yuan lin » duan lian, huang lin, yuan ming
liu gang » liu gangs, liu yang, li gang
yuan li » guan li, yuan zi, dayuan li
yang li » yang lin, yang di, yang xi

• Adding a wildcard symbol may retrieve word variants: wang yan ((((yuan li) or (yuan lin))) or (yang li)) liu gang pain ((long 2u) or (long 2)) ;*.
