yuan zin » yuan lin, yuan ming, yuan ting
yang lin » yang jin, wang lin, yang li
liu gang » liu gangs, liu yang, li gang
yuan zi » yan zi, yuan li, yuan fei

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