Perhaps you should try some spelling variations:
chuan dong » chuan bang
dong hoang » hong hong
yang yang » wang yang, wang yan
hoang jin » huang jing, shang jin, yang jin
shang hai » shang kai, dang hai, chang ha
ka chuan » say chuan, hai chuan, ka chai
hong hai » zhong tai, dang hai, 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: yang yang ka chuan dong hoang jin ((hong hai) OR (shang hai)) ;~.
• Adding a wildcard symbol may retrieve word variants: yang yang ka chuan dong hoang jin ((hong hai) or (shang hai)) ;*.
