Beijing, March 1 ST "The 19th National Congress of the Communist Party of China proposed to build an educational power, which is an arduous, historic and grand task. To build an educational power, we must first improve the quality of basic education, and we must first improve the quality of Chinese and mathematics." Recently, Wang Wenzhan, former director of the Department of Basic Education of the Ministry of Education and deputy chief inspector, said this at the launching ceremony of the national "Shui Mu Hsinchu Yingchun Cup" national youth mathematics comprehensive ability exhibition sponsored by the Central Network Film and Television Center of the Communist Youth League, undertaken by Future Network and Shui Mu Hsinchu Education, and supported by the Education Research Center of China Teacher magazine.

Lord Yue Zun has taken on a new job.

Recently, a new drama in Dylan was launched. This drama is the costume drama "Floating Figure" starring him and Yukee Chen’.

Because of the popularity of Dylan, I heard that the number of reservations for this drama exceeded one million before it started.

To say how hot Dylan is, since the launch of "Freesia Tactics" a while ago, Yue Zun’s adult has been out of the circle almost every day, and 800 hot searches directly build a nest and settle down on the hot search every day.

In addition, these two days, the new drama began to broadcast, and the hot topics were one after another. There was a kind of entertainment that seemed to have no one but him.

01 New Drama Controversy

Speaking of the new drama "Floating Picture", this is his first work since the popularity of "Freesia", so it has attracted everyone’s attention.

However, after the play was broadcast, the comments were polarized. Some netizens think that the plot of this drama is novel and it is a cool drama without delay. However, some viewers think that Dylan’s makeup and hair styling is still ugly, and her acting skills are a little off-line. The acting skills of the hostess are even more complicated, and the audience’s comments are mixed.

Some people have given the play a five-star praise, and feel that the setting is novel and has a sense of humor, which will give people the desire to watch it.

In view of the appearance of the male host and the acting skills of the female host, many people directly made a one-star bad review, and their words were sharp.

Judging from the broadcast episodes, the hostess is clever, happy and cute, but the netizens’ comments on Yukee Chen”s acting skills are almost meaningless. A pair of beautiful and moving eyes are not the case when put into the performance. Because of the eye play, Yukee Chen’ was also crowned as "Wood Beauty" before.

Just look at this photo, please analyze the psychological activities of the characters.

Option 1: A group performance in front of the hostess made an incredible and amazing move.

Option 2: When the hostess went out, she suddenly remembered that she had locked her key at home.

Option 3: The hostess is about to be locked up in the tower, and she will take a last look at the world with the attitude of death.

The correct answer is the last one.

But the first two options seem to be more in line with Yukee Chen”s eyes at this time.

Therefore, many netizens complained that Yukee Chen’ Yan value, the heroine, was online, but her acting skills were dull and she stared like two bells, which made people very dramatic.

The netizen said that he thought that the hostess’s hip-pulling performance could be made up by Dylan, but he never imagined that he also overturned the car.

It may be that his role in "Freesia" is so amazing that Xiao Duo’s role is eclipsed.

Everyone knows that Dylan’s face is the most attractive thing. I don’t know whether it’s a stylist’s standard or a character setting. The hat Dylan wears on his head makes him look a little strange.

Coupled with a purple costume and a makeup that doesn’t match, I have to say that this makeup was shot at some death angles, which greatly reduced the handsome degree of Yue Zun’s adult.

In terms of acting skills, netizens commented that Dylan was too dull. In many plots, he prefers to talk with his neck stuck. Moreover, only the male and female actors are dubbing in the whole play.

02 Lucky Resource Coffee?

In others’ eyes, Dylan seems to be a very lucky existence in the entertainment circle, and some even call him Resource Cafe. But looking back on Dylan’s career, he has actually been working hard. After all, it’s so hot now. If we only rely on luck, Dylan probably won’t be where he is today.

Dylan once participated in the reality show variety Superdimensional Idol and starred in the mainland versions of Meteor Garden and Night Two, but none of them aroused much splash.

Until then, I took the play yu long. The heat was there at that time, but it was a uniform stigma.

Dylan has become synonymous with the ugly man in ancient costume and acting skills, and the tucao video at a certain station has reached millions of broadcasts.

Even so, he took the characters seriously. During the broadcast of yu long, Dylan printed his book list on Weibo. It seems that I have thought a little bit about the plot. At the same time, this has also been questioned by netizens: Who knows if this is "pretending"?

There are also actresses who play against him, saying that he will recite the other party’s words in order to be more smooth and substitute.

There is no idol burden to participate in the variety show, and it also presents the scene of watermelon head’s fame.

Later, with the drama "Freesia Tactics", Dylan’s popularity increased, and the director also stood up and praised him.

After the fire, Dylan was as busy as a bee.

Take on a new play as the leading actor.

All kinds of attendance activities, invited to participate in the GQ ceremony of the red carpet shine.

Even the big show of luxury brand LV invited Dylan to be present.

But even so, he has no airs, and he still tries to seize the opportunity to advertise himself, asking the producers and directors to find their own films. This kind of Dylan can be regarded as a down-to-earth and real person.

In addition to acting in a down-to-earth manner and working hard, he is also a rare real person in private.

Dylan’s family is average, and his father sells fried skewers. Before that, he often went home to help his family sell fried skewers.

Even Eric Wang, who has always been serious, praised him on the show: "He is essentially a rare person in this era, and he goes straight to that kind …".

You have to speak with acting skills and works.

Looking back at the stars of entertainment flow, YiBo, Dylan, Leo, Zhao Lusi … Nowadays, one after another, the flow is rising, dividing up the cake of entertainment circle. When someone comes in, someone will eat less or go out. In fact, they are not disturbing the water in the pool, but to increase the vitality of the water in the pool, but the increase of one person’s flow will inevitably affect another person’s exit.

In addition, some netizens spit out that the status quo of entertainment artists is that they pull their legs on the stage, dance and paddle, get together and act, and they are not good at acting, doing things that they were not good at, and they can’t figure out their position. Therefore, the current traffic stars are still full of various controversies.

Chen Daoming, a veteran actor, once said at a symposium: The so-called stars are not from the literary and art circles, but from the traffic circle. They are plastic actors hyped by packaging. Although it is also active in this industry, it has affected the reputation and reputation of many excellent creators.

Indeed, it seems that the acting level and personal problems of the entertainment personnel still need to be improved. After all, the artists in the entertainment circle have subverted the public’s cognition again and again, so that we can’t see the bottom line of entertainment.

Nowadays, Dylan’s new drama "Floating Edge Map" has been launched, although the controversy continues, but the popularity has not diminished. There is also a modern drama "Taking Love as a Camp" to be broadcast. I don’t know what comments these follow-up netizens will give, but what is certain is that his challenge is still not small.

Dylan’s hope of becoming popular will not be just a flash in the pan, but how far he can go still depends on whether he can keep up with the works and enthusiasm in the future, and how he can keep it. Besides, there are still many voices questioning Dylan. If you want to prove your strength, you will ultimately depend on the quality of your works.

And his explosion has brought a lot of pressure to other artists. I hope everyone will not relax their vigilance, or they will work harder.

In a word, having the chassis depends on how Dylan will go in the future.

The wrist injury of Zhu Ting, the core attacker of China women’s volleyball team, is an important reason.

Special feature of 1905 film network In the last shot, Tommy Tam handcuffed himself with Leslie Cheung’s handcuffs, and also handcuffed the originally broken Song brotherhood back; After 31 years, the first official poster is two handcuffed hands, and behind it is still about brotherhood.

　

*Intertextuality between the Final Scene of Hero and the Poster of Chasing.

　

Last Friday, "The True Color of Heroes" was released for more than 30 years, and it was restored for the first time in mainland China, and it monopolized 20 million box office in just three days. Many people go into the cinema to relive this classic Hong Kong film, perhaps for the sake of "brother" Leslie Cheung, perhaps for the sake of Mark with a long trench coat, or perhaps for the sake of enjoying John Woo’s violent aesthetics exclusively.

　

　

Then this Friday, the film Chasing officially landed in the cinema. This film is a Chinese gun battle film made by John Woo after 25 years. After the series, the master of violent aesthetics has gained more tenderness, which seems to be more appropriate to describe with his own debut, and it is a kind of "iron man’s tenderness" temperament.

　

Chasing is a master’s idolize

　

"I have always admired Gao Cangjian very much." Wu Yusen has said this sentence for more than ten times.

　

　

This sentence is not simply for film promotion, but a master’s heartfelt recognition of the actor superstar. In the early days, John Woo started to use Chow Yun Fat, just because of his similar temperament with Gao Cangjian. Even in the modeling of the film, letting Chow Yun Fat wear sunglasses and a trench coat is a tribute to Gao Cangjian.

　

It’s just a pity that John Woo, who has cooperated with Tom Cruise, Ben Affleck, Nicolas Cage and other first-line Hollywood actors, has never been able to form a cooperation with Gao Cangjian. Now, it is in memory of Gao Cangjian that the present Hunting is produced.

　

* The original "Crossing the River of Anger"

　

In fact, the process of winning the copyright of Hunting is also very bumpy. As the Japanese film "Chasing" was unwilling to sell the film copyright, Huanya directly bought the copyright of the original novel "Crossing the River of Anger" and found Wu Yusen, hoping to complete a new adaptation with his personal style. The views of both sides just fit, so this work came into being.

　

　

After all, the adaptation of this version of the story has become the most "difficult" thing. The original novel is a story that happened in the 1960s, and many events and events are out of date for the present. At the same time, there are also concerns that the audience will compare the two versions of the film. As a result, a team of seven screenwriters led by Chen Jiashang adapted the whole story into an escape story in a modern city.

　

Although from the film title signature, neither the scriptwriter, editor nor producer belongs to Wu Yusen, but the content style is still another extension of his "violent aesthetics", and the iconic symbols such as "Double Heroes" and "Dove" are all available.

　

After watching John Woo’s works in different periods for two weeks, I can feel that Wu Dao seems to have changed, but he seems to be the same John Woo who can successfully make Hollywood commercial movies.

Domestic Suzuki New Alto appeared in Beijing.

　　Recently, when Sohu netizens went to a 4S shop in Changan Suzuki for maintenance, they found a new Alto parked in the corner of the shop, which had been heated by major media. They walked over and observed it carefully, and found that the whole car was fine in workmanship, and the pink metallic paint was very bright. The teardrop-shaped headlights on the front of the car were the highlights of the whole car, which raised a lot of spirits for this car. The large-mouth grille follows the design idea of big brother Audi, but it has a lovely appearance on Alto’s little face. The Suzuki "S" chrome-plated logo on the big mouth is huge and eye-catching, which plays a finishing touch for this cute and playful little face.

Car side modeling dynamic fashion body length 3500mm.

　　The side shape of the car body feels familiar. The relatively long front door and short rear door are typical design ideas of a five-door mini-car. The lower edge of the window that rises all the way extends from the A-pillar to the C-pillar, which is dynamic and fashionable. However, due to the body length of 3500mm and the narrow rear door design, the rear door window has become a triangle-like shape. However, the domestic Alto of Changan Suzuki version is different from the European version. The rear door window does not use a low-cost negative pressure ventilation window, but is replaced by an electric lifting window to cater to the tastes of Chinese people, which greatly improves the convenience of use. The overall shape of the side of the car body is similar to that of Global Hawk Panda and BYD F0 listed earlier, which is fashionable and full of vigor.

　　The domestic new Alto’s wheelbase of 2340mm belongs to the middle and upper class among mini-cars, which is longer than that of Global Hawk Panda and BYD F0, and similar to that of Changan Benben of 2365mm. The body width of 1600mm is slightly narrower than that of competitors, and the height of 1470mm is basically the same as that of Panda and F0, and slightly shorter than that of Changan Benben.

Unique tail shape

The tailgate opening is slightly narrow and the trunk is shallow.

　　The shape of the rear part of the car body is unique, probably because the bumper is lifted to a higher position to protect the shorter car body, and the whole rear wall occupies about 2/5 of the rear of the car, which is very full. However, this design also brings inconvenience, that is, the opening of the tailgate becomes higher, and the fashionable three-dimensional crystal diamond combined taillights occupy a large area, which makes the opening of the tailgate narrow, the depth of the trunk is shallow, and it is difficult to enlarge something. The overall shape of the tail is avant-garde, and the logo of Changan Suzuki shows its domestic identity. The high-position brake lights are dotted on the small tail behind the roof, which not only attaches importance to safety but also does not lose fashion.

Design of front McPherson independent suspension and rear trailing arm independent suspension plus lateral stabilizer bar

　　In the aspect of suspension, the new Alto adopts the typical small car design of front McPherson independent suspension and rear trailing arm independent suspension plus lateral stabilizer bar, which saves cost and chassis space while ensuring certain comfort.

Alto adopts 155/65 R14 Jinhu tire and 8 aluminum alloy wheels

　　In terms of wheels, the new Alto high-profile model uses 14-inch 8 aluminum alloy wheels, which are fashionable in shape. 155/65 R14 Jinhu tire seems to be not very kind, and its main competitors are almost all 165 treads. The narrower tire reduces handling but has an advantage in fuel consumption.

　　Like domestic cars with the same price, New Alto is equipped with front disc and rear drum brakes, which is enough for cars with less than 1 ton.

　　Open the door and get into the car. Like Swift and SX4, the interior of the new Alto focuses on simple and fashionable routes, with the same color scheme as the mainstream sedan. The steering wheel shape makes people see at a glance that this is a Suzuki model, which is exactly the same as SX4 and Swift. It is made of PVC, but it looks very big in the petite cockpit of Alto, and it should be more harmonious if it can be designed with smaller points. The new Alto dashboard has a distinctive shape. The huge speedometer occupies the front of the driver’s line of sight. Under the orange background light, the automatic gear position is displayed, and all kinds of warning lights are arranged around the speedometer. On the LCD panel below, information such as clock, mileage and fuel gauge is integrated. The cancellation of the water thermometer shows Suzuki’s confidence in the product.

　　The highlight is the new Alto’s tachometer. On the dashboard in front of the driver’s line of sight on the left, a tachometer is independently designed, which is similar to BYD F0’s design, except that the new Alto’s instrument uses a red background light with a scarlet letter on a black background, which is very outstanding in modification style and adds features to the overall interior modeling.

　　Looking at the whole interior, the new Alto, as a joint venture model, has no outstanding advantages in terms of materials and equipment quality. Under the cost control, the overall level is close to that of domestic models. In terms of vehicle configuration, this experience is an automatic top-mounted vehicle. The gear shifting mechanism is the same as that of Swift, and the shape of the gear shifting base and handle is basically the same. Double airbags, ABS brakes, manual air conditioners, electric rearview mirrors, four-door electric windows with central door locks and remote control keys have become standard equipment for high-equipped vehicles, while four-speaker single-disc CD audio and AUX interface cater to the tastes of young people. The seat adopts manual 4-way adjustment, and the material is a combination of gray flannel and light leather material. In design, the front seat uses the integrated design of seat headrest and has the logo of ALTO, which makes it more comfortable to sit on, but the wrapping is not strong. The headrest of the rear seat is detachable, but the backrest is straight, so I’m afraid it’s uncomfortable to sit for a long time. The whole interior is mainly practical, and there are many necessary conveniences and equipment, while others can be saved. The interior made of plastic and flannel is basically in line with the market positioning of Alto, a mini car.

　　In terms of space, as long as the height is not higher than 185cm, the head space is still sufficient, while the leg space is slightly cramped. There is no problem in short-distance transportation in the city. If you are too tall for a long distance, you will feel bad.

　　It is understood that this car is a trial version of the model, and it is still quite different from the model listed later in the interior and engine compartment.

　　When the car is on fire when the sales are not available, I feel that the sound of ignition is fragile and light. During idling, the car vibrates very little. You even suspect that it uses a 3-cylinder engine, giving people the feeling of a high-end car. Suzuki K10B is really a good machine. Listen to the idling noise on the door. If the tachometer doesn’t point to 800 revolutions, I even doubt whether the engine is running. I found the secret of silence when I opened the hood. It turns out that the new Alto is there. On the nameplate below the car body, the engine power is written as 48Kw, and the compression ratio is reduced and adjusted compared with the previously publicized machine with 50Kw compression ratio of 11: 1. In order to adapt domestic Alto to the ration of 93rd gasoline, it is worthwhile to sacrifice some power.

　　Due to the small space, I didn’t test drive for a short experience, but I was deeply impressed by the new Alto. Typical urban scooter and automatic transmission models are very suitable for shuttle in cities, and the 1.0L engine has obvious advantages in fuel consumption. In terms of energy saving and styling design, it has won the favor of many people. In September, the new Alto will be listed soon. In the highly competitive car market, the role of price guiding sales is very obvious. The new Alto has already occupied the absolute advantage of brand and reputation. So, can this old car sell well? Let’s wait for the price of the new Alto, and please continue to pay attention to Sohu Auto’s follow-up reports on the new Alto.

Nowadays, there are many kinds of cars, and all kinds of models are dazzling. At this time, we should proceed according to our own reality, and the right one is the best. There are many car choices now, such as Volkswagen ID.3 that we talked about today. Let’s take a look at it together.

Let’s take a look at the appearance of Volkswagen ID.3. The front face of Volkswagen ID.3 gives people a very simple feeling and is very sporty. Combined with fashionable headlights, it is the finishing touch on the front face. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light, delayed closing, rain and fog mode and so on. Coming to the side of the car, the body size of the car is 4261MM*1778MM*1568MM, the car adopts moving lines, and the side wall presents a unique design style, which is quite avant-garde with large-sized thick-walled tires. In the rear part, the rear of the car echoes the front face from a distance, and the taillights look very stable and comfortable.

Coming into the car, the interior of Volkswagen ID.3 presents a sharp design style, highlighting the hierarchical effect. The car looks very good outside the steering wheel, and it is made of leather, which makes people love it. From the central control point of view, with the 12.9-inch touch-sensitive LCD central control screen, the interior style is impressive and looks very round and lovely. The interior feels good. Let’s take a look at the dashboard and seats. The car is equipped with a sharp dashboard, and the trendy design elements make people remember it at a glance. The car adopts leather seats, which are wide and thick, and improve the riding experience of drivers and passengers.

The Volkswagen ID.3 is 125KW, the total torque is 310N.m, and the maximum speed is 160 km/h..

The performance of Volkswagen ID.3 trunk space is relatively good, the opening size is in line with the positioning of its family car, and the family’s storage needs can be met. At the same time, the car is equipped with fatigue warning, anti-lock braking (ABS), LED daytime running lights, brake assist (EBA/BAS, etc.), brake force distribution (EBD) main driver airbag, co-pilot airbag, side airbag curtain, front side airbag and other safety configurations.

After reading this car, I believe you have a general understanding. The car introduced today is not only eye-catching in space, but also has reached the mainstream level in various configurations, and there is nothing to be picky about driving experience and space experience.

Core reading

Northeast Tiger and Leopard National Park spans Jilin and Heilongjiang provinces, with a forest coverage rate of 97.74%. Since its official establishment in October last year, the distribution range and number of tiger and leopard populations in the park have achieved steady growth. In recent years, the Northeast Tiger and Leopard National Park has continuously promoted the construction of an integrated monitoring system of "heaven, earth and air", explored the informationization and intelligent management mode of natural resources in national parks, and strived to achieve a win-win situation for ecological protection and improvement of people’s livelihood.

In early winter, it is very quiet in the hinterland of Northeast Tiger and Leopard National Park in Hunchun City, Jilin Province. Here, through a mobile phone, you can grasp which areas have recently seen wild animals such as Siberian tigers, Siberian leopards and sika deer. This is due to the integrated monitoring system of "heaven, earth and air" built by the Northeast Tiger and Leopard National Park.

"The integrated monitoring system of’ Heaven, Earth and Air’ has realized the real-time feedback of the wild Northeast Tiger and Leopard videos. This brand-new information and intelligent management mode of natural resources in national parks can better help the construction of national parks." Feng Limin, deputy director of National Forestry and Grassland Administration Northeast Tiger and Leopard Monitoring and Research Center and head of field work of Tiger and Leopard Research Team of Beijing Normal University, said.

Carry out scientific research cooperation and explore the establishment of an integrated monitoring system of "heaven, earth and air"

"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 in the 10 years since 2005, the Tiger and Leopard research team of Beijing Normal University installed 3,000 infrared cameras in the deep mountains and forests in Jilin and eastern Heilongjiang.

Professor Ge Jianping, the founder of the Tiger and Leopard Research Team of Beijing Normal University, who was then the vice president of Beijing Normal University, is also pondering over the technical support that is more suitable for related protection work. In the autumn of 2016, Ge Jianping led Feng Limin and other team members to drive around the area where the Northeast Tiger and Leopard National Park is now located.

"For 7 days, I walked through the mountains and went to the forest to find the answer." Feng Limin recalled that along the way, a kind of "black pole" was erected along the way. Everyone got off the bus and observed that these "black poles" were erected for fttp in the "every village" project of radio and television. "I feel that the’ key’ was found at once." Feng Limin said that the extensive coverage of the optical fiber system means that the national park informatization has a ready-made "highway trunk road".

The cooperation soon began. The Tiger and Leopard Research Team of Beijing Normal University and relevant media organizations carried out interdisciplinary innovative technology research and development, and at the same time, dozens of high-tech companies in the United Nations finally explored the successful adaptation application of 700 MHz wireless band in forest environment, and completed the research and development of a series of key components and equipment such as real-time transmission ecological monitoring equipment, terminal communication module and interface, and management platform.

Since its opening in February 2018, the coverage of the natural resources monitoring system of the Northeast Tiger and Leopard National Park has continued to expand, and it has gradually developed into a comprehensive "heaven, earth and air" integrated monitoring system.

On the way into the mountain, Feng Limin pointed to a tower on the hill in the distance and said that this was the past forestry fire prevention observation tower, and now it is equipped with the base station antenna of the "heaven, earth and air" integrated monitoring system of the Northeast Tiger and Leopard National Park. At present, more than 60 of the 95 base stations have made use of the existing forestry fire prevention observation towers, which not only saves a lot of money, but also protects vegetation to the greatest extent. At the same time, this system is also equipped with and integrated with fire-proof electronic eyes, which can realize all-weather unmanned intelligent duty.

Up to now, the integrated monitoring system of "heaven, earth and air" has installed more than 20,000 field monitoring terminals, such as wireless infrared cameras, which can transmit in real time, and has transmitted and recognized images of Siberian tigers and leopards in real time for more than 30,000 times.

Maintain monitoring system to improve the efficiency of daily patrol and management.

At dawn, Han Changxue, a villager in Sidaogou Village, Chunhua Town, Hunchun City, has taken up his backpack, lunch box and kettle, and started a day’s work with several villagers in the same village. "We set out for patrol every morning and come back at two or three in the afternoon." Han Chang’s theory.

Han Changxue, who has been farming for decades, joined the peasant patrol team organized by the village last year and became a patrol officer. After professional training, he has been able to expertly remove hunting traps, identify animal activity tracks, and participate in and assist the research team in some scientific research work.

"Just a few days ago, when we were patrolling in the mountains, we heard the sound of a leopard." Han Chang said, "We immediately stopped and slowly withdrew from this mountain forest." Han Changxue said that the significance of patrol is to protect wild animals, and of course to protect their own safety.

In the Northeast Tiger and Leopard National Park, more than 6,800 patrolmen shuttled through the dense forest to protect wild animals. More and more local people have joined in to protect the green mountains and rivers at home.

The integrated monitoring system of "heaven, earth and air" has effectively improved the efficiency of daily patrol and management. Combined with the intelligent analysis results of big data, the joint dispatching command center can issue multiple monitoring and management instructions to help multiple field teams to complete related tasks in an orderly manner according to the instructions. "In recent years, we have participated in more than 580 large and small maintenance work, repairing and replacing field digital communication equipment, base station antennas and power supply equipment to fully ensure the normal operation of the monitoring system." The person in charge of the relevant unit responsible for the maintenance of the integrated monitoring system of "heaven, earth and air" introduced.

Through the strength of science and technology, we can achieve a win-win situation for ecological protection and improvement of people’s livelihood.

In the Northeast Tiger and Leopard National Park, you can often see warning signs of "Tiger and Leopard haunt, pay attention to safety".

Next to a stout tree, the reporter found an infrared camera erected here. "In order to protect the safety of villagers’ life and production, we will set up infrared cameras and other equipment in areas around the village where tigers and leopards may appear, and give villagers real-time warning." Feng Limin said.

Near the demonstration park of Actinidia arguta planting industry outside Sidaogou Village, Chunhua Town, Hunchun City, infrared cameras are also under control. In 2017, with the support of the town and the technical guidance provided by Yanbian University, Sidaogou Village planted Actinidia arguta. "It used to be a wasteland, but now it is an important industry in the village." Tan Changji, the village party secretary, took out his mobile phone and said that with real-time monitoring, he could see the dynamics of the orchard in real time at home and get early warning when wild animals such as tigers and leopards passed by.

"National park construction can achieve a win-win situation of ecological protection and improvement of people’s livelihood through the power of science and technology." Feng Limin said. Since its establishment, the integrated monitoring system of "heaven, earth and air" in Northeast Tiger and Leopard National Park has produced a huge amount of monitoring data, which will provide rich resources for the communities around the national park to carry out activities such as nature education and leisure experience in the next step, and provide strong help for the local transformation and development of sustainable industries such as eco-tourism.

"The completion of the integrated monitoring system of" heaven, earth and air "in Northeast Tiger and Leopard National Park has laid a solid foundation for promoting the modernization of the management system and management capacity of Northeast Tiger and Leopard National Park." Ge Jianping introduced that the system has been identified by National Forestry and Grassland Administration as a science and technology support model for nature reserves that can be used for reference, promotion and replication, and has been gradually popularized and applied in Qilian Mountain National Park, Hainan Rainforest National Park and other nature reserves.

Under the protection of science and technology, the population of wild Siberian tiger and leopard in Northeast Tiger and Leopard National Park is growing rapidly. The number of Siberian tigers and leopards has increased from 27 and 42 in 2015 to over 50 and 60 respectively, and the adult rate of Siberian tiger cubs has increased from 33% before the pilot to over 50% at present.

　　In March 2017, the National Office of "Combating Pornography and Illegal Publications" and Tencent held the activity of "Children’s Cyber Security Course Entering the Campus" at Xiaobei Road Primary School in Yuexiu District, Guangzhou, which was welcomed by teachers and students.

　　People’s vision

　　With the rapid development and comprehensive popularization of mobile Internet and smart devices, it is more convenient for teenagers to contact the Internet, and the age of contact with the Internet is showing a trend of younger age. Moderate use of the Internet can enrich life and relieve stress, but the social experience of teenagers is insufficient, and their network literacy and online habits are in the forming stage. How to help teenagers use the Internet healthily and effectively and guide them to actively adapt to the Internet age is an important and urgent topic.

　　The generation of teenagers after the Millennium are truly "Internet aborigines", and they have a natural and inseparable connection with the Internet. Internet has become the most important space for entertainment, education, self-expression and communication and interaction of this generation. At the same time, however, the rapidly developing and mixed cyberspace makes this generation of teenagers more vulnerable to physical and mental shocks and even injuries. The protection of teenagers online has become the most concerned social issue for governments, international organizations and every family.

　　At present, one third of the global Internet users are minors. In Britain, Canada, Czech Republic and Israel, 12-mdash; The proportion of 14-year-old children using the Internet exceeds 95%, and the proportion of children using the Internet in EU countries is mostly higher than 65%. In China, the number of netizens under the age of 19 reached 171 million, and the Internet penetration rate of minors remained above 90%. At the same time, the young age trend of minors’ first "touching the net" is obvious. Relevant statistics show that Britain has 5-mdash; More than half of the 6-year-old children have access to the Internet. The average age for Korean children to get their first smart phone is 8 years old. There are about 23 million netizens under the age of 10 in China, and more than 56% of them have been exposed to the Internet before the age of 5. These "Internet aborigines" born after the Millennium almost "surf the Internet as soon as they are literate", and the Internet has profoundly influenced the way they interact with the world.

　　More and more "millennials" have become "low-headed families"

　　With the high popularity of home broadband and hardware equipment, minors generally choose to surf the Internet at home. According to UNICEF data, in Argentina, Serbia and South Africa, more than 90% of minors surf the Internet at home; The survey of children’s online use in Britain also found that 75% of them are 9-mdash; 19-year-olds use the Internet at home; America 2— Of the 17-year-old population, 78% can surf the Internet at home, and 13% of them surf the Internet in their own rooms. According to the annual survey data of China Internet Network Information Center (CNNIC) since 2007, the proportion of minors using computers to surf the Internet in Internet cafes, schools and public places has generally decreased year by year.

　　The report "Investigation on Internet Use and Protection of Young Netizens in China" shows that 74.6% of young netizens in China use smart phones to surf the Internet, and 60.4% of young netizens have their own smart phones. Desktop computers rank second, and their adoption rate is about 10 percentage points lower than that of smart phones. Smart TV has become one of the main channels for teenagers to surf the Internet. Many parents also choose smart TV to accompany preschool children, but the digital gap between different regions is more obvious.

　　Information and communication technology has changed the way minors contact with the world, and cyberspace has attracted them greatly, so the online time has been prolonged. A study in Denmark found that as children grow up, their use of the Internet is increasing, and similar trends have appeared in other countries. In China, in recent years, the online time of minors has generally increased. The online time of primary school students is 14.9 hours per week, and that of middle school students is 22 hours per week. The online time is also increasing with age.

　　According to the report of the International Telecommunication Union, the main reasons for teenagers to surf the Internet include: making friends in the new environment, communicating in real time on common interests, creating and sharing original personal content, sharing music, playing games, establishing their own space, or trying new identities. Therefore, the Internet is always with them — — In their pockets or ears, or tightly held in their hands, embedded in their study and living space.

　　A survey of five Nordic countries shows that 9-mdash; Among 16-year-old boys, 69% use the Internet to play games, 49% download music, while girls use it to send emails (58%) and do their homework online (43%). According to the latest data of CNNIC, the Internet applications with the highest penetration rate of underage netizens in China are: instant messaging tools, search engines, online music, online videos and online games. Among them, the popularity of search engines, online music and online games among minors exceeds that of netizens as a whole, and the utilization rate of online games among middle school students is even as high as 70%.

　　The phenomenon of minors’ internet addiction is becoming increasingly serious.

　　Compared with the rapid development of cyberspace, the education and protection system for teenagers to use the internet has shown its lag and imperfection. At present, young netizens all over the world are facing the risks of contact with bad information, bad social interaction, property loss, illegal crime, internet addiction and lack of cognition.

　　According to statistics, 46% of young netizens in China will come into contact with bad information on the Internet almost every time or often, among which pornographic information is the most frequent type, followed by online fraud, online gambling, online abuse and intimidation. It is worth noting that teenagers often come into contact with bad information in a passive way, for example, when clicking on a web page, pictures and videos containing pornographic and violent information pop up, and when browsing information, they see indecent pictures inserted in them. There are not only illegal websites among the websites that spread bad information, but also many regular legal websites often attract attention with bad information in the form of "scratching the ball". At the same time, the uploaders, websites or their host service providers of such content are often not in their own countries, which further increases the difficulty of governance in various countries and regions. On the other hand, the bad information on the internet has a serious negative impact on the concept and psychology of minors, and even leads to crime.

　　According to internet society of china’s Investigation Report on the Protection of Internet Users’ Rights and Interests in China, Internet users suffered economic losses of 133 yuan per capita due to spam, fraudulent information and personal information disclosure, with a total loss of about 91.5 billion yuan. In addition, teenagers are increasingly dependent on the Internet.

　　In addition, the phenomenon of internet addiction is also on the rise around the world. Many studies have shown that there is a high correlation between interactive internet use behavior and internet addiction, such as chatting through instant messaging tools or playing online games, which makes users more addicted to it. Therefore, in the era of mobile internet characterized by interaction and participation, with the rapid penetration of the network into younger groups, the problem of internet addiction among minors is becoming increasingly serious.

　　The academic circles believe that teenagers should spend no more than 1.5 hours a day and no more than 10 hours a week on the Internet, while teenagers generally spend too much time online: 30% of minors in South Korea spend more than 2 hours a day on the Internet, while primary school students in China spend 1.5 times as much time online as this standard, and middle school students even spend twice as much time online. The data also shows that China’s 6-mdash; 47.9% of 11-year-old young netizens usually spend more time online than expected, 12-mdash; Among the 18-year-old young netizens, 60.8% want to surf the Internet when they have free time, which generally shows strong network dependence. Immersion in the online world often brings instant pleasure experience to minors, but their anxiety and fear also increase with the increase of online time, so they are often in a state of frustration and impatience. At the same time, excessive internet access may also strengthen personal loneliness and cause social retreat.

　　Family factors are the key factors that affect minors’ internet addiction. However, many parents and guardians regard mobile phones and computers as "electronic nannies" and neglect the care and education of their children. Teenagers who don’t feel the warmth of their families are more likely to seek spiritual sustenance in the online world, further causing a vicious circle.

　　Strengthen the cultivation of skills and literacy in using digital tools.

　　How to protect minors’ online safety? At present, there is no quick answer, which requires all sectors of society to take countermeasures and persevere.

　　First of all, governments should promote the construction and improvement of relevant legal systems in terms of content, channels, platforms and operations as soon as possible according to the characteristics and development laws of information and communication technologies. Relevant laws and regulations should clearly define the responsible subject for protecting minors’ online safety, clearly define the scope of application and punishment measures, and provide reliable protection for minors’ online activities.

　　Among them, the Internet regulatory authorities should constantly upgrade and update technical supervision means, and guide relevant websites to be equipped with age verification systems or identity verification mechanisms, and at the same time establish a rapid reporting and handling mechanism to promptly punish illegal and illegal behaviors that endanger minors’ online safety. Internet companies and related industries should conduct self-examination and self-examination, eliminate pornography, violence, vulgarity, gambling, fraud and other bad information content, and purify the Internet environment; All kinds of websites should set a higher default privacy level for the collection, processing and storage of minors’ personal data to protect minors’ information from illegal collection and use.

　　Enterprises can adopt appropriate technical measures to encrypt specific information content according to age, or add access age authentication mechanism according to relevant laws and regulations; At the same time, provide concise reporting tools, delete bad information in time, and transfer information suspected of online fraud, abduction and sexual crimes to public security and relevant law enforcement departments. Enterprises should also support the research and development of parental monitoring tools to help parents intervene in their children’s online time, or limit the consumption of certain content and services by minors, or control the objects they talk to online.

　　In the new scientific and technological environment, mastering the skills of using digital tools and having information and media literacy will become the basic survival skills of citizens. Therefore, teaching students how to use the Internet reasonably, legally and moderately is a task that the education sector must shoulder at present. Teachers should update their knowledge system as soon as possible, teach basic knowledge of network security and self-protection in relevant classes, and encourage students to actively seek help from teachers and schools when encountering difficulties, so as to become a trusted social support force for minors. Teachers should also regularly carry out psychological counseling against cyber bullying to prevent students from participating in cyber bullying or becoming targets of bullying; Once the cyberbullying incident is discovered, the school should intervene and stop it in time, and communicate with parents. For serious cyberbullying incidents, it should report to the police in time. Primary and secondary schools should gradually offer network security courses and media literacy courses suitable for students of different ages, systematically teach the knowledge and skills of receiving, analyzing, evaluating and creating information, and gradually improve the media security literacy, media interaction literacy, media learning literacy and media cultural literacy of minors.

　　Faced with the new thing of the Internet, parents can no longer rely on their own experience to guide their children as in traditional families. Instead, they should first take the initiative to learn relevant network security knowledge, be strict with themselves, reasonably arrange online time, and set an example by not browsing or spreading bad information.

　　Parents should also actively guide and educate their children to surf the Internet from several aspects: in terms of time, strictly control the total length of time for children to surf the Internet, and set the account password of internet equipment or install software to limit the time for surfing the Internet; In terms of content, help children find healthy and suitable websites, such as regularly checking the websites that children usually browse, evaluating the contents of websites, or installing parental monitoring tools on the basis of full communication with children; In the aspect of social networking, children are encouraged to explore the new world by using the Internet, but they are firmly opposed to meeting netizens offline, and are informed of the serious danger of this behavior, so as to grasp the real situation of their friends in social accounts at present, and often communicate their online experience with children.

The demand for China’s "gutter oil" is increasing in the United States, Europe and Singapore, mainly for the development of biofuels. However, the global demand for biofuels is huge, and even if all the waste edible oil in China is utilized, it cannot be fully met.

According to the customs data of China, in 2023, China exported more than 2 million tons of waste edible oil, accounting for more than half of the total domestic production, a record high. Since last year, China has become the world’s largest exporter of waste edible oil. From January to July this year, China has exported 1.58 million tons of waste edible oil, an increase from 1.02 million tons in the same period last year. According to a report released by the General Administration of Customs of China, in July, China exported 176,800 tons of waste edible oil, and the main importing countries included the United States, Singapore and Indonesia.

Waste edible oil imported from these countries is mainly used to produce biofuels. Whether it is ester-based biodiesel, hydrocarbon-based biodiesel or sustainable aviation fuel, waste edible oil is a key raw material. Biofuels are favored by countries because of their renewability and environmental friendliness. Waste oils and fats will produce greenhouse gases in the process of natural consumption, but if recycled, it will not only produce economic value but also reduce carbon emissions. For example, the carbon emission reduction effect of ester-based biodiesel is about 60% to 70%, while that of hydrocarbon-based biodiesel can reach about 80%.

The International Air Transport Association requires the aviation industry to achieve zero net carbon emissions by 2050, and stipulates that aircraft should be powered by 100% sustainable aviation fuel, hydrogen or batteries. China’s waste edible oil is exported not only directly, but also in the form of refined biodiesel. In 2023, China’s biodiesel exports to the EU reached an all-time high of 1.8 million tons, of which the Netherlands was the largest importer, followed by Belgium and Spain.
