Perhaps you should try some spelling variations:
truong thanh » luong thanh, truong tran, tran thanh
yuan chang » yuan cheng, huang chang, han chang
chang kyun » chang yun, chang hsun, chang jiyoun
wang yuan » wang yuhan, wang yan, fang yuan
kyun pin » kyung min, yun hin
yang lin » yang jin, wang lin, yang li
yang jui » yang judy, yang xi, 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 yuan chang kyun pin ((((yang lin) OR (yang jui))) OR (yang di)) truong thanh ;~.
• Adding a wildcard symbol may retrieve word variants: wang yuan chang kyun pin ((((yang lin) or (yang jui))) or (yang di)) truong thanh ;*.
