Le Maître chinois

Though teenage Wong Fei Hong (Jackie Chan) is the son of a martial arts teacher, he'd much rather clown around and get in and out of trouble on the streets of Hong Kong than learn kung fu. When one of his pranks causes injury to the son of a powerful man, his father calls in a sadistic uncle to teach Fei Hung some self-discipline. The uncle specializes in a bizarre form of kung fu known as the "Drunken Boxer," and after losing a fight with a local assassin who has been hired to kill his father, Fei Hung realizes that it may be worth learning.
