Fearless Hyena 2 (1983)

Five friends are released from prison and do their best to stay out trouble. While trying to mind their own business (and run their 5-Star Cleaning Service), they are caught up in a war between rival Triad gangs fighting for control of the counterfeit currency market.

Everyone abuses and humiliates a downtrodden orphan until he befriends an old man, who turns out to be the last master of the snake fist fighting style. Jackie becomes the old man's student and finds himself in battle with the master of the eagle's claw style, who has vowed to destroy the snake fist clan.
