Perhaps you should try some spelling variations:
chung chuan » chen chuan
chuan ong » chuan bang
can chen » can china, jean chen, tan cheng
can when » can women, can we, can win
chong yi » chong yah, chong yun, hong yu
hong hai » shang hai, zhong tai, dang hai
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) qiao ((can chen) OR (can when)) chung chuan ong ((chong yi) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) qiao ((can chen) OR (can when)) chung chuan ong ((chong yi) or (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) qiao ((can chen) OR (can when)) chung chuan ong ((chong yi) or (hong hai)) ;*.
