Perhaps you should try some spelling variations:
chuan tan » chuan bang, chen tan, chuan fa
sang minh » kang minah, anh minh, song min
wan yang » wang yang, dan yang, tan yang
ka chuan » say chuan, hai chuan, ka chai
tan sang » tan yang, tang tang, tan hong
hong hai » shang hai, zhong tai, hong tan
yang ka » yang fan, yang yao

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 yang ka chuan tan sang minh ((hong hai) OR (dang hai)) ;~.
• Adding a wildcard symbol may retrieve word variants: wan yang ka chuan tan sang minh ((hong hai) or (dang hai)) ;*.
