Perhaps you should try some spelling variations:
japan yang » japan bank, japan can, japan change
shi japan » ii japan, shi jian, sie japan
yang mind » yang cindy, yang jin, sang minh
shang hai » shang kai, dang hai, chang ha
yuan kai » yuan kang, tan kai, yuan hui
hong hai » zhong tai, dang hai, hong tan

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