Coming from a Wrestling (Judo) background you'd think he's much tougher than he really is. The first movie that I remember seeing him in Fatal Needles, Fatal Fists was easy to remember, because of him hitting Wang Tao in the eye, with a whole chicken. Here, he reminded me of Mike Tyson, with a potbelly and curly hair. His best performance probably, was in 4 Hands Of Death with Jimmy Lee, where his skills as an actor and a fighter were used to great effect. In most of his films, his bark was worst than his bite and his performances varied, depending on the role he was playing.
He was amusing in the underrated hit, Killer From Above, where he swung a mean tree limb. He's worked with just about everyone in the kung-fu genre at one time or another and can be exciting (Blood On The Sun) or downright boring when not given much to do (Tattoo Connection). I hated movies where he just toss people around like he did in Duel With the Devils (starring Tan Tao-Liang), lending to the fact that he's just a big fat guy with no skill, which, of course, wasn't true. I don't think his true potential as an actor was ever really tapped by directors during his film career.
