Perhaps you should try some spelling variations:
hyoung yan » kyoung yang, hyoung gun, kyoung yun
yang jin » ying jin, shang jin, wang jing
yang jie » yang di, yang jui, yang xi
yang jun » yang jui, pang jun, yang judy
yan hua » tan hua, ya hua, wang hua
hua ren » hua chen
yan jiu » pang jiu
wang » wing, wan, lang

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