Perhaps you should try some spelling variations:
wan hyoung » wang hyoung, man houng, min hyoung
hyoung gun » young eun
wong laid » wong lai, kong land
ying jin » yang jin, jing ji, yang jie
yang jui » yang judy, yang di, yang xi
wong sam » wong sau, wong lai, kong sar
yu chen » yu cheng, yi chen, yulu chen
won sau » wong sau, wong siu
gun yu » lun yu, yun yu

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: wan hyoung gun yu chen ((ying jin) OR (yang jui)) ((won sau) OR (((wong sam) OR (wong laid)))) ;~.
• Adding a wildcard symbol may retrieve word variants: wan hyoung gun yu chen ((ying jin) or (yang jui)) ((won sau) or (((wong sam) or (wong laid)))) ;*.
