Perhaps you should try some spelling variations:
chang chuan » chung chuan, chen chuan, chang ch'un
cheng ping » chen ping, cheng ling, cheng ming
cheng bing » cheng ling, cheng ming, chen ping
kang young » wang hyoung
han chang » huang chang, than change, can change
kong siu » kong eiu, wong siu, dong sin
yan han » man han, yan zhang, kang han

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: yan han chang chuan ((cheng ping) OR (cheng bing)) lin ((kong siu) OR (kang young)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yan han chang chuan ((cheng ping) OR (cheng bing)) lin ((kong siu) or (kang young)) ;~".
• Adding a wildcard symbol may retrieve word variants: yan han chang chuan ((cheng ping) OR (cheng bing)) lin ((kong siu) or (kang young)) ;*.
