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