Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
yao chuan » say chuan, hai chuan
chang mae » chang ha, changes made
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 ((yao chuan) OR (ka chuan)) tan yang jin ((hong hai) OR (chang mae)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang yang ((yao chuan) OR (ka chuan)) tan yang jin ((hong hai) or (chang mae)) ;~".
• Adding a wildcard symbol may retrieve word variants: yang yang ((yao chuan) OR (ka chuan)) tan yang jin ((hong hai) or (chang mae)) ;*.
