Perhaps you should try some spelling variations:
kai chuan » hai chuan, ka chuan, say chuan
chuan dan » chuan dato, chuan bang, chuan fa
yang mind » yang cindy, sang minh, tang min
shang hai » shang kai, dang hai, chang ha
zhong tai » hong tan, hong hai, zhong zhi
wan yuan » yan yuan, wang yuhan, fang yuan
yuan kai » yuan kang, yuan fei, tan kai
yang jin » yang jie, yang jun, ying jin

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