Perhaps you should try some spelling variations:
yuan chang » yuan cheng, huang chang, han chang
yuan wang » yan wang, yuan kang, qian wang
hua rene » hua ren, juan rene
yang din » yang lin, yang dean, yang jing
yang jin » yang jie, yang jun, ying jin
tan hua » tuan hua, wang hua, tan chia
hong yu » wong yue

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) OR (yuan chang)) tan hua rene ((((yang din) OR (yang jin))) OR (yang di)) hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yuan wang) or (yuan chang)) tan hua rene ((((yang din) OR (yang jin))) or (yang di)) hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: ((yuan wang) or (yuan chang)) tan hua rene ((((yang din) OR (yang jin))) or (yang di)) hong yu ;*.
