Chen Kexin flew nonstop to Seoul, Thailand, China, Hongkong and the Mainland for intensive post-production. He worked for 40 hours without sleep, and slept just enough on the plane. During the filming of "Martial Arts", some netizens joked that Jincheng's "Zhen", "Zi Dan", "Tang Wei" and "Wu" were simply "really mighty". Hearing this, Donnie Yen joked that this is "really terrible" with Chen's "can" heart. Although he has left the film industry for more than ten years, as the first person in the "One-armed Knife" series, Wang Yu has many international fans like quentin tarantino and Yuan Heping in the international film industry. As soon as the news that "Martial Arts" was shortlisted for Cannes came out, the French publisher TF 1 "booked" the slot of Wang Yu to the film producers at the first time, hoping to reproduce the legend of "the king of one-armed knives" on the red carpet. "Not handsome, just strange" is Takeshi Kaneshiro's modeling concept in "Martial Arts". "Although Takeshi Kaneshiro has only one costume, it is a luxury from head to toe, and it is a genuine antique." In the film, there is only one antique straw hat worn by Takeshi Kaneshiro in the world, and the crew also specially equipped with a safe. During the filming, no matter where Takeshi Kaneshiro goes, the safe will be taken away. The first scene of Takeshi Kaneshiro's "Kung Fu" is "Autopsy". Although "corpses" are all made of special materials, they must be photographed within one day to ensure their "fresh" texture. As a result, Takeshi Kaneshiro's "Autopsy" plays accumulated more than 100, and became a veritable "Autopsy Emperor". Takeshi Kaneshiro admitted that he was troubled by the "corpse" and had nightmares. In order to make the "autopsy" professional, Takeshi Kaneshiro also studied every posture carefully from disembowelling to sampling under the guidance of a surgeon. In this movie, Takeshi Kaneshiro's lines are all Sichuan dialect. On the first day, he made up his mind. He made a lot of jokes because he was unprepared. Later, when I was working in the field, I learned it from a Sichuanese, so I chatted in a daze for two days. On the third day, I specially transferred a tour guide from Chengdu as a teacher, but I found that the pronunciation of field work was different from this tour guide before, and I was confused in an instant. Who do you listen to? In order to learn Sichuan dialect, Takeshi Kaneshiro repeatedly listened to what the "masters" said in MP3, but because the "masters" all had different accents, his Sichuan dialect version was also a "mixed version". About 20 minutes after the opening of the film, Tang Wei and Donnie Yen are discussing whether to use swim bladder or eat mercury for contraception in the bathroom, but the next scene is abruptly shifted and a passionate scene is deleted. The version of "Martial Arts" shown in China is eight or nine minutes longer than that shown in Cannes, adding the scene of Tang Wei fishing in the water. This scene is about Tang Wei and Donnie Yen meeting for the first time by a stream, and how Tang Wei likes him. In addition to the "fishing drama" and the emotional drama of Tang Wei and Donnie Yen, the domestic version also added some empty shots of China elements.
