Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
yong yang » yang yang, dong yang, ying yang
sang minh » kang minah, anh minh, song ming
yang liu » yang li, yang lin, yang di
gong min » jong min, gong meng, song ming
song min » song ming, jong min, song jin
wong siu » wong shiu, kong siu, wong sau
liu liu » liu li, liu lili, lili liu
von sam » von sa, von sap, von scham

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 ((((gong min) OR (song min))) OR (sang minh)) ((wong siu) OR (von sam)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yong yang liu liu ((((gong min) or (song min))) or (sang minh)) ((wong siu) or (von sam)) ;*.
