Suspected of hypertrophic cardiomyopathy？ The eight major tests are coming.

▼ The author of this article ▼

Hypertrophic cardiomyopathy (HCM) is a myocardial disease with unknown causes, characterized by asymmetric myocardial hypertrophy, which usually means that the thickness of ventricular septum or left ventricular wall measured by echocardiography is ≥15mm, or the thickness of patients with a clear family history is ≥13mm, the ventricular cavity becomes smaller, the left ventricular blood filling is blocked, and the left ventricular diastolic compliance decreases. It is necessary to exclude the thickening of left ventricular wall caused by increased load such as hypertension, aortic stenosis and congenital aortic subvalvular diaphragm.

How to diagnose hypertrophic cardiomyopathy?

01exertional dyspnea

The most common symptom, about 90% or more will show this symptom.

02chest pain

Many patients will show fatigue chest pain, or atypical pain may continue to occur at rest or after meals, but coronary angiography is normal.

03Syncope or threatened syncope

About 15%-25% of patients have had at least one syncope or threatened syncope, which is usually seen during activity.

04Other symptoms

Dizziness, fatigue, palpitation, etc., some patients are at high risk of sudden death, and some patients have symptoms of heart failure in the late stage.

05pathological/bodily sign

Patients with no or mild obstruction often have no obvious signs, but patients with left ventricular outflow tract obstruction often have heart murmurs, especially after the first heart sound, which are obviously increasing and decreasing, especially between the apex of the heart and the left edge of the sternum.

Some tests are needed to assist the diagnosis in clinic.

01x-ray examination

X-ray examination has no obvious characteristics. The size of the heart may be normal, or the left atrium and left ventricle may be enlarged. The size of the heart is directly proportional to the pressure gradient between the heart and the outflow tract of the left ventricle. The greater the pressure gradient, the larger the heart. Aorta does not widen, pulmonary artery segment does not protrude obviously, pulmonary congestion is mostly light, and right ventricular enlargement may occur in the late stage.

02electrocardiogram

Because of cardiac ischemia, abnormal myocardial repolarization, left ventricular or biventricular hypertrophy and ST-T changes are common, atrioventricular block and left bundle branch block are also common, and sometimes deep and inverted T wave or abnormal Q wave can be seen, this disease often has various types of arrhythmia.

03ultrasonic cardiogram

It is of great significance for the diagnosis of HCM. The main performances are:

① Abnormal thickening of ventricular septum, and the thickness of ventricular septum at the end of diastole is > 15 mm..

② The motion amplitude of interventricular septum decreased obviously, generally ≤ 5 mm..

③ The ratio of ventricular septal thickness to left ventricular posterior wall thickness can reach 1.5-2.5:1, and it is generally considered that the ratio > 1.5: 1 has diagnostic significance.

④ The left ventricular end systolic diameter is smaller than normal, and the blood flow velocity of left ventricular outflow tract is accelerated.

⑤ The distance between the interventricular septum and the anterior leaflet of mitral valve is often significantly reduced at the start of contraction.

⑥ The systolic phase of the anterior leaflet of mitral valve moves forward, approaches the interventricular septum, and ends before the second heart sound.

⑦ Aorta closed in the middle systole.

04dynamic electrocardiogram

All patients have perfect 24-hour ECG monitoring, in order to evaluate whether there is ventricular arrhythmia and judge the cause of palpitation or syncope.

05Cardiac magnetic resonance

High sensitivity, but high cost. Myocardial fibrosis can also be found.

06Coronary angiography

Coronary angiography should be evaluated if the patient has angina pectoris or persistent ventricular arrhythmia.

07Cardiac catheterization

Left ventricular outflow tract obstruction is suspected, but the clinical manifestations and imaging examination are different; It needs to be differentiated from constrictive pericarditis; Preoperative evaluation of heart transplant patients.

08Gene detection

Most patients often have a family history and have genetic mutations.

Complications of hypertrophic cardiomyopathy

01arrhythmia

Ventricular arrhythmia and atrial fibrillation are common, and in severe cases, there are ventricular tachycardia, ventricular fibrillation and cardiac arrest, which can cause sudden cardiac death in severe cases.

02arterial embolism

The common site is the left atrial appendage, and it can also form thrombus in the left ventricle, which can cause arterial embolism after the thrombus falls off.

03cardiac failure

Due to myocardial hypertrophy, the compliance of ventricular relaxation is reduced, which can cause left ventricular diastolic dysfunction and increase left ventricular end diastolic pressure and left atrial pressure in the early stage. With the progress of the disease, it may be accompanied by left ventricular dilatation and contraction dysfunction, resulting in severe heart failure symptoms.

Keep a promise in your life and promise your motherland with your own body.

　　CCTV News: He was once a world-famous scientific research star, but he disappeared at the peak. He left his hometown, remained anonymous, and even his family didn’t know what he was doing … … He used his whole life to fulfill his promise: I would like to promise my country.

　　He is Wang Ganchang, the founder of China’s nuclear science and winner of the "Two Bombs and One Satellite" Meritorious Medal. On December 10th, 1998, Wang Ganchang died at the age of 91.

　　Recall a generation of meritorious deeds.

　　Life of Wang Ganchang

　　Why should I keep doing what others can do? But there is one job I won’t quit, and that is scientific research.

　　— — Wang Ganchang

Wang Ganchang (May 28, 1907.5.28— 1998.12.10）

　　Wang Ganchang was born in Changshu, Jiangsu Province in 1907. I went to a private school first and went to Shanghai at the age of 13 to attend Pudong Middle School.

　　In 1925, Wang Ganchang was admitted to Tsinghua University, where he stayed as a teaching assistant in 1929. In 1930, Wang Ganchang took the official fee from Jiangsu Province to study abroad, and went to the William Royal Institute of Chemistry at the University of Berlin, Germany, where she studied under the famous female nuclear physicist L Maitenaz. In 1934, she received her doctorate and returned to China to teach.

　　In 1956, Wang Ganchang went to Dubna United Nuclear Research Institute of the Soviet Union as a researcher and was elected as the deputy director. The physics team led by him discovered the anti-Sigma negative hyperon for the first time, which caused a sensation in international academic circles.

△ Wang Ganchang when he was young

　　In December 1960, Wang Ganchang returned from the Soviet Union and was ordered to secretly participate in the development of atomic bombs. In 1962, he basically mastered the means and experimental technology of atomic bomb implosion.

　　In December 1964, Wang Ganchang independently put forward the proposal of laser-driven nuclear fusion, and the research of laser nuclear fusion in China started.

　　In 1984, Wang Ganchang accepted the honorary certificate awarded by the University of Berlin, which was specially set up for scientists who were still working in the front line of scientific research 50 years after receiving their doctorate. People called them "Dr. Jin".

　　At 21: 48 on December 10th, 1998, Wang Ganchang died of illness in Beijing at the age of 91.

　　In 1999, the Central Committee of the Communist Party of China, the State Council and the Central Military Commission awarded him "Two Bombs and One Satellite Meritorious Medal".

　　I missed the Nobel Prize twice.

　　When he was a graduate student at the University of Berlin, Wang Ganchang, who was only 23 years old, had a chance to embrace the Nobel Prize. At that time, Wang Ganchang proposed to his teacher, Maitney, to experiment with a penetrating ray in a cloud room. Maitney is a prestigious nuclear physicist, but this time she underestimated the creativity of China’s young man. She rejected Wang Ganchang’s application twice. Two years later, chadwick, a British physicist, adopted the experimental method proposed by Wang Ganchang and discovered neutrons, thus winning the Nobel Prize in Physics.

△ Professor Metterne is known as "Madame Curie of Germany"

　　In 1941, Wang Ganchang published a short article "Suggestions on Detecting Neutrinos", and American physicist Allen carried out experiments according to the suggestions in Wang Ganchang’s paper, and nearly completed the verification of neutrinos. At this time, in Wang Ganchang in the northwest, Sun Hao, a teaching assistant, and Xu Liangying, a student, were asked to carry on the experiment, but unfortunately they didn’t follow Wang Ganchang’s design. In 1995, American scientist F. reines won the Nobel Prize in Physics for his confirmation of the existence of neutrinos. When the news came, 88-year-old Wang Ganchang said simply: The honor should go to the scientist who made the final result.

　　have [with] pupils everywhere; have [with] students all over the country [world]

　　Wang Ganchang has been a university professor for 20 years, and he is full of peaches and plums. Li Zhengdao, a Chinese scientist, is his disciple. In the field of national defense research, he taught by example, and Zhou Guangzhao, Deng Jiaxian, Yu Min, Chen Nengkuan, Cheng Kaijia, Du Xiangwan, Hu Renyu, Hu Side, Tang Xiaowei, Lv Min, Ding Dazhao, Wang Naiyan and He Xiantu all received direct guidance from Wang Ganchang.

My father

Information provided/Wang Zunming (daughter of Wang Ganchang)

　　Father is an ordinary and simple person, and material enjoyment is out of place for him.

　　In War of Resistance against Japanese Aggression’s time, life was extremely hard. Seven members of my family moved to Guizhou with Zhejiang University, relying on my father’s meager salary to make a living. At that time, my father got tuberculosis, and the situation was very difficult. At this time, in order to support War of Resistance against Japanese Aggression, my father donated all the gold and silver jewelry he had left when he got married to the country. Later, a sheep was raised at home, and it was supplemented with goat’s milk to survive the hard times.

　　In 1947, my father won the Fan Xudong Prize, and he distributed the $1,000 he got to teachers, colleagues and students who were in more financial difficulties, but he didn’t give a penny to the families who were still in financial difficulties.

　　In 1960, when I was in college, I suffered from malnutrition and edema. In this year, my father was ordered to return to China from the Soviet Union. He gave all his accumulated salary of 140,000 rubles (old coins) to Liu Xiao, the ambassador to the Soviet Union, hoping to contribute to the country’s difficulties. Father didn’t bring any material improvement to his family and children after he returned to China.

△ The left one is Wang Ganchang

　　During the development of the two bombs, my father traveled in Qinghai Plateau and Gobi Desert in Xinjiang for many years and rarely returned to Beijing. According to state regulations, you can enjoy subsidies and special care in plateau areas. But not only does he not want subsidies and care, but every time he returns to Beijing from the nuclear base, he pays for his own travel. When the secretary wanted to take the ticket for reimbursement, he said that the money was enough, so why report it? Later, the secretary reimbursed him behind his back, and he was still very angry when he found out.

　　In 1982, he donated all the RMB 3,000 prize money won by the National Natural Science First Prize to the Atomic Energy Institute. In his letter to the Party Committee of the Institute, he wrote, "I voluntarily donate all the prize money to the primary and secondary schools of the Atomic Energy Institute, hoping that the dolls in the motherland can grow sturdily, thus reducing some worries for their fathers and doing more work for the atomic energy industry." The prize money established the Wang Ganchang Scholarship.

　　In 1986, my father donated 40,000 yuan, and the Institute of Atomic Energy established the "Wang Ganchang Basic Education Award Foundation". From 1986 to 1999, 616 people have won this prize, and many of them have achieved excellent results.

　　After my father’s death, we donated 500,000 yuan to set up the "Wang Ganchang Prize in Physics" to reward researchers who have made outstanding contributions in the fields of inertial confinement fusion and particle physics. At the same time, he donated 100,000 yuan to his hometown, Changshu, to develop local cultural and educational undertakings.

"The" Wang Laotou "who has been lurking in Treasure Beach for 17 years"

This article was originally published in cstnet, but it has been revised.

　　In 1958, an army had just returned triumphantly from the Korean battlefield. Instead of disarming and returning to the fields, they went straight to the depths of the desert, and they received only one order — — Don’t ask what you are doing, and don’t ask where you are going.

　　Two years later, Wang Ganchang, a world-renowned China scientist with the greatest potential to win the Nobel Prize, suddenly disappeared. At the same time, another man named "Jing Wang" appeared in the northwest of China.

　　They, for the common mission.

△ Wang Ganchang

　　From "Wang Ganchang" to "Jing Wang", he said: I would like to make my country.

　　In 1960, the Soviet Union withdrew all its experts in China and unilaterally tore up more than 200 contracts, leaving behind a large number of half-finished projects. At this time, Wang Ganchang was studying with atoms and experts from all over the world using the most powerful accelerator in Dubna, the Soviet Union. Wang Ganchang and his team discovered the world’s first anti-Sigma negative hyperon.This discovery is enough to prove that it was only a matter of time before Wang Ganchang wanted to win the Nobel Prize.

　　However, at this moment, a phone call from China changed Wang Ganchang’s fate.

　　On April 3, 1961, Wang Ganchang, who had just returned to China, received a notice from the Second Ministry of Machinery Industry: Minister Liu Jie asked him to meet immediately. In the office, Liu Jie and Qian Sanqiang met with Wang Ganchang, and conveyed to him the important decision of the Central Committee: I hope he will participate in China’s nuclear weapons research, and ask him to give up his research direction and do applied research that he is unfamiliar with but urgently needed by the country. Finally, I asked him if he would like to change his name. Wang Ganchang without hesitation, immediately wrote down the word "Jing Wang", and hit the floor said:"I would like to make a country."

　　At that time, Wang Ganchang was in his fifties.

　　The "No.17" construction site at the foot of Yanshan Mountain is the first movement of China’s nuclear weapons detonation experiment.

　　In this way, Wang Ganchang devoted himself to the development of nuclear weapons by leaving his hometown, hiding his name, keeping it absolutely secret and cutting off all relations with overseas countries.

　　The research work of the atomic bomb started from scratch. In order to train the team of detonation experiments, Wang Ganchang specially gave young people a week’s training course, from mathematics to physics to experimental analysis. After all the work was ready, a group of them came to No.17 construction site at the foot of the ancient Great Wall in Yanshan Mountains.

　　A bunker, several rows of simple barracks and more than a dozen military tents are the first atomic bomb detonation test site and component development base in China. Wang Ganchang and Chen Nengkuan led a young research team with an average age of only 20 years old here, and conducted detonation experiments again and again.

△ Wang Ganchang (first from the right) guides the work.

　　The living conditions on the construction site are very difficult, but what is even more difficult is the scientific research environment. The explosives and components used in the initial detonation experiment were all stirred by hand in tents with enamel pots and wooden sticks. It is very hard to stir explosives in the tent, because the tent is not well ventilated, and the whole tent is filled with explosive dust, and the strange and unpleasant smell rushes in, and the agitator has to stir quickly. Although the work is hard, the young boys are all full of energy. The harder the job, the more they strive to do it, and finally they simply take turns mixing. Wang Ganchang, who is in his fifties, is also struggling to do this job. Everyone looks distressed and pushes him outside the tent, but as long as no one pays attention, he will return to the tent.

　　As the leader in charge of the overall work of detonation experiment, Wang Ganchang should pay attention to all aspects of the experiment. From the development of explosives, the study of explosive molding, to the detonation physics experiment, and finally to the test work, he must personally guide. Wang Ganchang’s former research field was experimental physics, and he was not familiar with explosives, detonation and explosion mechanics, so he had to learn from scratch and give lectures at the 17th construction site. In the lecture, he often encounters problems, so he starts everyone to discuss together, and those who are able are teachers and those who will be teachers. On site 17, everyone works hard during the day and studies books at night. In this way, with everyone’s joint efforts, after repeated experimental improvements, the quality problem of explosives was finally solved.

△ Wang Ganchang (first from left)

　　With the success of the detonation experiment in No.17 construction site, China’s nuclear weapons test also started. Some people say that the rumble of guns at the foot of Yanshan Mountain is the first movement of China’s nuclear weapons detonation experiment.On the day he left the scene of the explosion, 55-year-old Wang Ganchang pulled out a few white hairs and left them in a crevice as a souvenir.Twenty years later, he won the first prize of the National Natural Science Award for the detonation experiment on the 17th construction site.

　　Into the northwest, hidden gold and silver beach, the secret years of 221 factory.

　　After March 1963, most researchers went to the Northwest Nuclear Test Base. Because of confidentiality requirements, Wang Ganchang told his wife, Wu Yueqin, that he would work in Xi ‘an for a period of time, and then he went to Treasure Beach in Qinghai.

　　Jinyintan is located in haiyan county, Qinghai Province, and the nuclear weapon research and development base in the center of Jinyintan grassland is called Factory 221. It is said that for the nuclear cause of the Republic, more than 1,700 herdsmen in Jinyintan grassland moved out and gave up their land for generations without compensation.

△ Qinghai Jinyintan

　　In Factory 221, Wang Ganchang still focuses on detonation experiment, that is, "cold experiment". The detonation experiment was carried out in several experimental bases far away from his residence, which was much larger than the No.17 construction site of that year. In order to keep abreast of the progress of the experiment, he shuttled between several experimental bases like a lantern. Every day, people can see Wang Ganchang wearing a uniform military coat and a pair of high boots, and rushing by in a jeep. At the base, the boys humorously called him "Wang Laotou".

　　At work, Wang Ganchang’s "stubbornness" is well known. Sometimes when something goes wrong at work, he will lose his temper loudly. Even Deng Jiaxian, an old scientist, wanted to hand in the derived data later because he was really too busy. When asking for instructions with this dean Wang, he was also uneasy. In his later years, Wang Ganchang wrote in his memoirs:"The task is very urgent. The development of the atomic bomb is a huge and complicated systematic project, and all links must be strictly controlled. After the theoretical scheme is determined, all aspects of the production experiment must meet the requirements of Premier Zhou Enlai ‘ Serious, thoughtful and meticulous, safe and reliable, foolproof ’ 。”

　　Nuclear weapons work is extremely confidential, so we can’t reveal any information to anyone, and there are special requirements for the whereabouts of the staff and who to meet. Once, Wang Ganchang had just returned to Beijing from the base, and before he could catch his breath, he received an order to return to the northwest base immediately, so he had to leave Beijing immediately. Later, he learned that Japanese scientists who came to Beijing wanted to meet Wang Ganchang, but his identity was unable to meet foreign guests, so Premier Zhou informed him to leave Beijing quickly and return to the base, and told foreign guests that Wang Ganchang was not in Beijing and could not make an appointment.

　　After the successful experiment of hydrogen bomb principle, Wang Ganchang only said meaningfully: "It’s not easy!"

　　At that time, the northwest nuclear test base had unimaginable conditions. Limited experimental conditions, limited equipment, it is under such conditions that our scientists have mastered the key technology of China’s first atomic bomb explosion. Wang Ganchang led his team, from the foot of the Great Wall to the Gobi grassland, to conduct detonation tests again and again, and found out the implosion law of the atomic bomb.

　　In 1963, Chen Yi asked Wang Ganchang, "When did that thing of yours ring?"

　　Wang Ganchang confidently replied: "In another year."

　　Chen Yi said happily, "Good! With this, my foreign minister’s waist is hard. "

　　At Qian Sanqiang’s suggestion, China has already begun to explore the hydrogen bomb while developing the atomic bomb. After the successful explosion of the atomic bomb, Wang Ganchang, as the vice president in charge of the experiment of the Nuclear Weapons Research Institute, quickly plunged into the hydrogen bomb experiment. At the beginning of 1966, Wang Ganchang, who was nearly 60 years old, worked out a detonation simulation experiment scheme together with the comrades in the experimental department, and solved the key problems in the detonation design technology in repeated "cold experiments".

　　During the development of the hydrogen bomb, China suffered the catastrophe of the Cultural Revolution. Fortunately, under the protection of Zhou Enlai, the cutting-edge science and technology field was relatively calm. But in that special period, Wang Ganchang was still not spared and was criticized. Despite this, he resisted pressure and grievances and always focused on scientific research. After the successful experiment of hydrogen bomb principle, Nie Rongzhen excitedly held Wang Ganchang’s hand, while Wang Ganchang just said meaningfully: "It’s not easy!"

　　In this way, from 1961 to 1978, Wang Ganchang completely disappeared from people’s sight, and when he was closest to the Nobel Prize, he chose to give up.He used the most brilliant 17 years of his life to hide his name and promote a country’s status as a nuclear power.

The picture comes from the Internet.

The fourth season of ＂Extreme Challenge＂ ended successfully, and the four-year ＂classmates＂ are looking forward to a reunion

Man Gang

As Huang Bo lamented, "All the welcomes are grand, and all the parting is unprepared." Amid the reluctance of the "Extreme Troupe" and the audience, last Sunday night, the fourth season of the interactive inspirational experience program vivo "Extreme Challenge" ushered in the closing night. The "Extreme Troupe" passed through the "doors of memory" and helped each other escape from the "time and space tunnel", which hit many viewers in tears.

With the intention of "setting out for a better life", the fourth season of "Extreme Challenge" has created a delicate and profound "blockbuster of the times" through one after another of highly emotional topics. While gaining insight into China’s 40 years of social changes, it has become an experiencer of Chinese stories and a transmitter of the spirit of struggle. The deep exploration of the interaction of stars has also become a major highlight of the fourth season, which has inspired the audience to have a stronger emotional resonance. "Extreme Challenge" has a deep brotherhood for four years, hugging goodbye and looking forward to the reunion. The audience has also sent their blessings, looking forward to the early return of the new season of "Extreme Challenge".

"Extreme Challenge" by Yu Hewei

The "time and space tunnel" of the closing night pierced the heart, and the "extremely challenging group" brotherly love was deeply poked into tears

On the closing night, the program team specially set up a "time and space tunnel" full of beautiful memories from the first season to the fourth season of "Extreme Challenge". During the process of nervous escape, "Extreme Troupe" also had to face successive "Memory Kills" from time to time. The audience couldn’t help but feel distressed: "This wave of challenges is too painful!" But what was more touching was that in the face of the test of survival and the choice of brotherhood, every member of "Extreme Troupe" chose brotherhood without hesitation.

There were many "mechanisms" in the "space-time tunnel", and in the limited escape time, only by opening the "doors of memory" could one continue to move forward. One memory node after another, scene after scene reappeared in the past, stringing together the beautiful memories of the "extremely challenging group" working together from the first season to the fourth season. But the cruel thing is that every time a door is opened, a brother must leave a "key" as the clearance.

In the end, with the help of the brothers, Huang Bo managed to escape from the tunnel, and the memories of the other members would be wiped away and left on the desert island forever. But Huang Bo did not have the slightest joy in challenging the success, "Everyone held on for a while, but they stayed in the tunnel when I came out. The brothers are still on the island, and I really want to stay here, to be with the brothers." At the moment when they were notified that their memories would be cleared, many people couldn’t help but burst into tears. The sad thing was not that they were locked on the island, but that they were reluctant to give up those good memories.

"Times Blockbuster" conveys the spirit of struggle "Extreme Challenge" unlocks the new style of TV variety show

From the first season to the fourth season, the height, width, depth and other dimensions of "Extreme Challenge" have been constantly improving and expanding. In the new season, the program team has the intention of "setting out for a better life", positioning the program as a Chinese story experiencer who has insight into 40 years of social changes, and a carrier of the spirit of struggle, and thus presents a gift to the 40th anniversary of reform and opening up.

It has both feelings and energy, unlocking the new style of TV variety shows. This is also a deep, hot and meaningful innovation exploration made by Chinese TV programs in combination with the background of the times.

The industry has praised that the fourth season of "Extreme Challenge" has been upgraded to a "variety show with great personality". While reflecting social changes, it has turned the spiritual wealth of the 40 years of reform and opening up into a light that reaches people’s hearts, illuminating people’s current lives, and demonstrating the sense of social responsibility and mission that TV media should have. Among them, there is a sense of unity to work together to complete tasks, a fearless spirit in the face of various difficulties, and the courage to strive for a better life. In addition to bringing laughter to the audience, the strong spiritual energy conveyed is even more valuable.

Deeply cultivating the interaction of Xingsu to stimulate strong emotional resonance "Extremely challenging group" looks forward to the reunion and the audience sends blessings together

As a star element interactive inspirational experience program, the fourth season of "Extreme Challenge" further explores the combination of stars and elements. Under the background of insight into 40 years of social changes, through the in-depth real experience of "extremely challenging group" and amateurs, it vividly shows historical nodes and describes the changes of the times. The addition of the new "Extreme Think Tank" really makes amateurs the main body to promote the task process, build story turns, and set the program suspense, which further strengthens the degree of integration of amateurs. A more realistic life scene and a more authentic substitution experience also inspire a stronger emotional resonance among the audience.

The audience expressed their opinions one after another: "In addition to the charming’extremely challenging group ‘, what attracts us to’Extreme Challenge’ is the various down-to-earth star elements in the program, and the theme of each program is closely related to our daily life.

In fact, there are a few moments in a program that can make us unforgettable forever, but this program has never been in vain." The emotional Sun Honglei said a thousand words but didn’t know where to start, and finally turned into a thank you, "Thank you for four years, thank you!" Huang Lei said excitedly: "We have been classmates for four years, looking forward to a better future, just like the beginning of every end." Luo Zhixiang was looking forward to the reunion of the six brothers as soon as possible, and Wang Xun’s eyes were wet: "The four seasons have left too many wonderful memories, and those photos are really treasured in the memory. The six of us will never be scattered." Zhang Yixing also shouted "Extreme Challenge" on the prairie, wishing the brothers "a long-lasting relationship".

"Thank you for every season of’Extreme Challenge ‘, which has brought so much joy and energy to our lives. We will bring your’Extreme Spirit’ to work hard on our own life track and make ourselves better." "Brothers, don’t say goodbye, I believe you will be reunited soon, I believe that the fifth season of’Extreme Challenge ‘will return soon, we are waiting for you!"

The woman was refused a ride in a taxi with her grandmother’s ashes. Driver： It’s too taboo

　　The death of a loved one was undoubtedly a sad thing for the relatives. The pain in his heart had not yet subsided, but at the entrance of the funeral home, he was refused by the taxi driver because he was carrying an urn. I believe that no matter who encounters such a scene, it will be difficult to suppress his anger.

　　On February 22, Miss Zhang and her family in Hangzhou encountered such a scene. The taxi driver first drove them out of the car. After arguing, he simply stopped the car on the side of the road, pulled out the key and left.

　　Passenger:

　　The driver said only the living, not the dead

　　At around 10:30 a.m. on Feb. 22, Ms. Zhang, her parents and aunt drove her grandmother, who was in her 80s, home from the Hangzhou Funeral Home, carrying her ashes. Using Didi’s taxi app, she hailed a taxi with the name "Hangzhou Funeral Home" and the destination was Jinjiang Seafood City.

　　The taxi driver called and said that he was driving a different car today, not the license plate displayed by the software. After a while, the car arrived, and it was a red one. "My mother wrapped the urn in cloth and put it in a travel bag. As soon as the driver saw it, he asked us what it was." Miss Zhang told the truth, and the driver immediately changed his attitude.

　　"Like chasing the god of plague, your attitude is very bad." Miss Zhang said, "Tell us to get off the bus immediately, I won’t take your order, you cancel the order, or call another car, or call a private car, anyway I won’t take it."

　　Miss Zhang asked, "Didn’t you refuse to take the car like this?" The driver said that his car was for business, "and he also said that I would pull the living, but not the dead." This sentence completely angered Miss Zhang’s family, and the two sides quarreled. After a dispute, Miss Zhang said, the driver simply started the car and leaned to the side of the road, unplugged the key and drove away. "He said, you are so powerful, you can drive it back by yourself, and give the car to you."

　　On the service supervision card in the car, the driver’s surname was Zhan. It was still raining lightly at the time, and an angry Miss Zhang called the transportation management’s complaint number and told them that it would take 15 working days to deal with it. She then complained to the mayor of Hangzhou at 12345. Finally, the family took the bus home.

　　The brother in question:

　　Running on the road all day, pulling urns is too taboo

　　Qian Bao reporter also contacted the party, Master Zhan. Master Zhan, a native of Quzhou, has been driving a taxi in Hangzhou for five or six years. The car has only been running for three months and is on the day shift.

　　Mr. Zhan told reporters that he did receive the order at around 10:30 a.m. on Feb. 22. "I saw something in the passenger’s hand and asked what it was. The passenger replied that it was an urn. I felt uncomfortable when I heard it, so I asked them to change the car."

　　Mr. Zhan said he had his own concerns: "We taxi drivers run on the road all day, and we pay attention to safety and prosperous business. There will always be taboos when we encounter this kind of thing. And if other passengers know that my car has pulled the urn, who will ask for my car in the future?"

　　The owner of this car, Master Tian, a native of Henan, has also driven taxis in Hangzhou for more than a decade, but this is the first time he has heard of such a thing.

　　He said that he quite understood Master Zhan. "In my hometown, the private car of the family usually helps to pick up and drop off the urn, so I’m sorry to call the car outside." However, Master Tian also said that communication and attitude are very important. "If Master Zhan could have explained patiently at that time, maybe the passengers would have accepted it."

　　Does my brother think so about this? When the reporter returned from the interview, he asked the driver who was driving by the way. The brother’s surname is Wu, but he doesn’t mind. The key, he said, is his own mentality and concept. "In our service industry, you will encounter all kinds of people and things every day. Correct your mentality and just treat it as a business, but it’s nothing."

　　Operation management:

　　Master Zhan’s behavior counts as refusing to carry and will be punished

　　So, does Master Zhan’s behavior count as rejection?

　　The Hangzhou Municipal Transportation Administration said that refusing to carry passengers is a serious illegal act, but if passengers have any of the following circumstances, taxi drivers can refuse to carry passengers or terminate service:

　　(1) illegally carrying controlled knives, firearms, and other state-regulated devices or flammable, explosive, highly toxic, radioactive, corrosive, and other items that affect public safety;

　　2. Bringing pets and other items that deface the vehicle in violation of regulations;

　　3. Intoxicated or mentally ill people are unaccompanied in a vehicle.

　　4. Require the driver to violate the provisions on taxi management, road traffic management, and public security management.

　　5. Smoking, spitting in the car, defacing the vehicle, or littering with waste.

　　And what Master Zhan encountered is not in the 5 types of situations that can be rejected. At present, the case is being processed. If the investigation is true, it will be dealt with as rejected, with a fine of 300-3000 yuan and 10 points deducted.

　　In addition, Hangzhou Yiyun, the taxi company where Mr. Zhan works, also said that it will deal with the driver’s behavior: deduct 500 yuan in liquidated damages, and suspend business for a day for criticism and education.

　　Funeral home plans to launch "spirit delivery service"

　　The funeral home has considered the fate of Ms. Zhang’s family, but it has not been realized due to limitations in terms of vehicles, personnel, and fees. The staff of the funeral home said that in the second half of this year, the museum plans to launch a "spirit delivery service" to send the ashes of the deceased to the home or cemetery according to the request of the family, which will save a lot of embarrassment and misunderstanding.

Didi has finally made a profit, but why does it continue to spend money on autonomous driving？

Didi is entering a new stage of development of "breaking out of the cocoon and becoming a butterfly".

The latest quarterly earnings report from Didi shows that Didi has achieved its best performance in history. Specifically, while its business and revenue continued to grow and reached a record high, it also ushered in a bright harvest on the financial level: it achieved its first single-quarter profit since delisting from the New York Stock Exchange.

More importantly, Didi’s business structure has also further matured. One of the most typical examples is that Didi’s corporate strategy will further "focus on mobility services", according to Cheng Wei, chairperson and CEO of Didi.

For a travel platform company like Didi, doing something and not doing something is a very challenging business choice. At present, the strategic focus on travel services has pointed to Didi’s "doing something", and Didi’s "doing something" has largely pointed to autonomous driving.

For the current Didi, this is undoubtedly a wise choice.

Towards a rare positive business cycle

From a financial standpoint, Didi is approaching a business cycle based on a mobility service system like never before.

According to Didi’s official financial report for the third quarter of 2023 released on November 13, Didi’s revenue in the third quarter was 51.40 billion yuan, reaching a new historical high and growing by 25% year-on-year.

Among them, the China Mobility business segment achieved revenue of 46.649 billion yuan, an increase of 26.6% year-on-year; the International business segment achieved revenue of 2.034 billion yuan, an increase of 28% year-on-year.

Judging from the order situation, Didi’s order volume in the three quarters continued the growth trend of the previous two quarters as a whole, and the total order volume of the core platform reached 3.579 billion orders, an increase of 34% year-on-year. Among them, the total order volume of China’s travel business was 2.878 billion orders, an increase of 32% year-on-year; the total order volume of international business was 701 million orders, an increase of 43% year-on-year. In this way, the average daily order volume of China’s travel in the third quarter reached 31.30 million orders, breaking through the historical peak of a single quarter.

For this order volume performance, Didi said that around the summer, concerts and other popular travel scenarios, Didi continued to up the ante refined operation in the third quarter, issuing multiple taxi benefits to users, and further driving travel demand growth. In the third quarter, the total transaction volume (GTV) of Didi’s core platform was 91.50 billion yuan, an increase of 37% year-on-year. Among them, the total transaction volume of China’s travel was 72.50 billion yuan, an increase of 33% year-on-year; the total transaction volume of international business was 19 billion yuan, an increase of 52% year-on-year.

Of course, in order to promote the expansion of the overall revenue plate, Didi’s revenue costs are also expanding.

According to the financial report data, Didi’s cost in the third quarter of 2023 was 43.40 billion yuan, accounting for 84.4% of revenue; the cost in the same period of the previous year was 33.70 billion yuan, accounting for 81.9% of revenue. In this regard, Didi explained in the financial report that the increase in revenue costs as a percentage of revenue was mainly due to the increase in costs related to China’s online car-hailing business.

But the good thing is that Didi has made efforts to improve operational efficiency.

Specifically, Didi’s sales and marketing expenses in Q3 2023 were 2.80 billion yuan, accounting for 5.4% of revenue, and 6.1% in the same period last year. At the same time, Didi’s management fee in the third quarter of 2023 was 2.20 billion yuan, and the same period last year was 2.30 billion yuan. The management fee rate decreased from 5.5% in the same period last year to 4.2%.

It can be seen that when the proportion of sales and marketing expenses and management fees is decreasing, it can be seen that Didi’s operational efficiency is indeed improving.

Let’s take a look at the profitability again.

Didi’s adjusted EBITA loss in the third quarter was 315 million yuan, compared with 308 million yuan in the same period last year.

Among them, Didi’s adjusted EBITA from China’s travel business in Q3 2023 was 1.47 billion yuan, down 26.1% from 1.988 billion yuan in the same period last year; Didi’s adjusted EBITA from international business travel in Q3 2023 was – 795 million yuan, down 9.2% from the same period last year – 876 million yuan. Adjusted EBITA loss for other business segments was 990 million yuan, down 30.3% year-on-year.

It is worth mentioning that Didi’s ROI recorded in Q3 2023 was 1.10 billion yuan, and the ROI in the same period of the previous year was 200 million yuan. Didi’s ROI in 2022 is mainly related to the fair value gain of the company’s investment in Grab, while Didi’s ROI in 2023 is mainly related to the unrealized gain arising from the spin-off of its subsidiary engaged in autonomous trucking.

From the final results, according to GAAP standards, Didi’s net profit in the third quarter was 376 million yuan, compared with a net loss of 1.764 billion yuan in the same period last year.

In addition, as of September 30, 2023, Didi’s cash and cash equivalents, restricted funds and wealth management investment balances were 54.60 billion yuan, an increase from 48.80 billion yuan as of December 31, 2022. At the same time, Didi disclosed that it will carry out a repurchase plan of no more than 1 billion US dollars in the next 24 months.

Overall, on the basis of the expansion of the overall revenue plate, Didi has continuously improved operational efficiency, reduced the scope of loss-making business, and achieved overall profitability under GAAP standards through investment and other means. Under the new business rhythm, Didi has shown a positive trend as a whole.

From the perspective of its overall development process, this time, Didi has achieved its best performance in history since its inception.

The smart choice for Didi’s strategy: Focus

Didi’s financial performance in the third quarter of this year has actually been fully and accurately explained in the evaluation of Cheng Wei, chairperson and CEO of Didi Chuxing.

Cheng Wei said that thanks to the continuous recovery of domestic travel demand, Didi’s various businesses continued to grow steadily in the third quarter. Objectively speaking, the reason why Didi Chuxing was able to achieve more than 25% revenue and order growth is indeed closely related to the rapid growth of travel demand after the end of the epidemic. This factor can be regarded as a favorable external condition for Didi’s development.

However, from the perspective of Didi itself, Cheng Wei’s next sentence revealed the secret of Didi’s ability to grasp the growth of technology, that is, "the company’s strategy further focuses on mobility services". If the core keyword is extracted, it is "focus on mobility services".

Indeed, focusing has become the choice that Didi Chuxing, a travel service platform company rooted in China, has made in the past few years.

A very typical example is that as early as 2020 and the first half of 2021, Didi was also frantically involved in the battle of community group buying and sank the sand, but in the following year or two, Didi actively or passively gave up this business sector. Now, it has completely withdrawn from this muddy water.

Even just from the third quarter of this year, Didi has carried out its strategy through a number of actions in "focusing on mobility services".

Among them, the one that has attracted the most attention from the outside world is undoubtedly the transfer of the smart electric vehicle project to Xiaopeng in August this year.

More specifically, at the end of August this year, Didi Chuxing announced a strategic cooperation with XPeng Motors to sell its previous electric vehicle project-related assets and R & D capabilities to XPeng Motors, which itself owns shares in XPeng Motors. In addition, the two sides also cooperate on automobile operation, brand marketing, financial insurance services, charging facilities, international markets, etc.

For Didi, the cooperation with Xiaopeng is undoubtedly wise. After all, the smart electric vehicle project is a very expensive asset-heavy business. For an Internet company like Didi, the qualification itself is a big issue, not to mention the huge capital and business risks involved.

In essence, the smart electric vehicle business is indeed not what Didi is good at. It is related to Chuanqiang, but it does not belong to the category of "service" at all, so it is essentially different from "travel service". Therefore, Didi chose to cooperate with XPeng Motors to sell the business and obtain shares in XPeng Motors, essentially returning to the asset-light model that it is familiar with and good at.

So the abandonment of the smart electric vehicle project reflects Didi’s "focus" on Chuxing services, which is indeed very sensible.

In addition to its partnership with XPeng Motors, Didi Chuxing’s focus on "mobility services" was also reflected in another partnership announced in the third quarter.

On September 6, Didi’s Didi Car Rental and Heyi Car Rental jointly announced that they have reached a cooperation, and will jointly explore various fields such as vehicle rental, network services, marketing promotion, and new business scenarios to jointly provide users with more value-added and convenient travel services.

In fact, the cooperation between Didi Car Rental and Ehi Car Rental is the first time that Didi Car Rental is directly connected to the domestic head self-operated car rental brand. Users open the Didi Chuxing App and click "Ehi Special Offer" from the "Didi Car Rental" model list page to quickly filter. You can rent vehicles from Ehi 11,000 multiple direct outlets across the country. In this cooperation, the two sides also plan to try new usage scenarios and usage models in the car rental business, and jointly explore new space in the car rental market. For example, more attempts and explorations are made in scenarios such as commuter car rental and instant cross-city car rental to further enhance the user experience.

Obviously, the cooperation with Ehi Car Rental is another important layout for Didi to continuously expand its services around the travel scene and meet the diverse travel needs of users. It should be noted that the attributes of this cooperation itself are still asset-light, and the business itself is completely under the category of "travel services".

Of course, in addition to the above two collaborations, Didi Chuxing’s focus on travel services is also reflected in its many daily operation dynamics in the third quarter, including the launch of "barrier-free travel services for the blind" nationwide, the participation of "Didi public welfare rescue team" in disaster relief work, the upgrading of student rights and interests, the establishment of a freight driver ecological service committee in the freight business, and the launch of 1 billion subsidies during the double holiday.

These are all manifestations of Didi’s "focus on mobility services".

It is worth mentioning that it is precisely because of Didi’s continued layout in the travel service that in September this year, Didi Chuxing also successfully ranked 14th in the "2023 China Top 100 Service Private Enterprises" list released by the All-China Federation of Industry and Commerce, which is undoubtedly a great affirmation of Didi as a travel service enterprise.

Autonomous driving, supporting an imaginative space

There is no doubt that the core corporate strategy of "focusing on mobility services" has strongly supported Didi’s "present" in business and financial aspects; at the same time, as an Internet technology company, Didi also needs to build a "future" with broad imagination for the market and investors.

It is clear that this "future" of Didi is built on autonomous driving.

In fact, if we look at the timeline of setting up a team in 2016, Didi’s autonomous driving business is actually the business that Didi has the longest and most committed in many businesses, and it is also the business that best reflects Didi’s technological attributes as a travel service company.

At present, Didi is also making multi-line deployments in the field of autonomous driving.

One of the most obvious and important lines is undoubtedly the cooperation with GAC Aian for the layout of L4-level driverless taxis.

In fact, as early as May 2021, Didi’s autonomous driving company announced a strategic cooperation with GAC Aian, the purpose of which is a driverless new energy model that can be put into large-scale application. But this cooperation was stranded for a time, and it was not substantially advanced until May 2023. Didi Autonomous Driving Company and GAC Aian New Energy Vehicle joint stock company jointly released the driverless new energy production vehicle project "AIDI plan" and announced that they will establish a joint venture company.

According to the AIDI plan, Didi Autonomous Driving and GAC AEAN will establish a joint venture. The first mass-produced model will be based on GAC AEAN AEP3.0 pure electric platform, Xingling electronic and electrical architecture and multi-fusion perception autonomous driving mass-production technology, equipped with Didi Autonomous Driving L4 urban generalization engine and autonomous driving technology solutions for travel services, to create driverless new energy vehicles. Not only that, the production car will be connected to Didi’s shared travel network in 2025.

In October this year, GAC Capital, a wholly-owned subsidiary of GAC Group, and Guangzhou Development Zone Investment Group announced the establishment of a special project fund jointly funded by the same proportion, investing no more than 149 million US dollars in Didi Autonomous Driving; through this investment, Didi Autonomous Driving will continue to increase investment in technology research and development, accelerate the promotion of product application and open cooperation in the industrial chain.

Therefore, it is obvious that on the road to promoting L4 driverless taxis, Didi’s autonomous driving has been firmly tied to the deep-pocketed GAC Group, relying on Didi’s leading strength in autonomous driving technology and scene data systems.

In addition to Robotaxi, another business breakthrough point for Didi’s autonomous driving is the mass production of new energy heavy trucks at the L4 level.

In fact, at the Guangzhou Auto Show held not long ago, Didi Autonomous Driving showed a front-loading L4 new energy heavy truck. It was jointly launched by Carl Power, an incubator of Didi Autonomous Driving, and Shaanxi Automobile. It is equipped with the hybrid intelligent formation system developed by Carl Power. From a business perspective, it is a hybrid unmanned solution that can empower logistics and transportation scenarios through intelligent driving.

At present, Karl Power has carried out normal testing and operation in North China and Northwest China, providing intelligent transportation in complex scenarios such as short, medium and long-distance, and transporting over 2.50 million tons of bulk goods every year.

It can be said that through the layout of L4-level front-loading mass-produced new energy heavy trucks, Didi’s autonomous driving tentacles have also penetrated into the field of smart logistics from the perspective of human travel needs.

Of course, in addition to cooperation with car companies, Didi is also deploying some core components and technologies in autonomous driving. For example, the three-domain integrated computing platform "ORCA Orca" developed by Didi Autonomous Driving, and the lidar "North BETA" jointly developed by Didi and Beixing, etc. These businesses are essentially intelligent layouts carried out by Didi to achieve L4-level autonomous driving.

From the bottom, Didi’s layout in the field of autonomous driving is still a light asset logic that relies on partners, empowers partners, and connects partners. This is indeed more conducive to Didi from the perspective of Internet platform enterprises to play its own intelligent and shared value without having to bear huge financial exposure.

Of course, overall, Didi’s layout in the field of autonomous driving is still in the investment stage, and to see its actual value in terms of business returns, it may have to wait until 2025 at the earliest.

As a mature enterprise, Didi

In China’s Internet platform enterprises, Didi has always been a special presence.

For example, it was born in the wave of China’s mobile Internet development, and it naturally has its own technological attributes; it has grown up with the continuous feeding and support of multiple capitals, which makes it more necessary to consider the balance between short-term returns and long-term investment at the financial level; but at the same time, the travel track it is in is a highly regulated industry, and safety must be the first red line… This itself is "walking a tightrope of balance".

Such enterprise attributes are destined to make Didi’s development difficult, making it appear to be stumbling.

But now, after a series of setbacks and adjustments, Didi has found its place in the ever-changing industry landscape, focusing on the strategic foundation of "mobility services", and has also found its own development rhythm, taking autonomous driving as the core competitiveness for the future.

Do something, do something. In other words, Didi has finally learned the correct posture of "balancing the tightrope".

Such a Didi, although it is no longer the Didi that seeks crazy expansion and constantly seeks various possibilities, is a more pragmatic, more mature, more stable and more responsible platform enterprise. More importantly, on the track of autonomous driving, it continues to run and intends to build a long-term enough future with a smarter attitude.
