Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
zhong zhi » zhang zhi, hong ghi, zhong tai
yan when » win when
can when » can women, can we, can win
sun jian » vun jian, sun japan, sun qiang
yang jie » yang jin, yang jui, yang xi
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 jian ((yang jie) OR (yang di)) ((shang hai) OR (zhong zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan when) or (can when)) sun jian ((yang jie) OR (yang di)) ((shang hai) or (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan when) or (can when)) sun jian ((yang jie) OR (yang di)) ((shang hai) or (zhong zhi)) ;*.
