Perhaps you should try some spelling variations:
wang yuan » wang yuhan, wang yan, fang yuan
kai chuan » hai chuan, ka chuan, say chuan
chuan dan » chuan dato, chuan bang, chuan fa
yang mind » yang cindy, yang jin, sang minh
yuan kai » yuan kang, yuan fei, tan kai
dan yang » daun yang, tan yang, wang yang
hong » long

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