Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
shi japan » ii japan, shi jian, sie japan
japan can » japan cao, japan case, japan a
shang hai » shang kai, dang hai, chang ha
zhong tai » hong tan, hong hai, zhong zhi
yang ka » yang fan, yang yao
can jin » can join, yang jin

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: yang yang ka shi japan can jin ((shang hai) OR (zhong tai)) ;~.
• Adding a wildcard symbol may retrieve word variants: yang yang ka shi japan can jin ((shang hai) or (zhong tai)) ;*.
