Perhaps you should try some spelling variations:
chuan tan » chuan bang, chen tan, chuan fa
chang mae » chang ha, changes made
yuan kai » yuan kang, yuan fei, tan kai
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
wang » wing, wan, lang

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