Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang shiyong
chan ming » kian ming, chan eng, chan fong
liu chan » lily chan, liu yan, liu jan
wong siu » wong shiu, kong siu, wong sau
yang xi » yang di, yang yi, yang jui
xi liu » x liu, xu liu
von sa » von sam, von sap, von sl

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 yong) OR (wang yan)) yang xi liu chan ming ((wong siu) OR (von sa)) ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang yong) or (wang yan)) yang xi liu chan ming ((wong siu) or (von sa)) ;*.
