Original jojo, great craftsman

When Xiaobian contacted Mr. Yamayama,

Colleagues are very excited.

Everyone is interested in this up master with outstanding style in bilibili knowledge area.

I have accumulated enough curiosity.

He is well-educated and insane.

Claiming to be "a Chinese slacker, a drunkard in Jiannan Road"

His outrageous behavior includes reading "Please Wu Zhao" in the street.

Shoot one’s own portrait

Imitate Wei and Jin Dynasties to swallow homemade Wushi Powder.

Results Sulfur poisoning.

His video, besides the hard-core ancient prose analysis,

It is even more exciting, and it is spontaneous.

This issue of "Great Craftsman"

Show you all the secrets of Mr. Yamayama.

● Mr. Yamayama

Bilibili Million Fans Upmaster

● "Writing for Trump and Biden" by Mr. Youshan

Selected as a must-see video for the 2020 Knowledge Zone.

When Li Peiran

It’s not "Mr. Yamayama"

Mr. Youshan’s real name is Li Peiran

Born in a poor farming family in western Sichuan.

Claiming that parents have suffered from illiteracy.

I forced him to recite in kindergarten.

Three hundred Tang Poems by Heng Tangju Shi

Elementary school has to recite Wu’s uncle’s "The View of Ancient Chinese Literature"

Such forced training

So that junior high school students can write classical Chinese without penetrating or affectation.

Even more exaggerated is that

High school began to write in a dazzling way.

The first paragraph uses the Book of Songs, the second paragraph uses Chu Ci, and the third paragraph uses Han Fu.

The fourth paragraph uses Tang poetry, the fifth paragraph uses Song ci, and the sixth paragraph uses Yuanqu.

Finally, the style of Ming and Qing novels is summarized.

In an article, it has gone through five thousand years.

No wonder he prides himself on being like Li Bai.

Li Bai can’t surpass his time.

But Li Peiran, from the perspective of 2022,

Can make the essence of 5,000 years of cultural cultivation work for yourself.

But he is extremely eccentric.

With the existing achievements, it is definitely impossible to enter an ideal university.

In 2017, Li Peiran took the college entrance examination.

It happened that the topic of the composition was "I watch the college entrance examination"

In his view, this topic is like a provocation.

He wrote a composition that was eloquent but doomed to zero.

Attacking the college entrance examination system is the contemporary stereotyped writing for candidates.

Finally fell out of the list

Can’t find the ideal position in the real world

He is full of talent and consciousness.

Began to have the idea of seclusion

"This is the only living classical Chinese writer I have ever seen.

But he has a photo. "

Li Peiran failed in the college entrance examination.

Follow the example of "Mr. Wuliu" and retire to the countryside

And call himself "Mr. Yamayama"

Although like Tao Yuanming, he plowed and studied hard.

However, he has no agricultural foundation, and the fields he grows are "grass is abundant and beans are scarce"

In the mountains, "five days of bamboo is boring, and ten days of birds are boring."

After living in seclusion for two years.

He decided to go down the mountain and find another way out

Mr. Yamayama in seclusion

Youshan was once the son of Qian Mu, a master of Chinese studies.

Professor Tsinghua University Qian Xun studied for seven days.

When asked what Professor Qian Xun thought of "hermits"

I thought Professor Qian Xun would praise him for not wanting fame and fortune.

I didn’t expect Professor Qian Xun to say:

"This is the misfortune of the times,

Is the sorrow of the country,

Because the country’s brain drain. "

● Mr. Yamayama and Professor Qian Xun

Being called a talent by a master of Chinese studies inspired Yamayama.

You know, because you’re a maverick

People around him thought he was crazy since childhood.

There are mountains that are encouraged.

Started releasing videos about ancient literature in bilibili.

When explaining poetry and prose

He quoted classics and often added some unpopular knowledge.

Can restore the situation at that time more accurately

Under his interpretation, those ancient celebrities and great talents

Also become vivid and close.

Recitation of ancient poems with mountains

Pay great attention to the rhythm of sentence breaking and the ups and downs of emotion

Strive to resonate with the original to achieve artistic conception

● The poetic interaction between Mr. Youshan and bilibili netizens.

There are mountains now

Already has over a million fans.

Already the head of bilibili knowledge area up master.

Many teachers play his recitation videos in class.

His article was selected as a Chinese reading topic by a school.

More times on the stage of Henan Satellite TV and Shandong Satellite TV.

Like a famous Chinese scholar.

?

Mr. Youshan’s message to college entrance examination students: the college entrance examination can’t determine life, so we should establish an equal career concept.

?

You think your talent is comparable to that of Li Bai, so what do you think of the relationship between talent and hard work?

I think my talent is not very good, although I act like a cynic, looking very carefree, drinking wine, enjoying myself, being naive and laughing.

In fact, I am a workaholic. My day is 36 hours, because I have no biological state at all. I open my eyes for 28 hours and sleep for 8 hours every day.

● Mr. Yamayama’s library.

Can you tell us something about the process of creating bilibili video?

The most important thing is inspiration. When there is no inspiration, I will not make a video by force, which is soulless. After inspiration, it usually takes two days to write a copy first, and then shoot.

Shooting is the most painful thing for me. For example, I may have to record a video analyzing ancient Chinese prose forty or fifty times. For a 1,000-word manuscript, I have to make sure that I recite it exactly, and the emotional ups and downs are in line with the artistic conception of the article, so I need to constantly re-record it.

Finally, editing, my video clips are very few, and I hope to present a mirror in a more natural state.

You are drinking in the video, lying on the ground while talking, etc. Are these designed or naturally revealed?

I am an up master who has no one to set up, because people will inevitably collapse.

What I look like in real life is what I look like in the video. The only difference is that I am more arrogant in reality. When I drink wine and talk to everyone, I will talk loudly. In the video, I am more low-key. As a public figure, I still need something relatively positive.

● Writing in classical Chinese closely following current events.

What do you think is the greatest charm of traditional culture?

Studying traditional culture will really have a sense of reverence, a sense of shock and a sense of mission.

Why do you do such maverick things as taking photos and taking Wushisan?

It stems from the detached attitude towards life and death, which is also influenced by Zhuangzi’s "drum basin and song".

I look down on fame, life and death.

Looking down on life and death does not mean that you are not afraid of death. Looking down on fame does not mean that you don’t like or want fame. I cherish my life. I can’t live in poverty. I want to be happier. If you give me more money, I won’t refuse.

● Mr. Yamayama shows his photo.

Nowadays, many young people wander around in involution and decay. Do you have any suggestions for them?

Suggest that they read The Doctrine of the Mean, and read Zhuangzi and Lao Zi. Taoism emphasizes inaction, but it is by no means bad.

Zhuangzi said that Zhou will be between doing and not doing, and doing and not doing should be analyzed in detail. It is a dynamic balance, and the so-called Tao is just like this.

Who is your favorite ancient celebrity? Why?

Zhuangzi.

If there is a chance for me to meet Zhuangzi, I would go to the primitive world.

What kind of role will you try in the future if the up master is not popular one day?

Everything has a life cycle, and saints will be remembered one day, not to mention an ordinary person like me.

If one day, I should be a teacher. My hobby is teaching and educating people.

● Mr. Youshan in the period of traveling.

What do you think is the most perfect happiness?

Free, rich, respected by the world and future generations.

What kind of talent do you want most?

Pick up hot chicks’s ability.

What do you fear most?

Be remembered by future generations.

What’s your current state of mind?

A little haggard and very tired.

Who do you admire most among the living people?

Myself.

What do you think is your greatest achievement?

He has created many classic articles handed down from generation to generation.

After 1000 years, it will definitely be learned by everyone.

There won’t be any accidents,

I have firm confidence in this.

What characteristics of yourself do you hate the most?

I don’t hate myself.

I think I can be more handsome. I have appearance anxiety.

What’s your favorite trip?

The time I went to Daocheng Aden,

At that time, I was not the upmaster,

The journey is relatively pure.

What characteristics do you hate most about others?

Hypocrisy

What is your most treasured property?

The money in my bank.

What is your greatest luxury?

Going to bed one night,

I woke up with a nosebleed and didn’t want to get up to get toilet paper.

From the "Ming History" on the bedside.

Tear a few pages to stop the bleeding temporarily.

What do you think is the shallowest pain?

There are no big rivers in Chengdu, so you can’t feel the magnificent beauty.

Which virtue do you think is overrated?

Economy.

What’s your favorite occupation?

Teacher.

What are you dissatisfied with your appearance?

The back of my head is peaceful.

What do you regret most?

At the beginning of this year, a business order was not received.

That list is quite rich.

Who do you despise most among the living people?

My primary school math teacher,

Once I got 100 points in math,

He framed me for cheating.

He doesn’t have any evidence,

Criticize me in front of the whole class,

And call my parents.

What is your most painful thing?

I ate homemade Wushi powder,

Results I went to the hospital for gastric lavage.

It was the most painful thirty minutes of my life.

What is the person or thing you love most in your life?

My book.

How do you want to die?

Natural death.

When and where do you feel happiest?

Drink, just drunk

I’m happiest when I’m not sick.

If you could change one thing about your family, what would it be?

I hope my father is a rich man,

Or a leading cadre.

If you had a choice, what would you like to reproduce?

See Zhuangzi.

What is your motto?

Foolishly adorn my watch, but hide it in decay.

Appendix: Appreciation of Mr. Youshan’s Strange Articles

"For King Luo Bin, for Xu Jingye"

Jun chi thousands of miles away, there is no distinction between males and females; Wang Yuzhaomin still has a distinction between good and evil. Lv Hou’s trouble with the Huns was the beginning of Wen Jing; Wu’s guilt in Shangyuan is anger and arrogance. Sacrifice two emperors, kill ministers, and Luo Zhi is all over the world, creating a chaotic octupole. Dabao is broken for it, and the artifact is smashed for it. The soil is cloudy in the haze, and the ordinary man is afraid of the sword.

Sikong mowgli, three dynasties old, the British crown outstanding. He died suddenly and violently, and he helped the emperor and entrusted his life. Wu’s bribery was not accepted, and he was convicted and demoted to death in Guizhou, which made Yu sad. Servants are good at shooting, loyal to the country, demoralized, and severely criticized. Once this Lao was culled, the soul broke off in South Vietnam, and it was also a whale giant. So Jane pulled out the night and made a cruel official. Softly imprison Di Zi, and reuse consorts. In addition to destroying the branches, it eats the court. Take a fierce prison and kill people, set up a bronze plaque and cover Tang Ding. Therefore, the official was tongue-tied, the scholar’s jaw was closed, the water board was wordless, and the admonisher lost his voice.

Wu’s thief is busy with the power of heaven, and he is unconscious and disabled. Qi Ji was spared the meat of the jar altar, and Gao Wei did not slaughter the infant baby. Not only punish Wang Sun, but also cut off Li Min. Welcome Buddha’s bone in Chixian County, and move the foundation of Confucianism and Taoism; Move the Purple Palace to Luoyang, exhausting the sweat of Qianshou. Xiao Yan’s decline is sad to see; The death of Dong Zhuo is a great pain. The tower outside the temple is empty and foolish; Luxurious buildings and huge halls are only a waste of money. Whoo! The state’s family is bitter, and the people are poor.

As for the worship of Zen in Songshan Mountain, Taiyue is disrespectful, and his back is far and wide, and he abandons his faith and does Kun. Tubo disturbed Anxi, and Turkic committed it in Mobei. Zhenguan was not sacrificed because of Liaodong, and Wu Shi was honored as a stiff skeleton. It also favors the face, makes the second class dimension, sets fire to the hall, and manipulates power. Then there are people who have cracked the temples inside, people who have rushed to the crown outside, the prophecy of the dry Sichuan below, and the star who attacked the moon above.

My Lord Xu Jingye, an old minister of Li Tang, is benevolent and resourceful, and vows to get rid of surliness. Drink the fast waves of the Hanjiang River and shake the righteous flag of Yangzhou. Planning is the same as heaven and man, and washing the blade is the fear of ghosts and gods. Soldiers array, direct drive Luo Lu, roaring tigers and dragons, exploding thunder and thunderbolts. Flying troops shake mountains and shoot snow with long knives, riding horses and chasing the wind, while Wu Ge shines on the sun. Sun Bin is unstoppable, and Yafu is irresistible. The sea is flooded with fireflies, and the iron falls into spring ice.

Gaiwen: Ju Shou died of Yuan’s family, so it is better for Gao Lan to surrender Cao; Zhang Ren was trapped in Luocheng, but he did not obey Han Yan Yan. The number of false spirits is exhausted, and it will be rectified in a few days. Is to wait until the sandstorm stops, the world is clear, and the ninth Five-Year Plan is given priority, and then the country is worked.

He who wins the head of the witch will be rewarded with 80 million yuan and sealed 8 thousand households. Moving to the county, such as the law!

Dayefu

Opium is poisonous and drunk; Chen Meng won’t wake up until the ship is on the shore. At this time, Kyushu was soft and the Central Plains was weak. The wind is full of evil, and the rain is full of evil. Foreign countries are arrogant and arrogant, and they cut down the soil; The Qing court was corrupt and weak, and peddled the people. Cut the city and abandon the soil, why cherish the accumulation of the future generations; Qiaoyuan practices the temple, who pity the hundred generations to pass on the roses? Or there are strong men who hold their wrists, fierce ministers who beat them, and change their methods into weapons, but they will never recover. Therefore, China is in trouble, and Chixian County is on the verge of extinction. Huang Zu cried with ghosts and gods, and the head of Guizhou died with the hen. Alas!

When Guangzhou dialed the blood bell, Wuchang raised the banner of righteousness, and the Imperial Mansion collapsed, the iron drums shook in ten provinces. Burning ointment in the sea, washing the color in the world, democratic Republic, and gradually gaining popularity. However, Yuan’s stealing treasures is not a success. Song Jun was assassinated, which is called "overwork"? The concept of arrogance is in the way, sighing that Confucius and Mencius have no hometown. Bad politics and alcohol people, foreigners and landlords. Sadly, short candles don’t shine on the darkness of the atlas; Pain also zai, residual fireflies can’t warm large chunks of cold.

In 1921, at the age of 18, I was in Xinyou, showing a picture of the South Lake and painting a boat. Following the May 4th Movement, we carried forward the principles of Marxism-Leninism. Shoot jade electricity and break the fog, blow boiling songs and melt ice. Chen Lixiong wrote, raising huge waves to ask about the reef of barnacles; Zhang Zhou struggled to wipe the wall of moss in Tai ‘a. Then, I will attack the crime directly, strengthen the martial arts, take the mud pill of Xichuan, and resist the jackal of the East Island. Conquer violence against disasters and save refugees from beasts. Yang Zhao died without changing his heart, Zhu Peng attacked Japan and the Blue Army solved Eritrea. So the workers and peasants combined, the sickle and hammer danced, the coward’s house collapsed, and Chiang’s family fled. Defeat Korea, defeat the United States and disable Europe; Drive India, suppress the empire and greedy wolves. How strong our party is! Sincerely sweep away the embarrassment of a hundred years and promote the health of all generations.

Today I am Chinese, people-oriented, reform and opening up. Collect the land, scatter the beaver, light the apricot altar, and cultivate the middle beam. The wonderful politics of the past year, dropping out of agriculture and giving it to Xiao Guicheng; Attract the wealth of foreign countries, and the treasury is spared. Shovel mountains, endless forests; The boat draws a lot of water, so don’t take the mysterious seedlings. The stars are flying in the silver Han, and the boat is involved in the long deep, but it is known that the dragon and phoenix are dead; The road is snowy, the road is far away, but the businessmen are not falling. From all walks of life, the people are safe. High-rise buildings soar, and huge buildings soar. Qian Lao donated his life, but the nuclear error was gone, and yuangong died, but the food shortage was gone forever. The roar of the three armies will break the waves in four oceans, and the laughter of a billion husbands will make seven States become the wind. Awesome in the heart, quick in the liver and intestines. Flood damages thousands of miles and destroys them, and Yu De can shoulder it; The earthquake moved eight levels without falling, and the soul can be marked. Anti-corruption, up and down, anti-epidemic North-South Concord. Poverty alleviation is carried out simultaneously, and the country is United in ancient and modern times!

In 2021, the centennial birthday of our party was heard by people who witnessed it. Fortunately, even zai, song to congratulate!

　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.

Text/Zhou Daoxu Director of Financial Security Research Center of Tsinghua University Wudaokou Finance College

Capital market is essentially an information market, and enterprise value is continuously priced in information interaction. When the crisis of public opinion occurs, the sudden change of information environment will trigger the market to re-evaluate the fundamentals of enterprises.

First, the financial transmission mechanism of public opinion shock

The surge in the cost of information verification is the primary transmission channel. When an enterprise is caught in a crisis of public opinion, the market will doubt the authenticity of its information disclosure, and investors need to invest additional resources for due diligence, including consulting financial statements, analyzing industry data, and referring to third-party audit opinions. This extra verification cost will reduce market liquidity and may lead some investors to choose to withdraw from the market because of information asymmetry. At the same time, institutional investors may adjust their investment portfolio to reduce the risk exposure related to the enterprise, thus triggering a further decline in the stock price.

In addition, the intensification of information asymmetry will lead to an increase in the market’s risk premium requirements for enterprises. When faced with information uncertainty, investors often demand higher risk compensation to make up for potential losses. The rise of this risk premium will not only be directly reflected in the decline of the company’s share price, but also affect the financing cost of the company, which will challenge its refinancing ability in the capital market. In extreme cases, enterprises may fall into a liquidity crisis due to the loss of market trust, and even go bankrupt and reorganize.

The dynamic adjustment of credit rating forms the second pressure. In the face of major public opinion crisis, rating agencies usually quickly adjust their credit ratings to reflect the latest market awareness of corporate credit status. However, the adjustment of rating agencies is often characterized by "over-revision", that is, a large downward adjustment in a short period of time to avoid their own reputation risks. This rating adjustment not only affects the debt financing cost of enterprises, but also may trigger a chain reaction in the bond market, leading to sharp fluctuations in bond prices.

The downgrade of credit rating may also trigger the "cross-default" clause in the financial market, that is, some loan or debt agreements of enterprises may stipulate that once the credit rating falls below a certain level, enterprises need to repay debts in advance or provide additional guarantees. This means that enterprises may face sudden cash flow pressure after the public opinion crisis, further aggravating the deterioration of their financial situation. This chain reaction will amplify the market’s concerns about the fundamentals of enterprises, and may even lead enterprises to enter debt restructuring or bankruptcy procedures.

Second, the empirical analysis of typical cases

In April 2020, Luckin Coffee’s self-disclosure of financial fraud caused widespread market panic, which spread to CAR Inc., which belongs to the "Shenzhou Family". Affected by the crisis of investor confidence, CAR Inc.’s share price plummeted by 17.11% on April 8th. The market’s doubts about CAR Inc. focus on the expansion model similar to that of Ruixing, the authenticity of financial data and the joint liability of the major shareholder Lu Zhengyao. At the same time, international rating agencies Standard & Poor’s and Moody’s quickly downgraded CAR Inc.’s credit rating, which further aggravated investors’ panic. This incident shows that in the capital market, the financial transparency and governance structure of enterprises are very important. Once the trust crisis breaks out, it will not only increase the cost of information verification, but also trigger a series of chain reactions such as stock price crash, financing difficulties and credit rating downgrade.

Third, the impact of public opinion risk on different financing channels

1. Bond market

In the bond market, the impact of public opinion risk on credit bonds is particularly significant. For bond investors, the credit status of enterprises is one of the key factors in their decision-making. Negative public opinion events may cause investors to worry about the solvency of enterprises, which in turn will lead to the decline of bond prices and the expansion of credit spreads. For example, after the public opinion of financial fraud or poor management of some enterprises spreads, the credit rating of their bonds may be lowered, which will not only increase the financing cost of enterprises, but also make it more difficult to issue bonds. In addition, public opinion events may also trigger a chain reaction in the bond market, affecting the performance of credit bonds in the whole industry, and even impacting the stability of the bond market.

2. Equity market

In the equity market, public opinion risk will also have a significant impact on the stock price and equity financing cost of enterprises. Investors’ confidence in the enterprise is an important support for the stock price, and negative public opinion may weaken investors’ confidence and lead to a decline in the stock price. At the same time, the cost of equity financing will also rise due to the reassessment of corporate risks by the market. For example, when an enterprise faces public opinion events such as product quality problems or management scandals, investors may demand higher rate of return to compensate for risks, which will directly lead to an increase in the cost of equity financing. In addition, public opinion events may also affect the refinancing ability of enterprises, and may even cause enterprises to lose financing opportunities in the capital market.

3. Bank credit market

Bank credit market is one of the important financing channels for enterprises, and public opinion risk will also have an impact on bank credit. When deciding whether to provide loans to enterprises, banks will comprehensively consider the credit status, operating conditions and market reputation of enterprises. Negative public opinion events may make banks doubt the credit status of enterprises, thus raising the loan interest rate, increasing the collateral requirements or shortening the loan period. For example, when a company has a major negative public opinion, the bank may reassess the loan risk of the company and adopt a more cautious credit policy. This will not only increase the financing cost of enterprises, but also limit the liquidity of enterprises and affect the normal operation of enterprises.

Fourth, the relationship between public opinion risk and corporate governance structure

1. The role of the board of directors

The board of directors of enterprises plays a key role in dealing with the risk of public opinion. An effective board of directors can find and deal with public opinion risks in time and protect the interests and reputation of enterprises. For example, the board of directors can strengthen the supervision of enterprise operation and management by establishing a sound internal supervision mechanism, and discover potential public opinion risk factors in time. In addition, the board of directors can also communicate with investors, the media and the public to convey the positive information of the enterprise and alleviate the impact of the public opinion crisis on the enterprise.

2. Responsibility of management

Management also bears an important responsibility in public opinion risk management. The management needs to report the operating conditions and potential risks of the enterprise to the board of directors in time to ensure that the board of directors can fully understand the public opinion risk of the enterprise. At the same time, the management also needs to formulate and implement effective public opinion management strategies, strengthen the management and control of internal information of enterprises, and prevent the leakage of negative information. In addition, the management also needs to maintain good communication with external stakeholders, respond to market concerns in a timely manner, and maintain the good image of the enterprise. For example, when a public opinion crisis occurs, the management can clarify the truth by releasing accurate information in time, stabilize market expectations, and reduce the impact of public opinion risks on enterprises.

3. The role of internal audit

Internal audit also plays an important role in public opinion risk management. Internal audit can find out the potential risk factors of public opinion through auditing the internal financial and operational activities of the enterprise and report to the management and the board of directors in time. For example, internal audit can audit the authenticity, completeness and accuracy of enterprise financial statements to prevent negative public opinion events such as financial fraud. At the same time, internal audit can also evaluate the effectiveness of the internal control system of enterprises, put forward suggestions for improvement, and enhance the ability of enterprises to resist the risk of public opinion. In addition, internal audit can also participate in the formulation and implementation of enterprise crisis response plans to ensure that enterprises can quickly take effective response measures when public opinion crisis occurs.

V. Interaction between public opinion risk and macroeconomic environment

1. The impact of the economic cycle

The economic cycle has an important influence on the formation and spread of public opinion risk. In the period of economic prosperity, enterprises are in good operating condition, market confidence is high, and the risk of public opinion is relatively low. However, during the economic recession, enterprises are faced with great operating pressure and are prone to various problems, such as financial difficulties and layoffs, which may lead to negative public opinion. At the same time, during the economic recession, some enterprises suffered losses or closed down due to poor management. These negative events caused public concern about the operating conditions of enterprises in the same industry through media reports and network communication, which further aggravated the public opinion risk of the remaining enterprises in the industry. In addition, the change of economic cycle will also affect investors’ risk preference and market confidence, and then affect the impact of public opinion risk on corporate financing costs.

2. The impact of the policy environment

The policy environment also has an important impact on the risk of public opinion. The government’s policy adjustment and regulatory measures may lead to the public opinion risk of enterprises. For example, the strengthening of the government’s environmental protection policy for enterprises may make some highly polluting enterprises face greater operational pressure, which may lead to negative public opinion.

3. The influence of market confidence

Market confidence plays a key role in the interaction between public opinion risk and macroeconomic environment. When the market confidence is insufficient, negative public opinion events may be amplified, which will have a greater impact on the financing cost and market performance of enterprises. For example, in the period of economic instability or market volatility, investors’ confidence in enterprises is relatively fragile, and any negative public opinion may lead to panic selling or financing difficulties. On the contrary, in the case of sufficient market confidence, even if there are some negative public opinions, investors may treat them more rationally and will not easily overreact to enterprises. Therefore, enterprises need to pay close attention to the changes of market confidence and adopt corresponding strategies in public opinion management to reduce the impact of public opinion risk on enterprises.

Sixth, the industry differences of public opinion risk

1. Public opinion sensitivity of different industries

There are significant differences in the sensitivity of different industries to public opinion risk. Some industries are more sensitive to the risk of public opinion because of their business nature and high social concern. For example, in the financial industry, food industry and medical industry, once negative public opinion appears in enterprises in these industries, it may quickly arouse public concern and doubt, which will have a significant impact on the financing cost and market performance of enterprises. Taking the financial industry as an example, the credibility of banks and financial institutions is the key to their survival and development. Any public opinion about financial fraud, poor risk management or poor management may trigger market panic, leading to a sharp drop in stock prices and a sharp rise in financing costs.

2. Transmission mechanism of industry public opinion risk

The risk transmission mechanism of public opinion in different industries is also different. In some industries that are highly dependent on market confidence and public image, such as tourism, hotels and aviation, negative public opinion may directly affect the income and cash flow of enterprises through changes in consumer behavior. For example, when there are security problems or negative public opinions in tourist destinations, consumers may choose other destinations, which will lead to a sharp drop in the income of local tourism enterprises, thus affecting their financing ability and financing cost. In some technology-intensive industries, such as science and technology and Internet industry, public opinion risk may be transmitted by affecting the technological innovation ability and market competitiveness of enterprises. For example, when technology leakage or public opinion of product quality problems occur in technology enterprises, it may lead to their disadvantage in market competition, and then affect their financing environment and financing cost.

VII. Future development trend of public opinion risk

1. The challenge of public opinion risk in the digital age

With the rapid development of digital technology, the spread speed and influence of public opinion risk will be further enhanced. The popularity of social media, network platform and mobile Internet makes information spread more rapidly and widely, and public opinion events can trigger global attention and discussion in a short time. For example, some companies’ inappropriate comments or behaviors posted on social media may quickly trigger public doubts and criticisms, which in turn will affect the financing costs and market performance of enterprises. Therefore, in the digital age, enterprises need to pay more attention to public opinion management, establish a sound public opinion monitoring and early warning mechanism, and timely discover and deal with public opinion risks.

2. The combination of artificial intelligence and public opinion management

The development of artificial intelligence technology provides new means and methods for public opinion management. Through artificial intelligence technology, enterprises can realize real-time monitoring and analysis of massive public opinion data and quickly identify potential public opinion risks. For example, using natural language processing technology, enterprises can analyze the emotion and identify the theme of text data on social media, and find the signs of negative public opinion in time. At the same time, artificial intelligence technology can also help enterprises formulate more accurate public opinion coping strategies, analyze and predict historical public opinion events through machine learning algorithms, and provide decision support for enterprises. For example, some enterprises have developed a public opinion early warning model by using artificial intelligence technology, which can predict the occurrence probability and influence degree of public opinion risk in advance, provide early warning information for enterprises, and help enterprises prepare in advance.

3. Long-term management of public opinion risk

The management of public opinion risk needs to pay attention not only to short-term crisis response, but also to long-term reputation building and risk prevention. Enterprises need to establish a good brand image and social image through continuous reputation management, and enhance public trust and recognition of enterprises. For example, enterprises can enhance their social reputation and public image by actively fulfilling their social responsibilities and strengthening communication and cooperation with stakeholders. At the same time, enterprises need to establish a sound risk management system, incorporate public opinion risk into the overall risk management framework of enterprises, and reduce the impact of public opinion risk on enterprises through institutionalized, standardized and normalized management measures. For example, enterprises can conduct public opinion risk assessment regularly, formulate public opinion management strategies and plans, and establish public opinion response teams and working mechanisms to ensure that they can respond quickly and effectively when public opinion crises occur.

In a word, public opinion risk has become one of the important factors affecting the financing cost of enterprises. Through in-depth analysis of the pricing mechanism, transmission mechanism and management strategy of public opinion risk, enterprises can better cope with public opinion crisis, reduce financing costs and enhance their market competitiveness. In the digital age, the spread speed and influence of public opinion risk will be further enhanced. Enterprises need to pay more attention to public opinion management, establish a sound public opinion early warning and response mechanism, and use new technical means such as artificial intelligence to improve the efficiency and effectiveness of public opinion management. At the same time, enterprises need to pay attention to long-term reputation building and risk prevention, and enhance their anti-risk ability and market competitiveness through continuous efforts. Future research needs to further quantify the elasticity coefficient of public opinion risk in different industries, provide more scientific theoretical support for accurate risk management of enterprises, and promote the scientific, standardized and professional development of public opinion management of enterprises.

Depp joined Hollow Man.

　 　 1905 movie network news Universal Picture’s "Monster Universe" plan is moving forward in an orderly way. A few days ago, the remake of Hollow Man attracted a famous actor to join us. It is reported that Johnny Depp will definitely join the film and play the role of invisible man in the film. In the original film, the invisible man became a killer after being invisible, and there were killers in Depp’s previous screen roles, so this role is more suitable for Depp to interpret.

　 　 The original Hollow Man, filmed in 1933, tells the story of a talented scientist who invented an invisibility reagent that can make people invisible after drinking. Although the effect of the reagent is obvious, unfortunately, the side effects make the scientist become eccentric, and gradually, he becomes an invisible killer. The film depicts the alienation of science and technology to human beings. Although it is exaggerated, the scenes of a large number of invisible people killing people in the film are still chilling. The film has been put on the screen five times. The famous David .S. Goyer once filmed a version in 2007.

The 1933 edition of Invisible Man

　 　 As early as last year, Universal decided to build a "monster universe", hoping to copy the successful experience and bring the famous monsters in the film history such as Dracula, Frankenstein, Frankenstein’s bride, werewolf, invisible man, mummy, and Black Lake Fishman to the big screen. Judging from the progress of the current exposure, the list signed by Universal is big: Tom Cruise just confirmed to join us not long ago, and now Hollow Man has invited Depp to join us. Just from the stunt, this "monster universe" can be described as huge.

　 　 Universal Picture’s Hollow Man will be written by ed solomon, a screenwriter, and the director candidate and release time have not been decided.

Conor McGregor

　　　　 On August 28th, Beijing time, according to foreign media reports, Conor McGregor, a mixed martial arts athlete, joined the action thriller "Veyron kill array" and made his debut, playing an original role other than himself.

　　The film, starring Jake Gyllenhaal, directed by doug liman and produced by Amazon, will be streamed online. Ji Runhall plays a former UFC fighter who works as a bodyguard in a disorganized hotel in the Florida keys, but soon discovers that everything is not what it seems in this tropical paradise.

　　Billy magnussen, Daniela Melchior, Jimsola Akumello, Lucas Gage, Anthony Bagarozzi (The Tear-Resistant Detective) and Chuck Mundre are also the screenwriters, and filming will begin in the Dominican Republic later this month.

　　In 1989, the original film was directed by Rowdy Herrington and starred by Patrick Swayze, kelly lynch, sam elliott and Ben Gazzara. Dalton, an outstanding and popular bodyguard, moved to a small town in Missouri to help clean up a disorderly bar, exposing the corrupt behavior of local bully businessmen in the process.

> > > 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.)

● DQ200(5 you don’t know (5)
-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.

　　On October 18th, in Moscow, the Russian capital, Russian President Vladimir Putin listened to people’s questions during the program. Xinhua news agency

　　　　In recent weeks, there has been a wave of support for Putin to stay as president after 2008 throughout Russia. For a time, people gathered to beg, officials expressed their hopes, and political parties made suggestions, demanding that Putin stay in office. The Russian "News Times" article said with emotion: "Before, such a request was not unheard of, but it did not have the current scale and popularity. The number of people involved in this activity and the wide geographical area are inevitably suspicious: is this premeditated? " After the Russian presidential election next year, there have been many versions of predictions on what role Putin will continue to play in the political arena, what influence he will play, and what scope he will play. Putin himself has repeatedly made it clear that he will not seek re-election. Can Putin be retained by the wave of retention that is now higher than the wave? What is behind it, and the parties have given different interpretations.

　　The number of people involved and the geographical scope are unprecedented.

　　　　According to the Russian "Viewpoint" reported on November 11th, a youth organization in Moscow held a series of activities such as assembly and party on November 10th, and they planned to collect millions of signatures within one month to support Putin’s staying in office. Their slogan is: "Support Putin! Support a unified Russia! " Its member Arthur? Savilov said that they would try their best to find a good way for Putin to bypass the constitutional provisions. "We will do our best to make President Putin change his mind and stay in office.". When asked about the limitations of the Constitution, Savilov replied, "What is the Constitution? The constitution was formulated by the people. This constitution was adopted in 1993. Now how many years have passed and the country’s situation has undergone earth-shaking changes. "

　　　　Russia’s Kommersant published an article entitled "Supporting Putin Movement to Become an All-Russian Movement" on November 9. The article said that in recent days, the All-Russian Social Movement "Supporting Putin" organization planned to hold a meeting and asked Putin to stay in office. On November 15, there are still some areas in Russia that are ready to hold a rally in support of Putin. It is also reported that from October 23 to 30, similar gatherings were held in major cities such as Volgograd, Grozny, Pskov, Novosibirsk and Magadan. In the Ural Federal District, within one day, three local councils passed an appeal for Putin to remain in power.

　　　　Many Russian officials have also joined in retaining Putin. Chechen President Kadyrov said, "If Russia is to maintain its current stable development and become a world power again, Putin should continue to be the president. Since the presidents of Kazakhstan, Turkmenistan and other countries can serve for life, why not Russia? " Kadyrov made no secret of his admiration for Putin. He said, "Putin is a hero who saved Chechnya and gave the Chechen people a second life. He also saved Russia. He is a gift from God to Russia. " Mironov, chairman of the Russian Federation Council (upper house), publicly stated that "Russian President Vladimir Putin should find a way to keep him as president after the expiration of his presidency in 2008, because the Russian people want him to stay". According to the latest poll released by the Levada Polling Center, 53% of the respondents said that they "welcome or welcome" Putin for another term, up by 12 percentage points from 2005. The Russian Constitution stipulates that "the same person shall not serve as President of the Russian Federation for more than two consecutive times". According to the current constitution, Putin will officially leave the presidency in May 2008.

　　Whether to stay in office involves the interests of all parties.

　　　　Putin’s supporters stressed that under Putin’s leadership, Russia ended the chaotic situation since the disintegration of the Soviet Union, achieved rapid economic growth and restored its international prestige. They insisted that the reason why they stayed was their heartfelt love for Putin and for the future of Russia. Observers have interpreted this wave from different angles. The British "Guardian" analyzed that many political advisers of Putin were extremely worried that if the "boss (Putin)" finally left the Kremlin, they would lose power, so they tried their best to encourage the people to launch a campaign to retain Putin.

　　　　Others believe that this move is an effort by the "United Russia" party to enhance its influence before the election of the Russian State Duma (lower house) in December. Last month, Putin made it clear that he would participate in parliamentary elections as the candidate of Russia’s largest party. There are also some opponents who criticize that Putin has once again set off a cult of personality. Opposition leader nemtsov said: "I like the saying’ Russia without Putin’, although it is unrealistic."

　　　　Vinogradov, director of the Russian Center for Research on Political Trends, believes that the holding of "spontaneous" gatherings and the appearance of local council petitions do have traces of meticulous organization. He said: "This is to strengthen Putin’s position after the election of the Russian State Duma (lower house). But at present, it seems unlikely to continue for the third term. " Konovalov, director of the Russian Institute for Strategic Evaluation, said: "This should be regarded as the pressure of Russian bureaucratic groups on Putin. I am convinced that Putin actually wants to leave. Indeed, he was confused about his future plans, first talking about the post of prime minister, and then withdrawing his remarks. He has no definite plan yet. The pressure on Putin will continue in the future, because whether he stays in office involves the personal interests of many political elites. " Ding Peihua, director of the Eurasian Development Office of the Eurasian Institute of Shanghai Academy of Social Sciences, said in an interview with the Global Times that Putin has always had a high popularity among the Russian people, and the recent wave of people retaining Putin is only one of the manifestations. He believes that it is inevitable for the Russian people to support Putin. The support of the masses for Putin should still be within a reasonable range.

　　Putin will become the spiritual leader of Russia?

　　　　The Star newspaper in Toronto, Canada, reported on November 12th that the whole country in Russia is now more concerned about how to let Putin stay, but so far, Putin has only said a few words about whether to stay or not, which also makes Putin’s whereabouts after 2008 become a suspense of the whole world. On October 26th, when Putin attended the Russia-EU summit in Portugal, he said that he would not amend the constitution for the sake of three presidents and would not weaken the power of the president, and denied that he might become the prime minister after leaving office.

　　　　Russia’s new network published an article entitled "Putin will become the spiritual leader of Russia" on November 9, and made an in-depth analysis of Putin’s whereabouts. The article said, "Putin has been re-elected as president for two times, and it is very difficult to surpass himself. To be re-elected as the third president in violation of the constitution is to openly regard the constitution as a dummy, which is contrary to Putin’s political philosophy; It is Putin’s fault to advance the presidential election or to be the first prime minister and then the president. Being the prime minister, overhead the president, and replacing the presidential system with the government-parliament power structure is actually a disguised coup, and Putin’s painstaking plan of governing the country will be destroyed, so the above plan should not be considered by Putin. " The article analyzes that if you want to know where Putin will go after leaving office, you must first know what Putin wants to do. Now it can be clearly said that Putin’s minimum program is to ensure the continuity of current policies, that is, to ensure the long-term implementation, implementation and implementation of Putin’s concept of governing the country; The highest program is to realize the comprehensive rejuvenation of Russia.

　　　　The article believes that with Putin’s consistent style, he will not seek the highest administrative power again (even if he has this idea, he must abide by the Constitution and go out again after 2012). He wants to be the de facto spiritual leader of Russia. In this way, firstly, Putin’s existence itself is a constraint on "secular" administrative and legislative power, because "Putin’s concept of governing the country" is the ruling basis of his successors; Second, Putin will have the absolute right to interpret this concept of governing the country.

　　　　Putin’s latest statement seems to prove once again his idea of not seeking re-election, but ensuring influence. According to Agence France-Presse, Putin said on November 13 that if the "United Russia" party wins the election on December 2, it will have a moral reason to continue to maintain its influence on this country. The report quoted Putin as saying: "If people vote for the’ United Russia’ party, it means that they trust me, then I will also have the moral right and have the responsibility to push the Duma and the cabinet to complete our established tasks." The report mentioned that Putin repeatedly hinted that he would continue to retain an important role in politics, but he refused to explain how to retain a role. Putin said: "So far, I won’t give a clear answer, but all kinds of possibilities exist."

　　Is the next president strong or weak?

　　　　Since Putin will not stay in office, who will take Putin’s class has become the most concerned topic for Russians. In the first half of this year, there was a rumor in Russia that Putin would appoint a new prime minister this autumn, and this new prime minister would definitely be Putin’s "successor". However, when people found that the new prime minister turned out to be the previously unknown Zubcov, rather than Ivanov or Medvedev, as public opinion had always suspected, they were at a loss again. On November 6th, a poll conducted by the Russian Social Research Center showed that more than half of Russians thought that Putin had decided who would succeed him, and 32% of the respondents thought that Zubcov was the most likely to succeed him as president. However, the answer to this world-wide riddle has not yet been revealed, and various speculations are still going on.

　　　　Some analysts believe that with the approach of the Russian State Duma and presidential elections, Putin has indeed begun to lay out plans for 2008, and the "multi-power center" is likely to be the new power structure left by Putin for Russia. In other words, the future president of Russia may not be as strong as Putin, but will be replaced by a "team." This "team" will achieve the stability of the "multi-power center" through checks and balances among the president, the prime minister, the upper house and the lower house, so as to maintain the stability of the "Putin line."

　　　　In response, Medvedev, the first deputy prime minister of the Russian government, said in a meeting with students from Kazan State University on November 12 that "only when the president has great power can a country like Russia stand among the nations of the world". According to media analysis, Medvedev’s words may mean that the next president will still be a strong president. The political situation in Russia is always so unpredictable. Russian poet Chutchev once described Russia like this: "Russia cannot be understood by reason, nor can it be measured by general standards. There are special things in it." Nevertheless, it is generally believed that no matter how the political situation in Russia changes, the "Putin Line" has become an established national policy for Russia’s future development.

With the increasingly fierce competition in the automobile market, there is a cruel elimination match between automobile enterprises, some of which have been forced to withdraw from the stage, while others are being pushed out of sight by the "big waves".

For example, Roewe, a brand that was once popular in the market with its star model RX5. In 2018, with the help of Roewe RX5, Roewe went to the "highlight" moment with a performance of over 470,000 vehicles.

However, with the rise of new forces and the efforts of various traditional car companies in technology and new products, the labels and selling points of Roewe RX5 are no longer competitive. Since 2021, the sales volume of Roewe RX5 has entered a state of sharp decline. In 2022, the sales volume continued to decline, with a direct drop to "freezing point" in April, with a monthly sales volume of only 1,990 vehicles.

The sales volume of Roewe RX5 has shrunk, which directly affects the overall performance of the brand. In 2021, the sales volume of Roewe was only 348,400, and in 2022 it dropped to 260,000. You know, in 2017, the sales volume of Roewe RX5 alone was 237,000, which shows how much it was affected.

To sum up the decline of Roewe, it is precisely because it relies too much on the sales support of Roewe RX5, and the brand performance is in trouble because the number of vehicles is too single. The decline in sales of Roewe RX5 is due to the "short board" of product strength, which has no advantage compared with the current new energy vehicles and the market competitiveness is greatly reduced.

Fortunately, in the face of successive declines, Roewe also took out its own attitude step by step, stepped up the push of new cars, and strived to catch up.

The latest news shows that Roewe will launch a new car, Roewe D7, this month. The new car is aimed at medium and large cars, and it will launch a DMH hybrid version and an EV electric version respectively. At the same time, the new car will integrate scientific and technological equipment such as Yunsu cockpit and zebra intelligent driving machine system.

From the appearance, the front face of the new car adopts a brand-new inductive design language, which is different from the design of the existing Roewe series products and is more recognizable as a whole. Specifically, Roewe D7 EV and DMH adopt different shapes, and D7 EV adopts the design of closed front face and split headlights. The D7 DMH adopts integrated headlights, and the front air intake grille adopts the extension design elements of left-right expansion and up-and-down support, which makes the vehicle’s vision more spacious.

From the side of the car body, this car is equipped with hidden door handles and 18-inch wheels with low wind resistance, which is more scientific and technological as a whole. In terms of the rear end, the tail shape is round and generous, full and full of tension.

The taillights are slender in shape, with the duckling tail design with the edge of the trunk slightly upturned, which is full of movement. In terms of body size, the length, width and height of the new car are 4890/1872/1510mm and the wheelbase is 2810mm respectively.

In terms of interiors, the two cars are consistent, equipped with an integrated large screen and made of a lot of suede. It is worth mentioning that the seat is decorated with diamond-shaped elements, which increases the sense of advanced vehicle.

In terms of power, Roewe D7 pure electric version was born in SAIC Nebula pure electric platform, which will provide two new Rubik’s cube batteries, corresponding to CLTC comprehensive cruising range of 510km and 610km respectively. In terms of power, the new car will be a VGA six-in-one motor and a permanent magnet synchronous motor with a maximum power of 155kW.

The DMH hybrid version is equipped with a hybrid engine with a thermal efficiency greater than 43% and a fuel consumption of 4.3L/100km. Under CLTC condition, its pure electric cruising range is 125km and its comprehensive cruising range is 1400km.

Write it at the end

As a medium-sized and large-sized car, Roewe D7 combines advanced technology design and diverse power options, which is very in line with the current mainstream. After the new car goes on the market, it will compete with BYD Seal and Deep Blue SL03. It is said that the price will start from 130,000, which is still attractive to consumers.
