Can the end-to-end model solve the last mile problem of autonomous driving？

In smart car technology, high-level autonomous driving is a difficult problem that major manufacturers and most Internet giants are trying to overcome. Whoever can take the lead in promoting the landing of advanced autonomous driving technology will be able to take the lead in automobile sales. In the high-order autonomous driving technology, the end-to-end model is the most discussed by all parties.

Compared with the previous model, end-to-end seems to have become the only way for advanced autonomous driving. So what is the end-to-end model? What is the development trend of end-to-end model in China? These problems are worthy of people’s attention.

What is an end-to-end model?

Speaking of the end-to-end model, it is natural to be inseparable from the ChatGPT of this year’s fire. ChatGPT itself is an end-to-end model, that is, by inputting words, customers can get the answers they want.

Whether it’s PPT or video, ChatGPT and other big models may spit it out. In this process, the most critical is the AI model. It can gain insight into users’ needs and produce the content they need.

In the field of autonomous driving, the most famous end-to-end model is Tesla’s FSD V12. The input of this model is all kinds of image data obtained by the camera; The output end is the vehicle control instructions, including steering, acceleration and braking. In the middle, it is a big model that Tesla is proud of.

In the scene of end-to-end model, when the vehicle recognizes some traffic signs or encounters various situations, it will automatically judge according to the past learning situation, instead of looking for a solution to this problem in the code according to various preset preconditions like the traditional model.

What are the advantages of the end-to-end model?

In contrast, in the past, the traditional autopilot model was based on the working conditions set by engineers in advance. The choice of driving behaviors, including lane changing, parking and even overtaking, has been set in advance. This will bring two problems:

Autopilot models are becoming more and more complex. Since each module usually only performs one driving behavior, the automatic driving algorithm needs to include the driving behavior of human drivers as much as possible. Therefore, the code of traditional autonomous driving technology usually has hundreds of thousands of lines of code. This will bring higher and higher requirements for the computing power of smart driving chips. Tesla’s FSD V12 has only 2000 lines of code; While FSD V11 has an astonishing 300,000 lines of code.

Unable to solve the long tail condition. No matter how full the preliminary test and certification are, no autopilot algorithm can say that all the long tail conditions are included. Then once you meet a new long tail working condition, it is very likely that traffic accidents will occur and even life injury accidents will occur.

The best case is that the project operated by GM’s Cruise in California encountered various working conditions that had not been encountered in the previous experimental stage at the beginning of its launch, which led to casualties, forcing the California Highway Bureau to suspend the license of Cruise for a time.

Where is the end-to-end difficulty?

To achieve an end-to-end model, there are two main limiting factors: massive data and large computing power. Only with the blessing of these two factors can the end-to-end model land. In order to make the end-to-end model closer to human drivers, its large model often needs to contain hundreds of millions of parameters. Only with more parameters can the driving characteristics and habits of human drivers be better simulated, and the performance of the model will be better. In these two areas, Tesla has a clear first-Mover advantage.

Not long ago, Tesla just got the certification of domestic data security and privacy protection, and was allowed to enter the government department compound. The reason why Tesla didn’t get the relevant recognition before was that the cameras in each car were collecting all kinds of data in real time and uploading them to the server for training the FSD algorithm.

Looking around the world, Tesla’s newly sold models every year are constantly providing data for the FSD V12 algorithm for the latter to continue to optimize learning.

It is worth mentioning that Tesla’s car also has a "shadow mode". It will compare the deviation between the driving behavior of the owner and the driving behavior determined by the automatic driving system, upload the relevant data together, and also optimize the algorithm.

At the same time, in order to be able to calculate the massive data collected, Tesla also needs a supercomputer center. The core of supercomputing center is the large computing power chip. For this reason, Tesla not only bought a large number of NVIDIA H100 chips, but even developed Dojo chips. The unit price of the former is as high as $35,000, while the investment in research and development costs of the latter is hundreds of millions.

For any enterprise, this is not a small expense. Domestic car companies have basically not been able to develop their own large computing chips. NVIDIA H100 chip has already become a product on the export control list of the United States, and it is difficult for domestic car companies to obtain it.

So is it possible to achieve the end-to-end model with massive data and large computing power? The answer is also no.

From the above description, we can find that the end-to-end model is actually a "black box". If there is an error in the model operation, it is actually difficult for researchers to find out what part of the model is wrong and directly adjust the model.

Theoretically, only through more training, or increasing more parameters and trying to adjust some model parameters can we try to solve the problem. Therefore, whether the autopilot model based on end-to-end technology can finally meet the needs of autopilot technology at the safety level is still very uncertain.

Even so, compared with the traditional autopilot model, the advantages of the end-to-end model are very obvious. Especially when solving the long tail condition, the end-to-end model can give play to the incomparable advantages of the traditional autonomous driving technology model. At present, some new car companies, such as Huawei, Tucki, Weilai and Ideality, have started to introduce the end-to-end model in the domestic market.

Aside from Huawei, which has abundant capital, it is a big challenge for new car companies with limited capital accumulation to balance the input and output returns of end-to-end technology. Not to mention, it is not an easy task to buy large computing chips in China at present.

With the high probability of the end of the year, Tesla FSD V12 will enter the domestic market. What changes will take place in the domestic market structure of autonomous driving technology at that time, which deserves people’s attention.

From January 1st, import and export tariffs on some medicines, raw materials and other commodities were lowered-more ＂zero tariffs＂ came.

　　Since January 1 this year, tariffs have started a new round of adjustment, and "zero tariff" has become a high-frequency word-

　　Implement zero tariffs on some anticancer drugs, medicines and raw materials for rare diseases; The provisional import tax rate of lithium chloride, cobalt carbonate and seed sweet corn was reduced to zero; China and Nicaragua immediately implement zero tariffs on products with about 60% of their respective tax items …

　　Experts said that in recent years, the overall tariff level in China has been continuously reduced, and more and more commodities have entered the "zero tariff era", which is not only conducive to enhancing the linkage effect of the two resources in the domestic and international markets, enhancing people’s livelihood and welfare, benefiting the development of enterprises, maintaining the stability and smoothness of the domestic industrial chain supply chain, but also conducive to promoting high-level opening up and allowing the world to share more opportunities for China’s development.

　　Imported goods—

　　The provisional tax rates for some anticancer drugs and resource commodities are adjusted to zero.

　　According to the latest tariff adjustment plan for 2024 (hereinafter referred to as the "plan"), from January 1st, China implemented a provisional import tariff rate lower than the MFN tariff rate for 1010 commodities.

　　After combing this plan, the reporter found that the provisional import tax rate of some drugs and raw materials was directly adjusted to zero, such as anticancer drugs for treating liver malignant tumors, raw materials for rare diseases for treating idiopathic pulmonary hypertension, and ipratropium bromide solution for drug inhalation which can be widely used in the treatment of childhood asthma diseases in clinic.

　　"The implementation of zero tariffs on some anticancer drugs, drugs and raw materials for rare diseases will help reduce the cost of drugs, reduce the burden of drugs for patients, especially cancer patients, and have more drug choices to further protect people’s lives and health." Zhang Jianping, deputy director of the Academic Committee of the International Trade and Economic Cooperation Research Institute of the Ministry of Commerce, said that in fact, in recent years, medicine has been the key area of tax reduction, and the import tariffs on many anticancer drugs, rare diseases and related raw materials have been reduced to zero.

　　On May 1, 2018, China adjusted the import tariffs on some drugs and cancelled the import tariffs on 28 drugs, including many kinds of imported anticancer drugs. Relevant measures quickly took effect. In October of that year, 17 kinds of anticancer drugs were included in the medical insurance reimbursement catalogue, with an average decrease of 56.7% compared with the previous average retail price.

　　Since then, China has successively cancelled a number of import tariffs on drugs and raw materials: in 2019, the provisional import tax rate of anticancer drug raw materials such as oxaliplatin, carboplatin, nedaplatin and cisplatin was adjusted to zero; In 2020, zero tariffs will be imposed on drugs for treating asthma and raw materials for producing new diabetes drugs, such as Engelgin, Liggliptin and Vigliptin; In 2021, the second batch of raw materials for anticancer drugs and rare diseases will be subject to zero tariffs; In 2022, zero tariff will be imposed on radium chloride injection, a new anticancer drug.

　　It’s not just drugs that are listed as "zero tariffs". This plan also explicitly reduces the import tariffs on lithium chloride, cobalt carbonate, low arsenic fluorite, sweet corn, coriander, burdock seeds and other commodities, and the provisional import tax rate has reached zero. According to experts’ analysis, lithium chloride, cobalt carbonate and other commodities are key raw materials for the new energy automobile industry, and fluorite is an important mineral resource. The obvious reduction of import tariffs on these products will help enterprises to allocate resources on a global scale, reduce production costs and enhance the resilience of the industrial chain supply chain.

　　"This tariff reduction mentioned coriander, which is often said by everyone, which is a major positive for our company’s imports." Xu Minghui, deputy general manager of Shandong Golden Seed Agricultural Development Co., Ltd. said that the company imports about 300 tons of coriander seeds every year, which used to cost about one kilogram of 15 yuan. After reducing tariffs, the import cost alone can save more than 600,000 yuan a year, which will help enterprises achieve better development.

　　Free trade partner-

　　The number of products with mutually cancelled tariffs has gradually increased.

　　This tariff adjustment involves not only the provisional import tax rate, but also the agreed tax rate. Zero tariff is also one of the highlights.

　　On January 2nd, Hubei ushered in the first "Zero Tariff" certificate of China-Nicaragua Free Trade Agreement. On the same day, Wuchang Customs, which belongs to Wuhan Customs, issued a certificate of origin of China-Nicaragua FTA for Chibi Yayuan Trading Co., Ltd., and the textile fabric certificate exported by this enterprise to Nicaragua can enjoy a tariff reduction of about 18,000 yuan from the importing country.

　　Yu Yawen, head of Yayuan Company, said: "We are mainly engaged in textile fabric trade, and Nicaragua is one of the export destinations of the company. After learning that the tariff rate of textile fabrics exported to Nicaragua in 2024 can be reduced from the original 10% to zero, we handled the certificate of origin under the guidance of the customs and enjoyed this tariff dividend for the first time. "

　　On January 1st this year, the China-Nicaragua Free Trade Agreement came into effect. According to the agreement, the two sides will achieve high-level mutual opening in the fields of trade in goods, trade in services and investment market access. In terms of trade in goods, the two sides will eventually implement zero tariffs on products with their respective tax items exceeding 95%, of which products with immediate zero tariffs account for about 60% of their respective total tax items. This means that when Nicaraguan beef, shrimp, coffee, cocoa, jam and other products enter the China market, the tariff will gradually drop to zero; When Chinese-made cars, motorcycles, batteries, photovoltaic modules, clothing and textiles enter the Nigerian market, tariffs will also be gradually reduced and cancelled.

　　Ivan acosta, Minister of Finance and Public Credit of Nicaragua, said: "The free trade agreement signed with China is a great opportunity for Nicaragua. We believe that entering the huge market of China will enable us to develop rapidly."

　　In recent years, China’s free trade "circle of friends" has been expanding. Shortly after the signing of China-Nepal FTA, China and Serbia signed a FTA, which is the 22nd FTA signed by China, and Serbia became China’s 29th FTA partner.

　　According to the person in charge of the International Department of the Ministry of Commerce, the China-Serbia FTA focuses on making relevant arrangements for trade in goods, and the two sides will cancel tariffs on 90% of the tax items respectively, and more than 60% of the tax items will be cancelled immediately after the agreement comes into effect, and the final import volume ratio of zero-tariff tax items will reach about 95%. Serbia will include cars, photovoltaic modules, lithium batteries, communication equipment, mechanical equipment, refractories, some agricultural and aquatic products that China pays close attention to, and the tariffs on related products will be gradually reduced from the current 5%-20% to zero; China will include generators, motors, tires, beef, wine, nuts, etc., which are of great concern to Serbia, into zero tariffs, and the tariffs on related products will be gradually reduced from the current 5%-20% to zero.

　　The new signing has been accelerated, and there have been new changes in the implementation. This year, the Regional Comprehensive Economic Partnership Agreement (RCEP) entered its third year of implementation, and 15 RCEP member countries will further reduce tariffs on products such as light industry, automobiles, electronics and petrochemicals according to the commitments of the agreement, and further increase the products that are included in zero tariffs.

　　"Since the implementation of RCEP for two years, the tariff reduction bonus has been released quickly. We have used the preferential policy of origin (accumulation rule) to export to RCEP countries, saving customers more than 5 million yuan in import tariffs, effectively improving the competitiveness of our products in the international market." Han Jie, Minister of Import and Export Customs of Dongyue Group, said.

　　Fan Ruojun, vice president of Guangxi Academy of Social Sciences, said that in the RCEP agreement, tariff reduction is the key content. According to the agreement, the member countries will set tariffs in pairs, gradually reduce the tariffs on more than 90% products to zero in about 10 years, and implement unified rules of origin in the region, stipulating that the value of goods’ origin can be accumulated in member countries, which will continue to promote trade liberalization and facilitation among member countries.

　　Free Trade Zone Free Trade Port-

　　The list of "zero tariffs" continues to expand.

　　Further promote the implementation of more "zero tariff" policies, and the free trade pilot zone and free trade port are at the forefront.

　　On December 29th, 2023, the Ministry of Finance, the Ministry of Commerce and other five departments issued an announcement to pilot relevant import tax policies and measures in the conditional free trade pilot zone and free trade port, which clearly stated that in the special customs supervision area where Hainan Free Trade Port implements the "first-line" liberalization and "second-line" control of import and export management system, goods temporarily allowed by enterprises to enter the pilot area for repair from abroad from the date of implementation of this announcement will be exempted from customs duties, import value-added tax and consumption tax.

　　The relevant person in charge of the Ministry of Commerce said that this measure has changed the "first-line" import duty-free and re-export duty-free of goods currently entering the special customs supervision area of Hainan Free Trade Port into direct duty-free, breaking through the current bonded policy; At the same time, it will be beneficial to the development of related maintenance industries to allow the goods that are no longer shipped out of the country to be sold domestically.

　　Hainan Free Trade Port has made new progress in "zero tariff" in recent years, including temporarily entering the country to repair goods. According to the latest data of Haikou Customs, since the implementation of the "zero tariff" policy for raw materials in Hainan Free Trade Port for three years, the customs has gone through the customs clearance procedures for the import of "zero tariff" raw materials, and the accumulated import value has exceeded 8.3 billion yuan, and the tax reduction has exceeded 1.1 billion yuan, effectively reducing the production and operation costs of enterprises.

　　On December 1, 2020, the "zero tariff" policy for raw materials of Hainan Free Trade Port was implemented. This policy makes it clear that before the whole island is closed, enterprises registered in Hainan Free Trade Port and with independent legal person status are exempted from import duties, import value-added tax and consumption tax when importing raw and auxiliary materials used for production and self-use, production and processing activities in the mode of "two ends out" or service trade in the mode of "two ends out". Enterprises do not need to submit a guarantee, but only need to pay the import duties, import value-added tax and consumption tax of the corresponding raw materials in domestic sales, so as to meet the business needs of Hainan Free Trade Port enterprises and alleviate the financial pressure.

　　Xu Lingling, chief of the Inspection and Evaluation Management Section of Haikou Customs Customs, introduced that the "zero tariff" policy for raw and auxiliary materials implemented positive list management, with the first batch of 169 listed commodities. By the end of 2021, after adjusting and adding 187 new commodities such as fresh durian, vinyl chloride and aero-engine parts, the number of listed commodities reached 356, including agricultural products such as coconut, resource products such as coal, chemicals such as vinyl chloride and parts for aircraft and ship maintenance.

　　After the "zero tariff" policy for raw materials, Hainan Free Trade Port successively implemented the "zero tariff" policy for vehicles and yachts and the "zero tariff" policy for self-use production equipment. On January 5th this year, Hainan released the Measures for the Administration of Zero Tariff Imported Vehicles and Yachts in Hainan Free Trade Port (Trial), and put forward 50 specific measures.

　　The relevant person in charge of the Hainan Provincial Department of Transportation said that the Ministry of Finance, the General Administration of Customs and the State Administration of Taxation recently issued a notice to adjust the "zero tariff" policy for vehicles and yachts in Hainan Free Trade Port, and added 22 items to the "zero tariff" import list. In the face of new situations and changes, the document issued this time will further enhance the adaptability of the "zero tariff" import vehicle and yacht policy.

How to solve these ＂hard injuries＂ of double clutch’s frustration and abnormal sound？

　　[Gearbox Technology] With the increasing publicity of major car companies in recent years, dual gearboxes are rapidly being accepted by ordinary consumers. The rapid and large-scale popularization has also fully exposed its shortcomings, especially the low-speed frustration, abnormal noise and poor stability of some gearboxes. So, the problem can’t be avoided?

Home of the car

　　Even if you are not the owner, it seems that you can easily tell the shortcomings mentioned above when you mention the dual-clutch gearbox, especially the dry dual-clutch gearbox. After everyone has experienced its extremely fast shift speed advantage, it is not difficult that it also has obvious shortcomings. To get the answers to these questions, we must first talk about the basics.

Home of the car

Home of the car

■ What is the gearbox thinking?

　　For me, the gearbox can be said to be the best partner. The characteristics of low speed, low speed and high torque are revived by the gearbox, which can make the engine release high torque in the low speed range and low torque in the high speed range, so as to meet the different needs of vehicle climbing, traction or fuel economy. All this is the credit of gearbox gear selection, so why does it shift gears?

Home of the car

Home of the car

Home of the car

　　When the vehicle is running, the gearbox computer will judge the state of the vehicle through the data transmitted by various sensors, and then it will operate. This process is actually quite similar to our human thinking about life in a daze. Put yourself in the position of thinking about the problems and personal status, and then give solutions, and then the process of practice is exactly the same as that of human beings. This is just a series of actions on the gearbox, which are completed in milliseconds.

■ Can the problems of frustration and abnormal sound be avoided?

　　The development engineer is the person who has the most say in all kinds of situations of dual-clutch gearbox and the methods and means to solve the defects. As it happens, the editorial department just bought a new 7-speed dry-type one, so we consulted its engineer in charge of the development of dual-clutch gearbox on related issues.

Home of the car

■ Not only software, but also hardware optimization can reduce frustration.

　　From the problems we have collected, it seems that some dry dual-clutch gearboxes have been criticized by many people for shifting at low speed, so where does this feeling come from? Can it be effectively changed only by adjusting the software control strategy?

Home of the car

　　In fact, there is a similar semi-linkage state in the power transmission process of dual-clutch gearbox, in order to reduce the wear of clutch plates. Therefore, the engineer will combine the clutch pressure plate with the friction plate as soon as possible. At this time, if the difference between the output speed of the engine and the output speed of the transmission is relatively large, there will also be setbacks.

Home of the car

　　The previous 7-speed dry dual-clutch gearbox with code DQ200 used mechanical control arm and sleeve to squeeze diaphragm deformation. From the structural point of view, its transmission efficiency is higher. After being optimized for hydraulic system, it can better filter vibration, thus further reducing the occurrence of frustration.

Home of the car

　　In addition, when it comes to low-speed gear shifting, some friends may feel that the performance of the gearbox is slightly different in the same speed range after the "cold car" state and the "hot car". This phenomenon actually does not only appear in the dual-clutch gearbox, but also exists in AT, etc.

Home of the car

　　In addition to the optimization of these gearboxes mentioned above, the ride comfort of vehicles is actually related to the engine. Its torque response speed is also one of the factors that influence driving experience. At the same time, the powertrain mounting design also affects the driver’s perceived ride comfort to some extent. Therefore, it can be said that the optimization of powertrain ride comfort is a far more complicated project than imagined.

■ Where does the abnormal sound come from?

　　The sound generated during the operation of the gearbox, or those unpleasant abnormal noises, will drive the user crazy more than frustration, so where is the source of the abnormal noise? How to optimize it?

Home of the car

Home of the car

■ Poor stability of dry dual clutch?

　　When it comes to dry dual-clutch gearbox, poor stability or prone to thermal protection is also a problem that people give more feedback. Compared with the natural "weakness" of gearbox structure, how do engineers solve this part of the problem in the development process?

Home of the car

Home of the car

　　In the testing process, the development team conducted a longer related test for congested road conditions, and simulated the extreme conditions that car owners would encounter in their daily driving on roads with severe congestion and long creep. Finally, through the improvement of clutch plate material and control strategy, the gearbox assembly reaches the design goal of 320 thousand km maintenance-free

Home of the car

Full text summary:

　　At present, in the domestic market, consumers often regard whether to use the dual-clutch gearbox as the standard to judge the technical maturity of a car. However, compared with the wet dual-clutch, the dry dual-clutch gearbox is more prone to overheating in the face of urban congestion and creeping road conditions because its clutch assembly has no oil to dissipate heat. The structural differences make it at a disadvantage in terms of stability. In addition, in the process of its work, the sound generated by the fork and clutch plate also affects the use experience to a certain extent. From the engineer’s point of view, the problem can be solved to some extent by software control strategy. In addition, some problems can be solved at the hardware level by using hydraulic control system and replacing clutch plate materials. (Text/Figure car home Tang Dynasty)

Faster Update and Greener Perception of Logistics Vitality from double 11

　　□ Reporter Liang Qian Wang Lu He Xinrong

　　With the opening of the curtain of "double 11" this year, the e-commerce platform ushered in a shopping spree, and the logistics express industry also ushered in a "big exam". According to the monitoring data of the State Post Bureau, from November 1 to November 4, the total collection of the whole network was 2.027 billion pieces, up 16.1% year-on-year and 31.0% quarter-on-quarter, reaching a new record high.

　　The distribution aging competition is more intense, the proportion of warehouse distribution integration is higher, and the green intelligent technology is more widely used. These not only reflect the vitality of the industry, but also reflect the resilience of China’s consumer market, which is a vivid portrayal of economic recovery.

　　On November 1 ST, Miss Gu, who lives in Hefei, Anhui Province, started to pay the first wave of final payment in Dapromotion less than an hour, and the express delivery was delivered to her. Express delivery speed is beyond her imagination. Behind this is the terminal outlet "Cangmeng" service launched by the courier company. After the customer pays the pre-sale deposit, the express mail sinks to the conditional outlet in advance, and the customer can deliver it immediately after paying the final payment.

　　According to relevant persons of Hefei Postal Administration, in order to cope with this year’s peak season, Hefei Postal Administration has invested about 20,000 square meters in new postal express delivery enterprises, equipped Yunda with 7 sets of automatic sorting lines, and put 113 unmanned express delivery vehicles into operation in Hefei. Shentong improved its service organization mode and launched the terminal network "Cangmeng" service for the first time this year. Yuantong continued to upgrade the equipment of the whole network transshipment center. Through the use of new technologies and equipment such as unmanned package pulling and unmanned parts supply, the efficiency of automation equipment in the whole network increased by over 10% year-on-year.

　　Different from the frequent "explosion" and "delayed delivery" in the past, more and more people feel the "speed" of logistics in double 11 in 2023. Under the all-round preparation of various express delivery companies, "order in the morning, delivery in the afternoon" and "order today, delivery tomorrow" are not uncommon.

　　Zhou Zhicheng, director of the Research Office of China Federation of Logistics and Purchasing, said in an interview with the Economic Information Daily that this year’s "double 11" express delivery industry has five characteristics: early, high, fast, new and green. As early as October 30th, the major platforms launched the first wave of promotion, and express delivery ushered in the first wave of peak, earlier than in previous years. High, the peak of the first wave of express delivery business is higher than that of previous years, indicating that the consumption power is relatively strong. Fast, through big data analysis, major platforms and express delivery companies have vigorously arranged pre-warehouses and deployed goods in advance, greatly shortening the service performance time and improving the customer consumption experience. New, all major companies are on the "black technology" of express delivery, which reduces the dependence of personnel during peak hours through intelligent distribution of equipment. Green, platform and express delivery companies generally use recycled packaging, green new energy vehicles, high-speed rail express, etc., which greatly reduces the carbon emissions of express delivery and realizes environmentally friendly development.

　　"This year ‘ Double 11’ Since its launch in late October, traffic has risen rapidly. " Hu Han, director of the Logistics Statistics Division of China Logistics Information Center, said that from the Baidu search index and WeChat index, the popularity of "double 11" has been more than 200% before the launch, but through the major logistics express delivery enterprises, demand forecasting and capacity planning have been generally increased to enhance the pressure resistance of logistics networks at peak and rush hour. At present, the backbone network is running smoothly, human resources are adequately equipped, and the terminal distribution capacity is strongly guaranteed.

　　In addition to the continuous improvement of the warehousing capacity of express delivery companies, the continuous optimization of transportation routes is also the key to speed up express delivery. On November 1st, the 20-day "double 11" online shopping peak railway express service was officially launched. Under the unified deployment of China National Railway Group Co., Ltd., China Railway Express Company gives full play to the advantages of high-speed rail network operation, safety and speed, actively adapts to market demand, and optimizes the allocation of transportation resources. More than 1,350 high-speed rail passenger EMUs are arranged to use the spare space of carriages and high-speed rail express cabinets to store express mail every day, more than 50 EMUs with reserved carriages for express mail, and 40 high-speed rail confirmed trains that leave in the early morning and have no passengers and can carry express mail.

　　Not only is urban logistics distribution speeding up, but with the sinking of major logistics express companies, more and more agricultural products are delivered to consumers’ tables "fresh".

　　“‘ Double 11’ Welfare delivery, impulse special beef jerky, without any additives, gold is 80% dry, shoot today and send it tomorrow. " On November 9th, Ebony Bi Lige was trying his best to introduce the home-made grilled beef jerky. He has been broadcasting live for 10 days, and his daily sales can basically reach three times of usual. Ebony Bi Lige said that on the one hand, he thanked e-commerce for letting their products be seen, and on the other hand, express delivery allowed their products to go further.

　　Express delivery into the village is an important channel for the smooth flow of industrial products to the countryside and agricultural products to the city. Like beef jerky in Ebony Bi Lige, in recent years, with the acceleration of two-way flow of rural express logistics, more agricultural products are sold all over the country through express delivery. At present, China has built 990 county-level public delivery centers and 278,000 village-level express service stations, and the coverage rate of express service in established villages has reached 95%. Smooth rural logistics has promoted the continuous growth of a large number of leading industries with regional characteristics, driven the continuous formation of a large number of influential local brands, and injected new impetus and vitality into agricultural and rural modernization.

　　It is worth mentioning that not only domestic logistics, but also the speed of cross-border logistics has been greatly improved. It is understood that after Cainiao and AliExpress upgraded Saudi Arabia’s "worry-free container service" in July this year, the combination of "X Rida" and "full package" was well received by local consumers, and both merchant orders and user experience were greatly improved. At present, the service has also been fully implemented in key Middle East countries such as the United Arab Emirates, Oman, Qatar and Bahrain. It is understood that this logistics upgrade can speed up the cross-border logistics of the four countries from 30 days to 12-14 working days, helping businesses to enhance the consumer experience. In addition, the logistics in the core area of North America is speeding up again. Cainiao International Express increased the local distribution resources reserve in the United States in the early stage of "double 11", which can shorten the local distribution time in major urban areas such as Los Angeles and new york to about two days.

　　“‘ Double 11’ Behind the express delivery fever, it conveys the signal that the market is warming up, reflecting the strong consumer demand. " Zhou Zhicheng said that since the beginning of this year, the policy of promoting consumption has been continuously strengthened and achieved remarkable results. In the second half of the year, it entered the traditional consumption peak season, and the promotion efforts of major e-commerce platforms increased, and there were many activities such as early drainage and price discount, which led to the accelerated release of demand and led to the improvement of express delivery business data. At the same time, cross-border e-commerce has maintained an accelerated growth rate, which has led to the vigorous development of international express delivery and logistics. Domestic express logistics enterprises have accelerated their "going out" and localized operations have become a trend.

Jackie Chan VS Wu Jing, the most noteworthy kung fu movie in ＂Spirit of Dragon Horse＂!


1905 movie network feature　A movie starring and starring in a special role, focusing on a generation of Dragon and Tiger martial artists. Since the release of the first batch of materials, the popularity has continued to rise, making it the most noteworthy kung fu movie in 2023. The kung fu superstar has come out again, and the sincerity of his debut for 60 years remains the same. Is the new team and new theme still a familiar taste?


"It’s time to start work. I was on crutches at that time, so I’ll go right away, close it here, close it there, nine stitches!"


"When I first saw the trailer, I didn’t feel like it was a Jackie Chan movie," said Ye Hang, an associate professor at the Beijing Film Academy and a veteran kung fu film enthusiast and researcher. "In the past, the trailer of Jackie Chan movies could not wait to cut all the essence of the action scenes, because this is the biggest selling point, but this time it is just a conversation between Jackie Chan and,. If you look closely, you will find that there is still a familiar taste of Jackie Chan in it."


Comedy effect

In the trailer, you can still see the shadow of the past kung fu comedies. At first, Jackie Chan sat upright, as if he was interviewing his prospective son-in-law.


"Why are you so nervous?"

"Not nervous."


But as soon as his daughter came in, all of a sudden, Jackie Chan became very nervous, restrained, and even a little cowardly, which is a common technique in comic effect.


Fight effect

With a comic effect, it is natural to have kung fu martial arts. In the film, Jackie Chan asks Guo Qilin’s character if he can fight and if he can protect his daughter.



In Jackie Chan’s early kung fu comedies, the purpose of his action scenes was to punish evil and promote good, but in this line in "Dragon Horse Spirit", he has changed, and the purpose is to protect his family. In that sense, it is still a Jackie Chan movie, but there are indeed many differences.



"The Spirit of Dragon Horse" is a work on the 60th anniversary of Jackie Chan’s debut. From the time Mr. Chan first appeared in a movie at the age of 8 to the age of 24, he started the era of kung fu comedy. Now he returns to the public eye with "The Spirit of Dragon Horse", playing the father of a "daughter slave". Jackie Chan has been active for 60 years on the big screen, sometimes laughing and sometimes desperately. This is a very difficult thing, and he has been able to stand for so many years. It is not by one trick that he eats the sky, but by advancing with the times and making positive changes.



When Jackie Chan was filming in 2004, he had already begun to try to change, not to play the hero who could never be beaten to death, but to play the ordinary person with blood, flesh and tears, and even kneel in some films. From the previous "fist" to the current "emotion", Jackie Chan has increasingly tried to play the father in the past decade, and the Jackie Chan-style father image is often very Chinese, with traditional Chinese virtues, external rigidity and internal softness, and special attention to rules.



Ye Hang put forward his own speculation about "Dragon Horse Spirit" based on the analysis: "Maybe the relationship between father and daughter will take the characteristics of’outer battle and inner love ‘, because there are many differences in thinking logic and way of doing things between the two generations. For example, in the choice of a mate, Jackie Chan’s father shows a kind of distrust, but the daughter likes it and even takes the initiative; for example, Jackie Chan’s character is in the business of dragon and tiger martial arts, and it is completely possible that the daughter, as a young man, does not agree or understand it. No matter how many conflicts there are outside the film, in the end, it will still fall to this point where the father and daughter are deeply in love, to form an emotional sublimation."



Last year, there was a documentary called, interviewed,, and other big names, which attracted widespread attention. The spirit of the Dragon Tiger martial artist is the spirit of striving for perfection and the ultimate, which is in the same vein as the spirit under the Lion Rock in Hong Kong society as a whole. In the 1980s in Hong Kong, the director made a film with many plots and details to show how difficult it is to be a Dragon Tiger martial artist. Jackie Chan is the most typical life-fighting action star. In it, he leaps deep from the bell tower; in the series, he hangs an umbrella on the roof of a Hong Kong bus. His film history can even be called a person’s injury history.



Wu Jing’s willingness to appear in "Dragon Horse Spirit" is based on his admiration for Jackie Chan’s eldest brother, which well reflects the cross-generational inheritance, and on the other hand, because they have the same growth experience as Dragon Tiger Martial Artists. The spirit of Dragon Tiger Martial Artists has a certain time distance from now. How to re-inspire vitality in the new era depends on whether the film creators can combine this spirit with the current story, plot and characters.



In addition to "Ryoma Spirit", other kung fu movie stars are also in full swing to shoot their own works, such as self-directed and self-starred, and have also released the first trailer, which is expected to be released next year.


"Everyone thinks that Wang Baoqiang rarely comes out this year. In fact, I have been doing this for six years."


Looking at it as a whole, the 2023 kung fu films have new characteristics and new atmosphere that are different from 2022. There are more innovations in the choice of themes and the integration of genres. For example, "In the Octagonal Cage" combines kung fu action elements with sports sports themes. Action movies, as a type of hard bridge and hard horse, also need creators to pay attention to plays. The selling point of martial arts as a genre itself is very important, but literary opera cannot be ignored either. It needs to be able to tell a good Chinese story through the film to make this film more contemporary. The current action genre films are constantly developing, and I believe that the majority of audiences are also looking forward to more innovations and breakthroughs in Chinese kung fu movies.

Director Luo Zhiliang said that in this scene, Nicholas Tse did not use a double, and took the initiative to run past the explosion point without any protective equipment, and the staff were worried for him during filming. In addition to this most dangerous scene, he can often be seen playing the sharpshooter in the film, accurately hitting the enemy’s eyebrows from 50 meters away, and he is always the fastest person when the two draw guns at the same time.

＂Meng＂ comes to ＂Meng＂! Follow the reporter to visit the ＂animal diplomat＂ in the zoo

"Source of this article: Guangzhou Daily"
In the history of Guangzhou’s foreign exchanges, apart from the exchange of visits between the government and citizens, these naive "animal diplomats" such as giant pandas, flamingos, mandrills, hippos and baboons are also worth mentioning. In fact, many citizens may have met them in the zoo!
How are these lovely "animal diplomats" doing now? Have they all had children? On the afternoon of November 22nd, Guangzhou Daily reporter came to Guangzhou Zoo to follow the steps of animal keepers and learn about their recent situation. These naive animals can be described as "bursting with popularity" in the park, attracting many citizens and tourists to stop and watch.
The hippopotamus Handa in Fukuoka, Japan:
Eating carrots and apples every day has given birth to 15 baby hippos.
Although it was Monday, when I came to the hippo living area of Guangzhou Zoo, the reporter found that many tourists were watching and taking pictures outside the guardrail, and many parents were explaining to their children.
"Handy, clear!" Liu Zufang, the breeder, approached the hippo’s hut and clapped his hands. Hearing the sound, two huge hippos suddenly walked into the small lake and swam towards the shore, waiting for feeding with their mouths open "meekly". Master Liu came to the lake with a plastic bucket filled with a dozen carrots and several apples, and successfully started the daily feeding process.
▲ Yida
Fukuoka, Japan is the first sister city in Guangzhou. The two cities have active exchanges and frequent exchanges in the field of animals. In 1980, Guangzhou borrowed giant pandas to Fukuoka, which caused a sensation in Fukuoka and even Japan. Since then, the two sides have also exchanged animals such as red-crowned cranes and flamingos.
In 2003, on the occasion of the 25th anniversary of the Sino-Japanese Treaty of Peace and Friendship and the 25th anniversary of the establishment of the two cities, Yamasaki Hirotaro, then mayor of Fukuoka, Japan, sent a special letter saying that he would give a hippo to Guangzhou, hoping to express the sincere greetings of Fukuoka citizens to Guangzhou citizens through animal donation.
On October 1st of the same year, Handa (English name: kanta), a male hippopotamus from Fukuoka Zoo, Japan, bearing the friendship between Guangzhou and Fukuoka, settled in Guangzhou Zoo. This lovely hippopotamus was born in Japan on December 26th, 2000. After he came to Guangzhou Zoo, he quickly tied the knot with the female hippopotamus born in this park. Handa is 21 years old this year and has become the father of 15 hippo babies.
"Handa is currently in good physical condition, weighing 1.5 tons, and eating about 2 pounds of carrots and 1 pound of apples every day." Liu Zufang has worked in Guangzhou Zoo for more than 40 years, and he is familiar with the living habits of various animals. In 2017, he began to take over the feeding work of Handa. At first, Master Liu was a little afraid of hippos. After getting familiar with them, he felt that they became cute. "Now I feel that these animals are like their own children."
"I didn’t know this hippo was sent by Fukuoka before. These animals are precious gifts, and we should take good care of them. " After hearing the explanation from the breeder at the scene, Miss Wu told reporters.
● Asian elephants in Vietnam:
Four hybrid elephants have been bred and their offspring can understand Cantonese.
When I came to the Asian Elephant Garden, I only heard the breeder Wu Qiyuan shouting "Baolong" and "Yuelong" in Cantonese. To everyone’s surprise, not long after, an elephant nearly 3 meters high came out of the rest house. This elephant, weighing nearly 5 tons, is called "Yuelong". It turned out to be a "hybrid elephant" and the largest Asian elephant in the park now.
Elon, a female Asian elephant, was a gift from Ho Chi Minh, a former Vietnamese national leader, to children in Guangzhou in 1960. She was 21 years old when she entered the park. After coming to Guangzhou Zoo, Elon not only acted as a messenger of friendship, but also took on the heavy responsibility of breeding offspring. He married the Asian elephant Babao who entered the park in Guangzhou Zoo in 1959, and successively bred four Asian elephants, including two sons, Baolong, 45, and Yuelong, 41, who have been exhibited in Guangzhou Zoo ever since. Elon and Babao died in 1983. They were made into specimens and placed in the Museum of Biology of Sun Yat-sen University.
"’Yuelong’ eats 380 kilograms of food every day, including grass, fruit, corn and so on. Usually, we also give each elephant a regular physical examination. " Wu Qiyuan studied veterinary medicine, and he admitted that he became a breeder because he liked elephants. "I hope to visit Vietnam one day and learn from their experience in caring for Asian elephants."
● Seychelles is a national ritual turtle;
"Cantonese-style recipes" can last as long as 200 years.
In October 2014, the rare giant Adabora elephant turtle from Seychelles, a beautiful island country in Africa, came to Guangzhou as a "diplomatic envoy" and officially checked into Guangzhou Zoo. Seychelles foreign ministers, ambassadors to China and garden representatives witnessed this grand event in Panlongyuan Park, and held a handover ceremony for the elephant turtle to settle in Guangzhou.
According to the staff of Guangzhou Zoo, the longevity of turtles is well known, and the elephant turtle is a well-deserved "longevity male among turtles". Adabora elephant turtle is the longest-lived tortoise in the world, with a life span of more than 200 years. When she entered Guangzhou Zoo, this Adabora elephant turtle was about 20 to 25 years old, and she was still a "young man" among the elephants. Elephant turtles eat a lot and can eat more than 20 kilograms of fresh leaves and other plants a day. After coming to Guangzhou, the garden also specially prepared "Cantonese-style recipes" for them, such as sweet potato vines, fruits and leaves.
"We all call it Dada, with a gentle personality and a weight of more than 230 kilograms. The Adabora elephant turtle comes from Seychelles, Africa, and its suitable living temperature is 28℃-30℃. It adapts well in Guangzhou most of the time. " Recently, the temperature in Guangzhou has dropped, and the breeder Chen Hong and his colleagues specially turned on the heating lamp for the elephant turtle in the house. See Chen Hong patted Dada’s back, and after stroking the turtle’s foot several times, it stood up obediently. "Dada likes brightly colored food. When we guide it to transition, we will use some green leafy vegetables or carrots to guide it to crawl."
"The elephant turtle has a long life, and we also expect it to live comfortably in Guangzhou Zoo." Chen Hong said.
