How many martial arts styles does Donnie Yen know?

Answer 1

Donnie Yen knows several types of Martial Art styles. Depends on how you look at it. His base is in Wushu which encompasses several different styles in and of itself. Aside from that he is well trained in Judo, Brazilian Jujitsu, Muay Thai, Wing Chun, MMA, Kickboxing, and other styles to varying degrees. Watching him spar it looks like he is well trained in Jeet Kune Do or Jun Fan Gong Fu but his experience is vast enough that he may have simply been emphasizing the same movements in those styles without knowing much about them.
