What martial arts are used in the martial arts action in the movie fuse?

From the beginning of the film, Donnie Yen used Sanda and Wing Chun in the competition (because it can be seen from the camera that he has been playing around the center line of the other side) and wrestled with Louis Koo in the bar! The two plots in the film can sum up all the fighting styles. One is to fight with the third of the three brothers involved in drug trafficking in a restaurant (the fighting methods are Taekwondo and boxing, mainly boxing). Second, fighting with the boss in a dilapidated building (fighting methods are capture, boxing, Sanda, jujitsu), the film makes so many kinds of martial arts for visual impact to make the story more real and moving! Hope to adopt!
