Perhaps you should try some spelling variations:
jian yang » qian yan, dan yang, jia fang
zhong tai » hong tan, zhong zhi
yan when » win when
can when » can women, can we, can win
sun jian » vun jian, sun japan, sun qiang
hong hai » shang hai, dang hai, hong tan
wang » wing, 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 OR wan) ((yan when) OR (can when)) sun jian yang judy ((hong hai) OR (zhong tai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) ((yan when) OR (can when)) sun jian yang judy ((hong hai) or (zhong tai)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) ((yan when) OR (can when)) sun jian yang judy ((hong hai) or (zhong tai)) ;*.
