Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song min
yang mind » yang cindy, yang jin, tang min
shang hai » shang kai, chang ha, hong hai
ka chuan » say chuan, hai chuan, ka chai
chuan du » chuan fa
yan ka » yang ka, yuan kai
wang » wing, wan, lang

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 yan ka chuan du ((yang mind) OR (sang minh)) ((shang hai) OR (dang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ka chuan du ((yang mind) OR (sang minh)) ((shang hai) or (dang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ka chuan du ((yang mind) OR (sang minh)) ((shang hai) or (dang hai)) ;*.
