yang kang » yang yang, yang guang, yang liang
kang chen » chang chen, jane chen, kang han
chen weng » chen wang, chen zheng, chen rong
kong weak » long weak, kong sek
weng yi » wong yi

• Adding a wildcard symbol may retrieve word variants: ((wing or wan) or lang) wang yang kang chen weng yi kong weak ;*.
