I really like Chan's Who am I it has some of the best fight scenes I think especially the fight on the roof. Also Black Dragon has some pretty good stuff (and I own that one so you can borrow it)...and as Fame said First Strike also has some pretty good stunt work in it.

If you want to go another way with Chinese cinema you cold go for some of the wire work films like my favorite The Bride with White Hair or Heroic Trio and actually Heroic Trio is directed by Johnny To - which I recommend you watch several of his films Running Out of Time I & II, The Mission, Fulltime Killer, and the pretty funny Running on Karma.
