What evidence suggests that these are 2 different people?

If the name was split along acting and directing/ass.directing I'd be less suspicious...

if nobody stops me in 15 days I will merge them.

In my opinion they are two persons.

Man Man (2) worked only in Taiwan and I never saw a movie shoot in HK with him. He is not in "Tea House" with Man Man (3) listed as actor (I checked that movie many times).

I agree with Michael; they are two different persons.

2 against 1, I will not touch them.

OK
