In order to strengthen the social supervision of the price, after-sales service and quality of online shopping products in double 11, China Consumers Association organized the price, quality and service survey experience of online shopping products in double 11 from October 2017 to January 2018. This survey and experience activity conducted a survey and experience on 16 online shopping platforms, involving 9 categories, including clothing, shoes and hats, mobile phone digital, food specialties, cosmetics and toiletries, home textiles, maternal and child products, luggage accessories, household appliances and other daily necessities. The investigation experience mainly involves price tracking records, seven-day unreasonable return operation, identification of "Haitao" goods, quality testing of non-"Haitao" goods and inspection of express delivery orders. The relevant survey experience results are as follows:

First, the price tracking record

In terms of price, from October 21st to November 21st, the experiencers selected 668 samples from 16 online shopping platforms with relatively large discounts and relatively large sales volume, and recorded the price changes of each product in detail through screen capture and other evidence collection methods. From the results of price tracking records, the commodity price behavior of 129 pre-sale samples is generally good, and only 4 pre-sale samples have higher prices than those after the pre-sale, or are suspected of price violations; Of the 539 non-pre-sale samples claiming to participate in the "double 11" promotion activities, 78.1% were able to buy promotional products at the price of "double 11" or lower on November 11th (regardless of the linkage activities). It is more prominent to increase the price first and then reduce the price, fabricate the "original price" and randomly mark the price (for detailed results, please refer to "China Consumers Association Information Network").

Second, the quality of goods

1. "Haitao" goods are suspected of counterfeiting more. In the identification of "Haitao" products, this survey experience actually purchased 93 samples of "Haitao" products, involving 37 brands. The experiencer contacts the brand trademark owner or the authorized person, and issues the commodity appraisal conclusion through consultation. Up to now, only the owners or authorized persons of 19 brands and trademarks have issued appraisal conclusions on 53 samples, of which 38 samples are genuine and 16 samples are suspected of counterfeiting.

Of the 53 samples, 5 are electrical samples, involving two brands such as Philips and Braun. According to the appraisal conclusion of the trademark owner or licensor, they are all authentic; Maternal and child products involve 10 samples from four brands including Kao, Garbo, Pampers and Wyeth, all of which are authentic.

Cosmetics involved 19 samples from 7 brands, including Shiseido, CPB, Lancome, Kiehl’s, Maybelline, Estee Lauder and Clinique. According to the appraisal conclusion of trademark owners or authorizers, 11 samples were genuine and 8 samples were suspected of counterfeiting. The products suspected of counterfeit goods are Shiseido Facial Cleanser sold by JD.COM platform "Meiya International Overseas Franchise Store", Estee Lauder Special Repair Muscle Penetration Essence sold by Jumei Premium Platform "Speed Duty Free Shop", and Shiseido Facial Cleanser sold by Honeybud Network Platform and Estee Lauder Multi-effect Wisdom Essence Cream sold by Honey Bud Select Merchants. Shiseido facial cleanser sold by jdf Beauty Shop on Pinduoduo platform, Estee Lauder ANR eye cream sold by Yadun Beauty Shop on this platform, Shiseido Anesuntan sunscreen sold by Kaleya Skin Care Family Store on Taobao platform, and Estee Lauder ANR eye cream sold by Netease koala online shopping platform "self-operated direct mail warehouse"; Footwear involves 10 samples from 4 brands, including Adidas, satchi, Aibu and Skye. According to the appraisal conclusion of trademark owners or authorized persons, 7 samples are genuine and 3 samples are suspected of counterfeiting. The goods suspected of counterfeit goods are Adidas clover Smith shoes sold by the Adidas /Adidas brand resident on Beibei. com, Adidas shell shoes sold by Gome online platform "Haikun Sports Franchise Store" and Adidas coconut shoes sold by Pinduoduo platform "Miss Cai’s Shoes" store; The luggage category involves 9 samples from 2 brands including coach and Michael Kors.According to the appraisal conclusion of the trademark owner or authorized person, 4 are genuine products and 5 are suspected counterfeit products. The goods suspected of counterfeiting are coach shopping bags sold by Dangdang platform "Luxury Taobao Global Shopping Franchise Store", coach Boston handbag sold by Gome online platform "Auchan Luxury Luggage Franchise Store", MichaelKors tortoise shell bag sold by JD.COM platform "Baiwang Overseas Franchise Store", coach shell bag sold by Pinduoduo platform "ishop Luxury No.1" and Taobao platform "Miss Yue Yue USA Purchasing".

In addition, the experiencers also contacted 18 other brands through various means, such as commodity information, website information and enterprise registration contact information, among which: Karen Murrell, AcQ, Kirkland and L ‘Occitane have never been contacted; Avène Avè ne, Free People, ARMANI Armani, Beineng, Deyun DEVONDALE, Huggies/ Curious and other six brands did not reply after the letter was delivered; Two brands, such as Burberry and GEOX Nutrilite, can only identify the goods authorized by the official direct channel, and other channels cannot determine the authenticity of the goods; The agent of line friends Brown Bear brand replied that there was no obligation to assist in authenticity identification; The samples of five brands, such as Aitamei, Mead Johnson, Hershey, Nike and Abbott, failed to complete the identification work due to the large demand, long period or other reasons for the same batch of samples.

2. The quality problem of non-Haitao merchandise clothing is relatively prominent. The experiencers sent 101 non-Haitao samples to institutions with relevant inspection qualifications for testing, tested their quality, and checked the sample identification and description. Quality test, identification and explanation of inspection results (this test result is only responsible for the samples submitted for inspection) show that 19 samples out of 101 have quality problems.

(1) The detected values of fiber content of clothing samples of individual platform merchants are inconsistent with the express. Fiber content is an important symbol reflecting the quality of fabric, the key for consumers to buy clothing products, and also an important factor to determine the value of clothing. The detection of fiber content in clothing is inconsistent with the express statement, and the manufacturer does not label it according to the actual composition of the fabric, which will mislead consumers and damage their rights and interests. The Label of Textile Fiber Content (GB/T29862-2013) stipulates that when a certain fiber content on the fiber content label is less than or equal to 10%, the fiber content tolerance is 3%; When the fiber content is less than or equal to 3%, the actual content shall not be 0. When the fiber content of a filler on the label is ≤ 20%, the fiber content tolerance is 5%; When the fiber content of a filler is ≤ 5%, the actual content shall not be 0. The test results show that the nominal "Tiffany Runchi" brand wool coat sold by JD.COM platform "Tiffany Runchi Women’s Flagship Store" has 53.9% wool, 30.6% polyester fiber, 6.5% cotton, 3.4% viscose fiber, 2.9% nylon, 2.7% acrylic fiber, and 94.2% polyester fiber as the test lining. The fabric and lining of the nominally "Xiyan" brand children’s down jacket sold by the "Fruit Girl Children’s Wear" store on Taobao platform are 100% polyester fiber, but the fabric and lining marked by the commodity tag are 100% polyester.The washing label indicates that the fabric and lining are 100% nylon; The detection value of the nominal "Youmai" brand sweater fabric sold by Tmall platform "Youmai Clothing Flagship Store" is 68.7% viscose fiber and 31.3% polyester fiber, while the fabric marked by the commodity tag is 52% polyester, 28% cotton and 20% spandex.

(2) The color fastness of some platform merchants’ clothing sample fabrics does not meet the standard requirements. Dyeing fastness is mainly to assess the fastness of dye adhesion to fiber. The range values of dyeing fastness of first-class products, superior products and qualified products are clearly defined in the corresponding standards of products. Unqualified color fastness In the process of wearing or washing, the pigment falls off and is transferred to the skin, which will harm the human skin or contaminate other clothes, directly affecting the health and beauty of consumers. The test results show that the color fastness (staining) of the nominal "Hengyuanxiang" brand sweater sold by Dangdang platform "Brioso Brioso franchise store" is 2-3, while the standard of national general safety technical code for textile products (GB18401-2010) (hereinafter referred to as the standard) requires it to be ≥3; The color fastness to soaping (staining) of the nominal "Tiffany Runchi" brand woolen coat sold by JD.COM platform "Tiffany Runchi Women’s Flagship Store" is 2-3, and the standard requires it to be ≥3; The color fastness to water of the nominal "Sponge Bubble" brand windbreaker jacket fabric sold by Pinchuang Trade Store on Jumeiyou platform is 2-3, while the standard requires it to be ≥3-4, the color fastness to acid and perspiration (staining) is 2-3, while the standard requires it to be ≥3-4, and the color fastness to rubbing (wet rubbing) is 2-3. The nominal "Ou Li Mommy" sold by Jumeiyou platform "Ou Li Mommy Clothing" store.The color fastness to rubbing (wet rubbing) of brand trousers is tested as grade 1, while the standard requires it to be ≥2.

(3) The formaldehyde content of infant clothing samples from individual platform merchants exceeds the requirements of relevant standards. Formaldehyde is an irritating gas, which can enter the human body through diet, breathing or skin contact. Formaldehyde is a safety index of clothing, which will cause harm to human body if it exceeds the requirements of national standards. According to relevant reports, formaldehyde will irritate eyes, skin and mucous membranes, and the use of additives containing formaldehyde in the production of textiles will lead to excessive formaldehyde content, which will cause serious harm to health. According to the standard requirements of national general safety technical code for textile products (GB18401-2010), the formaldehyde release content of finished products is limited to infant clothing (two years old and below) ≤20 mg/kg, clothing that directly contacts the skin ≤75mg/kg, and clothing that does not directly contact the skin ≤300 mg/kg. The test results show that the formaldehyde content of the coat fabric and lining of the nominal "Sponge Bubble" brand windbreaker sold in the "Pinchuang Trade" store of Jumeiyou platform is 28mg/kg and 43mg/kg respectively, while the standard requires infant clothing (two years old and below) ≤ 20 mg/kg; The formaldehyde content of the nominal "Yu Zhaolin" brand leggings sold by Pinduoduo platform "Shuduo Clothing Franchise Store" was 109mg/kg, while the formaldehyde content of the clothes that directly contacted the skin was ≤75mg/kg according to the standard.

(4) The pilling and pilling indexes of some platform merchants’ clothing samples failed to meet the standard requirements. Pilling is not only one of the important factors that affect the feel, appearance and wearability of clothing, but also affects the service life of products. According to the requirements of related standards such as "Determination of pilling performance of textile fabrics" (GB/T4802.1-2008, GB/T4802.2-2008), the test results show that the test results of the nominal "Hengyuanxiang" brand sweater pilling item sold by Dangdang platform "Brioso Brioso franchise store" are 1-2, while the related standards require it to be ≥ The measured wear resistance of the nominal "Handu Yishe" brand jeans sold by Dangdang platform "Handu Yishe Flagship Store" is 14,000 times, while the relevant standards require ≥ 25,000 times; The test result of the nominal "Ou Li Mommy" brand trousers pilling project sold by Jumeiyou platform "Ou Li Mommy Clothing" store is Grade 2, while the relevant standards require it to be Grade 3 or higher; The test result of the pilling project of the nominal "Lalajia" brand sweater sold by Pinduoduo platform "Lalajia Women’s Flagship Store" is Grade 2, while the relevant standards require it to be ≥2-3; The test result of the pilling project of the nominal "Youmai" brand sweater sold by the Tmall platform "Youmai Clothing Flagship Store" is Grade 2, while the relevant standards require it to be Grade 3 or higher; The test result of the pilling project of the nominal "Youmai" brand sweater sold by the "Youmai Designer Women’s Wear" store on Taobao platform is Grade 1, while the relevant standards require it to be ≥2-3; Netease koala sea purchase platform "Dapu home furnishing franchise store"The test result of the pilling project of the nominal "Dapu" brand bedding sold is Grade 2, while the relevant standards require it to be Grade 3 or higher; The test result of the pilling project of the nominal "Trendiano" brand woolen coat operated by Amazon platform is Grade 1, while the relevant standards require it to be Grade ≥3-4. In addition, the peeling strength project of the adhesive lining does not meet the standard requirements.

(5) The down jacket samples of individual platform merchants have cracking indicators or the types of down jackets do not meet relevant standards. Slip, seam performance and so on are the sewing strength of clothing, which is used to check the degree of yarn slippage after the external force is applied to the seam of clothing during wearing or using, and is the main index to check the durability of woven clothing products. Clothing cracks will not only affect the beauty of clothing, but also seriously affect the service life of clothing. The test results show that the lining crack of the nominal "Xiyan" brand down jacket sold by the "Fruit Girl Children’s Wear" store on Taobao platform is 20px, while the standard of Down Clothing (GB/T14272-2011) requires it to be ≤10px.

In addition, the survey experience also found that the measured down types of individual down jackets did not match the claims. For example, the down feather category of the nominal "Playboy" brand down jacket sold by Gome’s "Famous Brand Clothing Franchise Store" is land bird feather, while its product claims to be 90% white duck down; The down feather category of the nominal "Xiyan" brand down jacket sold by the "Fruit Girl Children’s Wear" store on Taobao platform is land bird feather, while its products claim to be 80% white duck down.

(6) The shock and impact resistance of individual platform merchants’ luggage samples did not meet the standard requirements. Unqualified shock and impact will easily lead to the separation of luggage tie rods, straps, handles, side handles and other components from the bag body, and will also cause the fabric of the bag body to break and open. Impact resistance is an important performance to test the quality of luggage case. During the use of luggage case, it is inevitable to encounter the problem of falling. Unqualified impact resistance seriously affects the service life of luggage case. The test results show that the connector of the nominal "Woodpecker" brand handbag in the "Woodpecker Leather" store of Jumeiyou product platform is broken during the shock performance test; Luggage case, the nominal brand of "OSDY" sold by Dangdang platform "official flagship store of OSDY luggage", cracked during the drop test of the impact resistance project.

(7) There are problems with the acid value index or sodium content of food samples from individual platform merchants. Acid value is an index to measure the rancidity degree of oil. The higher the acid value, the worse the quality of oil. The smaller the acid value, the better and fresher the oil quality. The rancidity and deterioration of oil will reduce the nutritional value of food. The test results show that the acid value of the nominal "Western Region Meinong" brand roasted cashew nuts self-operated by our website is 3.7mg/g, which is not in line with the standards of Nuts and Seed Foods (GB 19300-2014) and Food Additives Usage Standards (GB2760-2014). In addition, the nominal "Gongtianxia" brand rose flower cake operated by Vipshop platform has a sodium detection value of 880mg/kg and a label value of 190 mg/kg; The sodium detection value of the nominal "Western Region Meinong" brand roasted cashew nuts operated by our online platform is 1170mg/kg, while the commodity label value is 750mg/kg, which fails to meet the requirement that the sodium is less than 120% of the label value in the National Food Safety Standard General Rules for Nutrition Labeling in prepackaged foods (GB 28050-2011).

(8) The residual amount of plasticizer in liquor samples of individual platform merchants exceeded the standard. Di-n-butyl phthalate (DBP) (plasticizer) exceeding the standard will seriously affect human health, and it will bring potential harm to human body after being absorbed by human body. The test results showed that the detection value of dibutyl phthalate (DBP) in the liquor sold by Pinduoduo platform "Fuyulong Liquor Franchise Store" was 0.699 mg/kg, which did not meet the requirements of the former Ministry of Health for the maximum residue of phthalate esters in food and food additives (0.3mg/kg).

Third, the after-sales service situation

1. No reason to return the goods within seven days is better. As an ordinary consumer, the experiencer returned 101 samples of goods that were not marked with "No reason to return for seven days". The survey results show that among 101 samples, 96 samples have completed the return operation, which shows that merchants on all platforms have done a relatively good job in complying with the seven-day unreasonable return rule; Only five samples failed to be returned, namely, the nominal backpack of a certain brand sold by Gome’s online platform Swiss Army Knife Gear Flagship Store, the noodle machine of a certain brand sold by the store of Jiuyang Xiaoxiang Tribe Electric City on Taobao platform, and the sports shoes of a certain brand sold by Tmall platform sneakerhead Overseas Flagship Store, etc., which were not marked as not supporting the return for seven days without reason, but refused to apply for return in the after-sales link. In addition, a brand of rice flour and a brand of milk powder self-operated by Beibei. com marked "seven-day worry-free return" on the product information page, but the experience personnel found that these two models did not support seven-day unreasonable return.

In addition, the experiencers checked whether the "Haitao" samples sold through the cross-border e-commerce platform support seven-day unreasonable return. The statistical results show that among the 100 "Haitao" samples in this survey experience, 62 samples clearly indicate on the display page or the purchase page that seven-day unreasonable return is not supported. Moreover, even if there is no reason to return goods for seven days, consumers often choose to return goods because of the high freight and taxes.

2. The protection of personal information by express delivery is generally weak. The experiencers made statistics on the privacy protection of 206 delivery orders of goods from 16 online shopping platforms. The express list of this experience involves Baishi Express, Jingdong Express, Pinjun Express, Shentong Express, Suning Logistics, SF Express, Postal Express, Yuantong Express, Yunda Express, ZTO Express and other major domestic express companies. The statistical results show that the above privacy protection measures are not found in the express sheets of SF Express for two packages, SF Express for two packages and Suning Logistics for three packages.

IV. Conclusions and recommendations

Through this survey and experience activity, it is reflected that some platform merchants can abide by relevant regulations in terms of price behavior, quality management and after-sales service, and all parties have performed relatively well. For example, Gome online platform self-operated "Midea" brand rice cookers, JD.COM platform "SWANSHINY Cosmetics Official Flagship Store" sold "Double Decade" brand pomelo extract cleanser, Jumeiyoupin platform self-operated "Appropriate Herbal Medicine" Rhodiola whitening skin care suit, Suning.cn platform self-operated "Patriot" brand mobile power supply, etc., the survey experience is relatively good. It is hoped that the relevant platform merchants will strictly meet the quality and service standards and further meet the higher requirements of consumers for improving the quality of consumption.

Judging from the results of this survey experience, in most cases, "double 11" is not the most favorable for non-pre-sale goods; It is difficult to realize "unreasonable return" of "Haitao" goods, and there are many cases of suspected counterfeiting; Among non-Haitao goods, the quality problem of clothing products is relatively prominent. At the same time, the survey experience also found that the privacy protection measures of most express delivery companies are still not enough, and consumers’ personal privacy is easily leaked during the delivery of goods. The survey results show that during the online shopping in double 11, some platforms and businesses have many weak links in the protection of consumers’ rights and interests, and some even seriously damage the legitimate rights and interests of consumers, which is not conducive to the construction of a safe and secure online consumption environment. Online shopping is an important channel for operators to close the distance with consumers, and it is also an important pusher to promote the improvement of consumption quality. In order to create a good online shopping environment and effectively protect the legitimate rights and interests of consumers, the China Consumers Association suggests that:

1. Platform merchants should be guided by quality consumption, consciously regulate price behavior, and ensure the quality of platform products. According to the survey experience, many platform merchants are still used to fighting price wars or perplexing and misleading consumers through complicated price expressions, but they don’t pay enough attention to the quality control of online shopping products, which leads to the counterfeit problem of some "Haitao" products during the centralized promotion of e-commerce, and the quality problems of clothing and luggage products of individual e-commerce platforms are frequent. I hope that all e-commerce platform merchants: First, strictly abide by the national laws and regulations on prices, advocate clear prices, make clear discounts and deductions, and put an end to price misleading and price fraud; The second is to improve the qualification review mechanism of platform merchants, strengthen the whole process quality control of platform commodities, guide and adapt to consumers’ demand for quality consumption, and attach importance to consumers’ feedback on quality and service; Third, take effective technical protection measures to strengthen the protection of consumers’ personal information in terms of data collection and use, order display, communication and express delivery.

2. The relevant government departments should strengthen the supervision and management of online shopping, adhere to collaborative governance, and severely punish e-commerce illegal and untrustworthy behaviors. In the past three years, China Consumers Association and some local consumer associations have continued to carry out online shopping product quality and service supervision activities, reflecting many problems in terms of price, quality and service of relevant platforms and businesses. Some businesses use the platform to single out speculative letters, sell fakes and cheat consumption, which has seriously damaged the online shopping environment. It is suggested that the relevant government departments: first, further improve the legal provisions of online shopping supervision, adopt a combination of random sampling and key supervision, increase the supervision and management of online shopping market, and urge platform merchants to be honest and trustworthy and operate according to law; The second is to establish and improve the co-management and co-governance mechanism of online shopping, provide support for the construction of social credit system with big data analysis methods, increase the comprehensive punishment for serious illegal and untrustworthy behaviors, and create a safe and secure online consumption environment.

3. Call on consumers to establish the concept of quality consumption, adhere to smart and rational consumption, and develop a good awareness of consumer rights protection. According to the experience of this survey, the price representation of some e-commerce products is complicated and difficult to understand. Even experienced people can’t calculate the actual sales price of some products, which leads many consumers to fall into the trap of business price, and the quality and service are uneven. Consumers are not discerning and it is difficult to get benefits. Appeal to consumers: First, participating in online shopping should be guided by meeting their own consumption needs, adhere to quality first, carefully compare and identify, pay attention to the sampling results of relevant government departments, the survey results published by consumer associations and related organizations, and especially be alert to the price trap of e-commerce, and don’t covet unreasonable low prices; Second, learn and master the necessary common sense of consumption and legal knowledge, and pay attention to keeping the shopping screenshots and valid vouchers in the online shopping process. Once online sales of fake goods, false propaganda, price fraud and services are found to damage consumers’ rights and interests, they should promptly complain to the platform, relevant government departments or local consumers’ associations.

1905 movie network news A few days ago, the film released the MV with the same title. The lyrics were adapted from Li Bai’s Tang poems, and Tayu Lo sang in love, which showed the lofty sentiments and ambitions contained in Li Bai’s poems to the fullest. It also made people very much look forward to how the film will tell the life friendship between Gao Shi and Li Bai and the magnificent life path of the Tang Dynasty stars in pursuit of ideals. The film will be released nationwide on July 8.

Fantastic coorperation

Tayu Lo’s Passion and the Millennium Resonance of Li Bai, the Poet Fairy.

The film Three Wan Li in Chang ‘an is based on the history of the Tang Dynasty, and tells the wonderful story of the Tang Dynasty stars led by Gao Shi and Li Bai chasing their ideals in the magnificent Tang Dynasty. The lyrics of the ending song of the same name were created by Tayu Lo adapting several Tang poems of Li Bai, and the lyrics appeared in Li Bai’s famous works, such as Coming into Wine, it is hard to go and down Zhongnan Mountain to the Kind Pillow and Bowl of Husi.

When Tayu Lo sang Li Bai’s poems "since heaven gave the talent, let it be employed!" and "sober men of olden days and sages are forgotten, and only the great drinkers are famous for all time", which have been circulated for thousands of years, with a charming voice, even if they were separated by thousands of years, the audience could still feel the heroic and uninhibited spirit of Li Bai, a poet, and people were very much looking forward to how Chang ‘an Three Wan Li would show the colorful chapters of Li Bai, the "Bai Yueguang in China’s heart".

Shock ancient and modern times

The stars of the Tang Dynasty shine brightly, and the current poems will be in Chang ‘an.

At the same time, the MV of the ending song of Chang ‘an Three Wan Li also shows the lifelong friendship between Gao Shi and Li Bai. Gao Shi’s ideal of "worldly people" is to "gallop on the battlefield" like his ancestors, while Li Bai, a "fallen immortal", wants to "rise with the wind" like Dapeng. In the film, two people with different ideals will write wonderful stories that have been talked about by the world until today with the stars of the Tang Dynasty under the background of the Tang Dynasty.

It is worth mentioning that the chanting of Tang poems in the MV is in line with the display of the grand scene of the Tang Dynasty, which makes the audience seem to return to the era when poets such as Li Bai, Gao Shi and Du Fu lived, and follow their footsteps to feel the charm of Tang poems and the romance that belongs to China people alone. As the old Gao Shi said at the end of the MV, "As long as the poems are there, Chang ‘an will be there."

　　Today (November 10th) morning, National Cultural Heritage Administration held a press conference on the progress of the major project "Archaeological China" in Beijing, and reported the latest achievements and progress in the archaeology of Yin Ruins and the study of Oracle Bone Inscriptions.

　　I. Archaeological Discovery and Research of Yin Ruins

　　Yin Ruins, located in Anyang City, Henan Province, are the ruins of the capital in the late Shang Dynasty. Since 1928, archaeologists in China have begun to carry out scientific archaeological excavations of Yin Ruins, which has opened the curtain of modern archaeology in China. Up to now, more than 90 years have passed, and important relics such as the palace area, residence area, tomb area, handicraft workshop area of Yin Ruins have been discovered one after another, as well as the neighboring Huanbei Mall, the capital of the middle Shang Dynasty, and a large number of precious cultural relics such as Oracle Bone Inscriptions, bronzes, pottery and jade wares have been unearthed. The distribution and structural layout of Yin Ruins were basically cleared up, and the chronological system of Yin Ruins culture was established, which provided a basis for exploring the archaeological culture of the early Shang Dynasty and even the Xia Dynasty. The research on the capital system, tomb system, sacrifice system, handicraft production system, architecture, water conservancy, spiritual belief and other aspects of the Shang Dynasty continued to deepen, demonstrating the history of the Shang Dynasty recorded in the literature and systematically showing the social and cultural features and the development achievements of the Shang Dynasty civilization. In 2006, Yin Ruins was listed in the World Heritage List, and its outstanding universal value was generally recognized by the international community, which provided a strong support for enhancing national self-confidence.

　　The archaeology of Yin Ruins has entered a new era and stage. Under the guidance of the concept of settlement archaeology, it has deepened the multidisciplinary and interdisciplinary cooperative research and made new breakthroughs. A large number of relics of copper casting, bone making, pottery making, living and living, and well-distributed cemeteries were found in the workshop area of Huanbei handicraft industry, which revealed the layout mode of "residence and burial in one" integrating production, life and funeral, and vividly displayed the production picture of handicraft industry in Shang Dynasty. Large ponds, waterways and related architectural relics have been newly discovered in the ancestral temple area of Xiaotun Palace, covering an area of more than 60,000 square meters. The ponds are connected with Huan River through waterways, which has changed the previous understanding of the overall pattern of the ancestral temple area of Yinxu Palace. Based on the exploration and excavation around the tomb area of Yin Ruins, it is confirmed that the eastern part and the western part of the tomb area are surrounded by a trench with a width of more than 10 meters, and the tomb and a large number of sacrificial pits are located in the trench. The discovery of the trench breaks through the understanding of the layout of the tomb area of Yin Ruins and is a major progress in the study of the cemetery system in Shang Dynasty. The road system inside the Yin Ruins has been continuously revealed. Two north-south roads leading directly to the palace area were found about 1km south of the ancestral temple area of the Yin Ruins, and a large road with a width of 15m was excavated on the north bank of Huanhe River. There were clear rutting marks on the roads, and residential areas, tombs, handicraft workshops and so on were densely distributed on both sides of the roads. The framework system revealed by the roads provided important clues for further exploring the urban layout and ethnic distribution of the Yin Ruins. Under the guidance of new ideas and methods, the archaeological research of Yin Ruins will gradually restore a more comprehensive, real and vivid Shang civilization.

　　Second, the new archaeological discoveries of settlements around Yin Ruins

　　Henan Province and Anyang City have implemented the policy of "archaeology first, then transferring" and actively strengthened the archaeological and cultural relics protection work in urban capital construction, and achieved many important achievements in the archaeological work of capital construction around Yin Ruins, greatly expanding the breadth and depth of archaeological research in Yin Ruins.

　　Xindian site, located about 10 kilometers north of Yinxu Palace, is a bronze casting site. Seven bronze casting workshops, more than 10 houses and nearly 100 tombs have been found in the late Shang Dynasty, and about 40,000 pieces of pottery models, pottery molds and a large number of tools for making models and casting copper have been unearthed. The unearthed bronzes bear the inscription "Ge", indicating that the site may be a bronze casting site managed by the "Ge" clan.

　　Taojiaying site is located about 7.2km north of Yinxu Palace. It is a moat settlement in the middle of Shang Dynasty. Pottery production area, residence area and tomb area were found in the site, and rich bronzes, jade articles and pottery were unearthed in 25 tombs, which further enriched the social research content of settlements around Huanbei Mall in the middle of Shang Dynasty.

　　Shaojiapeng site, located about 2.5km south of the palace area of Yin Ruins, is a settlement in the late Shang Dynasty. Three groups of multi-entry courtyards consisting of 18 houses and a graveyard consisting of a Chinese-shaped tomb, 23 small and medium-sized tombs and 4 chariots and horses pits were found in the site. Many bronzes with the inscription "Book" were unearthed in the tombs, indicating that Shaojiapeng site may be the "Book" of historians in the late Shang Dynasty.

　　Third, Oracle Bone Inscriptions’s discovery and research

　　Oracle Bone Inscriptions is the representative of the early mature Chinese character system, and it is also the demonstration of Yin Ruins as the capital of Shang Dynasty. Oracle Bone Inscriptions was unearthed in Xiaotun Village, Anyang, Henan Province in the late Qing Dynasty. Up to now, about 150,000 pieces have been discovered, and more than 35,000 pieces have been scientifically excavated. The number of words has exceeded 4,000, covering all aspects of politics and life in Shang Dynasty, and it is the direct historical data for rebuilding the history of Yin and Shang Dynasties. There are three important discoveries of Oracle bones in Yin Ruins, namely, the largest number of intact pit YH127 in Xiaotun, the Oracle bones in the south of Xiaotun with a clear date, and the Oracle bones in the east of Garden Village in Yin Ruins with unique historical value. Oracle bones in Yin Ruins directly confirmed the existence of Shang Dynasty in ancient historical records, and Xiaotun in Anyang was Wang Ting of Yin Shang Dynasty, which advanced the upper limit of China’s trust history by more than 1000 years, opened the archaeological and historical research course of Yin Ruins for more than 90 years, and promoted the innovation and development of China’s traditional philology.

　　More than 120 years’ research on Oracle Bone Inscriptions has yielded fruitful results in Oracle Bone Inscriptions’s data collation, chronology by stages, textual research, business history research, compilation and publication of reference books, and personnel training. Based on the profound academic accumulation of more than a hundred years, the study of Oracle bones in the new era pays more attention to the combination with archaeological theories and methods and multi-disciplines, and has made important achievements in promoting the study of ideological history, astronomical calendar and historical geography, and solved the problem of digital divination, which is of breakthrough significance and value to the study of China’s traditional philosophy and ideological history. By reading the data of solar and lunar eclipses recorded by Oracle Bone Inscriptions and combining with astronomical deduction, the solar eclipse occurred on October 31, 1161 BC, which proved that Yin people had mastered the eclipse cycle, which was of great significance to the study of Oracle Bone Inscriptions dating and even the movement of the earth and the sun. Combined with Oracle Bone Inscriptions’s Oracle inscriptions and the inscriptions unearthed from the Shi family cemetery in Shangzhou, Tengzhou, Shandong Province, the landscape of Xue Guo in Shang Dynasty was determined, which provided a new fulcrum for the study of historical geography in Shang Dynasty. The study of Oracle Bone Inscriptions has developed into an international academic topic, with scholars participating in the study all over the world and numerous works, which have played an important role in promoting the spread of Chinese culture and promoting the exchange and mutual learning of civilizations.

　　Zhao Yongfu, president of Naval Equipment Research Institute and executive director of China Shipbuilding Engineering Society, has presided over and participated in many major equipment projects.

　　A series of recent major events and new changes in the Naval Equipment Research Institute closely revolve around a distinct theme-improving the ability of independent innovation in scientific research. In everyone’s eyes, the Party Committee of the Academy, which has just experienced the study and practice activities in the previous stage, is like a "locomotive" with full strength, which drives scientific research and innovation into the "fast lane".

　　Look for problems and dare to poke "pain points"

　　"Independent innovation is the foundation of our demonstration research institution!" This understanding of Liu Mingli, political commissar of the Naval Equipment Research Institute, was written into the "Decision on Vigorously Improving the Ability of Independent Innovation in Scientific Research" recently issued by the Party Committee of the Institute, so as to make it clear at the beginning.

　　During the study and practice of Scientific Outlook on Development, the Institute has grasped the main contradiction that "the ability of independent innovation in scientific research is incompatible with the requirements of fulfilling the mission and responsibilities", and the problem has really hit the "sore spot". Focusing on the fundamental goal of "improving the ability of independent innovation in scientific research", we focused on five aspects, such as top-level design of equipment and demonstration of major models, and made breakthroughs in seven aspects, such as enhancing the ability of macro-demonstration research, cultivating independent innovative talents, and giving play to the core leadership role of the Party Committee in promoting independent innovation. A series of major measures to rectify and implement problems are in full swing …

　　High-level demonstration of research results is the most important thing for research institutes that are revered as "think tanks" and "think tanks" for naval equipment construction and development. The Party Committee of the Research Institute seized the most urgent equipment problems that require the transformation and development of the navy and affect the construction of the navy’s military capability, sorted out and refined six major macro-topics, such as "strategic requirements for the development of naval weapons and equipment", organized elite soldiers to focus on research, and further raised the demonstration research to a high level.

　　The demonstration of equipment capability will ultimately be verified by the actual combat environment. "Sitting in the laboratory and facing the computer", relying solely on this "study-style" demonstration method, is not closely related to actual combat. The research institute tried to establish an "equipment demonstration research base" in a submarine force. Scientific researchers and submarine officers and men went to sea for snorkeling together, used modern simulation methods to deduce subjects such as "underwater information confrontation", and closely combined the demonstration research of equipment capability with the battlefield background of officers and men training, submarine tactics, combat opponents and specific sea areas. Both scientific researchers and army officers and men gained a lot.

　　Create a new model to study big problems

　　"Without a strong academic atmosphere, it is not like a research institute!" Zhao Guoan, deputy director of the Science and Technology Department of the Academy, said that the atmosphere of academic exchanges is not strong and the level is not high, mainly because of conservative leadership ideas and insufficient estimation of the enthusiasm of scientific researchers.

　　Through hard work, the Institute successfully held the Frontier Forum of Naval Equipment Development from September to December last year, invited many academicians and well-known experts to participate, received more than 250 high-level papers, and achieved rich forward-looking and cutting-edge research results. The Naval Equipment Research Institute has also established a joint scientific research model of "small core and big periphery", that is, the institute has mastered the core technology, at the same time recruited scientific research talents and strength for the whole army, strengthened strategic cooperation with scientific research institutes and industrial departments inside and outside the military, established an "innovation alliance" between the military and the ground, and organized a "national team" for equipment demonstration and research.

　　From the initial "a piece of paper, a pen and a slide rule" to the popularization of computers today, the research conditions and means of the Institute have made great progress. However, today’s war is developing faster, and the equipment demonstration research needs more modern simulation methods to describe, preview and reproduce the grand and complex information battlefield, and researchers have a strong voice for the lag of scientific research conditions.

　　Dean Zhao Yongfu described the three-year plan for scientific development: seize the precious opportunity of the state to increase investment in the construction of scientific research conditions in the military, and urge 11 key laboratories to pass the project evaluation and make great strides toward the goal of building a "naval weapons and equipment integrated scientific research center".

　　There is another "big hand" of the Party Committee of the Academy: two years ago, when the family funds were only 20 million yuan, they boldly reformed the management methods of scientific research funds, and raised funds of 240 million yuan to buy an unfinished building for reconstruction, expansion and decoration. Nowadays, the uncompleted residential flats have been transformed into a 20-storey modern scientific research complex with an area of 34,000 square meters, and a key national defense laboratory has been settled here.

　　"Activating" Innovative Talents

　　A "shocking event" happened during the study and practice activities, which made everyone feel the determination and courage of the hospital leaders to "activate" the innovative talent team: in 2008, 18 professional and technical cadres in higher and secondary vocational schools failed in the re-appointment evaluation, and the "elimination rate" was as high as 10%. In view of the lack of independent and innovative talents, the Naval Equipment Research Institute put forward the idea of "six batches" of talent construction: training scientific research leaders to create a batch, selecting a batch from famous universities, recruiting a batch from local scientific research units, supporting a batch with projects and funds, reusing a batch in key positions, and encouraging a batch. Those cadres who have achieved mediocre results and even have not written a paper during their five-year term of office are "out" in the competition for professional title evaluation, which has indeed played a role in "urging a group".

　　Since 2006, the Institute has spent one year to conduct a comprehensive investigation and analysis on the distribution of disciplines and disciplines and the structure of scientific research capabilities of the scientific research team in the whole hospital, and formed a 136-page Research Report on the Structure of Scientific Research Capabilities, in which hundreds of scientific researchers were seated one by one. In view of the existing problems, a number of measures were introduced to strengthen the construction of innovative talent teams. At present, researchers under the age of 35 account for 51% of the research institutes, and it has become a fundamental plan to build an innovative development platform for young people. The Institute has intensively issued documents such as "Implementation Measures for the Selection of New Scientific Research Stars" and "Measures for the Management of Youth Scientific Research Funds". This year, it has allocated 1 million yuan to support 20 innovative projects, and various departments and offices have also actively followed up, and young researchers have signed up enthusiastically.

　　An unprecedented "clean-up" is being carried out in every corner of the organs and departments of the Naval Equipment Research Institute. The contents of the clean-up are all kinds of rules, systems, measures and methods. Party committees and organs study and practice Scientific Outlook on Development, and the "highlight" of rectification and implementation is the construction of innovative mechanisms.

　　According to the eight research reports of the Standing Committee and the opinions and suggestions collected from the whole hospital, the Party Committee of the Institute sorted out 48 innovative measures and issued the Decision on Vigorously Improving the Independent Innovation Ability of Scientific Research, which guaranteed 21 innovative measures that could be put into practice immediately based on the actual situation of the Institute.

　　To this end, the whole hospital has comprehensively cleaned up the existing 216 systems. Among them, 72 items were abolished, 30 items were retained, 94 items needed to be revised, and 20 items urgently needed to be established.

　　Getting rid of the shackles of old ideas makes people walk briskly, and the call for innovation is more hopeful. A number of new systems to support independent innovation in scientific research are ready to emerge, such as "establishing an integrated joint experimental research model", "reforming the evaluation and reward system for demonstration research" and "normalizing high-level exchanges".

　　Scientific development drives innovation and development, like a spring tide, surging endlessly …

　　The "Cultural and Natural Heritage Day" in 2024 is approaching. The theme of this year’s intangible cultural heritage publicity and exhibition activities is "protecting and inheriting intangible cultural heritage, continuing the historical context and writing the chapter of the times". Compared with last year’s "Cultural Relics Protection and Utilization and Cultural Self-confidence and Self-improvement", this theme highlights the historical dimensions of protection and inheritance, that is, past, present and future. Continuing the historical context focuses on making intangible cultural heritage better come out of history, and writing the chapter of the times is to make intangible cultural heritage better enter a new era and move towards the future.

　　It is our expectation for the intangible heritage, and it is also the starting point and the foothold to protect and inherit the intangible heritage. After all, the intangible cultural heritage is not only the trace and witness of the past life, but the "root" and "soul" left by our ancient nation to the present and the future, bearing incalculable historical and cultural values. For these intangible heritages with diverse categories, wide fields and rich contents, they are a sensible and experienced "skill" or a meaningful life that can be participated in and realized; Deep down, they are a cultural epic, engraved with the spiritual "code" of our Chinese civilization; From a distance, it is a collective memory about the production and life of ancestors and the exchanges and exchanges between ethnic groups, bearing the heavy responsibility of casting a solid sense of the Chinese nation’s community and helping the great rejuvenation of the Chinese nation.

　　Let the intangible heritage go out of history, into the present and into the future, which can neither be achieved overnight nor once and for all. We must follow the law of intangible heritage protection and inheritance, protect it with initial heart, inherit it with ingenuity, and develop and utilize it with awe.

　　To protect the intangible heritage with the initial heart, we must let the intangible heritage return to "life" and reproduce the "truth". Non-legacy is to life what live fish is to rivers. Every intangible cultural heritage is not a fragment of production and life, but a complete and organic production and life, which is the daily life of people and things in a specific "scene". To protect the intangible cultural heritage with the initial heart and practice the concept of "seeing people, seeing things and seeing life", it is necessary to let the intangible cultural heritage return to the "scene", make it participate in production and life again, and become one of the "protagonists" of the cultural habitat again. The ancient city of Zhangzhou, Fujian Province, which won the "Model Award for China’s Human Settlements", has a history of more than 1,000 years and a protected area of 53 hectares. At present, more than 20,000 residents still live in traditional houses with red "smoke-baked bricks". Tasting Fujian tea and chatting about the daily life of the ancient city has attracted more than 60 cultural formats with non-legacy and old craftsmanship to settle here. This is the dynamic preservation of inheriting history and continuing life, the vivid practice of "seeing people, seeing things and seeing life", and the concrete embodiment of guarding the intangible heritage with the initial heart.

　　Inheriting the intangible heritage with ingenuity, we must adapt the intangible heritage to the present and highlight the "true color". Every non-legacy has a touching story, and each story reflects the diligence and courage of the Chinese nation and the wisdom of transforming nature and social life. Folk literature, traditional drama and other intangible styles directly record the history, continue the context and nourish the folk culture. Inheriting the intangible heritage with ingenuity means persisting in innovation, grasping its "essence" and keeping its characteristics in the process of active innovation, pursuit of perfection and creation of fine products, and continuously enhancing the attraction of intangible heritage in iterative upgrading. In recent years, on the basis of retaining the characteristics and essence of traditional art, Henan operas have constantly innovated their programs, and launched modern Henan operas such as Jiao Yulu and Li Tiancheng, a village official, and the innovative musical Faith, which won the audience’s love and made the "old tree" of non-legacy operas sprout, add vitality and highlight its true colors. This is the result of ingenuity in intangible heritage, the result of ingenuity and intangible heritage "two-way trip", and the result of upholding awe, following the law of intangible heritage development and rational development and utilization.

　　To develop and utilize intangible cultural heritage with awe, we must follow the law and show our "skills". Every intangible heritage is a "living history" left to future generations, bearing the hard exploration achievements of the Chinese nation from generation to generation. Intangible heritage, as a cultural event that originated from ancient life and continued through history to today, has its own characteristics and laws. The process of developing and utilizing intangible heritage is not only a process of grasping the law of intangible heritage, protecting and inheriting intangible heritage according to the law, but also a process of activating the vitality of Chinese excellent traditional culture with the spirit of the times. To develop and utilize intangible cultural heritage with awe, we should focus on "deciphering" intangible cultural genes and spiritual codes, open a new channel through history and the future, connect with the powerful "context" and endless "motive force" bred by China’s millions of years of human history, 10,000 years of cultural history and 5,000 years of civilization history, explore and show intangible "skills" and help the great rejuvenation of the Chinese nation. To develop and utilize intangible cultural heritage with awe, we should not only focus on improving the cultural and ecological environment from the big picture, but also focus on "embroidery" from the small details, fully tap the historical and cultural heritage behind intangible cultural heritage, integrate historical culture with modern life, and make intangible cultural heritage truly become a daily life for the people and a "source of living water" facing the future.

　　Intangible heritage is a precious gift left by ancient people, a unique cultural memory of human beings and a dynamic "living life", which plays an extremely important role in serving the people’s livelihood and helping to build a strong cultural country. On the occasion of "Cultural and Natural Heritage Day", we should focus on the theme of "protecting the heritage, continuing the historical context, and writing the chapter of the times", reiterate the preciousness of the initial heart, the importance of ingenuity, and the key to awe, and re-understand the concept of "seeing people and things and seeing life" and the policy of "protection first, rescue first, rational utilization, inheritance and development" in order to further form.

　　On the 28th, the reporter learned from the Guiding Opinions on Early Warning and Management of Liquidity Risk of Housing Provident Fund Funds in Guangdong Province issued by the Provincial Department of Housing and Urban-Rural Development that Guangdong will establish an early warning and management system for liquidity risk of housing provident fund funds.

　　According to the requirements of opinions, through the early warning indicators of individual housing loan rate and net capital flow of housing provident fund, we will comprehensively analyze the capital flow of housing provident fund in time and predict the development trend of supply and demand of housing provident fund loans, and implement early warning in the city as a unit. At the same time, the implementation of early warning classification management. According to the operation of funds and referring to the relevant provisions of the state, 85% of the individual housing loan rate of housing provident fund is set as the critical point of early warning, and it is divided into three early warning levels according to the early warning level: the first warning is that the individual housing loan rate of housing provident fund is between 85% and 90%, and the net flow of funds is negative for three consecutive months; The second warning is that the personal housing loan rate of housing provident fund is between 90% and 95%, and the net flow of funds continues to be negative; The third-level warning is that the personal housing loan rate of housing provident fund is above 95%, and the net flow of funds continues to be negative. When the two early warning indicators of individual housing loan rate and net capital flow meet the conditions at the same time, the corresponding early warning level is triggered.

　　The opinion calls for early warning and management of capital liquidity risk. The Provincial Department of Housing and Urban-Rural Development has established a monthly housing provident fund system through the relevant data of the housing provident fund statistical information system and other relevant data, carried out analysis on the operation of relevant business indicators, monitored the liquidity risk of housing provident fund funds in various cities, and issued early warning risk tips to urban housing provident fund management committees and housing provident fund management centers when necessary. Municipal housing provident fund management centers should establish and improve the liquidity risk prevention and control mechanism, strengthen the research and judgment on the liquidity risk of housing provident fund funds, formulate the implementation plan for the liquidity risk prevention and control of housing provident fund funds, and take corresponding control measures to prevent and control risks according to the early warning level. When the risk warning is triggered, it should be reported to the housing provident fund management Committee and the provincial competent department in time, and corresponding measures can be taken to prevent and control risks.

Since the launch of the end-to-end intelligent driving system "FSD V12 beta" in the United States in August 2023, end-to-end has become the hottest topic in the automobile industry. With the follow-up of Huawei, Tucki, Weilai, Ideality and other enterprises, almost every domestic manufacturer will spend a lot of space in the press conference to publicize how powerful their end-to-end is. Regardless of marketing methods, what does "end-to-end" mean? What does it mean for intelligent driving? Today we will explain this question to you!

Before the end-to-end intelligent driving system was mass-produced, every intelligent driving system adopted a modular scheme. Simply put, modular intelligent driving is an assembly line, which mainly includes four processes: perception, prediction, planning and control. First of all, the task of the sensing part is to process the data of sensors such as radar and camera of the vehicle, and then analyze the specific position and road trajectory of the objects around the vehicle, and distinguish whether they are pedestrians, bicycles, cars or trucks.

Then, the perception module will transmit the above information to the prediction module, and the prediction module will analyze the next movement state of the surrounding traffic participants according to the above information, such as whether the surrounding vehicles will turn, go straight or stop next. After further analysis, the prediction module will provide one or more driving paths and vehicle speeds that the vehicle can refer to next.

Then the prediction module sends the road driving scheme of the vehicle to the planning module, and the planning module will decide what the vehicle should do next according to the information such as the vehicle’s own state and navigation. After the planning module confirms the driving path and speed, it will transmit the command to the control module, and then the control module will calculate and operate the steering wheel, brake and throttle of the vehicle. A seemingly simple intelligent driving function is realized through the above steps.

From the above introduction, it is not difficult to see that modular intelligent driving decomposes simple driving behavior into multiple steps, and the logic of each step is in perfect harmony. In the eyes of car companies and suppliers, modular intelligent driving itself is a very good solution, because different teams can be responsible for the corresponding modules and give full play to the advantages of division of labor and cooperation, thus rapidly changing intelligent driving from concept to mass production.

Secondly, modular intelligent driving has a set of system framework with clear functions and responsibilities, so when the intelligent driving system finds bugs in use, car companies and suppliers can immediately find the specific reasons for the bugs and quickly fix them through OTA. For example, if the vehicle brakes wrongly when driving at high speed, then through data analysis, the vehicle enterprise can know whether the fault is due to the wrong data of the sensing module or the wrong judgment given by the forecasting and planning module.

Although modular intelligent driving is convenient for mass production and BUG repair, it needs to learn a lot of traffic rules and driving experience if it wants to control vehicles like people, and all this depends on engineers to define the rules in advance, that is, to turn traffic rules and driving experience into lines of software code. But can engineers write code to cover all the driving scenes in reality? Of course it’s impossible! On this issue, there is a classic case in the industry. If you drive a vehicle on a narrow road full of cars on both sides, a balloon suddenly floats on one side of the road, then the general logic will think that there may be children jumping out on one side of the road, so the vehicle should brake immediately. However, the same scene is placed on the high speed. If the intelligent driving system still controls the vehicle by braking immediately, it is likely to turn into a rear-end collision. In other words, if engineers don’t define the rules in advance for this kind of driving scene, such as the system doesn’t brake after the balloon is detected at high speed, then the intelligent driving system will have safety risks when it encounters similar scenes.

According to Xpeng Motors, a relatively stable mass production intelligent driving system has about 100,000 rules. And if the intelligent driving system is to be close to the same level as people, it needs to manually write about 1 billion rules. For software engineering development, this is almost impossible. Because of this, we can see that the traditional intelligent driving system will make more or less mistakes in daily use, so that drivers have to intervene.

For the above reasons, car companies that focus on autonomous driving have been trying to solve the problem that traditional intelligent driving needs preset rules, so there is an end-to-end approach. The so-called end-to-end, in fact, is to make all the traditional sub-modules of perception-prediction-planning-control neural network, that is, to replace the traditional algorithms and manually written rules with advanced algorithm models.

Therefore, the end-to-end workflow is quite different from the traditional modular workflow. The traditional modular work sequence is perception-prediction-planning-control in turn, while the end-to-end sequence is sensor data (radar, camera)-neural network-driving parameters (steering wheel, throttle, brake), that is to say, the traditional perception, prediction, planning and control modules are all completed by neural network.

As can be seen from the workflow, the core technology in end-to-end is neural network, and the technology most closely related to neural network is AI. In the past two years, AI has shown great performance in the fields of voice, text, pictures and video, and everyone should have realized it. When the neural network is applied to the car, it means that people can constantly train the intelligent driving system, so that it can learn to adapt to more complex driving environment.

Therefore, at the functional level, the biggest change from end to end is that the system has the ability of autonomous learning, which is a function that traditional modular intelligent driving does not have.In this way, when dealing with all kinds of unexpected real driving scenes, end-to-end can calculate the appropriate rules through neural network, without having to manually write the rules in advance, which also provides a solution for intelligent driving to deal with endless driving scenes in reality.For example, the Tesla FSD V11 version, which didn’t have end-to-end function before, has written more than 300,000 lines of code, while the end-to-end FSD V12 version has directly reduced more than 300,000 lines of code to 2,000 lines, but the performance of FSD V12 is closer to human drivers than V11.

fromIn theory, end-to-end is indeed a very ideal technology, but in practice, end-to-end is not so reliable. This is because people’s understanding of neural networks is still not clear enough at this stage, so people also call neural networks "black boxes". As shown in the above figure, in the white box state, we are very aware of the logical causal relationship between system input/output, but when the input information passes through the black box, people can’t explain why the input information becomes the output information.

For example, when there is an obvious logical error in the intelligent driving system, the vehicle manufacturer can quickly find out which module the problem is, and then manually write a new rule. But in the end-to-end system, car companies do not know which parameter or structure in the complex neural network has problems.

For this reason, the end-to-end intelligent driving system based on neural network can sometimes give reasonable rules in very complicated scenes, but sometimes it will make very low-level mistakes, such as not being able to distinguish traffic lights, so some people describe it as "the upper limit is very high and the lower limit is very low". Considering that there are some risks in the end-to-end application, the end-to-end intelligent driving system introduced by Huawei and Tucki does not rely entirely on autonomous learning, and their end-to-end systems still have many manually written rules to cover the intelligent driving system.

From the perspective of technology development trend, end-to-end is definitely the direction of high-level intelligent driving in the future. However, because people’s understanding of neural networks is not thorough enough, the end-to-end performance of various companies at this stage still has a certain gap with the ideal level. In addition, compared with the existing modular intelligent driving system, whether the end-to-end neural network algorithm model is smart or not depends heavily on massive real data for training. Only after massive data training, the neural network can be transformed from a small model to a usable large model, which means that high-order intelligent driving requires huge computing power and data input in the development stage, thus invisibly raising the threshold of intelligent driving. Because of this, some car owners will feedback that their cars are not as good as they used to be after upgrading to end-to-end intelligent driving. This is the painful period of big model training. Considering that there are great differences in end-to-end training among different brands in reality, this means that the performance gap of different brands of intelligent driving systems may be gradually widened in the future.
