Perhaps you should try some spelling variations:
yang yang » wang yan
wang yang » wang yan, wang liang, wang yanling
chuan tan » chuan bang, chen tan, chuan fa
ka chuan » say chuan, hai chuan, ka chai
tan yang » dan yang, tan ying, tan yong
yang jin » yang jie, yang jun, ying jin
hong hai » shang hai, zhong tai, dang hai

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