yuan hui » yuan fei, jaan hui, tuan hua
hui rana » hui yang
yang jin » yang jie, yang jun, ying jin
li yuan » liu yuan, li quan, li yun
yang xi » yang di, yang jui

• If you are trying to use Boolean operators, they must be ALL CAPS: tang li yuan hui rana ((((yang jin) OR (yang xi))) OR (yang yi)) ((cong shu) OR (dong sign)) ;~.
• Adding a wildcard symbol may retrieve word variants: tang li yuan hui rana ((((yang jin) or (yang xi))) or (yang yi)) ((cong shu) or (dong sign)) ;*.
