Pretty sure this is Sunny Fang Kang, but if I'm right then his role name isn't



Lam Chi-Tai?

You are right with Sunny Fang and Lam Chi-Tai (1).

Also ID of Cheung Wing-Cheung (2)

That Wu Chi-Lung ID is not correct:

The actor/stuntman at the image has good supporting roles in "To Catch a Thief"(91) (robber gang, name must be in the cast list) and "The Sting" (fake granny). He is also in a few Shaw movies (see "Weird Man") and "Double Impact". He is for sure not Wu (he is not in "Fist Power").
The real Wu could be the actor fighting brief with Kara Hui at the fight family against killers near the end of "Fist Power" because that actor is also in "City Hero".

What are the evidence for the ID? If there are no evidence and nobody has objections I delete the ID in a few days.

Removed wrong ID.
