, a student from Shanghai No.54 Middle School, was very impressed by an exercise paper on the calculation of mathematical real numbers, and the steps of each calculation problem were impeccable. But in the math exam, the student who made the perfect exercise paper didn’t score high.

  Exploring the reasons behind it, Maree Lau found that many students around him did not think about how to solve the problem by themselves first, but habitually turned on the network search software to check the answer, and easily made a perfect score assignment through the function of tapping the question in seconds by some software. "Solving problems without thinking is useless for learning. They often expose many problems in exams." Maree Lau said.

  Tang Ying, a student from Tangwai Middle School in Fengxian District, also found that some students around her used the online search App and conducted "autonomous learning". The completion of homework achieved acceleration, but the learning attitude and independent thinking ability were greatly affected. I could only guess in the exam, and the error rate soared.

  How many students have tried to solve problems with search software? Maree Lau and Tang Ying conducted research in their schools respectively.

  The former found that the survey showed that 85% of the students would use the search software when they encountered problems, and more than 70% of the students chose "Yes" when answering "Do you have any excellent homework by software around you?".

  The latter found that more than 90% of the team members are familiar with homework search software or channels such as homework help and Little Ape Search, among which more than 50% of the team members have used this method for "autonomous learning" or homework completion, including those with excellent academic performance.

  Tang Ying said frankly: "Some of these players use the software to find ideas for solving problems and read excellent articles, while others copy the answers directly and just want to finish their homework as soon as possible."

  Maree Lau also noticed the feedback that "the software sometimes gives wrong answers". To this end, she used the software to carry out experiments and found that some questions will have correct answers and two or three wrong answers at the same time. "It is a difficult problem that can’t be solved, and then giving the wrong answer will not only solve the problem, but also mislead the questioner."

  Limit the number of times of use and only give ideas for solving problems.

  At Tangwai Middle School in Fengxian District, Gu Bei, a team counselor, also organized an in-depth discussion. As a result, I heard the voices from the players.

  "They said that they sometimes want to ask their parents about the questions they can’t do, but the other party is always busy looking at the mobile phone and letting the children go online to check the answers. Sometimes the other party will also look at the problems encountered by the children, but it turns out that they won’t do it either, and finally they will check it online." Gu Wei said.

  As a teacher, Gu Bei does not advocate the use of online search software, but she also noticed that "there is a demand behind this problem". The key is to let students understand what the "initial intention" of using software is, "is it to help them learn the problem-solving ideas or just to be lazy and have fun?"

  Maree Lau also said that when the search software becomes a "helper" to complete homework, students will be overly dependent and lose their independent thinking ability.

  Maree Lau suggested that the search software can be used as a platform to assist students in learning, but it is necessary to "limit" the number of questions per day. "I think it is better to limit the number of questions per day to less than 10 times, and then refer to it if it is not."

  In addition, she thinks it’s best to use the software in real-name registration system. A student can only apply for one number, and the software should also check the correctness of the answers to the questions regularly.

  Jiang Chenyue, a small representative from Shangmei Middle School in Qingpu District, Shanghai, suggested that the right to use the software can be "restricted". "For example, we don’t give the answers directly to the questions we check, but give the ideas for solving the problems, so that we can use our brains to solve them ourselves."

  Tang Ying suggested that if the team members want to reduce the use of search software, the subject teachers in the school can analyze and record the problems and upload them to the campus APP, so as to provide problem-solving ideas for the team members’ learning. By learning videos and punching in points, the team members can be encouraged to see more, think more and compare more.

  Tang Ying also suggested that a "study group" can be set up in the squadron, and a study group system can be set up to study together during recess and after school. "Parents should never save trouble, just throw us to mobile phones and computers, and you can watch online problem-solving ideas with us and solve problems together."

Water turns into ice, reflecting sunlight.

Recently, affected by the continuous cold air, many places in China have ushered in a wide range of snowfall. On the morning of February 25th, in the Evergreen Flower Community of Dongxihu Lake, the original accumulated water gradually froze in the cold, with different shapes, reflecting the rising sun.
With the continuous drop of temperature, the accumulated water in the community gradually freezes. Especially in some low-lying areas, the accumulated water forms a thin ice layer, which forms a beautiful picture with the surrounding buildings and trees under the sunlight.
While the continuous snowfall has brought beautiful scenery to the residents of the community, everyone should also pay attention to the weather changes and their own safety.(Changjiang Daily reporter Liu Bin photo report)
