yuan kang » yuan wang, yuan chang, chan kang
lang yan » wang yan, wang yang, zhang yan
yang hua » wang hua, yang hui, yang jui
ying hua » wang hua, ying zhu, dong hua

dan yang » daun yang, tan yang, wang yang

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 ((((yang hua) OR (ying hua))) OR (ming hua)) dan yang yuan kang (sar OR star) ;~.
• Adding a wildcard symbol may retrieve word variants: lang yan ((((yang hua) or (ying hua))) or (ming hua)) dan yang yuan kang (sar or star) ;*.
