Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
song ming » song bing, song min, gong min
yang lin » yang jin, wang lin, yang liang
yang jun » yang jui, pang jun, yang jin
kim song » kim young, kim eung
wong sau » wong sam, wong shiu, wong lai
wong siu » wong shiu, kong siu, wong siew
yang li » yang di, yang xi, yang yi

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 li))) OR (yang jun)) kim song ming ((wong sau) OR (wong siu)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yong ((((yang lin) or (yang li))) or (yang jun)) kim song ming ((wong sau) or (wong siu)) ;*.
