daun yang » dan yang, du yang, tan yang
yang kim » yong kim, kang kim, hyung kim
dong hui » tong hui, dong hoi, gong hui
dong hua » wang hua, tong hui, dong hoi
nan yan » nan ya, wang yan, qian yan

yet a » et a, yet _, get a

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((nan yan) OR (dong yang)) yet a daun yang kim ((dong hui) OR (dong hua)) ;~.
• Adding a wildcard symbol may retrieve word variants: ((nan yan) or (dong yang)) yet a daun yang kim ((dong hui) or (dong hua)) ;*.
