Special feature of 1905 film network After more than ten years of debut, Ada has gradually become a familiar host for the national audience and transformed from a host to an actor. Although he has acted in dozens of film and television works, Ada is still modest and enterprising when it comes to the identity of an actor.

In the interview, Ada said that he needed a masterpiece and an award. "I hope to be recognized by the industry so that I can announce loudly: Hey, I am an actor." At the same time, she is not in a hurry. "I won’t force myself to play a role that is particularly unlike me. I haven’t reached that skill and temperature yet."

Ada’s style is still sexy this time.

Ada said that he regarded opportunities as life. His friend Dapeng wrote in the book that when he was a newcomer, he made a program with Ada. Ada’s hard work moved him. In Pancake Man, Dapeng also used movies to let the audience see the helplessness of Ada’s efforts but being misunderstood.

In the interview, Ada revealed that he would also join Dapeng’s new film. Recently, when Dapeng announced in Weibo that the second film "Sewing Machine Band" was about to start shooting, Ada also said, "I want to go back to your 16-year-old and see that packed concert." Let people look forward to the spark of this good friend in the new movie.

Recently, a group of new car renderings have been circulated on the Internet. It is reported that this car is actually, according to the overall renderings, the design language of the front face of the new car is obviously different from that on sale. In addition, the M8 is equipped with laser radar and provides orange-red color matching, which is very advanced. The rear taillights also use the editable penetrating taillights of the same model as M9, which basically confirms that M8 is the positioning of the small M9.

The medium and large SUV positioned by M8 can be regarded as a small M9 from the body outline, so that the internal seating space of the vehicle is also guaranteed. The M8 of the vehicle adopts the design of short front suspension, which I believe will impress many home-oriented users.

At present, all spy photos exposed by M8 are not equipped with lidar configuration, which should be the difference of vehicle configuration. After the launch, the M8 high-profile models will probably use lidar, and will also be equipped with Huawei ADS high-order intelligent driving assistance, while the conventional low-profile models are estimated to only use Huawei Gankun ADS SE based on the visual scheme.

As for the interior, since it’s a small M9, it’s sure to follow M9′ s triple-screen interior design style. Of course, the details will definitely be optimized, such as the narrower black edge of the screen, the hollowed-out design of the central armrest to increase the storage space, etc. As far as design maturity is concerned, M8 is definitely a higher level, and M9 may not be able to use a new design until it is replaced.

Other configurations, such as zero-gravity seats and Divare audio, will not be absent from the M8. Of course, in order to meet the needs of different users, there will still be a high probability of 5/6-seat models in the future.

Competitive product analysis:

From the positioning point of view, the most direct competitor of the M8 is naturally the ideal L8. After all, the two cars are very similar in size, and they also focus on comfort and home use. In the future, they will definitely fight to the death.

Old driver’s spicy comment:

The launch of the M8 will undoubtedly further enhance the sales of the brand, and will add another fire to the domestic high-end new energy.

Important senior executives of Great Wall Motor leave their jobs, in the "time of war";

General Manager of Group Brand Public Relations — — Goldilocks, resigned and left. The Great Wall also responded:Personal reasons.

On the whole, he is the head of public relations marketing introduced by the Great Wall at the beginning of this year, and is also one of the important components of the comprehensive innovation strategy.

The moment when he was exposed to leave his job was an important pass for the Great Wall to "fight" BYD.

Who is Guo Tiefu?

When Guo Tiefu left, Great Wall Motor responded: I resigned for personal reasons.

However, he only joined Great Wall Motor in February this year as the general manager of brand public relations.

At most three months before and after, the executive with comprehensive experience in high-end, high-tech and new-force automobile marketing left the Great Wall.

Guo Tiefu has previously served luxury brands such as Audi, Bentley and Jaguar Land Rover. After that, he joined Baowo Automobile in charge of marketing.

In 2018, Guo Tiefu joined Chinese Express as the Senior Director of Gaohe Automobile Market and Public Relations Communication, and was fully responsible for public relations and communication. The brand tonality of high-tech sci-fi, advanced and luxurious is created by Guo Tiefu.

In 2022, Guo Tiefu briefly joined Lotus Motors.

Guo Tiefu’s resume is actually the core reason why the Great Wall took a fancy to him and introduced him. Long-term high-end brand marketing, and have more successful experience in building scientific and technological brands.

Wei, the high-end brand of the Great Wall, has been performing poorly in the past few years. In addition, for the new energy track, the Great Wall is also suffering from "technology without sound" and is suppressed by BYD in all aspects.

Therefore, Guo Tiefu joined the Great Wall. On the one hand, he cooperated with Liu Siying, who was dug from Geely Link, and made a breakthrough in the high-end brand Wei; And his main business is corporate brand and technology brands construction.

That is, since this year, Great Wall Motor has made a major change in external marketing, which is to emphasize the self-research and accumulation of technology as BYD, to shape its image as a leader in new energy and smart car revolution technology, and at least to form a double-walled image with BYD.

In fact, the post of general manager of brand public relations did not have a special post at Great Wall before, but only after the reform of the whole marketing system. Guo Tiefu became the first user of this new title.

In fact, this is part of the Great Wall’s strategy of learning from a painful experience and comprehensively transforming new energy sources.

Now, with the departure of Guo Tiefu, the construction of the Great Wall technology brands has become uncertain again.

Great Wall Motor and BYD’s "Public Relations War"

At present, the Great Wall is at the key node of the "war" with BYD.

Things, you have been clear:

Great wall purchased and sent for inspection by BYD, and mixed sales crown Qin PLUS DM-i and song PLUS DM-i,It is found that the low-cost atmospheric fuel tank is used, which makes the evaporative emission of the whole vehicle non-compliant.

So Great Wall Motor reported BYD to the regulatory authorities. BYD responded that the Great Wall is unfair competition, the inspection procedures are not standardized, and its own atmospheric fuel tanks also have technology to ensure emission compliance. The regulatory authorities did not declare the data evidence of the Great Wall invalid, but attached great importance to it and put it on file for investigation.

It’s not clear yet. It’s still fermenting. Netizens stood in line one after another, quarreling as a bee.

There is no doubt that the report itself was prepared and collected by the Great Wall a long time ago. Guo Tiefu, who has been talented for more than two months, is hardly the leader. His departure had little effect on the storm.

In fact, the fuel tank problem itself is an environmental protection issue, and the regulatory authorities are very concerned about it, butFor ordinary users, there is not much impact.

Judging from the results, if BYD really has a problem and is punished and recalled, it is equivalent to being slowed down objectively, which is also unfavorable in public opinion and has nothing to say.

If the supervision did not find out BYD’s problems, the Great Wall would not suffer. Return to the focus of new energy through BYD’s popularity and public opinion base.

In fact, it is better to understand this matter in this year’s Great Wall, a new energy strategy: new technology — — Hybrid electric four-wheel drive Hi-4, new brand channel — — Haval’s new energy and new products — — Hybrid dragon series, and new marketing promotion — — Advanced technology of great wall three power and hybrid technology.

The fuel tank problem was the first shot of the outpost and the counterattack against BYD.

Therefore, the impact of Guo Tiefu’s departure is medium and long term.

The sudden outbreak of BYD has been widely recognized by users. On the one hand, it is to make the hybrid car with low energy consumption and high configuration into cabbage price, which will form a dimension reduction blow to fuel vehicles.

On this basis, BYD spared no effort to preach its new energy leadership: battery acupuncture, DM-i, Yunqi, Easy Sifang and so on. With the expansion of new energy sales base, BYD has quickly established the impression of "the strongest technology" among ordinary consumers. Even if most ordinary users don’t understand technology at all, it is said that "it is not wrong to buy BYD with new energy".

At the same time, BYD also intends to portray itself as "the leader and hope of overtaking cars in corners in China". For example, Wang Chuanfu said with tears in his eyes that "it is not easy for us to make technological breakthroughs in recent years".

"We", Wang Chuanfu didn’t specify who it was. BYD, of course, and China automobile industry. In communication, BYD actively blurs the concept, and objectively, it is easy for ordinary people to have the impression that BYD is a new energy source in China, and even the only hope for China’s automobile to rise and overtake.

Not only the Great Wall, but also any independent brand with technical reserves, market scale and self-improvement ambition will not recognize BYD’s concept of shaping basic facts.

The fuel tank is an introduction. After the Great Wall, it will definitely emphasize its own technical reserves and self-research strength again and again, just like BYD did in those years, trying to compete with BYD in the wave of new energy and intelligence.

Guo Tiefu, who is the most critical to undertake this task, left his job at the juncture when the Great Wall is about to exert its strength.

The Great Wall’s counterattack and new energy strategy, now this variable comes somewhat unexpectedly and suddenly.

　　Beijing, 7 June (Reporter Ding Yazhen, Wu Yue) June 7 is the first day of the national college entrance examination.

With the development of new energy market, pure trams are getting more and more fierce, but they all seem to take intelligence and personality as their destination, such as GAC Aion Y, BYD Dolphin and Euler Good Cat, and each one is more beautiful than the other. Starting with pure trams seems to mean "consumption upgrade". In the era of oil trucks, there are actually many sturdy, durable and practical cars. Volkswagen Santana, Nissan Sylphy and Buick Hideo are all classic economical family cars. Is there no "doer" in the era of pure electricity? Here comes the new Weimar e.5.

The appearance is simple, but the body size is not mediocre.

Weimar E.5 is positioned as a medium-sized car, and the pre-sale price has not been released at present. The official said that its main competitors will be GAC Aion S and BYD Qin Plus EV, which also means that its price is likely to fall within 150,000 yuan. The design of Weimar E.5 is indeed a "clean stream" in the same class. The design of the whole vehicle is very simple, and with this white paint, it looks like a fat "white".

In the front part, Weimar E.5 continues the family design style, and the design of the upper and lower parts broadens the visual width. The upper part is connected with two headlights by a black decorative plate, and the middle car Logo is "dynamic logo", which can emit light alternately. When charging, each "vertical bar" lights up, which means it is full of 20%.

The far-near integrated headlights are relatively simple in shape, including turn signals and daytime running lights. The lower air intake grille is simple in shape, with slightly "moving" air intake decorative openings on both sides. On the whole, the front face of Weimar E.5 is simple and atmospheric, which is suitable for a wide range of age groups.

On the side, Weimar E.5′ s straight upper and lower waistlines also express its own simple theme, but the 18-inch rim has a good visual effect and exudes a sporty atmosphere. The real-shot model is equipped with the tire SU318A of Chaoyang, with the specification of 225/50 R18, which is a comfortable tire biased towards urban roads.

Weimar E.5, based on pure electric platform, is still relatively harmonious in side ratio, but you can see the black side skirt that is raised because the battery occupies the chassis. The suspended roof is one of the highlights of Weimar E.5, but there are not many such designs in cars, which also improves its recognition.

Weimar E.5 has a vehicle size of 4718x1838x1535mm and a wheelbase of 2810 mm. Therefore, in the face of compact cars with a wheelbase of 27XXmm such as Aion S and Qin Plus EV, Weimar E.5 is still very confident in space size.

In the rear part, the style presented by Weimar E.5 is also relatively stable and simple, but the shape of the taillight group is relatively sharp. In addition, the charging port of Weimar E.5 is placed on the left rear fender, which is convenient for charging when reversing into the warehouse.

Its trunk volume is 425L, and the depth is more than 1 meter. Among the 150,000-yuan cars, the volume is above the average level. Its trunk has a large opening, but the configuration is simple, only the lighting lamp, the electric tailgate, hook and net bag are not available, and there is no cover above the trunk for wrapping. Fortunately, it does not have much impact on daily use. There is no spare tire under the trunk floor, only triangular warning signs and tire patching agent are provided.

The cockpit is full of german flavor, and the car engine system is a big highlight.

The reason why Weimar E.5 is called "Santana" in pure electricity field is not only related to positioning, but also to its interior style. The cockpit of Weimar E.5 is as simple as its appearance, and it reveals a hint of Volkswagen. However, this simple and atmospheric style can really give people a good impression, and the cockpit materials of Weimar E.5 are also very solid.

In particular, the steering wheel feels delicate, the logic of multi-function buttons is clear, the intelligent driving assistance function is controlled on the left side, and the multimedia is controlled on the right side. Unfortunately, there are few control options for adjusting the contents of the dashboard. It is worth mentioning that although the steering wheel of Weimar E.5 only supports up-and-down adjustment, the position of the steering wheel is not too close to the center console, so we can feel that Weimar E.5 has made some efforts in ergonomics of sitting posture, because after I adjust my sitting posture, my hands and legs are in a more suitable state, and there are no shortcomings such as hand stretching or leg being squeezed, which are common in front driving. In addition, the floor-type "switch" used by Weimar E.5 is also helpful for comfort.

As an electric car, Weimar E.5 still expresses some technological elements, such as a 12.3-inch digital instrument screen and a 12.3-inch central control screen. The central control panel gives me a very good experience. Firstly, the system is smooth and the application program is opened very quickly. Secondly, the menu logic is clear. Finally, the application program completely meets the daily use. Weimar E.5 is equipped with the car version of Gaode map, with entertainment programs such as love listening and Tencent video, and can set Tencent video to continue playing while driving, which is bound to be good for the co-pilot, but it still needs the driver to regulate himself. The disadvantage is that the whole system does not provide the control and display interface of battery and electronic control, and maybe the subsequent OTA will solve it.

This system is also equipped with the brand-new Iflytek 3.5, which can control multimedia, air conditioners, windows, etc. The wake-up speed, recognition accuracy, recognition speed and execution speed are satisfactory, including the wake-up-free function.

Weimar E.5 keeps the traditional physical air conditioning control buttons and knobs, which is convenient for driving operation, but there is no relevant interface in the central control screen, and the buttons and knobs feel more general. In contrast, Weimar E.5′ s electronic knob handle, driving mode wheel and seat heating button feel much better.

Wide space and comfort are the biggest advantages of Weimar E.5.

At the level of 150,000 yuan, having the size of a medium-sized car is the biggest advantage of Weimar E.5. The wheelbase of 2810mm creates a "luxurious" rear row space for it, and the middle of the rear row is extremely small, which can basically be regarded as flat. With a height of 178cm, I can still have nearly 3 punches of leg space left in the back row, which is equal to Volkswagen Magotan.

The design of the two-section panoramic canopy adopted by Weimar E.5 is of great help to the lighting of the cockpit and the head space, with an area of 1.91㎡. The real shooting day is Shanghai in March, and the sun is shining at noon, so we can feel that its panoramic canopy has a great isolation effect on the solar heat. In addition, although the triangular window in the back row is small, it also contributes a lot to the sense of transparency.

In terms of seats, the real-shot models are made of leather+small-area fabric, which makes them feel delicate and pleasing. The front and rear seats are similar to the Volkswagen models. The cushions and backrests are moderately soft and hard. The driver and co-pilot also specially designed a small leg rest, which is hard to support the thighs. Weimar E.5 seats are excellent in wrapping and supporting performance in family cars.

The back seat of Weimar E.5 can’t be put down, which has a great influence on the convenience of loading. Fortunately, the comfortable back seat angle gives people great comfort. The rear water cup holder is folded and hidden under the air outlet of the rear air conditioner. This design is worthy of praise and easy to use! Most of the models are not equipped with rear handrails, so they will not be specially designed for you, but will directly cut off the cup holder.

Standard long battery life, no bluffing hard work.

According to the official news, the NEDC cruising range of Weimar E.5 will reach 505km, and its ternary lithium battery pack has a power consumption of 58.6kW·h and an energy density of 160wh/kg, which is considered as a good level at the level of 150,000. The three-in-one electric drive system used has the maximum power of 120kW, the maximum torque of 240N·m, the maximum speed of 170km/h and the acceleration time of 100 km of 8.9 seconds.

Weimar E.5 provides two charging methods, and it takes only 39 minutes for DC fast charging from 30% to 80%. It takes only 9.5 hours to charge the AC slowly from 0% to 100% in the State Grid.

summary

Without too many fancy designs, the new Weimar E.5 is a family car with clear functions. First, through the simple design inside and outside, to meet the likes of consumers of different ages; Second, the comfort advantage of 150,000 yuan is established through a long wheelbase. Coupled with ergonomic seats and panoramic awning, the comfort is really strong enough; The third is to meet the intelligent needs of users for today’s pure trams. This part is based on the experience of the car system and the program itself, which is not cool enough, but can be used in the heart. In terms of driving experience, Weimar E.5 is very likely to be comfortable, and with a battery life of 505km, home transportation is very suitable. How do you feel about such a medium-sized pure electric sedan? Welcome to leave a message below ~

CCTV News:This period of time coincides with the hot weather in the south, which is also the most suitable season for lotus growth in a year. In Xiangtan, Hunan Province, lotus pickers started the busiest time of the year in the heat and summer.

At 7 o’clock in the morning, the outdoor temperature has reached 32℃. This is the golden time for picking lotus. The lotus pickers put on rain pants and got into the lotus field with a height of more than one person. On the lotus field, the breeze is swaying the lotus leaf, but under the lotus leaf, it is completely airtight. The lotus pickers got into the lotus leaves as if they had entered a steamer. One person and one boat, they marched slowly in the lotus pond, tearing open the lotus leaf stalks densely covered with fields, and the lotus leaves with full grains bent came into view. The lotus pickers picked the lotus leaves and lotus stalks together.

Huang Fei, a lotus picker in Zhuojiang Village, Xiangtan County, Hunan Province:It will be preserved for a long time if there are (lotus) stalks. The key is that it can’t (pick the lotus) when it rains. The main reason for the rain is that the lotus seeds are broken. If you don’t wear long clothes and long sleeves, this lotus stalk will scratch people and make your hands burn like fire.

In the Xianglian Characteristic Industrial Park in Huashi Town, Xiangtan County, nearly 3,000 acres of lotus fields have also produced the first lotus seeds this year. At present, more than 30 nearby villagers pick lotus here every day, which can harvest more than 1000 kilograms of lotus. The villagers said that when there are the most people, more than 80 people will come here to pick, and they can pick tens of thousands of kilograms every day.

Liu Lizhi, a lotus picker in Zhonghua Village, Huashi Town, Xiangtan County, Hunan Province:A basket is about twenty-seven or eight pounds, because if it is too heavy, people will have deep mud in the field, which will be very hard to bear on people’s bodies (too much), so it is better for people to preserve their physical strength when walking. Generally, there are twelve or thirteen baskets a day. In the middle period, when there are many lotus seeds, one person can pick fifteen or sixteen baskets.

Every morning from 4 am to 9 am and from 3 pm to 7 pm are the busiest times for lotus pickers. These two periods are the times when lotus seeds have the most moisture and the best taste in a day. Under normal circumstances, the lotus began to mature in May of the lunar calendar and lasted until the end of August 15th of the lunar calendar.

　　The weather is getting hotter and hotter, and the epidemic situation has not completely ended. What kind of air conditioners may have the risk of transmission, and what precautions should be taken when using air conditioners? Recently, National Health Commission issued the Guidelines for Operation, Management and Use of Air Conditioning in Summer (Revised Edition), which is applicable to centralized air conditioning ventilation systems (including all-air air conditioning systems, fan-coil systems with fresh air, fan-coil systems without fresh air, and multi-connected systems) and split air conditioners in summer.

　　Preparation before opening of all-air air conditioning system

　　Grasp the source of fresh air and the scope of air supply, and strengthen personnel training;

　　Check whether the filters, surface coolers, heaters (humidifiers) and other equipment are operating normally. Clean and disinfect the open cooling tower and air handling unit, and clean the air duct when possible. Professional institutions are preferred to clean and disinfect the air conditioning system. When conditions permit, the sanitary quality of air supply should be tested, and the test results should conform to the Hygienic Management Standard for Central Air Conditioning and Ventilation Systems in Public Places (WS 394— 2012) and other national standards and specifications;

　　Keep the fresh air outlet and its surrounding environment clean, and the fresh air will not be polluted;

　　Keep a certain distance between the fresh air inlet and the exhaust outlet to avoid short circuit.

　　Management and maintenance in operation

　　Return air should be closed in medium and high risk areas. If the high-efficiency and above filter device is used in the air return port (pipeline) or air conditioning box, or an effective disinfection device is installed, the return air can be turned down;

　　It is suggested that the indoor temperature adjustment should not be lower than 26 degrees Celsius. If it can meet the demand of indoor temperature regulation, it is suggested that the doors and windows should not be completely closed when the air conditioner is running;

　　When using air conditioning system in crowded places, to strengthen indoor air flow, priority can be given to opening windows, opening doors or turning on ventilation devices such as fans, or air conditioning must be ventilated for 20 to 30 minutes every 2 to 3 hours;

　　For shopping malls, office buildings, underground garages and other places with large personnel flow, ventilation should be strengthened, and the fresh air and exhaust system of air conditioning system should continue to operate for a period of time after the business is over every day;

　　Strengthen the sanitary management of condensate water such as air handling units and fan coils and cooling water of cooling towers;

　　Regular cleaning, disinfection or replacement of filters, tuyeres, air handling units, surface coolers, heaters (humidifiers), condensate pans and other equipment and components of the operating air conditioning system;

　　U-shaped pipes such as sewer pipe, water seal of air handling device, floor drain of toilet and condensate drain pipe of air conditioning unit should be inspected regularly, and water should be replenished in time when there is water shortage.

　　Shutdown of air conditioning system

　　When confirmed cases and suspected cases are found in COVID-19, the following measures should be taken:

　　Immediately shut down the central air conditioning and ventilation system corresponding to the confirmed cases and suspected cases;

　　Under the guidance of the local disease control department, the central air conditioning and ventilation system in the above areas shall be disinfected and cleaned immediately, and can be re-used only after passing the hygienic inspection and evaluation;
