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

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