Bo Huang: How did the legend of the film-winning emperor who walked out of Qingdao’s alleys make him what he is today?

Today, there are many shining stars in the entertainment circle in China. With his unique life experience and outstanding talent, Bo Huang wrote a legendary story from ordinary to great. His name has become synonymous with persistence and dreams. Bo Huang, a person who interprets the word "grassroots" incisively and vividly, how does he move from Qingdao alley to the glory of the film emperor?

Early experience: indomitable spirit of struggle

Bo Huang was born in Qingdao in 1974. Since childhood, he has shown a strong interest in art. Different from his peers in other entertainment circles, Bo Huang came from an ordinary family. There was no special glory in his adolescence, but an ordinary and unknown singing career with his family. During that time, he often told his dreams in bars and nightclubs by singing and worked to earn tuition and living expenses.

In the streets and lanes of Qingdao, the audience heard his singing, but no one knew about the young man’s future achievements. Bo Huang said: "I like the stage because it provides a platform to express myself." During these performances, he gradually honed his singing and performance skills and accumulated valuable stage experience.

Career Transformation: The Challenge from Singer to Actor

At the beginning of the 21st century, Bo Huang is facing a turning point in his life. He decided to transform from a resident singer across the border and seek a broader development space. In 2006, Bo Huang entered the audience’s field of vision as a simple and witty character in the movie Crazy Stone. This role, like the igniter of his life, made him unexpectedly famous and paved the way for more film and television works.

This film is not only a box office carnival, but also allows Bo Huang to accumulate a lot of audience base. With the release of a series of successful works, including "Flowers in the Heart", "No Man’s Land" and "Journey to the West", Bo Huang gradually established his own performing position and became a first-line actor in China films. But along the way, he has also experienced numerous challenges and setbacks. In some plays, his voice of being questioned is endless, but he always takes every criticism as an opportunity to hone himself.

Widely recognized: the elegant demeanor and achievements of the film emperor

Bo Huang’s artistic career has come to a climax with the passage of time. In many important film festivals, he won many awards, including Hundred Flowers Award, Huabiao Award, Golden Horse Award and so on. In 2018, he won the Best Actor in Golden Rooster and Hundred Flowers Film Festival, which fully demonstrated his extraordinary strength in performing arts. Bo Huang proved with strength that grassroots origin can also fly to the starry sky of dreams.

On several podium, his humble and sincere speech is always impressive. "Being able to stand here and accept the honor is the result of all my efforts. Thank you for supporting me all the way. " His humility and kindness won him a good reputation in the public mind, which also aroused the resonance of many young people’s dreams.

Personal life: family-oriented warmth

Although Bo Huang was at the height of his acting career, he never forgot the importance of his family. His wife and children have always been his staunchest supporters. No matter how busy he is at work, Bo Huang always finds time to spend with his family and enjoy rare family time. He believes that family is the source and motivation of his success, and this warmth keeps him awake in the flashy entertainment circle.

"I hope my children can pursue their dreams, not feel pressured by my success." Bo Huang once said. This attitude made him show a father image with both pursuit and responsibility in public.

Giving back to the society: a firm step in public welfare undertakings

In addition to his achievements in performing arts, Bo Huang also actively participated in social welfare. He has participated in many charitable projects to help children in poor areas. He believes that giving back to the society in his own way is the best interpretation of his achievements. Bo Huang revealed that he hoped to attract more people to pay attention to social issues through his influence.

At a charity event, Bo Huang said with emotion: "We all have the ability to change something, as long as we are willing to pay." This positive attitude has made him an idol in the eyes of the public, not only in the performing arts, but also in the responsibility of human nature to society.

External evaluation: the clean flow of entertainment circle

Today, Bo Huang has become a legend in the entertainment circle, sought after by numerous media and loved by the public. He is known as "the most grounded film emperor", and he has won wide respect including his peers with his own strength and character. Whether it is the role in front of the screen or him in life, it is always impressive.

In the eyes of many people, Bo Huang’s success is not accidental, but the accumulation of unremitting efforts over the years. He used practical actions to show what real dreams and achievements are, and his story also inspired countless dream-seekers.

Summary: Truth and Enlightenment

Bo Huang’s legendary experience tells us that grassroots is not an obstacle to success, but the starting point of life. Only with dreams and unremitting efforts can we create a bright life. In this fast-paced world, Bo Huang’s persistence and self-confidence are the best inspiration.

In the future, Bo Huang will continue to explore on the road of performing arts, repay the audience with richer angles and works, and continue his legendary story. At any time, Bo Huang is using his every step to interpret his beliefs and pursuits. Let’s look forward to his wonderful performance on the future stage!

Air suspension+electromagnetic shock absorber! Analysis of Tengshi N7 Chassis

  [Interpretation of car home’s Fresh Technology] (|) The order has been broken by 20,000, and from the feedback of the previous test drive video, netizens are most interested in the cloud technology carried on the chassis of this car. As it happens, I visited BYD’s manufacturing base in Jinan some time ago. This base is one of BYD’s latest bases, which mainly undertakes the production and manufacturing of dolphins and Tengshi N7, and the engineers responsible for Tengshi N7 chassis and BYD Yunqi also work here. This article will talk to you in depth about my feelings about this chassis and its technical characteristics.

Home of the car

The type of cloud chariot

  First of all, we need to know the general distribution of cloud technology. For a better understanding, we can compare it to four students at different stages.

Home of the car

  Yunqi -C (primary school students), Yunqi -A (junior high school students), Yunqi -P (senior high school students) and Yunqi -X (college students). As you can see, this set of technical logic is from the lowest C to the highest X. Among them, under the same big technical framework, it may be further subdivided, and they will have subtle differences in their capabilities.

● Is Yunxiao an active suspension?

    Some time ago, many netizens in the forum debated whether the ideal air suspension was an air suspension, and later it was extended to the cloud of Tengshi N7. Regarding the ideal air suspension, our previous video has been deeply interpreted, so you can review it. (Interpretation of Ideal Magic Carpet Suspension)

Home of the car

    For Yunqi, the current situation is as follows: Yunqi -C (primary school students), Yunqi -A (junior high school students), Yunqi -P (senior high school students) and Yunqi -X (college students) are all basic or standard versions, among which Yunqi

Home of the car

  Let’s talk a little more here. Tengshi’s engineer said: The sold models with electromagnetic suspension, such as Tengshi D9, can be upgraded to a cloud in the future through OTA. At the same time, through the decentralization of the algorithm, road information can be collected by the camera, road characteristics can be identified in advance, and the damping of the shock absorber can be adjusted to realize the function of active suspension.

● Return to theme: Tengshi N7 suspension analysis and Yunnian -A composition.

  OK, through the above explanation, I believe everyone has a general understanding of Yunqi. Let’s take a detailed look at the chassis of Tengshi N7 and share the specific riding experience of Yunqi-A.

  The central controller is placed in the middle of the car body, just like the brain, which obtains the sensor information first, and then gives the information to the air spring and shock absorber to adjust the height and damping.

Home of the car

  At this stage, the cloud chariot -A system of Tengshi N7 is still a semi-active suspension, strictly speaking. Why? Let’s take a look at its working process:

Home of the car

  Readers, have you noticed that all the sensor information is passively obtained after driving? Even if the central control unit can output the adjustment strategy very quickly, it is still passive. Therefore, at this time, Yunqi -A is still considered as a semi-active suspension.

Home of the car

  However, BYD will certainly not stop there, and "cloud preview" has appeared. Cloud preview is not exclusive to A, it belongs to all four suspension technologies mentioned above, and we can understand it as the PRO version of each suspension version (let’s call it PRO version for the time being), which is mainly viewed in combination with the vehicle model. For example, the version of Tengshi N7 with laser radar can upgrade the cloud preview. Its function is to identify the road characteristics in advance. It will scan the road information through the camera module and the laser radar, calculate the drop of 5-150m, and adjust the suspension in linkage.

  At present, Tengshi N7 has not been upgraded to this function, but in the communication, engineers also revealed that they will release this PRO version of Yunbi -A when Tengshi N7 Intelligent Driving Edition is launched, so we have reason to believe that this active suspension will also be linked with intelligent driving, such as high-speed NOA, which can predict the curvature of the front curve in advance through navigation to adjust the suspension hardness.

● Overdeceleration brings surprises, and the low-frequency resonance needs to be improved.

  Then, let’s talk about the actual feeling of Yunqi -A Standard Edition in the test scenario.

More exciting videos are all on the car home video platform.

  Of course, there are advantages and disadvantages. I think it is mainly reflected in the following aspects.

  First of all, the sports mode is not enough. When entering the sports mode, the air suspension of the vehicle is not linked, but the damping of the shock absorber is increased.

  The second is that when passing through the washboard road, the back row occasionally resonates, and sitting in the back row will make you feel uncomfortable.

Write at the end:

  The above is all my experience and content sharing of Yunqi -A this time. Let’s make a simple review and summary. N7′ s Cloud Web -A has a set of self-developed complete system architecture: it is composed of Cloud Web perception architecture, central processing unit, intelligent control technology and key components, and builds a complete architecture of perception, decision-making and execution. Among them, the central processing unit is the "central nerve" of Yunnian -A system, which can retrieve the signal data of all the sensing layers of the vehicle, actively perform high-speed calculation on the body posture and wheel load through the self-developed algorithm, and output the control strategy in real time.

  Secondly, the function of Cloud -A of N7 does not include preview function when there is no optional high-level intelligent driving exclusive package, but it does not affect the realization and experience of the above functions such as height adjustment and damping adjustment of Cloud-A..
  Third, Tengshi’s engineer said that the model I experienced this time is still a trial installation, so the second deficiency mentioned above will be improved. As for the first sport mode, they are already developing and updating, and will make comfort mode and sport mode more differentiated in the future. At the same time, they will also listen to the suggestions of car owners, and finally improve the quality of suspension and chassis through OTA. Let’s look forward to the future Tengshi N7!

Cadillac’s new SUV will be launched on November 25th. It is estimated that it will start at 240,000.

  According to the plan, Cadillac will launch an entry-level luxury SUV with the internal code name "E2QL". Judging from the EIA information, it is expected to be positioned as a compact coupe SUV. Not long ago, the patent drawing of Cadillac GT4 with cross-border modeling was exposed. The characteristics of this car are basically consistent with E2QL, and it should be the same model. The online auto market learned that Cadillac E2QL will make its debut on November 25th.

  E2QL and Buick Angkor S are both built on the existing E2 platform, with overall dimensions between Cadillac XT4 and Angkor S, providing 1.5T and 2.0T power, and will compete with Audi Q3 coupe, Mercedes-Benz GLA and BMW X2 in the future. Considering the positioning of E2QL is lower than XT4, and referring to the price difference between SUV models and competing products, it is estimated that the starting price of new cars may be around 240,000 yuan.

  Cadillac GT4 adopts the latest family design, and the interior is expected to be equipped with a 34-inch central control screen of Cadillac’s new generation entertainment system, which is expected to use the same screen as Cadillac LYRIQ(33-inch). The new roof version is expected to provide electric 8-way adjustment of the main and co-pilot seats, 4-way lumbar support and heating and ventilation functions.

  Cadillac E2QL is equipped with GM’s latest 1.5T and 2.0T engines. The 1.5T engine is the same as Buick Weilang Pro, and the 2.0T engine has the same 48V light mixing system as Angkewei S, and the transmission system is matched with 9AT gearbox. The new car 1.5T is a front-wheel drive model, and 2.0T is a four-wheel drive model. The acceleration of 100 kilometers is 8.9 seconds and 8.2 seconds respectively.

BYD has lived up to its expectations this time, and the interior has been upgraded.

Space is precious, quality and price are higher. Nowadays, the first thing for consumers to buy a car is to see whether this car is rich in configuration, and it is no exception to nature. So whether this car is a mule or a horse, let’s take a look at its actual performance.

First of all, from the appearance, the front of Qin New Energy looks very capable, with a multi-spoke air intake grille, which looks sporty. Coupled with the atmospheric headlights, the exquisiteness of the whole vehicle has been greatly improved. The car is equipped with LED daytime running lights, automatic opening and closing, delayed closing and so on. Coming to the side of the car body, the car body size is 4675MM*1770MM*1500MM, and the car body looks very elegant with large-sized thick-walled tires, which is eye-catching. Looking back, the rear of the car looks very atmospheric, and the taillights give people a very calm feeling, and the sense of neatness is vivid.

When I got into the car, Qin New Energy’s interior looks more individual and makes people feel very cold. The steering wheel of the car is very in line with the interior style, made of plastic and full of design. Let’s take a look at the central control. The design of the center console is reasonable, which makes the interior style impressive and looks deep. Finally, let’s look at the dashboard and seats. The car is equipped with a simple dashboard, and the information is easy to read and clear. The car adopts imitation leather seats, and the seat wrapping is in place, and the overall comfort and wrapping are not bad.

Qin new energy matched gearbox, 100KW, 180N.m, with good power performance.

The car is equipped with traction control (ASR/TCS, etc.), Bluetooth /WIFI connection, cruise control, intelligent key, sun visor mirror and other configurations, which fully ensures the convenience and comfort of the car experience.

The Qin New Energy introduced today is not only eye-catching in space, but also the configuration has reached the mainstream level, and there is nothing to be picky about driving experience and space experience. If you have plans to buy a car now, then today’s car is worth learning about.

Bao Beier starred in "Big Red Packet", leading the New Year’s Eve file exposure word-of-mouth special.


1905 movie network news Directed by, starring, starring,,,, and so on, the first comedy film of the opening year topped the single-day box office champion for four consecutive days, winning nearly 60.52 million yuan in box office, and the word-of-mouth burst to lead the new film in the same period. The film not only has a hilarious plot of high-energy reversal, but also has a realistic observation that directly hits people’s hearts.

The film released a word-of-mouth special on January 26th, which truly recorded the hilarious comments in the cinema. The audience enthusiastically praised: "This is the movie I have seen laughing the most in the cinema!" "Laughing crazy!" Some people even said that they were stabbed with a red envelope, and they also wanted to "rent a Clara to go home for the New Year" and take back the money sent out in these years.

 

Top box office champion for 4 consecutive days, and the audience was crazy with laughter.

 

After the film "Big Red Packet" was released, it broke through the tight encirclement and successfully topped the single-day box office champion for four consecutive days. Up to now, the cumulative box office has reached 60.52 million, and the word-of-mouth box office has led the new film in the same period. Many fans have become "tap water" fans, taking the initiative to release Amway’s hilarious comedy on the eve of the Spring Festival.

The film released a word-of-mouth special to record the real feelings of the amateur audience. The film was full of laughter for 2 hours. In the interview after the movie, several young people were still immersed in the joyful mood from ear to ear, and they all praised: "This is the movie that I have seen with the most laughter in the cinema!" "Special decompression!" "Unique comedy, very suitable for Chinese New Year!"

 

It’s not hard to find that the movie really touched ordinary fans by browsing the comments on social networks. During the interview, the audience counted the most hilarious scenes: "As long as Liu Haizhu (Xu Juncong) comes out, it will be so funny." "The blind couple in Wang Xiaoli is so funny." "There is no red envelope in the office. Zhang Yiming took out a box of red envelopes and laughed!" The film critic Da V issued a strong message: "At the moment when the epidemic is shrouded," The Big Red Packet "is worth going to the cinema. Maybe a stalk in the film will make you show a long-lost smile. For this reason, this ticket is worth it!"

 

"Special Laughing Day Group" takes you to celebrate the New Year in advance, and the pain of red envelopes pokes the pain points of China people.

 

The reason why the film "Big Red Packet" can win people’s favor is first attributed to the luxury comedian lineup that can be called the Spring Festival Evening of the film. Bao Beier, Zhang Yiming, Jia Bing, Xu Juncong, and Wang Xiaoli’s "Special Laughing Day Group" appeared in unison, which can be called a combination of national faces in the Spring Festival. In addition, the film also depicts the realistic issues full of fireworks, and writes the pain of red envelopes into the story that everyone in China has a deep understanding of, which can make you and I feel the same way and lead to many discussions. Entertainment critic V Beijing Eight Bitches praised: "The appearance of comedy implies a discussion of customs and human nature. Regarding the social reality that the custom of red envelopes shines into, each of us will be disgusted, but the film uses a clever setting, one ring at a time, and always puts the audience in the plot. "

 

Undoubtedly, the arrival of "The Big Red Packet" catered to the audience’s desire for the New Year comedy, which undoubtedly became a shot in the arm for the film market in January. In the special edition, the audience expressed that they had been poked at the pain point, and they understood that Chen Zhong (Bao Beier) could not bear the pain of human feelings, and they also wanted to find a reason to recover the money. "I want to give my pet a birthday (to get back the money)." "If you are not married at the age of 30, you will have a 30-year-old birthday." Some viewers laughed and said that the Spring Festival is approaching, so we should quickly rent an object to go back to our home to hasten marriage. "We must rent a civil servant" and "we must find it according to Clara’s standards".


ARCFOX polar fox finally compromised, polar fox alpha t purchase manual

The richness of the configuration is closely linked to the cost performance of a car, and many people have mentioned it. Next, let’s see if its highlights can attract you with Xiaobian.

First of all, from the appearance, the head style of the extreme fox Alpha T looks very angular and very recognizable. At the same time, the headlight presents a full design style with high recognition. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light, delayed closing and so on. Come to the side of the car, the car body size is 4788MM*1940MM*1683MM, the car uses simple lines, the side looks very avant-garde, with large-size thick-walled tires, giving people a very sporty feeling. Looking back, the overall shape of the rear of the car echoes the front of the car, and the taillights are more elegant and comfortable.

Sitting in the car, the interior adopts a stable design and is rich in functions. The car’s steering wheel is eye-catching, equipped with electric up and down+front and rear adjustment, steering wheel memory, steering wheel heating and other functions, and the visual effect is good. Let’s take a look at the central control. The car is equipped with a unique touch-sensitive LCD central control screen, which makes the interior style impressive and gives people a sense of spirit. Let Xiaobian introduce the dashboard and seats. The car is equipped with a simple and fashionable dashboard, which looks very unique. The car adopts imitation leather seats, which are spacious and thick, with exquisite materials and comfortable ride.

The polar fox Alpha T is 320KW, the total torque is 720N.m, and the maximum speed is 180 km/h..

The car is equipped with car networking, driving mode selection, remote control key, Bluetooth key, rear wiper, interior atmosphere light and other configurations, and the configuration performance is relatively good, which improves the convenience of drivers to some extent.

After reading this car, I believe you have a general understanding. Such a car with the right price can meet the daily practical needs, and it doesn’t take much thought to maintain it at ordinary times, and the price is good.

AITO asks for another subversive question. M9 is the first choice for cost performance.

The progress of industry has actually made the current cars have more reliable quality, and people often pay more attention to the value of vehicles. In the competition with the same class models, it is worth mentioning in terms of space performance. Let’s get to know each other.

Let’s take a look at the appearance of the M9. The front of the M9 is very spirited and sporty. Combined with the headlights, the design is more fashionable and generous. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light, automatic steering, delayed closing and so on. Coming to the side of the car, the body size of the car is 5230MM*1999MM*1800MM. The car adopts fashionable and generous lines, and the side gives a very deep feeling. With large-sized thick-walled tires, the shape is eye-catching. In terms of the rear end, the rear end and the front end echo each other from a distance, the taillight style is relatively young and fashionable, and the overall shape is still very attractive.

Arriving in the car, the interior of the M9 in Wenjie presents a comfortable design style and is full of fighting atmosphere. The steering wheel of the car is very simple in shape and made of leather, which looks a little more streamlined. From the central control point of view, the design of the center console is reasonable, which makes the interior style impressive and has a certain sense of science and technology. Finally, let’s look at the dashboard and seats. The car is equipped with a simple dashboard and looks more dynamic and lively. The car uses leather seats, equipped with auxiliary seat with memory electric adjustment, seat with memory electric adjustment, seat proportion down and other functions, and the overall comfort and wrapping are not bad.

The M9 matching gearbox is 390KW and 673N.m, with good power performance.

The space performance of the M9 trunk is not bad. After putting down the rear seats, it can further expand the space, and its carrying capacity is great enough to meet daily household needs. At the same time, the car is equipped with fatigue warning, anti-lock braking (ABS), LED daytime running lights, brake assist (EBA/BAS, etc.), brake force distribution (EBD) main driver airbag, co-pilot airbag, side airbag curtain, front airbag and rear airbag.

After reading the above description, Xiaobian will make a summary. This class of cars can often give consideration to both cost performance and practicality, and is often considered by most consumers as the first choice when buying a car.

Paper 6: video composer: comprehensive video synthesis with motion controllability

Authors: Xiang Wang et al

Paper link: https://arxiv.org/abs/2306.02018

Abstract: In the field of AI painting, Composer proposed by Ali and ControlNet proposed by Stanford led the theoretical development of controllable image generation. However, the exploration of controllable video generation in the industry is still in a relatively blank state. Compared with image generation, controllable video is more complicated, because besides the spatial controllability of video content, it also needs to meet the controllability of time dimension. Based on this, the research teams of Alibaba and Ant Group took the lead in making an attempt and put forward VideoComposer, which realizes the controllability of video in both time and space through combined generation paradigm.

In this study, the performance of VideoComposer is directly tested on nine different classic tasks, and satisfactory results are obtained, which proves the universality of VideoComposer.

Recommendation: Video generation with controllable time and space has come into reality, and the new work VideoComposer of Ali’s big model is on fire.

Paper 7: simple and controllable music generation

Authors: Jade Copet et al.

Paper link: https://arxiv.org/pdf/2306.05284.pdf

Abstract: At the beginning of the year, Google launched MusicLM, a big model of music generation, and the effect was very good. Some people say that this is more important than the ChatGPT of the fire, which almost solves the problem of music generation. Recently, Meta also launched its own text music generation model, MusicGen, which is free for non-commercial use.

Enter the first two sentences in the lyrics of Jay Chou’s "Qi Li Xiang" as follows: "The sparrow outside the window talks on the telephone pole, and you say this sentence is very summer-like" (in Chinese).

Recommendation: Meta open source text generates a big music model, and we tried it with the lyrics of Qilixiang.

I won’t die until I see my own engine.

  Never give up ambition


  Yang Zibin became a designer by diligent self-study as a workshop worker, so he was highly appreciated by Wu, and they also established a profound friendship. With the deepening of understanding, Yang Zibin admired Wu Daguan more and more. "Wu Lao only focused on one thing in his life, that is, designing and developing aero engines." Yang Zibin praised. Although, this way he walked twists and turns and how difficult-


  After graduating from the Aviation Department of Southwest Associated University in 1942, Wu Daguan got a job in Guizhou Dading Engine Factory opened by the Kuomintang, and was sent to the United States to study for three years. When he returned to China with great ambition to realize his dream of "saving the country by aviation", he hated the corruption and incompetence of the Kuomintang, and he resolutely chose to leave.


  The Communist Party of China (CPC), a young man who is interested in serving the motherland and an advanced political party representing the people, fell in love at first sight in Peiping before liberation in 1949. The latter ignited the hope in the former’s heart, and the former devoted himself to it.


  After the founding of New China, Wu Daguan organized and prepared the Aviation Industry Bureau as the director of the second production department. In 1956, he applied to be transferred from an institution to Shenyang Liming Aero-Engine Factory (hereinafter referred to as Liming Factory) and led the establishment of the first aero-engine design office in New China. In June 1958, the first jet trainer engine in China-Eruption 1A was successfully developed.


  At that time, China was poor, and everything needed to be done, so it was difficult to develop aero-engines. Wu Daguan led the scientific and technical personnel to cut through the thorns. At that time, the employees of Liming Factory often saw such a scene: Wu and his comrades were sitting on the grass and discussing issues enthusiastically. In August, 1961, the Engine Design Institute of Aviation Research Institute was established, with Wu Daguan as the deputy director, and the first engine test base in China’s aviation history was established …


  Wu Daguan said: "I will die unsatisfied if I can’t see the engine developed by our country." However, in the process of exploration and progress, he met unexpectedly during the ten-year Cultural Revolution. He was put in a bullpen, lost his freedom, and became blind in his left eye because of delayed treatment.


  However, Wu Daguan always believed: "The Cultural Revolution does not represent the party, and the line of the party’s’ science and technology power’ will not change." He sealed foreign technical magazines in red and kept on studying.


  At the end of 1977, shortly after the end of the Cultural Revolution, Wu Daguan was transferred to the position of deputy director of Xihang Airlines. "At the age of 62, he will be used at the age of 26." He led the scientific and technical personnel to master the advanced Spey engine technology in the world at that time and successfully developed the imitation. China’s aero-engine industry was about to turn a new page, but Wu Daguan was 66 years old at that time. In 1982, he was transferred to the Science and Technology Appointed Standing Committee of China Aviation Industry Corporation and retired to the second line.


  In Wu Daguan’s 40-year first-line aviation career, he organized and developed five aero engines, only one of which was assembled on the plane after being finalized, but it was not mass-produced; And these five engines are all made by imitating and improving foreign engines. This is far from his original ideal of independent research and development-some conditions are hard to change in an era, such as weak basic industries and shortage of professionals … But Wu Daguan never flinched and worked tirelessly.


  Today, China is one of the five countries in the world that can independently develop aero-engines, which is closely related to the persistence of Wu Daguan and many older generation scientists.


  Everything revolves around work.


  Liang Yan, Wu Daguan’s granddaughter, is a outspoken girl. In Liang Yan’s memory, the place where her grandfather played with her as a child was usually confined to his office. While Liang was playing, Wu buried himself in his work and sometimes looked up, instilling the concept of "aerodynamics" in her. Therefore, in the late autumn of 1982, my grandfather and her memory of flying kites in the rice fields outside the compound of the Science and Technology Commission was particularly precious and unforgettable.


  At that time, Liang Yan felt that she had been playing for a long time, but she was definitely not satisfied. Before going home, she asked her grandfather when she would take her out to fly a kite again. Wu replied, "When grandpa stops working." In the end, this became an empty talk-it was not until 22 years later that Wu Daguan, 88, officially retired. At this time, Liang is no longer a little girl who cares about flying kites, and Wu is too old to run any longer.


  In these 22 years, Wu Daguan worked almost every day. His daughter Wu Xiaoyun described her father’s simple life track every day: going to work at seven o’clock in the morning, returning to the office immediately after dinner, and not coming home until nine o’clock or ten o’clock. "He always feels that time is not enough, always works overtime, and works and studies in the office on Saturdays and Sundays."


  Wu Daguan has his own considerations. He wants to do his best for the development of aero-engines in China. Although he has retired to the second line, "many comrades in the front line of information may not have time to read it, so I’ll look at it and sort it out".


  "In the Science and Technology Commission, an advantage is that you can access a lot of information. After learning about the development of foreign engines, I feel more and more backward." Wu Daguan elaborated in his autobiography "My China Heart".


  In 1983, he asked the Ministry to compile the specifications of China aero-engines. At that time, this proposal was considered by the design and process department as "putting a condom on your neck". However, Wu Daguan believes that he will do whatever is conducive to the development of China’s aviation power. He personally served as the editor-in-chief of the editorial board, leading and organizing the translation of the general specification for engines published in the United States at that time-5007d. Based on this, it took four years to compile the General Specification for Turbojet and Turbofan Engines and the General Specification for Turboprop and Turboshaft Engines, which are suitable for China’s national conditions, and then they were approved as national military standards.


  "Now these two standards are still in use, which is the starting point for China’s aero-engine scientific research to move towards standardization. Later, engines such as Kunlun and Taihang, which made Chinese people proud, were developed on the basis of this specification. " Shi Yuanguang, former member of the Standing Committee of the Science and Technology Commission, commented.
