qiang sun » liang sun, qian jun, wing sun
ying jin » yang jin, jing ji, yang jie
jian jie » jian ji, jian jia, huan jie
zhang li » zhang lei, zhang lin, zhang i
li qiang » li xiang, li keqiang, wei qiang
yang xi » yang yi, yang jui

• Adding a wildcard symbol may retrieve word variants: (wing or lang) ((((ying jin) or (yang di))) or (yang xi)) jian jie zhang li qiang sun ;*.
