Perhaps you should try some spelling variations:
wan kyoung » wang hyoung, han kyung, hwang byoung
yang qui » yang hui, yang muxi, yang di
wang wei » zhang wei, wang zhi
yang jin » yang jie, yang jun, ying jin
yang jui » yang judy, yang di, yang xi
yan jiu » yang jie, pang jiu
hong ng » hong kong, hong jong, hong hong

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: wan kyoung ((yang qui) OR (wang wei)) regne ((((yan jiu) OR (yang jin))) OR (yang jui)) hong ng ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan kyoung ((yang qui) or (wang wei)) regne ((((yan jiu) OR (yang jin))) or (yang jui)) hong ng ;~".
• Adding a wildcard symbol may retrieve word variants: wan kyoung ((yang qui) or (wang wei)) regne ((((yan jiu) OR (yang jin))) or (yang jui)) hong ng ;*.
