Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
hai chuan » say chuan, ka chuan, tai chun
chuan tan » chuan bang, chen tan, chuan fa
shang hai » shang kai, dang hai, chang ha
yang hai » dang hai, yang hui, yang dali
tan yong » tan hong, tan kong, tan yang
yong jin » yang jin, ying jin, song jin
hong » long

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 hai chuan tan yong jin ((shang hai) OR (hong tan)) ;~.
• Adding a wildcard symbol may retrieve word variants: yang yang hai chuan tan yong jin ((shang hai) or (hong tan)) ;*.
