Perhaps you should try some spelling variations:
chuan yang » chuan bang, chen yang, huang yang
wang yang » wang yan, wang yanling
yang yang » wang yan
shang hai » shang kai, dang hai, chang ha
ka chuan » say chuan, hai chuan, ka chai
yang jin » yang jie, yang jun, ying jin
hong hai » zhong tai, dang hai, hong tan

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