Perhaps you should try some spelling variations:
hai chuan » say chuan, ka chuan, tai chun
chuan dan » chuan dato, chuan bang, chuan fa
zhong zhi » zhang zhi, hong ghi, zhong tai
shang hai » shang kai, dang hai, chang ha
dan yang » daun yang, tan yang, wang yang
yang jin » yang jie, yang jun, ying jin
yan hai » dang hai
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 hai chuan dan yang jin ((zhong zhi) OR (shang hai)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan hai chuan dan yang jin ((zhong zhi) or (shang hai)) ;*.
