hong cheng » ong cheng, zong cheng, hoong chang
lang yan » wang yan, wang yang, zhang yan
yan fan » yang fan, yan clan, yan guan

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 fan hua ((zhong shang) OR (hong sheng)) a ((song so) OR (hong cheng)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan fan hua ((zhong shang) OR (hong sheng)) a ((song so) or (hong cheng)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan fan hua ((zhong shang) OR (hong sheng)) a ((song so) or (hong cheng)) ;*.
