　　In recent years, the concept of suburban holiday leisure tour has been deepened, including but not limited to tent camping, beach barbecue, lawn frisbee and other light tourism projects. Along with this concept, SUVs with a hard-core style have gradually become popular.

　　As far as the new hard-core cars listed in the past year or two are concerned, there are no fewer than ten models, which shows the popularity of such sub-models. In my opinion, these hard-core style SUVs are on fire, but it is better to say that everyone’s mentality has changed. The pressure of employment and life in cities is great, and there is no better way to decompress in cities. With off-road vehicles, you can get closer to nature. For yourself, you have found a new way of life, so correspondingly, the demand for off-road vehicles has started to increase, and off-road vehicles have naturally become popular.

　　In addition, in the past, the SUV with hard-core style was either too expensive or uncomfortable to drive, but now the price of the model has become very close to the people and the comfort has been qualitatively improved. Today, the Jetway I test-drive is such a model, so what about the answer sheet it handed over?

　　In terms of appearance, Jetway Traveler, as its name implies, adopts the popular hard-core design and adds many outdoor elements to the details. And the most surprising thing is that the production model has highly restored the design of the previous T-X concept car, so the new car still looks very bright.

　　In the front face, the front of the car is tall and straight, and the front face is rich in layers. The blackened grille also integrates the ""brand logo that can be lit with the headlights, and the headlights on both sides adopt square elements. In addition, the front bumper and front and rear wheel eyebrows are equipped with LED light sources, and additional light sources can also be provided during travel or parking and camping.

　　The overall shape of the headlights is square, but the LED strip with longitudinal arrangement is adopted in the interior cavity, which not only creates a tough style, but also has strong scientific and technological attributes. This design is also the mainstream design of the current hard-core SUV, which is very pleasing.

　　Looking down again, you can see that the overall black bumper is very thick, and the tough lines have a little mecha design style. The details are also very rich. First of all, the trailer hook is common in hard-core models, but travelers paint it fluorescent, and in addition to fog lights, the bumper is also equipped with fill lights, which provide additional light sources in poor lighting conditions or camping.

　　Viewed from the side of the car body, Jietu Traveler adopts the square design used by many hard-core SUVs. The window frame is angular, and the large black wheel eyebrows protrude outward, which is very consistent with the positioning of the whole car. In the transition from C-pillar to D-pillar, the window line began to rise gradually, which increased the fashion sense of the side.

　　Jetway Traveler’s original factory is equipped with a very wide pedal, which is tough enough. However, for people who are taller, it is easy to get dirty without stepping on the pedal. If the pedal is slightly narrowed, the effect is expected to be better.

　　In addition, the front and rear rows are equipped with wide handles, which makes it more convenient for the elderly or children to get on and off.

　　In the details, the front and rear wheel eyebrows are also equipped with lights, and the roof rack is also decorated with fluorescent colors. In terms of body size, the new car is positioned as a medium-sized off-road SUV with a length, width and height of 4785×2006×1880mm and a wheelbase of 2800mm respectively.

　　In terms of rims, in order to cater to the hard-core modeling, the 19-inch blackened rims also adopt a thick multi-spoke style, and the details such as the hub cover are also painted in fluorescent color. And today’s test drive models are also equipped with Jiatong brand AT tires, which are 255/60 R19 in tyre size.

　　A large number of rounded rectangular design elements are also applied to the tail, and the outline is relatively rough. Above the tailgate, a small square schoolbag is hung with an external rear spare tire, which is also the standard configuration of the main hard-core style models.

　　At the same time, the vertical taillights are wrapped in a black frame and integrated with the black decoration on the upper part, showing a strong off-road temperament. The tailgate is also in the form of side opening. It is worth mentioning that the tailgate has a borderless design and looks more textured. Moreover, the tailgate also has an electric suction function, which is definitely a plus item.

　　The design of the rear bumper is consistent with the front of the car, and the shape is very strong. At the same time, the rear of the car also has LED fill light.

　　In the interior part, Jetway Traveler adopts the popular minimalist design style as a whole. The center console has a traditional T-shaped layout, but the interior looks more powerful through angular lines. At the same time, the four-spoke steering wheel with flat bottom up and down and the suspended large-size multimedia screen add a strong sense of science and technology to the interior.

　　In terms of materials, the car is also wrapped in soft and leather materials in a large area, and the interior color matching of the double fight looks fresher and more energetic. In addition, the square air conditioning air outlet, the handrails on both sides of the gear handle and the door handrails all create a sense of strength for the interior.

　　In addition, the decorative board in front of the co-pilot is composed of self-driving routes, which is more in line with the positioning of the model. This small detail is still very careful.

　　In terms of intelligent configuration, the screen size of the car is 15.6 inches, and 8155 chips are built in, so the response speed of the system is completely unnecessary to worry about. Moreover, the functions of the interior app application and intelligent voice control are also consistent with the mainstream models, and it is still very easy for young people to get started.

　　In other aspects, the new car is also equipped with 50W mobile phone wireless charging, fatigue driving reminder and other functions.

　　The shape of the electronic gear lever is very strong, which is very consistent with the positioning of its hard-core SUV, and the grip is also very comfortable, and the damping feeling of the lever is also very advanced.

　　Behind the handlebar are the shortcut buttons for driving mode, air conditioning A/C and panoramic image system, which is convenient for blind operation.

　　The chair is generous in shape, covered with suede material, delicate in touch and high in texture, and the letter LOGO "JT" is also marked on the back of the chair. Moreover, the fabric is soft and comfortable.

　　The rear seats are also spacious and comfortable, the rear backrest supports two angle adjustments, the central floor is also very flat, and it is equipped with air conditioning outlets and power interfaces. In terms of seating space, after the front seat is adjusted to the position of 1,9m adult male, the back seat will be an adult male with a height of 1.9m. The head and leg space still have more than one punch, and the space performance is excellent.

　　In terms of storage space, there are more than 50 storage spaces in the car, which are very rich. There are spacious storage spaces in front of the co-pilot, under the bumper and in the armrest box, which is very convenient for placing personal belongings.

　　In terms of trunk space, the overall volume is basically the same as that of the hard-core SUV of the same level, mainly because the lateral width is average, but the overall space is very regular, and after putting down the rear seats, it can form a very flat space, plus the shape of the generous box, which makes the storage space in the car very regular, and it is no problem to cope with daily family trips.

　　It is worth mentioning that the configuration of the trunk is very rich, with 12V cigarette lighter, 220V power supply, net bag and anchor point. Moreover, there are two hooks and two folding cup holders in the rear door, which are very practical for long-distance travel or camping in the suburbs.

　　In terms of power, the models of this test drive are all equipped with 2.0T Kunpeng power, the maximum power of the engine is 187kW, and the maximum torque is 390 Nm. In terms of transmission, it is matched with the 7DCT gearbox. In addition, Jetway Traveler also offers a 1.5T version to choose from.

　　This time, our main experience is its four-wheel drive performance. The 2.0T version of Jetway Traveler comes standard with Borgwarner’s sixth-generation four-wheel drive system, which can automatically switch four-wheel drive modes and intelligently distribute rear wheel torque. At the same time, it provides six driving modes: economy, standard, sports, snow, sediment and rock. It is worth mentioning that in addition to the above six driving modes, Jetway travelers also provide X mode, which can intelligently identify the road conditions, switch the corresponding modes, and always ensure the best driving state. In my opinion, this mode can be understood as a fool camera, and all the parameters are adjusted for you. Just click on it, which is a very practical function for off-road white. (And this cross-country experience is completed in X mode.)

　　In addition, Jietu travelers also have a approach angle of 28, a departure angle of 30, a minimum ground clearance of 220mm and a wading depth of 700 mm. For an SUV built with a load-bearing body, it can be said that the hardware is almost full.

　　In the actual experience, the four-wheel drive system can sense the tire idling in time and quickly lock the idle wheel, and the electronic slip-limiting intervention is also timely. It is no problem to get out of trouble in the face of the occasional challenges of the subject of experience, and it can also get out of trouble in time when the single rear wheel has adhesion. With the help of the car body data and the four-wheel drive system, its passability is indeed better than that of the general urban SUV.

　　During the 28 climbing experience, Jetway Traveler’s 2.0T engine has enough torque output, and it is easy to climb to the top of the hill with continuous and steady oil supply. Moreover, the AT tires equipped by the original factory did not slip too much during the constant climbing process, and the whole process was very easy. In addition, agile travelers also have the ability to cross a 45 slope.

　　It is worth mentioning that there is also a "cross-country dial" function in the car-machine interface. The left half can display functions such as compass, altitude, pitch angle, roll angle and wading radar, while there is a 3D model on the right, which can display tire pressure, tire temperature, front and rear power distribution, etc. The function is very comprehensive, and it is very playable and practical for hard-core positioning models.

　　The steering force is moderate, and it will be easy to get used to it. When passing on rough off-road roads, the steering will not flick. The gentle steering force is very easy for fine exercise and more controllable.

　　On the unpaved road section composed of gravel roads, the chassis of Jietu Traveler gave me a big surprise. On the high-frequency continuous vibration, the chassis inside the car felt very tight, and there was no unnecessary shaking. Moreover, after the vibration was resolved by the suspension and seat, it was not stiff to be transmitted into the car. In addition, there is no abnormal sound of any decorative parts in the car during high-frequency bumps, and the overall performance can be satisfactory.

　　With the timely four-wheel drive of Borgwarner, the system can accurately brake to lock the skidding wheels according to the road conditions. In the cross-axle test, it can be seen that Jietu travelers have a good suspension stroke, and the four wheels have no skidding phenomenon. As long as the throttle output is stabilized, they can easily pass.

　　When passing through the road surface composed of continuous tires, with strong torque output, Jietu travelers can also easily complete the challenge.

　　Although it is a load-bearing body, its body stiffness is greater than that of a general urban SUV, and its torsional stiffness reaches 31,000 nm/deg, which is enough to ensure that its body deformation is more controllable when facing road conditions such as cross shafts, so as not to make the car squeak. Moreover, it has a longer absorption time and more sufficient rebound absorption when experiencing some uneven roads, thus increasing the ability to get rid of difficulties.

　　In the actual experience, the four-wheel drive system can sense the tire idling in time and quickly lock the idle wheel, and the electronic slip-limiting intervention is also timely. It is no problem to get out of trouble in the face of the occasional challenges of the subject of experience, and it can also get out of trouble in time when the single rear wheel has adhesion. With the help of the car body data and the four-wheel drive system, its passability is indeed better than that of the general urban SUV.

　　From the actual experience, the passing ability of Jetway travelers is worthy of recognition, but I prefer to call it a light off-road vehicle, and this kind of vehicle will become more and more popular. Because in most families, most of them only have one car, so it is impossible to make a pure hard-core off-road vehicle+daily commuting model. Moreover, it is very rare for a large number of people to contact extreme cross-country The light off-road positioning car such as Jetway Traveler is a very balanced choice. The load-bearing car body can ensure enough comfort in daily commuting in the city, and the appearance of hard personality combined with good passing ability can also make you more comfortable and relaxed during the journey. Looking at the test price, it can be said that it is a new category of SUV within 150,000-200,000, which is worth a try for friends who like go on road trip.

　　[Pacific Auto] On April 28th, China Automobile Industry Association and National Computer Network Emergency Technology Processing Coordination Center issued the Notice on Testing Four Safety Requirements for Automobile Data Processing (the first batch), and all the models produced by Shanghai Superfactory met the compliance requirements. It is expected that all localities will lift the prohibition and parking restrictions on peer-to-peer intelligent networked vehicles (such as government agencies, airports, highways, etc.).

　　According to the public notice, Tesla, as one of the first enterprises to pass the national authoritative vehicle data testing, carried out the vehicle testing in strict accordance with the relevant laws, standards and testing procedures, and met the four compliance requirements of the national regulations and standards, such as Several Provisions on the Safety Management of Vehicle Data and GB/T 41871-2022 Safety Requirements for Information Security Technology in Vehicle Data Processing: anonymous processing of external face information, default not to collect cockpit data, and in-vehicle processing of cockpit data.

　　In addition, many brands and models, including,,, Nezha and so on, also successfully passed the data security compliance test. It is reported that this test follows the principle of voluntary inspection by enterprises and evaluates the data security compliance of newly listed intelligent networked vehicles in 2022-2023.

　　At present, new energy vehicles can collect a large number of diversified vehicle data by equipped with advanced sensors and intelligent systems. However, this technological progress has also brought new challenges to data security. Tesla has been concerned about data security issues before, and even restricted in some places. The announcement of the test results not only provides an official endorsement for the data security of many new energy vehicles such as Tesla, but also sets a new standard for data security for the whole industry. This progress is expected to promote the wider application of intelligent networked vehicles and strengthen consumers’ trust in new energy vehicle technology.

　　It is worth mentioning that the core reason why Tesla’s FSD fully automatic driving software can’t be pushed in the mainland market is data security, and this time, the national authoritative data security test has laid a certain foundation for Tesla to promote FSD to enter the China market.

　　However, despite Tesla’s deep technical accumulation in the field of intelligent driving, the competition in the domestic market is also extremely fierce. Domestic car companies have made rapid progress in the field of advanced assisted driving, and many car companies provide advanced intelligent driving functions for free. In this case, the optional cost of Tesla FSD fully autonomous driving software is as high as 64,000, which is undoubtedly a big burden for consumers. If the price cannot be reduced, even if it comes into the domestic market later, it will be difficult to obtain wide acceptance because of the high use cost.

　　In addition, the road and traffic environment in China may be different from that in the United States, and Tesla may need to localize and optimize the FSD to meet the actual needs of the domestic market. Are you optimistic about Tesla FSD entering the domestic market? (Text: Pacific Auto Wu Qi)

　　The reporter learned from the press office of Guanshanhu District People’s Government that after more than ten hours’ efforts, as of 3 am on October 29th, all 10 trapped people had been found, including 8 deaths and 2 injuries. At present, the local emergency rescue headquarters is carrying out the work of treating the injured and comforting the families of the victims, and investigating the cause of the accident.

　　Two injured people were treated by surgery in the hospital.

　　After the accident, two injured people underwent surgery in the nearby Jinyang Hospital to see the report sent back by the reporter from the hospital.

　　At 0: 30 on October 29th, the reporter rushed to Jinyang Hospital in Guiyang and found the doctor Liu Hui who had been leading the team for treatment.

　　Liu Hui, Chief of Medical Department of Guiyang Jinyang Hospital: Two wounded. We have four groups now. Cardiothoracic surgery, orthopedics, ICU and operating room are all here, so we have four groups of people to rescue two patients.

　　Dr. Liu told the reporter that the two injured people had multiple fractures all over their bodies.

　　Liu Hui, Chief of Medical Department of Guiyang Jinyang HospitalOne of these two is a fracture of pelvis, and then there is a fracture of many upturned bones, one is a damage to the left hand, two fractures of the nasal bones, one is a head injury, and the other is a avulsion injury, so we went to many doctors to rescue them here. Reporter: but there is no danger to life, right? It’s hard to say at present.

　　The press conference will continue to pay attention to the treatment of the injured.

Analysis of product characteristics;Silicone oil fan engine produced in 2021!

　　On the new generation LC300, Toyota has prepared three powertrains for it, all of which use silicone oil fans as the cooling scheme. ! This may be the only mass-produced new car with silicone oil fan in the 21st century! You know, even the brand-new fourth-generation Jimny gave up the silicone oil fan …

　　Two newly developed V6 twin-turbo engines (3.5L gasoline and 3.3L diesel) based on TNGA platform can surpass the traditional V8 engine in performance. The 3.5T V6 version of gasoline (code V35A-FTS) has a power of 415 HP, a torque of 650 Nm, and an acceleration of 0-100km/h of 6.7 seconds! (Another Mammoth) The other is a diesel 3.3T V6 engine (code F33A-FTV) with a maximum power of 309 HP and a torque of 700 Nm. Both power systems will be equipped with 10AT automatic transmission.

　　In addition, in some areas with low emission requirements.(Say goodbye to us completely)LC300 continues to provide the 1GR-FE 4.0L V6 engine that is "classic and super-resistant and not picky about food", with a maximum power of 275 HP and a maximum torque of 385 nm, matching the 6AT gearbox.

Tips: silicone oil fan

　　In fact, many people are very, very unfamiliar with silicone oil fan, because it really only appears on some traditional and old-fashioned off-road vehicles. Unlike today’s electronic fans, it doesn’t have so many sensors, and it can’t adjust and open the fan in time according to the water temperature. It is more primitive! It determines whether to enter the working state and stage according to the characteristics of engine speed.Generally speaking, it belongs to the type of "turning more and more", just like the red-headed machine adopted by Honda S2000, but you can’t always turn up the speed to get cool instead of commuting, can you?The silicone oil fan is similar. In congested cities and some low-speed environments, its heat dissipation performance is difficult to guarantee, but it can provide strong heat dissipation performance and high reliability in some high-speed crossing environments or desert environments.

　　Many people think that the silicone oil cooling fan is a product of the last century, and it is rarely used in gasoline engines now, and it is hard to see it in today’s new generation of hardliners. It originally belongs to a mechanical temperature control fan, powered by the crankshaft pulley of the engine, and driven by a belt to rotate the silicone oil cooling fan. When it is started, it can hear a loud noise. It is this silicone oil fan that makes people look askance, as if it is a large displacement. The off-road vehicle uses a silicone oil fan, but the focus is on its reliability.

Analysis of product characteristics;Introducing transparent chassis /MTS all-terrain system

　　Transparent chassis is nothing new. From the propaganda of Land Rover in the early days, people can understand the concept of transparent chassis. Through the intervention of cameras, vehicles can have more observation dimensions when traveling off-road. Through the screen, we can get the road conditions in real time, which can play a great auxiliary role in judging the route and avoiding danger. The familiar Toyota MTS all-terrain system can automatically choose the best driving mode according to the transmission of road conditions.Adaptive Variable Suspension (AVS) can calmly face all kinds of complicated road conditions.The all-terrain selection system also adds Zita Law and automatic mode,The crawling system has also been re-optimized, and the speed can be controlled in the off-road process. Combined with the transparent chassis, the land patrol LC300 has realized the intelligent off-road experience in line with the current mainstream trend.

Analysis of product characteristics;Welding technology of non-load-bearing body/brand-new frame

　　From the chief engineer’s mouth, we can see that they have a lot of pride in the land patrol with TNGA-F platform. The land patrol LC300 is the first mass-produced vehicle with non-load-bearing body under TNGA framework, and its frame has undergone a brand-new welding process, and a lot of weight reduction work has been done on the premise of ensuring strength. The welding of the body frame is no longer connected by traditional overlapping welding, but is approximately "seamless fusion" on a plane.

　　In addition, in order to change the heavy front of the previous generation Land Patrol, the engineer adjusted the position of its engine gearbox, and the height dropped by 28mm, while the whole body moved back by 70mm, and the front and rear weight reached 53.5:46.5, which is undoubtedly a very positive and important change for a large hard-core SUV model. The change of center of gravity and overall weight will greatly affect its driving performance in various road conditions.

Analysis of product characteristics;E-KDSS system/second generation TSS system

　　What is KDSS?KDSS is not magical, but it is indeed a unique martial art of Toyota. It is a hydraulic self-adaptive adjustable balance bar system, which can be regarded as a kind of active suspension. The sensor will predict your driving environment and road conditions according to a series of dimensions such as vehicle speed and left and right compression of the car body, and adjust the hardness of the balance bar in real time, thus affecting the car body roll and suspension stroke.

　　Once the system senses that the vehicle speed is high, the KDSS hydraulic shock absorber will become hard, and the support of the original vehicle suspension will be improved by changing the hardness of the balance bar. If you feel that the vehicle speed is low, for example, if you cross the road and the left and right wheels expand and contract, the pressure difference of KDSS oil shock absorber will become softer, and it will be easier to release the stroke, so that the four wheels can touch the ground as much as possible, increase the friction and reduce the appearance of cross shafts.

　　But in fact, for those professional players who really use land patrol to play cross-country, the biggest drawback of KDSS is that it affects the vehicle’s elevation. If the elevation does not exceed 2 inches, the operating range of KDSS will be stretched to the limit, and then it will fail. The alarm light will always be on, and the after-sales maintenance and replacement cost of KDSS is not low, just tens of thousands of pieces. Even if you want to tear it down, you need a series of matching and re-purchasing new balance bars, and the price is also very expensive. so~ Unless you are a targeted professional group, there is absolutely no need to have too many ideas about KDSS. It is a way to have both, not to pursue the extreme in a certain direction, and it is enough for most people.

　　On the new generation of land patrol LC300, this system has become an electric control system. Obviously, its sensitivity, response speed and accuracy will be significantly improved, and its sensitivity to road changes will be better, which is worth looking forward to.

　　The land patrol LC300 is also equipped with the second generation Toyota Safety Sense, which enables it to have better safety early warning performance in urban environment and pavement environment.Compared with the previous pre-collision system, two new functions have been added;Help avoid collisions or reduce injuries by detecting pedestrians and cyclists during the day and night.

　　The first realization scenario is to detect oncoming vehicles and pedestrians crossing the road when the vehicles turn in any direction. The second realization scenario is: the active lane keeping and collision prevention system is not sophisticated, but for a hard-core model with classic heritage, the increase of these auxiliary configurations will undoubtedly make it have better active safety performance in paving environment and highway. In addition, the land patrol LC300 is also equipped with a parking assistance system, which can identify obstacles or pedestrians in the rear during parking, which is very necessary for "it is so huge".

Analysis of product characteristics;Driving assistance/comfort adaptation

　　In addition to the above parts, the land patrol LC300 has been improved in many details, such as changing the inclination angle of the shock absorber again. After being tested and adjusted by Dakar drivers,Combined with these changes and optimizations, the new model will have more comfortable and faster steering performance and handling, and its directivity and vibration filtering performance will also be improved.In terms of comfort in the car, the land patrol LC300 also has pursuits, such as; With the adjustment of the seat position, the steering wheel will also be adjusted to bring more comfortable driving experience and reduce the driver’s fatigue.

　　On the brand-new land patrol LC300, NVH performance is highlighted. Take the 3.3T diesel as an example. Even when driving fast in a non-paved environment, people in the front and rear rows of the car can easily talk at a normal volume. Just as Toyota said, they hope that this car can not only take you anywhere, but also drive and use it more easily in a paved environment, and minimize fatigue.

Editor’s Summary: Inheriting the Initial Heart & Trying to Break the Circle

　　TNGA-F, non-load-bearing, new welding technology, silicone oil fan … These actions are not just about paying tribute to classics or selling feelings. I believe Toyota is well aware of the significance of land cruisers to Toyota brands. It can be seen that Toyota has tried its best to retain the characteristics and soul of land cruisers in research and development, so that it can continue to gallop anywhere in the world.

　　The blessings such as E-KDSS, MTS and TSS make it more in line with the comprehensive needs of the new era. Even if you are a tough guy, you will not forget your tenderness. Let more people have and like it is something Toyota must do, not just land patrol, but what every "off-road vehicle" wants to do and is doing today. After all, who doesn’t want it to be sold to more and wider people? Look at Big G, look at herdsman, look at Tank 300 … Which one doesn’t think so?

　　Next, let’s have a static real car. Although we really don’t know the exact situation of the version of the Bank of China and parallel imports at present, I suggest you can look forward to it. (Text/car home Ren Bo)

　　Nanhu Lake in Jiaxing, Zhejiang, is full of tourists every day.

　　On the island in the middle of the lake, a red boat lies still on the water, restoring the historical scene of the Communist Party of China (CPC)’s birth. Not far away, it is the magnificent new South Lake Revolutionary Memorial Hall.

　　Here, watching an exhibition, listening to a party class, learning about party constitution, watching a feature film, paying tribute to a red boat and revisiting the pledge of joining the Party can make the spirit inherit and the thoughts sublimate.

　　South Lake in Jiaxing is the birthplace of the Communist Party of China (CPC).

　　In order to effectively protect and manage the site of South Lake, the Nanhu Revolutionary Memorial Hall in Jiaxing was established in 1959. After more than 50 years of construction and development, Nanhu Revolutionary Memorial Hall has become a patriotic and party history education base with high popularity and influence in China, receiving more than 1 million visitors every year.

　　Nanhu Revolutionary Memorial Hall records the revolutionary history and inherits the "Red Boat Spirit". However, the old memorial hall is limited by space, which affects the visiting effect.

　　In February 2005, the staff reported to the supreme leader comrade who made a special trip to Jiaxing Nanhu to pay tribute to the red boat, and he was planning to expand the memorial hall or open a new site. Comrade Supreme Leader expressed his support on the spot.

　　According to the "2004— Outline of the National Red Tourism Development Plan in 2010, and in 2005, the expansion plan of the new Nanhu Revolutionary Memorial Hall was formulated.

　　In October of the same year, the expansion plan was approved by the General Office of the Central Committee of the CPC and Publicity Department of the Communist Party of China, and the National Development and Reform Commission formally established the project, which was included in the investment plan of funds (government bonds) in the national budget for infrastructure projects of red tourist attractions that year.

　　On June 28th, 2006, on the occasion of the 85th anniversary of the founding of the Party, with the care and support of the Supreme Leader, the new Nanhu Revolutionary Memorial Hall broke ground. On March 5, 2007, the expansion project of the new museum officially started construction. By the end of 2008, the main project of the new building was basically completed. On June 30th, 2011, on the occasion of the 90th anniversary of the founding of the Party, the new Nanhu Revolutionary Memorial Hall, which took five years to build, was officially opened to the public.

　　The new Nanhu Revolutionary Memorial Hall, which is located on the bank of the scenic South Lake, is located in the central plot south of Nanxi Road, north of Yuanhu Road, east of Huayuan Road and west of Haiyan Tang Road parking lot in Jiaxing City. It covers an area of 2.73 hectares and consists of three buildings: one main building and two auxiliary buildings.

　　The new building has a total construction area of 19,633 square meters, including an exhibition hall area of 7,794 square meters. The main building of the new building has one basement and three floors above ground, with a construction area of 10,435 square meters, including an exhibition hall area of 5,167 square meters. The East and West Annex Buildings are two-story buildings with a building area of 9,198 square meters, with an auxiliary exhibition hall, an academic lecture hall and a service area, of which the exhibition hall covers an area of 2,627 square meters.

　　The new building with solemn architectural style has an "I" shape, which represents that the Communist Party of China (CPC) is a political party of the working class. There are 56 eaves columns around the building, which means that 56 ethnic groups of the Chinese family are closely United around the party. The exterior wall of the building adopts large-scale blue brick, which makes the whole building not only reflect the solemn and atmospheric style, but also show the charm of Jiangnan water town. To the south of the new building is July 1st Square, and to the north is the oath platform.

　　First-class architecture, first-class content, first-class exhibition.

　　After the new museum was completed and opened, it not only became the new coordinate of Jiaxing’s urban construction with its solemn and atmospheric architectural style, but also was highly praised and fully affirmed by all walks of life and the vast audience because of its informative and vivid exhibition content and brand-new exhibition form.

　　The memorial hall, which has no closing day for 365 days a year, welcomes thousands of people from all over party member every day. There was a long queue at the entrance of the memorial hall, and many people wore party emblem on their chests.

　　Lu Huiwen from Shanghai is an old party member who has been a party member for 47 years. A group of 30 of them revisited the oath of joining the party in front of the oath wall of the memorial hall. He said that every time he came to Jiaxing, he would visit the Nanhu Revolutionary Memorial Hall or pay tribute to the Red Boat. This was the fifth time.

　　"Although I have retired, I always remember that I am a Communist party member, and I will try my best to perform my duties as a party member every day of my life." Lu Huiwen, whose temples are white, still said with passion.

　　Time flies in 1996, and the vicissitudes of 1996 have changed dramatically. From 1921 to 2017, from 58 party member to more than 80 million party member, the Communist Party of China (CPC) led the ship of China’s revolution, construction and reform all the way, braving the wind and waves and courageously moving forward.

　　"After the completion of the new building, it has been widely praised by the outside world. It is believed that the architectural style and scale of the new building have well interpreted the important historical position of Nanhu as the birthplace of the party." Zhang Xianyi, director of the Nanhu Revolutionary Memorial Hall, said, "The memorial hall is like a heavy book on the history of the Communist Party of China (CPC)’s party, which left a deep impression on everyone."

　　During the National Day holiday this year, the Nanhu Revolutionary Memorial Hall received 50,000 visitors. "Since the opening of the new museum, the annual reception volume has been around 1 million." Li Yun, deputy director of the Nanhu Revolutionary Memorial Hall, said that the memorial hall has given full play to the role of base education, and has successively formed co-construction relations with more than 40 schools and units, regularly or irregularly carried out co-construction activities, held various lectures, developed and expanded the volunteer team, and actively cooperated with the holding of adult ceremonies, party swearing-in ceremonies and various theme activities, with increasing social influence.

　　(Jiaxing, Zhejiang, November 2 nd, our reporter Yan Hongfeng, our correspondent Pan Xingmei)

　　The skull of the cave bear discovered by the researchers is much larger than that of the existing brown bear. Image source: Science Progress website

　　Most people may have heard of the extinction of mammoth mammoth, hairy rhinoceros, bighorn deer and other giant fauna in Eurasia during the thrilling extinction event of the Ice Age, but they are not necessarily familiar with cave bears with a body width of 1.7 meters, a body length of 3.5 meters and a weight of more than one ton.

　　Ursus spelaeus is a kind of bear that lived in the northern part of Eurasia in Pleistocene. It became extinct about 20,000 years ago. Because its fossils were mostly found in caves, it was named "Cave Bear". In many famous caves, almost all the bones of the cave bear have been found. It was also found in Zhoukoudian, Beijing, China, and it was the two giant bears in the Pleistocene with the giant short-faced bear.

　　Whether the cave bear is a vegetarian or a carnivore, and what is the relationship between the "recipe" of this behemoth and its extinction, the scientific community has always had different opinions. In recent 40 years, through the research on the level of nitrogen -15 in the bones of cave bears, some scientists think that they are herbivores because they like tender grass, grass roots and strawberries. Some scientists believe that they also hunted some animals, even humans at that time, which should be carnivores. Recently, a famous international journal, Scientific Progress, published a paper saying that scientists gave a biomechanical explanation to the eating habits of cave bears through computer simulation, and put forward a brand-new view that "chewing leads to the functional degradation of sinus and other systems, and then the skull becomes smaller, which may lead to the extinction of cave bears" through the relationship between chewing exercise and skull development.

　　Viewpoint 1: Plants wither and starve to death due to falling temperature.

　　Three years ago, Yukichi Naito of the University of Tubingen, Germany, found that the content of nitrogen -15 in the bones of cave bears was low, with strong jaws and large flat teeth, and only dense vegetation grew around their residence. All this shows that cave bears are herbivores. This special diet is the reason why the cave bear became extinct more than 20,000 years ago.

　　At that time, the temperature dropped sharply, and the vegetation withered in a large area, which made the cave bear lose its food. Scholars believe that because the food of the cave bear is very single, it must eat a lot in order to meet the needs of the body. Compared with pandas who have to eat 40 kilograms of bamboo every day, cave bears eat more than that, and the nutrient conversion rate is very low. On the contrary, the brown bear is an omnivore with high nitrogen content in its bones. Its diet includes fruits, honey, fish and so on. Its rich diet structure makes it more adaptable to the environment, so it can be widely distributed. This view has also been widely recognized.

　　The second point of view is that the fight between caves and humans has been wiped out.

　　In the Carpathian Mountains in central Europe, the bones of cave bears discovered by scientists show that cave bears are not as gentle as people thought before. They have huge teeth and razor-sharp claws, are fierce carnivores and even eat people. By analyzing the data of cave bear bones found in the southwest corner of this mountain range in recent years, scientists show that most cave bears have a lot of nitrogen -15 content, which exceeds that of many herbivores. This shows that these cave bears are carnivorous individuals and are typical carnivores. They not only compete with humans for caves, but also prey on hyenas, gray wolves, cave lions and fish.

　　In December 2019, Science Report magazine published an evolutionary research report by European scientists, saying that the cave bear population began to decrease sharply about 40,000 years ago, which was earlier than the climate cooling period and coincided with the spread of modern humans in Europe. The cold climate and the subsequent reduction of plant-derived food may lead to the dispersion of cave bear population into different sub-populations, which live in small habitats with mild climate and rich plants. Various human behaviors, including hunting, may have interrupted the connection between these sub-populations, thus playing a decisive role in the extinction of cave bears.

　　This view has already appeared in the Journal of the National Academy of Sciences in 2008, and an international research group composed of scientists from the United States, Britain and Germany published their findings — — The cave bear is one of the strongest rivals of human ancestors. With wisdom, human ancestors destroyed the living environment of these fierce animals, drove them out of their caves and rushed to the mountains. There is evidence that some caves were occupied by ancient humans and cave bears alternately. From this, it is speculated that humans killed or drove away those depressed bears during the hibernation of cave bears; When spring comes, the cave bears who are awake from hibernation and hungry in their bellies will attack humans and recapture the caves. In this cycle of fighting, humans with slightly stronger intelligence finally seized the caves and wiped them out.

　　The latest view is that chewing ability becomes weak, so you can’t eat meat and "sleep for a long time"

　　French and Belgian researchers found that the cave bear is an omnivore by analyzing its teeth. Compared with herbivores, carnivores will accumulate more nitrogen in the body during eating. In addition, black bears and brown bears are omnivores, which shows that although cave bears may mainly eat grass in most cases, sometimes they will taste the meat.

　　Axel Barlow of Potsdam University in Germany and others have analyzed the genome sequences of four cave bears that lived between 71,000 and 34,000 years ago, compared them with those of other animals, and analyzed the scratches and spots on their tooth glazes to judge their food composition. The researchers introduced in the Proceedings of the National Academy of Sciences that they found that cave bears were not vegetarian. Before entering hibernation, cave bears had a variety of foods, including poultry and mammals, invertebrates, seeds and various dried fruits and fresh fruits. Like most omnivores, it will not go into hibernation until it stores enough energy.

　　According to the latest viewpoint published in Scientific Progress, the extinction of the cave bear is not due to the competition with human beings, but because the cave bear’s nose has evolved a special structure. The research team from the University of Malaga, Spain, analyzed the eating scene of cave bears by computer simulation to determine whether cave bears can effectively adjust their diet under the condition of limited vegetation resources, thus explaining why European cave bears became extinct during the climate change period.

　　The research team scanned the skulls of four cave bears and eight living brown bears, and found that the sinus of cave bears was surprisingly large, and the sinus directly affected the chewing mode, strength and amplitude. Due to the enlargement of the sinus, the skull and cranium of the cave bear face are deformed, and the originally round top of the head becomes flat and extends backward continuously, so the bite force of the canine teeth and incisors becomes weak. As time goes by, they can’t tear the meat with their front teeth and canine teeth, but only rely on molars to grind the plants and swallow them. Therefore, when grass is not enough to eat, they can’t turn to meat.

　　Why did cave bears evolve into large sinuses? In the cold ice age, cave bears hibernate longer than other Xiong Ke animals in a year, and the large sinuses help to reduce the consumption during hibernation. Sinus is a cavity in the skull, with four pairs, which are symmetrical left and right. It can adjust the temperature and humidity of the air inhaled into nasal cavity, which is very important for cave bears to hibernate.

　　Alejandro perez Ramos, a paleontologist at the University of Malaga in Spain, one of the authors of the paper, explained that cave bears evolved large sinuses to adapt to the environment. With large sinuses, they can reduce energy consumption by hibernating in winter, so as to survive the winter when food supply is insufficient. But it is also because of the large sinuses that their chewing ability is affected. They can only eat grass and can’t eat meat at all. When the vegetation can’t grow because of the cold, the cave bear can’t survive by changing its diet, especially before hibernation, because it fails to intake enough energy, it is likely to run out of fat and "stay awake for a long time", which eventually leads to the extinction of the whole species.

　　Of course, more research evidence is needed about the sinus structure of cave bear. It is believed that with more and more scientific discoveries mastered by scientists, whether cave bears are vegetarians or omnivores and the mystery of cave bears’ extinction will eventually be revealed to the world.
