Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
han chang » huang chang, than change, can change
chang yun » chong yun, chang hsun, chae yun
zhong zhi » zhang zhi, hong ghi, zhong tai
yan yang » yao yang, dan yang, tan yang
hong yu » wong yue
xi han » ti han, xi zhang
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 ((yan yang) OR (yang yang)) xi han chang yun ((zhong zhi) OR (hong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yang) OR (yang yang)) xi han chang yun ((zhong zhi) or (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan yang) OR (yang yang)) xi han chang yun ((zhong zhi) or (hong yu)) ;*.
