Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
gan xiao » gan jiao, fan xibo, yap xiao
yuan kai » yuan kang, yuan fei, tan kai
kai chen » kang chen, jui chen, yi chen
yang jui » yang judy, yang yi
wong sam » wong sau, wong lai, kong sar
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: gan xiao yuan kai chen ((((yang yang) OR (((yang jui) OR (yang xi))))) OR (yang di)) wong sam ;~.
• Adding a wildcard symbol may retrieve word variants: gan xiao yuan kai chen ((((yang yang) or (((yang jui) or (yang xi))))) or (yang di)) wong sam ;*.
