Perhaps you should try some spelling variations:
chang chuan » chung chuan, chen chuan, chang ch'un
han chuan » hai chuan, chen chuan, say chuan
kong heng » kong hang, kong hong, dong sheng
qiao yan » qian yan, jiao yan, xiao yuan
yan kang » yuan kang, yan wang, yang yang
wang » wing, wan, lang
hong » long

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 qiao yan kang ((han chuan) OR (chang chuan)) ((kong heng) OR (hong kong)) zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang qiao yan kang ((han chuan) OR (chang chuan)) ((kong heng) or (hong kong)) zhi ;~".
• Adding a wildcard symbol may retrieve word variants: wang qiao yan kang ((han chuan) OR (chang chuan)) ((kong heng) or (hong kong)) zhi ;*.
