As Geely Automobile has high hopes in the field of hybrid SUV, Geely Galaxy L is also positioning a new generation of intelligent electric hybrid SUV. In this car, Geely has invested in a series of heavy self-developed cutting-edge technologies such as "New Generation Raytheon Electric Hybrid 8848 Power System, Aegis Battery Safety System, Native Intelligent Cockpit System Galaxy NOS, Xingrui Intelligent Computing Center", and finally achieved 6.9s zero-hundred acceleration, WLTC5.23L/100km (NEDC4.4L/100km) power loss fuel consumption, 1370km comprehensive battery life and other data performance.

In order to differentiate the advantages, the Aegis battery safety system equipped with all Geely Galaxy L7 series can be used from the battery cell acupuncture "no smoke, no fire, no explosion" to the hard core "chassis armor" of the whole vehicle, from the cloud "super computing power support of the star smart computing center" to the radiation protection system that goes deep into the cell level of the whole vehicle, so as to achieve a 7X24-hour all-round security guarantee.

On July 3, the 10,000th Geely Galaxy L7 rolled off the assembly line. It is reported that among the first month car buyers of Geely Galaxy L7, the post-70s, the post-80s and the post-90s all accounted for the proportion. Among them, the post-90s accounted for the largest proportion, 50.93%. The proportion of users who purchased the high-end and top-end versions of Geely Galaxy L7 was particularly prominent, with 90.5% of users choosing the 115kmMAX and 115km starship versions.

According to the official, in the third quarter of this year, another smart electric hybrid car product of Geely Galaxy, Geely Galaxy L6, will also be launched. Born in February this year, Geely Galaxy will play an important role in the upward value of Geely and is also a new starting point for intelligent electrification. In the next two years, Galaxy will launch 7 new products, including the smart electric hybrid L series and the smart electric E series. The smart electric hybrid L series focuses on long-life PHEVs, using Geely Galaxy’s intelligent "electric hybrid" architecture, covering A0 to B-level intelligent electric hybrid products. The smart electric E series covers A-level to D-level intelligent pure electric products, impacting the mid-to-high-end market of 20-300,000 yuan. In addition to the already unveiled first electric hybrid SUV Galaxy L7 and the first electric hybrid sedan Galaxy L6, the other three new cars belong to the intelligent pure electric E series. The first pure electric product E8 will be delivered in the fourth quarter of this year, and other models will be launched one after another after 2024. New products will add new growth potential, and Galaxy will surely open a new curve of Geely’s market growth.

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.

Ren Xianqi bounces up Dongbula’s "One Earth" and re-walks the ancient Silk Road


Ren Xianqi

    On the 9th, the travel special "One Earth" held a media luncheon and press conference in Hong Kong. The star Ren Xianqi attended to share his experience with everyone, and also performed noodles in person. It is reported that the film focuses on the history, scenery and humanities along the Silk Road, so as to promote the ancient Silk Road. In the film, Ren Xianqi drives an off-road motorcycle to embark on an expedition to re-walk the Silk Road, from Shaanxi to Gansu to Xinjiang. Ren Xianqi also specially donned the Xinjiang flower hat "Dopa" and played the national musical instrument "Dongbula" at the scene, which is quite ethnic.

    Ren Xianqi said that the next time he wants to challenge some ridiculous things that he did not dare to do in his later life, "I will circle around Taiwan next year, and I will participate in the Xinjun Island Cross-Country Desert Endurance Race in September next year. It will be more difficult than I imagined. It is more than 5,000 kilometers long and has passed through the desert terrain. I have already started to exercise." Recently, due to the heavy snowstorm in Inner Mongolia, he also started to shoot "Women of Yang Gate" on Christmas Day. Xiao Qi said: "Our work is not a natural calculation. We stayed at home to accompany our family at Christmas. I also went to buy a Christmas tree. As a result, I was filming in Inner Mongolia in the past two weeks, but Inner Mongolia just encountered a blizzard, and the temperature dropped to more than 40 degrees. Shooting our city gate, the scene blew down." It is reported that in addition to having a rival role with Cecilia Cheung, there are about 50 actresses in the whole film, which can be described as "endless happiness." (Photo and text/Tungstar)

Binding China enterprise ZF to automatic parking on a large scale

  [car home Industry] When people talk about ZF, they must have a high evaluation of its 8AT gearbox. There are countless partners in this star product, especially BMW, which is famous for its control. Most of its models use ZF 8AT gearbox. Today, ZF will no longer be a simple gearbox company, but will gradually evolve into a technology company focusing on the future travel field.

  "Before 2030, ZF’s contribution to the Asia-Pacific region needs to reach 30% of the group’s income, and the China market will become the main source of growth to achieve this goal." At the strategic cooperation ceremony between ZF and China technology company Tiantong Weishi on June 15th, Dr.Holger Klein, director of ZF Group, said, "This requires us to cooperate with forward-looking partners in the local ecosystem of China."

Why did you choose Tianqi Weiwei?

  On June 15th, ZF signed a strategic cooperation agreement with CalmCar to jointly develop cost-effective automatic parking (APA) and automatic parking service (AVP) systems. At the same time, this is the first time that ZF has invested in a local start-up technology company in China.

  In Ke Haozhe’s view, it is now in an era full of challenges and changes. On the one hand, the travel industry is facing common challenges such as COVID-19 epidemic, chip trade and climate change; On the other hand, software-defined cars, as well as the development of technologies such as autonomous driving, artificial intelligence and 5G, will combine the digital world in the field of travel with the real world. These common challenges and opportunities are complex and interrelated, and ZF should cooperate with upstream suppliers, first-class suppliers and automobile manufacturers.

"Ke Haozhe, Director of ZF Group"

  In recent years, by actively participating in the domestic ecological circle, ZF has actively deployed its work focus and company resources in the high-tech development of China, and taking a stake in Tiantong Weishi is a major move of ZF. "This year coincides with the 40th year of ZF’s operation in China. At this key node, ZF participates in the China automobile ecosystem and has deeper cooperation with China start-ups. This is also an important performance of the Group’s emphasis on the China market. " Ke Yuzhe said.

  ZF has made some achievements in the key technical fields of automatic driving, from high-precision sensors and intelligent actuators to high-efficiency on-board central computers and service-oriented software systems. Perhaps the outside world will ask, start-ups are overwhelming, why did ZF choose Tianqi Weiwei?

Home of the car

  Xing Xun, Engineering Director of China Electronics and Driver Assistance System Division of ZF Group, said, "As early as 2017, ZF cooperated with Tianzhu, and now the technical achievements of our cooperation have been verified in 3-4 years. This also means that this technology is reliable. "

  "ZF is not willing to invest in a company if it is only famous, rather than the two sides spend time and energy on joint development. This is a starting point for ZF to cooperate with start-ups in China-it takes some time and technical precipitation. " Xing Xun added.

  At the same time, Damon, founder and CEO of Tiantong Weishi, predicted that in 2023, L2-class and L3-class advanced assisted driving will achieve large-scale development in the China market, and in 2025, China will usher in large-scale mass production of L4-class autonomous driving. Compared with the global OEM layout, China will be two years ahead, among which low-speed assisted autonomous driving has completed 35% assembly rate in 2020.

  ZF and Tiantong Weishi have come a long way, and now is the right time to strengthen and deepen cooperation.

AVP system landed in China on a large scale?

  "The automatic parking system, whether it is the end consumer or the OEM, has a very strong demand for this function." Asked why ZF laid out the AVP field, Xing Xun said, "Aiming at the problem of parking difficulty, automatic parking service is a product that really comes from the demand side."

  ZF will start with automatic parking and automatic parking service, and build future-oriented autonomous driving technology to support the next generation of travel modes. If we look back at the Shanghai Auto Show in April this year, ZF released AVP automatic parking service technology for the first time. In fact, this technology is based on the deep cooperation between the two parties.

  ZF’s specialty in sensor actuators and system integration, combined with the software support of Tiantong Weishi and the crowdsourcing map technology of another partner, this AVP automatic parking service technology can provide an economical and efficient solution for car companies without relying on the transformation of parking lot infrastructure and the prefabrication of high-precision maps of parking lots.

  "Actually, ZF has a relatively comprehensive layout in L2-level assisted autonomous driving and L4-level autonomous driving on highways. Comparatively speaking, there are shortcomings in the low-speed automatic parking scene." Xing Xun said frankly, "In this field, the working conditions in China are very different from those in foreign countries, including the parking environment and garage construction methods. Cooperation with Tianzhu Weishi is essentially a supplement and improvement to ZF’s construction of autonomous driving map. "

  Just as the technical route of self-driving cars is divided into bicycle intelligence and vehicle-road coordination, automatic parking service also has two major routes: vehicle end and field end. It is reported that the AVP system jointly developed by ZF and Tianzhu is mainly based on vehicle intelligence.

  The automatic parking service system is equipped with four fisheye cameras with a panoramic view of 192. By using the fusion of 360 panoramic view perception of Tiantong Weishi and ultrasonic radar perception, the system can effectively identify parking spaces and obstacles, help vehicles locate indoors and outdoors, and plan automatic parking paths in real time.

  "There are 400,000 paid parking lots in China. If we carry out large-scale field-side renovation, it is actually unrealistic. Therefore, Tianzhu Weishi uses its own unique algorithm advantages and combines ZF’s century-old experience to realize automatic parking service without increasing the cost of the vehicle on a large scale. " Damon, founder and CEO of Tianzhu Weishi, stressed, "Only in this way can the AVP system land quickly and on a large scale."

  It is understood that ZF AVP system is scheduled to be installed for the first time on the models of China automobile manufacturers at the end of 2022, and the landing scenes are airports, shopping malls and parking lots.

Meet the new challenges of China market

  "The cooperation between ZF and Tiantong Weishi is a good start, but such cooperation is definitely not the only cooperation of ZF. We will conduct a very profound and comprehensive investigation in the future to find a partner that complements ZF in culture and technology in the automobile ecosystem, making the overall business model of the group more flexible." Wang Runyi said, "This is our goal, and ZF will carefully and openly choose China partners."

  2021 is the 40th year that ZF entered China. In these 40 years, ZF has witnessed the rapid development of China automobile industry. From 1981, ZF received its first order in China, to 1994, ZF opened its first factory in Langfang, and now, ZF has nearly 50 manufacturing enterprises and three R&D centers in China. ZF has gone through the process from "sales in China" to "manufacturing in China" and then to "R&D in China".

  It is worth mentioning that ZF’s sales in China increased by 10.3% in 2020, which is at the same level as that in its home market. In the past two years, as a Tier1 supplier, ZF found that the demand of China OEM changed greatly.

  "First of all, the OEM’s own research and development capabilities have been significantly improved; Secondly, the technology and services provided by the main engine factory to suppliers need to be faster in response speed; Finally, it is more flexible in technical requirements, and tends to combine the specific needs of OEMs, with a more systematic and deeper understanding. " Wang Runyi told car home.

  "In the past, a new model was developed for three or four years. This era no longer exists. What we see is the average aging of 6-18 months. This puts higher demands on ZF’s R&D team. " Wang Runyi believes that ZF needs the help of local start-ups in China to respond to customers’ requirements quickly.

Home of the car

  In fact, at the technical level, the supply mode of black box or white box in the past can no longer meet the needs of OEMs. "OEMs hope that ZF can help tailor the architecture based on them and make technical synthesis according to customer needs." Wang Runyi said.

  For example, the cooperation between ZF and Tiantong Weishi not only speeds up the R&D process of ZF localization, but also shortens the technology R&D cycle, accelerates the technology iteration speed, and enables the latest technology to be put into the market better and faster. By strengthening technical exchanges, the two sides will jointly build a new platform with complementary advantages and win-win cooperation.

  As Wang Runyi said, "China is the top priority of ZF’s future development strategy. We will continue to increase investment in China, welcome the deepening exchanges between partners inside and outside the industry with an open mind, look forward to the future together, and explore different cooperation modes. Qi Xin will work together to turn challenges into opportunities, which will make it impossible and possible."

■ Editor’s summary:

  In addition to the automatic parking service technology launched this time, ZF has continuously expanded its business boundaries in recent years, focusing on the "next generation travel" strategy. For example, the establishment of the electric drive technology division, the integration with the commercial vehicle technology company Webeco, the sales of independent software solutions and the establishment of a brand-new software center. There are no enterprises that are always successful, only enterprises that constantly adapt to the general trend of the times. (Text/car home Peng Fei)

From online celebrity’s counterattack to actor, Fei Qiming did it.

Wenbailu

Editor Bailu

Recently, Qi Song, the "assassin in the workplace" in "20 Don’t Confuse 2", made frequent comments on the Internet, and was evaluated by the audience as "everyone’s Internet mouth replacement".

 

Qi Song (Fei Qiming) is smart, creative, romantic and gentle, and warms the person he likes like a little sun, with 100% healing power!

At work, he is an anti-anxiety and anti-involution person.

 

When the project encounters problems, Qi Song will not keep working overtime to put pressure on himself like ordinary people, but will open up new ideas for himself by entertainment.

When the project was completed, but the leader stepped in to grab the work, Qi Song dared to resist the angry leader.

 

In feelings, he is a walking generator.

 

Qi Song and Xiao Guo (Guanjin Bu) look at each other in the power-off office. It’s hard not to be moved by this atmosphere!

Although on the surface, they always quarrel and play like chickens in primary school, in fact, Qi Song has a crush on Jiang Xiaoguo (Guanjin Bu) since high school. When I was in college, I went abroad for further study. After becoming more independent and excellent, I returned to Xiaoguo to provide her with energy.

 

Xiaoguo introduced his name as "small" and "fruit" of fruit.

Qi Song said that it was the other mountains all appear dwarfs under the sky.’s "small" and fruitful "fruit".

This is the so-called "beauty is in the eye of the beholder" ~

 

Xiao Guo’s speech after drinking for a long time was recorded by a willing heart and sent to the company group for "public punishment". Qi Song will immediately use the expression pack to screen the screen to ease her embarrassment.

 

When two people encounter difficulties in a cooperative project, he always tries his best to solve them and become the most solid back of Xiaoguo.

I can not only fight with her, but also struggle with her. When I get along, I am a happy maker. At the critical moment, I am the best partner who is calm and reliable. Please give me a dozen of this kind of boyfriends!

 

Qi Song’s anti-involution and anti-anxiety "workplace assassin" is rare in domestic workplace dramas, and his debut experience as a player, Fei Qiming, is like an "assassin" and unique in the entertainment industry.

 

In 2017, several ten-second videos made Fei Qiming, who was still in college, become the first generation of online celebrity in Tik Tok, and created a unique school grass style with gold-rimmed glasses and boyish smile. However, in the booming era of short videos, Fei Qiming has set his sights on the entertainment industry.

In 2018, Fei Qiming began to "de-online celebrity" and participated in the popular variety "Happy Camp". His popularity on the Internet remained high, and his road to transformation officially began.

 

In the same year, he received an invitation to audition for the school play "I am waiting for you in the future" and partnered with Qian Sun, Xin Yunlai and other new generation actors. In the play, he plays Liu Dazhi, an optimistic boy, who not only won the recognition of Li Guangjie, an old opera player, for his courage of being a newborn calf, but also reversed the questioning voice before the broadcast because of his natural performance and true feelings. This is the first step in his transformation from online celebrity to an actor.

 

But because I devoted myself to filming and didn’t update Tik Tok for a long time, I lost a big wave of fans. For the gains and losses, Fei Qiming is very calm: "I hope I can sink and be seen when I look up."

 

However, the popularity of a drama series didn’t make him completely get rid of the label of Tik Tok online celebrity. What really made Fei Qiming break through was various popular variety shows.

 

From his debut in 2018 to the present, Fei Qiming has won a total of 8 variety shows. Among them, Iqiyi’s parent-child reality show "Super Kindergarten", RV travel reality show "Flower Road of Youth", Tencent’s video beauty program "Prince Lipstick", and now the popular variety "Fifty Kilometers of Peach Blossom House" and other variety shows have his figure.

 

Now, he not only proved his talent and hard work in performance again in "Twenty Don’t Confuse 2", but also a large wave of dramas to be broadcast filled the audience’s expectations.

 

For example, the sci-fi drama Orphan of Mars, adapted from the novel of the same name by science fiction writer Liu Yang, in which Fei Qiming plays the man Guhe.

Although his debut is only four years, and there are only a handful of film and television works, Fei Qiming, who was born in online celebrity, is full of love for acting. When talking about the career of actors, he said that "actors only have a starting point and no end point; The sense of crisis as an actor is everywhere. "

 

There are many people who want to lose weight, but very few people can really reinvent themselves. Fei Qiming is one of them. At the age of 17, Fei Qiming was a little fat man weighing nearly 200 Jin. However, in a few years, he turned into a sunny male god on the university campus. After entering the entertainment industry, he set up a special area at home to study scripts and feel the lives of different roles in order to hone his acting skills.

In line with the image of "little sun in the workplace" on the screen, he is also a versatile big boy in reality.

Not only is he proficient in playing and singing, but he also writes well. A little brother who is handsome and can sing and act ~

From the figure counterattack to the transformation actor, his dedication perfectly explains that down-to-earth talents can accumulate thick hair. I believe that Fei Qiming in the future will make constant progress and realize his dream of "becoming a good actor".

Electric car battery, electric car battery is dry battery or lithium battery?

1. Is the battery of electric vehicle a dry battery or a lithium battery?

Dry batteries are generally lead-acid batteries. With the same capacity and voltage, the weight of lead-acid battery is three times that of lithium battery. Lead-acid batteries also have a short life. Current lead-acid batteries can’t go far in two years, while lithium batteries can last for five years. Due to its own weight, the battery life is incomparable to that of lithium batteries. But dry batteries are cheaper. It depends on how you choose. What suits you is a good lithium battery electric car: advantages: high efficiency. The car body is light, the mileage is long, and the requirements for the use and maintenance of users are not strict. Disadvantages: the price is high, and the domestic lithium battery technology is uneven, and the lithium battery used for electric vehicles has potential safety hazards. Lead-acid battery electric vehicle: advantages: high cost performance. The battery is relatively cheap, with large capacity, many battery brands and mature technology. Disadvantages: the efficiency is not very high. The battery pack is bulky, resulting in a heavy body and short mileage, so it is necessary to maintain the battery regularly.

2. Is dry battery or lead-acid battery better for electric vehicles?

Electric bicycles and motorcycles have become important means of transportation in large, medium and small cities and are generally accepted by people. Compared with traditional bicycles, the price of electric bicycles is generally higher, so the service life has become the most concerned issue. In fact, the battery is one of the core components of the electric bicycle, and the service life of the battery largely determines the service life of the electric bicycle. In this regard, Chaowei Battery said that strengthening the maintenance of the battery will extend the service life of the battery. It is understood that the batteries used in electric vehicles are lead-acid batteries! Dry batteries are a scam! In addition, I will send you a message: the starting current of electric vehicles is very large, especially for electric motorcycles with high-power motors. Heavy current will damage the battery plate. The best way is to start the power supply after riding the electric car like riding a bicycle. After the battery is used for a period of time, some active substances will inevitably settle. If the active substance is not activated in time, it will definitely affect the capacity of the battery. Deep discharge the battery once. Judging from the current use of electric vehicle batteries, lead-acid batteries are mature in technology, cheap in price and stable in performance. The dry battery of electric vehicle is mainly lithium battery, which is twice as expensive as lead-acid battery, but its service life is longer than that of lead-acid battery, but with the increase of charging times, its service life will become shorter and shorter. For example, lead-acid batteries need to be replaced once a year, and lithium batteries can be replaced once every two years, but lead-acid batteries can be replaced once a year, and the cruising range of lithium batteries will be shortened in the second year, which will affect their use.Compare their respective prices, calculate the cost and your own usage, and see which is more cost-effective. I recommend lead-acid batteries. Dry batteries are easy to use, durable and small in size, but the price is a bit expensive. It is the future development. Lead-acid batteries will be out of stock. Use lead-acid batteries. The storage capacity is stronger. If you ride it every day, you’d better charge it every day. I know a lot of fake batteries, so it’s unnecessary, right?

3. Is lithium battery for electric vehicle really better than lead-acid battery?

Lead-acid batteries have the largest number. Lead-acid batteries are the cheapest and most commonly used. China is the largest producer of lead-acid batteries in the world. It contains less pollution components and has good recyclability. The disadvantage is that the specific volume is small. In other words, under the same capacity, the weight and volume of the battery are very large. At present, lead-acid batteries are basically developed from floating batteries. Floating battery is not suitable for fast charge and high current discharge. Although technicians have spent a lot of energy on effective improvement and can put it into practical use, its service life is still very long. Colloidal batteries belong to a development category of lead-acid batteries. The simplest method is to add gelling agent to sulfuric acid, so that sulfuric acid can be electrically liquefied into colloidal state. The battery with electro-hydraulic colloid state is usually called colloid battery. In a broad sense, the difference between colloidal battery and traditional lead-acid battery is not only that electro-hydraulic battery is changed into colloid. For example, non-condensed hydrocolloids belong to colloidal batteries in electrochemical classification structure and characteristics. Another example is that polymer materials are attached to the grid, commonly known as ceramic grid, which can also be regarded as the application characteristics of colloidal batteries. Recently, some laboratories have added targeted coupling agents to the polar plate formula, which greatly improved the reaction utilization rate of the polar plate active materials. According to unpublished data, its weight ratio can reach 70wh/kg. These are the current industrial practice and the application examples of colloidal batteries that will be industrialized soon. The difference between colloidal batteries and conventional lead-acid batteries is that from the initial understanding of electrolyte gelation to the study of electrochemical characteristics of electrolyte basic structure,Then to the application and promotion of grid and active materials. Its most important feature is to manufacture better batteries along the road of lead-acid battery industry for 150 years with relatively small industrial cost. Its discharge curve is flat and its inflection point is high, and its specific energy is 20 times larger than that of conventional lead-acid batteries. The battery of electric vehicle must choose lithium battery. Lead-acid batteries used in traditional electric vehicle batteries will produce a lot of pollution and lead vapor after being discarded. According to statistics, a batch of waste batteries of electric vehicles will pollute tens of thousands of tons of water. Lead is not easy to be excreted, and it can also cause diseases such as metabolism, reproduction and nerves. Once the lead content in the human body exceeds the standard, it will lead to mental decline, fetal malformation, and it is easy to induce malignant tumors in children and even lead to death. Compared with lead-acid batteries, lithium batteries have natural advantages in environmental protection. The materials used for lithium batteries do not contain harmful heavy metals such as cadmium, lead and mercury. In the process of production and use, lithium batteries do not produce any pollutants, which ensures human health. Solved the problems of water source and soil. In addition, lithium batteries also have the advantages of large specific energy, long cycle life, low self-discharge rate and no memory effect. The storage energy density of lithium batteries is high, which has reached 460-600wh/kg at present, which is about 6-7 times that of lead-acid batteries. The service life can reach more than 6 years, and the anode lithium iron phosphate battery can charge and discharge 1cdo. Can be used for 10,000 times; It has high power tolerance, and the Ferrous lithium phosphate lithium-ion battery used in electric vehicles can realize the charge and discharge capacity of 15-30c, which is convenient for high-intensity start acceleration;The self-discharge rate is extremely low, which is generally lower than 1% per month at present, less than 1/20 of that of Ni-MH battery; Lithium battery can completely meet the power requirements of electric vehicle batteries, and become an ideal product for electric vehicle applications because of its green and environmental protection characteristics. I hope it will help you.

4. Why are the batteries of electric vehicles all lead-acid batteries?

Of course not, because lead-acid batteries have the following characteristics and advantages: sealed structure, no acid leakage and no acid mist emission. One-way exhaust valve (also called safety valve), the function of this valve is that when the amount of gas inside the battery exceeds a certain value (usually expressed by air pressure value), that is, when the air pressure inside the battery rises to a certain value, the exhaust valve automatically opens, discharges gas, and then automatically closes the valve to prevent air from entering the battery. Compared with ordinary lead-acid batteries used in automobiles, valve-regulated lead-acid batteries have two main characteristics: one is sealing; The second is dry. Sealing means that there is basically no acid mist discharged. Generally, the VRLA battery is "zero emission" during its operation (charging and discharging), and only when the gas pressure in the battery exceeds the opening pressure of the safety valve in the later period of charging can a small amount of mixed gas of hydrogen and oxygen be discharged, and at this time, a small amount of acid mist is filtered out by a filter material. Dry state means that the VRLA battery has no free flowing electrolyte, and can be placed in any direction, not afraid of bumps and collisions, and no acid will leak out even if the shell is broken. During the use of lead-acid batteries, chemical energy is only continuously converted into electrical energy, and electrical energy is also converted into chemical energy, which is repeatedly circulated, thus causing "zero emission" to the external environment and no pollution to the environment, which you do not have with 40 No.5 batteries. 1. Electric vehicle batteries are not all lead-acid. Now there are many lithium-ion electric vehicle batteries, and most of them are composed of many small batteries. The adoption of lead-acid batteries is the result of many considerations such as production difficulty, cost and reliability.2. The basic feature of lead-acid battery is that it does not need to be maintained by adding acid and water during use. The battery has a sealed structure, which will not leak acid or discharge acid mist. The battery cover is equipped with a one-way exhaust valve (also called a safety valve), which is used to prevent air from entering the battery when the gas volume inside the battery exceeds a certain value (usually expressed by air pressure value), that is, when the air pressure inside the battery rises to a certain value, the exhaust valve will automatically open, exhaust gas and then automatically close the valve to prevent air from entering the battery. 3. Compared with ordinary lead-acid batteries used in automobiles, VRLA batteries have two main characteristics: one is sealing; The second is dry. 4. Sealing means basically no acid mist is discharged. Generally, the VRLA battery is "zero emission" during its operation (charging and discharging), and only when the gas pressure in the battery exceeds the opening pressure of the safety valve in the later period of charging can a small amount of mixed gas of hydrogen and oxygen be discharged, and at this time, a small amount of acid mist is filtered out by a filter material. 5. Dry state means that the VRLA battery has no free flowing electrolyte, and can be placed in any direction, without fear of bumps and collisions, and even if the shell is broken, there will be no acid leakage. 6. During the use of lead-acid batteries, chemical energy is only continuously converted into electrical energy, and electrical energy is also converted into chemical energy, which is "zero emission" to the external environment and will not cause pollution to the environment. One reason: cheap. If you change to a lithium battery, the battery will cost thousands ~ now it mainly depends on lead acid to store electricity and generate electricity, and there is no better material to replace it. Besides, this cost is low, which is suitable for the needs first! Not all batteries of electric vehicles are lead-acid.Now there are many lithium-ion electric vehicle batteries. Lithium-ion electric vehicle batteries. Most of them are also composed of many small batteries. The adoption of lead-acid batteries is the result of many considerations such as production difficulty, cost and reliability. Your scheme is feasible in theory, but just accumulating one item based on the quality difference between batteries makes your scheme useless. Not to mention cost and reliability.

5. What kinds of batteries are available for pure electric vehicles? There are two types of batteries for electric vehicles, storage batteries and fuel cells. Batteries are suitable for pure electric vehicles, including lead-acid batteries, nickel-cadmium batteries, nickel-hydrogen batteries, sodium-sulfur batteries, secondary lithium batteries and air batteries. Among them, lead-acid batteries, nickel-cadmium batteries and nickel-hydrogen batteries appeared earlier, and they are also the types of batteries that have been generally eliminated. Nowadays, the mainstream pure electric vehicles are basically lithium batteries, mainly including lithium cobalt oxide batteries, such as products; Lithium manganate batteries, such as (||) and Leaf Wind; Lithium iron phosphate batteries, such as products, (||), etc. Lead-acid battery is the most commonly used new energy vehicle battery. The polar plate of lead-acid battery is a grid made of lead alloy, the electrolyte is dilute sulfuric acid, and both polar plates are covered with lead sulfate. However, after charging, the lead sulfate on the electrode plate at the positive electrode is converted into lead dioxide, and the lead sulfate at the negative electrode is converted into metallic lead. When discharging, the chemical reaction in the opposite direction occurs. The advantage of lead-acid battery is that the electromotive force is stable when discharging, but the disadvantage is that the specific energy is small and it is corrosive to the environment. 1.

Nowadays, the mainstream pure electric vehicles are basically lithium batteries, mainly including lithium cobalt batteries, such as Tesla products;Lithium manganate batteries, such as Toyota Prius and Nissan Leaf; Lithium iron phosphate batteries, such as BYD products, 1E, etc. 3. Lead-acid battery is the most commonly used battery for new energy vehicles. The polar plate of lead-acid battery is a grid made of lead alloy, the electrolyte is dilute sulfuric acid, and both polar plates are covered with lead sulfate. However, after charging, lead sulfate on the electrode plate at the positive electrode is converted into lead dioxide. 4. Lead sulfate at the negative electrode is converted into metallic lead. When discharging, the chemical reaction in the opposite direction occurs. The advantage of lead-acid battery is that the electromotive force is stable when discharging, but the disadvantage is that the specific energy is small and it is corrosive to the environment. For the time being, there are only experimental products for sodium-sulfur batteries for vehicles. 1. There are many kinds of fuel cells, such as hydrogen fuel cells, high-temperature fuel cells, direct methanol fuel cells, methanol reforming hydrogen fuel cells, metal fuel cells and so on. 2. At present, hydrogen fuel cells are the mainstream in the field of passenger cars, and Toyota is the representative factory. The biggest feature is that it can achieve pollution-free throughout the life cycle (from the beginning of raw material manufacturing to the final recycling). 3. The fuel hydrogen used has the characteristics of high energy density and zero pollution. The disadvantage is that the current cost is very high, and the volume power density is limited. Take the representative of the fuel cell vehicle (||) as an example, the volume of the fuel cell system of NO is roughly equivalent to a V6 engine, but the output power is only in the early 100KW, which is about 140 horsepower. The price of the whole vehicle is roughly equivalent to 338 horsepower. In fact, these two kinds of batteries can be said to have their own advantages. At present, lithium iron phosphate batteries are used a little more, because Ferrous lithium phosphate has good cycle stability.The cost is also relatively low. However, the consistency of Ferrous lithium phosphate is not as good as that of ternary battery, and there are still many problems in material stability, safety and processing technology. The specific landlord can check again, and the relevant information is still quite a lot. Personally, I recommend ternary batteries. At present, Ferrous lithium phosphate and ternary batteries are the main ones, and lithium manganate can be ignored. Take our car as an example. ev160 uses lithium iron phosphate battery, which is ternary lithium battery. Ferrous lithium phosphate’s technology is more perfect, but its future development is not as good as ternary lithium. I bought ev160, so I recommend Ferrous lithium phosphate, and I will buy ternary lithium car when ternary lithium technology is mature. Land Ark brought its newly listed pure electric vehicle v5s at the 2015 Energy Saving and New Energy Auto Show. The car was launched on October 15th, 2015, and it is the upgraded version of the first pure electric v5 launched by Land Ark in 2013. According to the staff, the car has a battery life of 150 kilometers and the price is about 75,000 yuan. Compared with lithium iron phosphate battery, ternary lithium battery has several improvements: power increase, energy density increase, charging rate increase, good low-temperature performance, and battery cells are combined and packaged. But lithium ternary is more unstable than Ferrous lithium phosphate, so the good and bad are 50% and 50% respectively.

Xinhua All Media+What’s the Five Ones? Let’s see how the most beautiful workers are tempered.

  Xinhua News Agency, Beijing, April 30th Question: this five "one" depends on how the most beautiful workers are tempered.

  Xinhua news agency reporter

  Labor creates happiness, and strives to write Chinese chapter. In the arena of life, they carry the pursuit of a better future with small tools, and interpret and carry forward the spirit of model workers, labor spirit and craftsman spirit with wisdom and sweat. On the eve of May Day, the reporter approached five of the most beautiful laborers and listened to their initial stories of forging the "most beautiful".

  A notebook computer: releasing the potential of labor creation

  "I am lucky to be able to release my labor enthusiasm and creative potential in China’s space industry." When the reporter saw the 23-year-old Hu Xingsheng next to the CNC machine tool of the No.283 Factory of the Second Academy of Aerospace Science and Technology in China, he had just won this year’s National May 1 Labor Medal.

  In addition to using traditional old pliers, bolts and wrenches, maintenance workers who maintain CNC machine tools rely more on a notebook computer to troubleshoot port and signal failures.

  Hu Xingsheng checks faults at work. (Photo courtesy of the interviewee)

  The operation of CNC machine tools requires high precision. In the aspects of geometric accuracy inspection and geometric accuracy compensation, he and his colleagues have conducted thousands of drills to make the machine tool operation more accurate to meet the requirements of workpiece production. Not only that, but in more than a year, he also developed a number of equipment.

  One of the automatic grinding devices for graphite casing breaks through the existing production bottleneck and improves the production efficiency of unmanned automatic grinding by 80%; The existing manual grease coating method was changed to realize automatic grease coating of bearings, which improved the production efficiency by 200%… …

  In 2021, he participated in the trial competition of "CNC machine tool assembly and adjustment" project in the seventh national vocational skills competition for employees in Beijing, and won the first place. In the subsequent national competition of the same project, he won the national first prize of the project, the national champion of the event, and won the title of national technical expert. In the competition, he finished the parts processing, and the accuracy error was controlled at 0.02 mm, which is equivalent to one tenth of a hair.

  "The stage is as big as the heart." Hu Xingsheng said, serve the country with skills and strive to become a higher-level skill leader.

  A leaky spoon: persistent tempering and concentration

  Being a good cook, Liu Yang persisted for 18 years.

  Liu Yang is hanging soup. (Photo courtesy of the interviewee)

  The reporter went to a restaurant in downtown Yuzhong, Chongqing, and the chef Liu Yang was busy preparing a pot of soup. "I have loved cooking since I was a child, and I have tried to cook a pot of soup. Customers think it is delicious and I like it. Time seems to be in the taste of soup. "

  "A bowl of good soup can warm the stomach of the world", and a colander is his favorite tool. Every day at first light, Liu Yang went to the kitchen, and after several hours of cooking, hundreds of kilograms of water and more than 20 kilograms of beef, with the stirring of the colander, the soup base was clear and bright, and the fragrance was fragrant.

  Without persistence, it is difficult to temper concentration. He once failed to make soup, so he had to sum up the rules, keep trying and even work all night.

  Deeply cultivated in soup, but not limited to soup. Liu Yang learns from others’ strengths, captures the trend of experiential consumption, develops a variety of new dishes, and vacuum cooking is the first in its business. He participated in the innovation and improvement of 186 Chongqing Sichuan dishes, which promoted the development of Chongqing food culture.

  This year, Liu Yang won the National May 1st Labor Medal. He said that diet bears the culture of China, and every dish should be cooked well, so that customers can feel the humanistic power behind the food and the spiritual temperament of the Chinese nation.

  A microscope: precision in the microscopic world

  A microscope and a 4-square-meter workbench. The world of precision parts created by Lin Yudeng ranges from the research and development of watch movements to China’s manned spaceflight project.

  Lin Yudeng makes debugging molds on the workbench. (Photo courtesy of the interviewee)

  Lin Yudeng, 49, is the deputy director and senior technician of the model center of Fujian Shangrun Precision Instrument Co., Ltd., and a national model worker in 2020. From an ordinary die fitter to a master of skills, every day is "dead" with precision.

  After graduating from technical school, the master in the workshop gave him a ring on the spot, which was exquisite and smooth, as if it were alive, and opened an unprecedented world for Lin Yudeng and his "artisan life".

  In the world of precision manufacturing, it’s a drop in the bucket. When completing the research and manufacture of CH31 chronograph and seconds movement mold, 108 different sizes and accuracy requirements reached plus or minus 5 microns, and 18 tests were carried out before and after. After three months, Yu Lin Deng and his team finally tackled the problem and broke the foreign monopoly in this field.

  More than 19,000 truss structural shafts on the "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)" giant telescope were created by the team of model worker innovation studio led by Lin Yudeng. "Everything is not the same, there is no shortcut, and it is constantly fine-tuned while groping." "Eye of the Sky" was completed, and he was very proud at that moment.

  For more than 20 years, Lin Yudeng led the team to design and manufacture more than 200 pairs of molds, more than 100 varieties and more than 10,000 mold design drawings … … "It’s great to do one thing well all your life." — — This teaching from the master is often quoted by Lin Yudeng. "As long as simple things are done to the extreme, no matter how small the work is, it can also create a vast world."

  A flashlight: illuminating the "craftsman’s soul"

  Holding a flashlight and full of pulp, you often sweat in a high temperature environment of 30 to 40 degrees Celsius.

  Gu Ancheng judged the pulp color by flashlight irradiation. (Photo courtesy of the interviewee)

  This is the normal work of Gu Ancheng, the winner of the National May 1st Labor Medal in 2022 and the squad leader of Class B production in Qidashan Concentrator of Liaoning Angang Mining Company, as a flotation worker.

  On average, in each class, Gu ‘an and Chengdu have to go to the sampling point more than a dozen times. Pick up the pulp, carefully check the pulp color with a flashlight, then twist it by hand, feel the particle size of the pulp, analyze the material grade, and finally make records. In 23 years, he has done this action more than 40 thousand times.

  Under the tempering of time, it is becoming more and more firm, and the "artisan soul" slowly precipitates in repeated fishing, observation and twisting.

  In 2015, the industrial test of flotation column approved by Angang Mining Company was in the initial stage in the first dressing operation area of Qidashan Concentrator, and the indicators failed to achieve the expected results. Gu Ancheng carefully observed and studied, and put forward measures such as improving equipment operation speed and optimizing ore feeding granularity, and the technical indicators were obviously improved.

  A small flashlight can accomplish a big dream. For more than 10 years, Gu Ancheng has been honored. For the future, Gu Ancheng has made a good plan. Do not forget your initiative mind, be honest and innovative, and let "ingenuity" pass on from generation to generation.

  A paintbrush: Draw a happy life of the struggler.

  A brush, simple outline, clay sculpture seems to be endowed with life, vivid. This is what Zhang Xueyi, a sculpture technician in Licheng County, Shanxi Province, has done for 20 years.

  When he was a child, he liked local traditional opera costumes and facial makeup in Licheng. When the opera was left out in the cold, Zhang Xueyi had the idea of making opera masks into clay colored sculptures, "let the opera masks be circulated in the form of handicrafts."

  At that time, there were six or seven colors of painted pigments on the market, while painting faces needed more than a dozen colors. Zhang Xueyi groped for making pigments, which took him more than two years. When I first started painting, I sat in front of the painting table for more than ten hours every day, and a writing brush often had to be replaced in less than a week. The most important part of drawing a figure is the eyes. He has developed the habit of "staring at others when he meets", and some people tease him if he shows people faces.

  Persistence will pay off. His clay sculptures with local folk characteristics, such as One Hundred Faces of Shangdang Opera and Li Houhu, have won many awards.

  Li Hou’s color carving skills were listed in the intangible cultural heritage list of Shanxi Province in 2017. As a non-genetic inheritor, he founded a non-legacy technology innovation studio, trained and taught apprentices and employees hand in hand, and started a business with the villagers. Clay colored sculptures are exported, and more people know the local traditional culture of Licheng.

  This year, Zhang Xueyi won the National May 1st Labor Medal. "Happiness is a struggle!" He said, "Life is like a paintbrush, and the wonderful is in our own hands." (Reporter Tai Sicong, Huang Xing, Wu Jianfeng, Bai Yongquan, Liu Yangtao)

Where is the future of characterization in China’s comedy films?

    Observing two recent comedy films "Mr. Red Carpet" and YOLO, both veteran comedy director Ning Hao and rookie comedy director Jia Ling focus on portraying a hero who impresses the audience in their new works. This is not only an important guarantee for the quality of the two comedy films, but also shows us their respective characterization dilemmas, which is a very meaningful phenomenon. Taking this as an opportunity, we can start thinking about the future development of China comedy films.

    Mr. Red Carpet: How does absurd comedy create characters who can empathize with the audience?

    Starting from Crazy Stone in 2006, Ning Hao-style comedy has gradually become the most representative domestic comedy type after Feng’s comedy. Its basic formula is simply mature type+comedy+nobody. By learning from and mixing various mature types, its plot structure, characterization and artistic innovation ability are relatively strong. With the participation of small people, this comedy can produce works that are extremely suitable for social and cultural needs. It is precisely because of these advantages that Ning Hao-style comedy has led to the emergence of many excellent comedy films, which has contributed to the development of domestic comedy films in recent years.

    However, The Crazy Alien and The Beneficiary in 2019 marked some creative difficulties in Ning Hao-style comedies. The dilemma of Crazy Alien lies in Ning Hao’s desire to push his comedy creation to a new height, but it has raised the audience’s viewing threshold, and some songs are high and low. This made him have to face the confusion and confusion of whether to want art or box office. "The Beneficiary" reveals that there are also problems in the formula of Ning Hao-style comedy. First, there are mistakes and excesses in the borrowing and mixing of mature types; The bigger problem lies in the characterization, in which the little hero loses the real sense of life and is in danger of becoming an empty symbol.

    In the new director’s work "Second-hand Masterpiece" supported by Ning Hao in 2023, a new attempt of Ning Hao-style comedy can be observed, that is, the creation focus is completely on the characterization, and the work has successfully portrayed the image of the writer’s father. The creative thinking of "Mr. Red Carpet" is very similar to that of "Second-hand Masterpiece", and it still focuses on the characterization, which should be Ning Hao’s conscious pursuit of a breakthrough in comedy creation. Moreover, the portrayal of the hero in Mr. Red Carpet is still successful artistically.

    The characters are rarely three-dimensional and complex. In order to challenge and prove himself, Liu Weichi, the hero, started an adventure and showed his complex personality in this adventure. The film grasps the rhythm of plot development well, with both patient and meticulous plot preparation and plot climax. The appearance of one small incident after another pushes the protagonist to the corner of fate step by step and has to face the truth of his personality.

    Audio-visual expression is also very delicate. At the beginning of the film, an attitude towards the protagonist is established through a distant shot, that is, a critical presentation is made with a detached attitude. Many key scenes also show Ning Hao’s excellent audio-visual control ability. But he didn’t show off his skills, but served the characterization completely. The thinking reflected by the characters is more broad and layered. Some of these thoughts are related to the film itself: how to make a film in the era of short video and strong capital? What is the standard of art film? But there are also many thoughts beyond movies, which are related to our times and universal human nature.

    Regrettably, however, the audience did not buy this comedy film, which was so focused and successful in characterization. Among them, the biggest problem is that Ning Hao himself has fallen into a state of both necessary and important creation, which leads to the positioning error of the film. If it is positioned as an art film or an author film, this work can actually be explored more avant-garde in art. Because absurd comedy "is an exaggerated and profound serious comedy with philosophical connotation", on the one hand, it is highly intelligent and difficult to create, which puts forward higher requirements for the creator’s ability. On the other hand, it also means the possibility of innovation, which can help creators to explore the truth of life and the depth of human nature. If the creator’s ability is superior, it is possible to produce excellent works and classics. However, as a result, absurd comedy has a high threshold for viewing, and it is often difficult to become a high-box office movie because of the complexity and depth of thinking.

    Ning Hao’s twist is that he intended to put the film on the Spring Festival file before, which was originally for the box office. However, if we want to achieve high box office, we must make some improvements on absurd comedy. The previous Ning Hao comedies all had some absurd comedies, and an important magic weapon was to shape the image of a little person who was extremely close to the times and made the audience feel good. This makes Ning Hao-style comedies not only have a strong link with social reality, thus reducing the abstraction and despair of absurd comedies, but also enables the characters to form empathy with the audience. The box office success of Ning Hao-style comedies such as "Crazy Stone" and "Happy Flowers" depends on this.

    Mr. Red Carpet, on the other hand, is unwilling to make such improvement, but insists on its completely absurd characteristics and superior elite perspective. Not only is the content very abstract, but it also points the critical edge at everyone. The image of the hero is not only the spokesman of high social status, but also the symbol of abstract spirit, which not only makes the audience feel alienated and disgusted, but also can’t form empathy with the hero. So even if this comedy created a successful character, the audience still didn’t buy it.

    YOLO: How do the characters in autobiographical comedies surpass themselves after empathizing with the audience?

    The uniqueness of Jia Ling’s films is that she has been filming herself all the time. She has integrated her life experience into comedy creation and become a unique autobiographical comedy. This film content with her life experience also gave birth to a unique hero image in her comedies: sincere Jia Ling. This makes it particularly easy for the protagonist of her comedy movie to form empathy with the audience, which has become a weapon for her to win high box office. But this autobiographical comedy creation idea is very limited to commercial comedy:

    The first is the subject matter limit. Judging from Jia Ling’s two works, the first one can be completely original, but the second one can only be adapted from the existing one, because the autobiographical content is limited after all. However, the story and character logic carried by the adapted works will not only create tension with Jia Ling’s autobiographical pursuit, but also expose Jia Ling’s lack of ability as a new director. Love of a Hundred Dollars shows a story of a heroine who has lost hope in life and seeks the meaning of life again from boxing training. This state of life of bereavement and despair is obviously not suitable for comedy. This also leads to YOLO’s need to find new spiritual characteristics for the hostess in the adaptation, and it must also belong to Jia Ling’s own characteristics, so the protagonist in "Hot" is shaped as a flattering personality with Jia Ling’s personality characteristics.

    However, this change of the hero’s spiritual temperament must be supported by reasonable plots and characterization, which exposes the problems of Hot. In order to show the kindness of the heroine, the film portrays all the people around her as villains, and the changes of many characters are too abrupt and illogical. In fact, they are just tools to push the woman to boxing, and their role is to make her fall into a rebellious situation with high-density conflicts. The accumulation of punchline in the film has nothing to do with the main plot, and it is funny for fun. In order to make the audience agree with the female host’s flattering personality, the film even directly uses "two apples", "depending on the mood" and "two people can still hug each other like that. I thought that if you want to get a hug, you have to be kind to people! " Wait for the dialogue scene to output opinions straightforwardly. But in fact, the motivation connection between the female host’s flattering personality and boxing is still unconvincing. All these show that the first two-thirds of the film still has a lot of room for improvement in film quality. The main attraction of the film comes from the final climax, but it also comes from the shock brought by Jia Ling’s physical and mental changes to the audience. Many viewers even think that the final weight loss tidbits of the film are more shocking than the film itself.

    The second is the limit of self-consumption. Jia Ling in Hi, Mom formed empathy with the audience by virtue of her sincere and painful emotional ties with her mother. In YOLO, Jia Ling used the real change of the flesh to express a kind of strength and form empathy with the audience. The real weight change of gaining 40 pounds first and then losing 100 pounds has become the key to shaping the image of the heroine, which also brings the most important drama in the film. To gain 40 pounds first is to change the lovely image of Jia Ling’s fat figure in the eyes of the audience, so as to make the audience feel strange about her. Losing another 100 pounds will not only make Jia Ling’s body bring great visual impact to the audience, but also make Jia Ling’s body become an important carrier of tenacity, tenacity, self-discipline and self-confidence after successfully losing weight. However, this kind of self-consumption is limited to Jia Ling, both as a director and an actress, and it is difficult to continue. This also means that there is still great uncertainty about how to create a high-quality character image in Jia Ling’s next film.

    Where is the future of characterization in China’s comedy films? China’s comedy film creation has been relatively weak in recent years, and the lack of attention to characterization is one of the great reasons. Both Ning Hao and Jia Ling put their creative focus back on characterization, which has brought good enlightenment to China comedy films to get rid of the current creative dilemma. If we look at the characterization of the two works comprehensively, we can find a way out for the future characterization of China’s comedy films. Jia Ling’s success inspires the creators that creating comic characters that can make the audience empathize must be the basis and bottom line of commercial comedy. Ning Hao’s efforts show that empathy alone is not enough, and we need to work hard on the three-dimensional complexity of characterization, the synergy of plot and audio-visual, and the depth of characters. If we can focus on creating high-quality characters that make the audience empathize, there may be great hope for China comedy films to get out of the current bottleneck.
