Some people say that the standard to measure a person’s driving skills is not how much the highest speed can be driven, but whether he can stop the car at a critical moment! It can be seen that the importance of automobile braking system.

Brake oil, brake pads and brake discs are the only things that need to be replaced frequently in the brake system of a car. Today, Lao Yang will talk about what brake oil is, how to replace it and how long to replace it.

1. What is brake oil?

As we all know, cars nowadays are all hydraulic braking systems. When we step on the brake pedal, we can increase the braking force through the booster pump. The brake master cylinder will pump the brake oil out of the oil pot, and the control valve will distribute the brake oil to the brake cylinders of each brake pipe. After that, the brake oil will push the pistons in the brake cylinders to make the brake pads and brake discs rub. This is the braking principle. If you still don’t understand, you can think about the working principle of the needle tube used for infusion when you were a child.

Second, why should I change the brake oil?

Above know the importance of brake oil, let’s talk about the characteristics of brake oil. Because brake oil works frequently, its stability is better, and it has to withstand the influence of high temperature, and its boiling point is relatively high, otherwise it will boil when it brakes violently, which will affect the braking distance.

The most important point is that brake oil is different from other oils. It has water absorption and may be mixed with water after a long time, which will have an impact.

You might say, why is there water?

Well, the volume of brake oil will change with the change of temperature, so there is a vent hole on the brake oil storage pot. The air sucked from this hole contains moisture or impurities, and the moisture will be absorbed or dissolved by the brake fluid. Once this happens, the braking distance will be extended, causing the brakes to become soft.

3. How long does it take to change the brake oil?

According to the requirements of the manual, the general brake oil requires 20-40 thousand kilometers to be replaced, and different models are different. According to the maintenance cycle of personal driving, it is recommended to change the brake oil every 30 thousand kilometers, and it is best to check it with the brake pads. After all, the brake system is very important.

Finally, the choice of brand, we must pay attention to the brake oil model when changing the brake oil. Generally, vehicle brake fluid is classified by DOT. According to the regulations of american petroleum institute, brake fluid is divided into DOT3, DOT4 and DOT5.1. Therefore, it is necessary to avoid the reaction caused by mixing brake oil.

Secondly, for brands, such as Shell, Mobil and Bosch, if you don’t understand, you can add universal brake oil in 4S shop.

That oil is also the oil that cars often need to change. What should we pay attention to and what is its classification? You can reply in the background of WeChat WeChat official account."engine oil"Two words to check.

　　CCTV News:This year’s National Day holiday, a small town tour with complete facilities, a special regional cultural tour and a city outing have become new choices for tourists to travel. Punching in the ancient town of the city and wandering in the suburban flower sea has become a new business card for this year’s National Day holiday.

　　Yanshen Ancient Town, located in Boshan District, Zibo City, Shandong Province, ushered in the first holiday after the opening of the park. Since the Northern Song Dynasty, Yanshen Ancient Town has become a market town with ceramic workshops as the core, with many ceramic and glass craftsmen gathered. At present, the ancient town still retains 13 ancient kilns and ancient buildings in Ming and Qing dynasties, which has become a unique historical element to attract tourists. The data shows that six days before the National Day holiday, the ancient town received more than 20,000 tourists and achieved sales income of more than 500,000 yuan, of which tourists from the province accounted for 85%.

　　This holiday, full of national culture with regional characteristics, also allows consumers to immerse themselves in the charm of culture. In Shenmu Village, Xiqiang, Tongquan Town, Beichuan Qiang Autonomous County, Mianyang City, Sichuan Province, the ancient and mysterious ceremony of entering the village ushered in waves of tourists from surrounding cities and counties. Accompanied by the joyful drums, the children of the Qiang people respect the tourists and put on Qiang red, and invite them to dance with dragons and shalang, so that they can feel the charm of Qiang culture while singing and dancing.

　　The lively atmosphere of the event not only made tourists happy, but also ignited their passion for consumption. While enjoying the Qiang culture, tourists also walked into the Qiang non-legacy straw weaving workshop and participated in the production of straw weaving. There are no fewer than 200 tourists who participate in the production and purchase of cultural and creative products like this every day. According to the data released by the Sichuan Provincial Department of Culture and Tourism, compared with this year’s Mid-Autumn Festival, the cumulative reception and ticket revenue of scenic spots in the three days before the National Day increased by 318% and 632% respectively. Libraries, cultural centers and museums in the province have received a total of 890,000 people.

　　In addition to punching in the ancient town of the city, in the autumn season, outdoor suburban flower viewing also makes this holiday full of color. Sunflowers in Nanjing Zhangxukui Flower Garden are in full bloom. The golden disk is facing the sun, blooming brilliantly, the autumn wind blowing and dancing lightly.

　　As of October 6th, Zhangweikui Flower Garden had received about 180,000 tourists, up 28.3% year-on-year. The total tourism revenue was about 1.207 million yuan, a year-on-year increase of 27.8%. According to the data of the travel platform, during this holiday, more passengers locked their destinations in the unpopular "small town tour", avoiding passenger flow, reducing queues and reducing risks, which became the most popular reason. In addition, the data also shows that the booking volume of four-star and five-star hotels in some niche destination cities has increased significantly compared with the same period in 2021. Sanming, Fujian increased by nearly 20 times, Jieyang, Guangdong increased by 1.5 times, Yiyang, Hunan increased by 1.2 times, and Xuchang, Henan increased by nearly 1 time.

　　The British government and the European Commission recently issued a joint statement saying that Britain will return to the EU’s flagship scientific projects "Horizon Europe" and "Copernicus" Earth observation projects through a new agreement with the EU. This move was welcomed by the scientific circles of both sides and regarded as an important moment to restore trust between the two sides. However, for the British scientific community, returning to the project cannot recover the losses that have been caused.

　　Horizon Europe is one of the largest multilateral research projects in the world.

　　Before Brexit, the British scientific community was one of the main beneficiaries of the Horizon Europe project, and scientists were eligible to apply for funds underwritten by the British government. However, after Britain’s "Brexit", many cooperation was forced to stop.

　　According to data from the European Commission, since 2019, funding for British science projects has fallen sharply. In that year, 959.3 million euros went to 1,364 research projects in the UK, while in 2023, only 192 grants were approved, totaling only 22.18 million euros.

　　After arduous negotiations, the British Prime Minister’s Office recently issued a statement saying that Britain has finally reached an agreement with the EU to rejoin the EU’s flagship scientific project — — Horizon Europe.

　　According to the latest agreement, British researchers can resume applying for the project funds of Horizon Europe and participate in related research from now on. From 2024, British scientists will be able to fully participate in the "Horizon Europe" project like scientists from EU member States. As an "associate" member during the implementation period from 2021 to 2027, the UK has to pay 2.6 billion euros every year.

　　As part of the UK-Europe Trade Cooperation Agreement in 2020, the UK had negotiated the associate membership of Horizon project, but due to the protracted dispute over the trade rules in Northern Ireland, the UK could not start the project.

　　Earlier this year, after several months of talks, British Prime Minister Sunak and European Commission President Ursula von der Leyen finally reached an agreement at Windsor Castle, in order to resolve the controversial dispute over Northern Ireland’s trade rules since Britain’s formal "Brexit" in 2020, and realize the smooth trade of the whole UK. Sunak said at the press conference that Britain and Europe have made a decisive breakthrough, and the "Windsor Framework" has opened a "new chapter" in British-European relations.

　　The latest agreement on return is regarded as another important symbol of the breakthrough in the relationship between Britain and the European Union. The agreement was warmly welcomed by the British scientific community, and the British Minister of Science, Innovation and Technology, Michelle Tang Lan, said on the same day that the agreement was a key step on the road of British scientific and technological development. European academic circles also welcome this.

　　In addition to the Horizon Europe project, Britain will rejoin the European Union’s Copernicus project, which uses satellites to monitor the impact of climate change on the earth and is very important for analyzing extreme weather events.

　　However, the agreement between Britain and the European Union also sets a threshold to limit the amount of funds available to British researchers. If the amount of project grants received by British researchers for two consecutive years is more than 8% higher than the amount paid by Britain, the British government must make up for the excess. On the contrary, if the British scientists receive less funding than the amount paid by the British government to the Horizon Europe project, the British government will be compensated. This threshold is only for the UK, not for EU member states.

　　Although Britain was able to return to the Horizon Europe project and Copernicus project, many scientists said that the loss brought to the British scientific community by the interruption of cooperation for two years was irreversible.

　　As a member of the European Union, due to the strong financial support of British universities, Britain usually gets more funds from the Horizon project than its contribution, but as an associate member, this situation is excluded.

From Johns Hopkins Hospital to xuanwu hospital of Capital Medical University, from an excellent medical expert to an outstanding academic leader; For the first time more than ten years ago, he represented the cutting-edge technology of functional encephalopathy treatment.The technology of "Cell Knife" was introduced from the United States to China, which greatly improved the efficiency of surgical treatment of Parkinson’s disease. After the magical "Cell Knife" treatment, the muscles of thousands of patients in China stopped shaking and stiff, and their lost ability to live and work was restored.

He is Li Yongjie, director of functional neurosurgery at xuanwu hospital of Capital Medical University, with China on his head.The halo of the first person in the "cell knife" should be refined into a "scientist doctor".

Go out and see different scenery.

Li Yongjie was born in last century.60An intellectual family in the s.1979In 2008, my mother said, "It would be nice to have a doctor in our family, so you should study medicine!" " Let Li Yongjie accompany medicine for a lifetime.. heTake the first place in the school and get into Beijing Medical College.,After graduation, he chose to study under the famous neurophysiologist Professor Qiao Jiantian for postgraduate study.1991In 2000, he got a doctor’s degree in medicine and stayed in the affiliated hospital of Shanxi Medical University.

Everything seems to settle down in this way, but the more professional knowledge grows, the more clearly Li Yongjie feels that his vision is narrow. Can’t persuade to give up the dream that I haven’t forgotten in my heart.— — When going abroad, you should go out and feel the different scenery outside.1994In the summer of 2008, Li Yongjie came to the Department of Neurosurgery of Johns Hopkins Hospital to do postdoctoral research. Here, Li Yongjie approached the international forefront of microelectrode-guided stereotactic neurosurgery at that time, and the stable, long-term and immediate surgical effect deeply attracted him.

He still clearly remembers a female patient with primary tremor from Maryland. It was a thalamototomy that day. After the brain was accurately located, the damage began. Within a few seconds, the severe tremor of the patient’s right hand disappeared. When Li Yongjie asked her how she felt, she didn’t say a word, staring at her hand for a long time, and her eyes suddenly burst into tears:“ oh,it stopped. Look,after 10 years! Oh,my God! "(Oh, it stopped.10Years, my god.!）。 That is, from then on, Li Yongjie realized that his attention and interest were converging on stereotactic technology.

In those days, he was fascinated by reading monographs and documents on stereotactic neurosurgery and devoted more and more energy to clinic. Every operation day, it must besixGet up at 8 o’clock, he eats breakfast while driving, in the morning.sevenArrive at the hospital before o’clock.CTRoom. As soon as the patient arrives, help to install the stereotactic headstock and observe it.CTPositioning, and then aboutfive～sixIntraoperative electrophysiological function localization in hours. In addition, Li Yongjie also tried his best to find time to go to the ward to observe the patients after operation, and to understand the relationship between the surgical effect and the accuracy of intraoperative positioning, as well as the direction of improvement in the future … … Do these "extra jobs" wholeheartedly.

1995yearthreeIn May, Li Yongjie stared at the world-famous California through the pictures broadcast on TV.Loma LindaNeurosurgeon, University Medical CenterRobert 　P．IaconoThe professor operated on a patient with Parkinson’s disease with a "cell knife". With his skills in neurophysiology, Li Yongjie noticed a detail on the TV screen — — Intraoperative electrical signal noise is too high. Li Yongjie concluded that the setting of electrophysiological system may be unreasonable, which is not suitable for the operating room environment interfered by high-frequency electrotome and needs better shielding. That night, he wrote toIaconoProfessor, frankly talked about his views on technical improvement. This bold move has caused Li Yongjie toIaconoThe professor’s attention, quickly replied to his letter, and sent a job invitation. Li Yongjie finished his postdoctoral study ahead of schedule with excellent results, and shouldLoma LindaThe invitation of the University Medical Center came from Maryland on the east coast of the United States to Southern California on the west coast, and devoted himself wholeheartedly to clinical treatment.

In this way, Li Yongjie approached the international forefront of microelectrode-guided stereotactic neurosurgery at that time, commonly known as"Cell knife" technology. He was deeply shocked and impressed by the "cell knife" when he witnessed countless successful operations and witnessed too many Parkinson’s patients who stood up again from their wheelchairs.

Return to the motherland to sow the ideal seeds

At the beginning of coming to the United States, Li Yongjie’s goal was to be a neurosurgeon. Because in the research of basic medicine, China has not been able to keep up with the advanced level in the world in many aspects, and he hopes that he can do his bit to change this situation. But withWith the application of "Cell Knife", Li Yongjie found that since the advanced technology was in front of him, wouldn’t it be a more effective shortcut if he could master it and use it to serve the motherland?

1998In, Li Yongjie resolutely returned to China. Speaking of this work for more than 10 years, Li Yongjie smiled faintly. "Cell knife was only a few years ago, and we have already begun to use more cutting-edge technical means to treat more diseases." Li Yongjie is constantly thinking about the way forward: China has introduced many advanced technologies from the world, but after a period of time, it has been left behind by the world. The reason is very simple. Without the corresponding mechanism of technological innovation and progress, the old capital of advanced technology has been eaten up, and naturally it has fallen behind.

Parkinson’s article"Fish" will be eaten up one day, and it is necessary to weave a net for "fishing". The surgical treatment of Parkinson’s disease is not limited to pallidotomy and thalamototomy, and the indications of surgical techniques are not limited to Parkinson’s disease, a movement disorder. Li Yongjie’s goal for himself is to be a scientist-type doctor: "Not a simple doctor, but to do research and innovation, to have a scientist’s mind, and what he makes is not commonplace".

Building "China Team" of Functional Neurosurgery

Among many patients, there are countless families who have traveled all over the country to see their families. Every time I meet such a doctor, Li Yongjie’s heart is very heavy. After several considerations, Li Yongjie put forwardThe concept of "terminal". "I hope I can tell patients not to go to the hospital in a hurry. It can’t be solved here, and there will be no better way elsewhere." Li Yongjie hopes to give these patients a belief and make them feel more at ease. Li Yongjie knows very well in his heart that if patients and even colleagues really agree with their concept of "terminal station", they must expand the connotation and extension of functional neurosurgery and weave the net of "fishing" bigger and denser.　

Li Yongjie led his team to keep track of the latest development of functional encephalopathy in the world, improve technical methods, improve the level of treatment and expand the scope of treatment.1999yearthreeIn May, the Institute of Functional Neurosurgery successfully treated Parkinson’s disease with subthalamic nucleus destruction technology, and in the same year, it also developed deep brain stimulation technology (brain pacemaker therapy) to treat Parkinson’s disease.1999yearfiveIn June, the first operation of generalized torsion spasm was successful.1999In the second half of 2006, the first operation of spastic torticollis, chorea and Tourette’s syndrome was successful one after another.

After creatively expanding the scope of surgical treatment to other dyskinesia diseases, Li Yongjie began the work of surgical treatment of epilepsy and pain, which has been extended to.30A variety of functional encephalopathy. With the increasing fame, Li Yongjie’s concept of "terminal" has been recognized by more and more people, and there are countless patients who come here.

Zhang Guizhong is a patient with Parkinson’s disease.11In 2000, he always relied on drugs to control his illness, but with the development of his illness, his trembling became more and more serious and he could not take care of himself. The side effects of drugs are getting bigger and bigger, and he can only stay in bed after taking drugs. The son who joined the army was forced to leave the army and go home to take care of his father. Director Li Yongjie performed deep brain stimulation surgery for him, successfully implanted a brain pacemaker, and his condition was well controlled. When Zhang Guizhong, who had been trembling for many years, walked out of the ward smoothly, his family shed tears of joy.

Now,The more patients are treated, the more Li Yongjie feels that even if he has great skills, the number of people who can be treated is extremely limited. Only by creating a world-class functional neurosurgery."China Team" can benefit more patients. So he focused on building a world-class functional neurosurgery "China Team". When he chooses a "team player", he has a high demand for character. "The most fundamental thing is that he must be a good man, be honest and have a good view of right and wrong. Without kindness, he will not treat his colleagues and patients well; Without cooperation and integrity, there will be no team spirit. "

Li Yongjie said that to be a trustworthy doctor, the first thing is"Benevolent people love others" and have a heart of kindness. He often tells himself to be in awe of the brain tissue that has evolved under the scalpel for millions of years. Over the years, he and his team have worked hard to create and practice this concept, so that patients can get world-class treatment, the most humanized service and the most determined psychological support.

At present,functional neurosurgeryalreadyIt has mushroomed in major hospitals all over the country, benefiting many patients with functional diseases of nervous system, and making functional neurosurgery take root in China, keeping pace with the world and even surpassing the world’s development level.

1905 movie network news　A few days ago, the film was officially scheduled for December 16th and will be released simultaneously with North America. The film was created by the director after 13 years of hard work. On December 8th, the film released the dubbing lineup, inviting He and his wife to join forces for the first time as the soul of the film, Jack Sally and Neytiri, to lead the audience back to Pandora and start a new adventure. The powerful actors who have won many awards and nominations will dub the new leader of the island people, Tenowari, to play the role of the strong and brave Neville leader. More importantly, the female leader of the island people played in the film, Ronal, will be played by an internationally renowned Chinese actor as the Chinese voice actor.

The posters released at the same time match the four movie stars with their "voice" characters one by one. On one side is the "Avatar: The Way of Water" character poster, and on the other side is the photo blockbuster of four Chinese voice actors. Challenging the new limits of film art and creating an immersive feast of light and shadow, the ultra-luxurious voice cast makes fans look forward to the film’s release even more.

Jack Sally and Neytiri, the soul characters of the series that have touched the heartstrings of countless audiences in the past 13 years, are specially invited to offer the voice dubbing of Deng Chao and Sun Li, who are also highly regarded in the Chinese film and television industry. As powerful actors who have collected major awards in the Chinese film and television industry and have great reputation and other influences, Deng Chao and Sun Li are also famous model couples in the circle. This time, the film side invited the two to join the dubbing. In addition to professional ability, they also want to use the screen images of the two in real life to better appreciate the sequel and resonate with the characters.

As the soul characters of the "Avatar" series, Jack and Neytiri have formed a family and become parents in the sequel. They will once again take on the heavy responsibility of saving the planet Pandora, and the bond between the tribe and the love for their family is the source of their strong will and courage. And such a character setting is undoubtedly highly compatible with the identities of Deng Chao and Sun Li. From voice expression, professional image, to real life perfect match, Deng Chao Sun Li will bring his own feelings about life, children and family to interpret the sequel of Jack and Neytiri.

In addition to past roles, this sequel will also include a new character, Tenowari, the leader of the island reef clan, whose voice is played by young actor Huang Xuan, which is surprising. With past excellent works such as "Mountain and Sea Love", Huang Xuan stands out. He has been nominated for the male lead in the Magnolia, Feitian and Golden Eagle TV Drama Awards at the same time. He has become a leader among the new generation of actors. He is a rare force and acting style among young actors. Every time he acts, Huang Xuan will devote himself wholeheartedly. Not only is his voice full of magnetism and his lines cadence, but his rich emotions are also very infectious.

This time, Huang Xuan will be the voice of Tenowari, the leader of the island reef tribe. Tenowari is fair but generous, reaching out to the Jack family when they are in danger and allowing them to take refuge in their tribe. As a leader, he is full of majesty, as a soldier, he is determined and brave, which also fits well with many of the roles played by Huang Xuan before. Whether it is from the details of the dubbing or the expression of emotion, this time Huang Xuan will use the charm of the voice to bring you a unique interpretation and explore the mysterious new sea.

"Card God" took 13 years to continue writing the legend, and a stunning new character was introduced. Ronal is not only the wife of Tenowari, the leader of the reef clan, but also the brave and fearless mother. She is also the spiritual leader and high priest of the reef clan. This time, Cameron director invited Oscar winner Kate Winslet to play the role, and Ronal’s Chinese voice is invited to Zhang Ziyi, who is famous in the international film industry for his masterpieces.

As the spiritual leader of the Islanders, Lorna is authoritative and powerful, and she has shown the most heroic and fearless posture. This role is highly compatible with the identities of Hollywood actress Kate Winslet and Chinese actress Zhang Ziyi. With her outstanding film works known at home and abroad, Zhang Ziyi is not only a Grand Slam winner of Chinese film awards, but also starred in many works that have won Oscars and multiple international film festivals. She has also been nominated for the Golden Globe Award in American Film and the British Film Academy Award for Best Actress. She is a Chinese actress who is well-known in the international film industry. This time, she "vocally" portrays the tough, fearless, tough and flexible Lorna, leading the audience into a new realm of legend.

Original title: Authoritative release: Kydroid OS & Android are really compatible!

Recently, Tianjin Kirin Information Technology Co., Ltd. and the R & D team of National University of Defense Technology officially announced that the Android compatibility project Kydroid has completed the first phase of research and development, and can achieve compatible operation of most Android applications by building an efficient running environment on the Kydroid operating system. From now on, some applications on Android can run directly on the Kydroid system! Friends no longer have to worry about no games to play, no QQ use, and no stock speculation under the domestic Linux system!

If you are tired of writing code, you can play games!

Write documents tired can look at the stock information!

Browse a web and QQ more convenient!

High execution efficiency, smooth running, you can install your favorite Android applications as needed! And support one-click installation of APK packages!

Such an artifact is definitely worth having for thousands of users of domestic operating systems and friends who are interested in Linux systems!

Speaking of which, many small partners may not be familiar with Android compatibility. Here are a few typical issues to give you an overview.

Application ecology has always been a key factor restricting the popularity of Linux desktop systems, and it is also an important problem that plagues Linux operating system manufacturers. Many application software familiar to users on Windows or Android platforms cannot find corresponding replacement software on Linux systems, or there is a big gap between the corresponding software functions and user experience and software on other platforms. When it is impossible to find replacement products, many operating system manufacturers can only invest in the development and maintenance of relevant software by themselves (such as the Sogou input method Linux version developed in cooperation with Sogou Company), but this development and maintenance will consume more manpower. At present, many industry software cannot be solved. The mature application ecosystem compatible with other platforms has always been an important direction to solve the shortage of operating system application ecosystems!

The application of the Windows platform has always been the target of everyone’s comparison and reference, so the early application ecosystem compatibility generally focused on the compatibility of Windows platform applications. The core solution is to migrate Windows applications by building a compatibility layer. For example, the typical WINE (Wine Is Not a Emulator) technology can solve the migration of some Windows applications (such as QQ, etc.) by building an API transformation compatibility layer. However, due to the closed source of the Windows system itself, the implementation and changes of some API interfaces will lead to abnormal application execution, and the compatibility and stability of application software are difficult to guarantee.

In recent years, with the maturity and development of Android software and hardware products, the Android application ecosystem has shown explosive development, surpassing Windows and iOS in many fields and becoming the most widely used application ecosystem. How to use and be compatible with the Android application ecosystem has become a new hotspot in the current industry.

There are currently two main approaches to mature solutions:

One is to use virtual machines and emulators such as Virturlbox, Qemu, Genymotion, and Avd to simulate Android hardware devices and operating environments, and realize the operation of Android applications. In particular, solutions for the running needs of Android games on the desktop system such as Hippocampus Play, Happy Android, Yeshen, and Tiantian emulator have developed rapidly in recent years. But these methods mainly have two problems: on the one hand, the performance overhead is large, and the use of virtual machines to run Android applications is usually many times slower than that of mobile phones. On the other hand, the user experience is insufficient. Because the file and other resource access of Android applications is isolated from the Linux system, it is not convenient to access and share resources.

Another solution is to use Google ARC technology Chrome browser to run Android applications. This method is much more efficient than virtual machines, but because it relies on Chrome browsers and related Google services, and because ARC is slightly less stable, there are not many compatible Android applications, resulting in limited application scenarios and scope.

The core of these two ideas is to build a virtual execution environment through the compatibility layer, and there will be a transition between the host and the virtual environment in the middle, which will inevitably face the loss of performance and ease of use.

Kydroid takes a different approach from the above solution. As you know, the underlying Android system is based on the Linux kernel, and the Kydroid operating system also takes the Linux technical route. This technical system similarity provides an important guarantee for the "native" operation of Android applications.

Kydroid builds a full set of native Android operating environments on the Kydroid operating system through kernel feature customization and migration of key components of the Android operating system (involving Bionic, Art, HAL, SystemServer, Init, etc.), so that the Android operating system and the Kydroid operating system are perfectly integrated, so that Android applications can be directly on top of the Kydroid operating system. This is not a virtual machine, nor is it an emulator, but a completely native operation.

Due to its native operation, Kydroid can provide better performance and experience, with key features including:

1. Low performance loss: Because it runs natively, Android applications are equivalent to running on a mobile phone with a computer hardware configuration, with no pressure on efficiency and dozens of times faster than virtual machines!

2.
