Perhaps you should try some spelling variations:
wang oanh » wang yan, wang yang, dang anh
oanh tran » anh tran, anh tuan, binh tran
hua irene » hua ren
tran hua » tan hua, tuan hua, tran duc
yang jie » yang jin, yang xi, yang yi
yang jui » yang judy, yang xi, yang yi
song sam » wong sam, kong sar, song pae

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wang oanh tran hua irene ((((yang jie) OR (yang di))) OR (yang jui)) song sam ;~.
• Adding a wildcard symbol may retrieve word variants: wang oanh tran hua irene ((((yang jie) or (yang di))) or (yang jui)) song sam ;*.
