Added a couple names:
Lee Goon-Cheung and Chiu Keung (1)

Is this Chuen Yuen? (http://www.hkmdb.com/db/people/view.mhtml?id=3804&display_set=eng)



Man Man (2)? (http://www.hkmdb.com/db/people/view.mhtml?id=14746&display_set=eng)

I think that is Chuen Yuen, yes Looks right for Man Man too.

I don't think your ID for Chiu Keung (1) is correct though - the portrait belongs to a rather minor character, not somebody I'd expect to have made it into the credits. I think Chiu Keung (1) is this guy:



But he looks too old...

Now that I look at it again I think you're right - that pic is not Chiu Keung (1).

I think you could be right in your chioce. He didn't have a very long career, so he could have started late?

Both pictures in your last message are Chiu Keung (1).

Added ID and role name for Chiu Keung (1). Any more?

Updated cast list and image gallery.

Go Fung (1) is Go Ming (2) using another name. I add the alias, the credit and the image in a few days to Go Ming (2) if no one objects.
