Perhaps you should try some spelling variations:
yuan wang » yan wang, yuan kang, yuan chang
tan chia » tuan china, than china, can china
tuan hua » tuan vu, yuan hui
yang tin » yang jin, yang jing, yang mind
yang lin » yang jin, wang lin, yang li
tan hua » wang hua, tan puay
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 ((((tan hua) OR (tan chia))) OR (tuan hua)) rene ((yang tin) OR (yang lin)) hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yuan wang ((((tan hua) or (tan chia))) or (tuan hua)) rene ((yang tin) OR (yang lin)) hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: yuan wang ((((tan hua) or (tan chia))) or (tuan hua)) rene ((yang tin) OR (yang lin)) hong yu ;*.
