Perhaps you should try some spelling variations:
truong thanh » luong thanh, truong tran, tran thanh
chang hsun » chang ch'un, chung hsuan, chang su
hui chang » huey chang, han chang, hui yang
hsun pais » un pais
wang hui » wang hua, wang zhi, wang wei
ying jin » yang jin, jing ji, yang jie
yang xi » yang yi, yang jui

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 hui chang hsun pais ((((ying jin) OR (yang xi))) OR (yang di)) truong thanh ;~.
• Adding a wildcard symbol may retrieve word variants: wang hui chang hsun pais ((((ying jin) or (yang xi))) or (yang di)) truong thanh ;*.
