Small workshop production and online shopping with illegal additives have become new loopholes in food safety supervision.

  Buy imported milk powder and imported baby food supplements online, find someone online to buy pancakes and milk skins, and spend thousands of dollars to buy old wine &hellip, which originated in Taiwan, China; … These sales and purchases, which seem normal to many Internet "aborigines" at present, are actually dangerous behind them.

  On September 3rd, the reporter of China Youth Daily and China Youth Network learned from the White Paper on Trial of Food Safety Cases issued by Shanghai No.3 Intermediate People’s Court that online food safety disputes have now accounted for 64.4% of all civil cases involving food safety accepted by the hospital. Among them, more than 50% of the cases involved imported food, for example, the imported food sold by food business operators failed to pass the quarantine inspection by the national entry-exit inspection and quarantine department in accordance with the provisions of the Food Safety Law of People’s Republic of China (PRC). The phenomenon of selling imported food without inspection and quarantine in the name of "Daigou" is "more common".

  "Purchasing" milk powder does not go through customs? Ten times compensation can’t escape

  In one month, Xu bought a total of 4,680 yuan of Japanese milk powder in the Taobao shopping store opened by Shao for three times. No Chinese labels were found on the outer packaging of these milk powders. Xu later sued Shao for "one refund and ten compensation" on the grounds that the purchased goods "did not meet China’s food safety standards". The court of first instance ruled that Shao returned Xu’s purchase price of 4680 yuan and compensated 46800 yuan, and Xu returned the purchased milk powder. Shao refused to accept the appeal and appealed to Shanghai No.3 Intermediate People’s Court. The court of second instance dismissed the appeal and upheld the original judgment.

  Yao Jianzhong, president of the Civil Court of Shanghai No.3 Intermediate People’s Court, told the reporter that in the case of purchasing imported food tried by the court, most of the defendants had put forward the defense that "purchasing is not selling", but in most cases, these purchasing behaviors were recognized by the court as sales behaviors.

  The court found that the relationship between Shao and Xu was a sales contract, not a "purchasing relationship". Shao released milk powder information on the online platform, which clearly marked the goods as "spot" and all the orders involved were shipped from Zhejiang Province. Therefore, the court presumed that Shao had the "ownership" of the milk powder involved. Shao’s self-proclaimed purchasing behavior is actually a "spot buying and selling behavior". According to the Regulation on the Supervision and Administration of Quality and Safety of Dairy Products, dairy sellers have the obligation to check the incoming goods, verify suppliers and prohibit the purchase of unlabeled dairy products. In this case, the milk powder involved in the case sold by an online shop in Shao did not meet the above requirements.

  According to the Food Safety Law, imported food shall pass the inspection by the inspection and quarantine institutions, and the customs shall release it with the customs clearance certificate issued by the entry-exit inspection and quarantine institutions. Imported prepackaged foods shall have Chinese labels and instructions. The manufacturer and formula shall be registered and certified, the import shall be subject to strict inspection and quarantine, and the products sold shall meet the national milk powder quality standards.

  These milk powders sold by Shao entered the country by overseas mail, without customs inspection and quarantine. Japan, the place of production, is an unregistered access area. The outer packaging has neither Chinese labels nor instructions, nor relevant supporting documents that meet China’s national standards, and does not meet the provisions of the Food Safety Law.

  Jian Yao introduced that in real life, there are many such purchasing cases, which should attract the attention of consumers, purchasing agents and online shopping third-party platforms.

  Small workshop food and illegal additive food can still be sold.

  Zhang Moumou specializes in selling Xinjiang native products on Taobao. In two months’ time, he sold 42 copies of "Authentic apocynum tea of Xinjiang Specialty" to Wang Moumou, totaling 2068.85 yuan. But not long after, he was sued by Wang Moumou for violating the food safety law, and the other party asked him to "return one and lose ten". Both the first trial and the second trial supported Wang’s petition.

  The food safety law stipulates that the state implements a licensing system for food production and operation, and food safety standards should include requirements for labels, signs and instructions related to food safety requirements such as hygiene and nutrition, that is, food production and sales should be licensed in advance according to law, and the license should be marked on the pre-packaging of food.

  In this case, the "apocynum tea" sold in Zhang Moumou has no food business license or other signs, and belongs to unlicensed food. Zhang Moumou proposed in the second trial that the apocynum tea belongs to health food. The "apocynum tea" he sells has neither the approval number of health care products nor the logo of food business license, which violates the provisions of the Food Safety Law.

  The court held that Zhang Moumou, as an operator, failed to fulfill the obligation of incoming goods inspection and sold unlicensed food, which belonged to the act of selling food knowing that it did not meet the food safety standards, thus supporting the consumer’s petition.

  In another case, consumer Jiang spent 5,600 yuan to buy two bottles of "Golden Gate Sorghum Gold Foil Wine (Limited Issue)" from Taiwan, China in a Taobao shop opened by a liquor company in Tangshan. But when he gave the wine to his friend, he was told by his friend that gold foil was not a food additive and was not allowed to be added to food. The Ministry of Health clearly stipulates that gold foil shall not be used as food raw materials and food additives, and it is forbidden to add gold foil to food. The plaintiff demanded "one refund and ten compensation".

  Shanghai No.3 Intermediate People’s Court believes that the law stipulates that "food" refers to all kinds of finished products and raw materials for human consumption or drinking, as well as articles that are traditionally both food and Chinese herbal medicines, but does not include articles for therapeutic purposes. The commodity involved in this case is liquor, not food. However, gold foil is neither a raw material for alcoholic food production, nor can it be eaten as a food additive, so it is an illegal additive. The court upheld the plaintiff’s claim.

  Yao Jianzhong told the reporter that in the actual judgment process of Shanghai No.3 Intermediate People’s Court, in addition to many cases where the actual theme of online shopping is inconsistent with the online registration entity, the sale of homemade food without a food business license, and the sale of food that has been identified as unqualified, "many cases still appear on the Internet after media reports and penalties imposed by relevant departments."

  The supervision of third-party online shopping platforms is lax, and administrative supervision is still lacking.

  China’s food safety law stipulates that if the provider of the third-party platform for online food trading fails to register the real name of the online food business operator, examine the license, or fails to perform the obligations such as reporting and stopping providing online trading platform services, in addition to bearing the corresponding administrative responsibilities, the legitimate rights and interests of consumers are damaged, and they shall be jointly and severally liable with the food business operator.

  According to the data held by Shanghai No.3 Intermediate People’s Court, the number of food safety cases currently occurring in online shopping channels is much larger than that in the field of physical transactions, and there have been problems such as food that has been identified as not meeting food safety standards still being sold publicly, selling homemade food without food production and operation license, and illegally selling health food, which "reflects the prominent problems existing in the food sales field of third-party online shopping platforms, and also reflects the shortcomings of third-party online shopping platforms in implementing regulatory responsibilities and fulfilling regulatory obligations".

  The trial of the case also reflected that there are still weak links in the supervision of food sales on the online shopping platform by the administrative supervision department. In related cases, the number of subjects who produce and sell foods that do not meet food safety standards is relatively small. Objectively speaking, Internet transactions do bring difficulties to administrative supervision because of their large transaction volume, rapid commodity circulation and wide circulation range.

  The court suggested that relevant departments establish a national unified credit file for food production and operation enterprises, and establish a food safety information platform based on big data analysis to improve the effectiveness of food safety supervision.

Say goodbye to the gas tiger 2013 Buick Excelle car purchase manual

  [Pacific Auto Network Shopping Guide Channel]As one of the representatives of the new three kinds, it has been listed for ten years, but with the low price, the quality of leather and the great advantages of Buick brand, the sales of Excelle are still staggering. However, although the leather Excelle sells well, it is not without its shortcomings. Among them, the most common headache for consumers is the conventional fuel consumption of American cars. However, on February 1st, 2013, the new Excelle will be equipped with a brand-new 1.5L, and the transmission part will be upgraded from the original 4AT to 6AT. The optimization of powertrain will bring better fuel economy, so that the previous gas tiger hat is finally completely lost.

        Recently, Buick Excelle has a certain discount. You canclick hereAfter submitting the information, some staff will contact you. For more preferential information, you canclick hereMake an inquiry.

  Since the upgrade of the new Excelle is a small change at best, it doesn’t make much sense to introduce this familiar car too much. The following small series will explain the key projects of this upgrade.

● Highlight 1: Power/fuel consumption: 1.5L engine replaces 1.6L engine, 4AT is upgraded to 6AT, and fuel consumption is reduced.

  The biggest highlight of the new Excelle is naturally the upgrade of this powertrain. The 1.6L engine that had been supported for many years before was replaced by Buick’s brand-new 1.5L DVVT inline four-cylinder engine. Although it dropped slightly, the output of 83kW(113PS)/6000rpm was slightly higher than that of the current 1.6L model. On the other hand, this 1.5L engine can reach a peak torque of 140Nm at 4000rpm. Matching this brand-new engine is a brand-new 6-speed automatic manual transmission and the existing 5-speed.

  At the same time of power upgrade, the new car also has better fuel economy. According to the published data, the comprehensive fuel consumption of the new Excelle 1.5L DVVT manual transmission model is 6.6L/100km, and that of the automatic transmission model is 7.6L/100km, which is 1.1 liters and 0.4 liters lower than that of the old 1.6L manual and automatic transmission models, respectively.

● Highlight 2: The fine-tuning of appearance changes has become more atmospheric.

  The appearance design of the new Excelle has changed a little, and the most obvious thing in the front face is that the lower air inlet has been changed from the original separated type to the integrated type connected with the fog lamp. Secondly, the structure of the internal lamp group of the headlight has been adjusted, and the crystal diamond ice blue of the new projection headlight is eye-catching. In addition, the new turn signal returned to the fender from the original rearview mirror.

  There is basically no change in the rear of the car, and the full LED brake lights used before the taillights are replaced by ordinary halogen bulbs. On the models with different configurations, the biggest difference between the high-profile models and the low-profile models is the four probes on the rear bumper.

● Summary of vehicle highlights:Generally speaking, this time, the upgrade of the new Excelle is a medium-term small change, mainly aimed at improving the high fuel consumption problem that consumers have reported very commonly, but there is not much change in other aspects.

Really unchanged for 50 years? Review of Porsche 911 Development History

  [History of car home Car Series] There is a car, which has been unchanged for more than 50 years and has a pair of big eyes that are harmless to people and animals, which makes every car fan dream. From the origin to the present, everything has been put together by mistake, and it has become a world classic because of such a mistake. This car, yes, is a Porsche 911.

Introduction of the Old-timers-Porsche 356 Series (1948-1965)

  If we want to talk about how Porsche 911 has become like this step by step, we should start with its predecessor, Porsche 356. Porsche 356 series is Porsche’s first mass-produced sports car with its own brand, which was born out of Beetle technology and focused on optimizing the lightweight, aerodynamics and handling of the car body. All these laid the foundation for the design features of the Porsche 911 in the future, and passed it on to this day, making it unique.

Home of the car

  In 1931, in Stuttgart, Germany, Dr. ferdinand porsche founded his own design company. The brilliant road of a generation of mechanical design masters has since reached its peak. Before World War II, ferdinand porsche was entrusted by Hitler to participate in the national car program, and in 1937, he "designed" the Volkswagen Beetle (then called K?fer). Although nominally designed independently, it is rumored that this car has made a lot of reference to the Tatra V570 model designed by Hans Ledwinka and Tatra in 1930. Indeed, it is really impossible to build such a classic model from scratch in a short time.

Home of the car

  So such a "reference work" makes Porsche get attention instead of Hans Ledwinka. Why? In fact, Hitler didn’t know that this work had reference elements, but due to his close personal relationship with Porsche (this can be seen from the fact that the tank designed by Porsche failed in bidding, and the tank that was successfully tendered was forcibly assembled with Porsche chassis), Hitler said "turning a blind eye" to this matter.

Home of the car

  Then why didn’t Hans Ledwinka pursue this matter in depth? First of all, they did fight a lawsuit for a long time. In 1965, Volkswagen personally compensated Hans Ledwinka for 3 million marks (equivalent to the income of Porsche for about 3 months). Secondly, Hans Ledwinka became a war criminal after World War II, and it was the Porsche family that spared no effort to bail him out. Finally, ferdinand porsche once admitted in his personal letter that his success was on Hans Ledwinka’s shoulders.

  Type 64 is specially built for Berlin-Rome rally, based on Volkswagen Beetle, horizontally opposed engine, rear-mounted rear-drive design, aluminum body, fully considering wind resistance and lightweight. And this car has also become the origin of Porsche’s sports car in the future. Although this car has not been mass-produced, for Porsche, this car has laid a good foundation for Porsche’s determination to make a sports car in the future and laid a good conceptual foundation for Porsche to realize its dream of a sports car.

Home of the car

  After the war, Germany was in a mess, and ferdinand porsche was jailed for participating in the design of various military products, and was released in 1947. Of course, this fanatical technical fan will not stop his obsession with vehicle development and performance because he regained his freedom. On the contrary, ferdinand Porsche hoped to make a sports car of his own brand. This wish was supported by his son Ferry Porsche, and Porsche had the technology of the Beatles at that time, so with the support of his children, he quickly launched a new car plan-the Porsche 356 sports car with Porsche brand instead of Volkswagen brand was released in 1948.

Home of the car

  Porsche 356 sports car can be simply understood as a "sports car model" of Volkswagen Beetle in its early days, and more than 40% of its parts are common with Beetle. In fact, from a technical point of view, relying on Beetle technology is more out of helplessness, because Porsche after the war only has some drawings of Volkswagen Beetle, and if it wants to realize production quickly, it is necessary to adopt some ready-made things. Therefore, it is not difficult to understand that in the development process of Porsche 356, relying on Beetle technology, and it is for this reason that Porsche has achieved great success.

Home of the car

  The unique structure and shape, combined with the handling brought by the short body, make the Porsche 356 distinctive among many sports cars. Although there is no high power reserve, the light body and low wind resistance design have indeed made a lot of contributions to the market. Think about the current car companies want to develop a car. Lightweight and low wind resistance are definitely the focus of research and development. As early as the late 1940s, Porsche already had mass-produced models under this concept. From this point, it can be seen that Porsche is really far-sighted.

Home of the car

  The increasingly complex line design makes Porsche 356 gradually get rid of its original simple appearance. The wider track and tires make it look more or less like a sports car. However, even if it is upgraded, it is still the cute look of the Beatles and the rear drive structure that is being passed down.

Home of the car

  This rear-mounted rear-drive structure+simple and lightweight sports car brought Porsche the first bucket of gold, and the success of this sports car brought a group of loyal customers and fans, which made Porsche have an idea: the future generation of sports cars will still adopt this design concept. This is also the origin of why Porsche 911 is loyal to the rear drive structure.

A new beginning-the first generation Porsche 911(1964-1973)

  The 356 model, which was born out of Beetle technology, has been exhausted after 17 years of production and can’t keep up with the progress of the times. Porsche urgently needs a new car to inherit the mission of the 356 model, and at the same time of innovation, it must inherit the classics, be unique, be full of power and be the best in its class. Based on this idea, the famous Porsche 911 (hereinafter referred to as 911) was born.

Home of the car

  In fact, in the design process, Porsche once thought about giving up the structure of rear-mounted rear drive and switching to the structure of center-mounted rear drive or front-mounted rear drive, which has a relatively balanced front and rear axle load, so that the vehicle has a relatively stable handling characteristic. However, due to the persistence of fans and people’s subconscious concept that "only rear-mounted rear-drive is the most authentic Porsche sports car", Porsche 911 finally adopted this rear-mounted rear-drive structure and adopted the front McPherson rear torsion beam suspension. As for the middle rear-drive and front rear-drive sports cars? Leave it to other series.

Home of the car

  Porsche 901 model generally inherits the classic design of "Flat Beetle" in appearance, but it has no technical intersection with Beetle. Everything is brand-new and its appearance is more modern. The engine has been upgraded from horizontally opposed 4 cylinders to horizontally opposed 6 cylinders, with more power, larger body and greatly improved comfort.

Home of the car

  Because Peugeot registered the copyright of all three-digit combinations with 0 in the middle (such as Peugeot 307 and Peugeot 508, which we are now familiar with), due to the dissatisfaction of Peugeot, only 82 models named 901 were manufactured and then renamed Porsche 911. As for why the number 911 is used, there is actually no special reason-simply changing 0 to 1.

Home of the car

  However, this does not mean that the number 901 has come to an end. Because in the research and development stage, the first-generation 911 has always been named by 901, Porsche simply represents the first-generation model of 911 with the code name 901, so the first-generation 911 is often called 901.

Home of the car

  Although from the perspective of inheritance, 911 is the replacement model of 356 in terms of structure and concept, from the technical point of view, 356 has no direct technical inheritance model because it completely surpasses 356 (the price is the same). For this reason, Porsche replaced the 911 with a 1.6-liter horizontally opposed 4-cylinder engine (output 90Ps) on the 356C, and renamed the car 912 to fill the gap in the 356 market. There was only one generation of the 912 model, and then the 912 was replaced by the 914 with the middle rear drive structure.

Home of the car

  With sufficient capital, it is impossible for Porsche to sell only one model of 911 in the market. In addition, with the increasingly diversified needs of users, Porsche began to segment the market for its 911 models. From the initial only 2.0 horizontally opposed 6-cylinder engine of Type 901/01 (the output power is 130Ps, equipped with a 5-speed manual dense-tooth gearbox, and the maximum speed is 210km/h), to the different power levels adjusted by various later versions, 911 has accurately positioned different customer groups.

Home of the car

  In terms of interior, some elements of Porsche 356 can be seen in the first generation Porsche 911: green dashboard and a large number of chrome-plated decorative pieces. However, the five-link meter and the key jack on the outer side have been formed, and the instrument panel with the upper part protruding inward will become the classic interior elements of Porsche 911 in the future.

Home of the car

  The newly changed 5-spoke Fuchs wheel has become one of the classic elements of the old 911 because of the success of the Porsche 911 in the future. Even in many nostalgic 911 models, we can still see this wheel style (such as the Speedster model of the sixth generation 911).

Home of the car

  As for the power system, the horizontally opposed 6-cylinder engine with higher output replaced the original engine, which made the power performance of Porsche 911 go up to a higher level: the 911S was equipped with a Type 901/02 engine, and the output power increased by 30Ps to 160Ps, which brought better power performance to the 911S.

  Because the American High-speed Safety Committee stipulated that there was a risk of head injury when the fully convertible structure was overturned, Porsche 911 Targa installed a T-beam similar to the roll cage to reduce the hidden danger of head injury during the rollover. This design earned the 911 Targa the title of "the safest convertible in North America", and this design became the classic styling feature of the Porsche 911 Targa model, which was in short supply after listing. This "T-shaped roof" designed for legal compromise later became a classic design form of 911 convertible, which has both aesthetic feeling and safety. The Targa model has been accompanied by the 911 to this day, which has created the sales miracle of the 911 model in the convertible market.

  Speaking of the change of Porsche 911, if you are not a fan of Porsche 911, you should not be able to see where it has been changed. Indeed, every time 911 changes the money, it gives consumers the feeling that they are playing "Let’s find fault". Although the appearance has not changed much, every change is perfect for this "car that has been changed for more than 50 years" in terms of details and machinery.

Home of the car

  In the early days, 911+ letters were used to represent vehicles with different power levels: 911T stands for 110Ps output version, which was released in 1968 to fill the market gap between 911 and 912; 911L stands for 130Ps output version; 911S stands for the 160Ps output version, that is, the high-power version, and all of them can be equipped with the Sportmatic semi-automatic gearbox. Even the most basic version of the 911T, Porsche can still win the Monte Carlo Rally twice with its excellent performance.

Home of the car

  In the first generation of 911 models, every small change in appearance is minimal, but in terms of details, these seemingly minor improvements are an improvement for the 911 car series.

Home of the car

  This change, code-named 911C, can be regarded as a relatively big change in the first generation model: the biggest change in this adjustment is the engine, which is upgraded from 2.0 displacement to 2.2 displacement, and the corresponding engine power is also improved. In order to cope with the problem of too sensitive handling under extreme conditions, the wheelbase is increased from 2211mm to 2268 mm.

Home of the car

  After the redesign, the interior of the 911 has basically maintained its original appearance, and the five-link meter and the outer key jack are still the same. However, the color scheme of the instrument is no longer green, but close to the color scheme of some current models with red needles on white background. The application degree of plastic parts has increased to a certain extent compared with that before the redesign, and the steering wheel style has also changed.

Home of the car

  In the subsequent modifications, including three adjustments with codes 911D, E and F, the displacement was increased from 2.2 to 2.4, and Bosch mechanical injection technology (MFI) was used to achieve better fuel injection effect. In addition, there were some changes in small details such as the change of fuel filler, but the classic appearance and structural layout remained unchanged.

Home of the car

  The 911 Carrera 2.7 RS, which was launched in 1973, can be regarded as the first time that Porsche launched such a mass-produced model with emphasis on competitive sports in the civilian market, and it was also the largest displacement model among the mass-produced 911 cars at that time, with a maximum speed of 245 km/h. The word Carrera originated from the race of Carrera Panamericana in Mexico. In order to commemorate the victory of Porsche in this race, the word Carrera was first used on the 356 Carrera model, symbolizing Porsche’s honor in motorsport. The classic duck tail and the newly designed front bumper became the iconic design of this car, and from this, the Porsche 911 RS series, which pays attention to competitive needs, was born.

  The birth of the first generation of 911 can be regarded as a comprehensive transcendence of 356 in terms of various indicators, with larger and more comfortable handling, but accurate and extremely interesting, which contributed to the success of Porsche 911, and the development of RS models pushed the 911 car series to the direction of high performance and competitive demand.

The birth of a new model-the second generation Porsche 911(1973-1989)

  From the code point of view, many people are used to calling the second-generation 911 930, but from the official and technical point of view, the second-generation 911 has a great intersection with the first-generation 911, so what should this generation 911 be called? Can this generation continue to inherit the classics and carry them forward?

Home of the car

  The second-generation 911 model, the accurate code name can only be said to be the 911G series model. In order to meet the strict requirements of American laws for bumpers, this generation of 911 has installed front and rear bumpers with low-speed protection and collapse function, which has better safety performance, and also gives this generation of 911 a certain degree of modernization characteristics, and the bumper with outstanding style has also become the characteristic design of this generation of 911. The overall replacement of the 2.7-liter horizontally opposed six-cylinder engine (150Ps for the 911 and 175Ps for the 911S) has finally made this generation of 911 no longer lag behind in terms of power.

Home of the car

  In terms of interior, this generation of 911 has moved up the air conditioning outlet, changed the steering wheel style, made some adjustments in the inner door panel, added more leather materials, and improved the comfort configuration to a certain extent.

Home of the car

  At this point, the standard version of the 911 was renamed as 911 Carrera, which made the name Carrera exist in the 911 car series for a long time. And in the process of later modification, the engine with higher displacement was gradually equipped. In 1976, it was upgraded to a 3.0 horizontally opposed 6-cylinder engine, which can be matched with a 4-speed, 5-speed manual gearbox and a 3-speed Sportmatic semi-automatic gearbox. The acceleration time of 100 kilometers is only 6.1s, and the maximum speed is 236 km/h.

  In this generation of 911, Porsche 911 Carrera Turbo 3.0, the first production version equipped with turbocharged engine in Porsche history, has its own independent code name, namely 930. The appearance of this car made Porsche 911 the first sports car with turbocharged engine.

Home of the car

  The 911 Carrera Turbo 3.0, which adopted turbocharging technology, had excellent output book data (matching with a 4-speed manual gearbox, the measured acceleration per 100 kilometers was only 5.2s, and the maximum speed was 250km/h) compared with competitors of the same level at that time, which opened a big gap in performance. In order to control this engine with strong output, Porsche has equipped it with a wider wheel arch to match the wider tire and track and ensure the grip. This "fat ass" design, combined with the new duck tail, will become a body form in the 911 car series in the future, and it will not only be matched in the Turbo model, but also be matched in some performance models from time to time.

Home of the car

  Based on the 911 Turbo model, Porsche has also developed a lot of racing cars specially for racing, which makes the 911 Turbo model not only famous in the sports car industry, but also swept the champions in various races. It is absolutely eye-catching to know that a 911 can perform as well as those racing cars (such as Ferrari, Lamborghini, etc.) transformed from super-running. The 934 Turbo RSR racing car pictured above has also been rumored to be the source of inspiration for RWB. As for the truth, different people have different opinions, and the eye-catching widened wheel eyebrows are really eye-catching.

  While everyone is still amazed at the powerful output of this 3.0T horizontally opposed six-cylinder turbocharged engine, only two years later, the Porsche 911 Turbo model with a 3.3T horizontally opposed six-cylinder turbocharged engine replaced the 3.0T version, and its power performance was even more amazing (up to 300Ps and matched with a 5-speed manual gearbox, the measured acceleration per 100 kilometers was 5s, and the maximum speed was 260km/h). In addition, the 911 Turbo model was named after Carrera, and it became a relatively independent positioning model different from Carrera model, and it was replaced with a new tail form. In the instrument panel part of the interior, a turbocharger meter is added to the tachometer.

  In addition to the general version of the 911 Turbo model, the 911 Turbo also appeared a flip version model named Flachbau Coupe in the same period, realizing more diversified choices. The success of the 911 Turbo made the second generation Porsche famous, and this generation of Porsche 911 Turbo did not officially stop production until 1989, and reluctantly bid farewell to the historical stage.

  It is not accurate enough to say that 911SC is a brand-new model: 911SC first appeared in 1978, and SC stands for Super Carrera, which is the renamed successor model of 911 Carrera. The car adopts Bosch K-Jetronic fuel injection system, which has a power output performance of more than 180Ps (later upgraded to more than 204Ps).

  And if the Cabriolet model is said, it really appeared for the first time in the history of 911. This orthodox 911 series convertible first appeared in 1982, and it is also the first convertible of 911 after 356 Cabriolet for many years. The difference between the 911 Cabriolet and the 911 Targa is that this car does not have a B-pillar design similar to the roll cage, and it is a standard convertible structure.

  This generation of Porsche 911 also participated in the Paris-Dakar Rally in 1984 (the 911 Carrera 4X4 car above), which not only finished the whole race, but also made Porsche win the championship for the first time. Not only that, in the following two years, Porsche won the 1985 Pharaoh Rally and the 1986 Dakar Rally with the 959 car. A sports car snatched a cross-country rally champion from many off-road vehicles, which is unique in the history of automobiles.

  The Porsche 911 pictured above is the last work of the second generation 911. The Speedster model is not only a tribute to the 356 Speedster, but also a more inclined small windshield design and two-seat structure, which are different from other 911 features. When it comes to the origin of Speedster, it was originally designed for the pursuit of low wind resistance. The extreme Speedster is a closed body design with no windshield and only the driver’s seat.

  At this point, we have briefly introduced the second generation Porsche 911 model. The second-generation Porsche 911 has made many initiatives in vehicle innovation: the first-generation 911 Turbo model (930) developed on the basis of the second-generation 911 has made a great breakthrough in the performance of the 911, and the 911 Cabriolet convertible has also appeared for the first time in the 911 car series. Do you understand the relationship between the second generation 911 and 930?

The Third Generation Porsche 911(1989-1994) Stepping into the Era of Science and Technology

  The birth of the third-generation Porsche 911 marks that Porsche has entered a new era, changed its old-fashioned image and took the first step in the technological transformation of the 911 car image. Compared with the previous two generations, this generation of 911 models has a shorter production year, but the sales volume is not low, which also makes Porsche 911 successfully upgrade in the field of water testing technology and finally become a modern sports car.

  Since the release of the third generation model, the intention of Porsche 911 to modernize can be seen in many aspects: the initial release model is 911 Carrera 4, a 4-wheel drive 911 model, which is unprecedented in the history of 911, and now the naming rules of 911 cars applied by Porsche Company are unified from this generation model.

  In terms of technical upgrading, this generation of vehicles has done a good job: such as power steering, ABS system, Tiptronic automatic transmission (1990) and standard double airbags (1991) all appeared in Porsche 911 for the first time. When the speed is higher than 80km/h, the rear air inlet can be automatically raised by the motor to ensure better engine cooling effect and air intake efficiency. Not only in the field of science and technology, but also in terms of power, the newly upgraded 3.6 horizontally opposed 6-cylinder engine has brought 250Ps basic output power to this generation of Porsche 911 (with an acceleration of 5.9s per 100 kilometers and a maximum speed of 260km/h).

  The design of the whole car is no longer decorated with a large number of chrome-plated parts, which makes the whole car look less "bling". The rounded shape makes the drag coefficient lower (Cd=0.32), the wider body and wheel track, and the bumper design with stronger overall feeling make this generation of Porsche 911 look no longer like an old car, and finally have some modern design sense.

  Like the previous generation of 911 Turbo, this generation of 911 Turbo (code 965) adopts a wider track and body than the standard version, and this wide body form will also be used in the 3.8-displacement RS model. At the beginning, the new 911 Turbo still used a 3.3T turbocharged engine, but now it can release 320Ps. Two years later, the turbocharged engine based on the 3.6 engine was assembled on the car and could release 360Ps.

  The retention of the 911 Targa model can actually show Porsche’s persistence in this classic convertible shape. Like the previous generation, this generation of 911 Targa can be equipped with a rear windshield made of a whole curved glass. But this kind of persistence only lasts until this generation, and there is no following. What is the next generation of Targa? It will be mentioned in the 911 model introduction on the next page.

  Like the first generation of RS, this generation of RS, which was born in 1991, introduced a lightweight rear-wheel drive model to meet the competitive demand. The newly changed lightweight rim has become a classic rim modeling reference style for Porsche 911 models. This car is not only the basis of the Porsche Cup car, but also a tribute to the 911 Carrera RS 2.7 and 3.0 RSR models.

Home of the car

  However, because the 3.6-liter RS model has no obvious change compared with the standard version, the low-key appearance really makes buyers uninterested. Porsche decided to strengthen it again and developed the 911 Carrera RS 3.8 model. As you can see from the name, the displacement of this car has increased to 3.8 liters, the output power has reached 300Ps, and it has been transformed into a more competitive one: it has been replaced with a Turbo wide wheel brow body, wide tires and a more exaggerated tail. With the new competitive vibration reduction, the fighting capacity on the ground is fully demonstrated, and the performance on the field is also the same. This transformation is worthy of the name of RS.

Home of the car

  The progress of the third-generation Porsche 911 has finally brought Porsche into line with this technology-led world. This generation of 911 initiated the first step in the history of Porsche 911′ s transformation to electronization and technology, and from then on, Porsche 911 is no longer an outdated machine that is tiring to drive, but has really become a sports car that can take care of daily use. Of course, while making progress, the classic rear drive structure remains unchanged.

The King of Air Cooling —— The Fourth Generation Porsche 911(1993-1998)

  The fourth generation of 911 appeared in 1993. This generation of 911 can be regarded as a generation with great changes in appearance: the headlight design with larger inclination angle and the use of more rounded lines make it very popular in current design, and the rounded body shape and optimized body proportion make this generation of 911 the "most beautiful air-cooled 911". Of course, the most important thing is that the power and handling of this generation of 911 are outstanding.

Home of the car

  The successful innovation of styling and the overall improvement of power level have made this generation of 911 get the evaluation of "the perfect combination of art and machinery", and this generation of 911 has also become the last generation of air-cooled engine 911 in its history. Together, these factors make this generation of Porsche 911 extremely valuable in the eyes of collectors and fans.

Home of the car

  With the development of the times, there is still no obvious change in the interior of this generation of Porsche, but the configuration function has become much more than before, such as the optional damping adjustment suspension, which has reserved places. In addition, this generation is also the first generation of CD players.

Home of the car

  Although the displacement has not changed, this engine is brand-new, and the engine management computer (ECU) and exhaust design are optimized, and it can output 272 ps (VarioCam system was equipped in 1996, and the output power was upgraded to 286Ps, but it was followed by a high failure rate, which made many Porsche collectors more willing to buy a car before 1996), which is a great progress for a standard 911. In addition, the optimization of transmission efficiency and structural design, the application of new suspension (the rear suspension adopts multi-link structure for the first time), and the rigidity is 20% higher than that of the previous paragraph, all of which make this generation of 911 Carrera an integrated body with both aesthetic feeling and speed, and lay a good foundation for the launch of high-performance versions in the future.

Home of the car

  In addition to the standard version of 911 Carrera, Carrera 4, Cabriolet and Targa with four-wheel drive system are also in the product line, but in this generation of 911 Targa, which was born in 1995, what we saw was no longer the classic "T-beam" design, but an openable panoramic skylight. Although this design is very futuristic and conforms to the trend of the times, this practice against the classics will inevitably disappoint many fans.

Home of the car

  Although Targa’s new design did not achieve the expected results, it did not affect people’s enthusiasm for buying: since Targa’s classic design is gone, let’s switch to Cabriolet. Indeed, this innovative design has finally made the Cabriolet model, which was born a year earlier, a legitimate 911 convertible.

Home of the car

  In 1995, the fourth-generation 911 Turbo was born, relying on the new 3.6-liter horizontally opposed 6-cylinder engine. By adding dual turbochargers, the data can be described as the peak: the terrible output of 400Ps and 541N·m was achieved, and the production version of 911 Turbo entered the "400-horse club" for the first time. This is not over yet. There is a higher-level version of the 911 Turbo S model in the subsequent Turbo models, and the data is as high as 424Ps. This generation is also the first 911 Turbo model equipped with a four-wheel drive system and a 6-speed manual transmission.

Home of the car

  The powerful output depends on the powerful cooling mechanism. From the first generation of 911 Turbo, the larger and larger intercooler can be seen that in its evolutionary history, the appetite of 911 Turbo is getting bigger and bigger. Even in the 911 Turbo S model, two holes are opened on the rear wheel eyebrow to meet the higher cooling demand (911 Turbo S is only sold in North America), and this design has become a symbol in the future 911 Turbo models.

Home of the car

  Compared with the standard model 911 Carrera without S, these two cars use the wide wheel arch body of Turbo (but have no tail) in appearance, and are equipped with new rims, larger brake discs, red calipers and sports vibration reduction, which have better sports effect and lighter weight. This car can be seen as an alternative to the previous generation 911 Carrera RS 3.6.

Home of the car

  This generation of 911 Carrera RS has also made great efforts in weight reduction: aluminum rims and rear seat removal have made it lose a lot of weight (120kg), achieving an acceleration of 4.9s per 100 kilometers and a maximum speed of 277km/h, and a limited edition of the competitive 911 Carrera RS Clubsport version (that is, the version that replaces the old RSR model) has been launched in the future.

  After talking about the lightweight RS version and the high-output Turbo version, this generation also produced a quasi-road racing car named 911 GT2 from 1995 to 1997. The early 911 GT2 was just a car based on the 911 Turbo, which was in line with the GT2 race group. Because of the eye-catching results, fans are very vocal about this, and Porsche decided to transform this car into a highway and go public.

Home of the car

  The road version of the 911 GT2 is not so much an evolutionary version of the 911 Turbo as a racing car that can go on the road. The twin-turbocharged engine squeezes out 430Ps (later version 450Ps) and 586N·m, and all of them are output to the rear axle. Coupled with the highly lightweight treatment and the rivet width with racing style, the maximum speed of 4.4s and 295km/h per 100 kilometers is achieved. It was definitely the king of 911 in that year, and it was also the favorite of many fans and collectors. It was hard to find a car.

  After talking about the official history, let’s look at some "eggs", which are rare to see Porsche 911:

  In [History of car home Cars], we reviewed the history of the first four generations of Porsche 911 with you. Their common feature is that the power system is equipped with air-cooled engines. In this article, we will continue to introduce the history of Porsche 911 with water-cooled engine from the fifth generation to the latest generation.

Opening the era of water cooling-the fifth generation Porsche 911(1997-2005)

Porsche Porsche 911 2004 Carrera Coupe MT 3.6L

  As early as 1993 ~ 1994, the fifth-generation Porsche 911 with internal code 996 had already started research and development. Unlike the previous four generations of 911 from the same platform, the fifth generation of 911 was born from a brand new platform. In September, 1997, Porsche officially released the fifth generation 911. The new car was designed by Lai Ping, a Chinese Porsche designer. The smooth body lines and the more inclined windshield made it have a low drag coefficient of 0.3.

Porsche Porsche 911 2004 Carrera Coupe MT 3.6L

  Compared with the previous model, the body size of the fifth-generation 911 has increased by one circle, and the wheelbase has also been extended by 78mm, reaching 2350mm, thus obtaining more spacious interior space. Nevertheless, the subversive changes of the fifth-generation Porsche 911 have made it difficult for fans to accept for a long time. Among them, the most criticized is the front face design. The iconic frog-eye round lamp of 911 was replaced by the "fried egg" headlights from Boxster (code 986), a Porsche entry-level model at that time, which made many 911 car owners feel that their cars were lowered.

Porsche Porsche 911 2004 Carrera Coupe MT 3.6L

  In the interior part, the fifth-generation 911 also adopts the same style and layout as the first-generation Boxster introduced earlier. The difference is that the 911 retains the classic dashboard composed of five small dials, but the relative positions between the small dials are more compact. At the same time, the steering wheel is still in the traditional four-spoke shape, and the air outlet and buttons on the central control panel are not as flamboyant and fashionable as those on the Boxster, but appear relatively low-key and calm.

  Compared with the brand-new design of appearance and interior, the most significant change of the fifth-generation model is to completely stop using the air-cooled engine of 911 series for 34 years and switch to water-cooled engine. The main reason why Porsche gave up air cooling is that the 911 series has to deal with stricter emission and noise regulations, and Porsche also hopes to further improve the efficiency of the engine.

Porsche Porsche 911 2004 Carrera Coupe MT 3.6L

  Porsche first introduced the entry-level model 911 Carrera, whose body structure is a 2-door 2+2-seat hardtop sports car, and its driving mode is rear-mounted and rear-driven. The power system of 911 Carrera is equipped with a brand-new 3.4L horizontally opposed water-cooled engine, with a maximum power of 300 HP and a peak torque of 350 Nm. The transmission system is matched with a 6-speed manual gearbox (optional Mercedes-Benz 5G-Tronic automatic gearbox), the acceleration time of 0-100km/h is 5.2 seconds, and the maximum speed is 280 km/h..

  At the same time, the 911 Carrera Cabriolet with soft-top convertible design and rear-wheel drive was introduced, and then Porsche added a four-wheel drive version to the 911 series. In terms of chassis, the fifth-generation 911 adopts the former McPherson independent suspension shared with Boxster, and the latter multi-link independent suspension is derived from the previous generation 911 (code 993). In addition, it is worth mentioning that the fifth-generation 911 is also equipped with Porsche Stability Management System (PSM) for the first time, which is an electronic control system that can ensure vehicle stability and improve driving safety.

  In September, 1999, Porsche released the 911 Turbo with four-wheel drive system as standard. The car adopted a brand-new aerodynamic kit, with sharper headlight group and bi-xenon headlights. When the vehicle speed exceeds 122km/h, the auxiliary spoiler on the fixed rear spoiler will automatically rise. The power system of 911 Turbo is equipped with a 3.6L horizontally opposed twin-turbo engine, which is derived from Porsche 911 GT1-98, the champion of the 24 Hours of Le Mans in 1998. It adopts variable valve timing/lift technology, with a maximum power of 420 HP and a peak torque of 563 Nm.

  In 2000, Porsche launched the 911 Carrera Millennium Edition to celebrate the arrival of the Millennium. The car has special purple metallic paint, brown leather interior and maple wood ornaments, and it is limited to 911 sets. In 2001, Porsche introduced a more powerful 911 GT2, which uses rear-wheel drive, the aerodynamic package of the car body is more exaggerated than that of the 911 Turbo, ceramic brake discs are also standard, and the rear seats and air conditioning system are removed from the car. The power system of the 911 GT2 is equipped with a re-adjusted 3.6L horizontally opposed twin-turbo engine with a maximum power of 462 HP, matching a 6-speed manual transmission.

  In 2001, the 911 Carrera underwent a mid-term change. First, the controversial "fried egg" headlights were replaced with the same sharp shape as the 911 Turbo. At the same time, the front safety was redesigned and the interior part was equipped with a more sporty three-spoke steering wheel. In terms of power, the 911 Carrera was replaced with a 3.6L horizontally opposed engine, and the maximum power was increased to 319 horsepower. In the same year, the fifth-generation 911 family also added the 911 Targa with semi-convertible design, and the 911 Carrera 4S with 911 Turbo appearance kit and upgraded suspension, braking and exhaust systems.

  In 2002, Porsche added the "X50" power enhancement kit to the 911 Turbo, which can increase the maximum engine power by 30 HP to 450 HP. In 2003, the 911 GT3 and GT2 were redesigned, and the engine power of the two cars was increased to 380 HP and 483 HP respectively. In addition, Porsche also introduced the 911 GT3 RS, which is closer to the racing car. Its most obvious feature is the red/blue rim, the hood and rear spoiler are made of carbon fiber, and the rear window is made of plastic.

Porsche Porsche 911 2004 Carrera Coupe MT 3.6L

  In 2003, it was the 40th anniversary of the 911 car series. For this reason, Porsche released the 911 Carrera "40 Jahre 911 ",a commemorative model with silver paint and a maximum power of 345 HP, with a limited production of 1,963 cars to commemorate the first year of 911. In 2004, the 911 series continued to introduce two new convertible models, the 911 Turbo Cabriolet and the Carrera 4S Cabriolet, providing customers with more choices. 2005 is the last year of the fifth-generation 911 life cycle. Porsche launched the ultimate version of the 911 Turbo S, which is basically equivalent to the 911 Turbo equipped with X50 suite. In addition, the car also comes standard with ceramic composite braking system. From 1997 to 2005, the fifth generation Porsche 911 produced a total of 175,262 units.

Return to Classic Round Lights —— 6th generation Porsche 911 (2004-2012)

Porsche Porsche 911 2005 Carrera MT 3.6L

  The 6th generation Porsche 911, code-named 997, came out in 2004. The new car is equipped with oval headlights, which not only shows the classic design style of the traditional 911, but also shows a new look of the new era 911. At the same time, the body width of the sixth generation 911 is 38mm wider than that of the previous generation, while the wheelbase is still 2350mm, and the drag coefficient is further reduced to 0.28. Although it has a brand-new appearance, for the whole 911 series, the sixth generation is only an evolution rather than an innovation, because it still comes from the same platform as the fifth generation 911.

Porsche Porsche 911 2005 Carrera MT 3.6L

  The interior design of the sixth generation 911 gives people a refreshing feeling, which is both luxurious and modern. The overall layout of the center console is regular, the functional areas are reasonably divided, and the overall sense of the central control panel is enhanced. The instrument panel still retains the classic design of five small dials, and the white characters on the black background are clear and easy to read. The three-spoke multi-function steering wheel adopts two-color matching with Porsche’s metal LOGO embedded in the middle.

At the same time, the 911 Carrera S coupe is launched, which is equipped with a 3.8L horizontally opposed engine with a maximum power of 355 horsepower. In the chassis part, the sixth-generation 911 continues to adopt the structure of front McPherson independent suspension and rear multi-link independent suspension, and is also equipped with Porsche Active Suspension Management System (PASM) for the first time.

Porsche Porsche 911 2005 Carrera MT 3.6L

  In 2005, Porsche introduced the 911 Carrera S Cabriolet, followed by the 911 Carrera 4/911 Carrera 4S with four-wheel drive. Through the multi-disc clutch, the front wheel can be distributed to 5 ~ 40% of the power output, and this version is suitable for both coupe and convertible models. In 2006, the 911 Turbo came out, and the brand-new fog lights and LED turn signals matched with the design of the large air intake to outline the unique front face shape. The rear spoiler is slightly lower than the previous generation, which has better aerodynamic performance. The power system is equipped with a 3.6L twin-turbo engine with a maximum power of 480 HP.

Porsche Porsche 911 2005 Carrera MT 3.6L

  In 2006, Porsche also introduced a high-performance version of the 911 GT3, which is equipped with a fixed rear spoiler that can increase the downforce. The powertrain of the 911 GT3 is equipped with an enhanced 3.6L horizontally opposed engine with a maximum power of 415 HP. In addition, the car comes standard with Sport mode. By pressing the SPORT button, the torque output of the engine can be instantly increased by 25 Nm from 3000-4200rmp. Subsequently, the 911 GT3 RS was 44mm wider in the rear wheel position than the GT3. In addition, the whole vehicle adopted a lightweight configuration, such as the adjustable rear spoiler made of carbon fiber and a lighter plastic rear window, which made the body lose 20kg compared with the GT3.

  In 2007, the convertible version of the 911 Turbo Cabriolet came out. Because of the special chassis reinforcement and the automatic extension rollover protection device installed at the back of the rear seat, the car was 70kg heavier than the 911 Turbo. In July of the same year, the sixth generation Porsche 911 has produced 100,000 vehicles, and the 100,000-th model is a red Carrera S with manual transmission. In September, Porsche introduced the more powerful 911 GT2, which is equipped with an enhanced 3.6L twin-turbo engine with a maximum power of 530 HP.

Porsche Porsche 911 2008 Carrera 3.6L

  In 2008, the sixth-generation 911 underwent a mid-term change. The biggest change of the new car was the introduction of DFI direct injection technology for the first time, and the first use of ZF’s 7-speed PDK dual-clutch gearbox. The adoption of new technology has a significant effect on improving the dynamic performance of the new 911. The maximum power of the 3.6L horizontally opposed engine equipped on the 911 Carrera and other models has increased to 345 horsepower; The 911 Carrera S and other models are equipped with 3.8L horizontally opposed engine, and the maximum power is increased to 385 HP.

The sixth generation 911 is in China.

Porsche Porsche 911 2008 Carrera 3.6L

  Porsche officially entered the China market in 2001, but Chinese people didn’t know the Porsche brand from September 11th. On the contrary, Cayenne and Panamera were more easily recognized by Chinese people. In 2005, Porsche officially introduced the sixth-generation 911 into the China market, with a price of 1.317 million. In order to meet the preferences of Chinese people, Porsche has launched models specially tailored for the China market, such as the Carrem Cup Asia Edition, which was limited to 30 cars in 2010, the 911 Edition Style, which was limited to 188 cars in 2011, and the 10th anniversary limited edition of 10 Porsche China specially built for the 10th anniversary celebration.

Replace the brand-new platform-the seventh generation Porsche 911(2011-present)

Porsche Porsche 911 2012 Carrera 3.4L

  In September 2011, Porsche released the seventh generation 911 with internal code 991. The new car comes from the third brand-new platform of the 911 series and is designed by Porsche Chief Designer Michael Mauer. Compared with the previous generation, the new 911 inherits the classic roof contour and arched front fender design, but it has higher aerodynamic efficiency and smoother body lines.

Porsche Porsche 911 2012 Carrera 3.4L

  The new car has widened the front wheel track and the rear spoiler that can be unfolded automatically. The wheelbase is lengthened by 100mm, the height is reduced, and the whole car is more sporty. The exterior rearview mirror has also been redesigned and installed at the top edge of the door. At the same time, the rear axle moved backward by 76mm, thus obtaining better front-rear counterweight ratio and curve performance. The new lightweight car body is also made of aluminum-steel alloy, which reduces the weight of the car body by 45kg, but greatly improves the stiffness.

Porsche Porsche 911 2012 Carrera 3.4L

  The interior of the new 911 has also been redesigned, which has a typical racing style. The position of the center console is raised forward, and the position of the shift lever is also raised accordingly, which is closer to the steering wheel, making the driver and the cockpit more integrated. At the same time, Porsche’s classic elements are also very eye-catching, such as the dashboard with five circular displays (one of which is a high-resolution multi-function display) and the classic mid-tachometer.

Porsche Porsche 911 2012 Carrera 3.4L

  In terms of performance, the new 911 Carrera, an entry-level model, is equipped with a 350-horsepower 3.4L horizontally opposed engine. When it is matched with a 7-speed PDK dual-clutch gearbox (a 7-speed manual gearbox can also be selected), it takes 4.6 seconds to accelerate from standstill to 100 km/h.

Millet: the first miscellaneous grain crop with "heavenly book"

Ripe millet. Photo courtesy of the millet variety exhibition base in Lvdian, Yichuan, Henan

What was the staple food eaten by the ancestors of Mentougou in Beijing more than 10 thousand years ago? What did Qinghai people use to make noodles more than 4000 years ago? 6,000 years ago, the population of the Central Plains increased greatly for the first time because of what crops?

Archaeology has proved that the answer is millet, which is commonly known as millet.

Recently, Nature-Genetics published online the first high-quality pan-genome map of millet completed by Diao Xianmin, a researcher at the Institute of Crop Science of Chinese Academy of Agricultural Sciences. This study not only proved that China is the only origin of millet from the genome level, but also created a precise and efficient breeding method of millet genome, which laid a theoretical foundation and provided a technical path for cultivating breakthrough varieties.

Li Jiayang, a researcher at the Institute of Genetics and Developmental Biology of Chinese Academy of Sciences and an academician of China Academy of Sciences, pointed out that this is the first high-quality map pan-genome in the field of coarse cereals, which is of special importance for future breeding applications. This achievement is not only another milestone in millet research, but also the best interpretation of "small crops, great achievements" and will bring important impetus to other crop research.

Identity change of millet

Millet belongs to the genus Setaria in Gramineae, which is the oldest domesticated crop in the world and the main crop formed in Asian/Chinese farming civilization.

The earliest millet found in archaeology appeared in the site of Donghulin in Mentougou District, Beijing, 11,500 years ago. There is no millet in Europe earlier than 3500 years ago.

Diao Xianmin, the correspondent of the paper, told China Science Journal that millet had long occupied the position of staple food in farming culture before the arrival of agricultural production system with high input (water conservancy, fertilizer and pesticide).

From Xia and Shang Dynasties to Wei, Jin, Southern and Northern Dynasties, millet has always occupied a primary position in grain. Especially in the Wei, Jin, Southern and Northern Dynasties, millet in the south developed unprecedentedly and reached the peak of historical prosperity. During the Sui and Tang Dynasties, millet entered the first recession, and the status of rice and wheat rose, replacing the traditional status of millet, forming a pattern of southern rice and northern wheat, but millet was still the core crop at that time.

Since modern times, with the breakthrough of green revolution of wheat, rice and other crops, the advantage of millet as a staple food has been gradually weakened. "In fact, it is only nearly 40 years since millet changed from a big crop to a small crop." Diao Xianmin said that Heilongjiang was the largest millet planting province in China in the early days of the founding of New China. In 1978, the millet planting area in Heilongjiang Province reached 20 million mu, but now the total millet planting area in China is only 20 million mu.

However, millet, the kernel of millet, has high nutritional value, which makes it a popular miscellaneous grain.

In recent years, with the increasingly obvious problems of climate change, agricultural sustainability and food security, scientists have placed new hopes on millet with the characteristics of drought tolerance, barren tolerance, strong environmental adaptability, easy transformation and easy laboratory operation.

Diao Xianmin has been engaged in millet research since 1987, and has collected more than 1,500 materials of Setaria from more than 20 species. "China’s millet farm varieties and bred varieties are the most abundant in the world. There are about 27,000 farm varieties, and the breeding level is the most advanced in the world. "

Diao Xianmin said that in order to make better use of these materials, it is necessary to accurately identify the genotype and phenotype of millet. "Now, compared with other big crops, the yield level of millet is still very low. The yield per mu of millet is generally 250 kg ~300 kg without watering and fertilization; Typical high-yield fields have water and fertilizer, with a maximum yield of 700 kg. This is mainly because we have no clear understanding of the population structure, evolutionary relationship and history of wild species, farm species and bred species of millet. "

These problems include that the level of genomic variation of millet is not very clear, especially there is no information on structural variation; The information of resource phenotype identification record is incomplete; It is not clear which genes, segments and loci have been selected during the domestication and breeding of millet. "This requires us to study more deeply."

Draw the first miscellaneous grains "heavenly book"

"The research published now is actually a part of the above-mentioned big project and a by-product. It is not decided to do it in a short time, but with the deepening of research and technological progress, it has been integrated with breeding and production needs and accumulated for a long time. Research results." As the chief scientist of the national millet sorghum industrial technology system, Diao Xianmin hopes to thoroughly understand the millet crop, and cultivate better varieties on this basis, so that millet can play its due role in the grain system.

Because of this, millet has become the first crop with map-pan genome in miscellaneous grains.

The so-called pan-genome refers to all the genetic information of a species, while the graph genome contains all the structural variations in the genome of a species. In other words, the map-pan-genome is the clearest, most detailed and comprehensive genome information of a species that can be drawn by using the current science and technology, which is equivalent to the "heavenly book" of the species genome.

Diao Xianmin’s team analyzed 1,844 core germplasm resources such as wild millet, farmed millet and modern bred millet, assembled 110 high-quality genomes of millet and Setaria from scratch, drew the first genome variation map of Setaria, recognized the basic situation of millet resource variation, and systematically analyzed the genome variation during the domestication and improvement of millet.

He Qiang, the co-first author of the paper and a postdoctoral fellow at the Institute of Crop Science, Chinese Academy of Agricultural Sciences, introduced that the species of Setaria could be clearly clustered by using high-magnification sequencing of 1844 core germplasm-foxtail millet and Setaria viridis. Among them, Setaria viridis is divided into 4 subgroups. Before Setaria viridis was domesticated into millet, there was an older subgroup C3, which was more geographically distributed and had stronger environmental suitability, which was of great significance for improving the environmental suitability of millet in the future.

Liu Xu, a researcher at the Institute of Crop Science of the Chinese Academy of Agricultural Sciences and an academician of the China Academy of Engineering, said that this confirmed the theory of the single origin center of millet, namely the origin center of China, and was a typical representative of resource research using new technologies.

Not only that, they also studied how millet was domesticated and improved. He Qiang introduced that they identified a total of 4582 structural variations related to millet domestication, 152 structural variations related to millet breeding improvement, and identified 680 structural variation-related genes that were continuously selected in domestication improvement, which were mainly enriched in metabolic pathways such as reproduction, photoperiod, pigment and nitrogen utilization.

2023 is the International Year of Millet. The Food and Agriculture Organization of the United Nations believes that millet deserves attention and has a place in people’s dietary structure, because millet can grow in harsh climatic conditions, which can help solve the problem of food shortage. Contribute to a healthy diet; Climate resilience; There is much to be done in improving the livelihood of small farmers; Xiaomi trade can enhance the diversity of the global food system; There are many innovative uses in the fields of treatment and pharmacy.

Diao Xianmin believes that publishing the map of millet pan-genome is the best support of China scientists for the International Year of Millet.

Establish a breeding database

It is already a huge task just to map the pan-genome. However, the team of Diao Xianmin did not stop there.

"What is different from other work is that we have done a lot of phenotypic identification." Diao Xianmin said that they relied on 17 units to investigate the basic agronomic traits of 680 materials and 22 environments in 13 places across the country for 10 years, which is the real multi-year and multi-point experimental data.

"We not only investigated the common traits such as plant height, panicle length, tiller number and grain weight per panicle, but also studied the drought resistance, grain dropping, beige color and grain quality traits in germination stage, seedling stage and whole life cycle, and formed 68 traits and 226 groups of phenotypic data, which is actually a phenotypic group." Diao Xianmin said that they focused on more practical character identification related to breeding. For example, they made a three-year drought-resistance survey in Xinjiang, a three-year drought-resistance survey in Shanxi, and a drought-resistance survey in Hengshui, Hebei.

More importantly, they also docked the two big data, the map pan-genome and the phenotype group, and discovered a total of 1084 phenotypic-related loci, of which structural variation accounted for 5.8%.

Tang Sha, the co-first author of the paper and an associate researcher at the Institute of Crop Science, Chinese Academy of Agricultural Sciences, told reporters that structural variation in the genome could not be seen before the genome was mapped. However, some important agronomic characters of millet, such as starch, flowering period and ear weight, are determined by structural variation genes.

"With these genes and their information, we can build a molecular breeding module. This information provides a method for genotype and phenotype mutual estimation and phenotype estimation by genotype, which is genome-wide selection breeding. " Diao Xianmin said that this is a database from which you can know what is the optimal gene for a certain trait. With this family background, good genes can be gathered together in breeding in the future, providing molecular and phenotypic basis for future breeding.

"This makes us more clearly see the importance of genome structural variation in discovering gene functions." Qian Qian, a researcher at the Institute of Crop Science of the Chinese Academy of Agricultural Sciences and an academician of the China Academy of Sciences, said.

Han Bin, director of the Center for Excellence and Innovation in Molecular Plant Science of China Academy of Sciences and academician of China Academy of Sciences, said: "The phenotypic prediction accuracy of whole genome selection in this study is over 90%, which shows us the application potential of whole genome selection in millet breeding. I think this research is not only a classic work of’ pan-genome-quantitative inheritance-breeding’ in millet but also in crop field, which has important guiding significance for future crop genetic improvement.

Looking for romance in science fiction! Fuzhou Roadshow of Cosmic Exploration Editorial Department


1905 movie network news The national roadshow of the film "Recruitment Conference of Alien Liaison Officers on Earth" came to the sixth stop in Fuzhou, Fujian on March 23rd. The director, screenwriter, screenwriter and starring walked into the cinema and Fuzhou University to have close interaction with the audience. This coastal city located in the lower reaches of the Minjiang River is warm and humid, with evergreen seasons. The beautiful and rich mountains and rivers must be pregnant with many interesting souls, which can resonate with the unique frequency of movies.

At the event, the audience enthusiastically shared their feelings of watching movies. "Science fiction films can still be so grounded, this is called comedy!" "I didn’t expect serious nonsense to be so funny, which is very humorous with postmodern splicing structure", "Poetry and aliens really don’t contradict each other at all", and the audience sincerely said that "one brush laughed, and after two brushes, the friend cried and said: He is just looking for an answer. I also cried. " The audience’s love and support for the film also touched and encouraged the main creators. Director Kong Dashan said: "You see a group of people in the film have a rough road, but in fact we are much worse than them when shooting." "If you can get some comfort from it, I think it is the meaning of this film."

The film "Cosmic Exploration Editorial Department" was produced by, supervised by, directed by Kong Dashan, starring, and starring Wang Yitong and. At present, the pre-sale of the film has been officially opened and will be released nationwide on April 1.

"Laughter at the scene almost knocked the ceiling off" Fuzhou, the roadshow of the film "Cosmic Exploration Editorial Department", stood in science fiction looking for romance.

On March 23rd, the national roadshow of "Space Exploration Editorial Department" and "Recruitment Conference of Alien Liaison Officers on Earth" came to Fuzhou, the sixth stop. Director and screenwriter Kong Dashan, screenwriter and starring Wang Yitong continued to look for people with the same frequency at the end of the universe. When watching the movie, the laughter at the scene came one after another. "I haven’t seen anything so funny for a long time," one audience jokingly described, "The laughter at the scene almost overturned the ceiling." "The director creates an absurd sense of joy with the huge difference between the hero’s reality and ideal, but he makes no secret of his sympathy, like singing an idealist’s sad song in a light tone, so the audience can always taste the thick sadness while laughing, which is very attractive." Another viewer directly classified Cosmic Exploration Editorial Department as "absurd science fiction", saying that the film allows everyone to "capture the truth and love of human nature from seemingly absurd daily life". "When you think it’s a layer of scams, it turns out to be the only way to the truth," she said emotionally. "This may also be a unique romance and helplessness of this film."

Many viewers were amazed by the performance of Wang Yitong, the screenwriter and star of Cosmic Exploration Editorial Department, in the film. I hope he can "quickly publish a collection of poems" and say that he is not only "well written in poetry", but also plays a very attractive role. "Wang Yitong himself made me want to see Sun Yitong again," an audience immediately said. "Even if it’s just to listen to him recite poems in Sichuan dialect, I have to brush it again." In this regard, Wang Yitong said that he was actually writing a poem for Sun Yitong, who lived in a very limited environment, but "has been receiving cosmic signals", so he used the romantic form of "poetry" to express his feelings from "all kinds of chaotic information".

"Even if you fall to the ground, you should look up at the starry sky." Fu college students found a brand-new hidden egg and were praised by director Kong Dashan.

At the post-screening event of Fuzhou University, a classmate couldn’t wait to share her feelings with the main creators, as if the film had opened a new world for her. "Now the Internet likes to use’ science fiction movies’ to describe romantic love." Then remove the science fiction elements in the film. "I think this is still a real’ science fiction movie’ because it makes me feel the ultimate romance and I want to cry when I watch it." She said that she really liked the part where the leading group got lost in the jungle, which was very "Peach Blossom Spring". A few people walk along a winding path of a stream, which is very poetic. " Another sharp-eyed classmate found a brand-new hidden egg in the film the first time she watched the movie. Listening to her analysis, Director Kong Dashan nodded frequently and cast an approving look. "You are the first person to find it, and it is better than what I want to say. Thank you very much."

At the event, a senior three director also came. He said that he really liked movies and wanted to enter the Beijing Film Academy to become the younger brother of director Kong Dashan. He said excitedly that although "the exam was not very good, I once thought about it or gave it up, but I am very grateful to the director for this film, which has strengthened my belief in being a preparatory filmmaker." The founders were also touched by his words, encouraging him to stick to it, as another audience shared, "When someone finally achieved his dream, he not only lit up his own life but also lit up others’ lives". I hope everyone can find their own direction when they are confused, as a film review that director Kong Dashan likes very much said: "Please follow the guidance of what you love, because that is the answer."


Korean media criticized Korean dramas without textual research, humiliated China and encouraged anti-Korean sentiment.


  The TV series Cain and Abel (I) has been criticized for depicting Shanghai, China as dark and backward. The TV series East of the Garden of Eden (Part II) once attracted attention because of its luxurious location, but it was criticized because the second half was too rough. /Chosun Ilbo


  Wang Si, a special correspondent of the Global Times, reported that the Korean Chosun Ilbo criticized the recent "unverified story of insulting China" in South Korea, saying that unverified Korean dramas can only encourage anti-Korean sentiment.


  Chen Junjie, press officer of the Korean Embassy in South China, said that he couldn’t help being angry after watching the SBS TV series Cain and Abel recently. He said: "Don’t screenwriters write works without textual research? Shanghai in the play is not so much the scenery in 2009 as the 1960s. It is unbelievable to describe a modern city like Shanghai as a backward old city. "


  More and more people point out that a thorough textual research is needed to keep the Korean Wave flowing. A careless description of Japan, China and other neighboring countries will inevitably be condemned for "distorting culture and history". Korean media are worried that the export of Korean dramas will also be frustrated.


  The Korean media quoted the Global Times report entitled "Korean TV series distorting China" in March this year, saying that the scenery of Shanghai, China in SBS TV series Cain and Abel was portrayed as a backward scene in rural China in the 1960s and 1970s. "There were even scenes in which violent gangs in China shot people in broad daylight and the police in China poured water on Su Zhixie for torture, which was totally impossible in reality."


  Chosun Ilbo said that the film crew explained that Shanghai was described as dark and horrible in order to emphasize the plot in the play. Cain and Abel is a story in which an elder brother tries to kill his younger brother for his own inheritance. The film crew said that such a scene was made to "emphasize the suffering of the protagonist wandering in do or die", but China protested: "It is a distortion to make a TV series without textual research, and no matter how clever it is, it can’t be forgiven."


  Korean historical dramas have also been criticized by China media. In SBS TV series "Yuan Gai Su Wen", there is even a "mistake" that Mao Zedong signed on the screen behind Emperor Yangdi’s seat. The Embassy of China pointed out that more Korean historical dramas were produced without interviews about the size of China Palace or the appearance of prisons. Therefore, some people even suggested that "a visiting program should be launched to organize Korean playwrights to come to China to learn about the culture and history of China".


  The article also said that South Korea’s MBC TV series "East of Eden" earned about 5 billion won by export. At first, the play attracted attention for shooting the location of Macao directly, but in the second half, streets in South Korea replaced Macao to save production costs, which caused criticism.


  In December 2008, the car chase and gun battle on the outskirts of Macao was broadcast, but its background was the winter scene in South Korea. Cui Yonghao, vice president of the Korea Cultural Industry Promotion Agency, said: "To continue to develop Korean TV dramas, we need to work hard on historical research and screen editing."


  Chosun Ilbo appealed that in order to export Korean dramas to Asia, Korean screenwriters should also change their perspective of observing Asia, instead of describing Macau as a gorgeous gambling city and Hong Kong as a dark alley, they should actively understand and explain the history and present situation of Asian neighbors.
