He has been in as many Shaw Bros' movies as just about anyone, with the exceptions of Ku Feng, Lo Lieh, and Tien Feng. Got his eyes put out in The Chinese Boxer and he can be seen giving just about everybody, who's "anybody" trouble. If he's not trying to bash someone's head in, he's up to no good in some other way. He couldn't quite kill Ti Lung the way he wanted to in Vengeance, so he blinded him and made it easier for everyone to kill him. He (later) starred with him, in the underrated film, King Eagle - giving a very nice performance, for the relatively, small role in played.
He's given some pretty good performances and knows he craft well. In The Wandering Swordsman, he played a killer constantly taunting Lily Li, before David Chiang put an end to his ways and in Crazy Horse, Intelligent Monkey; he was one of a trio of killers who seriously got their butts kicked by a (supposedly) crippled Chu Te-Hu. Though he plays second-class villains hasn't really hurt his image, because he's always front-and-center when it calls for trying to kill someone. Chen Kuan-Tai had to kill him with a car, to stop him from relentlessly trying to kill him, in Warrior Of Steel.
He's had a few chances to play "Good Guy" roles, like in 7 Soldiers Of Kung Fu, and in the cult-favorite Bruce & Iron Finger with Bruce Li and Bruce Liang (the first collaboration of Bruce Lee imitators). He doesn't seem to be one of those stars who can run either hot or cold, though most of the movies that I've seen him in. have all been pretty good. And given the roles that he plays, there's hardly room for too many bad performances. He gave an interesting performance as a Homosexual killer (with partner - Li Hai-Sheng) in the film, Knockabout.
