Perhaps you should try some spelling variations:
wang yuan » wang yuhan, wang yan, fang yuan
kai chuan » hai chuan, ka chuan, say chuan
shang hai » shang kai, dang hai, chang ha
yuan kai » yuan kang, yuan fei, tan kai
chuan du » chuan fa
yang jin » yang jie, yang jun, ying jin
hong hai » zhong tai, dang hai, hong a

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 yuan kai chuan du yang jin ((((hong hai) OR (hong tan))) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yuan kai chuan du yang jin ((((hong hai) OR (hong tan))) or (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yuan kai chuan du yang jin ((((hong hai) OR (hong tan))) or (shang hai)) ;*.
