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

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