Perhaps you should try some spelling variations:
wang oanh » wang yan, wang yang, wang ban
dang anh » duong anh
tran hua » tan hua, tran duc
tuan hua » tan hua, tuan vu, yuan hui
yang jie » yang jin, yang di, yang xi
yang jui » yang judy, yang di, yang xi
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) OR (dang anh)) ((tran hua) OR (tuan hua)) irene ((yang jie) OR (yang jui)) song sam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang oanh) OR (dang anh)) ((tran hua) or (tuan hua)) irene ((yang jie) or (yang jui)) song sam ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang oanh) OR (dang anh)) ((tran hua) or (tuan hua)) irene ((yang jie) or (yang jui)) song sam ;*.
