Perhaps you should try some spelling variations:
chuan tan » chuan bang, chen tan, chuan kao
sang minh » kang minah, anh minh, song min
zhong tai » hong tan, hong hai, zhong zhi
shang hai » shang kai, dang hai, chang ha
chuan fa » chuan kao, chan fai
wan yan » wang yan, nan yan, wai yan
yan ka » yang ka, yuan kai

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 yan ka ((chuan tan) OR (chuan fa)) sang minh ((zhong tai) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ka ((chuan tan) OR (chuan fa)) sang minh ((zhong tai) or (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan ka ((chuan tan) OR (chuan fa)) sang minh ((zhong tai) or (shang hai)) ;*.
