Perhaps you should try some spelling variations:
japan yang » japan bank, japan can, japan change
sun japan » sino japan, can japan, men japan
zhong zhi » zhang zhi, hong ghi, zhong tai
yan when » win when
can when » can women, can we, can win
yang jui » yang judy, yang di, yang xi
hong hai » shang hai, zhong tai, dang hai

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: lang ((yan when) OR (can when)) sun japan yang jui ((hong hai) OR (zhong zhi)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang ((yan when) or (can when)) sun japan yang jui ((hong hai) or (zhong zhi)) ;*.
