Hong Kong mob pistol has a mystery: American rough assembly can not be traced back to the source, and it is easy to frame the police.

[Text/Observer Network Wang Shichun]

On December 8, Hong Kong police seized a large number of dangerous weapons, including a compact glock)19/23 pistol and 105 rounds of ammunition. The bullets of this type of pistol are basically the same as those of the active pistol of the Hong Kong Police.

Military commentators of Observer Network judged that this gun was not a legitimate gun produced by Glock’s original factory, but a "black gun" assembled by American manufacturer Polymer80 products, without any logo, number and ballistic record. Although the product sold by Polymer80 is a semi-finished blank, the gun body has been processed to 80%, and the mob may smuggle the rest of the parts "processed with materials" and finally assemble this black gun.

If the mob used this gun to open fire in the crowd, then the Hong Kong police could not produce the ballistic record of this gun in the subsequent investigation. Today, with the intensification of conflicts in Hong Kong, if the Hong Kong police can’t produce ballistic records for a long time, it is bound to be framed by mobs and put the Hong Kong police at a disadvantage.

The real guns and magazines seized are from Hong Kong media.

Hong Kong TVB TV reported on December 8 that 75 police officers from the Organized Crime and Triad Bureau of the Hong Kong Police raided 11 addresses in Hong Kong and smashed a criminal gang in the early morning of the 8 th. During the illegal assembly in Mong Kok on October 20th, the gang used petrol bombs to attack the Mong Kok Police Station.

In the end, the Hong Kong police seized a large number of dangerous weapons in the mob’s home, including a compact glock)19/23 pistol and 105 bullets. Among them, three magazines are full of bullets. Li Guihua, Senior Superintendent of the Organized Crime and Triad Bureau, said that the Hong Kong Police Force had received a tip earlier that "(this gang) plans to use firearms to create chaos in today’s assembly and procession, including shooting police officers or framing police officers to hurt passers-by".

After studying by military commentators of Observer Network, the mob has a "black gun" modified from Glock 19/23 blank made by American manufacturer Polymer80.

Polymer80 is a company specializing in the manufacture of rough firearms within the scope of "permitted by American law". The rough produced by the company can circulate freely in the market without registration even if there is no serial number.The company’s pistol is characterized by no marks, numbers and ballistic records. The Hong Kong police can’t find available information through the ballistic records and serial numbers of firearms.Only through time-consuming and laborious criminal investigation can the source of guns be traced back.

It is worth mentioning that when Polymer80 sells gun blanks, it not only includes rough blanks, but also small parts, clamping fixtures and necessary drill bits. On the official website of Polymer80, there are also documents that teach you how to process it step by step to the usable level.

Glock in the hands of thugs is a product numbered PF940C. Although it is a rough imitation of the compact Glock 19/23, the machining degree has reached 80%, and all the basic parts of the sleeve seat have been machined, while the sleeve, trigger and barrel are sold separately.

The sleeve seat set is priced at $160, and another sleeve and barrel with high completion is priced at $450, but it shows that it is out of stock. Source: Polymer80 Company official website.

Glock pistol is one of the largest selling pistols in the world, so the parts of this pistol are not hard to find. In Southeast Asia, where gun crimes are frequent, many small weapons factories also independently produce the whole gun and parts of Glock pistols. Mobs may use parts smuggled from abroad to assemble a "black gun" without any marks, numbers and ballistic records.

The underground gun workshop in the Philippines is producing the American-made M1911 pistol, but it is not difficult to produce Glock’s parts.

At present, the Hong Kong police have two types of Glock, namely glock 17 and Compact Glock 19, which are currently used by the Hong Kong Police Small Boat Division (Maritime Emergency Response Team), Witness Protection Team, vip protection unit, Tracking Support Team, Airport Special Police Team, Railway Emergency Response Team, Counter-Terrorism Special Service Team and Special Task Company.

Due to the formal introduction channels, every Glock pistol of the Hong Kong police has a clear ballistic record.

Gun experts told Observer.com that if the mob framed the Hong Kong police with this gun, the Hong Kong police could not produce the ballistic record of this gun in the follow-up investigation. Today, with the intensification of conflicts in Hong Kong, if the Hong Kong police can’t produce ballistic records for a long time, it is bound to be hyped by mobs and framed at a disadvantage.

The Hong Kong police are investigating the purpose of the mob holding a gun. Li Guihua said that this is the first time that the Hong Kong police have seized real guns since the "chaotic demonstrations in Hong Kong", so they are very nervous. The source of this real gun will be one of the focuses of the Hong Kong Police Force’s close investigation in the future.

He stressed that this pistol is not a specification used by the Hong Kong Police Force. When someone asked at the press conference whether the perpetrators tried to frame the plainclothes police in Hong Kong this time, Li Guihua said, "I dare not say more now."

Hard-core New Choice Try SAIC MAXUS D90 Pro Diesel Edition

  [car home Original Test Drive] On April 10th, SAIC MAXUS D90 Pro (abbreviated as D90 Pro in the text) was officially launched, and there were seven new models with the price range of 179,800-279,800 yuan. In fact, this car was unveiled at the Guangzhou Auto Show last year and accepted the reservation. After more than four months, it finally came. We also conducted a field test drive for this car at the first time. Compared with our AH-100 professional test site, the off-road test site is not difficult. Surely such a simple "test" can’t help this "tough guy" who is good at off-road?

Home of the car

  The test drive of the SAIC MAXUS D90 Pro is equipped with a 2.0T diesel engine and matched with the 8AT automatic manual transmission. As a modified model of SAIC MAXUS D90, this car has also been given a brand-new naming method. The appearance of the word Pro makes us look forward to the improvement of its strength.

● Test drive models

  Although it is said that there are seven models on the market, in fact, there is no fixed configuration version of the D90 Pro. The "recommended models" and prices are only for reference. Users can determine the configuration they want through the wise selection of SAIC MAXUS Spider, and specifically customize their favorite models.

● The appearance is masculine.

  The body size of the D90 Pro is relatively large, which also determines that it is "born" with a strong gas field. The hexagonal mesh shape looks a bit exaggerated, but at present, "big mouth" is also a popular design style. For most users who choose the D90 Pro, they definitely bought a car to go out in the wild, so it is more important to choose a set of off-road kits. The off-road kits provided by SAIC MAXUS for the D90 Pro include original 18-inch off-road tires, wading throats, bottom off-road fenders, off-road wheel eyebrows and sand barriers, etc. The D90 Pro equipped with these kits is like an athlete in a competition suit, and its heroic spirit is compelling. It’s a little pity that we didn’t assemble all the off-road kits for this test drive.

  Compared with the competitors of the same level, the body size of the D90 Pro does not fall in the wind, and the wheelbase length is obviously superior to that of the competitors of the same level. As a car with off-road capability as its selling point, the passability is a very important indicator. The minimum ground clearance of D90 Pro is 210mm, and the maximum wading depth is 800 mm. The low point of the chassis uses a waterproof one-way valve, and the approach angle is 28, and the departure angle is 25, so it will not easily rub when facing complex road conditions.

  The design style of the interior is quite fashionable. When you only look at the interior, it is hard to imagine that this is a medium-sized off-road vehicle. The silver decorative strips in the details, the large-area suede material coverage and the 12.3-inch central control screen all show you: "Although I am big, I can be exquisite."

  The 12.3-inch central control screen is not so big in the current trend of big screen popularity. It feels just right on this car, and the clarity of the screen and the fluency of the system response are good. SAIC Ali Zebra Zhixing system can be said to be an "old friend" of everyone. Now this system has been upgraded to version 3.0, with more and more functions, including voice control, music, navigation, remote control of vehicles and other functions. The original car is also equipped with a high-tech navigation map.

  The seat configuration of this test drive model is quite high. With the help of Spider Smart Choice, the rich seat functions are no longer exclusive to the top model. Users can customize their favorite configurations according to actual needs, and the diversified seat layout forms also give consumers more choices.

● Summary

  In fact, there is not much to describe about the static part. The exterior design and interior design are two separate things, and it is most important for users who really want to buy a car to look pleasing to the eye. The spider intelligent selection function launched by SAIC MAXUS has raised the user’s independent choice to a new height. This intelligent customization service provides nearly 100 choices including powertrain, seat form, appearance kit, interior material and configuration equipment, and can directly place orders with the factory, and can also track the manufacturing status of the vehicles it has ordered in real time. With this feature, you will avoid a lot of time entangled in the configuration table.

● Power system

  The 2.0T diesel engine mounted on the D90 Pro is named SAIC π (meeting the national VI b emission standard). This engine adopts two-stage supercharger, which can exert the maximum value of turbocharging under different load intensities, and has obvious effect on improving the low-speed torque of the engine. In addition, the friction work of the piston at medium and low speed is reduced by staggering the crankshaft centerline and the cylinder bore centerline, which is beneficial to improving fuel economy and reducing noise.

  The so-called all-terrain intelligent timely four-wheel drive system is actually several torque output forms calibrated by manufacturers according to different road conditions and the conclusion of road test. If you are a "super hard core" cross-country player, you can also choose to install the part-time 4wd system. In terms of gearbox setting, this gearbox will not shift up automatically in manual mode, so as to ensure stronger torque output in low-speed gear and cope with more complicated off-road conditions.

  The D90 Pro has smooth power and sensitive throttle adjustment. Although the size of the whole vehicle is not small, it doesn’t feel heavy when driving, and there will be no hesitation even when completing cross-country projects. During the test drive, for safety reasons, parking on the slope is not allowed at the site, so there is no difficulty in completing the climbing project (about 40 slope).

  The overall texture of the chassis is relatively compact, the support effect of the suspension is good, it is somewhat tenacious, and the handling of bumps on the road surface is relatively simple. When walking on the continuous undulating road surface, the rear suspension has no obvious redundant ricochet, and there will be no feeling like sailing. The steering system in the form of electronic power is exchanged for a lighter steering feel, and driving in daily urban traffic environment will not feel tired.

  The suspension stroke of the D90 Pro is relatively long, and the ground clearance is enough, so it is more calm when facing the shell pit, and the phenomenon of bottoming will not easily occur. The wheel-to-wheel slip restriction effect is excellent, the response is rapid, and it is easier to pass.

  Two "opponents" were also found at the scene, and I experienced Haval H9. The overall feeling of Haval H9 is more "tight". From the chassis texture to the steering feel to the feeling of the accelerator pedal, H9 is more "hard", but the low-torque dynamic performance is better than D90 Pro. Like an athlete on the basketball court, H9 is like a center, heavy and slow, but as long as the action is in place, it must be an effective action; The D90 Pro is more like a power forward, with more agile performance and richer actions and means of "scoring". The setting of each project in the off-road test drive venue is relatively simple, and both cars can pass easily, so it is impossible to tell the absolute advantages and disadvantages in this competition.

● Summary

  SAIC MAXUS D90 Pro is a car with high attention, which can be seen from the fiery degree of car home Forum. Through the spider intelligent selection function, users can have a high degree of "autonomy", which is undoubtedly a good thing. A short field test drive can’t have a deep driving experience for this car, but as far as the test items in the field are concerned, no one can stand the D90 Pro hard, which can also prove that the off-road ability of the D90 Pro is really good. Next week, we will welcome the D90 Pro test car. At that time, we will pull it to a professional off-road field in car home for the AH-100 off-road test, and then we will see how its "real strength" is. (Text/map/photo by car home Fu Bo)

Gree air-conditioning encounters dealers donating money to run away. Will Gree take responsibility?

Original title: Gree air-conditioning encounters dealers donating money to run away. Will Gree take responsibility?

Not long ago, it just broke the news that Vantage dealers lost contact. Now, Kunmeng Decoration, a distributor of Gree air conditioners in Hangzhou, has run away again. The boss is a "post-90 s" boy. Since the Dragon Boat Festival Holiday Notice was issued on June 16, he has never opened the door again.

Gree air-conditioning encounters dealers donating money to run away. Will Gree take responsibility?

According to the complaint register of Hangzhou Agile International Garden, a community that suffered major losses, 77 owners were cheated, most of them paid 10,000-20,000 yuan, and the largest single loss in the register was 820,000 yuan, including renovation and installation costs. Most of them are Gree air conditioners, but there are also a few Daikin air conditioners and Haier air conditioners. According to qianjiang evening news reporter’s preliminary statistics, the total loss amount is nearly 2.5 million yuan. Of course, this is not a complete statistic.

What does the decoration of Kunming League have to do with Gree?

In the shop decorated by Kun Meng, there are two brands of Gree authorized retailers:

1. "Hangzhou Tiancheng Air Conditioning Engineering Co., Ltd." specially authorizes "Hangzhou Kunmeng Electric Appliance Co., Ltd." as the designated retailer of Gree Central Air Conditioning in Hangzhou.

2. "Gree central air-conditioning factory authorized direct-sale store", valid from October 2017 to July 2018.

Hangzhou Tiancheng Air Conditioning Engineering Co., Ltd. is a supplier and after-sales service provider of Gree central air conditioning in Hangzhou. Gree customer service also indicated that Hangzhou Kunmeng Electric Appliance Co., Ltd. is indeed a distributor of Gree air conditioning, and it was authorized by Hangzhou Tiancheng to pick up the goods in Tiancheng.

Does Gree need to take responsibility?

As the authorized party of Kunmeng Decoration, Tiancheng Air Conditioning said that it has given a solution for the owner: providing equipment and construction personnel with compensation to solve the engineering problems left by Kunmeng first, but it needs to be charged, and the detailed agreement price is listed in the plan. In the scheme, with a period of one year, Tiancheng cooperated with the owner to recover the cheated amount. If it is recovered, the owners will make up for it according to the listed agreement price. If it is not recovered, it will be made up at 15% off the agreed price.

For Tiancheng’s solution, most owners don’t recognize it: "Why should we spend money again? Don’t Tiancheng and Gree have any responsibility? "

At present, Gree headquarters has not expressed its position on this matter.

From this point of view, whether Gree or Tiancheng Air Conditioning has awarded the dealer qualification after inspecting the dealer qualification of Kunmeng Decoration, then the air conditioning enterprise and the dealer should share the responsibility.Gree, as a well-known air-conditioning brand in China, should be responsible for its distributors and consumers to some extent..

Dealers running away will obviously harm the interests of all parties, first of all, ordinary central air-conditioning buyers, and secondly, all the employees in the store, which will certainly do great harm to the brand in this area.

But in any case, this tragedy that has brought harm to many people should be avoided by all parties, especially manufacturers, and once it happens, manufacturers should be duty-bound to bear some responsibilities. In the face of the victims who are already in dire straits, it is the brand’s heavy sense of responsibility and shining brand image that may be pulled up.

From the North Pole to the Universe, The Adventure of the Haier Brothers Universe has been launched.


1905 movie network news Twenty-three years ago, the animated film Haier Brothers came out, which became the first popular science animated feature film in China, and made a great contribution in the history of original animation in China. Twenty-three years later, the new animated film "The Adventure of Haier Brothers" moved the story background to the space and continued to lead a new generation of children and audiences to explore unknown mysteries. The play premiered on Tencent Video, Iqiyi and other platforms on September 17th, and was updated at 16:00 every day from Monday to Friday.


Stimulate imagination and explore spirit


The Haier brothers once crossed the North Pacific Ocean, went deep into the Arctic, got to know Eskimos, witnessed the wonderful phenomena of nature such as extreme daylight and mirage with their own eyes, and completed a global adventure with friends. This cartoon has far-reaching educational significance, is entertaining and won the audience’s love. It won the Golden Boy Award and the Golden Eagle Award successively, and became an excellent original children’s cartoon in China in the 1990s.


In this new animation, the Haier brothers remain unchanged, and as always, they stick to the main line of transmitting knowledge and inspiring imagination, and take accompanying children to grow up healthily as their mission. Haier Brothers Cosmic Adventure focuses on knowledge and exploration, not telling children the standard answer or "what", but encouraging children to actively seek knowledge and explore "why". In the Haier Brothers’ world, every child is "unique", and the purpose is to respect children’s interests, stimulate their imagination and exploration spirit, and let them develop their personality and wisdom.


This time, the Haier brothers are going to explore the vast universe, get in touch with powerful intelligent creatures and alien civilizations, and lead children to see more cutting-edge technology, which will greatly broaden their horizons. At the end of each cartoon, there is a small knowledge class, such as "How big is the universe" and "What is a nano-robot", which transforms the storyline mentioned in the feature film into small knowledge of popular science. This knowledge transfer based on the plot is more enlightening than blunt indoctrination, which can be described as the integration of wisdom and interest, which will greatly broaden children’s knowledge and acceptance.


Realize self-transcendence


Haier brothers subverted the traditional creative mode.Before the production of "Haier Brothers Cosmic Adventure", it was convenient to interact with small audiences on the material, character design and content of the animation, and went to primary schools and kindergartens in many cities to have face-to-face communication with children, and guided the design and production of cartoons according to the voting results. This kind of interactive creation subverts the closed production mode of traditional cartoons, connects producers and users, draws inspiration and suggestions from the target audience, and creates fine products that the audience loves and recognizes.

  Moreover, there is a heating device in the globe, and the temperature decreases from the equator to the poles, so blind children can better understand geographical knowledge.

Experts’ Interpretation of the Technical Guide for Derivation of Marine Biological Water Quality Standards (Trial)

  In order to protect the marine environment and promote the work of marine environmental standards, the Ministry of Ecology and Environment issued the Technical Guide for Derivation of Marine Biological Water Quality Standards (Trial) (HJ1260—2022) on July 18, 2022 (hereinafter referred to as the Guide). This is the first standard to guide and standardize the derivation of marine environmental standards in China, and relevant experts have answered relevant questions.
  Q: What is the significance of the publication of the Guide for China’s marine environmental protection?
  Researcher Yao Ziwei of National Marine Environmental Monitoring Center: Marine environmental benchmark is an important part of modern ecological environment governance system, and it is the basis and scientific basis for formulating China’s marine ecological environment quality standards, which can provide important support for China’s marine ecological environment risk assessment and emergency response.
  The current Standard for Seawater Quality (GB3097—1997) has played an important role in the prevention and control of marine pollution in China, but when the standard was first formulated, it was based on one or more foreign seawater quality standards (marine life, senses, health, etc.). As for marine biological water quality standards, there are great differences between different countries and even the same country in different periods due to the differences in derivation methods and concerned species. When conditions permit, countries should carry out relevant benchmark research according to their own marine ecological environment characteristics.
  The publication of the Guide is of great significance for strengthening the research of marine environmental standards in China, accelerating the transformation and application of research results, and improving the level of marine ecological environmental protection.
  Q: Since the 1980s, some developed countries and international organizations have successively issued water quality standards for marine organisms. In contrast, what are the unique features of the Guide in terms of methods and technical requirements?
  Researcher Wang Ying, National Marine Environmental Monitoring Center: Since 1980s, the environmental management departments of the United States, the European Union, the Netherlands, Australia/New Zealand and Canada and other countries and international organizations have successively issued technical guidelines for deriving water quality standards for protecting aquatic organisms (freshwater organisms and marine organisms) and water quality standards for protecting marine organisms according to their environmental management needs and water pollution status. In the process of compiling the Guide, domestic and foreign scientific research achievements were fully absorbed and used for reference.
  Methodologically, it is stipulated that the species sensitivity distribution method is used to derive the water quality standards of marine organisms, which is the mainstream method to derive the water quality standards of freshwater and marine organisms in the world at present, and it is also the method stipulated in the Technical Guide for Deriving Water Quality Standards of Freshwater Organisms (HJ831—2022).
  In terms of technical requirements, the characteristics and working basis of China’s marine ecosystem are fully considered: first, the toxicity data of marine species in China are required to be used to derive the water quality standards of marine organisms; Secondly, according to the species distribution of marine ecosystems in China, the minimum toxicity data requirements of "5 families and 8 species" based on the characteristics of marine biota in China are put forward; Thirdly, the calculation method of acute value/chronic value of the same effect is proposed, which solves the problem that different types of toxic effects have different weights and achieves the purpose of better protecting marine species in China. At present, only the European Union has put forward this technical requirement internationally.
  Q: How to consider the minimum toxicity data requirements of "8 species in 5 families" based on the characteristics of marine biota in China?
  Yan Zhenguang, researcher of china environmental science Research Institute: According to statistics, there are more than 3,000 species of microalgae and macroalgae in China, accounting for 11% of the total marine species in China; Arthropoda, Chordata, Annelida, Mollusca, Echinoderm and Rotifera are the main animal groups in China’s sea areas, with more than 17,000 species, accounting for 59% of the total marine species in China. The number of marine species in the above key groups of marine life in China accounts for more than 70% of the total marine species in China.
  In order to make the derivation of marine biological water quality benchmark reflect the characteristics of marine ecosystem in China, it is a basic principle to determine the minimum toxicity data requirements for the derivation of the benchmark. The tested species in seawater should cover the key groups of marine organisms in China, which is embodied in the following aspects: 1 family of microalgae or macroalgae, 2 families of crustaceans in Arthropoda and 1 family of bony fishes in Chordata; Other phylum, such as annelids, molluscs, echinoderms, rotifers, etc., or an unused family among crustaceans and teleost fishes.
  The minimum toxicity data requirements of 8 species are mainly considered from the following two aspects: from the point of view of mathematical statistics, the more species, the better the model effect; From the point of view of the robustness of species sensitivity distribution model and the reliability of reference value, if the toxicity data covers key biological groups, then the uncertainty of reference value based on more than 8 species is within the acceptable range. There are eight criteria for evaluating the number of species as "good" in the minimum toxicity data requirements of the Australian/New Zealand Technical Guidelines for Derivation of Water Quality Standards.
  At the same time, from the perspective of protecting marine biodiversity and marine ecology, it is clear that alien invasive species should not be used as a benchmark to deduce the tested species, such as marine microalgae that produce microcystins and Spartina alterniflora that compete with native species for nutrition.
  Q: We have noticed that there are great differences in the exposure time of different kinds of marine life in the Guide. How do you consider it?
  Professor Tan Qiaoguo of Xiamen University: Based on the standard testing methods of marine ecotoxicology at home and abroad, in order to protect marine species in China more pertinently, on the basis of analyzing the life history and reproductive characteristics of different types of marine species, the Guide puts forward the differential exposure time for 7 categories and 43 families of marine organisms such as algae, rotifers, annelids, molluscs, arthropods, echinoderms and chordates. According to the acute toxicity test, the generation cycle of Brachionus plicatilis is only about 2 days, and it is recommended that its exposure time should not be longer than 48 hours. For most arthropods and fish, the generation cycle is long, and the exposure time is recommended to be no more than 96 hours. According to the chronic toxicity test, the generation cycle of cladocera such as Daphnia mongolica is 5-7 days, and the exposure time is recommended to be no less than 5 days. However, the generation cycle of fish such as medaka can reach 3-4 months, and it is recommended that its exposure time should be no less than 21 days.
  Q: As the vice chairman of the National Expert Committee on Environmental Standards, I would like you to talk about what work needs to be promoted in the field of marine environmental standards in China during the 14 th Five-Year Plan period.
  Researcher Wang Juying, National Marine Environmental Monitoring Center: Marine environmental standards mainly include marine biological water quality standards and sediment quality standards for protecting marine ecosystems, nutrient standards for preventing water eutrophication, and people’s health standards for consuming seafood and marine recreational water.
  China’s marine environmental benchmark research began in 1980s, and made some progress. For example, related research provided direct technical support for the formulation of Marine Sediment Quality (GB18668—2002); The national "863" special project "Research on Key Technologies for Determining the Threshold of Marine Environmental Effects of Typical Organic Pollutants from Land-based Sewage Discharges into the Sea" and the marine public welfare scientific research special project "Research and Formulation of Offshore Seawater Quality Standards/Standards" won the first prize and the second prize of the Marine Engineering Science and Technology Award respectively.
  China’s sea area spans temperate zone, subtropical zone and tropical zone, and the marine ecosystem is diverse. From the perspective of protecting China’s marine ecosystem, during the Tenth Five-Year Plan period, based on protecting the integrity of China’s marine ecosystem, we should speed up the research and construction of China’s seawater quality benchmark system, develop the target pollutant marine biological water quality benchmark that has an important impact on China’s marine ecological environment quality, carry out the ecological risk threshold research of new pollutants such as endocrine disruptors, and develop the nutrient water quality benchmark of key sea areas such as Bohai Sea and South China Sea based on classification and zoning.
  Experts in the field of marine environmental benchmark research in China are distributed in different institutions. In order to ensure the smooth progress of the marine environmental benchmark work in the 14th Five-Year Plan, we should give full play to the role of the National Environmental Benchmark Expert Committee as a think tank platform, and the superior research teams in the United Nations should work together to organize joint research. Through cooperation in a wider space and at a higher level, we will contribute wisdom and strength to the marine environmental benchmark work in China, better serve the marine ecological environmental protection in China, and meet the urgent need to speed up the modernization of the ecological civilization governance system and governance capacity.
 

During the 618 period, it increased by 86.5% year-on-year and became the most important player in the sinking market.

  It’s been a week since June 18, and when the June 18 war resumed, Juhua, which was fully restarted in March this year, became the biggest dark horse that suddenly emerged. The data shows that during the Tmall 618 period, the cost-effective year-on-year transaction growth reached 86.5%, and the year-on-year order growth was 106%.

  According to Alibaba, poly-cost-effective led to one-third of Tmall 618 transactions. According to the special report released by the authoritative Internet information service provider Analysys International on June 20th, Tmall’s market share during the promotion period was more than twice that of JD.COM and Pinduoduo combined, and one company accounted for nearly two-thirds of the total market share.

  The above picture shows the GMV comparison among different platforms very intuitively. The GMV of Taobao Tmall is 100, while that of JD.COM and Pinduoduo is 32.7 and 9.9 respectively. Poly-cost-effective leads to one-third of the transactions, which means that its index of leading transactions reaches 33, which is higher than that of JD.COM and Pinduoduo. More directly, a single gathering is cost-effective, and the turnover during Tmall 618 exceeded three Pinduoduo. In this year’s 618 War, the pattern of the sinking market has been rewritten. As an amoy department, Juhua rushed into the sinking market and gained a lot of advantages in the sinking market.

  On June 25th, Alibaba "officially announced" the overall growth of Tmall 618. Jiang Fan, president of Tmall, revealed at the launch conference of Tmall flagship store version 2.0 that the physical GMV of Tmall 618 increased by 38.5% year-on-year, and the DAU (daily active user) of mobile phone Taobao also increased by 29% year-on-year during Tmall 618.

  JD.COM did not disclose GMV figures, but the so-called "order amount". According to the figures published by JD.COM, the year-on-year growth of the order amount is only 26.5%, which is 12 percentage points lower than that of Tmall. As the largest e-commerce platform in the whole network, the growth rate of Tmall is also significantly ahead of competitors such as JD.COM. The ultra-high-speed growth of poly-cost-effective has further consolidated the dominant position of Amoy in the whole market.

  The cost-effective "revival" has also injected important traffic growth into mobile phone Taobao. The year-on-year growth rate of DAU of Hand Amoy is 29%, which is the highest since 2017. It also shows that it is cost-effective to tap the incremental population mainly based on the following heavy market users. Data from traffic monitoring third-party organizations such as Aurora Big Data and Questmobile all show that during the period of 618, the number of DAU (Daily Active Users) of mobile phone Taobao was in an absolute leading position, far exceeding other competitors.

  Win the sinking market

  A prominent feature of 618 this year is that "sinking market" has become a battleground for military strategists. In March this year, the comprehensive and cost-effective restart profoundly changed the war situation of 618 this year. Jiang Fan revealed a figure that 49% of Tmall 618′ s purchase users came from the 4 th, 5 th and 6 th tier cities.

  The research of Aurora Big Data shows that although the penetration rate of mobile phone Taobao in third-tier and below cities is slightly lower than that in first-and second-tier cities, it is still as high as 54.8%, which is significantly higher than that in Pinduoduo (39.5%) and JD.COM (22.3%). It is the only mainstream e-commerce software with a penetration rate of over 50% in third-tier and below cities. The DAU index of Taobao’s sinking market in the third line and below is more than twice that of Pinduoduo.

  In fact, before the start of Tmall 618, Alibaba began to deploy troops to strengthen the cost-effectiveness. Although Juhua was once an independent business unit of Amoy Department, it was merged into Tmall at the end of 2016. At the beginning of this year, Juhua became independent from Tmall and became a unified marketing platform for Taobao and Tmall, namely the marketing platform business unit. It is also known as Daju Cost-effective business unit.

  The new big gathering cost-effective covers the core marketing tools of Taobao, such as gathering cost-effective, rushing to buy, selling every day, etc. These business lines occupy almost half of the "half of the country" in the new edition of the hand-scouring six squares.

  Amoy is one of the most important goals of this year’s 618 strategy, which is to maximize the enthusiasm of users in the sinking market. Alibaba’s "618" this year is "the biggest investment in history" comparable to double 11’s, and the breakthrough has chosen to gather cost-effectiveness. The biggest game of "Ten Million Explosive Groups" is to maximize the marketing explosive power of the poly-cost-effective sale model.

  According to Alibaba, during Tmall 618, there were more than 180 million transactions and explosions, more than 4,700 million transactions and more than 4,200 items with sales exceeding 10,000 pieces, making it easy to achieve the small goal of "10 million explosion groups and 100 million explosion groups every day". The "Ten Million Explosive Groups" directly promoted the high growth of poly-cost-effective transaction volume. During the period of 618, the growth rate of poly-cost-effective transaction volume reached 89% year-on-year, and the number of users and purchases in third-and fifth-tier cities both increased by more than 100% year-on-year.

  Jiang Fan said at yesterday’s press conference: "The reason why Juhua can make such progress in just a few months is because it has returned to the original intention of ten years ago, that is, helping consumers find the best-priced goods in the whole network and helping businesses get customers with the most efficient marketing."

  The best tool for brand customers.

  Poly cost-effective comprehensive restart, and further become the brand’s best customer acquisition tool. Before Tmall 618, Juhua clearly put forward the goal of "bringing 300 million new customers to the brand", which was finally successfully achieved.

  This year, 128 brands of Tmall 618 were among the "Billion Club". More than 100 brands such as CPB, L ‘Oré al, Watsons, Dr. Chengye, Telunsu and Peak surpassed double 11 last year, and the sales performance of some brands reached 40 times that of double 11 last year. In this promotion, almost all the brands that became the "Billion Club" participated in the cost-effective activities.

  As the "biggest investment in history", 618 strives to convey "affordable" mind to consumers. The original price of Dyson hair dryer is nearly 3000 yuan, and 88VIP discount is added to the poly-cost-effective subsidy coupon, and the hand is as low as 1854 yuan. The brand with the original price of 1499 is bigger than an air conditioner, and it will be subsidized after the direct drop, and the hand price is 859 yuan. On June 18 th, Juhua launched the iPhone XR 618 yuan spike, which was less than 10% off the original price, causing the whole network to snap up. The investment of real money has undoubtedly greatly strengthened the influence of poly-cost-effectiveness on the consumer side.

  Tmall is the brand’s favorite new product release platform. During this year’s Tmall 618, 80% of the core brands released new products on Tmall. With Tmall’s powerful data and operational capabilities, brands can also aggregate consumer information, understand consumer preferences, conduct new product research and development, and create "explosive models".

  How to make "explosive models" sell better? Tmall has a set of marketing methodology. In Jia Luo’s view, the sale model is a means to help brands reach new customers as quickly as possible. In fact, there is also a very strong demand for branded goods in the sinking market. Brand goods with high cost performance can also "suck powder" quickly once they reach the sinking market. The long-term accumulated ability of Juhua has played a role in this respect. Before Juhua regained its independence from Tmall, it brought considerable business opportunities to the Tmall brand. In 2018, 80% of the brands that participated in Juhua came from new buyers, and the ability of Juhua to "pull new" can be seen. After the further restart, it was cost-effective, and the killer weapon of "Laxin" was used to the extreme. On June 25, the average growth rate of 400 brands participating in the launch of Tmall flagship store was as high as 47% during Tmall 618.

  Empowering industrial belt to create new supply

  The data shows that Handamoy has always been the largest shopping APP with the highest penetration rate in China, with more than 700 million consumers on this platform, with rich and diverse needs. How to meet their more and more diverse preferences, Amoy needs to work hard on the supply side.

  The breakthrough of Tao department selection is still a good deal. In addition to bringing new customers to traditional head brands, Juhua has set its sights on small and medium-sized businesses on the platform. Through their digital transformation, they can provide more high-quality and affordable products, which can meet the diverse needs of consumers and create more business growth for middle-aged businesses.

  Poly-cost-effective phase of the industry with businesses. In this year’s Tmall 618, a large number of small and medium-sized brands have entered people’s sight through Taobao, such as Yage electric mosquito swatter, Miaoyou children’s socks, Yi Enbei wet wipes, plant protection paper products, Fupai electric toothbrush, and Caramella socks. Although they don’t have the star aura of international brands, they are favored by consumers with high quality and low price. The reason behind it is also very simple. They have entered a cost-effective industrial belt support plan.

  As a big manufacturing country, China manufacturers have strong production capacity, forming various types of industrial belts such as digital accessories, electric toothbrushes, socks and paper towels. Many industrial belt manufacturers have long been OEM for well-known brands, but they lack their own brands. The daily sale of Juhua’s products fills the shortcomings of industrial belt merchants in operation, technology and brand ability, which can not only help them upgrade their products by digital means, but also solve the sales channels of their goods.

  On the other hand, when these industries bring merchants to the front desk, many categories of consumption upgrades have successfully reached the sinking market for the first time. For example, the electric toothbrush, a typical "consumption upgrade" commodity, was sold in the sinking market during Tmall 618. Fupai, an electric toothbrush brand in Taizhou, Zhejiang Province, sold 14,051 pieces in one minute after the opening of 618, and sold 400,000 pieces in 16 hours. Juhua cost-effectively pushed the industrial belt merchants and successfully awakened the upgrading needs of consumers in the sinking market. The industrial belt merchants also successfully won 466 million orders during the period of 618.

  Observing this year’s 618, the strong rise of poly-cost-effective is the most noteworthy phenomenon. To some extent, the battle of sinking market has been rewritten. Juhua Cost-effective, by its own efforts, has driven more transactions than the whole platform in JD.COM and Pinduoduo, which means that it has become the natural choice for users in the sinking market.

  For consumers, the "cost-effective" mentality has been established, and strong consumer insight and price competitiveness have greatly enhanced the user stickiness of the cost-effective platform. On the other hand, poly-cost-effectiveness has also become the integration of "Alibaba’s commercial operating system", which can effectively empower different types of businesses. The top brands can get more new customers through poly-cost-effectiveness, and the middle-waist businesses can also realize their own product evolution and brand upgrade through poly-cost-effectiveness.

  The key for Amoy Department to maintain its own competitiveness lies in creating new supply for consumers so as to meet their new demands. And poly-cost-effectiveness is the key link, and it has withstood the test in the 618 War.
