Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
yong yang » yang yang, dong yang, kyoung yang
kong star » kong sar
chen yan » chen yang, chen siyan, chen yanni
long shu » wong sau
yang xi » yang di, yang yi, yang jui
xi chen » yi chen, jui chen
yan jiu » yang jin

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 xi chen yan jiu ((long shu) OR (kong star)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yong yang xi chen yan jiu ((long shu) or (kong star)) ;*.
