Well,he doubled for Mickey Hardt in scenes where swords are involved.So he didn't do that much(if you are referring to fact he is old).And don't forget Tino Wong always worked as extra.Wang Seung Lam does stuints since 1970's till these days.So why he can be but not Tino Wong?And the if this man isn't Wong,then who is he????
For comparison This is his picture when he was young,.
