Perhaps you should try some spelling variations:
yan tran » oanh tran, anh tran, ca tran
yang jui » yang di, yang yi
yang jun » pang jun, yang jin, yang fan
wong sau » wong sam, wong siu, wong shiu
tran yu » tian yu, tran duc
yu chen » yu cheng, yi chen, yulu chen
yang xi » yang di, yang yi
wang » wing, wan, lang

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 yan tran yu chen ((((yang xi) OR (((yang jui) OR (yang judy))))) OR (yang jun)) wong sau ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan tran yu chen ((((yang xi) or (((yang jui) or (yang judy))))) or (yang jun)) wong sau ;*.
