Holiday ticket seconds？ 12306 responds to the difficulty of grabbing tickets： this year is more difficult than previous years.

According to China National Railway Group Co., Ltd. (hereinafter referred to as China State Railway Group Co.,Ltd.), this year’s Mid-Autumn National Day Golden Week railway transportation will last for 12 days from September 27th to October 8th, and the national railways are expected to send 190 million passengers.

On September 13th, Railway 12306 began to sell train tickets for Mid-Autumn National Day Golden Week.

How can it be so difficult to grab tickets!

On September 14th, as the Mid-Autumn Festival approached, many netizens joined the army of grabbing tickets in advance and began to snap up the train tickets on September 28th.

During the snap-up, some netizens’ tucao system showed that the remaining tickets were sufficient, but they still had to queue up to buy, "711 people lined up in front"; Some netizens questioned whether third-party software grabbed tickets and occupied the "pit position" of ordinary users.

In this regard, 12306 customer service said that there are still enough tickets to queue up because there are too many users who place orders at the same time. 12306 has a fixed time to open ticket sales, and will not sell tickets in advance for third-party software.

For users who have not bought tickets, the customer service said that it is indeed more difficult to grab tickets this year than in previous years. It is recommended to join the standby immediately and wait for other users to change their tickets or refund their tickets.

In addition, in the case of a large number of passengers, the high-speed train may also be changed from 8 cars to 12 cars, and the alternate ticket purchase can buy tickets faster.

The success rate of 12306 standby ticket purchase is 75%

Regarding the Mid-Autumn Festival and the National Day holiday, China State Railway Group Co.,Ltd. responded to the question of whether some popular train tickets will run out of seconds.

1. Is the transportation capacity guaranteed during the peak holiday passenger flow?

A: In view of the peak passenger flow during the Mid-Autumn Festival and National Day holiday this year, the railway department will scientifically allocate transportation resources and increase transportation capacity. The national railways will implement a peak operation chart, and the daily average passenger seating capacity is expected to increase by 18.5% compared with the same period in 2019. Mainly take the following measures: First, extend the golden week transportation period, reaching 12 days before and after, and the transportation period exceeds the golden week over the years. The second is to open 320 through passenger trains across the Railway Bureau Group, including 214 EMU trains (including 200 night high-speed trains) and 106 ordinary passenger trains. The third is to increase the number of passenger seats in popular directions by means of reconnection of EMUs and adding carriages to ordinary passenger trains. In principle, the directions of entering Beijing, Shanghai and Guangzhou are full-scale or full-grouped. Fourth, according to the ticket sales data of Railway 12306, each railway bureau group company flexibly increased the number of passenger trains in the pipeline.

2. If there is a sudden large passenger flow, how does the railway department respond?

A: The railway department has reserved hot-standby EMUs, ordinary passenger trains and vehicles and crew members at major hub nodes in the country, the number of which is not less than the May Day holiday. Once there is a sudden passenger flow, it can be put into operation at any time to meet the travel needs of passengers.

3. What are the tips for purchasing tickets?

A: The railway department predicts that the peak of ticket sales during the Mid-Autumn National Day Golden Week this year will appear on September 15th, when tickets for the first day of the September 29th holiday will be sold. It is expected that Beijing, Shanghai, Nanjing, Suzhou, Tianjin, Guangzhou, Shenzhen, Chengdu, Xi ‘an and other cities will become popular areas for tourists to start and arrive. In addition, Hangzhou will host the Asian Games during the Golden Week, and it will also become a popular destination for high-speed rail travel.

4. During the Mid-Autumn Festival and National Day holidays, will there be a "second light" phenomenon in some popular train tickets? Why did this happen?

A: During the Golden Week, passengers’ travel demand "bunched up", resulting in tight transportation capacity in some areas and time periods. Especially on some popular routes, some trains with more suitable departure and arrival time and shorter travel time are the first choice for many passengers. When these train tickets are on sale, because they are highly concerned by the majority of passengers, passengers and friends will choose 12306 online ticket purchasing, mobile App, station window and other ticketing channels to "grab tickets" quickly, and there may be "second light" phenomenon.

5. Why does the 12306 ticketing system of the same train show that there are full tickets and long-distance tickets, but there are no half tickets and short-distance tickets?

A: The railway department will give priority to the long-distance passengers who take the bus from the departure station to the terminal, so as to maximize the utilization of transport resources. Of course, it will also take into account the needs of short-distance passengers. When the long-distance ticket amount is sufficient, it will dynamically adjust the ticket amount according to the changes in passenger demand, and automatically transfer some tickets to stations along the way in different time periods to meet the travel needs of short-distance passengers.

6. How is the standby ticket purchasing function of Railway 12306 running? How can we increase the chances of successful standby ticket purchase?

A: Railway 12306′ s alternate ticket purchasing function runs stably, and the alternate redemption success rate reaches over 75%. Passengers can increase the standby success rate by submitting a number of standby orders with a combination of "date, train number and seat" to extend the standby redemption time.

7. How is the ticket release time of Railway 12306 arranged?

A: The pre-sale period of train tickets is 15 days (including that day), but the starting time of each station is different. For example, Beijing West Railway Station and Nanjing South Railway Station are at 8:00, Guangzhou South Railway Station is at 10:00, and shanghai hongqiao railway station is at 13:30. Passengers can use the "starting time" query function in the official App of "Railway 12306" to query the starting time of the designated station.

8. How is the online paving function of the Railway 12306 pilot running? How to ensure that the elderly give priority to the lower berth?

A: In June this year, 12306 began to try out the online shop selection service. At present, it has covered 230 passenger trains and is running well. Online berth selection service provides the choice of soft berth, hard berth for general-speed trains and soft berth, first-class berth and second-class berth for emus, which cover different levels of demand. At the same time, Railway 12306 still insists on giving priority to the allocation of the lower berth to key passengers such as the elderly over 60.

9. What should passengers do if they can’t buy a direct ticket at the peak of passenger flow?

A: If you can’t buy a direct ticket during the peak passenger flow period, passengers and friends can buy a joint ticket to meet their travel needs by taking a bus in sections. Railway 12306 will intelligently recommend a transfer plan with a spare ticket for passengers to choose from according to their travel needs and the situation of the remaining tickets. In order to facilitate passengers’ transfer, the railway department has set up convenient transfer passages in 100 major stations, and arranged station staff to provide guidance services, so that passengers can enter the waiting room without leaving the station, effectively shortening the transfer time.

10. Is there any risk in buying tickets through third-party websites?

A: Railway 12306 has never authorized any third-party platform to sell train tickets. Third-party platforms will retain user information in the process of passenger ticket purchase, which not only has "traps" such as surcharges and bundled sales services, but also may have the risk of personal information disclosure. Passengers are requested to purchase tickets through official railway channels, and look for www.12306.cn, the official website of 12306, and the official App of "Railway 12306".

11. How does the railway department deal with some uncivilized behaviors in the car?

A: The railway is a popular means of transportation, which requires the vast number of passengers and friends to jointly maintain a civilized, orderly, warm and comfortable travel environment. However, there are also uncivilized behaviors of some passengers, such as smoking, dominating seats and making loud noises during the operation of EMU trains, which seriously affects the riding experience of other passengers, and some even endanger the safe operation of trains and violate laws and regulations. During the Mid-Autumn Festival and National Day Golden Week holidays, we will broadcast videos by train, increase publicity and guidance, actively advocate civilized travel, and strive to create a good travel environment. Some uncivilized behaviors will be discouraged in time. Especially serious, we will be included in the untrustworthy list of the railway credit information system according to relevant regulations.

Shenyang launches five projects of vision health to prevent and control adolescent myopia scientifically.

　　Zhongxin. com, Shenyang, November 6 (Li Wei) In order to scientifically prevent and control the myopia of children and adolescents, so that every child has a pair of bright eyes and a bright future, Shenyang has launched five projects, including the vision health education promotion project, the health education project, the healthy school construction project, the teaching-health collaboration project and the family eye protection promotion project, to comprehensively strengthen the comprehensive prevention and control of myopia of children and adolescents. On November 6, Zhao Renjun, deputy director of Shenyang Education Bureau, said at the press conference held by Shenyang Municipal Government Information Office.

　　With the popularity of mobile phones, Ipad and other electronic products, the myopia rate of children and adolescents continues to rise, which has become a public health problem of universal concern. It is urgent to prevent and control myopia among adolescents scientifically. The latest survey data released by the National Health and Wellness Commission of China shows that the overall myopia rate of children and adolescents in China is 53.6%. Among them, 14.5% are 6-year-old children, 36.0% are primary school students, 71.6% are junior high school students and 81.0% are senior high school students.

　　Zhang Chunqing, director of Shenyang Health Service and Administrative Law Enforcement Center, said that in order to give full play to the advantages of health system resources and effectively improve the eye health level of children and adolescents. In the past two years, 34 schools and kindergartens have been monitored, and 10191 children and students of all age groups have been investigated. Through statistical analysis and evaluation, the myopia status and influencing factors of students in Shenyang have been fully understood and mastered, which provides a scientific basis for formulating prevention and control measures for myopia in Shenyang.

　　At the same time, students’ free vision screening, health intervention and diagnosis and treatment services will be carried out. Provide children’s eye care and vision examination services for children aged 0-6 in the city; Taking the "Bright Future" campus vision screening public welfare action in Shenyang as the carrier, the relevant hospitals were organized to actively cooperate with the education department to carry out free vision screening for more than 650,000 students in 573 primary and secondary schools in the city, and to provide personalized and targeted health intervention and diagnosis and treatment services for students with abnormal vision found in the screening.

　　Carry out supervision and inspection of school health law enforcement. A special rectification campaign was launched for the health supervision and inspection of myopia prevention and control of students with "students’ health and blue shield escort". Together with the Municipal Education Bureau, the school health supervision and law enforcement inspection was carried out on the indicators of "classroom lighting and lighting" in 160 primary and secondary schools in a "double random" way, and the third party was introduced to carry out testing, which urged the rectification of the problems found and effectively promoted the improvement and upgrading of school environmental sanitation.

　　Thomas lee, deputy director of the Shenyang Sports Bureau, said that in order to make every teenager have a bright ear and a healthy growth. Shenyang comprehensively strengthens children’s and teenagers’ activities and competitions, so that students can move, practice and compete. At present, there are 58 traditional sports schools and 20 experimental schools in the city. Every year, 53 youth sports events of all levels and types are organized, with more than 11,500 participants. In the next step, we will actively organize various winter and summer camps, training camps and other activities, extensively carry out sunshine sports activities for young people, and actively guide and support social forces to carry out various sports activities for children and young people.

　　Zhao Renjun said that Shenyang will vigorously promote the construction of health promotion schools in the next step. By 2020, the proportion of health promotion schools will reach more than 50%, and it will increase year by year. At the same time, ensure the implementation of environment and equipment standards closely related to visual health and myopia prevention and control. Before the end of 2020, 100% of the standards should be met, and actively provide students with a learning environment that meets the requirements of eye hygiene.

Promote the integration and development of intangible cultural heritage and tourism

"Learn to think and practice"

China is rich in intangible cultural heritage resources. By the end of 2023, more than 100,000 national, provincial, municipal and county-level intangible cultural heritage projects have been identified, and 43 projects have been included in UNESCO’s representative list and roster of intangible cultural heritage of mankind, ranking first in the world. In recent years, the upsurge of traditional culture in various places has surged, and the demand for cultural tourism consumption has been continuously released. Finding the "greatest common denominator" between the systematic protection of intangible cultural heritage and the high-quality development of tourism and promoting the deep integration and development of intangible cultural heritage and tourism are of great practical significance for solidly protecting intangible cultural heritage, promoting the high-quality development of tourism and better meeting people’s growing spiritual and cultural needs.

Shaping tourism with culture and activating the new format of in-depth tourism

Intangible heritage injects cultural connotation into tourism industry. Intangible cultural heritage projects have profound cultural connotations, unique forms of expression, distinctive regional and national characteristics, and have a good foundation for integrated development with tourism. With the development and maturity of China’s tourism industry, the mode of large-scale landscape construction and resource development has become outdated, and deep tourism, which is closely linked with local society and pays attention to the excavation of historical and cultural heritage, has become a new format of tourism in the new era. In 2023, the Ministry of Culture and Tourism issued the "Notice on Promoting the Deep Integration of Intangible Cultural Heritage and Tourism", proposing that "the organic integration of intangible cultural heritage can further enrich the cultural connotation of tourist spaces such as tourist attractions, resorts, leisure blocks, key villages and towns in rural tourism, and red tourist classic scenic spots, and enhance the cultural heritage", which is a further step for intangible research tours, cultural and sports tours, recreational tours, intangible shopping festivals and intangible food festivals.

Non-legacy energy is transformed into tourism income-generating productivity. In recent years, the "non-legacy+"model has become a new fashion in tourism. For example, the ice and snow carving skills of the provincial intangible project in Heilongjiang Province have attracted visitors from all directions and become a highlight of Harbin’s ice and snow tourism. Shandong Province has released 17 non-legacy tourist routes such as "Spring Folk Art", which has become a new signboard of friendly shandong. Yunnan Dali relies on the March Street National Festival and the promotion activities of "Windy Courtyard" to open cultural and creative markets, pastoral markets and music markets, so that the trend of "following Dali" can revitalize the countryside. Yulin, Shaanxi Province has carefully created the theme tour of "Meeting Yulin, Dialogue with the Ancient City–Sharing the Intangible Heritage Time", and the intangible heritage projects such as Yulin Xiaoqu, storytelling in northern Shaanxi and folk songs in northern Shaanxi are very popular among tourists. Many local experiences in the integration of cultural tourism have verified the strong help of the "non-legacy+"model in realizing the "double harvest" of social and economic benefits in tourism.

The digitalization of intangible cultural heritage helps the transformation from "seeing the scenery" to "entering the scenery". The latest technologies such as digital storage, situational experience, virtual reality and augmented reality in the protection of intangible cultural heritage provide opportunities for cultural relics to speak and intangible cultural heritage to speak, and also promote the upgrading of tourism industry in terms of technology and concept. After years of development, China’s intangible cultural heritage protection has explored a mature digital technology model, forming a multi-modal form such as intangible cultural heritage database and AI intangible cultural heritage experience museum. The integrated application of intangible digital resources is injecting more high-quality and attractive cultural content into tourism in a multi-dimensional and continuous way.

Empowering the people to leave live transmission with their travels.

Tourism provides application scenarios for non-legacy live transmission. Intangible heritage is an important part of China’s excellent traditional culture, and it is the wisdom of life deposited by people everywhere in the long history. Live transmission’s intangible cultural heritage is the connection between the tourism industry and the local historical, social and living aspects. The space reconstruction represented by intangible cultural heritage workshops, intangible cultural heritage experience halls and intangible cultural heritage houses has strengthened the sense of participation and experience of tourists. In this process, popular "punch-in" projects such as interactive demonstrations and experiential teaching have provided conditions for the lifestyle changes of non-genetic inheritors. The presentation of non-legacy projects with historical and life attributes is conducive to enhancing the visibility of local society. At the same time, the tourism industry can give full play to its advantages in revitalizing rural culture and creating jobs for cultural tourism.

Tourism introduces folk power for the systematic protection of intangible cultural heritage. Inheritors are the important subjects of intangible heritage, the masses are the supporters of intangible heritage, and tourists are the potential inheritors of intangible heritage. Promoting the integration of intangible cultural heritage and tourism, and bringing inheritors and people into the tourism industry system can not only narrow the distance between tourists and local people’s daily lives, but also create a tourism ecology with tolerance, friendliness, difference and locality, and is conducive to horizontally promoting the connection between tourism and other formats such as transportation, homestay and cultural creation, and building a new global tourism model. Non-genetic inheritors, rural craftsmen, cultural talents, agricultural professional managers in the field of agriculture, culture and tourism, and other new subjects will join in the cooperation and participate in the planning, management and service of the local tourism industry, which will protect and reserve an orderly talent echelon for non-genetic inheritors and create a good social atmosphere.

Tourism provides an important carrier for intangible cultural heritage to play its value in the times. Tourism, as a contemporary mass lifestyle, can really promote the connection between intangible cultural heritage and modern life, and is especially conducive to improving the intimacy, love and understanding of young people on intangible cultural heritage. When the inheritance of historical context becomes a social consensus, when more and more people, especially teenagers, recognize the charm and value of historical and cultural heritage, our treasures can be entrusted to others and passed down from generation to generation. A healthy tourism market helps to improve the cultural ecology and inherit the historical context. By cooperating with traditional festivals and folk activities, it can convey the intangible ideas, traditional virtues and humanistic spirit, enhance tourists’ sense of identity with Chinese culture and build a strong sense of community of the Chinese nation. The concentrated display of intangible cultural heritage in tourist destinations is an important platform for telling the stories of Chinese excellent traditional culture and promoting Chinese culture to the world.

The integration of literature and tourism has contributed a lot to Chinese modernization.

The integration of intangible cultural heritage and tourism is a vivid practice to promote the creative transformation and innovative development of Chinese excellent traditional culture, and is an active exploration of cultural heritage in the new era "developing in protection and protecting in development". While vigorously promoting the integration of intangible cultural heritage and tourism, we need to pay attention to the following aspects. First, adhere to the priority of protection, develop in protection and protect in development. Based on the cultural core of intangible cultural heritage, adhere to the cultural background of intangible cultural heritage, avoid the damage of excessive commercialization to intangible cultural heritage, and let intangible cultural heritage be better protected and passed down in the integration with tourism. Second, always adhere to the people-oriented principle, stimulate the public’s enthusiasm for non-legacy tourism, connect the protection, inheritance and promotion of non-legacy tourism with the development of global tourism, and make inheritors, villagers and residents become the main participants and beneficiaries of tourism. Thirdly, according to local conditions, we should combine intangible tourism with rural revitalization, urban spatial transformation, cultural and ecological protection areas and national park construction, promote intangible tourism to adapt to the national development strategy in a wider scope and at a deeper level, meet people’s yearning for a better life, and explore ways to promote the creative transformation and innovative development of intangible tourism with China characteristics.

General Secretary of the Supreme Leader pointed out: "Chinese-style modernization gives Chinese civilization modern strength, and Chinese civilization gives Chinese-style modernization a profound foundation." In the new era, the mode of "non-legacy+tourism" is helping non-legacy "live", tourism "hot" and culture "fire". The diversified supply and high-quality development of cultural and tourism integration products will further play the role of non-legacy, serving the present and benefiting the people.

I stand guard for the motherland ｜ Let the red flag fly high on the frontier line.

CCTV News:The Karakorum Plateau, on the northwest border of the motherland, has an average elevation of 5,500 meters, and it is covered with ice and snow for many years, and it is cold and oxygen-deficient. A company commander of the Red Army Division "Tiger Three Company" stationed here in Xinjiang Military Region has a great reputation. He led the officers and men to fight snow, cold and practice elite soldiers in this "forbidden area of life", and built a steel Great Wall on the border defense line to let the five-star red flag fly high. Let’s feel their bloody youth blooming on Karakorum.

In the early morning, the officers and men of a Red Army Division in the Xinjiang Military Region, who are training in the snowy plateau, lined up neatly and had a strict military capacity. In the majestic national anthem, the five-star red flag fixed on the drone slowly rose, and Liu Wei, the company commander of Tiger Company Three, presided over this special flag-raising ceremony.

Liu Wei, company commander of the "Tiger Three Company" of a Red Army Division in Xinjiang Military Region;On the snowy plateau at an altitude of 4,500 meters, I feel very excited every time I see the five-star red flag Ran Ran rising. We stick to the front line of border defense for the peace and tranquility of the great motherland and the happiness and well-being of the people of the motherland.

In the 14 years since he joined the army, Liu Wei has always been full of vigor, and won 13 first prizes in various competitions. In 2017, Liu Wei led a team to participate in the safety environment competition in the international military competition Korla. At the training base with the surface temperature of more than 40 degrees Celsius, Liu Wei led the team members to be fully armed and trained for more than 14 hours every day, and practiced the real skill of "reducing the devil" with quick drug viewing, accurate drug judgment and stable drug detection.

Liu Wei, company commander of the "Tiger Three Company" of a Red Army Division in Xinjiang Military Region;Many players from other countries are veteran players with many years of experience, and all our players are participating for the first time. If we want to defeat our opponents, we must not only have enthusiasm, but also have real strength. We must take them down without hesitation. Only in this way can we defend our national prestige.

In the end, in the chemical reconnaissance of cycling race, Liu Wei broke the world record with a score of 34.95 seconds. His team won the first place in the single event, shooting race and relay race, and won the team championship. Liu Wei was named "the best scout".

In May, 2020, Liu Wei became the company commander of "Tiger Company 3". At the beginning of his tenure, it coincided with the company’s adjustment and reform. Facing this infantry company, which used to rely on "shooting accurately, running fast and throwing far", Liu Wei led the company to complete the system transformation and upgrading around new tactics and new equipment, and launched a new charge.

Liu Wei, company commander of the "Tiger Three Company" of a Red Army Division in Xinjiang Military Region;Honor belongs only to the past. If we want to create new glory, we must clear the honor in our minds, do a solid job in the basic course training of the company, and make every officer and soldier become a top fighter.

Staff Sergeant Li Lujun, a Red Army Division "Tiger Company Three" in Xinjiang Military Region;During that time, the company commander took us to practice on the spot during the day, and gathered the backbone at night to sum up and sort out the problems. Day after day, some new tactics and training methods gradually matured.

Not long ago, a tactical drill started in Karakorum at an altitude of more than 4,300 meters. Restricted by the plateau topography, the red attack was once frustrated. At the critical moment, the "Tiger Three Company" was ordered to make a surprise attack. Liu Wei, the company commander, led the company to drive a new assault vehicle, which quickly penetrated the flank and tore the defense line of the other side in the shortest time.

Liu Wei, company commander of the "Tiger Three Company" of a Red Army Division in Xinjiang Military Region;The protective assault vehicle has the advantages of strong protective ability and fast maneuverability.

Original Serial： How prominent is Hong Jinbao’s family background？ They are all big figures, and the family supports half of Hong Kong Shadow

How prominent is Hong Jinbao’s family background? Each is a big figure in the Republic of China. The family power supported half of Hong Kong’s films. In 1938, Hong Kong produced the first martial arts film "Fang Shiyu Fight the Ring". The director of this film, Hong Ji, is Hong Jinbao’s grandfather, and Hong Jinbao’s grandmother, Qian Siying, is the first generation of Chinese martial arts actresses.

In the late 1940s, Hong Jinbao’s grandparents sponsored Yu Zhanyuan, a Beijing opera master, to establish the Hong Kong Chinese Drama Academy. This academy, in fact, was a place for the troupe and a large number of talents for subsequent Chinese films. Hong Jinbao was one of them.

From Xiao Long to the youngest martial arts instructor in Hong Kong, and now to the big brother of the film industry, the colleague that Hong Jinbao most admires is not his junior brother Jackie Chan, but the kung fu legend Bruce Lee. When the three brothers of Hong Jinbao Jackie Chan and Yuan Biao went to the cinema to watch Bruce Lee movies, Jackie Chan and Yuan Biao both thought that Bruce Lee movies were nothing more than this. Only Hong Jinbao can bet that this is the beginning of a huge change.

Because he felt that Bruce Lee movies had a real fighting feel. Later, Bruce Lee introduced Chinese kung fu movies to the world, and Samuel Hung has been following with an attitude of admiration and appreciation. Therefore, after Bruce Lee left, Samuel Hung launched a tribute to Bruce Lee’s work "Fat Dragon Crossing the River".

He not only imitated Bruce Lee in this movie, but also showed the essence of Bruce Lee’s movements to the fullest. Although the appearance of the two is quite different, when it comes to imitating Bruce Lee, no one can defeat Fatty Hong.

Wonderful not only in front of the stage, can the minister only talk about big things, everyone, I am able to minister. Today we will talk about this "Fat Dragon Crossing the River"!

Video loading…

In fact, Samuel Hung and Bruce Lee are not familiar with each other. He first played a supporting role in Bruce Lee’s works. The two had private contact but not much, but Samuel Hung admired Bruce Lee very much and has been trying to catch up.

In 1978, the era of Bruce Lee had come to an end, and Hong Jinbao became a famous martial arts instructor and producer in Hong Kong. He recruited Ni Kuang, one of the four talents in Hong Kong, as a screenwriter, and wrote the script of "Fat Dragon Crossing the River". The story content is similar to Bruce Lee’s masterpiece "Raptors Crossing the River". But Hong Jinbao played his own brilliance in this movie.

In 1972, Bruce Lee starred in the work "Raptors Crossing the River", which broke the box office records in South East Asia. Six years later, Hong Jinbao, who was supported by Bruce Lee, made a film "Fat Dragon Crossing the River". There is no Bruce Lee here, but there is a tribute to Bruce Lee everywhere. The story begins with a dream. The martial arts design is to restore the classic scenes of Bruce Lee’s films from the action and scene. There are both empty hands and equipment, one-to-one seckill, and one-to-many group scenes. The final replenishment action is still ended in a comedic style. From here, it can be seen that Hong Jinbao’s tribute is not just imitation, but adds a lot of his own creativity.

Hong Jinbao plays the male protagonist Aaron, who is a brain-dead fan of the kung fu star Bruce Lee. He first raised pigs in the countryside, and when he had nothing to do, he lectured the little pigs. If he didn’t like anyone, he had to go up and punch them twice. Under the supervision of his father, Aaron went to the city to join his second uncle. The background of this story is a bit like Bruce Lee’s "Raptors Crossing the River".

There are many fighting scenes in the movie. Hung Jinbao not only referred to Bruce Lee’s action style, but also added the most popular acrobatic martial arts design at that time in the details. It is worth mentioning that Lin Zhengying also appeared in this movie, playing a punk who was beaten. It hurts to watch. In the early years, Lin Zhengying and Hung Jinbao followed Bruce Lee. Later, Lin Zhengying also directed and starred in a tribute to Bruce Lee’s work "Green Hornet", but the box office was not as good as Fat Dragon Crossing the River.

In 1978, Hong Jinbao directed and starred in the "Fat Dragon Crossing the River" after the release, although it is a tribute to Bruce Lee’s works, only received 1.66 million Hong Kong dollars at the box office, but did not set off much waves in the industry, when Hong Jinbao was 29 years old, is a director producer and martial arts director, young and energetic refused to admit defeat, so after the "Fat Dragon Crossing the River", Hong Jinbao worked overtime and drove out a "Mr. Zan and Looking for Qian Hua" before the end of the year. The movie has a full plot and full of interest. The box office 2.86 million Hong Kong dollars, ranking sixth in the year., Now there are still people who regard "Mr. Zan and Looking for Qian Hua" as a Wing Chun teaching film.

At that time, Hong Jinbao was talented, not only launched a number of action movies, but also showcased his skills in comedy, ghost movies and other fields. However, Hong Jinbao’s favorite was literary films. At the peak of his career, Hong Jinbao opened a company to launch many literary films, and even pulled his junior brother Jackie Chan to play a "Dragon’s Heart". Unfortunately, the Hong Kong film market was like a big wave, and good-looking films emerged in an endless stream, but few audiences could remember. Hong Jinbao’s career began to lack stamina in the 1990s.

Until now, if you want to talk about Hong Jinbao, the people who can talk to you may have all married and started a business, and few people remember how flexible and powerful Hong Fatty was back then. With the aging of a generation, today’s film and television industry has changed. It seems that few people stick to the bottom line and take their works and audiences seriously.

　　How to deal with the increasingly tough US policy towards China?

　　It should be noted that the interests of China and the United States have been deeply intertwined. I believe that a conflicting and confrontational Sino-US relationship is not in the interests of either side. In addition, there is no way to deal with new problems in the context of globalization with the old thinking of the Cold War.

　　I believe that the essence of China-US economic and trade relations is mutually beneficial and win-win. Therefore, we hope that the two sides will continue to step up consultations and reach a mutually beneficial and win-win agreement.

　　What are the reasons for formulating the Foreign Investment Law?

　　The formulation of the Foreign Investment Law is to innovate the legal system for foreign investment, replace the "Three Laws of Foreign Investment" (the Law on Sino-Foreign Joint Ventures, the Law on Foreign-funded Enterprises, and the Law on Sino-Foreign Cooperative Enterprises), and become the basic law for the utilization of foreign capital in our country in the new era.

　　● The "Belt and Road Initiative" has put some countries in a "debt trap"?

　　The "Belt and Road Initiative" adheres to the principle of extensive consultation, joint construction and sharing, and also adheres to the market-oriented operation model.

　　Whether it is project selection or investment and financing cooperation, all decisions are made jointly by the participating parties.

　　China attaches great importance to the issue of debt sustainability and will not impose it on others in project cooperation, let alone create any traps.

　　Will China’s rising defense spending pose a threat to other countries?

　　China has always adhered to the path of peaceful development and pursued a national defense policy that is defensive in nature. China’s limited defense expenditure is solely for the purpose of safeguarding national sovereignty, security and territorial integrity, and will not pose a threat to other countries.

　　Will the Personal Information Protection Law be submitted for review this year?

　　The Standing Committee of the National People’s Congress has included the formulation of a personal information protection law in this legislative plan, and relevant departments are working hard to study and draft it, with a view to its early enactment.

　　Important progress has been made in the case of Canadian national Michael Kovrig’s suspected crime

　　According to the relevant departments, since 2017, Michael Kovrig has often entered the country on ordinary passports and business visas, and has stolen and spied on sensitive information and intelligence in China through connections in China. Michael Peter Todd is an important intelligence relationship of Michael Kovrig and provided intelligence to him. Kang’s behavior is suspected of stealing and spying on state secrets and intelligence abroad, which has seriously violated Chinese law.

The vast universe adds another ＂China star＂, let us remember this group of lovely Shanghai astronauts when looking at the starry sky

From today, there is another Chinese satellite in the vast space. In the early morning of November 15, the fourth star of our country’s second-generation polar-orbiting meteorological satellite Fengyun-3 was successfully launched in Taiyuan. And this star, like the other 15 Fengyun meteorological satellites launched by our country, embodies the glory and dream of Shanghai astronauts.

?

Compared with its three "older brothers", Fengyun-3D satellite can be said to have undergone a reborn change. A variety of payloads have been upgraded, and infrared hyperspectral atmospheric detectors, hyperspectral greenhouse gas monitors, and wide-angle aurora imagers have been added, thus gradually meeting the growing new needs of atmospheric detection accuracy, greenhouse gas monitoring capabilities, and comprehensive space environment detection capabilities in the meteorological field. At the Shanghai Academy of Aerospace Technology, the reporter heard the story behind this brand new "China Star".

?

Busy as if obsessed

The Fengyun-3 D-star is loaded with a total of 10 payloads. Compared with the C-star, the D-star has added 4 payloads, and there are 2 that have improved performance and upgraded. Many people think that the Fengyun-3 D-star is a mature model, but the indicator of the 6 new payloads is to reach the international advanced level. The technical status is complex and the development progress is extremely tight.

?

"The high-precision 250-meter split window of the medium-resolution spectral imager is the first in the world, the signal-to-noise ratio of the hyperspectral greenhouse gas monitor in the same spectral range is twice as high as that of GOSAT, the infrared hyperspectral atmospheric detector is consistent with the CrIS index, and the wide-angle aurora imager and ionospheric photometer are both developed for the first time in our country…" Li Yefei, the general director of Fengyun No. 3, used a series of first conveys the extraordinary "origin" of the D star.

?

The six new loads all start from the plan, go through the initial prototype development, and then go through the normal development. The determination of each technical status has to go through countless technical coordination. In the project implementation stage, each load has to sign the interface data sheet, and each load has mandatory inspection points, calibration tests, and ring mold tests.

?

"Sometimes it’s like being obsessed with something all day long. If you say you go to work overtime, you go to work overtime, and if you say you go to work at home, you leave. We really don’t understand." Zhao Qichang, the chief designer of Fengyun No. 3 D star payload, missed the first enrollment of his three-year-old son while working overtime. Faced with his family’s complaints, he can only make up for his "sins" by doing more housework and smiling more.

?

It cannot be looked down upon abroad

With so many new payloads facing such a short development cycle, the progress of the whole satellite is facing challenges, and the progress of the infrared hyperspectral atmospheric detector and the medium resolution spectral imager is particularly tight. "In the first half of 2015, we had to go to the payload unit every day to follow the production, and over time, this batch of designers and the payload unit designers also established a special friendship." Zhao Qichang recalled this period of time deeply.

?

The biggest feature of the Fengyun-3 D satellite data is the global broadcast. Scientists in the global meteorological field are using the Fengyun-3 data, and any problems will be exposed in front of people all over the world. Therefore, the user’s product quality and data quality requirements for the D satellite can be described as "abnormal", from data preprocessing to data application are unmatched by other satellite users, which requires the team to also have data processing capabilities and cannot be underestimated by foreign countries.

?

The Shanghai Aerospace Technology Team started from the original code of the data to analyze, calculate the sensitivity, signal to noise ratio, calibration accuracy, stability, linearity of the instrument, etc., and compare, discuss, negotiate, and finally agree with the user and the load undertaking unit. Users also often praise the Fengyun team as a generalist, not only understanding machines, heat, light, electricity, magnetism, and mechanisms, but also data processing, which is really amazing. However, these are all completed under the condition that the Fengyun team is understaffed. With such a limited number of people, it is really not easy to be both "father" and "mother". But when the satellite is operating stably in orbit, the payload data plays a role in the national economy and people’s livelihood, and international colleagues talk about the evaluation of Fengyun-3’s significant contribution to the world’s numerical weather forecasting, all the ups and downs in the process are nothing.

?

Overcoming micro-vibration difficulties

Fengyun-3 D satellite is loaded with more than ten loads and more than ten moving parts at the same time. The abnormally complex vibration environment leads to an abnormally prominent contradiction in the dynamic compatibility of the star. If you don’t pay attention, the wish of one-star multi-function will not only not be realized, but multiple loads will interfere with each other. In particular, the loaded interferometric infrared hyperspectral detector is the first application on our country’s low-orbit remote sensing satellite. It has the advantages of high spatial resolution and high spectral resolution. Even small vibrations greatly reduce its performance.

?

"In order to solve the dynamic compatibility problem of multi-load coexistence, provide an ultra-quiet working environment for sensitive load detectors, and improve the accuracy of infrared hyperspectral load detection, we developed a micro-vibration monitoring and suppression system, and applied the’liquid damping vibration isolation ‘technology on domestic remote sensing satellites for the first time to achieve resonant peak and high-frequency vibration suppression." Liu Xingtian, the general development unit of Fengyun Satellite, Shanghai Aerospace 509 Institute, is also a direct participant in the research of micro-vibration monitoring and suppression technology, and has a fresh memory of the process of micro-vibration research.

?

After the research and demonstration of the on-board dynamic spectrum characteristics, the potential mutual interference between the loads was effectively avoided. At the same time, the development of the relaxed "liquid damping vibration isolation" technology can not only effectively control the magnification at the resonance peak, but also attenuate the high-frequency vibration by more than 90%, overcoming the technical problems of traditional passive vibration reduction. At the same time, the research team repeatedly carried out a series of comparison tests, parameter adjustment one by one, and test verification one by one, finally ensuring the harmonious coexistence of multiple loads in orbit and ensuring the imaging performance of the satellite.

?

As a new generation polar-orbiting meteorological satellite in our country, since the launch of Fengyun-3 in 2008, its satellite remote sensing data has provided an important basis for national and local government decision-making. It has played an important role in the meteorological service guarantee of major events such as the "Belt and Road Initiative" International Cooperation Summit Forum, the 13th National Games, the 9th BRICS Leaders’ Meeting, and the 19th National Congress of the Communist Party of China.
