Recently, AITO Wujie M5 Advanced Intelligent Driving Edition (Wujie M5 Intelligent Driving Edition) has carried out a large-scale in-depth media test drive throughout the country, showing its hard-core strength in the field of NCA intelligent driving in urban areas for the majority of media friends. Wenjie M5 Intelligent Driving Edition is equipped with HUAWEI ADS 2.0 Advanced Intelligent Driving System (HUAWEI ADS 2.0), which shines brilliantly in the actual urban sections and gives a perfect performance of nearly perfect score. At the same time, the powerful power system of the M5 Intelligent Driving Edition and the top experience of HarmonyOS Intelligent Cockpit 3.0 make its name "Double Intelligent Ceiling" worthy of the name.

You can "see" the road without relying on high-precision maps.

The M5 intelligent driving version of Wenjie is equipped with HUAWEI ADS 2.0, which realizes the NCA intelligent driving navigation without relying on high-precision maps. Recently, Yu Chengdong, managing director of Huawei, CEO of BG and CEO of BU, a smart car solution, said that the M5 version of Zhijie has started the nationwide large-scale delivery of new cars, and the latest version of the system will be officially upgraded by OTA at the end of June, bringing better smart driving experience to users. It is expected that in Q3 this year, 15 cities will be opened for commercial use without maps, officially opening a new era of high-level intelligent driving in urban areas.

Thanks to the multi-sensor fusion perception system, Wujie M5 Intelligent Driving Edition combines with road prediction neural network to realize the correlation of traffic elements, topological reasoning of road structure, and the matching between navigation map and real road, so that cars can "see" the road. HUAWEI ADS 2.0 can help drivers get rid of the trouble of taking care of mobile navigation while driving, give full play to the advantages of NCA’s intelligent navigation function, and realize a wider range of point-to-point high-order intelligent driving on the road, which is not only safe and reliable, but also makes driving easier.

The sense of security of intelligent driving also comes from accurate identification and accurate prediction of potential dangers. Not only in the highway section, but also in the urban section where people commute on weekdays, in the face of the scene of traffic and mixed people and cars, obstacles in the white list such as people and cars can be accurately identified by the fusion perception BEV bird’s eye view network in HUAWEI ADS 2.0 under the "God’s perspective". On this basis, abnormal obstacles such as water horses, mounds or sundries, fallen trees, etc., which are not listed on the white list, can also be pioneered by GOD’s general obstacle detection technology in the industry, and accurately capture and avoid risks through the simultaneous input of lidar and visual meeting.

After AI training, Wenjie M5 Intelligent Driving Edition has built a rich scene library to deal with various difficult scenes. When the right-hand vehicle overtakes, the left-hand vehicle comes from the rear, and there are big cars driving in front and behind, etc., on the premise of ensuring safety, the vehicles can make their own decisions and take actions such as slowing down and merging and speeding up overtaking. Whether it’s a "ghost probe" where the other side’s car is dazzling and the driver’s vision is blocked, or it encounters bad weather and insufficient light, HUAWEI ADS 2.0 can cope with and resolve it, and incorporate practical experience into its own database, and continue to iterate and optimize, becoming more and more like an "old driver" with rich practical driving experience.

Intelligent at the same time, performance is not inferior.

Not only that, the M5 version also has a 4-second acceleration performance, which brings strong power output to drivers. At the same time, its super-long cruising range reaches 1400km+, providing users with more lasting driving pleasure and convenience. Wenjie M5 Intelligent Driving Edition upgraded the all-aluminum chassis, replaced it with 1.5T all-aluminum four-cylinder range extender 4.0, and successfully "slimmed down" 20kg. Comprehensive weight reduction and HUAWEI DriveONE intelligent electric drive platform, combined with front double wishbone and rear multi-link suspension configuration, provide sports car-level handling performance.

Under the condition of full fuel and full charge, the maximum comprehensive cruising range of the extended range version (rear drive) of the M5 intelligent driving version is 1425km, and the pure electric cruising range of CLTC is upgraded to 255km. Even if you travel across provinces in go on road trip for a long distance, you can make sure that you don’t need to replenish energy frequently. The Wujie M5 pure electric intelligent driving version is equipped with a golden four-wheel drive combination consisting of a front AC asynchronous motor and a rear permanent magnet synchronous motor, which gives perfect consideration to power and economy. HUAWEI DATS dynamic adaptive torque system also greatly reduces the shaking of vehicles on bumpy roads, greatly improves driving comfort, and brings users top-level driving control, stronger power, lower energy consumption, quieter driving experience and more comprehensive safety protection.

On the other hand, in terms of passive safety, the M5 intelligent driving version is armed to the teeth. Advanced body structure design and high-strength body materials make the vehicle more sturdy and stable, and provide reliable passive safety guarantee for drivers and passengers. No matter what kind of accident, passengers can always get the most effective protection.

This large-scale national media in-depth test drive, asked the M5 version of the smart drive to get a wide range of good feedback from the media, affirming its excellent smart drive experience and excellent product strength. Nowadays, the M5 version of Zhijie has been delivered nationwide on a large scale, bringing consumers a brand-new experience of high-level intelligent driving.

　　Recently, "fitness live broadcast" has once again become popular on the internet, and the trend of "staying at home fitness" has revived. In the face of the epidemic, more and more people in Shanxi choose to strengthen their physique and adjust their mentality through physical exercise, and many people’s lives have also changed because of exercise. Xu Jun/Zuo (Xinhua News Agency)

　　This year’s "May Day" holiday, the "scenery" in the circle of friends is very different from previous years: some people go outdoors and enjoy the comfort brought by camping; There are still a large number of people who continue to stay at home and follow Liu Genghong in the live broadcast room to dance the "Compendium of Materia Medica". Beginning in early April, live fitness and shuttlecock jumping seemed to be unavoidable topics, and many "Liu Genghong boys" and "Liu Genghong girls" punched in the clouds on time.

　　In recent years, influenced by the repeated epidemic in COVID-19, fitness, as a part of the consumer market, has been constantly changing, and the home scene has been fully developed. From the launch of black technology products such as fitness rings and mirrors, online courses have been laid out on fitness platforms one after another, and a group of fitness IP figures such as Saturday Ye, Pamela and Liu Genghong quickly iterated, and the wave of "cloud fitness" for the whole people has been heated up.

　　However, with the topic of "Liu Genghong boys and girls jumping into hospitals" rushing to the hot search, many people in the industry reminded that we must pay attention to the intensity of training, do what we can, and don’t blindly follow the practice.

　　"Cloud Fitness" appears "from person to person", so it is most important to choose the right one.

　　"You jump ‘ Compendium of materia medica ’ Is it? " Lin Lin, a post-90s Chengdu girl, found that the greetings of friends around her have changed recently. She told the reporter of Zhongqing Daily and Zhongqing.com, "It seems that overnight, Liu Genghong has become everyone’s fitness instructor, and sometimes she sees her friend ‘ Trembling ’ When I came, I knew that she skipped exercise yesterday. "

　　In Lin Lin’s view, the "person-to-person" follow-up phenomenon, dubbed by netizens, has become a "new social way" for young people. As a fitness enthusiast, Lin Lin will follow the live broadcast of Liu Genghong to exercise whenever she has time.

　　"Before the fire broke out in Liu Genghong, many online celebrity fitness bloggers had sprung up on various platforms with various courses. Choose courses that you can follow and like, and train regularly. You don’t have to be hard on yourself. After all, fitness is something that can release your stress. " Lin Lin said.

　　In fact, long before Liu Genghong, Pamela, a foreign fitness blogger known as "Humanoid AI", set off a trend of heel-training in China. Sharing and practicing courses has also enabled many offline fitness coaches and fitness enthusiasts to switch to the network and become a fitness blogger with many fans. Interestingly, Olympic champions such as Wu Dajing, Ren Ziwei and Su Bingtian started to participate in the "National Fitness Program" launched by some platforms during the "May 1" holiday this year, taking everyone to exercise together.

　　"Cloud Fitness" swept the social platform, which is obviously a red sea.

　　More and more stars, athletes and fitness bloggers give free classes, which seems to give everyone a reason to "move". Skipping rope with the Keep course and practicing boxing in the offline fighting hall, Yang Xiaoyi, who works in Beijing, happily got a fitness report card: he lost 30 pounds in five months. She told the reporter of China Youth Daily and China Youth Network that after leaving the original company in early March, "Cloud Fitness" made her have a lot of happiness.

　　Although she didn’t follow Liu Genghong’s "Shuttlecock Exercise", Yang Xiaoyi will also look for a fitness blogger who suits her on social platforms. When screening and practicing courses, she will pay special attention to the cases and comments posted by bloggers. "Generally, we will verify whether the courses are scientific or not, and we will also look at the interest chain behind bloggers. If bloggers just want to bring goods, sports are not suitable for themselves, and they will be ruled out."

　　A fitness practitioner who didn’t want to be named reminded: "The chaos that can’t be ignored is that some bloggers exaggerate the effects of some actions in order to pursue traffic and cater to the market. Myth ’ . Returning to the initial heart, fitness bloggers should recommend sports areas that they are good at, and give professional guidance to people who love you, so that everyone can fall in love with sports, not get hurt, and enjoy the joy of sports. "

　　"Liu Doby is not very funny", the owner of bilibili Sports and Fitness UP with millions of fans, suggested that you should know your physical condition before fitness and do what you can; During the fitness period, you should also learn some fitness science knowledge properly, so as to better distinguish and choose the fitness bloggers and exercise methods that suit you. "Exercise and fitness should be done slowly, and it is urgent."

　　"Cloud Fitness" should also have "dry goods", and it can also train users for offline fitness.

　　Exercise has become a daily habit of Liu Doby because of his contact with fitness during the post-operation rehabilitation period. She worked as a fitness instructor for 7 years before becoming a full-time fitness UP master. Liu Doby admits that she likes the feeling of face-to-face communication with students offline.

　　"Until the beginning of 2021, because of vocal cord injury, I tried to share my own dancing and training videos on various platforms during my rest at home. I didn’t expect to gain a lot of attention." After more than two months, Liu Doby chose the "main attack" online.

　　Without the face-to-face atmosphere of offline fitness, how to attract young people to like the content of online courses is particularly important. Liu Doby told the reporter of China Youth Daily and China Youth Network that she was very opposed to "crash" and body anxiety, and hoped to convey more emotional value in online courses.

　　For example, let everyone feel that exercise and fitness can actually be very happy, exercise can also be integrated into the dance and music that everyone likes, and it can also make you more active and energetic in your work and life. What makes her happy is that "the fitness studio in Liu Genghong is actually providing emotional value for everyone, which deserves more people to see. Fitness is not only for beauty, but also for happiness and decompression, especially in the home mode, which may require the release of emotions. "

　　"Early-made follow-up videos are more like ‘ Translator ’ , to help you do password guidance, safety tips and action explanations. But anyone can do the video of translating and practicing actions, and I still have to do my own original content. " Liu Doby admits that compared with other bloggers, her courses are "relatively small", and there will be no high-intensity movements. They are all fitness and fat-burning dances that she also likes very much. However, she will also arrange more interesting courses according to the suggestions of netizens.

　　Yan Shuaiqi has been a fitness instructor for two years and a course designer on the Keep platform. Now he has become a sports UPP owner with nearly 2 million fans. He observed that since the outbreak of the epidemic, when gyms were closed, many fitness coaches turned online, and some coaches who had done well became full-time bloggers.

　　In view of the fact that the course audience is mostly male users, he classifies his courses according to fat reduction, single part training, posture adjustment, home training and novice application. In his view, "doing sports courses is the same as being a brand. The content must be focused and it is impossible for all people. We should thoroughly understand the needs of the audience we are facing, launch the response content according to the needs, and also explain what everyone needs ‘ Dry goods ’ And tips for safety training. "

　　At the beginning of this year, Liu Doby obviously felt that many fitness instructors around her were testing the water from the media, and some institutions invited her to share and train from the media operation. In her view, the popularity of "cloud fitness" not only makes online courses richer and more high-quality, but also promotes the development of the fitness industry.

　　"Maybe some people will prefer online courses, but some people will develop fitness habits through online courses. After the epidemic, they will turn to offline fitness and bring drainage to offline fitness venues. More importantly, there are more and more online quality courses, which will also force offline fitness instructors to be more professional. " Yan Shuaiqi also believes that the increase of online quality courses will promote the better development of the fitness industry. "The more people stay at home to exercise, the more people will be willing to go offline to exercise after the epidemic."

　　Running a gym in Beijing makes Wang Liping feel very interesting. "Although the epidemic is repeated, the students in the gym will follow the fitness bloggers for daily exercise, but they are also eager to train in offline venues. The feeling and atmosphere that everyone is sweating together, and you are fighting with me, can’t be achieved by online live broadcast. " However, she also saw the fierce competition in the fitness market from online to offline. "After surviving the epidemic, we will continue to improve our courses and services and develop rapidly with the fitness industry."

　　Wu Guanghui, chief designer of Comac C919 and ARJ21, has won the national special prize for scientific and technological progress and the first prize for national defense scientific and technological achievements. A key model won the first prize of China Aviation Industry Corporation I and the first prize of the National Defense Science, Technology and Industry Committee.

　　"Many aircraft parts are made in China and fly in the sky every day. C919 has gone through nearly seven years, and has done a lot of design, calculation and experiments. I am definitely willing to take this plane first. "

　　— — Wu Guanghui

　　These days, in the commercial aircraft test center of China Commercial Aircraft Corporation, the newly-built Zhuqiao test hangar in Pudong is spacious and bright. In the hangar, the landing gear that originally supported the domestic large passenger plane C919 was all put into the landing gear cabin, and three air springs like "jacks" lifted the plane into mid-air. What is going on here is the ground resonance test and modal coupling test of the whole aircraft that must be completed before the first flight, which means that the C919 has officially entered the final sprint stage before the first flight.

　　C919 is a domestic large passenger plane independently designed and developed by China. It is a short-haul single-aisle narrow-body passenger plane with more than 150 seats. In the future, it will compete with internationally renowned commercial aircraft such as Airbus 320 series and Boeing 737 series for orders. The manufacturer China Commercial Aircraft Co., Ltd. recently announced that the C919 plans to make its first flight in the first half of 2017 and will fully launch the wide-body passenger aircraft project. It can be said that after nearly 10 years of hard work, China people’s dream of "big plane" will soon become a reality.

　　① Rigorous test to ensure safety.

　　To fly into the blue sky, a plane must first practice a pair of steel bars and iron bones. For the C919, which carries the dream of a big plane for Chinese people, the significance of the test is even more significant. This is the first large passenger plane made in China, and its safety cannot be lost.

　　For this reason, C919 has undergone a series of tests like "torture". Among them, the 2.5g static test of the whole aircraft started in early November last year is the most severe and significant one since the birth of the C919.

　　This test mainly tests the strain and deformation of the "skeleton" of the body under constant external loading. In layman’s terms, this kind of test is to let the aircraft simulate the stress situation when challenging air flight on the ground, and go beyond the natural limit to verify how much force the aircraft can bear.

　　Before the start of the experiment, the researchers covered the whole body with white adhesive tape, which is a resistance strain gauge that can sensitively measure stress and strain close to the surface of the body, just like doing electrocardiogram for the plane. During the test, the load starts to rise at the level of 5%, and the load must be kept for 3 seconds every time. "The structure must be able to withstand the ultimate load for 3 seconds without damage." Zhou Liang Dao, deputy chief designer of the C919 passenger plane, said that the preparation behind the team took more than 300 days for this short three seconds.

　　With the continuous loading, the aircraft began to show obvious external reflection, and the wing began to tilt up a little. Finally, when the load reaches 100% of the test outline, the wing tip tilts up to nearly 2 meters, which is highly consistent with the strength analysis before the test, which shows that the test is successful and its strong "bones" and body are enough to support flying into the blue sky.

　　This is just a small step in the long March before the first flight of the plane. A passenger plane has to complete 13 static tests in 48 working conditions, including pressurization in the booster cabin, front lifting connection, main lifting connection, whole aircraft condition, vertical tail and rudder, as well as "three-bird test" such as iron bird, copper bird and electric bird and joint test of the whole aircraft system. Therefore, researchers have made independent innovations in system integration experiments.

　　In the comprehensive test hall of Shanghai Aircraft Design and Research Institute, the iron bird test-bed with little difference from the C919 real machine looks like an eagle with wings spread and its tail stuck high. Don’t underestimate this test-bed. Its full name is "Integrated Test-bed for Flight Control Hydraulic System", which mainly tests the landing gear, wings and other mechanical systems of aircraft. In order to ensure the authenticity of the system test, the iron bird test-bed is designed according to the 1:1 ratio of the real aircraft, so that the mechanical installation interfaces of the flight control, hydraulic and landing gear systems are the same as those of the aircraft.

　　Next to the Iron Bird Test Bench, there is also a "Copper Bird" that tests power supply systems such as power generation and distribution, and also restores the real state of the machine to 1:1 for equipment installation. "Iron Bird", "Copper Bird" and the avionics system test called "Electric Bird" will eventually be all connected, thus forming a "three-bird joint test" to simulate the state of the aircraft.

　　In the experiment, researchers conducted a comprehensive test on the aircraft system. Take the avionics system as an example. At most, there are more than 100,000 parameters in a test. These parameters should be tested one by one to find out the possible omissions in the design. "Our goal is not to take the fault to the sky." Yu Shenghui, senior engineer of the General Aerodynamics Department of Shanghai Aircraft Design and Research Institute, said.

　　According to the plan, six testing machines are carrying out joint testing of the whole machine system, and customer service engineering and airworthiness work are also being carried out simultaneously.

　　②C919 is genuine China goods.

　　As the first large passenger plane with completely independent intellectual property rights in China, C919 has been frequently questioned since it was established in 2006: an aircraft whose engine, avionics core processing system and some materials all depend on foreign products or technologies, why should it be said to be "made in China"?

　　In fact, to evaluate the innovation of C919, we may need to draw lessons from a fairy tale named Pony Crossing the River. This story is about a pony crossing a river. A cow next to it said, "The water is very shallow, just without a calf, so you can cross it." But the squirrel in the tree said, "The water is deep and will drown." So, is the river deep or shallow? Finally, the pony got off the river by himself and carefully waded to the other side. It found that the river was neither as shallow as the cow said, nor as deep as the squirrel said. The same is true for the development and innovation of C919. Everyone should not only see the major innovations achieved in the process of aircraft development, but also objectively admit the existing shortcomings.

　　According to international standards, judging whether an airplane is made in China or assembled depends on whether it meets three conditions. 1. Who owns the property right of the whole machine? Second, who is the core team to develop the whole machine? Third, who holds the key link in the development of the whole machine? For C919, the answer to these three questions is China.

　　The person in charge of Comac in China said that the property right of the C919 is owned by Comac in China. The team of Comac in China is the core of the development, and the key links such as aircraft design, final assembly, test flight and sales are in the hands of Comac in China.

　　As for foreign companies providing parts or technology, this is a common thing in the global aviation manufacturing industry. Aviation manufacturing giants such as Boeing and Airbus also use foreign products on many key components when developing aircraft.

　　However, for equipment like engines, the C919 chose the LEAP-X1C engine jointly developed by the United States and France, which is the only foreign starting power device selected by the C919. It should be said that the engine is indeed a major constraint in the development of China’s large aircraft, and it can only be sought from people at present. However, I believe that in 10 to 15 years, China will be able to develop its own advanced aero-engine for large aircraft.

　　③ Have a number of scientific and technological innovations.

　　Experts said that the C919 was completely designed and integrated independently, with outstanding technical indicators. It is the persistent innovation of researchers who have sharpened their swords for ten years that has led to the high-tech C919, which integrates many key technologies.

　　However, what did C919 look like when it was approved as one of the 16 major projects in the national medium-and long-term science and technology planning in January 2006? What difficulties may be encountered in the development? Due to the limitation of western aviation powers in technology introduction, China researchers have no idea and can only cross the river by feeling the stones.

　　In November 2008, the C919 project was launched. A large passenger aircraft joint engineering team composed of 468 experts from 47 domestic and foreign units, plus a large passenger aircraft expert consulting group composed of 20 academicians and experts, started from sketches and gradually sorted out the first batch of 14 special technical research projects that need to be started.

　　Among these key technologies, there are several that must be mentioned. For example, the "supercritical airfoil" that makes airplanes more fuel efficient. A large passenger airliner is an out-and-out "oil tiger". In order to reduce fuel consumption, the wing design of C919 uses a supercritical airfoil, which improves the cruise aerodynamic efficiency by more than 20% and reduces drag by about 8%.

　　Another unique innovation is the adoption of the third generation Al-Li alloy materials. It is the first time in China that the world’s advanced third-generation Al-Li alloy materials are widely used in the main structure of C919. Compared with ordinary aluminum alloy, this lightweight metal material with high damage resistance has greater strength and lighter weight under the same strength, which is very important to realize the weight reduction of aircraft structure and greatly improve the service life of aircraft.

　　In addition, as the "brain" of the C919, the avionics system of the aircraft has realized "giving all the work to the network". Compared with the old version of the network, which was widely used before but had limited bandwidth, the new aviation bus communication protocol adopted by C919 not only has high bandwidth but also shares resources, which means that the signals that originally needed to be transmitted through several cables can now be transmitted by one cable. Experts said that this is like we need to run 10 trains from A to B, but we don’t need to build 10 railways. We only need a set of double-track railways and a reliable signal system.

　　According to Wu Guanghui, the chief designer of C919, the developers have planned 102 key technical problems, and many advanced materials have been applied on a large scale in domestic civil aircraft for the first time. The development process of millions of parts and airborne systems is highly parallel. In order to overcome these technical difficulties, 22 provinces and cities, more than 200 enterprises, 36 universities and hundreds of thousands of industrial personnel participated in the development of C919 large passenger aircraft, and 16 material manufacturers and 54 standard parts manufacturers including Baosteel became suppliers or potential suppliers of large passenger aircraft projects.

CCTV News:On June 10th, Kim Jong-un, the top leader of the DPRK, took a special plane provided by China to Singapore, where the DPRK-US leaders met. On the 12th, a meeting was held at the Capella Hotel on Sentosa Island. This is the first meeting between the incumbent leaders of the DPRK and the United States in history.

Which plane did Kim Jong-un fly to Singapore? The international media launched a heated speculation on this issue, and the answer was revealed on the afternoon of the 10th. According to the airport photos released, Kim Jong-un was aboard the Boeing 747 of Air China.

　On June 10th, Kim Jong-un (former), Chairman of the DPRK Council of State, arrived at Singapore Changi Airport.

South Korea’s MBC TV reported on the 10th that it was the first time for North Korea to visit such a distant country by plane. North Korea invested three planes for Kim Jong-un’s trip to Singapore: Goshawk-1, a chartered Boeing 747 of Air China, and Il -76 transport plane for transporting logistics. According to Korean media observation, at 8: 30am on the 10th, Air China plane took off from Shun ‘an Airport in Pyongyang, numbered CA122, and its destination was Beijing. After an hour’s flight, the plane did not land after arriving over Beijing, but changed its flight number and destination. The flight number was changed to CA61 and the destination was Singapore. Almost at the same time, "Goshawk-1" also took off from Shun ‘an Airport in Pyongyang.

South Korea’s "National Daily" said on the 10th that China provided "special guarantee" for Kim Jong-un to go to Singapore. Not only did Kim Jong-un take the China special plane, but most of the whole flight was arranged in China’s airspace.

Why did Kim Jong-un use a Chinese plane to travel to Singapore? Clever response from the Ministry of Foreign Affairs

Kim Jong-un, the top leader of the DPRK, went to Singapore by special plane provided by China, which aroused great concern from foreign media. At the regular press conference of the Ministry of Foreign Affairs of China held on June 11th, questions about the special plane were asked three times.

Media: It is reported that on the 10th, Kim Jong-un, the top leader of the DPRK, took a special plane provided by China to Singapore, where the DPRK-US leaders met. May I ask Chairman Kim Jong-un why he used the Chinese plane? What is China’s position on this?

Geng Shuang: At the request of the DPRK, China Civil Aviation provided relevant services for the DPRK delegation to go to Singapore.

Media: Did North Korea ask China to provide flights, or did China offer them?

Geng Shuang: You didn’t listen to my answer just now, did you? The first thing I said just now was, at the request of the DPRK.

Media: Regarding the plane, did China lend it to the DPRK, or did China charge the relevant fees for chartering? Don’t ask me to ask the relevant departments. We think the Ministry of Foreign Affairs is the competent department.

Geng Shuang: My answer is the same as just now. At the request of the DPRK, China Civil Aviation provided relevant services for the DPRK delegation to go to Singapore.

In earlier reports, some South Korean media speculated that Kim Jong-un would take North Korea’s "Air Force 1" — — "Goshawk 1" flew to Singapore. It is reported that when Kim Jong-un visited Dalian, China on May 7, he took the "Goshawk 1". "Goshawk 1" has a five-pointed star pattern symbolizing communism printed on the tail, and the words "Democratic People’s Republic of Korea" are written on the top of the front of the plane, and the national emblem of Korea is also painted.

　　February 21st, the 28th day of aid to Hubei. It’s raining again in Wuhan.

　　When I went to work this morning, it was raining outside. I bought a loving little pholiota adiposa from the door of the hotel and hurried to work.

　　There are obviously more cars and even buses on the road around Jinyintan Hospital. There are also many people standing at the bus stop in the distance. Wuhan has not lifted the "closed city", so I guess they may be the medical staff in the living room (Fangcang Hospital) of Wuhan, and they have to take the shuttle bus back to their place of residence. You have worked hard, too.

　　When I changed my work clothes, I just arrived at the doctor’s office and saw a big plastic bag in front of Professor Zhou. When everyone was almost here, Professor Zhou opened the plastic bag, which contained several sets of protective clothing and swimming glasses. Professor Zhou said excitedly that this is a material sent to him by a Shanghai primary school student. Primary school students and their parents bought eight sets of protective clothing and donated them all. I hope everyone will be safe. I don’t know what kind of twists and turns this child and his family have gone through before they can collect protective clothing under the unified management of protective materials. From the childish handwriting of children, we can see the people’s care and love for us and the future of our motherland. The head nurse said that they also received materials from an aunt in Shanghai. The circle of friends said that the people of Shanghai "borrowed" us to Wuhan! The arrival of batches of materials expressed their care and they looked forward to our early and safe return. Everyone is very touched!

　　Next, it’s the shift handover time. After the shift handover, Team Zheng once again reiterated the safety issue, and let us carefully read the formula of wearing and removing protective clothing in Ruijin Hospital, so that each team member can remember four "musts": be highly vigilant, be strict in management, be sure to standardize the process and be cautious! Yes, we have been helping Hubei for 28 days, and now it is time to get tired and relaxed easily. We must cheer up and do a good job in protection and other work seriously and rigorously.

　　Today, I followed Professor Zhou into the isolation ward for rounds. After checking the room, the nurses have prepared a full set of tracheal intubation devices. After the patient was fully calm, Professor Zhou made a nasotracheal intubation under the guidance of bronchoscope. I admire his proficiency. Today, after working as an assistant and observing the actual operation, my heart is much more stable. As the saying goes, "more skills don’t weigh me down", and I learned new skills today. Professor Zhou completes tracheal intubation, adjusts the ventilator mode and parameters, and observes the patient’s vital signs for a while, which makes me feel more at ease.

　　Our group discharged a patient today. His symptoms improved, his nucleic acid test was negative continuously, and his lung CT examination turned better. According to the current process, patients need to be isolated at home for 2 weeks after discharge. However, the patient expressed the difficulty of his family’s housing shortage, and he was worried that it would affect other family members. We reported to the medical department of the hospital. Through coordination, when the patient leaves the hospital today, his community will send a car to pick him up and observe him in isolation at a nearby hotel for two weeks. I told him the two-week and four-week follow-up plan after discharge. Tomorrow and the day after tomorrow, there may be patients in our group discharged from the hospital. Spring has arrived in the intensive care unit.

　　In the afternoon, three columns of Chinese characters were posted in front of the first important door of our isolation ward. Maybe it will become a small scenic spot in Jinyintan Hospital in the future. Everyone lined up to take a photo with Professor Zhou, and I quickly lined up. Wuhan, come on! China, come on!

　　After work, the lights are already on outside. Because the team suggested that the medical staff should not eat directly in the canteen after work, fearing that it would be too late to eat after cleaning, I chose a self-heating hot pot and some fruits from the "energy station" and changed the dinner!

In the Tang Dynasty, the activities of enjoying lanterns became more prosperous. Lights were hung everywhere in the palace and on the streets, and tall lantern wheels, lantern buildings and lantern trees were also built. Lu Zhaolin, a great poet in the Tang Dynasty, once described the grand occasion of burning lanterns on Lantern Festival in "Watching Lights on Fifteen Nights", saying that "the stars in the Han Dynasty are falling, and the buildings are like the moon hanging."

　　In the Song Dynasty, more attention was paid to the Lantern Festival, and the lantern viewing activities were more lively. The lantern viewing activities lasted for five days and the styles of lanterns were more abundant. In the Ming Dynasty, the lantern festival will last for 10 days, which is the longest lantern festival in China. Although there were only three days of lantern viewing in Qing Dynasty, the lantern viewing activities were large in scale and unprecedented in pomp. Besides burning lanterns, fireworks were also put on to entertain.

In the Southern Song Dynasty, the capital Lin ‘an made riddles every Lantern Festival, and there were many people guessing riddles. At the beginning, it was a busybody who wrote riddles on paper and pasted them on colorful lanterns for people to guess. Because riddles are enlightening and interesting, they are welcomed by all walks of life in the process of spreading.

Filled with bean paste, sugar, hawthorn, all kinds of fruit materials, etc., it can be cooked, fried, steamed and fried when eating. At first, people called this kind of food "Floating Yuanzi", and later they called it "Tangtuan" or "Tangyuan". These names "Reunion" have similar sounds, meaning reunion, which symbolizes the reunion of the whole family, harmony and happiness, and people also miss their parting relatives and place their good wishes on their future life.

　　In some places, the Lantern Festival also has the custom of "walking all kinds of diseases", also known as "roasting all kinds of diseases" and "dispersing all kinds of diseases". Most of the participants are women. They walk together or walk by the wall, or cross the bridge and walk in the suburbs, in order to drive away diseases and eliminate disasters.

　　With the passage of time, there are more and more activities in the Lantern Festival, and many local festivals have added traditional folk performances such as playing dragon lanterns, playing lions, walking on stilts, rowing dry boats and dancing yangko, and playing Taiping drums. This traditional festival, which has been passed down for more than 2,000 years, is not only popular on both sides of the Taiwan Strait, but also celebrated year after year in areas inhabited by overseas Chinese.
