I saw Siu Wa (3) acted in "The Rescue" & "Time for Love".

I believe these three are the same person. The only difference is one surname is in long hand & the other in short hand.

Can anyone confirm & update?

I think you are right that Siu Wa and Siu Wa (3) is the same person. I vote for merging the names.

I would vote for merging as well

Merged Siu Wa (only hkmdb credit: THE RESCUE) with Siu Wa (3):
