Perhaps you should try some spelling variations:
wang yidan » wang yan
wang ban » wang yan, wang dan, wang yang
hua rene » hua ren, juan rene
yang jin » yang jie, yang jun, ying jin
yang jui » yang judy, yang di, yang yi
wong yue » wang yue, hong yu
yang xi » yang di, 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: yuan ((wang yidan) OR (wang ban)) hua rene ((yang jin) OR (((yang xi) OR (yang jui)))) wong yue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yuan ((wang yidan) or (wang ban)) hua rene ((yang jin) or (((yang xi) OR (yang jui)))) wong yue ;~".
• Adding a wildcard symbol may retrieve word variants: yuan ((wang yidan) or (wang ban)) hua rene ((yang jin) or (((yang xi) OR (yang jui)))) wong yue ;*.
