Ko Pao

is the same person as
Got Hiu Chung
http://hkmdb.com/db/people/view.mhtml?i ... ay_set=eng

If nobody objects, I will merge those names in one week.

I also strongly suspect that Got Fook Chung is another alias, but someone who has seen those films would need to confirm if he is there.

I check this weekend "Ferocious to Ferocious" with Got Fook Chung in the cast list to see if Ko Pao appears. But I don't remember seeing him in the movie. At monday I can say more.

I checked "Ferocious to Ferocious". Ko Pao is not in the movie (I have the dubbed version).

Ko Pao and Got Hiu Chung merged.
