Perhaps you should try some spelling variations:
chuan chuan » chen chuan, chung chuan, chang chuan
when chuan » chen chuan, when can, chen chuanfu
chuan ong » chuan bang
chong ghi » hong ghi, zhong zhi
qiao can » qian yan
qiao sen » xiao ben
chong yi » chong yah, chong yun, hong yu

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: wing ((qiao can) OR (qiao sen)) when chuan chuan ong ((chong ghi) OR (chong yi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ((qiao can) OR (qiao sen)) when chuan chuan ong ((chong ghi) or (chong yi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wing ((qiao can) OR (qiao sen)) when chuan chuan ong ((chong ghi) or (chong yi)) ;*.
