Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
sang minh » kang minah, anh minh, song min
wang lin » wang li, wang qin, yang lin
yang jun » yang jui, pang jun, yang jin
kong siu » kong eiu, dong sin, kong sar
wong siu » wong shiu, wong siew, dong sin
wong sau » wong sam, wong shiu, wong lai
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 ((wang lin) OR (yang jun)) xu sang minh ((((kong siu) OR (wong siu))) OR (wong sau)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ((wang lin) or (yang jun)) xu sang minh ((((kong siu) OR (wong siu))) or (wong sau)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong ((wang lin) or (yang jun)) xu sang minh ((((kong siu) OR (wong siu))) or (wong sau)) ;*.
