Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
shi japan » ii japan, shi jian, six japan
sie japan » six japan, sme japan, life japan
yang mind » yang cindy, yang jin, sang minh
shang hai » shang kai, dang hai, chang ha
hong hai » zhong tai, dang hai, hong tan
yang ka » yang fan, yang yao

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 yang ka ((shi japan) OR (sie japan)) yang mind ((hong hai) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ka ((shi japan) OR (sie japan)) yang mind ((hong hai) or (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ka ((shi japan) OR (sie japan)) yang mind ((hong hai) or (shang hai)) ;*.
