Perhaps you should try some spelling variations:
chang mae » chang ha, changes made
chuan tan » chuan bang, chen tan, chuan fa
lang yan » wang yan, wang yang, zhang yan
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
yan ka » yang ka, yuan kai

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: lang yan ka chuan tan yang jin ((hong hai) OR (chang mae)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang yan ka chuan tan yang jin ((hong hai) or (chang mae)) ;*.
