Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
sang minh » kang minah, anh minh, song min
wong shiu » cong shu, song shin
yang jun » yang jui, pang jun, yang jin
wong siu » kong siu, wong siew, dong sin
wong sau » wong sam, wong lai, kong sar
yang li » yang lin, yang di, yang xi
xu sang » du sang, xu gang

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 li) OR (yang jun)) xu sang minh ((wong siu) OR (((wong sau) OR (wong shiu)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ((yang li) or (yang jun)) xu sang minh ((wong siu) or (((wong sau) OR (wong shiu)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong ((yang li) or (yang jun)) xu sang minh ((wong siu) or (((wong sau) OR (wong shiu)))) ;*.
