Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
sang minh » kang minah, anh minh, song min
yang lin » yang jin, wang lin, yang li
yang jie » yang jin, yang di, yang jui
wong siu » wong shiu, kong siu, wong siew
wong sau » wong sam, wong shiu, kong sar
xu sang » du sang, xu gang
lai » laid

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