Oh, my friends, today I’m going to introduce you to a good car that smells really good!

No, Audi has recently made a big move to directly reduce the price of their flagship model A8 by 1.18 million!

No mistake, it is 1.18 million!

This operation is simply "superior"!

You know, A8 is the top luxury car of Audi’s family, and it usually exists high above it.

This time, there was a direct "popularization". Su Ge, I can’t help but say: Audi, are you taking the wrong medicine?

Seriously, such a big price cut makes me have to "stand up" and talk about this car. Let’s start nagging from the appearance!

The design of A8 is really a "sharp weapon"..

The domineering hexagonal air intake grille with sharp LED headlights is simply a mobile "light factory"!

When you drive out at night, you must pay more attention to passers-by.

The lines on the side of the car body are smooth and elegant, and the penetrating taillights at the rear are the finishing touch.

This face value will definitely make you look for a car in the parking lot!

Let’s talk about the interior, my friends, this is really a "top-notch" enjoyment.Full LCD instrument panel plus dual-screen central controlThe sense of technology is bursting!

The seat is made of top-grade leather, so comfortable that you don’t want to get down.

The back row can still lie flat, which is simply a moving "bed car".

If you like a quick trip, this car will definitely satisfy you.

What excites me most is its power system.3.0TV6 engine plus 8-speed automatic manual transmission, coupled with quattro four-wheel drive system.This combination is simply synonymous with "driving toys"!

The power output is smooth and strong, and the "100-kilometer acceleration" takes only 5.6 seconds, so overtaking should not be too easy.

If you like driving fast, this A8 can definitely satisfy your desire for speed.

Of course, good cars have to be compared.

At the same level, there are Mercedes-Benz S-Class and BMW 7 Series.

S-class interior is more luxurious, but the price is higher; The control of the 7 series is more sporty, but less comfortable.

By contrast,A8 has found a good balance between luxury and sportiness.Coupled with the sharp price reduction this time, the cost performance can be said to be quite high.

Speaking of which, I think it is necessary to remind everyone:Don’t get carried away by this price reduction..

Although the price has dropped, the cost of maintenance is not cheap.

After all, this is a top luxury car, and the price of parts and maintenance costs are not easily borne by ordinary people.

Therefore, you still have to weigh your economic strength before buying a car.

The price reduction of Audi A8 this time is really full of sincerity. There is nothing to say about luxury, science and technology, and dynamic performance. Now the price is more close to the people, which is simply a perfect interpretation of the law of "true fragrance". But then again, buying a car of this level can’t be done just by looking at the price, but also by considering the subsequent use cost.

Ok, that’s all for today’s car review. Friends,Do you think the Audi A8 with such a sharp price cut smells good?If you have this budget, will you consider starting? Welcome to talk to me about your thoughts in the comments section!

1905 movie network news On June 16th, the film held an advance viewing ceremony in Shanghai. Director, screenwriter and starring with actors,,, debut.

The directors, actors, producers who have cooperated with Wang Baoqiang, the Olympic champion and son Zou Mingxuan who cooperated and participated in the variety show all came to the scene to support them, which made the scene set off a wave of "memory killings in the same box".

Coincidentally, it happened to be Wang Baoqiang’s Lunar Birthday, and the audience and friends also collectively sang birthday songs and offered their blessings to him.

Speaking of the six-year creative process, director Wang Baoqiang was filled with emotion. "This is a work with realistic theme, and it also contains the theme I want to express in recent years. Everything I want to say is in the movie." Chen Yongsheng, a former actor, is very grateful to director Wang Baoqiang for giving him the opportunity to break through the image. Shi Pengyuan admits that he was very nervous when he joined the group on the first day, but the director has been very patient and caring for him, which has made him gain a lot.

Chen Sicheng, the director of Wang Baoqiang’s "detective chinatown" series, witnessed the creation of "In the Octagonal Cage" and was one of the first people to see the film. "I didn’t expect Baoqiang to choose this theme, and the degree of completion was so high. Everyone has an octagonal cage in his heart and wants to break free. I hope this film will bring the audience and China movies out of the octagonal cage."

Actor Haoran Liu also lamented the contrast of "Uncle" Bao Qiang. "I was the most familiar person with Bao Qiang. I saw him in this movie as a stranger, and the actors’ performance was so good!" On the occasion of the reunion of the crew, the founders also put words on the spot: "Tang Detective 4" doesn’t have to wait for six years!

Director Xu Zheng recalled the wonderful time when he celebrated Wang Baoqiang’s birthday in the "Thailand" crew more than 10 years ago. "Time flies so fast. This time, Baoqiang re-directed the tube, and there must be a unique trick. When I saw the trailer, I felt that this texture would definitely be’ successful’!"

Zou Shiming, the Olympic boxing champion, affirmed "The Octagonal Cage" from a professional point of view. "The technical movements in the movie are very professional, and it also shows that the children in the mountains are not afraid of suffering and suffering, and they want to change their destiny with their fists."

Elimination method of Kaiyi Xuanjie maintenance lamp

To eliminate the maintenance lights of Kaiyi Dazzle, you can follow the following steps:

1. Turn off the power: press and hold the OK key on the steering wheel, and press the start key twice in succession, but don’t strike a light.

2. Maintenance to zero: After completing the above steps, wait for 3-5 seconds and then release the OK key. The maintenance light will disappear, indicating that the maintenance zeroing is completed.

The above is a simple way to eliminate the maintenance lights of Kaiyi Xuanjie. After the maintenance light is on, it must be maintained in time to ensure the normal operation of the vehicle. Maintenance can prolong the service life of vehicles, improve driving safety, and ensure the performance and appearance of vehicles. It is recommended to carry out maintenance according to the maintenance cycle specified in the vehicle maintenance manual to ensure the best condition of the vehicle. If you are not sure about the maintenance cycle, you can consult an automobile maintenance expert or the staff of a 4S shop.

　　Core reading

　　The pseudo base station is called by everyone, but how can it show its original shape? Guangdong Mobile uses big data to deploy tight encirclement. According to the cell phone signal data, timely warning; End, tube and cloud data linkage to accurately identify pseudo base station short messages; Cooperate with the police to locate the attack. The data shows that the activity of pseudo base stations has dropped significantly.

　　"Dear users, hello. You get the discount of sending 50 yuan to 100 yuan. Click wap.××××××.com to recharge, which is limited to this machine. China Mobile. " Seeing this message from "10086", Zhang Xuewei hesitated and felt that the recharge website was suspicious. Fortunately, another early warning message from China Mobile came immediately, reminding him that he might have been attacked by a pseudo base station just now.

　　As a common tool of criminals, the harm of pseudo base stations has attracted the attention of the whole society. If you impersonate a bank to send a short message with a virus link, once the user clicks on the link, it will lead to cell phone poisoning, privacy information being stolen, and then property losses will be caused.

　　Zhang Xuewei is located in Foshan, Guangdong Province. This time, he accepted the free early warning service of pseudo base stations independently developed by Guangdong Mobile based on big data. The service was piloted in Foshan, Jieyang and Chaozhou at the beginning of November last year, and so far more than 600,000 users have been reminded.

　　Use signal data to see through pseudo base stations and give early warning in time.

　　Normal base station: "Where does your signal come from?"

　　Mobile phone: "I came from a base station."

　　Normal base station: "No, I don’t even know this guy. It’s definitely not ours ‘ Little friend ’ ！”

　　The normal base station keenly found that the mobile phone had been held by a pseudo base station, so it reported it to the network system.

　　When Zhang Xuewei received the fraudulent short message, the above "conversation" started between the normal base station and his mobile phone.

　　Pseudo base station is an illegal device that does not access the operator’s network. It can simulate any number to send illegal short messages. "It’s a base station, but there are actually two small boxes." Along the direction of Liu Shaocong’s finger in Guangdong Mobile Wireless Optimization Center, two "iron boxes" are lying on the table, one is smaller than the computer case, and the other is only the size of a shoe box.

　　At present, the pseudo base station technology and price threshold are very low. Moreover, as the volume shrinks, the forms of crime are more diverse: some throw pseudo base stations next to roadside garbage bins; Some put it in their backpacks and get on the bus to move and signal; And hire someone else to carry it, hide in the dark and send it remotely with a mobile phone … …

　　However, "no matter how cunning a fox is, it can’t fool a good hunter." Pseudo-base stations switch mobile phone signals with stronger power, which also becomes a breakthrough for technicians to detect pseudo-base stations. Simply put, when a mobile phone that has been held hostage by a pseudo base station signal is reconnected to the normal base station network, it will bring the relevant signal data of the pseudo base station.

　　"At this time, big data will come in handy." Liu Shaocong said that the abnormal signaling found by the normal base station will be uploaded to the network and compared with a large number of normal signaling, and finally it is determined that this unknown guy is a "bad guy." Then, an early warning message will be sent to the user’s mobile phone.

　　End, pipe and cloud data linkage, accurate identification

　　Pseudo base stations can change their numbers at will. In a bunch of normal short messages, how can we find out the fraudulent information at once?

　　Xu Jiajun, who works in Guangdong Mobile Network Management Center, took out a mobile phone with an APP application — — Safety pioneer. With the captured pseudo base station, he sent a test message; Then, open the security pioneer and click "pseudo base station identification". In less than 30 seconds, a short message "stands out" from hundreds of short messages in the inbox. At first glance, it is the one just sent.

　　This self-developed "pseudo base station SMS identification technology" is also based on big data. Collect short message features through the mobile phone terminal, compare them with a large number of short message features of pseudo base stations stored in the cloud library, and check the transmission pipeline at the same time. Generally speaking, whether a mobile user sends or receives a short message, it is recorded in the short message center. If it is not recorded and matches the above characteristics, it can basically be judged as a pseudo base station message.

　　This big data identification technology, which adopts the linkage of end, pipe and cloud, can identify the short messages of pseudo base stations in the province’s ports. The advantage of security pioneer lies in not only the data of mobile phone terminal, but also the data of short message transmission pipeline.

　　Real-time calculation, with the police positioning strike

　　"There is pseudo base station activity near Chebei subway station in Tianhe District". According to the monitoring of Guangzhou Mobile, technicians immediately rushed to the scene to track with instruments.

　　A man riding an electric car came into sight. At first glance, his dress is no different from that of ordinary food delivery staff, but this disguise can’t escape the "eye-catching" of technicians. After the alarm, the public security personnel quickly arrived to control the man and seized a set of pseudo base station equipment from the disguised takeaway box on the spot.

　　Here, the "golden eye" is the "pseudo base station detection and tracking system". "Big data detection, early warning and accurate identification, if only used to remind users ‘ Don’t be fooled ’ The intensity of cracking down on pseudo base stations is undoubtedly greatly reduced. We not only passively prevent, but also take the initiative to cooperate with the public security organs to pull out the pseudo base station. " Kang Yong, the security director of Guangzhou Mobile who is responsible for the pseudo base station attack, said.

　　On the basis of detecting and warning short messages from pseudo base stations, the system performs big data processing to lock a large area where a user’s mobile phone is attacked by pseudo base stations at the same time or continuously; Then analyze the location and moving path of each mobile phone and calculate the accurate location of the pseudo base station.

　　"The current pseudo base stations are often in motion, which requires higher real-time computing power for big data." Liu Shaocong revealed that with advanced positioning technology, the positioning accuracy of pseudo base stations can be controlled at around 100 meters.

　　In the current high-pressure situation of cracking down on telecommunication network fraud, Guangzhou police have treated the pseudo base station case as a major warning and established a linkage mechanism with Guangzhou Mobile. Once the location of the pseudo base station was located in the system, the police immediately dispatched police forces nearby to jointly attack with the road patrol personnel sent by Mobile. As soon as the suspect is identified, arrest him immediately.

　　Since 2015, Guangdong Mobile has cooperated with public security organs to crack 818 cases of pseudo base stations, arrested 1,095 suspects, seized 985 sets of pseudo base station equipment and 456 vehicles, which effectively shocked the illegal and criminal activities of pseudo base stations. According to the relevant network data of Guangdong Mobile, the number of abnormal registration location updates caused by pseudo base stations decreased by 57% year-on-year, indicating that the activity of pseudo base stations decreased significantly.

The Seven Laws Long March

Of the trying long march the Red Army makes light:

Thousands of rivers and mountains are barriers slight.

The Five Serpentine Ridges outspread like rippling rills,

The pompous Wumeng peaks tower but like mole-hills.

Against warm cloudy cliffs beat waves of Golden Sand;

With cold Iron-chain Bridge River Dadu is spanned.

Glad to see the Min Range snow-clad for miles and miles,

Our warriors who have crossed it break into broad smiles.

This poem by Chairman Mao

It is not only a record of the glorious achievements of the Red Army’s Long March.

At the same time, it is also a true portrayal of the arduous journey of the Red Army’s Long March

Zhang Wenyuan’s 1984 oil painting "Grassland Love"

Into the honor room of the 4 th Company of a Red Army Corps in Chengdu Military Region

A black-and-white photo stands out.

There is only one in the photo with a paragraph cut off.

Old cowhide belt

The back of the belt is branded with the words "Long March"

The owner of this belt

Is an ordinary Red Army soldier.

Eighth Company, 274th Regiment, 93rd Division, 31st Army, Red Fourth Front Army

(Now Company 4 of a Red Army Corps in Chengdu Military Region)

Warrior Zhou Guocai

It is such a belt.

Truly witnessed

That hard and hopeful time.

June 1936

Red Fourth Front Army and Red Second Front Army

Victory in Ganzi, Sichuan

Early July

Red Fourth Front Army

Began to cross the vast grassland northward for the third time.

This grassland is located at the junction of Qinghai-Tibet Plateau and Sichuan Basin.

Now this beautiful grassland.

For the Red Army soldiers at that time,

There are dangers everywhere

There is no road.

No food

Only the wind and rain

Marsh trap

And the approaching pursuers

In this difficult situation.

No food.

Belt, leather shoes, gun belt

Even the saddle

Have become the rations on which the Red Army soldiers live.

Although before crossing the grass

The whole army tried every means to raise food.

But because this March is farther than the previous two journeys,

a long time

There is a serious shortage of food.

When I first entered the grass

There are 3 Liang of highland barley noodles per person every day.

But soon the troops fell into a desperate situation of food shortage.

The grassland is deserted.

There is nowhere to replenish on the March.

The rest of the journey had to dig wild vegetables and chew grass roots.

Some soldiers even took it from cow dung

Pick up undigested grains from cattle.

While some soldiers eat poisonous vegetables and weeds by mistake.

Unfortunately poisoned to death.

However, wild vegetables and grass roots are not hungry at all

Some Red Army soldiers thought of eating cowhide belts.

They also created a song "Cowhide Belt Song" based on this.

Cowhide belt is three feet long.

Grassland and wasteland are good dry food.

Don’t smell when you boil water.

Wild fire is cooked and fragrant.

A section for cooking wild vegetables.

A passage for cooking fresh soup.

There are many kinds of soup and vegetables.

Leave a comrade-in-arms taste

Red Army soldier Zhou Guocai was only 14 years old at that time.

There were 14 soldiers in his class.

But when we got to the grass, there were only seven people left

Soon after entering the grass

Their class ran out of dry food.

You can only dig wild vegetables, eat grass roots and chew bark.

Later, even the wild vegetables could not be found.

They had to start eating leather from gun belts and shoes.

But these things didn’t last long and were eaten up.

So everyone took off their belts and cooked.

When the belts of the six soldiers were finished,

Everyone said to Zhou Guocai

"It’s time to eat yours."

Comrades all know.

Zhou Guocai’s belt

It was in 1934 that the Red Army fought in any joint battle.

Captured booty

Zhou Guocai really loathe to give up.

Eat what you love.

But in order to fight hunger

Save the lives of the whole class.

He had to contribute his belt.

Looking at the beloved belt

A belt thread that is finely cut into small pieces.

Drift in the watery soup.

Zhou Guocai couldn’t help crying.

When the front part of the first eye of the belt is finished

He really couldn’t help it.

Cried and begged his comrades to say

"I don’t eat, comrades.

Let’s keep it as a souvenir.

We took it to Yan’ an to meet Chairman Mao. "

that’s it

Everyone is looking forward to the victory of the revolution.

endure the torments of hunger

Will this leftover half belt preserved.

On the subsequent Long March,

Six comrades-in-arms of Zhou Guocai died one after another.

Only he arrived in Yan ‘an with the victory of the Red Fourth Front Army.

In memory of the fallen comrades.

He used iron chopsticks on the back of the belt.

Burn the words "Long March"

Wrap it in red silk.

1975

Zhou Guocai has treasured this half belt for decades.

Donate to the country

Later, it was collected by the Museum of Chinese Revolution (now the National Museum of China)

"The wind and rain soaked the bones harder.

The stronger the ambition of potherb to satisfy hunger.

The officers and men share weal and woe.

The revolutionary ideal is higher than the sky. "

Senior general of the red army

And the treatment of ordinary soldiers is the same.

The National Museum of China has collected half a belt.

The owner of this half belt is Ren Bishi.

Political commissar of the Red Second Army at that time.

When he and his guards

Is to cut a little belt every day

Everyone can eat about three small pieces at a time.

Leftover belts from Ren Bishi’s Long March across the grassland.

For this special ingredient

Soldiers should use special cooking methods.

In order to be able to swallow

Even with special "condiments"

That is optimism.

Burn it and cook it.

Let’s eat together

Although it’s hard.

But they have a very optimistic revolutionary spirit.

They call belts.

"Good dry food in grassland wasteland"

"Boiled beef"

Ren Bishi kept it.

Eat the remaining half of the belt

As a memorial

After the founding of new China

His guard Li Shaoqing

Donate this half belt to

Museum of Chinese Revolution (now China National Museum)

These special "foods" collected in museums

Like a letter through time and space.

Revealing the team led by the Communist Party of China (CPC)

The mystery of steel and iron

Let people more deeply

Got to know this special group of people.

Understand a special belief

Come and give me a compliment before you go ~ ~ ~

Northeast Tiger in Northeast Tiger and Leopard National Park

Northeast Leopard in Northeast Tiger and Leopard National Park

Information picture of Northeast Tiger and Leopard National Park

Snoring soundly, resting in the warm sun, and taking a leisurely walk by the whole family … Wild Siberian tigers frequently appear in the dense forests in eastern Jilin, and almost every appearance can attract people’s attention. Northeast Tiger and Leopard National Park, located in Jilin and Heilongjiang provinces, is the only stable habitat and spreading source of wild Northeast Tiger and Leopard in China.

Tigers roar in the mountains and leopards leap in Qingchuan. As a predator at the top of the food chain, the survival state of the Siberian tiger directly reflects the dynamics of the regional ecosystem and is an indicator to measure the local ecological environment and ecological balance. Protecting the Siberian tiger is also protecting biodiversity and improving the ecological environment on which people depend.

General Secretary of the Supreme Leader pointed out that "it is necessary to speed up the construction of a nature reserve system with national parks as the main body and improve the red line supervision system for nature reserves and ecological protection." In October 2021, at the 15th Conference of the Parties to Biodiversity held in Yunnan, the list of the first batch of national parks in China was announced, and the Northeast Tiger and Leopard National Park became one of the first batch of national parks.

The frequent appearance of wild northeast tigers and leopards reflects that the ecological environment continues to improve and the ecosystem is gradually improved. For a long time, Jilin Province has strengthened the protection of the authenticity and integrity of the natural ecosystem, vigorously protected wild animals such as the Northeast Tiger and the Northeast Leopard, cared for green mountains and green rivers, and protected the natural ecology.

Ecological priority tiger and leopard reproduction

"When I first joined the work, I was still a worker in the forest farm." Zhao Yan, a staff member of the Research Monitoring Center of Hunchun Bureau of Northeast Tiger and Leopard National Park Administration, said. In the past 12 years, with the arrangement of job transfer, Zhao Yan has changed from a forest farm worker to a patrolman, and now to a scientific research and monitoring post, which has witnessed the functional transformation of the forest farm from "logging" to "forest protection".

"When I received the transfer notice, I had no time to prepare too much, so I was arranged to follow the masters to the mountains for field investigation. In a blink of an eye, I have been guarding wild animals and deep forests for 12 years. " Zhao Yan said.

Chunhua Town, Hunchun City, Jilin Province, is located in the jurisdiction of the Northeast Tiger and Leopard National Park. Here, warning signs of "Tiger and Leopard, Pay Attention to Safety" can be seen everywhere.

"When I was a child, I rarely saw wild animals, let alone tigers, leopards and bears. Twenty years ago, even the footprints of roe deer and rabbits were rare." Yu Dongxi, a villager in Tumenzi Village, Chunhua Town, said that in recent years, the environment has obviously improved, and the number of wild animals in the mountains has gradually increased. "If you go up the mountain in winter, you can see the footprints of many different animals on the thick snow."

In 2017, the Northeast Tiger and Leopard National Park launched a pilot system, including 19 nature reserves such as Hunchun Nature Reserve, and the area under its jurisdiction was controlled according to the core protected areas and general control areas. The State Administration of Tiger and Leopard in Northeast China was established in the same year, and it uniformly exercises the management responsibilities of national parks and nature reserves within its jurisdiction.

Northeast Tiger and Leopard National Park spans Jilin and Heilongjiang provinces, with a planned area of about 14,100 square kilometers and a forest coverage rate of 97.74%. It is the historical natural distribution area of Northeast Tiger and Northeast Leopard in China and the only area with wild settled populations and breeding families.

In a short period of four years, great changes have taken place in the Northeast Tiger and Leopard National Park: the quality of the ecosystem has been further improved, human disturbance activities such as grazing have been continuously reduced, the population of herbivores such as sika deer has increased rapidly, the food chain has been rapidly restored, and the adult rate of Siberian tiger cubs has increased from 33% before the pilot to over 50% at present; The distribution range and quantity of butch and leopard population are growing rapidly. At present, there are stable activities of butch and leopard population in more than 50% areas of national parks, and Hunchun area in the core area of national parks is even more grand.

The achievements of wildlife protection are hard-won. "In 1997 and 1998, the first truly wild tiger population survey in the history of China was carried out in Jilin and eastern Heilongjiang. Researchers from home and abroad learned about the distribution and quantity of Siberian tigers in China through the winter line survey and snow traces. Only five traces were found in Hunchun, near the Sino-Russian border. Therefore, at that time, the researchers believed that there was no Siberian tiger population in China that could reproduce and maintain itself. " Feng Limin, an associate professor and doctoral supervisor at the School of Life Sciences of Beijing Normal University, said.

Over the years, Jilin Province has invested a lot of manpower and material resources to carry out arduous restoration and protection of forest ecology. In 2015, Jilin completely banned commercial logging of natural forests. In the deep snow, the sound of chainsaw logging is far away.

"In 2015, a highway and a high-speed railway planned and built in Jilin Province will pass through the hot spots where wild northeast tigers and leopards inhabit and migrate. Once completed, it will become an insurmountable barrier on the road to the return of the Northeast Tiger and Leopard. " Feng Limin said that after learning about the situation, the research team made suggestions. "Jilin Province attaches great importance to it, and does not hesitate to sacrifice economic interests to make way for the ecology and the protection of tigers and leopards. It cancels the planned expressway and diversions the high-speed rail, which has well maintained the integrity of the key habitats of tigers and leopards and the smoothness of the diffusion route."

According to the monitoring data of Northeast Tiger and Leopard National Park, by the end of 2021, the number of wild Amur tigers and leopards in the park had increased from 27 and 42 at the time of the pilot to 50 and 60 respectively, and more than 10 newly bred cubs and more than 7 cubs were monitored.

Scientific monitoring and full-time protection

"Communication depends on snoring, patrol depends on walking, cold protection depends on shaking, and safety depends on dogs." This is a true portrayal of nature conservation management in the past. "The area where the Northeast Tiger and Leopard National Park is located is mostly mountainous, with remote geographical location and weak transportation infrastructure." Feng Limin said that more than a decade ago, people were more dependent on entering the forest, then installing and maintaining equipment, and conducting sample lines and sample plots surveys. It takes a lot of time to collect data and replace equipment batteries in the mountains, but in a short time, only small samples can be obtained in a small area. "Traditional scientific research monitoring methods, theoretical systems and protection practices are difficult to keep up with the actual needs of national park construction."

In 2006, Feng Limin, who was studying for a doctoral degree at Beijing Normal University, came to the snowfield of Linhai in the northeast to pursue the trail of the Northeast Tiger.

"For more than ten years, as the head of the field investigation team, I led the team members to trek in the mountains and forests. In 2005, we purchased a batch of trigger infrared cameras and completed the erection. In this way, after people leave, wild animals will leave images in front of the camera without interference, so that researchers can obtain accurate information such as the time, place and behavior of the target. " Feng Limin introduced.

Through the infrared camera, in 2007, the team harvested the first photo of the wild Siberian tiger; In 2010, the first photo of Northeast Leopard was harvested; In 2012, the first Siberian tiger breeding family was discovered. "From 2012 to 2014, we obtained thousands of video data of tigers and leopards, and identified at least 27 Amur tigers and 42 Amur leopards in China, confirming for the first time that there are breeding populations of Amur tigers and Amur leopards in China." Feng Limin said.

On this basis, after several years of experiments and demonstrations, the research team has integrated modern communication, cloud computing, artificial intelligence, big data analysis and other technologies to form an integrated monitoring system of the Northeast Tiger and Leopard National Park. This monitoring system can not only monitor the activities of wild animals such as tigers and leopards in Northeast China in a long distance and in a large area, but also obtain information on biodiversity, various ecological elements and human activities in real time.

At the beginning of this year, a wild Siberian tiger video was "screened" on the Internet. A wild Siberian tiger cub is sleeping soundly in the clear snow and deep in the forest. The tiger mother waiting by lies on the snow and basks in the sun lazily. The warm picture was sent back through the integrated monitoring system of heaven, earth and air in Northeast Tiger and Leopard National Park.

With the full-time monitoring of the integrated monitoring system of heaven, earth and air, protectors can get the latest situation in the national park, but many specific tasks need to be completed by rangers in the vast forest.

"This step is relatively short, and the width of the palm pad is between 8.5 and 9.5 cm. It should be a female Siberian tiger." "According to the comparison of the side torso patterns, these videos are not the same Siberian tiger." Look at the footprints of tigers and leopards and distinguish between males and females and the route of travel; Observing the surrounding environment and judging the hidden position of the hunting set … Working outdoors all the year round, Zhao Yan has long been familiar with the habits of the Northeast Tiger and Leopard.

Once, Zhao Yan and his colleagues strayed into the territory of a tigress with a cub. "Suddenly, I heard a deep roar from the forest. When I looked up, I saw the shadow flash and disappear into the Woods. " Recalling the experience of passing by the Northeast Tiger, Zhao Yan still has a lingering fear. "Lao shifu, this may be a strong warning from the tiger, and I’m afraid I will be attacked if I go any further. We quickly turned back, and without going out of 200 meters, we found traces of a female tiger with three cubs. "

Daily cleaning, supplementary feeding in winter, and cracking down on poaching … Whether it is midsummer or winter, the patrolmen constantly shuttle through the dense forest and track for shadows, just to protect tigers and leopards. The rangers divided the forest area into grids, and searched and cleaned the hunting covers, hunting clips, sticky nets and poisonous baits in the area in a carpet way. During the mountain cleaning operation, members of each group should keep a safe distance, and record the GPS waypoint information and image data in detail and accurately to ensure that "one piece is clear and one piece is clean". In this unique habitat of wild Siberian tigers and leopards in China, more than 6,800 patrolmen guard it day and night.

After experiencing the ecological restoration, under the long-term propaganda of the patrol, more and more local people have joined the protection team to protect the forest at home.

Co-construction, Sharing and Harmonious Symbiosis

"The Siberian tiger is a rare and endangered wild animal under special protection in China, a flagship species for biodiversity protection and a symbol of the health of temperate forest ecosystems." Kong Weiyao, an expert from the Ecological Protection Department of the Northeast Tiger and Leopard National Park Administration, said, "The living state of the Northeast Tiger directly reflects the dynamics of the regional ecosystem and is an indicator to measure the local ecological environment and ecological balance. The restoration of the natural population of the Northeast Tiger requires rich forest vegetation and prey population and a better social surrounding environment. "

"The protection of tigers and leopards has never only protected tigers and leopards, but involved the improvement of the entire forest ecosystem." Feng Limin holds the same view. He said that "the protection of top species such as the Northeast Tiger and Leopard is a very challenging undertaking all over the world. An adult Siberian tiger needs a very large territory area, even reaching thousands of square kilometers. "

Green mountains and clear waters make tigers and leopards flourish.

A few days ago, some media exposed the newly released 2025 Changan Ford L on the eve of Guangzhou Auto Show, which caused a lot of heated discussion in the car circle.

Generally speaking, the change of Sharp L is more like a "precision strike", mainly focusing on configuration upgrade and some details optimization, and the price has also been adjusted. The entry fee has also dropped by 3,000 yuan, and the starting price has reached 226,800 yuan.

Read the cold first to draw the key information for your reference. First of all, in terms of appearance, the wheel hub style has been upgraded, and the top model also uses more cool two-color wheels.

In the interior part, the top model has increased the choice of two-color and white interior, and the seat has been redesigned to improve the comfort; In terms of configuration, it was upgraded to a 540-degree panoramic image and decentralized to the luxury model; In terms of power, it continues the current 2.0T fuel and 2.0T powertrains.

Specifically, this time I experienced the hybrid ST-Line version. In addition to the eye-catching "ST-Line" logo on the door, what attracted me most was the set of wheels with bright black/silver colors, which was full of sports.

The size is still 19 inches, with 255/60 R19 tires, the visual effect is quite full. In other respects, the design of the current model is basically continued, and the large-size air intake grille and sharp headlights are still very imposing.

Entering the car, the 27-inch 4K huge central control panel is still the focus of the whole interior, and the sense of technology is bursting. This ST-Line version uses a black interior with red stitching to create a sporty atmosphere. The wrapping and support of the seat are not bad, and you won’t feel too tired after a long ride.

Speaking of configuration, the biggest highlight of this change is the upgrade and decentralization of the 540-degree panoramic image. This function is definitely a gospel for novice drivers, which can provide a more comprehensive vision and effectively reduce the risk of rubbing.

Moreover, the top model is also equipped with HUD head-up display, which can display information such as speed and navigation, further improving driving safety.

In terms of power, the hybrid ST-Line version I experienced is equipped with a 2.0T system. The overall performance of this power system is still very good, with rapid start, smooth acceleration and low fuel consumption.

The maximum power of 2.0T engine is 202kW (275hp) and the peak torque is 405nm. The maximum power of the motor is 140 kW (190 HP) and the peak torque is 320 Nm. In actual driving, the power output is very linear and there is no obvious sense of frustration. The smoothness of E-CVT gearbox is also commendable.

Of course, the 2025 Sharp L is not perfect. For example, its third row space performance is still relatively cramped, and it is only suitable for short-distance rides or emergency use. In addition, although the 27-inch central control panel is cool, the logic of some functions is slightly complicated in actual operation, which requires a certain learning cost.

Finally, talk about its competitors. In the joint venture medium-sized SUV market with the price of 200,000-300,000, Sharp L has quite a few opponents, such as,, and so on.

In contrast, the advantages of Sharp L are more fashionable design, richer technology configuration and stronger power performance. But its disadvantages are also obvious, that is, the brand influence is slightly inferior and the space in the third row is insufficient.

So what do riders think of the 2025 Sharp L? What do you think of its change this time?

Personally, I feel that this change of the 2025 Sharp L is quite sincere. The configuration upgrade, detail optimization and price adjustment all reflect Ford’s determination to enhance product competitiveness. If you don’t have high requirements for space and pay attention to technology configuration and dynamic performance, then Sharp L is still a worthy choice.

Finally, add some information about the hybrid model E-CVT gearbox. Many riders may not know much about E-CVT. In fact, it is different from the traditional CVT gearbox. E-CVT mainly relies on planetary gear sets and motors to realize power distribution and stepless speed change, which is more efficient and reliable. Simply put, it can not only ensure a smooth driving experience, but also give consideration to fuel economy.
