yong yang » yang yang, dong yang, ying yang
song min » song ming, song jin, song shin
gong min » gong meng, song ming, gong si
jong min » song ming, cog min, jeong mi
cong hui » tong hui, gong hui, cong shu
xi ai » ai ai, i ai, vi ai
ii ai » ii aim, ii air, ai ai

• Adding a wildcard symbol may retrieve word variants: wang yong yang ((xi ai) or (ii ai)) ((song min) or (((gong min) or (jong min)))) cong hui ;*.
