Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
yang jui » yang judy, yang di, yang xi
liu yang » liu yan, du yang, liu feng
wong sam » wong lai, kong sar, von sam
wong sau » wong siu, wong shiu, wong lai
yang yi » yang di, yang xi
von sa » von sam, von sap, von sl
keming » deming

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 ((yang jui) OR (yang yi)) liu yang keming ((((wong sam) OR (wong sau))) OR (von sa)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ((yang jui) or (yang yi)) liu yang keming ((((wong sam) OR (wong sau))) or (von sa)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong ((yang jui) or (yang yi)) liu yang keming ((((wong sam) OR (wong sau))) or (von sa)) ;*.
