　　[car home Technology] Cadillac XTS is here. Believe it or not, this time, it seriously sent an afternoon letter to Audi A6L. It is natural to be prepared for such a high profile.

● engine

◆ 2.0T engine

　　Cadillac XTS models sold in China will provide two choices: 2.0T engine and 3.6L naturally aspirated engine. From the product information (2.0T Elite, 2.0T Luxury, 2.0T Premium, 3.6L Platinum), models equipped with 2.0T engines will become the main sales force. Can this 2.0T engine with the title of Ward’s Top Ten Engine provoke this girder? Let’s take a look at it.

　　This LTG 2.0T engine is very dazzling in terms of data. Even for the models listed in China, after localization adjustment, the 2.0T engine still retains 267 horsepower, which is not easy for a production car.

　　In fact, these technologies are not enough to make this 2.0T engine stand out among all sentient beings. Only data can explain its power. EA113 engine (mounted on Audi TTS) with the same level is obviously not as trendy as LTG engine, while Mercedes-Benz, BMW and other similar products are technologically advanced, but they have no courage to push the data to a higher level. I think this is the value of the 2.0T engine code-named LTG. According to GM staff, this engine will become exclusive to Cadillac brand in China market.

◆ 3.6-liter naturally aspirated engine

　　Among the four models, except for three models with 2.0T engines, Cadillac XTS also provides a model with a 3.6-liter naturally aspirated engine. Judging from the type of engine, this engine obviously pays more attention to the more linear power output.

　　From the parameter point of view, compared with the cylinder diameter, the shorter stroke makes the engine better at running at high speed, which is beneficial to the transmission of power in a more linear way. Although the efficiency is not as good as that of the 2.0T engine, the engine is more in line with the positioning of Cadillac XTS in terms of working characteristics.

　　In terms of engine technology application, this LFX model 3.6-liter naturally aspirated engine can also be called the mainstream. The addition of in-cylinder direct injection system can get a larger compression ratio for the engine, so as to improve the working efficiency of the engine. In the traditional sense, the V6 engine has stronger power and smoother operation, but the problem of self-weight is always an unavoidable disadvantage. However, with the improvement of engine manufacturing technology, the engine weight can also be controlled by using more integrated components, and so is this V6 engine. The weight of 157kg relieves the pressure of the front suspension to a certain extent, and the handling performance will benefit.

◆ The naming rules of the rear logo have changed.

● base

　　There are also some bright spots in the suspension structure of Cadillac XTS, such as Hiberstrut front suspension structure evolved from McPherson structure and the combination of MRC active electromagnetic induction suspension system and rear axle air spring. These chassis technologies really add a lot of color to Cadillac XTS. It is worth mentioning that although the models to be sold in China are not equipped with four-wheel drive systems for consumers like the overseas models, we also have reason to look forward to its arrival.

◆ Hiberstrut front suspension structure

　　Hiberstrut’s front suspension structure evolved from the widely used McPherson style. Compared with the front suspension with double wishbone structure, the traditional McPherson front suspension has the advantages of compact structure, lighter weight and faster response speed in handling. However, due to the lack of sufficient lateral positioning parts, the lateral rigidity is low and the handling stability is poor. In addition, the traditional McPherson structure can not play a good role in restraining the torsion steering caused by unequal length semi-shafts. The structure of Hiberstrut well neutralizes the advantages of McPherson structure and double wishbone structure, that is, it controls the weight and improves the stability of handling.

　　From this comparison, we can see the difference between the Hiberstrut structure and the traditional McPherson structure. On the basis of the McPherson structure, there is an additional fixed point between the steering knuckle and the steering column, and a short control arm is responsible for the lateral positioning at the upper end. This design concept is similar to that of the double wishbone, except that the structure is more compact and the weight is lighter. In addition to strengthening the fixing rigidity, different steering knuckle fixing methods lead to the change of the kingpin inclination angle, and the smaller kingpin inclination angle makes the wheels of the vehicle have better fit with the ground when turning, thus improving the handling performance of the vehicle in corners. The reduction of the kingpin inclination angle also affects the alignment performance of the wheel to a certain extent, and of course, it can be improved by matching with the steering assist system.

　　Not only the structure is simplified, but also the front suspension of Cadillac XTS is made of aluminum, such as the bearing seat and the strut at the lower part of the shock absorber.

◆ Brembo four-piston calipers are standard for all front brakes.

　　Brembo four-piston calipers are the standard configuration of all Cadillac XTS models. Compared with competing models of the same class, this performance-oriented configuration is really rare.

◆ Adaptive chassis

　　In addition to structural optimization, Cadillac XTS is also equipped with a set of MRC active electromagnetic induction suspension system in the chassis, which can adjust the damping of shock absorber in real time according to the driving mode options and actual driving needs. Not only that, the air spring also appears in the rear suspension part. However, these configurations will only be available in 2.0T premium models and 3.6L Platinum models with 3.6L engines.

　　The piston rod of the shock absorber is equipped with an electromagnetic coil, and the magnetic fluid in the shock absorber is a suspension liquid in which magnetizable soft iron particles are suspended in hydrocarbon solution. When the electromagnetic coil is energized, the magnetic field formed makes the iron particles form a fiber structure arrangement along the fluid direction, and the strength of the combination between particles in the structure is proportional to the strength of the magnetic field, so the damping performance can be changed only by changing the current.

　　The system collects information at a frequency of 1000 times per second and reacts quickly, so as to ensure that some unnecessary sloshing is filtered when the vehicle is driving on complex roads, so that the shift of the center of gravity of the vehicle body and the degree of pitching forward and backward can be effectively controlled, and the contact between the tire and the ground can be increased as much as possible. This control logic is also useful in the process of intense driving and after making emergency avoidance actions.

　　Different from the combination of spiral spring and variable damping shock absorber used in the front damping mechanism, the air spring is selected as the elastic element of the suspension in the rear damping mechanism of Cadillac XTS. I think this is also due to the consideration of ride comfort. After all, XTS has locked in the field of executive cars, and the ride feeling in the back row should be taken seriously. Of course, the coordination of air spring and variable damping shock absorber is also very direct for the control of body posture. In addition, it is also an advantage to adjust the horizontal position of the car body in real time according to the changes of the car body load and road conditions.

● safe practice

　　The ESS enhanced safety strategy built on Cadillac XTS has attracted many technologies to improve driving safety, most of which are active safety technologies. Of course, passive safety technologies are also superior in the same class cars. It must be mentioned that Cadillac XTS comes standard with 10 airbags.

◆　Active safety technology

Forward collision warning+road deviation warning

　　We are familiar with these two technologies, which were introduced in detail in "The Third Eye to Analyze the The Secret Behind of the Central Rearview Mirror". Indeed, the best way to improve driving safety is to nip the collision accident in the cradle, and effective monitoring is the key.

　　The camera installed on the front windshield can take 12 high-definition photos every second, and the image information is analyzed by image comparison software to confirm the real-time situation before getting off the bus in driving state. When it is found that the vehicle is too close to the vehicle in front or the vehicle tends to deviate from the lane, the system can use the indicator light, buzzer and seat with vibration warning function to send a warning to the driver in an effort to make the driver pay more attention. Unfortunately, these two active safety systems only have prompt function at present. It is worth noting that these two functions will be activated only when the vehicle speed reaches the working conditions of the system.

　　It is not Cadillac’s initiative to remind drivers by vibration. We have introduced the steering wheel vibration reminder in related articles before, and Citroen C6 also uses seat vibration to remind drivers. However, in contrast, XTS’s vibrating seat is more comprehensive in mode, and the vibration can appear in the left rear, right rear or both sides of the cushion, and the vibration in different positions represents warnings from different directions. Cadillac engineers believe that this reminder with direction indication is more effective than the traditional buzzer.

●　Man-machine interaction system

　　In my impression, compared with other brands of cars, German brand cars have more profound attainments in human-computer interaction system. However, now more and more manufacturers are starting to build their own human-computer interaction systems. Unlike the former, they prefer to realize some ideas with a basic and mature system architecture. The CUE system of Cadillac XTS belongs to this category, and the resulting experience is really different from others.

◆ Focus on user experience

　　CUE system began to be developed in 2008. In order to create a revolutionary experience, in the research and development stage, the system designer conducted a follow-up survey of 32 drivers for half a year and recorded their driving habits one by one. Then, engineers and designers conducted research and development based on these summarized data and corresponding technologies, and finally integrated the CUE system with the vehicle through modeling, visual feeling of the screen and touch feeling.

　　The traditional physical buttons can’t be found in the center console of Cadillac XTS, and the control panel is changed to the same capacitive touch technology as the display of the center console. Although this is rare in cars, most people can adapt to this operation mode quickly. After all, it is not much different from the electronic products you play with all day except the size. In order to counteract the fuzzy feeling of the touch panel during operation, the system gives a certain feedback effect by vibration, but to be honest, I don’t like this slightly abrupt vibration feeling very much. Unfortunately, the system does not support the function of adjusting or closing the vibration intensity.

◆ Development of operating system based on Linux

　　CUE system is developed based on Linux operating system, and the familiar Android system occupies most mobile terminal devices except Apple. From the daily experience, the platform of Android system is more flexible, which means that there are more choices in the use of application software. For Cadillac’s CUE system, it can connect with the mobile phone via Bluetooth, and use 3G network to download the application software needed by individuals. In order to ensure the security of the system, all software from third parties need to be certified by Cadillac before it appears in the download interface.

　　At present, the development authority of the application software around the CUE system has not been fully opened to the outside world, so its advantages cannot be released for the time being. However, the 8-inch multi-touch LCD screen is ready for this purpose, and the page-turning ability of supporting up to 5 screens is comparable to that of mobile phones in terms of code placement of application software. But from another perspective, how many third-party software development organizations will CUE attract? This has a great relationship with the coverage area of CUE system.

◆ Two-picture information flying interaction

　　The design of screen and software is the key to improve the experience, and the hardware is the foundation to realize all this. CUE system adopts ARM11 series of three-core processors, which are widely used in smart phones. This makes the CUE system more comfortable in running application software, navigation and picture processing of display screen. However, in the process of operation, finger movements and screen changes are not as smooth as smart phones such as iPhone.

　　The all-digital instrument and the center console display screen, which can realize the flying interaction of double-screen information, are one of the highlights of the CUE system. By using the touch technology and the data interaction between the two displays, the driver can move the information in the center console display screen to the all-digital instrument for display, and this process only needs the finger to move. This unprecedented experience can really make people shine.

◆ All digital instruments support four background modes.

◆ Entertainment function

☆ Seamless connection with the mobile terminal is realized.

　　Let’s take the mobile phone as an example. After connecting with the mobile phone through Bluetooth, the CUE system will integrate the information in the mobile phone. In addition to the phone book information, music files will also be classified. Moreover, the list of online music such as QQ music will also appear in the entertainment files of the CUE system, which embodies the concept of "cloud".

☆ Rear row equipment

　　The entertainment function of the CUE system itself is also very powerful. The central control display screen and the rear display screen can play different video contents through the Blu-ray drive or other external media devices installed in the glove box. In my opinion, this is very good, but if a split-screen display is needed in an actual car, more demand may be two passengers sitting in the back row, just like video equipment on an airplane. Since each seat is equipped with a display screen, the passengers in the back row will feel somewhat disappointed when they find that they need to accommodate each other during the video playback. Of course, two people watching the same content will also produce more common topics.

● Other details

◆ Active noise reduction and mute system

　　In order to improve the quiet degree in the car, Cadillac XTS is equipped with an active noise reduction and mute system (ANC) provided by Bose. When the system detects the presence of noise, the BOSE sound system assembled in the car emits sound waves in opposite phase to the noise, so as to cancel the noise in the car. This set of active noise reduction technology from audio is also used in headphones.

◆ Multi-directional channel adjustment

◆ Glove box with password lock

　　Cadillac XTS also installed a password lock for the glove box by using CUE system. When lending a vehicle to others or sending it for repair, you can protect your privacy through an encrypted glove box. The encryption is set to be one-off, and the previously set password will be invalid after the owner successfully unlocks it, which is similar to the safe in the hotel.

◆ Head-up display

◆ Parking aid system

◆ on star

Editor’s summary:
　　Americans seem to have more say in the creation of user experience, which is more felt by European mobile phone manufacturers who once thought they would last forever. Which field will be subverted next? Vehicle man-machine interaction system? The emergence of the CUE system is expected to break the tripartite confrontation of German cars in the field of human-computer interaction system. However, it is not yet time, because from the actual experience, although it has certain expansion ability, the operation fluency of the CUE system has not reached my expected effect (the previous publicity mostly compared with Apple products, which invisibly raised people’s expectations for the CUE system). If it can be further optimized in hardware and software, it may really be deeply rooted in people’s hearts over time. It can only be said that the CUE system adds a lot of color to Cadillac XTS.

　　At the beginning of the article, it is said that GM has found a strong rival for Cadillac XTS in China market-Audi A6L. At present, the BMW 5 Series is the most threatening car to Audi A6L. Although Cadillac is both high-end in brand value and XTS is also striving to build its sense of science and technology, the products of these two brands are completely different in China market. What will impress the consumers who need medium and large luxury cars? This question really needs deep thought. (Photo/Text car home Li Boxu)

● Automobile technology is difficult to understand? Car design is too far away? Who said that? These contents can also be very interesting!

> > Want to know more about cars and become a talent? Let’s go to car home Science and Technology! <<

　　　　 Recently, the auto market talked about it from relevant channels. Roewe D7 will be officially launched on November 8th, and both pure electric (EV) and plug-in hybrid (DMH) models will be launched simultaneously.

　　　　 As a sedan chair with high and medium-grade new energy strength, what is the strength of Roewe D7 and what are its leapfrog values?

　　　　

　　　　 Leapfrog value one: comfort

　　　　 Aside from the fact that different people have different opinions, the first "killer" of Roewe D7 is comfort.

　　　　 Roewe D7 has carefully built the Yunsu intelligent cockpit, which is the best in its class with the widest body, the most advanced intelligent cabin, the best seating space and the most comfortable seats.

　　　　

　　　　 Specifically, the Roewe D7 car is 4890mm long and 1890mm(DMH wide (DMH model), all of which are leading in the same class, which not only makes the car body more magnificent, but also brings the best riding space.

　　　　 Its front seat cushion is 380mm long, and the rear leg space is 933 mm. With the zero-gravity cloud seat, the comfort is the ultimate.

　　　　

　　　　 It’s not enough to have a big body and a large space. Roewe D7 is also equipped with the latest zebra intelligent driving system in the world, and its operating experience is comparable to that of high-end smart phones. It can be said that it is the "most user-aware" in-vehicle system in the current automobile market, which brings native comfort and is equipped with L2-level intelligent driving assistance such as ACC, ICA and AEB lane departure warning, making travel more efficient.

　　　　 Leapfrog value 2: reliability

　　　　 Nowadays, buying EV models is no longer paying IQ tax, but try not to buy "oil to electricity" models. After all, the problems of poor power, short battery life and low safety of such vehicles are widespread.

　　　　 As the first model of Roewe D family, the EV model of Roewe D7 is built on the exclusive platform of SAIC Nebula pure electricity, which is very reliable.

　　　　

　　　　 The development concept of Xingyun pure electric platform is "gradient, expandable and iterative upgrade", which can be compatible with software and hardware forward-looking technologies such as high-pressure casting, solid-state batteries, wire-controlled chassis, full-stack electrical architecture and driverless driving, and embodies the highest level of "China Zhizao" in the automobile industry.

　　　　

　　　　 Based on the advanced platform strength, Roewe D7 EV has a high-end model "the same model" with five-bar rear drive, VGA six-in-one motor with the highest integration level, more and larger bushings, etc., which has strong power and brings better control experience, making it the most stable pure tram in its class.

　　　　 Leapfrog value three: great value

　　　　 I have to say that plug-in models are very popular nowadays. Roewe D7, based on the most long-term value of DMH hybrid technology, launched the "China’s strongest hybrid" DMH model that surpassed DM-i, which can meet the needs of different users.

　　　　

　　　　 The reason is that the Roewe D7DMH adopts the industry’s first powertrain brain PICU, which realizes the "five-in-one" functions of motor control, engine control, hybrid gearbox control, air conditioning thermal management and battery thermal management, and its dynamic response is twice as fast as that of Qin PLUS DM-I..

　　　　

　　　　 Moreover, the Roewe D7DMH model is also blessed by a coaxial P1 motor, a hybrid engine with a thermal efficiency greater than 43%, and a dedicated high-efficiency long-life battery, which makes it have the advantages of long battery life, ultra-low fuel consumption, super quiet and so on, and it is the strongest hybrid in its class.

　　　　

　　　　 On the whole, the Gemini combination of Roewe D7 EV and DMH is expected to become the most powerful sedan with medium and high new energy strength in China.

　　　　 If you are more pursuing power and control, it is recommended to choose Roewe D7EV model. If you pursue both dynamic performance and economy, it is recommended to choose Roewe D7 DMH.

Low fuel consumption is very attractive to many office workers. After all, what they think about when they commute to get off work every day is definitely not power control, but saving money and ensuring basic transportation needs. What I bring to you today is that it has many highlights. As for its advantages, please take a look.

Take a look at the appearance of the Xingtu Lanyue first. The front face of the Xingtu Lanyue looks very full, equipped with a multi-spoke midnet, which looks softer. Then the round and lovely headlight design is adopted, and the overall design is very soft. The car is equipped with LED daytime running lights, front fog lights, automatic opening and closing, adaptive far and near light, delayed closing, etc. To the side of the body, the body size of the car is 4970MM*1940MM*1792MM, the car adopts a stable line, the side looks very soft, with large-sized thick-walled tires, the overall visual effect is very clean and refreshing. On the rear design, the Xingtu Lanyue rear line is young, the tail lights are very full, and the unique exhaust pipe is very sharp.

In the car, the interior adopts a stable design and good visual effect. The steering wheel of the car is very fashionable and sporty, and it is made of genuine leather, which gives people a bright feeling. Let’s take a look at the central control, with a 15.6-inch touch LCD central control screen, the interior design is quite layered, in line with the aesthetic standards of most consumers. The dashboard and the seats are also eye-catching. The car is equipped with a personalized dashboard, and the trendy design elements make people remember it at a glance. The car adopts leather seats, equipped with functions such as electric adjustment of the auxiliary seat with memory, electric adjustment of the seat with memory, and seat ratio reclining. The materials are exquisite and the ride is comfortable.

Xingtu Lanyue matches the automatic manual (AT) gearbox, with a maximum power of 192KW and a maximum torque of 400N.m, resulting in good power performance.

The space performance of the Xingtu Lanyue trunk is OK. If there are large items on the road, you can put down the rear seats to meet daily use.

Our reporter, Ye Bihua, reports from Guangzhou

   
On April 11, Nongfu Spring, which was pushed to the forefront of the trend by the standard controversy, suddenly launched an attack, directly denouncing the recent series of attacks on Nongfu Spring as being planned behind the scenes by rival China Resources Yibao.

   
"As a state-controlled drinking water company, it is regrettable that it uses public fears about food safety and environmental pollution as a marketing tool to target competitors and expand market share," Nongfu Spring said in a statement on its official Weibo account.

As of this writing, China Resources Yibao has not made any response to this.

   
In the first three quarters of 2012, among the top four sales of drinking water in bottles (cans) in China, Nongfu Spring ranked first in the country with a market share of 35%, leaving behind the second-placed Master Kong by 19 percentage points. But at the same time, a series of negatives such as "Water Source Gate", "Fake Donation Gate" and "Arsenic Gate" have been surrounding this drinking water market leader. Just recently, some media reported that Nongfu Spring’s standard is not as good as tap water, which once again triggered the public to rethink the drinking water source.

standard doubt

   
On April 8, some media exposed that Nongfu Spring used "DB33/383" Zhejiang local standards in the three major water sources of Wanlv Lake in Guangdong, Qiandao Lake in Zhejiang and Danjiangkou in Hubei, which is far lower than the "DB44/116-2000" Guangdong standard. Nongfu Spring is suspected of avoiding the use of standards. At the same time, Nongfu Spring also participated in the formulation of Zhejiang standards.

   
According to our understanding, compared with the Guangdong standard, the Zhejiang standard used by Nongfu Spring has twice the tolerance content of cadmium, arsenic and other harmful substances than the Guangdong standard. The Zhejiang standard tolerates the existence of fungi such as mold and yeast, while the Guangdong standard is "not detectable".

   
Subsequently, some media quoted Zhou Xiaolin, director of the Food Supervision and Administration Department of the Zhejiang Provincial Quality Supervision Bureau, as justifying the matter. According to the report, Zhou Xiaolin showed reporters the national standard GB19298-2003, the Zhejiang Provincial Standard DB33/383-2005 and the Guangdong Provincial Standard DBS44/001-2011, and said that the microbial indicators in these three standards are exactly the same.

   
But in fact, the national standard of "Bottle (Barrel) Drinking Water Hygiene Standards" mentioned by Zhou Xiaolin has been revised in January and September 2008, and the revised national standard is stricter than the Zhejiang standard. With the continuous fermentation of public opinion, Nongfu Spring finally responded to various doubts on the 11th.

   
"The arsenic and cadmium levels in Nongfu Spring products are below the detection limits, and the levels are so low that they cannot be detected. Mold and yeast are also undetectable." In its statement, Nongfu Spring did not provide a detailed explanation of the standard issue, but turned its attention to competitors. "We have reason to believe that the recent series of reports against Nongfu Spring are deliberately planned, and behind the scenes is the state-controlled drinking water company, China Resources Yibao."

Benchmarking Yibao

   
In the statement, Nongfu Spring cited negative online media coverage of its products since March 15, as well as a series of marketing campaigns by rival China Resources Yibao, and claimed that competitors had hired personnel in Hunan, Guangdong, Sichuan, Chongqing, Hubei and other places, and distributed articles attacking Nongfu Spring door-to-door to retail stores and consumers.

   
Luo Tan, president of the Guangdong Bottled Drinking Water Industry Association, told our reporter that Nongfu Spring is currently at the forefront of the bottled water market in the country, especially in the East China base camp, and has an absolute advantage. But in southern China, Nongfu Spring has to face competition from brands such as Yibao, Jingtian, Yili, and Watsons. Among them, Nongfu Spring and Yibao have the most intense competition in the Shenzhen market.

According to our understanding, the main product of farmers’ bottled water
At present, the price of 550ML in Guangzhou supermarkets is about 1.2-1 yuan, while in Shenzhen supermarkets in recent months has maintained 1.8-1 yuan/bottle, the price is close to the main competitor Yibao.

   
"Farmers seven or eight years ago had relatively good price maintenance, but with the rise of Master Kong and competition from other brands, farmers in southern China had to cut prices in exchange for market share," a drinking water company executive told the Financial Times on condition of anonymity.

   
According to it, the total bottled water market in Shenzhen rose by 11% last year compared with 2011, of which Nongfu Spring rose by 45%, and Nongfu’s bottled water market share in Shenzhen also jumped from 9% in 2011 to 12% in 2012.

   
China Resources Entrepreneurship (00291.HK), the parent company of Ipoh, reported last year that although it benefited from the rapid growth of sales and turnover of Ipoh pure water in Guangdong, Hunan, Sichuan, Jiangsu, Guangxi and Fujian, the total sales volume of the company’s beverage business in 2012 increased by 33% compared with the previous year to about 3507,000 kilolitres, with a turnover of 47.66 million Hong Kong dollars, an increase of 53.1% year-on-year, but the profit attributable to it decreased by 31.7% compared with 2011 to 86 million Hong Kong dollars.

   
The above-mentioned water company executives believe that the profit margins in the bottled water industry are currently very low, and for most brands, it is impossible to continue the downward price war.

Water source dilemma

   
From the original "Water Source Gate", "Fake Donation Gate", "Arsenic Gate", to the current "Standard Gate", water sources have always been the main aspect of Nongfu Spring’s criticism by the outside world. If the price cannot be beaten by Master Kong, the drinking water market can only go up the high-end route, and there are a variety of claims such as natural pure water and mineral water, but in the end, water sources are the commanding heights of major enterprises.

   
At present, the three main water sources of Nongfu Spring (Wanlu Lake in Guangdong, Qiandao Lake in Zhejiang, and Danjiangkou in Hubei) are basically lake water, which belongs to surface water. Nongfu Spring adopts the direct canning method, which is physically filtered according to certain standards (usually activated carbon and sand cans). If the water contains heavy metals, it cannot be filtered, and can only be controlled by the water quality of the water source itself.

   
"But from a natural science perspective, the control of lake and reservoir water has limitations." The above-mentioned water company executives believe that the so-called water source protection area is just a series of mandatory protection measures taken by the state for it. Compared with other water sources, the protection of water sources is much greater, but it does not mean that this water source is completely controlled.

   
In the opinion of the above-mentioned water company executives, it is already very difficult to find high-quality water sources, and even more difficult is how to maintain the water sources later.

   
"So far, the state’s supervision of agriculture has not been able to avoid the use of chemicals that affect human health, and these chemicals will gather in the catchment area with natural rainfall, so basically, if the unit that uses these water sources can control the safety of the water source 100%, I think this is a bit too much, it is impossible to do this," the water company executive said frankly.

   
Previously, some media went to the Danjiangkou Reservoir to investigate and found that there were all kinds of domestic waste on the shore around the water intake point of Nongfu Spring, but the staff of Nongfu Spring Factory said that the domestic waste had little impact on the water quality, just like "the sand in the rice".

Jackie Chan

Samuel Hung

Producer Chen Guoxin

Movie Network News(Text/Zhao Jin, Photo/Yang Liu) On October 18, all the creators of "The Wushu Youth Tour" appeared in Beijing to build momentum for the film’s release. The appearance of the film’s producer Jackie Chan and star Hong Jinbao became the focus of media attention. The main actors of the film were selected as first-class newcomers in the film industry. The whole film was shot without a double, and the footage showed real kung fu scenes. "The Wushu Youth Tour" will be fully released on October 24.

Samuel Hung "challenges" Jackie Chan, calling 40-year friendship "abnormal"

Jackie Chan and Hong Jinbao came from the same school and have known each other for more than 40 years. The two were quite familiar at the scene. You argued with me and exposed each other’s "old background". Jackie Chan recalled that he was very hard to practice kung fu in his childhood, and he was often beaten by his master. Senior brother Hong Jinbao repeatedly corrected Jackie Chan’s words and ridiculed Jackie Chan for being "too unconscientious". Jackie Chan even "threatened" that in another 3 years, he would teach Hong Jinbao a good lesson.

Remembering childhood: Jackie Chan vomits bitterness, and Hong Jinbao is busy defending

"They are very happy now, we were very miserable at that time," Jackie Chan recalled at the scene when he learned martial arts in his early years, "We lived in a very bad environment at that time, we had to go to the Red Cross relief center every week to get food, and we had to queue up to get fresh water every afternoon. We didn’t have enough to eat and sleep, and Master often beat us."

Hearing this, Hong Jinbao immediately grabbed the microphone, "Jackie Chan, don’t speak ill of your master, we were lucky to be able to learn martial arts at that time," he also explained: "Although our master is poor, he never received a penny from us. Although the master is strict, the old-fashioned way of teaching is like this. And he loves you the most, and he recognizes you as his godson." Jackie Chan called Hong Jinbao at the scene and misunderstood his original intention, "Hong Jinbao, I must hit you, no, I will come back when you can’t hit me in 3 years."

Recently, at the 16th China Automotive Blue Book Forum, Autonavi Maps officially released AutoSDK 750 for the automotive industry, launchingNew energyNavigation, multi-scene lane-level safety warning, lane-level navigation 5.0, co-pilot screen weekend travel assistant, driver interconnection seamless connection experience, scene engine quick departure and other functions have been updated.
