　　Reference message networkReported on September 14th.According to the bimonthly website of Foreign Policy of the United States reported on September 6, more than 20 commanders and ordinary members of at least 12 anti-government armed groups in southern Syria said that Israel has secretly armed and funded these organizations in recent years to prevent the extremist organization "Islamic State" militants from occupying positions near the Israeli border.

　　According to reports, the military equipment transferred by Israel in July this year included assault rifles, machine guns, mortar launchers and transport vehicles. The Israeli security services transported these weapons through three passes connecting the Israeli-occupied Golan Heights with Syria. Israel also uses these checkpoints to deliver humanitarian aid to the residents of southern Syria who have suffered from years of civil war.

　　The picture shows the Israeli armored forces deployed in the Golan Heights.

　　Syrian rebels and local media said that Israel also paid salaries to rebels (about $75 per person per month) and provided additional funds. The rebels used the money to buy weapons on the Syrian black market.

　　These payments and the services received by Israel in return have caused the militants to expect that if the troops loyal to the Syrian government try to advance into southern Syria, Israel will intervene.

　　This summer, when the Syrian government forces supported by Russian air power did so, Israel did not intervene, making the rebels feel betrayed.

　　Y, a member of the Knights of the Golan, said: "This is a lesson we will never forget about Israel. It doesn’t care about … … These people. It doesn’t care about humans. It only cares about its own interests. "

　　According to reports, Israel tried to keep its relations with these organizations secret.

　　According to the report, compared with the amount of weapons and funds provided by Qatar, Saudi Arabia, Turkey and the United States and other countries involved in this seven-year civil war, the amount provided by Israel is small. Even when Israel’s aid program peaked earlier this year, rebel commanders complained that the aid was not enough.

　　However, Israel’s assistance is important for several reasons. This marks another way for Israel to try to prevent Iran from consolidating its position in Syria. Israel also launched air strikes against Iranian military bases in Syria and exerted political pressure through Russia.

　　Israel’s aid also raises questions about the balance of power in Syria when the civil war finally subsided. There is a great possibility that Syria will become a flashpoint of conflict between Israel and Iran when the Iranian army, which helped the Syrian government defeat the rebels, has no intention of withdrawing its troops from Syria.

　　According to the report, a spokesman for the Israeli Embassy in Washington declined to comment on this article.

　　The picture shows an Israeli tank on standby in the Syrian-Israeli border area.

　　According to reports, since 2013, Israel has provided weapons to anti-government armed groups allied with the Syrian Free Army, including some armed factions operating in Quneitra, Deraa and rural areas in southern Damascus. The weapons transferred at that time were mainly M16 assault rifles made in the United States. Later, most of the weapons provided by Israel to the militants were not American weapons (apparently to cover up the sources of aid), including some guns and ammunition confiscated by Israel in 2009 and transported from Iran to Hezbollah in Lebanon.

　　Aid to these organizations remained stable for some time, but it increased significantly last year. Israel has gone from supporting hundreds of fighters to helping anti-government organizations with thousands of members. The increase in aid coincides with a broader change in Israel’s policy toward Syria. After appealing to the United States and Russia, but failing to reach an agreement to allow Iranian-backed militia groups to leave southern Syria, Israel adopted a more aggressive policy. Its air force began to strike deeper into Syria, not only against individual batches of weapons shipped from Iran to Hezbollah, but also against bases all over Iran.

　　According to the report, two Israeli-backed organizations have been publicly confirmed, including the "Knights of the Golan" organization based in Tahaisheb, the border town of Quneitra, and the "Omar bin khattab" brigade based in Beit Kin, a town near Mount Hermon.

　　Unlike other foreign forces that support the Syrian opposition, Israel has made little effort to organize and consolidate its aid program. On the contrary, it obviously relies on the relationship established with individual commanders and provides them with assistance directly.

　　The picture shows the wreckage of an Iranian drone shot down by the Israeli army.

　　Anti-government militants in southern Syria say these commanders will contact Israeli officials by telephone and occasionally meet them in the Israeli-occupied Golan Heights. When these commanders change organizations and locations, Israel’s aid will change accordingly. On the other hand, when these commanders are killed or ousted because of internal power struggles, Israel will stop providing assistance to their former factions.

　　Knights of the Golan is a favorite organization of Israel. Members of the faction said that the organization added hundreds of fighters last year because of increased Israeli funding. It also distributes weapons provided by Israel to other organizations. This makes the organization have great influence in Quneitra and nearby Dar ‘a province.

　　Israel has also provided fire support to armed groups fighting against local branches of the Islamic State in the Yarmouk Basin. Local armed groups, media reporters and residents said that when the "Islamic State" organization was fighting other anti-government armed forces, the Israeli army launched a drone attack on the commander of the organization and launched a precision missile strike on the personnel, fortifications and vehicles of the organization. When the rebels launched an attack on the Syrian government forces, Israel did not provide similar fire support.

　　The report commented that due to Israel’s humanitarian and military assistance, many residents in southern Syria gradually regarded it as an ally. Israel promotes its "good neighbor" plan in Arabic, including humanitarian operations in southern Syria and the treatment of some Syrian people in Israeli hospitals.

　　A few months ago, Y, a militant of the "Knights of the Golan" organization, said: "Israel is the only country that has interests, a little humanity and provides assistance to civilians in the region."

　　However, as that Syrian government force regained control of more and more Syrian territory with the help of Russian and Iranian army, Israel began to seek other ways to safeguard its interests in the border area.

　　In July this year, Israeli officials apparently reached an understanding with Russia to allow government troops to return to the western part of Dar ‘a province and Quneitra, which are adjacent to the Golan Heights. According to reports, in exchange, Russia promised not to allow Iranian-backed militia groups to enter within 80 kilometers of the Golan Heights, and would not begin to obstruct Israel from attacking Iranian targets in various parts of Syria.

　　Even after the Syrian government forces began to launch an offensive against southern Syria, many Syrians in the region still held the hope that Israel would at least prevent the Syrian government from retaking the neighboring province of Quneitra. Thousands of people fled to the area adjacent to the Golan Heights, but Israel did not intervene to protect them.

　　A local community leader in the western part of Dar ‘a province said that he soon realized that it was a mistake to rely on Israel.

　　"Believe me, Israel will regret its silence about what happened in southern Syria," he said. People in our town and some neighboring towns have barely reached a reconciliation with the regime, but this reconciliation will affect Israel in the near future. "

　　According to the report, when the Syrian government forces approached, some anti-government militants contacted their Israeli acquaintances and sought asylum for fear that the government forces would retaliate. Israeli officials responded by allowing a few anti-government commanders and their immediate families to enter Israel on the night of July 22. Others were turned away.

　　The whereabouts of these commanders and their relatives are still unknown. Syrians say that some people are said to be in Israel and others are in Jordan. A former commander informed his subordinates that he had arrived in Turkey.

　　As for ordinary combatants, most people choose to stay at home and surrender to the government instead of fleeing to Idlib, the only remaining enclave of anti-government forces. Some have been arrested, apparently for cooperating with Israel, while others have joined pro-government militias or Syrian government forces. (Compile/Yan Fang)

　　[car home Engine Disassembly] It’s human nature to like new things, and you won’t miss an important new car like brand-new (|). But I’m sorry, the new car hasn’t come on the market yet, and even the test drive report hasn’t been seen yet, but it doesn’t matter. Let’s take a look at the new 1.5T GDI engine on the new GS5 first.

● Basic information of engine

　　We noticed that the cylinder diameter/stroke ratio of GAC, a brand-new 1.5T GDI engine, has become smaller. This change of long stroke is helpful to improve the engine torque and make the engine respond better at low speed.

　　However, by comparing the power parameters of the three engines in the above table, we can intuitively see that the same 1.5T engine has different tuning and the maximum power/torque is different. Take the maximum horsepower as follows: Honda 177Ps＞ > Chuanqi 171Ps＞ > Great Wall 169Ps, but the maximum torque is reversed: Great Wall 285N·m＞ > Chuanqi 265ps. Chuanqi’s self-positioning in this "challenge" is quite clear. The setting of power parameters is not blindly adjusted upwards, but on the premise of ensuring power and torque, the output speed of maximum power is lowered and the output speed range of peak torque is widened.

　　Of course, Chuanqi 1.5T GDI engine, as one of the "three big parts" of the whole vehicle, is an important factor that many consumers consider before buying a car. This disassembly is more to help consumers clarify the advantages and disadvantages of Chuguangqi 1.5T GDI engine. AB: What is the difference (highlight) between Chuanqi GS5 1.5TG DI and GS4 1.5T engine in 2019? What gains can these highlights bring?

● What are the highlights of GAC’s 1.5T GDI compared with the previous 1.5T?

Highlight 1: change from manifold injection to in-cylinder direct injection

　　First of all, the biggest difference between this 1.5T GDI and GS4 1.5T engine lies in its name-GDI (in-cylinder direct injection). The most direct benefit of changing the fuel injection system from manifold injection to in-cylinder direct injection is that the engine power performance is improved and the harmful gases in the exhaust gas are relatively reduced. Moreover, we know that the first-tier cities in China will soon implement the more stringent national six emission standards. As a car company, GAC must be ahead of the policy, so this engine adopts in-cylinder direct injection technology to achieve the national six emission standards.

　　It is worth mentioning that "National VI" refers to a national policy standard for automobile exhaust emission. After the implementation of the "National VI" emission standard, it will be divided into two stages: "National VI A" and "National VI B", which will be implemented on July 1, 2020 and July 1, 2023 respectively. In some emission standards, "National VI B" is more than twice as strict as "National VI A" )

　　It is worth mentioning that with the help of turbocharger, a higher compression ratio means that the engine is more efficient, can improve more power performance, and saves more fuel, etc. After all, the working feature of direct injection engine is to directly inject fuel into the cylinder, and use the air flow in the cylinder and the fuel on the piston surface to achieve better atomization effect.

　　Direct injection engine has a good performance in working uniformity and performance under full load, and even the problem of working instability of cold car has been significantly improved. Of course, things are two-sided. While the engine enjoys the power improvement brought by high compression ratio, it is also a test for the fixation of high-pressure fuel rail and the fuel pump pressure of the fuel supply system.

　　The "dadada" sound of direct injection engine during fuel injection has always been a headache for engine NVH engineers. We can see their solutions on GAC 1.5T GDI this time:

　　When the engine is running in the compression stroke, the pressure in the cylinder is very large. For in-cylinder direct injection engines, ordinary fuel pumps can’t meet the demand. Another important feature of in-cylinder direct injection engine is that the fuel supply pressure of fuel pump is very high, so that gasoline can be effectively injected into the high-pressure combustion chamber.

　　Because of the combustion characteristics of gasoline, the compression ratio of ordinary engines can’t be designed too high, otherwise it is easy to knock, so most direct injection engines will divide the fuel injection process into two stages, that is, two injections. The GAC 1.5T GDI engine made a small breakthrough in fuel injection-The strategy of "three injections per cycle" is adopted under the specific working condition of "high load and low speed"(It can be understood that the fuel is injected three times per cycle only when the vehicle starts, and it is injected twice in other working conditions): The first-stage pre-injection (which occurs in the intake stroke and the crank angle is about 360°~180°CA) can take away a lot of heat in the cylinder under the action of gasoline volatilization, and reduce the cylinder temperature, so as to achieve a lower ignition angle, and to effectively suppress the probability of knocking and ensure stable combustion. The second and third main fuel injection (which occurs at the end of compression stroke and before power stroke, and the crank angle is about 0°CA) can bring higher exhaust temperature and accelerate the light-off of three-way catalyst.The advantage isTo achieve a rapid start, reduce engine emissions, meet the national six B emission standards, and reduce fuel consumption.

Highlight 2: Switch to exhaust gas turbocharger with lower inertia.

　　Although turbocharging technology is not a brand-new technology, it is the mainstream development direction to apply turbocharging technology to small displacement engines. Thanks to the ingenious design of turbine blades, the low inertia exhaust gas turbocharger provided by Borgwarner can take into account both high speed and high power and low speed and high torque.

Highlight 3: The three-way catalytic converter has added more precious metals.

　　Engineers have made a lot of efforts to purify the exhaust gas in order to make the exhaust gas from the 1.5T GDI engine meet the national sixth B emission regulations. The biggest highlight is the adoption of a brand-new three-way catalytic converter and the addition of more precious metals in the catalytic converter, thus reducing the light-off temperature to 270℃. What is the concept of 270℃? Let me give you an example for your reference: the light-off temperature of the three-way catalytic converter in the general national standard is 400℃, and the difference between them is 130℃.

　　The author jokingly said here: the exhaust gas discharged by an engine that can meet the national six B emission regulations should be cleaner than the air in many cities, right? Is that engine like a walking "air purifier"?

Deep Blue Auto will officially release S7 on May 20th, and start the pre-sale. Deep Blue S7 is the first SUV of Chang ‘an EPA1 platform, and the second production car of Deep Blue Automobile. The new car is positioned as a medium-sized SUV, which will provide three power systems: pure electric, extended range and hydrogen electric. The exterior interior adopts the family design concept, which is highly similar to SL03, so that many people question whether S7 is a simple SL03 face-lifting operation. Let’s combine the details of Deep Blue S7 to answer this question.

At first glance, the dark blue S7 looks like the heightened version of SL03. The front and rear light groups are indeed copied directly, but the details are still different, such as the more exaggerated bright black vents, the bright black body surrounding, and the brand-new sports wheels, which are all unique places of S7. The vehicle size is 4750/1930/1625mm and the wheelbase is 2900mm.

(You can see the frameless door and the new aluminum alloy sports wheel hub in the picture below.)

The black decorative pieces on both sides of the front of the car have 696 LED light beads, which can realize custom interactive lighting. The rear bumper comes standard, including extended version, and there is no exposed exhaust pipe.

The interior layout of the dark blue S7 is quite different from that of the SL03. On the one hand, the embracing front row is adopted, and there is an obvious arc transition on the outside of the driver and the co-pilot. On the other hand, the independent instrument panel is cancelled, and the instrument panel is replaced by the AR-HUD head-up digital display. On the one hand, the 15.6-inch touch screen supports 15-degree adjustment from left to right, which can take care of the independent use needs of the driver and co-pilot.

The dual-pair steering wheel is equipped with multi-function buttons, which can realize the functions of adaptive cruising at full speed, answering telephone calls, etc. The gear shift lever is adopted, and the gear shift lever also integrates the cruise control button, which needs to be used in conjunction with the button on the left side of the steering wheel. This design feels a bit redundant.

The car system adopts Qualcomm Snapdragon 8155 chip, which will support basic functions such as car networking, OTA upgrade, WIFI hotspot, gesture control, facial recognition, GPS navigation and voice recognition control. In this respect, you can refer to SL03, and it will also provide NID3.0 pilot intelligent driving assistance system and energy recovery system.

Deep blue S7 has a wheelbase of 2900mm, which is in line with SL03. It will be equipped with zero-gravity seats, and both the main driver and the co-pilot support electric adjustment, heating, ventilation, massage, and leg rest extension, thus further improving the comfort experience. In terms of space, the height of 1.8 meters is adjusted to the lowest sitting position in the front row, with one punch and two fingers left in the head, two punches in the back leg space and one punch left in the head.

The rear row is equipped with automatic air conditioning, and the control panel also supports adjusting the distance between the sunroof sunshade and the front and rear of the co-pilot seat, with an air outlet. The middle platform in the rear row is flat, and the comfort of the middle passengers’ feet is guaranteed. The new car is expected to use SONY Sony stereo, but the audio label is changed to "DEEPAL", which is a deep blue brand website, not an audio brand.

The deep blue S7 trunk has a width of 1000mm, a height of 710mm, and a depth of 1950mm after the rear row is laid down.

　　　　[XCAR Technology Original]

　　　　Since the day when the automobile was invented, a "bad guy" who followed the vehicle along with it also appeared at the same time, and that was noise. In order to give users the best driving experience, in the past decades or even hundreds of years, car manufacturers have been fighting the "bad guy" of noise endlessly.

　　　　Now, automobile manufacturers will adjust their vehicles through strict noise control standards to ensure that each vehicle can achieve a good level of noise and vibration suppression when leaving the factory. Recently, the author was lucky enough to participate in and experience the NVH test of Changan Auchan. In the test, I experienced Changan Automobile’s emphasis on the development of Auchan’s NVH. So what "magic weapons" did Changan Automobile use to control Auchan’s NVH? Let’s continue to look down.

1. What is NVH?

　　　　NVH is the abbreviation of Noise, Vibration and Harshness. Noise and vibration are easy to understand. To put it bluntly, the roughness of acoustic vibration is those uncomfortable feelings, such as harsh, roaring sound and uneven vibration. NVH is the core index to measure the comfort and quality of a car, and the feeling it brings to users is also the most direct.

　　　　According to statistics, four of the top 10 complaints of consumers about automobiles are about NVH, namely, engine noise, tire noise, wind noise and body noise. About one-third of the complaints of the whole vehicle are related to the NVH problem of vehicles, and nearly 20% of the research and development expenses of major car companies are spent on solving the NVH problem of vehicles.

　　　　It can be seen that NVH is very important for both the vehicle itself and the brand, because it can give consumers the most intuitive impression and directly affect consumers’ perception of the "texture" of the vehicle, so it is an important task for all car companies to develop NVH well. At present, NVH is mainly determined by these points: government regulations, customer requirements, company needs and technical capabilities, competing models.

　　　　At present, automobile sound control has gone through three development stages:

　　　　1. Reduce noise: solve the error state of NVH and reduce noise.

　　　　2. Sound quality control: make the sound comfortable, meet the requirements of specific customer groups, and the sound of the vehicle model is personalized.

　　　　3, sound quality DNA: the model is personalized and the brand voice is differentiated.

　　　　Through the above three stages, the transition from noise control to sound design has been realized.

Second, the control of Auchan NVH

　　　　The vehicle noise that we can hear is usually generated by the noise source and transmitted through the channel to reach our ears. Generally, noise sources and transmission channels are controlled to reduce noise. Simply put, this is the transmission of sound in physics, and noise reduction should be suppressed from the source and propagation.

　　　　Generally speaking, vehicle noise is mainly divided intoAir soundandStructural sound：

　　　　Air sound sources: engine radiation noise, air inlet noise, air outlet noise, tire radiation noise, etc.

　　　　Structural sound sources: engine vibration, exhaust hook vibration, chassis vibration, transmission bearing vibration and so on.

　　　　Two kinds of sound sources are transmitted through the car body, and the air sound source reaches our ears through the car body barrier and car body sound absorption; The structural sound source reaches our ears through the body structure, bracket and vibration isolator. These two kinds of sound sources are transmitted and attenuated to form the interior noise together.

　　　　After understanding the generation of noise, let’s see what anti-noise and vibration capabilities Auchan has. Auchan, as an MPV model with high hopes from Chang ‘an, naturally invested a lot in NVH. We found many NVH development achievements on Auchan’s car body.

　　　　In the overall design, Auchan has optimized the acoustic vibration transmission structure such as modeling, powertrain, car body and chassis suspension, so as to reduce the noise source and isolate the transmission of vibration and noise outside the car.

　　　　The first is engine noise suppression. Auchan’s 1.5L naturally aspirated engine has done a number of treatments in silence, including valves, fuel injectors, air intake systems, silent pulleys, etc., which reduced the engine noise at the source. According to official data, the idle noise value of Auchan is only 39 decibels.

　　　　Auchan soundproofed the engine to reduce the noise from being transmitted into the cab through the front wall, fender, hood and other channels. The composite sound insulation and absorption material is pasted under the hood, which can absorb and reduce the noise of the engine and suppress the vibration of the hood.

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. Nowadays, the first thing for consumers to buy a car is to see whether this car is rich in configuration, and it is no exception to nature. As for the outstanding performance of the car, please read it together.

Let’s take a look at the appearance of Exploration 06. The front face of Exploration 06 has taken a young and fashionable route, which is very recognizable. Headlights are very in line with consumers’ aesthetics and outline a deep effect. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light, delayed closing and so on. Coming to the side of the car body, the size of the car body is 4500 mm * 1865 mm * 1680 mm. The car adopts fashionable and dynamic lines, and the car body looks very spirited. With large-sized thick-walled tires, smooth lines run through the whole car side. In the rear part, explore the overall shape of the 06 rear and the front of the car, and the taillights present a fashionable and sporty design style, which is neat and vivid.

When I came into the car, the interior looked very sedate and reflected the sense of design. The steering wheel of the car is very domineering, made of imitation leather, and its practicality and face value are not bad. Take a look at the central control panel, which is decorated with a 13.2-inch central control panel, making the interior design quite layered and elegant. The interior feels good. Let’s take a look at the dashboard and the seats. The dashboard design is remarkable and looks very individual. The car uses leather seats, which are wide and thick, and the overall comfort and wrapping are not bad.

Explore 06 matching wet dual clutch (DCT) gearbox, with a maximum power of 145KW and a maximum torque of 290N.m, with good power performance.

Do China audiences still want to enjoy the movie plot of a five-foot-four-inch-tall Qing Dynasty man in a gown and pigtails who defeated the Western Hercules with his bare hands?

Twenty years ago, the answer was yes. In the series of movies of Huang Feihong, Ren Shiguan plays a down-and-out martial artist who is dressed in hard qigong, but still laments that "he can’t compete with foreign guns". In a blink of an eye, Huang Feihong, who traveled to the United States, has evolved to avoid revolvers by flying. In such a script market that pursues strange feelings, it is natural and reasonable for an oriental culture learner who seems to have no advantage at all to rely on Zen machine to defeat white muscular men. If he can give a sermon, it will be more convincing.

But now it’s 2015, and most viewers have stopped eating this set. People know Gracie, Bo Qiu and Fido &bull; Emilianko knows what fighting is all about. Movies such as ong bak, Warrior and Winter Yin Gong, with the theme of fighting, are popular all over the world. It is hard for producers to try to replicate the imaginative imagination of action movies in the 1990s in China, but it is hard not to gain ridicule.

Actor Jason Wu may be the best narrator of this performance revolution. He recently participated in two fighting movies &mdash; &mdash; Wolf Warriors and Breaking Wolf 2, especially the latter, quickly became the dark horses at the box office last week. The audience was pleasantly surprised by the change of Jason Wu’s performance style, and even felt that even his baby face for many years began to show vicissitudes.

In the early TV dramas such as Tai Chi Master and Kung Fu Kid, Jason Wu’s role always continues the traditional pattern of "Kung Fu Kid". It is difficult for the audience to distinguish the protagonists in these stories. Whether he is Fang Shiyu, Hong Xiguan or Yang Luchan, they are all laughing and laughing, with deep internal forces and can fly over the eaves. The characters in these films and TV plays are similar.

In 2005, Jason Wu was invited to play a killer who is good at using a knife in the action movie kill the wolf starring Donnie Yen. This model role was inherited by Zhang Chi in Kill the Wolf 2.

Donnie Yen was unlucky before, and his film achievements were always inferior to those of his peers, Jet Li. However, Donnie Yen is willing to practice new ideas of action movies. He himself has been exposed to free fighting, and kill the wolf has become a testing ground. In the film, Donnie Yen fights with Jason Wu in an alley with a crowbar &mdash; &mdash; I didn’t design the action in advance, but I relied on my free play. Jason Wu later claimed that he didn’t know that he would really fight, but it obviously gave him a lot of inspiration.

Kill the wolf’s biggest breakthrough lies in the duel between Donnie Yen and Sammo Hung, the ultimate villain. They abandoned the usual performance routines of China action movies and conducted an all-round comprehensive fighting. When Sammo Hung was young, he also had a duel with Bruce Lee, an early advocate of the concept of mixed fighting.

In modern MMA, fighting skills, wrestling skills and sleeping skills are all regarded as indispensable, and close combat in various positions can be taken from different schools. For example, you can throw your opponent, you can also use the knee strike in Muay Thai, you can also use the cross in Brazilian Jiu Jitsu, and even give your opponent a trick to split the door &mdash; &mdash; As long as you don’t show any flaws. Donnie Yen used them one by one in his own film experiments.

After kill the wolf, Jason Wu’s acting style changed obviously. In 2006, he filmed Black Boxing with a strong mixed fighting atmosphere, and then, Jason Wu led the action film Spike in 2008. Jason Wu performed hard, trying to express the theme of "fighting hard", but the whole film was still full of Weiya performances and exaggerated fights. At the end of the film, Jason Wu frightened many viewers with the heroic plot of one enemy against a hundred. Spike’s box office reputation is bleak.

In 2007, Jason Wu played the villain No.1 in The True Color of Men. This film is very realistic in the fighting scene, but it still has to bow its head in front of the action film Fuse, which was created and starred by Donnie Yen in the same year. "Fuse" is regarded as the pinnacle of Donnie Yen’s action movies, in which more than 7 minutes of mixed fighting is repeatedly interpreted on the Internet as a textbook-style video material &mdash; &mdash; This is due to the on-site guidance of a large number of MMA masters. Jason Wu missed the film. Donnie Yen, 44, announced that the fuse would be the end of his action movie.

Donnie Yen is not the first actor to try a new martial arts performance. In Thailand, Tony &bull, who studied orthodox Muay Thai; Jia’s momentum is in full swing. His films "ong bak" and "Winter Yin Gong" have been successful at home and abroad, and he also tried to break into Hollywood. From the audience’s point of view, Tony Jia practices one of the most powerful boxing skills today, with solid kung fu and a good sense of the camera. More importantly, he is still young.

In the American market with high-quality mixed fighting competitions, people are not keen on dazzling fighting actions. But there is still Gavin &bull; Director O ‘Connor’s Fight tells the story of MMA athletes. The China version of this film was born in 2013. Guild Wars directed by Lin Chaoxian used male stars such as Nick Cheung, Eddie Peng Yuyan and Andy On. Except Nick Cheung, all of them were new generation idol actors. Suddenly, everyone received MMA training and played quite well. This film became a dark horse of that year, and both the theme and the effect were surprising.

The upsurge of mixed martial arts even spread to the animation field. In the third part of the widely sought-after domestic animation "Qin Shi Ming Yue", there were a lot of MMA actions in the character confrontation, and the chivalrous men in the late Qin Dynasty showed their surrender skills to each other like Brazilian jujitsu masters.

Compared with China’s action actors’ extensive preference for mixed fighting performance, Tony &bull; Jia’s Muay Thai is inevitably monotonous. After several films and years of exposure, Tony &bull; Jia vaguely noticed the arrival of his own bottleneck period. In 2012, Indonesian director gareth &bull; Evans’s "Raid" was born, and continuous shooting made two films, each of which was amazing. The massive hand-to-hand combat in "Raid" made the film highly appreciated. It also made many people turn their attention to Indonesia, which was originally not amazing.

In Asia, almost all countries have martial arts traditions worth showing off. Although they are rarely shown in movies, the wand in the Philippines, Bankasula in Indonesia and even Majia in Israel are all unique. Action filmmakers from all countries will not ignore their own cultural treasures.

Under great pressure, Tony &bull; Jia and Jason Wu were brought together. Before that, Jason Wu completely embarked on the road of tough guy. He experienced life in the army and was injured or collapsed in various studios. He has appeared in two military movies, I am Special Forces 2 and Wolf Warriors. After polishing, Jason Wu is no longer the dashing constantly chauffeured figure in "Jiangshan comes first".

At this time, it has been ten years since the release of kill the wolf. This sequel "Kill the Wolf 2" is by no means a perfect work. In my opinion, it still has many disharmonies and even serious injuries. Even the reference relationship between the word "kill the wolf" and the characters in the film is obviously not as reasonable as the first one. In the arrangement of martial arts guidance, Tony &bull; Jia’s iron elbow and steel knee are also not able to coordinate with Max Zhang, who is dressed in a suit and moves like an ace agent. But in terms of performance, this film is embracing the future.

For a long time, action movie lovers have regarded Tony &bull; Jia is regarded as Donnie Yen’s imaginary enemy. Whether the title of "The Fuse" intentionally or unintentionally coincides with "The Pirate of the Buddha Line" (alias of "ong bak") or Donnie Yen’s "Tony, you are finished" at the end of the film, it is so subtle. People thought it would eventually be Donnie Yen and Tony &bull; Jia co-produced a male film full of blood. But now, it is Jason Wu who holds the baton.

This time, Jason Wu, with bare tendon and sparse stubble, focused on naked wringing, hook, axe elbow and knee strike in the play, instead of hand folding fan and knocking down the strong enemy in an anti-mechanical way. No one doubts his baby face any more. Forget those kung fu boys, and let the martial arts belong to the martial arts and the mechanics to the mechanics.

Does that mean that the future of action movies belongs to professional fighters? Maybe we should go to K-1 or UFC champion to find the next Tony &bull; Jia? Not necessarily. Generally speaking, fighters who come out of the arena always face limitations in performance. Zhou Bili and Lu Huiguang both played supporting roles or villains for many years in their acting careers, and Hai Long Liu, a famous Sanda player, did not perform well in Tough Guy 2. We can imagine that even if a producer invited Bo Qiu, the most respected in Muay Thai, to star in the sequel to ong bak, I’m afraid the effect will not be better than Tony &bull, who has a pleasant face; Jia.
