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: lang ((yan zhang) OR (man can)) run tan yang jin ((hong hai) OR (gong meng)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang ((yan zhang) or (man can)) run tan yang jin ((hong hai) or (gong meng)) ;*.
