Most might remember him as the guy Billy Chong gave the lesson to in the forest in the classic, Super Power (1980). He's appeared in a number of good Kung-fu films, unfortunately, in very small roles, where he either wasn't a major co-star or where he got killed off early in the film I remember him having a small part in the Shaw Brothers film, Finger Of Doom (1972).
The only film I can remember him in as the star, was the obscure, The Angry Dragon (1974). It was an average film, with decent fighting, but no "Edge-of-your-seat" excitement. While it gave him a leading role, it seemed to be missing something in the way of choreography.
