Perhaps you should try some spelling variations:
zhong zhi » zhang zhi, hong ghi, zhong tai
jian yang » qian yan, dan yang, jia fang
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 di, yang jui
hong hai » shang hai, zhong tai, dang hai
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 ((hong 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 ((hong hai) or (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan when) OR (can when)) sun jian yang jie ((hong hai) or (zhong zhi)) ;*.
