Perhaps you should try some spelling variations:
chuan chuan » chen chuan, chung chuan
chang chuan » chung chuan, chen chuan, chang ch'un
yuan cheng » yuan chang, huang cheng, yu cheng
ong chong » song chong, ong cheng, hong cheng
chong ghi » hong ghi, chong yi, zhong zhi
yan chen » yun chen, jane chen, jean chen

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: (wan OR wing) qian ((yan chen) OR (yuan cheng)) ((chuan chuan) OR (chang chuan)) ong chong ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wan or wing) qian ((yan chen) or (yuan cheng)) ((chuan chuan) OR (chang chuan)) ong chong ghi ;~".
• Adding a wildcard symbol may retrieve word variants: (wan or wing) qian ((yan chen) or (yuan cheng)) ((chuan chuan) OR (chang chuan)) ong chong ghi ;*.
