Ingenious "Intelligent" China Good Machine Tool —— A Record of Ma Jianjun, a Worker Technician of Baoji Machine Tool Group

  "This bearing requirements are high. Look at the drawings, the design error here is only allowed to be 0.02 mm, so pay special attention. " At 8: 30 in the morning, Ma Jianjun exchanged technical research points with his disciples. Ma Jianjun is a key member of the machine tool performance laboratory of Baoji Machine Tool Group Co., Ltd. in Baoji High-tech Zone, Shaanxi Province. He has participated in the development and trial production of key new products and more than 30 major national special tasks, achieved more than 20 technological innovations, and successfully completed more than 50 major special machine tool commissioning, debugging and after-sales service tasks.

  Ma Jianjun graduated from Baoji Technical School. In July 1994, he came to the machining workshop of Baoji Machine Tool Factory and became an ordinary lathe operator. With only a degree of Chinese technical education, he suddenly felt unprecedented pressure in the face of high-precision processing equipment.

  "I just want to learn the technology well, study with the master during the day and go home for self-study at night." Technology, programming, electricity and cutting tools are the keys to the machining technology of CNC machine tools. Ma Jianjun uses his good foundation in turning technology to learn by doing and learn by doing. When he meets problems he doesn’t understand, he asks the master and inspectors, and takes time to check the information and take notes at night. After a few years, he wrote down more than 10 study notes and applied them to well-known CNC systems freely. Ma Jianjun once won the title of "Excellent Player" in the "Qinchuan Cup" first skill competition for employees of state-owned enterprises in Shaanxi Province, and participated in many national, provincial and municipal vocational skills competitions as a referee or technical director. Since 2010, he has been awarded the "lathe technology demonstration post" by the group company, and in 2015, he became the backbone member of Tian Haorong’s national skill master (model worker innovation) studio.

  In 2012, during his four-month equipment technical service for a company in Wuxi, he overcame difficulties, fulfilled his duties dutifully, and successfully completed the assignment abroad. In recent years, the company has successively ordered more than 100 machine tools from the company.

  In 2015, the key contract delivery of a company in Chongqing was just around the corner. Due to the tight time and high technical requirements, the company leaders are very anxious. Ma Jianjun took the initiative to take this "hard bone." He "nailed" the user’s trial production site for more than ten hours in a row, worked overtime to carefully study and ponder over each equipment, compiled the processing route program diagram, made corresponding fixtures and configured appropriate tools, and finally completed the dispatching and commissioning tasks of 14 CNC machine tools.

  Since 2014, Ma Jianjun has participated in a number of major national R&D and trial-production tasks for high-end CNC machine tools. Especially during the national major special research project and working in the machine tool performance laboratory, he was processing BTGS12 spindle, pull rod and ON— When processing parts with high precision coefficient and small tolerance range, such as rollers and D-rings in 3VII, with superb business skills, the processed parts exceeded the precision required by the drawing process and successfully completed the production task.

  In addition, Ma Jianjun cooperated with the research group to overcome a number of technical difficulties and broke through a large number of key processing technologies of CNC machine tools. In undertaking the R&D and production of BM63150C precision CNC lathe project, he boldly innovated, optimized the oil return structure at the back end of the machine tool spindle, and eliminated the weak links that affected the reliability of the machine tool; Through numerous groping, adjusting cutting parameters and workpiece clamping methods, the hard turning process test was finally completed, and the product won the "Chun Yan Prize" in cmtba. He also successfully solved the key new product BMC— The technical problem of machining the parts of the clamping sleeve in the center of 500TV five-axis compound milling machine makes the company’s first five-axis CNC machine tool enter the high-end market.

  Ma Jianjun has more than two suggestions for minor reform and process improvement every year, and has completed more than 30 key technical projects with studio members. In 2016, his studio passed the acceptance of the national skill master studio, and won the award of "All-China Workers’ Innovation Studio Key Project Fund". Advanced practices and experiences were promoted and exchanged in Shaanxi Province, realizing the transition from ordinary operating workers to knowledge workers, and then growing into expert talents in the new era.

Hong Kong Film Awards Announced "One Warriors" Won Seven Awards

Last night, the 38th Hong Kong Film Awards was officially announced at the Hong Kong Cultural Center.

With 17 nominations, The Warriors won seven awards, namely, Best Film, Best Director, Best Screenplay, Best Photography, Best Editing, Best production designer and Best Fashion Design, and became the biggest winner.

Operation Red Sea, who received eight nominations, won only three technical awards: Best Action Guidance, Best Visual Effect and Best Sound Effect.

Dragon and Tiger Martial Master won the prize for the first time.

Reveal the deep human touch of Hong Kong movies

As a commendation award given by Hong Kong film professionals to Hong Kong filmmakers in the past year, the Golden Awards have always adhered to the tradition of mutual encouragement and support, and have a strong human touch.

Last night, the Academy Awards first paid tribute to the filmmakers who died in 2018, including Jin Yong, Lan Jieying, Lin Lingdong and Ji Chunhua, who came from various positions in the film industry.

Andy Lau made an opening speech on the stage, hoping that the vitality of Hong Kong films would last forever, and at the same time led to the song and dance performance "Blast", which is also the theme song of Stephen Chow’s "New king of comedy".

Subsequently, Daniel Wu, Feng Delun, Nicholas Tse and Li Canchen, starring in "New Special Police Man", came to the stage as the best visual effects award winners. This year is the 20th anniversary of the release of "The New Special Police Man", and the four people once again appeared together, which triggered a wave of Hong Kong film memories. Similarly, Ekin Cheng’s and Jordan chan’s combined performances are also full of Hong Kong film feelings.

There is a "professional spirit award" for the Golden Awards. Last year, it was awarded to Yang Ronglian and Jackie Chan, who have been in charge of tea for more than 30 years in the crew. The scene was very touching.

This year’s "Professional Spirit Award" was given to Liu Yun, a martial artist of the Dragon and Tiger. This is also the first time in history that a martial artist of the Dragon and Tiger has won the Golden Award.

"Dragon and Tiger Martial Arts Master" is a special type of work in Hong Kong movies, which refers to martial arts masters who specialize in filming. They practice martial arts and play thugs and minions in movies. It is common for them to be beaten and injured.

Liu Yun is 70 years old. In 1968, he joined the film circle as a dragon and tiger martial artist. He is the most important dragon and tiger martial artist in the history of Hong Kong movies. He worked with Jackie Chan and other kung fu stars and suffered numerous injuries. In the 1970s, humorous kung fu films were hot, and Liu Yun developed in front of the curtain with the stage name of "Fish Head Yun". In the 1990s, he returned to his original post as a Dragon and Tiger Martial Arts Master, and has been doing so ever since.

Last night, Liu Yun expressed the hardships of doing this job at the backstage meeting of the winners. When he was a dragon and tiger martial artist for the first time, he knocked his head on the ground and fainted. He woke up and continued filming.

This year’s Lifetime Achievement Award went to Xie Xian. Xie Xian, the 83-year-old father of Nicholas Tse, is the witness of Hong Kong entertainment circle for half a century. He was called "the fourth brother" by his peers because he ranked fourth at home, and starred in the movies "The Condor Heroes" and "The True Color of Heroes". When Xie Xian won the prize, the audience stood up and applauded him.

He said on the stage, "I am old. I have been in this business for more than 60 years. I am very happy to see you again. I hope everyone will be happy and healthy. I hope that I will shoot more good plays in the future and show them to you. "

"Warriors" won 7 awards.

Become the biggest winner

"Warriors" won a double harvest at the word-of-mouth box office in 2018 and was nominated for 17 Academy Awards, setting the best nomination record in the history of Academy Awards.

In the end, The Warriors won seven awards, including Best Film, Best Director, Best Screenplay, Best Photography, Best Editing, Best production designer and Best Fashion Design, and won 7 out of 17 awards, becoming the biggest winner of the night.

Yu Dong, the producer of "Warriors", said that he and Zhuang Wenqiang talked about the idea of "Warriors" when they collaborated on the first "Eavesdropping Storm", which lasted for 13 years. The original story outline was in 2006, and it took more than ten years to temper this story.

Zhuang Wenqiang himself won two awards, Best Director and Best Screenplay, at the Academy Awards last night. He was shortlisted for best director four times and won the first prize. He thanked his wife on the stage, "because she always thought my film was a success!" "

Operation Red Sea, who received eight nominations, finally won only three technical awards: Best Action Guidance, Best Visual Effect and Best Sound Effect.

Two award-winning films

It’s all about marginal people

This year, several films reflecting the theme of marginalized people won performance awards at the Academy Awards.

Fallen Man tells the story of two little people in Hong Kong.

Liang Changrong, a middle-aged man, was separated by injuries, and the young Filipino maid had to become a maid because of reality. The unexpected meeting of two strangers taught them how to face the four seasons of life.

Chen Xiaojuan, the director of Fallen Man, is also the winner of the best new director.

Although it is a work directed by a newcomer, The Fallen Man has a high degree of completion. It takes the daily life of the little people as the starting point and substitutes the audience’s emotions with daily warm pictures. It is a typical "little movie".

The film star said on the stage: "I am honored to receive this award from Louis Koo. It turns out that my acting is still very good. I want to thank the director Xiao Juan for her kindness and talent. She treated me like a child at the scene and thanked the producer Chen Guo. Without him, the play would not have been possible. Thanks to my boss for his financial support, so that I can shoot this play without receiving money. "

The best actress was won by Zeng Mei Hui Zi, who played "Sanfu". In her acceptance speech, she thanked Leslie Cheung. "In my heart, my brother gave me great encouragement, and I learned from him what’ the drama is bigger than the sky’."

Kara Wai won the Best Supporting Actress Award for Trish, which is the second time that she won the Best Supporting Actress Award at the Academy Awards, and it is also her fifth personal Academy Award.

Sister Hong said on the stage: "It can be said that I am an actor who supports the new director most in Hong Kong. There must be young people in Hong Kong movies. It doesn’t matter how much money an old man like me earns. If Hong Kong movies can blossom, I feel so happy because I am honored to participate."

"Trish" also contributed a best supporting actor, Foo Wa Yuen, who was nominated for the Academy Award for the first time.

He said excitedly: "I am a native of Hong Kong, and Hong Kong movies have accompanied me to grow up. I have witnessed Hong Kong movies shine, and I want to be an actor because of Hong Kong movies. Even if I have no achievements, I have persisted silently for many years. Thanks to the boss Louis Koo, it is not easy to find investment in this subject. " (Lu Fang)

Grab the fresh experience and experience the Guangzhou Automobile Ai ‘an model after the bid change.

On November 20th last year, at the Guangzhou Auto Show, "Guangzhou Automobile Ai ‘an" announced its independent operation and built a high-end technology brand in an all-round way. Subsequently, Gu Huinan, general manager of Guangzhou Automobile Aian, officially announced that the company had changed its name to "Guangzhou Automobile Aian New Energy Automobile Co., Ltd.", and "Guangzhou Automobile Aian" would be positioned as a high-end intelligent electric vehicle brand. At present, Guangzhou Automobile Ai ‘an has released the fourth new car of Ai ‘an family, Ai ‘an Y, and the careful audience should notice that Ai ‘an Y has replaced a brand-new logo.
Less than half a year later, on April 16th, the safety model of GAC Ai officially switched the brand-new LOGO and body logo, and the logo of a single model was updated by more than 20 places. At present, vehicles with brand-new logos have been mass-produced and come to the store one after another. Xiaobian also took the lead in going to the store to experience GAC Ai ‘an after the rebranding.

First of all, let’s look at the mature and stable GAC Aion S.
After the rebranding, the biggest change in the appearance of AION S cancels the previous closed grille shape, adopts a larger air inlet shape, and the front face lines are sharp and sharp. The chrome trim is connected with the T-shaped headlight group. The "cloud arrow" design is highly recognizable.
Guangzhou Automobile LOGO was cancelled at the rear, and Guangzhou Automobile Aian with the same brand name "AION" was added at the rear to replace Guangzhou Automobile Chuanqi, fully highlighting the exclusive logo of "Guangzhou Automobile Aian" brand and "AION" model family. (According to the shop assistant, the combination of AI and ON represents the arrival of love and intelligence at the same time, and the car has become a "smarter companion" in life.) Overall, the design of Guangzhou Automobile Aian S is mature and stable, but
It is worth mentioning that AION S has continued to dominate the list in recent months.
Pure electric
Compact car sales list! The cumulative total sales volume has reached 86,568 units, and it is also the first pure electric vehicle to enter the TOP 10 sales volume of China brand cars.
The world’s first 5G car-ean AINO V
The appearance continues the family brand design, and the front face of the "Mecha Beast" highlights the sense of science and technology. The light group of the "Mecha Beast" adopts the eyebrow-eye combination of split structure and parametric grille, which is more recognizable and sci-fi. AION V makes the front face stand up by raising the chassis, which makes the overall visual effect even better. On the side, you can see that the chrome trim strips extend from the headlights to the C-pillar, and the three-dimensional waistline design makes the car look dynamic.
In configuration, AION V is equipped with China’s first integrated 5G+C-V2X vehicle intelligent communication system independently developed by GAC Ai ‘an. It is equipped with Huawei’s new generation 5G vehicle module MH5000, which has three advantages: high speed, low delay and wide connection. The dual 12.3-inch large screen, a million-level GEP 2.0 all-aluminum pure electric platform are safer, and there is an "intelligent remote parking" function that allows you to park in and out, and it is equipped with high precision. You can free your hands under the permission of regulations.
The vehicle has a total of 500 km and 600 km (NEDC working condition).
mileage
Version, in general, Guangzhou Automobile Ai ‘an AINO V has a long space and is rich in technology configuration.
Young people’s choice-Guangzhou Automobile Aian AINO Y
This time, I also saw the Guangzhou Automobile Aian AINO Y officially listed at the Shanghai Auto Show. In appearance, AION Y used the world’s first design concept of Sky City. The overall shape is simple and clear, but it has a strong sense of hierarchy. The front of the car is equipped with headlights that look like "Angel Wings".It has a high degree of recognition.
Perhaps because of the chrome trim on the front of the car, the logo seems to be bolder than its three brothers (AINO S, AINO V, AINO LX)! The logo is directly hollowed out in the middle, which further highlights the logo.The "G" and the inner ring are matched with a bright "AION blue" tone.In terms of body size, the length, width and height of AION Y are 4410/1870/1645mm respectively, and because the new car adopts the design of "four wheels and four corners", the wheelbase reaches 2750 mm.
The tail shape is full and simple.Dot matrix LED taillight matchingThe hollowed-out tail can add a hint of sports to the rear of the car. The design of line cutting can also form a good echo with the design of front face.
AION Y’s overall interior design belongs to a relatively simple style, and the center console uses a lot of straight lines, giving people a very comfortable feeling. The materials used in the work are also very particular, which can bring a good texture. The "G" LOGO on the steering wheel is replaced by the word "AION", and some details are decorated with contrasting colors. In addition, AION Y also provides a variety of spatial layout design, for example, after the front seats are completely flat, it can be transformed into a 1.8m double bed room. As long as you buy a projector+curtain, you can become a private small cinema, which is really practical in the self-driving journey. In addition,AION Y is also equipped with ADiGO 2.0 automatic driving assistance system, which can greatly reduce the fatigue of long-distance driving.
Although AION Y’s body size is not large, but inside the car,Excellent performance in space.In particular, there is plenty of legroom in the back row. What deserves praise is the endurance of AION Y. Before that, the first electric network had a endurance test, and the model with a cruising range of 600km ran 510 km on the road combining high-speed and urban areas under the condition of driving an air-conditioned car with two passengers!
From the appearance of the car body, the front part of the safety department of Guangzhou Automobile Company, compared with the original "G" LOGO, the brand-new "G" logo adopts a smart, flat and lightweight design, which is more conducive to the spread of the Internet, and this bid change is also more conducive to the younger generation, thus achieving the purpose of marketing.At the same time, it also marks another milestone step for GAC Ai ‘an after its brand independence.
Since its establishment in July 2017, GAC Aian has always adhered to the guidance of scientific and technological innovation, bringing good products and services to users, and the advanced, fun, trendy and high-quality brand genes have gradually taken root in people’s hearts.
Nowadays, Guangzhou Automobile Ai ‘an, which is positioned as a high-end smart electric vehicle brand, has also initiated comprehensive innovation and change from five dimensions: R&D, intellectual creation, industrial chain, marketing service model and organizational culture.
Facing the future, GAC Aeon will continue to evolve.
Finally, I remembered Xiao Yong, deputy general manager of Guangzhou Automobile Ai ‘an, who said, "In fact, those who do company development will find out in the end that they still take customer demand as the only focus and leave a mark on customers’ minds.".
Now, after the rebranding, Ai ‘an will show the exclusive logo of the "AION" family to the users at all times, as if it is sworn that Guangzhou Automobile Ai ‘an will start a new journey and forge ahead!

I know you are "watching".

Chery Tiggo 8L is listed! From 129,900 yuan, 2.0T+8AT is standard.

Editor of this article:

Write in front:This article is an original manuscript of Cheze, please indicate the source "Cheze" for reprinting, please do not infringe.

Enter the text:

On August 8th, Chery was officially listed. The new car is positioned as a medium-sized fuel SUV, which belongs to a higher-quality version of Chery. The price range is 129,900 yuan-174,900 yuan, providing 5 seats and 7 seats. In which: the standard version is 129,900 yuan; The comfort version is139,900 yuan; Deluxe edition is 149,900 yuan; The distinguished edition is 159,900 yuan; The 7-seat ring tower champion edition is 174,900 yuan. In short, it will be slightly lower than the pre-sale price. The highlight is the policy strength: the replacement enjoys a cash discount of 15,000 yuan, and the women’s volleyball guardian fund enjoys a cash discount of 10,000 yuan. The first car owner and used car enjoy a lifetime warranty.

Key point: Used cars are also guaranteed for life.

As for why he chose to push the fuel car again, Li Xue of Chery explained very hard: "It’s not that the fuel car can’t sell well, it’s that your fuel car can’t sell well."

As a reference, Chery sold 195,700 vehicles in July, up 30.1% year-on-year, and its overseas fuel export volume reached a peak. Chery believes that only by thoroughly understanding the basic skills of fuel can we get the highest score of new energy.

Chery has always adhered to the motivation of self-research. At the press conference, Li Xueyong also publicly stated that Chery is about to release a high-performance engine with an efficiency of 48%. What is the concept of 48%? At present, the highest I remember is about 46%.

Go back to the model itself. The model itself is the "top match" in the Tiggo 8 series, and its size configuration and performance are superior to those of the same family: Tiggo 8, Tiggo 8 PLUS and Tiggo 8 PRO.

The whole vehicle is built on the super hybrid platform of Chery Mars architecture and developed according to the global five-star safety standards, which meets both domestic and global requirements.

The whole vehicle is made of high-strength steel (85%) and hot-formed steel (21%), equipped with the only far-end airbag of the same class and 19 active safety configurations, reaching L2.5 intelligent driving assistance capabilities, such as rear cross collision braking, rear approach warning, lane keeping, lane departure assistance, blind zone monitoring, door opening warning, traffic sign recognition, front collision warning and automatic emergency braking, etc.

The dimension part has a length, width and height of 4795/1930/1741mm and a wheelbase of 2770mm, which is one circle larger than that of Tiggo 8 and is exactly the same as that of Tiggo 8. The seating layout is available in 5-seat and 7-seat (5+2) versions. The seats in the second row and the third row of the 7-seat version all support electric full flat down, and the official announcement can achieve a maximum capacity of 2065L!

The interior design is also highly referenced to Fengyun T9: equipped with 10.25-inch full LCD instrument panel, 15.6-inch central control screen, built-in Qualcomm 8155 chip, supporting Apple CarPlay+ Huawei HiCar.

The passenger seat is the "Queen’s seat" (zero gravity seat), which supports heating/ventilation/massage.

The new car is equipped with 2.0TGDI Kunpeng turbocharged engine, Miller cycle, second generation intelligent thermal management system, scissor double balance shaft and 350bar ultra-high pressure direct injection system. The advantage is that it is both fierce and fuel efficient.

The maximum power of the power system is 187 kW (254 HP) and the maximum torque is 390 Nm, which is almost equal to the performance of more than 600,000 2.0T engines (258 HP).

It is worth mentioning that this car matches the full-stack self-developed Kunpeng 8AT gearbox. At present, apart from Changan CS75 PLUS, few domestic cars within 200,000 yuan will be willing to use 8AT gearbox, which is generally dual clutch.

In terms of passability, the top gear provides the choice of four-wheel drive system. The four-wheel drive system has an intelligent control torque manager, which can realize the torque distribution of the front and rear axles, and provides three basic driving modes+four off-road modes, a total of seven driving modes.

Draw a key point: self-developed motivation, self-developed gearbox and self-developed four-wheel drive. Chery can be said that among domestic brands, it is rare for the three major fuel products to be so thoroughly researched and made by themselves.

Ok, the question is coming. Which version will you choose from so many versions?

Chang Shana: The Design Life of "Dunhuang Daughter"

  On the stage of the Spring Festival Evening in February 2024, the creative program "Nianjin" made a stunning appearance. Four performers were dressed in Hanfu in the Han, Tang, Song and Ming Dynasties. In front of the camera, traditional patterns, such as dogwood patterns, Swiss lion patterns, peony patterns, laurel patterns and gourd patterns, were exquisitely presented, showing a different artistic charm.

  this is93-year-old China contemporary arts and crafts artist, pattern scientist, art educator and designer Chang Shana.A newly completed work.

  During the preparation of the program, the director invited Chang Shana as an art consultant, and the design team extracted all kinds of patterns from historical materials, arranged them by hand, and finally Chang Shana made hand-painted modifications.

  "I am from Dunhuang, and my hometown is Dunhuang … …”Facing CCTV’s behind-the-scenes interview, Chang Shana said,"I like patterns very much. Every time I see them, it’s like seeing my old friends. I’ve been dealing with patterns all my life … …”

  Dunhuang is the theme of Chang Shana’s design life. She grew up in Dunhuang, constantly drawing design inspiration from Dunhuang elements and running all her life to promote Dunhuang art. She is called"Daughter of Dunhuang Art"In 2019, she wonChina Federation of Literary and Art CirclesLifelong achievement artist "honor.title.

  From Paris to Dunhuang

  There is a river in Lyon, France, called La Saone.

  In 1931, he studied at Lyon National Academy of Fine Arts.Chang ShuhongDecided to use the feminine French word Saone to name the newborn daughter, transliteration isShana.

In 1933, Chang Shana and his parents took a group photo in Paris.

  One day in the autumn of 1935, Chang Shuhong found a set on the old bookstall on the Seine.The six major editions of Dunhuang Grottoes are the French sinologist Bo.hopeAnd the book, which was filmed in Dunhuang Grottoes in China.More than 300 photos of murals and sculptures, the creation of which spans thousands of years.

  Chang Shuhong was shocked: "TheirThe brushwork is vigorous and powerful, the composition is magnificent and the characterization is vivid and powerful.His bold and unrestrained brushwork is even rougher than modern fauvism paintings … … "He later told Chang Shana that he had always admired European and Renaissance art, but he didn’t know it.The motherland has a thousand-year-old grotto art.He felt ashamed of it. From then on, he made up his mind to return to China to visit Dunhuang Grottoes.

  In August 1942,"the countryMember of the Preparatory Committee of Dunhuang Art Research InstituteWill "Established, Chang Shuhong as deputy director. He finally had the opportunity to go to Dunhuang in person.

  At the end of 1943, Chang Shana and his sister arrived in Dunhuang with their mother. Chang Shana went to visit in an ox cart."Thousand Buddha Cave" (hereinafter referred to as "Mogao Grottoes")She remembers that the sky was blue and the Daquan River in front of the Thousand Buddha Cave was frozen into a white glacier.

  As soon as she entered the hole, she was fascinated at once."Under the sunlight from the cave entrance, there are so many murals and colored sculptures that have never been seen before, which are overwhelming and colorful … …”

A family of three lives in the Mogao grottoes.

  The family lives in a room in the middle temple of the Thousand Buddha Cave. I ate the big pot rice in the canteen, and every meal must be accompanied by salt and vinegar to neutralize the local alkaline drinking water.

  In Dunhuang, Chang Shana got up early every day, practicing calligraphy first, then learning French, and asked Dong Xiwen to tutor Chinese and Western art history, and Su Yinghui to tutor China art history. At the request of her father, she went to the cave to copy murals every day, just like adults.

  "Dad asked me to start with objective copying and then take finishing copying as the standard.Visit all the key murals in the representative caves of the Northern Wei, Western Wei, Sui, Tang, Five Dynasties, Song and Yuan Dynasties.And understand the historical background of murals in copying, and accurately grasp the era style of murals in past dynasties. "Chang Shana said that she climbed into the cave on the centipede ladder every day, and when the morning sunlight came in directly, she lit up the colorful walls, and she began to paint cheerfully. In the desert, she practiced."I have no academic qualifications in the first stage of my artistic life.."

  "National, scientific and popular"

  From 1948 to 1950, Chang Shana was invited by Ye Lihua, a Canadian Jew, to study at the Art School of the Boston Museum of Art.. At the end of 1950, under the influence of progressive students studying in the United States, Chang Shana resolutely gave up his unfinished studies in the United States and returned home early.

  The first thing she did when she returned to China, she assisted her father, Chang Shuhong, and held a party on the Wumen Gate Tower in Beijing.Dunhuang Art Exhibition "In this exhibition, sheReceived Liang Sicheng and Lin Huiyin.After visiting the Dunhuang Art Exhibition, they decided to hire Chang Shana as the teaching assistant of the Arts and Crafts Teaching and Research Group of Tsinghua University Construction Department. It was also from then on that she embarked on the road of arts and crafts and art design.

Prepare for "Dunhuang Art Exhibition"

  In the construction department of Tsinghua University, Chang Shana accompanied Lin Huiyin to visit cloisonne, porcelain-burning and other craft factories that were on the verge of closure at that time.A number of novel patterns with national style and convenient production were designed..

  In 1952, the "Asia-Pacific Regional Peace Conference" was held in Beijing. Under the guidance of Lin Huiyin, Chang Shana designed a silk headscarf with the pattern of Dunhuang algae wells as a gift for delegates from various countries.

  In 1953, Chang Shana was transferred to the Department of Practical Fine Arts of the Central Academy of Fine Arts.In 1956, the Central Academy of Arts and Crafts (now Tsinghua University Academy of Fine Arts) was established and Chang Shana was transferred to the Department of Dyeing and Weaving.Teaching basic courses of pattern and dyeing and weaving design.

In 1996, Chang Shana delivered a speech at the "Art Design Exhibition of Central Academy of Arts and Crafts".

  From 1958 to 1959, in order to celebrate the 10th anniversary of the founding of New China, Premier Zhou Enlai personally directed the construction of "Top Ten Buildings" in Beijing, and the Great Hall of the People was one of them.

  "The Great Hall of the People will become the focus of political activities, which not only reflects the representatives of hundreds of millions of people discussing state affairs, but also reflects the form with China national style and the new content of building socialism under the leadership of the Communist Party of China after the founding of New China." Chang Shana recalled. Under the leadership of Lei Guiyuan, then vice president of the Central Academy of Arts and Crafts, sheParticipated in the whole process of architectural decoration design of the Great Hall of the People.. She upholds "Make the past serve the present and make foreign things serve China"Based on the design policy, combined with the consideration of structure, lighting, sound and other factors, after repeated deliberation, the design scheme of the dome light of the Great Hall of the People — — The dome light of the Great Hall, which accommodates 10,000 people, is centered on the red five-star and surrounded by radial sunflower petals, forming a group of dome light patterns symbolizing that "hundreds of millions of people are facing the light".

  Premier Zhou Enlai once suggested that the design of the Great Hall of the People should reflectThe principle of "national, scientific and popular". This has also become the artistic concept that Chang Shana pursues all his life..

  From 1983 to 1998, Chang Shana was the president of the Central Academy of Arts and Crafts.In 1994, she presided over the design.The Central People’s Government presented the Hong Kong Special Administrative Region with the commemorative sculpture "Forever Blooming Bauhinia". The sculpture should be "permanent, commemorative and artistic", which should not only reflect the meaning of the commemorative sculpture given by the central government, but also take into account the meaning and form that Hong Kong is willing to accept. Chang Shana recounted that in early 1997, she and her team made a field trip in Hong Kong and found that there were many bauhinia trees all over the street. "I was really excited to see bauhinia everywhere: bauhinia is the regional flower of Hong Kong, and isn’t it also a blooming bauhinia on the regional emblem of Hong Kong?" She took many photos of Bauhinia and drew many sketches, and the prototype of the sculpture scheme came into being. The design and production lasted for half a year, and the full-scale bauhinia sculpture with a height of 9.29 meters was completed. Chang Shana deeply touched:“‘Forever blooming bauhinia ’ It will stand permanently in the square of Hong Kong Convention and Exhibition Center and become a historical symbol and memorial of Hong Kong’s return to the motherland. From this, we can comfort our predecessors again. "

Commemorative sculpture "Forever Blooming Bauhinia"

  Don’t forget that you are from Dunhuang.

  Chang Shuhong once wrote to Chang Shana and said, "Shana, don’t forget that you are ‘ Dunhuang people ’ 。” She practiced this sentence all her life. She copied and created tens of thousands of Dunhuang art works and tirelessly publicized Dunhuang civilization to the world.

  In 1959, Chang Shana, Li Mianlu and Huang Nengfu used their summer vacation to go to the Mogao Grottoes to copy and sort out murals and colorful figures and costumes, and sorted them out altogether.Three hundred and twenty-eight color pictures. Limited by the conditions of the times, these materials were not published until 1986 and were namedDunhuang Costume Patterns of Past Dynasties.

  In 2003, Chang Shana, who had retired, went to Dunhuang with four graduate students and compiled and painted.Decorative Patterns of Dunhuang in China in Past DynastiesA book.

  In 2014, she began to holdThe world tour of "Blooming Dunhuang" shows and analyzes the pattern art of Dunhuang to people.Let Dunhuang elements enter a more popular world … …

  In 2019, Chang Shana wonChina Federation of Literary and Art CirclesLifelong achievement artist "Title, the award speech reads: "As the daughter of Dunhuang art, Chang Shana bears the change of the times of the organic combination of Dunhuang art research and modern art design with her special experience … …”

Chang Shana (second from right) won the honorary title of "Lifelong Achievement Artist" of China Federation of Literary and Art Circles.

They shook hands and took photos, and had a good talk. Chang Shana whispered a French sentence to Fan Jinshi: "C’est la vie. (This is life)." Two elderly people, who have been guarding the land of Dunhuang all their lives, said goodbye to each other.

In 2017, Chang Shana went to the warehouse of the French Ji Mei Museum and saw "The Image of Shana".

  My son Cui Donghui said that in the past two years, my mother’s life has slowed down. She gets up early every day, but she is no longer in a hurry, just sitting in a comfortable chair, reading, listening to the news and dozing off. When you rise, you still have to draw pictures, silently drawing some patterns of grottoes restoration, which are someThe pattern engraved in her mind..

  Occasionally, she will sing French nursery rhymes, as if recalling the deepest part of her memory. Dunhuang is the most frequently mentioned, and she and her son also said,The place I miss most in my life is Dunhuang..

A New Generation of Good Samaritan Tested 2013 Jetta 1.6L Automatic Transmission

speed up apply the brakes oil consumption second rice rise A New Generation of Good Samaritan Tested 2013 Jetta 1.6L Automatic Transmission Evaluation Editor-Liang Wei:

We have tested the new Santana before. Now I don’t know what to say about the new Jetta. Everyone is already familiar with every detail. I don’t know why, the performance test results of the new Jetta are much slower than that of the new Santana. Perhaps it is the differentiation treatment specially made by Volkswagen Group for the two products. We can only understand it this way. In addition, as an entry-level model, the new Jetta is still a little expensive, and some discounts will be more cost-effective, so we can wait.

Evaluation Editor-Hu Zhengyu:

Finally put the new Jetta to the test. The public has created such a large number of regular troops with uniformity and no personality to fight, and they are good at doing business.

Evaluation Editor-Luo Hao:

There is nothing to say to the same family of family cars. It won’t let you down, but it will never give you any surprises, that’s all.

Full text summary

  The landing of the New Deal in 2019 has brought new energy vehicles into the era of low subsidies. Many people predict that new vehicles will usher in a wave of price increases. However, through our visit, we found that the prices of new energy vehicles have not changed significantly, but the preferential margins of models in some regions have shrunk to varying degrees. Although Changan Automobile, BYD, and Great Wall Motor’s Euler brand have issued insurance plans, the time span is not long; Chery Automobile raises the guide price by releasing new year models. This "price increase" method is more clever and easier for consumers to accept.

  It has been more than a week since the New Deal was launched, and most new energy vehicle companies have not announced their new sales strategies. After all, not every company wants to pay for the subsidy. What are these car companies waiting for? It may be the competitor’s action, and the latecomers can better find the balance between sales and profits. In the cold winter of the automobile market and the transition period of new energy vehicles to marketization, price increases are no different from risks! Next, we will continue to investigate the terminal sales of some popular new energy vehicles and the implementation of official price protection measures, so stay tuned.
