I notice both names share the same chinese characters.
Chan chin pang has only 1 credit - "evil fade" and
searching the web show he has others -

such as "ghost office, distinctive, diamond hill, shanghai affair, rape trap, tough guy, they don't care about us".

I believe both are the same person.

You are right, Mr. WilliamWan.

Chan Chin Pang of "Evil Fade" has the same symbols than Woody Chan. And Woody is credited in almost all the films you found.

If nobody objects in 15 days, I will merge these two people.
