He is the brother of another kung-fu star Chin Hsiao-Hao, who fought against Jet Li in Tai-Chi Master and Fist Of Legends. He, himself, is probably most remembered in the excellent classic Operation Scorpio, with Liu Chia-Liang. Though, he's not in the same league as his brother, he is just as entertaining. He was very good in his portrayal of Wong Fei Hung, and though he has some decent fighting skills, he just couldn't elevate himself, above the masses of others, who tried to become superstars of the genre.
You can find him in Hong Kong action films like Bury Me High and others as he is still making movies. He won an award (and Praise) for his portrayal of the legendary Bruce Lee in the film The Green Hornet. He has also worked with Jackie Chan's stunt group (Hong Kong division) after appearing with him in the racing film Thunderbolt. Though, I personally, am still waiting on the sequel to Operation Scorpio, if they ever make one. Here's to wishful thinking.
