Perhaps you should try some spelling variations:
yuan wang » yan wang, yuan kang, yuan chang
yang tin » yang jing, yang mind, yang di
yang lin » wang lin, yang li, yang liang
yang jin » yang jie, yang jun, ying jin
tao hua » tuan hua
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 ((tao hua) OR (tan hua)) gene ((((yang tin) OR (yang lin))) OR (yang jin)) hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yuan wang ((tao hua) or (tan hua)) gene ((((yang tin) OR (yang lin))) or (yang jin)) hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: yuan wang ((tao hua) or (tan hua)) gene ((((yang tin) OR (yang lin))) or (yang jin)) hong yu ;*.
