recent days

A 20-year-old man appeared in Hangzhou.

Symptoms such as fever and sore throat.

After a week of fever

The neck is swollen, too

I came to the hospital and found that

His B-ultrasound showed enlarged cervical lymph nodes.

And liver function is abnormal.

After further examination

The cause was clarified.

↓↓↓

The results showed that EB virus related indicators were positive.

Diagnosed as "acute EB virus infection"

Commonly known as "kissing disease"

The main route of transmission is saliva transmission

More than 90% of adults carry EB virus.

Jin Jie, director of the Department of Infectious Diseases of the First People’s Hospital of Hangzhou, explained that more than 90% of adults carry EB virus, and most adults have been implicitly infected with kissing disease. However, due to its strong self-resistance and complete immune response mechanism in the body, adults infected with kissing disease may not have any abnormal symptoms.

Although there may be no symptoms, the EB virus carried by adults is extremely easy to infect children and other people with weak body resistance. That is to say, when a person carries EB virus, although he has no symptoms and the examination shows well, the virus is still contagious.

Similar to the symptoms of a cold, how to distinguish it?

The doctor said that early identification and symptomatic treatment are very important for the treatment of kissing disease. The early symptoms of EB virus infection are similar to those of influenza, with fever, stuffy nose and sore throat, so it is easy to be confused. The most typical symptom of kissing disease is repeated fever, which lasts for no less than 5 ~ 7 days, while fever caused by common cold or flu generally improves within 3 ~ 5 days.

Therefore, as long as you find that the fever persists, especially for children and people with low immunity, don’t carry it hard. You should go to the hospital in time to avoid delaying the further development of the disease.

How to prevent "kissing disease"

child

In addition to reducing kissing children, adults are advised to avoid mouth-to-mouth feeding and not to give children food chewed by adults. Children use separate tableware and cups, and prepare public chopsticks on the dining table.

Patients in acute phase should be isolated from respiratory tract. Keeping your hands clean is an effective way to stop the spread of the virus. Especially after touching public facilities, be sure to clean your hands thoroughly with running water and soap. Wearing a mask can reduce the risk of virus transmission through the respiratory tract during crowded or viral epidemics.

A nutritious and balanced diet helps to strengthen the immune system. Eat more foods rich in vitamins and minerals, such as fresh fruits and vegetables and whole grains. At the same time, moderate physical activity can enhance the body’s resistance.

Avoid close physical contact with EB virus-infected people, especially in the season of high virus incidence. Safe sex is also one of the important preventive measures, because EB virus may spread through body fluids such as saliva.

Through blood test, EB virus infection can be found early and intervention measures can be taken in time. Especially for groups with weak immune system, such as the elderly, consult professional doctors in time.

"What I care about most is the most precious thing left by Chinese civilization through vicissitudes. Our culture continues to flow and then pass on, and these treasures left behind must be taken care of and cherished by all means. " Not long ago, when visiting the Central General Hall of China National Edition Pavilion, General Secretary of the Supreme Leader said earnestly.

Treasures are collected in museums, written in ancient books and displayed on the vast land. For these cultural relics and cultural heritages bearing the genes and blood of the Chinese nation, the Supreme Leader General Secretary cherishes them.

From the inheritance of cultural heritage to the protection of natural heritage, from strengthening the protection and utilization of material cultural heritage to stimulating the innovation vitality of intangible cultural heritage … … The general secretary cares about and promotes the protection of cultural and natural heritage from the strategic height of retaining cultural roots and keeping the soul of the nation.

June 10th this year is Cultural and Natural Heritage Day. Let’s follow the supreme leader’s "cultural footprint" and realize his earnest expectations for inheriting and protecting historical and cultural heritage and natural heritage and promoting the rejuvenation of Chinese civilization.

Pay attention to a mountain — — Message "This article should be done well"

The purpose of applying for the World Heritage is to better protect and utilize it. The General Secretary of the Supreme Leader has given important instructions to "carefully protect the cultural heritage left by our ancestors so that the historical context can be better passed down".

On the evening of December 1, 1999, Wuyishan City, Fujian Province was in a festive and lively atmosphere.

At the 23rd World Heritage Conference held in Morocco, Wuyishan was listed in the World Heritage List, which became the fourth double heritage of world culture and nature in China, and also achieved a breakthrough of zero world heritage in Fujian Province.

The next day, the supreme leader of the then acting governor sent a letter to the Wuyishan Municipal Party Committee and Municipal Government, congratulating the success of the application.

“‘ World cultural and natural heritage ’ This intangible value is immeasurable, and it has far-reaching significance for the future development of Wuyishan tourism, and it will soon bring a tourism boom. " Half a month later, the supreme leader went to Nanping for investigation, spoke highly of Wuyishan’s "Double World Heritage" and encouraged "this article should be done well".

At the end of 1990s, Wuyishan, which is "a wonder in the southeast", began to declare the World Heritage. At that time, the deputy secretary of the provincial party Committee and the supreme leader paid close attention to the progress of the declaration and actively coordinated and promoted the relevant work.

△ On March 22, 2021, General Secretary of the Supreme Leader was in Zhu Xi Garden, Wuyishan, Nanping, Fujian, to learn about Zhu Xi’s life and neo-Confucianism.

At that time, many people thought that Wuyi Mountain’s application for the World Heritage might be to obtain natural heritage, and it might not be able to get the cultural heritage in the vast cultural ocean of the world.

The site of Seoul, a city village with a heavy history, is an important part of the application for the World Heritage. It can be said that it is precisely because of the ancient Seoul that Wuyishan’s "Double World Heritage" was created. In the process of applying for the World Heritage, the Fujian Provincial Department of Culture began to build the Fujian-Vietnam Wangcheng Museum to undertake the protection and management of the Seoul ruins in Chengcun. The Fujian Provincial Party Committee Organizational Committee, headed by the Supreme Leader, actively supported it.

△ Minyue Wangcheng Museum. The site of Seoul has a history of more than 2,200 years, and it is the largest and best-preserved city site of the Han Dynasty found in southern China so far.

With the concerted efforts of all parties concerned, the site of Chengcun Seoul passed the inspection and was praised as "Pompeii City of China" by the UNESCO World Heritage Delegation.

World heritage should not only be used, but also protected. The supreme leader is very concerned about the protection of Wuyi Mountain’s "Double World Heritage". In December, 2001, he made a special trip to inspect the ruins of Seoul, Wuyishan City Village, and told him that "ancient Seoul is a cultural national treasure, which should be carefully studied and rationally developed" and that "development should follow scientific laws and form a research trend of sustainable development".

Based on this, the archaeological excavation of Seoul site has been continuously increased. In December 2013, Chengcun Seoul Archaeological Site Park was included in the second batch of national archaeological site parks. At the end of last year, the park was successfully selected into the list of national archaeological sites parks.

Listen to an epic poem — — Encourage to "carry forward the excellent traditional culture of all ethnic groups"

Manas, handed down from generation to generation, is one of the three major epics of China’s ethnic minorities, which are equally famous as Gesar and Jianger, and it is a classic to praise heroes.

General Secretary of the Supreme Leader mentioned this heroic epic many times. During his trip to Xinjiang in July 2022, the Supreme Leader watched the rap show of Manas in the Museum of Xinjiang Uygur Autonomous Region.

△ On July 13th, 2022, General Secretary of the Supreme Leader was in the Museum of Xinjiang Uygur Autonomous Region, together with the inheritor of the intangible cultural heritage of Manas.

"How long can you sing?" The general secretary asked with a smile.

"I can’t finish singing all day and all night." Jiang Nur, the inheritor and herder of Manas, replied.

"I can only sing for 60 minutes." The 14-year-old apprentice who had been studying art since he was 3 years old was ashamed.

"It’s not easy!" The general secretary said to the teenagers, "The younger generation should be well trained, and the protection and inheritance of intangible cultural heritage should be better strengthened to carry forward the excellent traditional culture of all ethnic groups."

"Have you encountered any difficulties?"

"I want the whole world to know about Manas." Jiang Nur’s eyes are full of longing.

"Is to spread to the world. They are not only ethnic minorities, but also precious wealth in the treasure house of Chinese culture. Chinese culture should better communicate and learn from other cultures. The CPC Central Committee attaches importance to and supports this work. " The general secretary said affirmatively after listening.

Because China has been making continuous efforts to protect intangible cultural heritage, Manas, which once faced the crisis of loss, has revived. In recent years, Manas has not only been translated into many languages and widely published, but also operas based on it have been staged many times. This heroic epic has entered a broader cultural field.

When visiting ethnic minority areas, the Supreme Leader General Secretary often pays attention to the protection and inheritance of ethnic minority cultures — — Learn about the texture of Tibetan carpets in Qinghai, ring Wa wooden drums in Yunnan, and attend a blessing ceremony in Inner Mongolia.

△ On January 27th, 2014, at the winter "Five Livestock Blessing" ceremony in Nadam, Baoligen Sumu (township), Xilinhot City, Inner Mongolia, General Secretary of the Supreme Leader dipped his ring finger in fresh milk in a silver bowl and played it three times in accordance with Mongolian customs, wishing good weather, prosperity of five animals and happiness and well-being of the people in the coming year.

General Secretary of the Supreme Leader stressed: "Chinese civilization is profound and has a long history, and it is formed by the confluence of excellent cultures of all ethnic groups."

It is the fertile soil of multi-ethnic culture rooted in harmony but different that has contributed to the everlasting Chinese culture. This is the important wisdom that Chinese civilization has become the only civilization in the world that has not been interrupted and has developed to this day.

Investigating a Temple — — Admonish "to strengthen cultural self-confidence"

"A father and son three-word guest, four people through the ages." In Meishan city, the streets and lanes are full of profound cultural atmosphere because of the three Soviet fathers and sons.

On June 8 last year, General Secretary of the Supreme Leader who visited Sichuan walked into Sansu Temple.

Front hall, dining hall, Qixian Hall, Laifengxuan … … The general secretary walked all the way to think.

△ Sansu Temple

"A drop of water can see the sun, and a Sansu Temple can see the profoundness of our Chinese culture. We say that we should strengthen our cultural self-confidence, and China has ‘ Sansu ’ This is an important example. " The general secretary said with emotion.

From cultural self-confidence to road self-confidence, he said: "The Chinese nation has a long history of civilization of more than 5,000 years, and we are leading the people along the road of Socialism with Chinese characteristics. We must be good at learning the ideas and thinking of governing the country from the excellent traditional Chinese culture, and learn from all the outstanding achievements of civilization in the world. We must not be closed and rigid, and we must not take foreign things as the standard. "

The road of Socialism with Chinese characteristics came out under the guidance of Marxism, and it also came out from the history of Chinese civilization for more than 5,000 years.

At the recent symposium on cultural inheritance and development, the General Secretary of the Supreme Leader clearly pointed out: "Why is our socialism different? Why can it be full of vitality? The key lies in the characteristics of China, and the key to the characteristics of China lies in ‘ Two combinations ’ 。” “‘ The second combination ’ It is another ideological emancipation that allows us to make full use of the valuable resources of Chinese excellent traditional culture in a broader cultural space and explore future-oriented theoretical and institutional innovations. "

△ Interior of "Wenhan Pavilion" in the Central General Pavilion of China National Edition Pavilion. On the dome of the starry sky is an astronomical map of stone carvings in the Song Dynasty, which conveys the meaning of "Wenhan Pavilion": Chinese civilization is as vast and bright as the starry sky.

Chinese civilization endows Chinese-style modernization with profound connotation, and Chinese-style modernization endows Chinese civilization with modern strength.

In the decade of the new era, with the attention and guidance of the Supreme Leader General Secretary, China’s cultural and natural heritage protection has been developing continuously — —

China has 56 world heritages, ranking second in the world in total.

Up to now, China has identified more than 100,000 non-legacy representative projects at all levels. Forty-three projects are listed on the UNESCO Intangible Heritage List, ranking first in the world.

By the end of 2021, more than 2.7 million copies of ancient books had been registered, more than 3.85 million pieces of ancient books had been restored, and 17 national and industrial standards for the protection of ancient books had been formulated and promulgated.

At present, China has announced 140 national historical and cultural cities and 6,819 traditional villages in China; There are more than 36,000 immovable revolutionary cultural relics in China, and more than 1 million movable revolutionary cultural relics in state-owned collections.

Only by not forgetting the original can we create the future.

As the general secretary said: "The best inheritance of history is to create a new history; The greatest respect for human civilization is to create a new form of human civilization. "

On the new journey, the sons and daughters of China will strengthen their cultural self-confidence, take on the mission and work hard to create a new culture belonging to our time and build a modern civilization of the Chinese nation.

1905 movie network news The epic film of national mythology is being well received. The director, starring actor, production designer Zhao Shouyi and voice guide zhaonan to Jinan Station, a national tour ceremony, to share behind-the-scenes stories about the relationship between Yin Shou and Master Wen, the props of mysterious birds at the enthronement ceremony, the voices of Lei Zhenzi, a dragon and a tiger and a glutton. The film is directed by Wu Ershan, starring ChristianRandPhillips, Chen Muchi, Na Ran, Wu Yafan,,,, Huang Xiyan, and Chinese’s own mythical epic, which should not be missed.

ChristianRandPhillips revealed the relationship between Yin Shou and Wen Taishi.

Young actors put their hearts and minds into performances.

The film "Feng Shen Part I" was directed by Wu Ershan, starring ChristianRandPhillips, Chen Muchi, Na Ran, Wu Yafan, Huang Xiyan and Shan Jingyao. production designer Zhao Shouyi and voice were used to guide zhaonan to communicate and interact with the audience. When each actor introduced himself, the audience gave warm applause and even shouted out the lines of the corresponding roles, which not only touched the actors, but also touched the director Wu Ershan: "There are many roles and stories in" Feng Shen I ",and each actor can impress everyone in a small performance space, especially the young actors are acting for the first time. I am proud of them."

In the ending egg of "Wen Taishi returns to the DPRK", new characters such as Wen Taishi, Deng Chanyu, and Magic Four Generals appeared, which made people shine. Many viewers were also curious about their relationship with Shang Wang Yinshou. ChristianRandPhillips said with a smile that "Wen Taishi will come back soon to avenge me". He introduced that Master Wen is the elder of Yin Shou and the only person he really fears, Deng.fairJade was brought back to Chaoge by Master Wen. Yin Shou had never seen it before, but he would make good use of these two people. Chen Muchi received a T-shirt with the second creation of "Master Wen returns to the DPRK" printed on the back, and said with a smile: "Master Wen should be at the noon gate of Chaoge City soon, and then he will slowly find that the two gluttons at the door are gone, Priestess of Death Bigan is gone, the Queen Jiang is gone, and the prince is killed, so as to see the truth of all this", which also makes the audience look forward to the plot of the second part.

Many viewers think that da ji, played by Na Ran, is very innovative in character setting and performance style, presenting a pure da ji as an animal. Na Ran was very happy to see the audience’s recognition of his acting skills, and said that all the motives of da ji’s actions were to repay the debt and survive. Director Wu Ershan also pointed out that in the movie, Queen Jiang, Yin Jiao and Bigan tried to kill da ji, the fox demon. She was only in a state of self-protection, and the core of evil was always Yin Shou, in fact, Yin Shou wanted to get rid of those who hindered his desires and ambitions.

Although there are not many scenes in the film, Su Quanxiao is an important scene that embodies proton setting and Yin Shou’s character. Shan Jingyao made a lot of preparations for this, including writing a particularly long biography of Su Quanxiao, and because he likes painting, he painted Su Quanxiao’s various situations and feelings for his family when he sang songs. For example, Su Quanxiao loathed his sister da ji and hated his father Su Hu’s decision to send him away, but he also knew that his mother was very much looking forward to his return home. By establishing these relationships, Shan Jingyao made himself believe in this character more and more. And his play also brought a lot of inspiration to Huang Xiyan. Huang Xiyan said frankly that it was more difficult to ponder after getting the script at first, because Jiang Wenhuan’s state of mind was different at each stage, and he continued to make progress. Later, he saw Su Quanxiao, played by Shan Jingyao, commit suicide on the set, and thought of the precious memories of a group of brothers getting along in the past few months. At that moment, he combined himself with proton Jiang Wenhuan through emotional substitution. Young actors put their hearts and minds into their performances, which undoubtedly touched countless audiences.

The props of "Xuanniao Shengshang" are from Weifang, Shandong Province.

Voice-guided analysis of biological voice of digital characters

The audience at Jinan Station, a national tour ceremony, loved "The First Part of Gods" and gave them good comments in succession. "A well-made masterpiece, with well-chosen actors, is full of stamina after reading it." "Sincerity is always the most touching thing, and I can feel the intention of the whole creative team. From now on, I am the tap water of Gods." "The second brush effect is even more shocking, and the crew can be felt from the drama, actors and art design.

The first part of "Feng Shen" brought many visual wonders to the audience, not only the special effects scenes such as hordes of troops and gluttony, but also the sacrificial scenes such as "Xuanniao Shengshang" in the enthronement ceremony, which was equally refreshing. Wu Ershan, the director, told the audience that the Xuanniao props were specially customized by the non-genetic person who found the display prop production designer Ji Zhaolong to tie a kite in Weifang, Shandong Province. Because the Xuanniao props were large, light and beautiful, the traditional craft of tying kites was adopted to solve the weight problem, and the main structure was tied with bamboo, and then covered with cotton cloth, so that the actors could hold and dance, presenting a mysterious ceremony in the Shang Dynasty.

As a mythical epic film, the first part of "Feng Shen" has thousands of Ma Benteng, thousands of arrows, thousands of people worshipping, and bloody wars and dances, which make the audience feel the immersive auditory impact. When talking about the challenge of sound production, zhaonan, the director of sound, said with emotion that this is a huge workload of sound. I still remember that director Wu Ershan said for the first time in the recording studio that "you need to build a mythical and epic world with sound". Zhaonan, the voice guide, introduced the voices of Lei Zhenzi, Dragon and Tiger and Gluttony to the audience. When Lei Zhenzi spread his wings, the wind thundered, and the audience could hear the thunder rolling, while he held Ji Changfei to Xiqiao, and the voice was mixed with the voice recorded by the dynamic capture actor Pengyi Han, reflecting human emotions. The dragon-bearded tiger is a symbol of justice, and its call mainly uses sperm whales, and it combines the flowing, curved and rhythmic timbre of other whales. The two gluttons in the movie were originally clay sculptures, so they used the twisted sounds of wood, stones and grass sticks to represent their cries. When the gluttonous man jumped off the Yellow River with Ji Fa, the voice guide zhaonan made a contrast between the gluttonous cry and the roar of the Yellow River, hoping to make the audience feel more powerful with the surging momentum of the Yellow River, the mother river of the Chinese nation. I believe that everyone who walks into the cinema can enjoy a thrilling audio-visual feast.

The film "The First Part of Gods" is directed by Wu Ershan and starred by ChristianRandPhillips, Li Xuejian, Bo Huang, Yu Shi, Chen Muchi, Na Ran, this sand, Wu Yafan, Xia Yu, Yolanda, Wang Luoyong, Hou Wenyuan, Huang Xiyan, Li Yunrui, Yang Le and Chen Kun. The film is being shown.

Work together to promote modernization and build a community of destiny.

— — Keynote speech at the opening ceremony of the Beijing Summit of the Forum on China-Africa Cooperation

(Beijing, September 5, 2024)

Chairman People’s Republic of China (PRC), Supreme Leader

　　Dear President Faye,

　　Dear President Ghazwani, the rotating chairman of the African Union,

　　Dear Heads of State, Government and Delegation,

　　Chun Hua Qiu Shi, old things are rich. In this harvest season, I am very happy to meet all the old and new friends in Beijing to discuss the friendly cooperation between China and Africa in the new era. First of all, on behalf of the government of China and the people of China, I would like to extend a warm welcome to all of you!

　　China-Africa friendship crosses time and space, mountains and seas, and is passed down from generation to generation. The establishment of the Forum on China-Africa Cooperation in 2000 is an important milestone in the history of China-Africa relations. Over the past 24 years, especially since the new era, China has been working hand in hand with African brothers and sisters in the true and sincere concept. We are shoulder to shoulder and hand in hand in the century-old changes in the world, firmly defending each other’s legitimate rights and interests; In the tide of economic globalization, we have strengthened our bones and muscles, and achieved fruitful results to benefit hundreds of millions of people in Central Africa; In the face of great disasters and epidemics, we worked hard together and wrote a touching story of China-Africa friendship; We have always understood each other and supported each other, setting a new model of international relations.

　　After nearly 70 years of hard work, China-Africa relations are at their best in history. Facing the future, I propose that the bilateral relations between China and all countries that have diplomatic relations with Africa be upgraded to the level of strategic relations, and the overall positioning of China-Africa relations be upgraded to an all-weather community of China-Africa destiny in the new era!

　　Dear friends and distinguished guests!

　　Realizing modernization is an inalienable right of all countries in the world. The process of western modernization has brought great suffering to developing countries. After the Second World War, the third world countries, represented by China and Africa, achieved independence and development one after another, and constantly corrected historical injustices in the process of modernization. People’s Republic of China (PRC) is about to celebrate its 75th birthday, and is unswervingly promoting the construction of a strong country and the great cause of national rejuvenation with Chinese modernization. Africa is also experiencing a new awakening and making steady progress towards the modernization goal described in the African Union’s Agenda 2063. The dream of China and Africa pursuing modernization together will surely set off a global modernization upsurge in the South and write a new chapter in building a community of human destiny.

　　— — We should work together to promote fair and reasonable modernization. To promote national modernization, we should not only follow the general law of modernization, but also conform to the reality of our country. China is willing to strengthen exchanges of experience in governing the country with Africa, support countries to explore modernization paths suited to their national conditions, and ensure equal rights and opportunities for all countries.

　　— — We must work together to promote open and win-win modernization. Mutually beneficial cooperation is in the long-term and fundamental interests of all countries, sunshine avenue. China is willing to deepen cooperation with Africa in the fields of industry, agriculture, infrastructure, trade and investment, set a benchmark for building the "Belt and Road" with high quality, and jointly create a model for implementing global development initiatives.

China is willing to actively cooperate with Africa in personnel training, poverty alleviation, employment and other fields to enhance people’s sense of gain, happiness and security in the process of modernization, and jointly promote modernization to benefit all people.

　　— — We must work together to promote the modernization of pluralism and tolerance. Realizing the coordinated development of material civilization and spiritual civilization is the lofty pursuit of modernization. China is willing to have close cultural exchanges with Africa, advocate mutual respect and inclusive coexistence of different civilizations in the process of modernization, and jointly promote the global civilization initiative to bear more fruits.

　　— — We should work together to promote eco-friendly modernization. Green development is a distinctive symbol of modernization in the new era. China is willing to help Africa build a "green growth engine", narrow the gap in energy accessibility, adhere to the principle of common but differentiated responsibilities, and jointly promote global green and low-carbon transformation.

　　— — We should work together to promote the modernization of peace and security. Modernization is inseparable from a peaceful and stable development environment. China is willing to help Africa enhance its ability to independently maintain peace and stability, promote global security initiatives to take the lead in Africa, promote the benign interaction between high-quality development and high-level security, and jointly safeguard world peace and stability.

　　Dear friends and distinguished guests!

　　China and Africa account for one third of the world’s total population. Without the modernization of Central Africa, there would be no modernization of the world.

　　Second, trade prosperity partnership action. China is willing to take the initiative to unilaterally open its market, and has decided to give 100% tariff-free treatment to all the least developed countries that have established diplomatic relations with China, including 33 African countries, to become the first large developing country and the world’s major economy to implement this initiative, and to promote China’s big market as a great opportunity for Africa. Expand access to agricultural products in Africa, deepen cooperation in e-commerce and other fields, and implement the "China-Africa Quality Improvement Plan".

　　Dear friends and distinguished guests!

　　In July this year, the Third Plenary Session of the 20th Central Committee of the Communist Party of China (CPC) was successfully held, which made systematic arrangements for further comprehensively deepening reform and promoting Chinese modernization. This will further profoundly change China, and will certainly provide new opportunities and inject new kinetic energy into African countries and China and Africa’s dream of pursuing modernization together.

　　There is an African proverb that "people who go the same way are true friends". No one can be left behind on the road to modernization, and no country can fall behind. Let us unite the majestic strength of more than 2.8 billion Chinese and African people, walk hand in hand on the journey of modernization, help the modernization of the global South with the modernization of China and Africa, draw a brand-new picture in the history of human development, and jointly push the world towards a bright future of peace, security, prosperity and progress!

　　Thank you.

　　In recent years, with the rapid development of short videos, the network charm index of cities such as Chongqing, Xi ‘an, Chengdu and Hangzhou has soared. Chongqing’s 8D magic interchange, Xi ‘an’s tumbler performance, Xiamen’s seaview subway … … These scenes with their own traffic attract a large number of tourists to spread and share on the Internet. Experts pointed out that behind the hot popularity, how to turn the flow economy into an incremental economy and shape the real urban competitiveness is an important issue for online celebrity cities.

　　"online celebrity punching place" is hot

　　Xiao Zhao, a Beijing girl who is engaged in the clothing industry, is keen on traveling. She and several friends like to "walk away". Before going to a place, she didn’t do much travel strategy. Often, when she arrived at her destination, she went to Tik Tok and other short video platforms to search for popular videos related to the tourist destination, and then happily "punched in" together, or enjoyed the unique natural and cultural landscape, or felt the wonderful historical and cultural customs, or tasted the mouth-watering local specialties. "Taking photos, taking short videos, making friends circle and trembling sound are must-do in travel."

　　In recent years, the rise of social networks has changed many people’s travel habits. Whether it’s a traditional scenic spot or a new landmark, once it has the label of "online celebrity", it will attract tourists to take photos or take videos to "punch in".

　　Recently, People’s Daily People’s Cultural Tourism Research Institute and others published the TOP20 Value Recommendation List of "online celebrity Punching Places" for National Cultural Tourism, recommending high-quality tourism resources from three dimensions: attention, reputation and expert evaluation. The selected 20 "online celebrity Punching Places" have the following characteristics: First, they must have aesthetic feeling to meet the needs of tourists for photography, such as Sakura Avenue, Chaka Salt Lake and Dongji Island; Secondly, it can highlight personality and meet the needs of tourists to show their taste, such as THE BRIDGE covered bridge in Chengdu; In addition, it can provide different tour experiences to satisfy tourists’ sense of freshness and participation, such as Xiamen Seaview Subway and Xi ‘an Yongxingfang "Bowling Wine".

　　“‘ Online celebrity punching place ’ The popularity is largely due to the new media communication methods. " Xu Fengwen, chief planner of the Cultural Tourism Center of Tianjin University Architectural Design and Planning Research Institute, said that people’s demand for the participation and dissemination of online celebrity scenes has changed from the traditional view of the city to the experience of specific city scenes.

　　Nowadays, more and more tourists release short videos to exchange travel strategies and experiences. Insiders pointed out that short video has become an important communication and expression tool, which has mobilized the enthusiasm of tourists to record and discover the charm of the city. The reason is, first of all, because short travel videos are more intuitive, richer, story-telling, entertaining and more impressive to others. In addition, in the short videos taken by tourists, scenic spots and food are often more grounded and can appreciate a city at close range. In addition, friends like to go to the "punch card place", and they also go to make a card and connect with each other in a brand-new way, which is also a new form of social interaction.

　　"Lens" makes online celebrity city.

　　Today, it has become the norm that a "online celebrity punching place" is a city with fire. The White Paper on Beautiful City Index: the Relationship between Short Video and Urban Prosperity published by China Urban Planning and Design Institute shows that the content related to urban travel on short video can not only drain online, but also drive offline "planting grass". More than 80% of Tik Tok users said that they would "punch in" because they like short videos of specific cities, scenic spots and business districts.

　　Under the trend of new media communication, the "punching place in online celebrity", which is favored by young consumers, has great potential in enhancing the popularity of cultural tourism brands. To this end, various localities have launched relevant measures to activate and promote cultural tourism resources. For example, Beijing recently launched the "First Beijing Net Red Punch Site Selection" activity, where the public can participate in recommendation and voting through the Internet to help their own Beijing-style "online celebrity"; Kunming launched the promotion activity of "punching places for cultural tourism" to encourage citizens and tourists to explore new landmarks in the city; Chongqing held the promotion activity of "Sun Culture Sun Scenery" to show the "face value" and "temperament" of "City of Mountains and Waters" with the help of social media platform.

　　Some cities have been re-recognized by young people through emerging media platforms. Among them, short videos have become an important scene to create new business cards for cities, opening up a new possibility for "lens" to create online celebrity cities. For example, since July, 2019, Xi ‘an Datang City Scenic Area has designed two street performance art performances of tumblers according to Xi ‘an city mascots "Tang Bao" and "Tangniu", and soon the performance of "Real Tumbler" Picachen became popular. On Tik Tok, the video under the topic of "Miss Tumbler" has been played 2.77 billion times. In this regard, Nan Chuxin, deputy director of the china society of economic reform Internet and New Economy Professional Committee, said that compared with traditional city landmarks, such tourist scenes are more modern, approachable and cultural, and are favored by the younger generation. This kind of city "punching in" behavior based on characteristic IP not only brings traffic explosion, activates the local tourism economy, but also personifies and rejuvenates the image of scenic spots, which injects new kinetic energy into the cultural tourism industry.

　　However, in reality, there are also some areas that blindly follow the trend. For example, regardless of their own personality and characteristics, they copy and introduce "punch-in" elements such as tumbler performance, glass plank road, sky mirror and light show. "Blindly chasing the real-time effect of the network, being out of position and being surprised, we must pay attention to prevention! In particular, it is necessary to prevent rushing headlong into it, copying it, and mismatching the name. " Jin Yuanpu, director of the Institute of Cultural and Creative Industries of Renmin University of China, said in an interview that every city has its own genes, and it is necessary to shape its unique image and temperament.

　　Fully "realize" the traffic

　　A few days ago, the "Top 100 online celebrity Cities in China Tide Economy 2020" published by a certain platform measured the "online celebrity Degree" of a city from five dimensions: network popularity index, live broadcast index, tide life index, industrial development index and impression index. The top 10 cities in online celebrity are: Beijing, Shanghai, Guangzhou, Shenzhen, Hangzhou, Chengdu, Xi ‘an, Changsha, Nanjing and Chongqing. Experts pointed out that the high popularity of online celebrity city is actually the result of a series of factors, such as urban cultural heritage, economic strength, population size and even scientific and technological progress.

　　"online celebrity city is not only a city that is popular on the Internet. A online celebrity city must form a high-quality development model if it wants to be red for a long time and keep its traffic. " The insiders believe that in the era of "attention economy", how to transform online traffic into the core competitiveness of the city, and finally attract the influx of people and form an industrial agglomeration effect is the ultimate goal of the city to create a "online celebrity label".

　　According to Huang Hancheng, the chief researcher of Zhigu Trend, only when people gather through Internet traffic, such as tourists who spend money or talents who come to settle down, can online celebrity be regarded as a city. The "online celebrity Effect" can’t be underestimated, for example, in recent years, Chongqing’s tourism fever is among the highest, and in 2019 alone, 657 million people visited Chongqing, achieving a total tourism income of 573.4 billion yuan.

　　In this regard, Jin Yuanpu said that in order to turn online traffic into real dividends, supporting facilities and public services should be in place, and more detailed work should be done in all aspects of urban development, especially in the upgrading of tourism. Through the system construction of new technologies, new management and new operations, tourists’ sense of experience, participation and integration will be continuously enhanced.

　Every sacrifice is immortal ―― On Urumqi’s "1? 2 "Fire Fighting Hero"

　　　 This is the banner of "Heroes Go All the Way" by Urumqi citizens (photo taken on January 7). On January 7, in Urumqi, Xinjiang, "1? 2 "The memorial service for three fire officers and soldiers who died in the fire in Dehui International Plaza was held in Urumqi, and the relatives of three martyrs and nearly 10,000 people from all walks of life in Xinjiang attended the memorial service. Xinhua News Agency reporter Zhao Geshe　
　　　

　　　 Xinhuanet Urumqi, January 8 th (Reporter Yan Huang, Gao Fan)At the beginning of the new year in 2008, a raging fire that raged for more than 60 hours swept away the New Year atmosphere in the north and south of Tianshan Mountain. In the process of putting out this fire, three names will live forever in the fire.

　　　 "Assembly" blew and rushed into the sea of fire.

　　　 At 20 o’clock on the evening of January 2, an emergency fire alarm interrupted the New Year meeting of the First Squadron of Urumqi Fire Brigade. The 33 soldiers of the whole team set off in an instant and rushed to the scene of the fire.

　　　 That night, Zhu Xiaolei, the deputy squadron leader who was on vacation at home, learned of the fire, bid farewell to his parents at home and went straight to the fire. The on-site command center quickly dispatched Zhu Xiaolei, Zhang Yu and Gao Feng to form a rescue commando. At the last moment of rushing into the fire, Zhu Xiaolei did not forget to call his father: "Dad, I signed up for the death squad … I rushed in!" "

　　　 At 22: 20 that night, three people successfully rescued three trapped people from the building. When informed by the headquarters that there were still trapped people in the building, the three men rushed into the building completely covered by black smoke, high temperature and toxic gas for the fourth time.

　　　 The visibility in the building was less than 50 cm, and the three people lost their way. The on-site commander immediately organized rescue after receiving Zhu Xiaolei’s distress signal, but when his comrades found Zhu Xiaolei and Zhang Yu on the sixth floor, they were already unconscious on the ground.

　　　 "Zhu Xiaolei was panting at the time, but he could only exhale and could not inhale. I slapped Zhang Yu’s face to stimulate him to regain consciousness, but he never responded. " Wang Li, a rescuer, said with a trembling voice.

　　　 After Zhu Xiaolei and Zhang Yu were carried out of the building, the passage of the building was completely blocked by fireworks in an instant. In order to avoid more casualties, the on-site command center decided to stop the search and rescue peak.

　　　 When Zhu Xiaolei and Zhang Yu were sent to the ambulance, the comrades wiped their tears with dark hands and put their heads on the window, because they knew in their hearts that this look was probably a farewell.

　　　 On the morning of the 4th, Xinjiang Fire Corps announced that Zhu Xiaolei, the deputy squadron leader of Special Service No.1 Squadron, and Zhang Yu, the trainee platoon leader, were all rescued by the medical department, and died heroically because of smoke poisoning. Gao Feng’s body was also found on the east side of the 6th floor at 14: 00 on the 4th.

　　　 The "post-80s" heroes moved tens of thousands of people in border towns to mourn spontaneously.

　　　 Zhu Xiaolei, Zhang Yu and Gao Feng, three fire-fighting heroes, were all born in the 1980s. Their feats shook the border town in winter. In the past few days, tens of thousands of people of all ethnic groups have spontaneously mourned the heroes of fire fighting.

　　　　On the morning of January 4, thousands of Urumqi citizens spontaneously came to the mourning hall set up in the Second Squadron of the Special Service of the Municipal Fire Brigade to pay their respects at "1? 3 heroes who died in the fire. The mourning hall has been filled with wreaths, and civil servants, taxi drivers, personnel from enterprises and institutions, and affected merchants from Dehui International Plaza have come from Urumqi and nearby cities to mourn the firefighting hero.

　　　 On the morning of the 7th, the cold wind blew in Urumqi, and painful sorrows resounded through the border town. Tens of thousands of people from all ethnic groups gathered in Yanerwo funeral home in Urumqi to bid farewell to the heroes. The main streets of Urumqi, such as Guangming Road and Xinhua Road, are full of sadness and music. Hundreds of cars are wearing white flowers and carrying wreaths and slowly heading for Yanerwo funeral home in the southern suburbs. On both sides of the street, the mourners watched in tears.

　　　 On the square outside Yan ‘erwo Funeral Parlour, the warning lights of fire engines kept flashing, and private cars and taxis of all sizes turned on their lights. Tens of thousands of people stood neatly in the open space of the square, holding up the words "Heroes have a good trip!" "The loveliest people are you!" Waiting for the banner of the eulogy.

　　　 Alamuti, an old man who runs a baking cake shop, wiped his tears and said, "I saw the hearse pass in front of my shop, so I closed the door and rode over." If nothing else, I just want to see the three heroes’ Balangzi’. " After donating 100 yuan to the families of the martyrs, a poorly dressed car mechanic said, "I don’t know what to say. When the heroes are gone, I just want to donate some money to their families to express my heart."

　　　 In Baidu Post Bar, netizens initiated "Let the hero’s spirit be with Tianshan Mountain, and let the hero’s spirit live with the desert forever!" The network martyr memorial service. The spirit of martyrs is spreading, and the love of the people is passing on. People from all walks of life not only spontaneously mourn the martyrs who died, but also donate money and materials to the families of martyrs through various channels. At the memorial service on the 4th and 7th, nearly 10,000 people, including the affected merchants in Dehui International Plaza, donated money to the families of martyrs in various ways.

　　　 Hero, did not leave.

　　　 On the morning of January 3, the fire in Dehui International Plaza in Urumqi was still spreading. Although after more than 10 hours of fighting, the fire in the wholesale market of Lutehui International Plaza in Qiantang River in Urumqi is still spreading, and some floors of Dehui Hotel connected to it have also started to catch fire, and all the people in the hotel have been evacuated safely. At 20 o’clock on the evening of January 2, a fire broke out in Dehui International Plaza in Urumqi. At present, the fire continues to spread, and firefighters at the scene are still struggling to rescue. Xinhua News Agency reporter Faye Wong photo

　　　 On January 5, the first squadron of the special service to which the three martyrs belonged lost their usual atmosphere, and the soldiers all looked dignified. Speaking of the sacrificed comrades, instructor Jiang Shaojie choked several times, and Zheng Jie, a little soldier who just turned 18, burst into tears.

　　　 In the dormitory of three martyrs, their quilts were folded like tofu as usual. The comrades-in-arms pulled the flat sheets again and again. Wang Li, who had been regretting that he could not save the peak, touched the cotton cap of the peak and was silent.

　　　 "Brother is gone, I’ll take the top!" Zhang Shuai, Zhangyu’s younger brother, learned that his brother died in the fire fighting, and vowed with tears to carry on his brother’s legacy and become a fire fighter.

　　　 Lan Can, a political commissar, still clearly remembers Zhu Xiaolei’s meeting on the day he came home from vacation. "I told him to find a daughter-in-law quickly and stop dangling in front of me. He said,’ I will definitely finish the task for you in 2008!’ "Lancan suddenly hid his face and wept:" Did I say something wrong? Tell him to stop dangling … "

　　　 Like the three martyrs, most of the fire officers and soldiers of the first squadron of the Secret Service have no girlfriends. "Can’t, we basically don’t go out, always on standby. Besides, which girl wants to associate with a man who lives and dies almost every day. " A soldier said.

　　　 The dead are gone, and the living still have a long way to go. Wang Li said: "They are lying down, and we will continue to work. Our task has not been completed."

　　　 After saying his word, a shrill alarm suddenly sounded, and Wang Li bounced off the stool like a reflex and rushed out of the door, but the reporters who had not recovered looked at each other. In an instant, the fire truck has rushed out of the gate.

Moreover, this kind of transmission is direct enough and efficient enough, and it is like a master who never drags his feet … but why is it fast? Why is it efficient? What is its control principle? Is it really advanced? Want to know the answer? You don’t have to go to Baidu. car home has already opened powershift’s coat for you here-ladies and gentlemen, look for the answers you want in front of the naked transmission.

> > > Special note: 1. This paper only dissembles the DSG gearbox objectively, and does not comment on the phenomenon.

　　2. Regarding the topic of stability and fault that users are concerned about, we will explain it for you in the following follow-up articles. There is a notice at the end of the article. Please leave a message and participate in the discussion if you have any questions or faults about the dual clutch gearbox!

　　As usual, first of all, briefly introduce the protagonist of this "dedication": Volkswagen DQ200 dual-clutch gearbox-the first Volkswagen DSG gearbox made in China.

● Get familiar with DQ200 gearbox quickly? Manual gearbox? Dual clutch gearbox?

　　Before we begin, we need to form an awareness of the dual-clutch gearbox in our consciousness. If you still don’t know what the gearbox is and how the basic manual gearbox works, we have prepared the following aperitif wine for you, please taste it first.

　　After understanding the structure of the manual gearbox, it is much simpler for us to understand the dual-clutch gearbox. In principle, the dual-clutch gearbox is equivalent to the combination of two manual gearboxes, one controls the odd gear, the other controls the even gear, and the reverse gear is queued according to the situation (in the DQ200 7-speed dual-clutch gearbox, the reverse gear is regarded as a group with the even gear). Then, one set can be added to the combination of these two manual gearboxes. Hong Gong, a well-known Volkswagen engineer in the media circle, used "two manual boxes and one set of automatic dialing" to vividly compare the principle of dual-clutch gearbox. The following video will help you to understand our metaphor more intuitively, and also help you to face the various parts that will be disassembled from DQ200 more calmly.

"『DQ200 gearbox principle demonstration video-in order to save your time, it is suggested thatAfter 1 minute and 12 seconds,Start watching "

　　With regard to the origin and evolution history of the concept of "dual clutch", we also give it to you as an appetizer. Please click the link below to see the ups and downs of the dual clutch so far.

● Actual disassembly of DQ200 transmission: three modules-two "powerful" and one "calculated"

　　Metaphor is metaphor. When we really put DQ200 in front of you, you can’t really see a product that is directly combined with "two manual gearboxes and one controller". The previous section is only for everyone to understand the principle of dual-clutch gearbox.

　　Judging from the actual structure of the gearbox, the main number of members of DQ200 powershift is still "three" (of course not MT+MT+ controller …). These three modules have different division of labor, and two of them are only responsible for "hard work". They are dual clutch modules and gearbox parts, and all they have to do is to transmit power, commonly known as "force". The third part is the "source of wisdom" of the dual-clutch gearbox-the electromechanical control module, but in fact it is both mental and physical-it can be said that it is both a director and an actor. What are the specific tasks and characteristics of these three modules? We interpret it by disassembling it.

● Dual clutch module: I have a foreign ID card!

　　Let’s get to know the dual clutch module with German ID on DQ200. Since powershift took his last name, you can imagine how important this guy is.

"The dual clutch module is provided by the Luk brand of Schaeffler, Germany."

　　The dual clutch module is simply two sets of clutches+one shell. We call the clutch near one end of the engine K1 clutch, and the clutch behind it K2 clutch. The two sets of clutches K1 and K2 have their own independent driven parts (friction plate+driven plate+shock absorber+driven hub), pressing mechanism (diaphragm spring, pressure plate) and operating mechanism (only the operating arm is mentioned here).

　　The double clutch housing, the driving disc in the middle of the housing, and the butterfly diaphragm springs and pressure plates of K1 and K2 are all "best friends" of the engine, and there is no relative rotation between them. The double clutch housing is connected with the engine flywheel and rotates synchronously with the engine, and these components are called "driving parts".

　　The diaphragm spring and pressure plate which rotate together with the clutch housing play an important role. Under the lever action of the control arm, the sleeve is pressed to deform the diaphragm spring, and the resulting deformation pushes (or pulls) the pressure plate to press the friction plate. At this time, the driven plate and the aforementioned driving part become a whole. With the synchronous rotation of the engine, after the power is obtained from the clutch, the driven plate relies on the internal spline to transfer the power to the input shaft, and the power from the engine enters the gearbox.

● What you don’t know about DQ200(1)
-The working principle of the clutch is the same as that of the manual gearbox, but it works in the opposite way!

　　Speaking of butterfly diaphragm spring, I have to say that this DQ200 dry dual clutch is very interesting in control mode and principle. It is consistent with the familiar manual gearbox principle, which also relies on extrusion and friction to realize the continuous transmission of power, and also uses the lever principle to squeeze the sleeve to deform the diaphragm spring. However, the diaphragm spring works in the opposite way to the diaphragm spring in the manual transmission clutch (see the dynamic diagram above). In the single-chip clutch structure of manual transmission, when the diaphragm spring is squeezed, the clutch pressure plate will be released and the power transmission will be interrupted; In DQ200 gearbox, the function of diaphragm spring when it is squeezed is actually to press the clutch to turn on the power! To put it bluntly, the clutch of the manual gearbox is-You give an external force, it separates,The clutch of this DQ200 dual-clutch gearbox is just the opposite.You give an external force, it will engage!The "disengaging bearing" and "disengaging lever" in the traditional clutch should be renamed as "engaging" XX here. …

● Gear box: double MT combined body

　　After the power enters the gearbox from the input shaft, it will begin to travel between gears. The gear camp in the box is very easy to divide-like two sets of manual gearboxes-two input shafts and two output shafts, and then a set of parking locking mechanism and a differential to transmit power to the wheel axle are added. In this way, you will find that the dual-clutch gearbox is actually just a few more shafts than the traditional manual gearbox. As we have previewed before, the shifting principle of DQ200 and manual gearbox is completely consistent, and the shifting fork pushes the engaging gear sleeve to complete the combination or separation of gears (shifting gears).

　　The two input shafts are respectively connected with the K1 clutch and the K2 clutch, and the internal and external coupling mode is adopted. The first input shaft is equipped with a 1357th gear, and the second input shaft is equipped with a 246R gear. When the two clutches work alternately, the power can be connected between the odd gear and the even gear. Take a closer look at the input shaft, and you will find another interesting thing. On the first input shaft, the gears corresponding to the 1357th gear are independent, while the second input shaft corresponding to the 246R gear has only two gears. The 4th gear and the 6th gear share one input shaft gear, and the 2nd gear and the R gear (reverse gear) share one input shaft gear. Perhaps the purpose of this design is to ensure that the hollow second input shaft can have enough strength and ensure the gearbox.

● What you don’t know about DQ200 gearbox (2)
-What’s the difference between the "N" gear (neutral gear) of the dual clutch gearbox and the manual gearbox?

　　Many netizens want to know the difference between the "N" gear of the dual clutch gearbox and the neutral gear of the manual gearbox. Take the DQ200 gearbox we disassembled as an example. Its logic in the "N" gear is indeed different from the "neutral" of our usual manual gearbox. Simply put,The "neutral" of the dual clutch gearbox is equivalent to the state that the manual gearbox is "engaged in 1st gear and engaged"., so that the speed will be faster when the power is engaged. Moreover, in the D-range mode, when the brake is stepped on for a long time, the clutch will also be automatically disconnected, and the gear engaging sleeve is still engaged with the 1st gear.

　　In addition to various shafts and gears, the gearbox body also has a part that we can’t ignore-the parking control module, that is, the "P" gear control mechanism of our vehicle. The parking gear is integrated on the third output shaft, coaxial with the reverse gear, and it is the only gear with internal splines (synchronized with the output shaft).

　　The parking control mechanism is the only one physically connected with the gear lever on the DQ200 gearbox (all other controls are transmitted by electrical signals). When we put the gear lever into the "P" gear, the gear lever is controlled by the cable, and the connecting ball pin is pulled to make the pawl buckle the parking gear, thus locking the output shaft and achieving the purpose of parking locking.

● Electromechanical control module, with developed "six limbs" and not simple mind.

　　The hardest part of the three is naturally the electromechanical control module, which is "both output and calculation". This way of working is simply a typical "IT migrant worker".

　　From the structural point of view, its composition is not complicated. The sensor, arithmetic/control chip, hydraulic unit and actuator are just four pieces of content, which is also a simple number. The electromechanical control module relies on these components to complete the whole process of obtaining information-judgment/decision-making-execution. Among them, the hydraulic pump and pressure storage tank composed of gear pump are the source of all power for the electromechanical control module, and if human organs are used as an analogy, this is the heart.

　　We humans move through four limbs. The electromechanical control module of DQ200 has six limbs, which control the operating arms of K1 and K2 clutches respectively, and the other four limbs are used to control the shift fork. Four independent fork control levers control five forks (six gears and reverse gears are two forks sharing a fork control lever), and it is the existence of independent control levers that makes it possible to engage adjacent gears in advance.

　　The "brain" that gives action instructions to limbs is provided by Continental, Germany. This brain judges the driving state of the vehicle and the driver’s intention through the engine speed sensor, the output shaft speed sensor and the operation made by the driver on the gearbox control lever, and shares a series of information on the CANBUS bus, such as vehicle speed, wheel speed, accelerator pedal position, steering angle sensor, lateral acceleration sensor and so on, and makes a response. Sensors located at the fork and clutch actuator always remind the German brain of the clutch that the gearbox is currently working and the gear that is currently combined. At the same time, according to the oil temperature sensor and oil pressure sensor in the electromechanical control module, whether the working state of the gearbox is normal or not can be monitored in time. We can imagine that this information processing ability is hopeful to challenge the popular dual-core smart phone …

● What you don’t know about DQ200 gearbox (3)
-even without a double clutch, it can be fast!

　　The reason why the dual clutch gearbox is fast enough is not only because it is as simple as a "dual clutch module", but also largely due to its independent shift control lever. Do you know what "independence" means? This means that even if there is no double clutch, since DQ200 adopts the design that the interval gears share a joint sleeve (as mentioned above), the joint sleeves of adjacent gears can operate independently, and theoretically, "the joint sleeves of one gear can be disengaged while the joint sleeves of adjacent gears are engaged!" Do you know what is the core system of Lamborghini’s ISR gearbox (the gearbox with a shift time of 50 milliseconds)? In fact, it is a number of forks that can be controlled independently!

"The reason why Lamborghini’s ISR gearbox dares to challenge the serial gearboxes of the previous supercars.
It is also because it adopts an independently controlled shift fork.

　　(This paragraph is purely for discussion, and fans are welcome to speak enthusiastically.) The effect of this independent control is more flexible than that of the mechanical multi-fork synchronous action mode relying on the "shift drum" of the sequential gearbox, especially in the case of "trip stop" (except for odd-numbered trip stop …), while the shift drum mechanism can quickly switch between adjacent gears by relying on the servo motor with quick response, but when multiple gears are shifted up or down (for example,

● DQ200(4 you don’t know (4)
-the gearbox needs to use two kinds of oil at the same time!

　　Most automatic gearboxes and even dual-clutch gearboxes only use one kind of oil, which not only needs to realize the functions of lubrication, heat dissipation and torque transmission, but also needs to provide the hydraulic pressure required by hydraulic control components. DQ200 dual-clutch gearbox adopts independent dual-oil circuit design, and different oils are applied in the two oil circuits. In the gearbox, the gear oil of model G052171 is used, which is consistent with the gear oil used in the domestic Volkswagen MQ250 manual gearbox, while the hydraulic oil of model G004000 is used in the electromechanical control module. The two oils can better play their own functions in their independent oil circuit circulation, so that the gearbox has better low-temperature working characteristics.

　　Moreover, the total oil consumption of DQ200 is only 2.7L (1.7L of gear oil and 1L of hydraulic oil), which is nearly half of that of traditional automatic gearbox and wet dual-clutch gearbox. Needless to say, DQ200 is a maintenance-free design, even if it needs maintenance later, it has obvious advantages in cost. (It is said that the oil consumption of DQ250 wet dual clutch gearbox is more than 6L, and the total oil consumption of DQ200 is less than half.)

-What’s the difference between DQ200 (7-speed dry dual clutch) and DQ250(6-speed wet dual clutch)?

　　I believe everyone knows the most obvious difference between DQ200 and DQ250, that is, the difference between "wet and dry" clutches. DQ250 uses a wet clutch, and the control method of the clutch is completely different. DQ200 relies on hydraulic pressure to push the control arm and presses the clutch plate by the diaphragm spring, while the clutch engagement of DQ250 is completely controlled by hydraulic pressure. DQ250 designed with a wet clutch uses a single oil, because of its large consumption. Therefore, the oil tank is designed, and it has pressure oil filter, oil cooler and oil pump driven by crankshaft power, which DQ200 does not have.

　　In addition, due to the different number of forward gears, the 7-speed DQ200 has three output shafts, the reverse gear and the parking gear alone occupy one output shaft, while the DQ250 has only two, and the parking gear of DQ250 is integrated on the differential.

Summary:

　　After reading the disassembly article of DQ200, I believe everyone has a deeper understanding and cognition of this 7-speed dry dual-clutch gearbox.Personally, the dual clutch gearbox is not complicated in principle or structure, and the structure based on manual gearbox is the fundamental reason for its high transmission efficiency and low fuel consumption.The design idea of DQ200 dual oil circuit and dual oil is one of its highlights. The two independent oils have more advantages in functional adaptability, and the total oil consumption of 2.7L is also a figure worth showing off.

　　Of course, all advanced and fresh technologies always need to face people’s doubts and challenges, and our users still have various questions about "dual clutch". In the next article, we will answer the hot issues of gearbox reliability, price, maintenance and so on that are concerned by the majority of riders, and present more "DQ200 dual clutch gearbox you don’t know" for you.

Unlike the last entrepreneurial project in mobike, Xia Yiping failed to get a decent ending in the extreme.

The "in-situ dissolution" of Extreme Yue may have brought the biggest traffic to the brand since its establishment, and the incident is still continuing to ferment.On December 16th, Xia Yiping, CEO of Jiyue, published a long article in the circle of friends, clarifying the rumor of "running away" and reflecting on all the mistakes made in the process of starting a business. "Wrong, it’s all my fault".

Extremely more recent can cause such great concern, which has a lot to do with the sudden dissolution.Prior to this, Weimar, Gaohe and other closed new car companies had never been dissolved so quickly.

There are different opinions about the whole incident. Beyond the complicated information, the next question that the outside world cares about is, is there a future in the extreme?

Dissolution in situ is a "forced palace" Baidu?

Simply put,The reason why I can’t support it is that I have no money.And Baidu, the dominant shareholder, does not intend to continue investing.

It has been reported that Jiyue owes several billion yuan to Geely and Baidu for OEM fees and smart driving programs. In addition, many suppliers have issued open letters to Extremely Vietnam asking for arrears.

"Financing should have been my most important duty, but I was too optimistic in the early days and did not foresee the seriousness of the funding problem." Xia Yiping pointed out in a long article.

However, from another perspective, Baidu and Geely, as major shareholders, should have blood transfusions when they are in extreme difficulties. So,Whether Xia Yiping’s description of financing is a reflection or a "connotation" of major shareholders can be interpreted in many ways.

From 2021, Baidu officially announced the construction of a car, and now it has ended hastily. There seems to be a trace of the extreme failure, which itself is a twist.

As the dominant party, Baidu did not take a firm attitude in building a car. Li Yanhong himself did not intend to personally lead the team to build a car, which is very different from Lei Jun and Li Bin. For such a complicated car-making project, the person in charge of the enterprise personally leads the team and still has a high probability of failure, let alone being a "hands-on shopkeeper".

Geely, another shareholder, is more like a foundry. At present, it is catching up with Geely’s strategic contraction, and naturally it will not make a big deal on the new round of financing. Geely has many brands in its own layout, and it seems that it will not have enough time to worry about this "illegitimate child".

Xia Yiping, the helm of Chaoyue, is more like a professional manager than an entrepreneur. Although Xia Yiping pointed out in his long article that he invested "the savings accumulated in his last venture" in Vietnam, he regarded himself as "a real entrepreneur." But in any case, he is more like the deputy of the shopkeeper Li Yanhong. Xia Yiping is naturally to blame for the financial crisis in Vietnam, but he also has a passive place.

Therefore, regarding the abnormal operation of "dissolving in place", there are also interpretations that this is a "forced palace" for Baidu. When a mass incident such as "extreme employees ask for salary" and "car main statement" broke out, Baidu had to come forward to take out funds to solve the problem.

Fortunately, some issues that employees and car owners are concerned about finally got an official response. On December 13, Baidu Holdings and Geely Holding issued a joint statement, which will cover the dissolution of the company and solve the problems including the disposal of employees and the after-sales of vehicles. According to the public information released by Yang Xueliang, senior vice president of Geely Holding Group, Geely is responsible for the after-sales service of vehicles.

Is there a future for Ji Yue?

After the crisis in Vietnam, outsiders have given up much hope for the future of this brand.However, there are still some entrants, such as the staff and the owner of the company, who still have a little "fantasy" about the prospect of the company.

Can Ji Yue still hold on? We can find some answers from the joint statement of Baidu and Geely and Xia Yiping’s long article.

Judging from the statements issued by Baidu and Geely Holding, it is already an attitude of "taking care of the aftermath", and the focus has been put down on dealing with matters such as employee social security payment, the aftermath of resigned employees, and after-sales maintenance of vehicles. For financing and other important measures to support the development of enterprises, the two major shareholders did not mention a word.

As for Xia Yiping’s long article, there is no substance except reflection. "I have learned a lot of lessons that will be used in the future development of the company or other entrepreneurial growth in the next step." He pointed out in a long article. Considering that Xia Yiping has made many mistakes in the development of the company, if there is a bright future, it is highly probable that it has nothing to do with him. So,The "future development of the company" mentioned in the long article is false, and "other entrepreneurial growth" is true.

Is there a way out for the enterprises that the major shareholders and the top management have given up? The answer is self-evident.

In this regard, Yang Yueqing, the project director of Gaohe Engineering, who is a "experienced person", has previously released a video to give suggestions to the employees: you can leave early and don’t have illusions.

Then, from the perspective of other external investors, is Extreme Yue a good target?

First of all, Extreme Yue is not a strong brand in the market. At present, Extreme Vietnam has launched two models, 07. The product itself has some remarkable advantages, such as product quality and design, but the design without door handle and half steering wheel has also caused a lot of complaints. The market performance of the two cars is not good, which basically belongs to the existence of small and transparent rims.

In addition, the receiver has to face a thorny problem:If Geely is no longer OEM, the problem of the qualification of making a car in Extreme Vietnam needs to be solved.Previously, the ultra-Vietnam has experienced the replacement from "concentration" to "ultra-Vietnam" in order to avoid the qualification problem. This adjustment has also wasted a lot of publicity resources. If new investors are introduced, the brand name of "Jiyue" registered by Geely may have to undergo another replacement.

From the perspective of the big environment, the car has also been at the end of the tuyere. In March 2021, Xiaomi, who officially announced the car, was called the last entrant in the industry. If investors want to take over at this time, they really need two brushes.

Write at the end:

In this round of crisis, employees and car owners may be the most injured groups. Many people were still working overtime the day before, or celebrating the new car. The next day, the company suddenly dissolved.

Judging from the current situation, Ji Yue is not the first new force car company to explode mines, and it will not be the last one.With such a "lesson from the past", I only hope that consumers and "workers" can do less harm in similar incidents in the future.
