Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
yong yang » yang yang, dong yang, ying yang
yang liu » yang li, yang lin, yang di
liu gang » liu gangs, li gang, liu feng
liu yang » liu yan, du yang, liu feng
wong sau » wong siu, wong shiu, wong lai
wong sam » wong lai, kong sar, von sam

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