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

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) OR (tuan hua)) irene ((((yang jie) OR (yang xi))) OR (yang jui)) song sam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang oanh ((tran hua) OR (tuan hua)) irene ((((yang jie) or (yang xi))) or (yang jui)) song sam ;~".
• Adding a wildcard symbol may retrieve word variants: wang oanh ((tran hua) OR (tuan hua)) irene ((((yang jie) or (yang xi))) or (yang jui)) song sam ;*.
