Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
yan when » win when
can when » can women, can we, can win
dan yang » daun yang, tan yang, wang yang
yang jie » yang jin, yang di, yang jui
hong ghi » zhong zhi, hong g, hong hai
sun dan » sun yan, sun jian
wang » wing, wan, lang

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 ((yan when) OR (can when)) sun dan yang jie ((shang hai) OR (hong ghi)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((yan when) or (can when)) sun dan yang jie ((shang hai) or (hong ghi)) ;*.
