Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
yang hua » wang hua, yang hui, ying hua
yang jui » yang judy, yang di, yang xi
yang jie » yang jin, yang di, yang xi
ying jin » yang jin, jing ji
yan jiu » yang jin, pang jiu
hai » hadi, haji, hari

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 hua) OR (yang jui)) ren ((((yan jiu) OR (yang jie))) OR (ying jin)) dang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ((yang hua) or (yang jui)) ren ((((yan jiu) OR (yang jie))) or (ying jin)) dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong ((yang hua) or (yang jui)) ren ((((yan jiu) OR (yang jie))) or (ying jin)) dang hai ;*.
