The new machines in the first half of 2024 have basically been released, and the blockbuster new Huawei Mate 70 series in the second half of the year has been frequently exposed recently, which has attracted great attention from the market. We have also summarized the current valuable exposure information to give friends who follow the Mate 70 series some reference opinions.

In terms of exterior design, the Mate 70 series retains its iconic circular lens module, which has become an important part of the brand’s identity. However, while maintaining its traditional character, the series also cleverly incorporates new design elements that not only enhance the uniqueness of the product, but also give it a more business-like atmosphere.

In terms of screen selection, the Mate70 series provides two different versions to meet the preferences of different users: one is a pure straight screen design, the other is a micro-curved screen design, both of which use a large screen design. It is particularly worth mentioning that the Mate70 Pro adopts advanced zero-hole full screen technology, and through the under-screen camera technology implementation, it not only brings users a more shocking visual experience, but also shows the brand’s unremitting pursuit of technological innovation.

In terms of chip performance, the Mate 70 series is expected to be equipped with a new Kirin chip, which has reached the level of 5nm process technology in performance, indicating a significant improvement and leap in processing power. This advancement will bring users faster running speed and more efficient multi-tasking processing capabilities to meet the demanding performance requirements of high-end users.

In terms of operating systems, the Mate 70 series will run the latest version based on the Hongmeng system, Hongmeng Next. This version of the operating system will not only no longer be compatible with Android applications, but also provide a smoother operating experience and incorporate more intelligent functions to meet the growing expectations of users for smart devices. The introduction of Hongmeng Next will further optimize users’ usage habits and provide more personalized and convenient services.

In terms of photographic capabilities, the Mate70 series is equipped with a domestic one-inch main camera from Howell, which even surpasses the IMX989 in performance in some aspects. In addition, the series is equipped with an OV50K sensor with 50 million pixels, a 1/1.3-inch outsole, and a 1.2μm pixel size. By using TheiaCel technology, the Mate70 series has achieved a significant improvement in dynamic range, enabling it to capture more delicate and rich image details in both well-lit and low-light conditions.

The Mate70 series has achieved a major breakthrough in network connectivity, supporting the latest 5.5G communication technology. The application of this technology allows devices to provide unprecedented network speeds, including downlink speeds of up to 10Gbps and uplink speeds of 1Gbps. This speed not only ensures a smooth experience for users in daily use, but also provides a solid network foundation for high-bandwidth applications such as high-resolution video streaming, large file transfer, etc.

In addition, the Mate70 series will continue to promote the application of satellite communication in communication technology. It is expected that the series will bring more innovation in various fields such as emergency communication. The integration of satellite communication technology provides users with communication solutions without traditional network coverage, enhancing the practicality and security of equipment, especially in remote areas or emergency situations. This function is particularly important.

In terms of battery and charging technology, although the specific battery capacity of the Mate 70 series has not been announced, it can be expected that the series will bring significant battery life optimization. In addition, the Mate 70 series is likely to be equipped with Huawei’s fast charging technology, which will greatly improve charging efficiency, shorten charging time, and provide users with a more convenient charging experience.

In terms of durability, the Mate70 Pro and the Extraordinary Master Edition are expected to use the third-generation Kunlun glass, which is known for its excellent drop resistance and durability. By using this advanced material, the Mate70 Pro and the Extraordinary Master Edition will be able to better resist drops and impacts in daily use, thus prolonging the service life, reducing the need for maintenance, and providing users with a more reliable experience.

According to multiple sources, the release time of the Mate 70 series may be a little later than last year. It is expected that Huawei will officially launch this flagship product between September and October 2024. This timing not only provides Huawei with sufficient time to improve the functions of the product, but also reserves enough expectation and attention for the market and consumers.

In terms of product line layout, the Mate70 series will include at least four models, covering different screen sizes and configuration options. This size strategy is designed to meet the diverse needs of different client bases. Whether it is the entertainment experience of the big screen or the portability of the small screen, the Mate70 series can provide corresponding choices. With a rich product portfolio, Huawei hopes to cover a wider range of markets and meet the needs of different consumers.

　　Recently, the United States and Europe have been arguing about whether and how to provide MIG -29 fighters to Ukraine. First, at the request of the United States, Poland expressed its willingness to send its MiG -29 to the Ramstein Air Force Base in Germany, which was dominated by the United States. The United States quickly stopped it, saying that Poland’s idea was too risky because the United States and NATO tried to avoid a direct conflict with Russia.

　　▲ The first MIG -29 prototype "Blue -01" parked in the Central Air Force Museum of Monino Airport.

　　Obviously, the United States wants to be a "non-stick pot."When MiG -29 takes off from its own base and goes to Ukraine, there is bound to be the risk of retaliation by Russia, so it simply doesn’t take this "dirty job". It is not difficult to see that in the Ukrainian crisis, the United States has been pushing European countries ahead, letting them block bullets and be cannon fodder.

　　Although the United States led European countries to launch verbal attacks and unprecedented sanctions against Russia, it did not consider the safety and interests of European countries.In this "sanction carnival" which was kidnapped by western politics correctly, the interests of Europe were completely betrayed, but many European friends were still ignorant and impassioned.As people who eat melons, I am anxious for them.

　　In this crisis, Europe’s contribution has just begun.

　　First, the European security architecture has collapsed.The geopolitical map of Europe is being rewritten, and the security framework that Europe has been striving for for for 30 years after the Cold War no longer exists. Instead of bringing more security to Europe, NATO has constantly provoked and squeezed Russia into a situation of Jedi counterattack.

　　Since the end of the Cold War, NATO has violated the promise of "never moving an inch eastward" and pushed to the Russian border through five rounds of eastward expansion. Putin said that if ballistic missiles are deployed in Ukraine, they can reach Moscow in seven or eight minutes, and hypersonic missiles only need four or five minutes. This is equivalent to putting the muzzle on someone else’s doorstep. Can Russia bear it? Can you live if you endure it? The answer is no.However, the opening is easy to end. After the United States angered Russia, it put up a "war-free card" and left the rest of the mess to Europe.

　　Second, the economic losses in Europe will gradually emerge.The United States has imposed crazy sanctions on Russia from Europe, from space to aviation, from chips to oil and gas, from financial chain to industrial chain, trying to completely cut off the economic ties between Europe and Russia. In reality, the EU is the largest foreign investor in Russia. In 2019, European direct investment in the Russian market has exceeded 311 billion US dollars. In 2020, the trade volume between Europe and Russia exceeded US$ 174.3 billion. These close and active economic, trade and financial ties have been cut off. How many European enterprises will suffer losses and how many European workers will be forced to lose their jobs?

　　Russia and Europe closed their airspace to each other because of sanctions, and flights from European countries to East Asia had to go around Russia, and the cost increased sharply. The United States has a superior geographical position, but its airlines are little affected. In addition, there are 2 million Ukrainian refugees flooding into Europe, which will also bring a heavy economic burden to European countries and even cause a lot of social problems.We can see that the European people welcome the refugees very touching, but the enthusiasm is temporary after all, and a series of problems caused by refugees have been learned from the past.

　　▲ In October 2015, a large number of refugees from Middle Eastern countries gathered at the border between Slovenia and Austria.

　　Third, Europe’s energy supply is precarious.Affected by the situation in Ukraine, the data of London Intercontinental Exchange (ICE) showed that the European natural gas futures price rose to nearly $3,900/thousand cubic meters on March 7, which was more than ten times the price last spring, while 55% of Germany’s natural gas and 40% of its oil and coal were imported from Russia. Therefore, German Chancellor Angela Scholz still insists on exempting European sanctions on Russian energy under the pressure of the United States and Britain.

　　However, on March 8, US President Biden announced a ban on the import of Russian oil and natural gas. As soon as the voice fell, US Deputy Secretary of State Newland said at a congressional hearing that the "Nord Stream 2" project was dead. This Russian-European joint investment of nearly 10 billion euros in natural gas pipeline was thus lightly sentenced to death by the United States.

　　▲ On March 8, 2022, Biden announced that he would impose an energy embargo on Russia. On the same day, the EU also announced that it would seek to significantly reduce oil and gas imports from Russia. This sanction will push Europe’s energy supply into trouble. (Comic | Liu Rui)

　　European media believe that the Ukrainian crisis will seriously impact European energy supply, and many people will face the choice of starving or freezing this winter and next spring.People of insight in German political circles have publicly stated that "some people say that we are ready to pay a high economic price to get rid of our energy dependence on Russia, but it is the people who pay the price".

　　Sanctions against Russia, the whip also hit Europe.

　　Europe is a mess, and everything goes well in America.The conflict between Russia and Ukraine has made the United States harvest a lot, and many things that we wanted to do before but failed to do have been accomplished: Russia will be difficult to turn over morally or in terms of national strength in the short term, Europe will be more "United", NATO will be more "centripetal", Nord Stream 2 will be terminated, the defense budgets of Germany and many European countries will exceed 2% of GDP, and American oil, natural gas and arms can be sold in the European market.

　　Looking back at the routine of the United States in this crisis, it is roughly fanning the flames before the war breaks out, fearing that the world will not be chaotic, and sending information and weapons after the war breaks out, but insisting that it will never send troops.The wishful thinking of the United States is to let Ukraine bleed, let Europe pay the bill, and let Russia collapse. This is a typical routine of hegemonic logic and the latest application of offshore balance.

　　Does the United States really care about the interests and feelings of Europe? Friends in Europe can recall two things from last year.Last March, at the instigation of the United States, the European Union imposed unilateral sanctions on China on the trumped-up "genocide" in Xinjiang, which was resolutely countered by China, and China-EU Comprehensive Agreement on Investment, which was reached through long and arduous negotiations, was shelved by the European Parliament. Is this in the interest of Europe? No. This is only in the interest of the United States.

　　In September last year, the United States suddenly announced that it would form a trilateral security partnership (AUKUS) with Britain and Australia and would provide nuclear submarines to Australia, openly tearing up the submarine procurement agreement reached between Australia and France and "stabbing" NATO brothers behind their backs. Is this in France’s interest? No. This is only in the interest of the United States.

　　▲ In September 2021, Australia abandoned the submarine project with France since 2016, announced the establishment of a new partnership with the United States, and gave France a hard "backstab".

　　In recent years, French President Macron and other European leaders have loudly called for strengthening the EU’s "strategic autonomy". This is far-sighted, but the key is to realize ideological autonomy independent of the United States.Falling into the American discourse system has made it difficult for many Europeans to see the reality clearly, let alone form an independent strategy. At present, European public opinion is furious, and rational thinking has long been kidnapped by emotion and morality.

　　▲ On February 26th, 2022, the outer wall of the Russian Consulate General in Strasbourg was painted with Nazi symbols.

　　Over the years, the American propaganda machine has continued to "demonize" Russia.In the eyes of the West, Russia is a loser who lost the Cold War and a "second-class citizen" who once wanted to integrate into the West and was rejected. When Biden delivered his State of the Union address, he declared that it was a big tone and a deep prejudice to make Putin an "untouchable" on the world stage.

　　As a result, Russia has been portrayed as a demon hiding in the dark to spy on the West and wait for revenge.All its actions to defend legitimate security interests are regarded as the counterattack of darkness against light and the attack of authoritarian regime on the free world, which naturally deserves worldwide crusade and sanctions.On the other hand, the United States and NATO themselves can hold high the banner of democracy, human rights and freedom and bombard Iraq and turn Syria into rubble.

　　▲ In March 2019, the United States launched an air strike on the town of Bagzi in Syria, killing more than 60 women and children.

　　What about independent thinking and independent judgment of European media? In the information society, if the media have political prejudice and only follow the script obtained from a certain aspect, it will form a wrong public opinion. In the west where votes are paramount, wrong public opinion will form strong public pressure and then kidnap public decision-making. People’s anger is one-sided, rational voices are buried, and government decisions are held hostage. In the long run, there will be no problems.

　　▲ On March 7, 2022, Claire Daley, a member of the European Parliament, questioned at the plenary session of the European Parliament that thousands of Afghans left their homes and sought refuge, but no one mentioned it. Is it just because the invaders are the United States?

　　However, the narrative of American freedom and democracy has come to an end.Under this crisis, the United States and the West have indiscriminately banned Russia in political, economic, cultural, sports, literature and art, education and other fields, and the sanctions against Russia have reached a "new height": permanent neutrality is no longer neutral; The so-called art and sports have no borders, and politics is everywhere; Private property is sacred and inviolable, and can be deprived at will. What about the agreed spirit of contract? The hypocritical rhetoric that the United States has built for so many years has been completely "faced" by itself.

　　In fact, the United States has never given up its own interests because of ideology, because it is only the shell of interests; Europe, on the other hand, is often "not free or give me death", and constantly performs the drama of "losing money and making money" in geopolitics.It should be noted that when people play cards, they will inevitably become cannon fodder.Ukraine is one card, and Europe is another.America is the real super player, smash one, and there is another. As long as the east and west ends of Eurasia never stop, the hegemony will sit firmly. We would like to invite European friends to think together. Is the Russian-Ukrainian conflict a "self-fulfilling prophecy" or an elaborate strategy?

　　Man learns truth at the expense of suffering. What can we learn from the Ukrainian crisis?

　　The serious lack of mutual trust among major powers has led to the return of geopolitical conflicts.There is no mutual respect and basic trust between big countries, and in the end it is a war against each other.China’s philosophy says "extremes meet", and the result of one-sided pursuit of maximizing security interests is the collapse of the security system, which makes everyone unsafe.

　　Since the end of last year, Russia has also tried to solve its core security concerns through negotiations with the United States, and the response is only arrogance and perfunctory, leaving Russia with only "dealing with the jungle law with the jungle law." Two days ago, Putin quoted Catherine II as saying, "As long as I have enough life, I will defend my motherland with words, pens and swords."

　　When the security interests and national dignity of a big country are trampled on wantonly, it is the moment when war comes.Some people exclaim that traditional geopolitics has returned, and great power confrontation has returned. Who is the initiator? Can only blame the cold war mentality, hegemonic countries.

　　Pushing Russia into a desperate situation is a historic failure of the West and a tragedy of Europe.The United States can still watch the fire from the other side of the bank, and even provide MIG -29 fighters to Ukraine with fake hands in Poland. And where can Europe hide? There is only so much room in Europe. After the war, the distance between Berlin and Moscow is still 1600 kilometers. European countries will still live on the same continent as Russia and re-explore the possibility of building a security architecture. And why can’t all this start before the conflict breaks out?

　　▲ In the eyes of the United States, Europe is just a "marionette" manipulated to safeguard its hegemony and interests. (Comic | Liu Rui)

　　Maintaining hegemonic status is the core of American foreign policy, and we can do whatever it takes to achieve this goal.Europe is an important pole in the multi-polarization of the world and an important force to promote the democratization of international relations. It should seek and adhere to strategic autonomy in all fields and not act as cannon fodder for the United States to safeguard its hegemonic "cause".

　　Life newspaper May 19 th The wild Siberian tiger was first discovered in China on May 20 last year, and it has been occupied by Raohe County and surrounding forest farms for a whole year. Experts say that in its mind, this area is its territory. It used to be just a transit, and there is no sign of leaving this year. The natural environment in our province is improving, which provides a broad living space for the Northeast Tiger. Moreover, this Northeast Tiger is a "foodie". According to the statistics so far, it has eaten five roe deer, two wild boars and a cow.

　　According to Sun Chengfu, director of the Wildlife Protection Office of Raohe Forestry Bureau, after follow-up research, DNA identification and behavioral research, it has been confirmed that this tiger has settled in our province, but it is not the only one that is hard to say, because there are reports of activities of the Northeast Tiger in other forest areas.

　　　What did you do this year?

　　　1. A large number of claw marks were found on the trunk of contiguous forest land.

　　"This tiger has formed a fixed territorial scope, showing a specific demarcation behavior of wild animals." Sun Chengfu said. The territory of the wild Siberian tiger is about 1000 square kilometers for males. The contiguous forest land here is suitable for the Siberian tiger to settle down, and its forest area is close to 1000 square kilometers.

　　"When the Northeast Tiger takes a fancy to a place, it will leave paw marks on the tree and mark the boundary with urine. If there are these marks, other tigers will not invade without authorization." Sun Chengfu said that they found a lot of claw marks on the thick trunk of the territory boundary, which is called "hanging claws", and urine was collected in winter.

　　　It has been found to have eaten five roe deer, two wild boars and a cow.

　　On December 12 last year, Sun Chengfu and his colleagues took more than 100 photos of the Northeast Tiger eating cattle with a far-infrared camera, which is quite precious. On the same day, they received a report from the villagers that his old cow might have been attacked by the Northeast Tiger. Sun Chengfu rushed to the scene and found that the cow was eaten by a third of the tiger. More than 200 kilograms of adult cattle, the Siberian tiger killed it effortlessly, and dragged the body for hundreds of meters, hiding it in a deep ditch on the edge of the corn field. Sun Chengfu judged that the tiger would come back if the beef was not finished, so he arranged the shooting equipment nearby. Sure enough, the next day, the Siberian tiger returned to the scene and moved the beef to eat again.

　　Sun Chengfu said: "From the photos, this Siberian tiger is strong and well-nourished, indicating that there is enough food. According to statistics so far, it has eaten five roe deer, two wild boars and one cow. "

　　I went back to Russia to "find someone" and came back two months later.

　　This tiger went back to Russia once, and Sun Chengfu speculated that it was going back to "find an object". In the middle of December last year, during the patrol, Sun Chengfu found that the tiger trail extended to the Sino-Russian border. He tracked it for more than 20 kilometers and found that the tiger trail crossed the center line of the main channel of the Wusuli River and disappeared on the Russian side.

　　Two months later, the Northeast Tiger returned to the territory of Raohe County. Sun Chengfu said: "After mating, the Northeast tiger went back to its territory, and this tiger returned to China, which once again proved that it had settled in our province."

　　　4. I once strolled to the human activity area, 10 meters away from the fishing room.

　　"Leave as soon as possible in case of the remains left by tigers. Maybe the Northeast Tiger is not far away." According to reports, this Siberian tiger is not afraid of people, and it has been recorded in the vicinity of human activities. The last time it was 10 meters away from the fishing house by the river. On the 16th, Raohe Forestry Bureau issued an announcement to remind the general public, "Don’t enter the mountain at will for personal safety". According to reports, local residents generally walk together in the mountains, carrying firecrackers with them, driving tigers away with firecrackers, and trying to stay away from the Northeast Tiger activity area.

　　First discovery: May 20th last year.

　　A five-or six-year-old male adult tiger left a trail of footprints in farmland.

　　Raohe County is located in the northeastern border of our province, with a border line of 128 kilometers and a forest coverage rate of 51%. This area is one of the important corridors and activity areas for Siberian tigers to enter China from Russia. In recent years, many Siberian tigers have been active in the forestry application area here.

　　"This Siberian tiger was first discovered on May 20 last year. From this day, it has been here for one year." Sun Chengfu said.

　　Last year, a series of footprints left by the Northeast Tiger in the farmland exposed its whereabouts. "At that time, experts from the Cat Research Center of Northeast Forestry University happened to be investigating in Raohe River. After discovering the paw prints, the experts unanimously concluded that it was the footprints of the Northeast Tiger. Through the size and depth, the experts thought it was a male adult tiger, and the tiger was five or six years old." Sun Chengfu said.

　　Goodbye tiger trail: March 1 this year

　　The feces of Amur tiger collected again are the same as before.

　　The local animal protection staff conducted a follow-up study. In addition to taking photos and infrared cameras, they also collected the feces of Siberian tigers many times. On March 1, 2018, the tiger trail was found again in Shiye District of Tonghe Forest Farm. After 7 days of tracking, the wildlife department of Forestry Bureau collected the feces of the Northeast Tiger again and sent it to Northeast Forestry University for DNA identification. Compared with the previous feces, it was judged to be the same tiger.

　　Video tiger: April 23 this year

　　20 pairs of far-infrared devices captured 3 seconds of video.

　　Sun Chengfu said that 20 pairs of far-infrared camera equipment have been put into the territory of the Northeast Tiger, each pair of equipment includes a camera and a video camera, 10 warning signs have been set up in key activity areas, and 14 patrolmen are responsible for the protection and investigation of the Northeast Tiger. At 3 o’clock in the morning of April 23 this year, infrared camera equipment captured a 3-second video of the Northeast Tiger. The video shows that this Siberian tiger walked deep into the jungle through the forest road. This is the only video of this Siberian tiger.

　　Recent trail: May 10th this year.

　　I enjoyed another wild boar more than a week ago.

　　Sun Chengfu said that on May 10 this year, it was the last time they photographed the trail of this wild Siberian tiger. A wild boar killed by it had been hollowed out. "The pork hasn’t had time to eat, which means it may be not far away, so I only took a photo at that time and immediately evacuated."

Today, let’s take a look AT the AT gearbox and the dual clutch gearbox, which one should we choose? Please see next.

AT gearbox:Variable speed is realized by hydraulic torque converter and planetary gear set. Hydraulic torque converter uses liquid to transmit power, which can cushion the power impact of the engine; Planetary gear sets realize different transmission ratios according to different combinations.

dualclutchtransmissionThe odd and even gears are controlled by two clutches, which is equivalent to integrating two sets of manual gearboxes. When shifting gears, prepare the next gear in advance to realize fast shifting.

Shift speed: the shift speed of dual clutch gearbox is extremely fast, usually only about 0.2 seconds, while AT gearbox is relatively slow.

Transmission efficiency: the transmission efficiency of dual-clutch gearbox is high, and the power loss is small, which can generally reach about 85%-90%; The transmission efficiency of AT gearbox is relatively low, about 70%-85%.

Driving experience: the dual-clutch gearbox is more direct and neat when shifting gears, which can bring better driving pleasure, but it may have a sense of frustration when driving at low speed; The shift of AT gearbox is relatively smooth and comfortable, but the dynamic response may not be as direct as that of dual clutch gearbox.

Structural complexity: AT gearbox has a complex structure, including hydraulic torque converter, planetary gear set and other components; The structure of dual clutch gearbox is relatively simple, similar to manual gearbox.

Cost: Generally speaking, the manufacturing cost of AT gearbox is high, especially the high-end AT gearbox; The cost of dual clutch gearbox is relatively low, especially dry dual clutch.

Good ride comfort: the existence of hydraulic torque converter makes the shift process softer, the shift feeling is obvious and the driving comfort is high.

Large torque bearing: able to bear large engine torque output, suitable for all types of vehicles, including high performance and large vehicles.

Mature technology: it has a long history of development, relatively mature and stable technology, high reliability and low failure rate.

Simple operation: the driver only needs to control the throttle and brake, and there is no need to manually shift gears, so the operation is simple and easy.

Disadvantages:

Low transmission efficiency: power will be lost in the transmission process, resulting in relatively poor fuel economy.

Complicated structure: The complicated structure makes AT gearbox bulky, heavy and costly to manufacture.

Slow shift speed: compared with the dual clutch gearbox, the shift speed is not fast enough, which affects the dynamic response and acceleration performance of the vehicle to some extent.

High fuel consumption: Due to the low transmission efficiency and its own structural characteristics, the fuel consumption of AT gearbox vehicles is relatively high.

Fast shift speed: it can complete the shift operation in a very short time, and the power interruption time is short, which can provide better acceleration performance and driving experience.

High transmission efficiency: direct power transmission reduces energy loss and improves fuel economy, especially at high speed.

Simple structure: Compared with AT gearbox, it is relatively simple in structure, small in size and light in weight, and easy to install and arrange on vehicles.

Low cost: the manufacturing cost is relatively low, which helps to reduce the price of the whole vehicle.

Disadvantages:

Low-speed setback: Under low-speed driving, frequent start-stop or congested road conditions, there may be setbacks, which will affect driving comfort.

Reliability problem: There were some reliability problems in the early dual-clutch gearbox, such as clutch overheating and wear, but with the continuous improvement of technology, the reliability has been greatly improved.

High heat dissipation requirements: especially for dry dual-clutch gearbox, because there is no oil immersion to dissipate heat, long-term intense driving or frequent gear shifting will easily lead to overheating, which will affect performance and life. The wet dual-clutch gearbox dissipates heat through oil, which is relatively good, but the cost is high.

High maintenance cost: The clutch plates and other parts of the dual-clutch gearbox are vulnerable parts, which may need to be replaced after a certain mileage, which increases the maintenance cost.

So, friends, which gearbox do you prefer?

According to chengdu research base of giant panda official micro-news, recently, under the constant popularization of science and guidance of the panda base, media, caring people and fans, the tour order of the park has gradually become orderly. We are deeply grateful for the pertinent suggestions and help from people from all walks of life! However, during the tour of the panda base,It is still found that some tourists have uncivilized behavior, which is now reported as follows.

Yao Moumou (female, 47 years old), born on April 11, 2023.Throw things into animal houses and other places in the park., destroying the environment, violating the relevant regulations of the panda base for the first time, and has signed a written commitment letter for civilized visit.

Li Moumou (male, 41 years old) was in the park on March 27, 2023.Conduct live webcasts,For the first time, I violated the relevant regulations of the Panda Base and signed a written commitment letter for civilized visit.

Yi Moumou (female, 47 years old), since April 11, 2023.Distribute leaflets in violation of regulations in the park,For the first time, I violated the relevant regulations of the Panda Base and signed a written commitment letter for civilized visit.

Here, Pangda advocates that all tourists and friends practice civilized conventions during the visit, obey the arrangement of the on-site staff and work together to protect the cute giant panda.

For these uncivilized tourists,

Netizens are angry:

Heavy penalty, blacklisted

　　Xinhua News Agency, Chengdu, April 6 (Reporter Yu Li, Feng Changyong) The reporter learned from the China Giant Panda Conservation and Research Center, which has the largest captive giant panda population in the world, that the center has completed nearly half of the breeding and breeding tasks of captive giant pandas this year, and the giant panda breeding has entered a peak period.

　　By the end of 2015, the number of captive giant pandas in the center had reached 218. Zhang Guiquan, director of Ya ‘an Base of China Giant Panda Conservation and Research Center, said that this year, 26 female pandas and 19 male pandas participated in the national captive giant panda breeding program. Since the first female panda was bred in late February, as of April 6, 10 female pandas have been bred. Among them, 6 were bred by natural mating, the other 2 were bred by natural mating with artificial insemination, and the remaining 2 were completely artificially inseminated.

　　"So far, this year’s breeding work has been completed well. The biggest feature is that the natural mating rate is relatively high, and the pregnancy rate of female pandas that have successfully mated naturally is over 90%, which is a good momentum for this year’s breeding work." Zhang Guiquan said.

　　"Under the current captive conditions, the number of male giant pandas with natural mating ability is very rare, accounting for less than 5% of the population. This year, the center belongs to the 7-year-old male giant panda ‘ An An ’ The first successful natural mating at Ya ‘an base on February 29th marks the addition of a male animal with natural mating ability to the captive giant panda population, which also shows that the quality of our captive giant panda population is constantly improving. " Zhang Guiquan said.

　　According to reports, at present, the artificial breeding of captive giant pandas in China is included in the unified planning, and the optimal pairing is carried out according to the principle of eugenics, so as to ensure the genetic diversity of the population to the greatest extent. There are 56 female pandas participating in the breeding program this year, and more than one third of them are from the China Research Center for the Protection of Giant Pandas.

　　There are three major problems in the development of captive giant panda population: difficulty in estrus, difficulty in mating and conception, and difficulty in survival of cubs. According to zhangxin, the breeder of the center, giant pandas are in estrus every spring. With the increase of temperature, their hormone level, estrus behavior and mating desire will decrease from May, which will affect the mating quality. Therefore, March and April are the prime time for giant pandas to breed. In order to ensure that female pandas are pregnant, some will also receive artificial insemination as appropriate after natural mating.

　　In recent years, the artificial breeding of giant pandas in the center has been carried out at Bifengxia base in Ya ‘an. The reporter saw at the base on the 6th that the staff was preparing to breed the 7-year-old female panda "Jojo". Because Jojo’s estrus behavior was not typical enough, she was not allowed to mate naturally. In this regard, Zhang Guiquan said that this is a normal situation.

　　It is reported that female giant pandas not only have a short estrus time, but also need to mate with each other to be successful. If there is no electricity between pandas, mating may fail even during estrus. In addition, even if natural mating is successful, it is very difficult for female giant pandas to finally give birth to panda babies — — Their eggs can only survive for 36 to 40 hours. Even with breeding, only 30% to 40% of female giant pandas can get pregnant successfully, while the survival rate of their cubs is less than 40%.
