A good time to correct one of my original and long-standing slightly-misleading entries.
I've changed Wu Fung (id=2154)'s primary name to Woo Fung (2) ... and in the process, moved Woo Fung (1)'s 1993 movie credit (for Small Potato) to Woo Fung (2).
Editors : PLEASE be careful when adding Woo Fung to add Woo Fung (2), unless you are absolutely sure it is the older actor. Woo Fung is one of HK's very busy actors, and probably has quite a few roles still to be documented here.
Suggestion : Would it be too confusing to switch the numbers ?
I generally follow the convention of numbering people of the same names with earliest movie credit gets #1, next gets #2 etc, but it may be useful/expeditious to reverse the order in this case.
