hyoung gun » young eun
dang haji » dang hai, dato haji
gun guan » gan guan, gui guan, quan guan
tan ying » fan ying, tan yang, tan hong
tan yong » tan hong, tan kong, tan yang
ran ying » fan ying, jin ying, ka ying
gao ying » yao yang, fan ying, ka ying
mu dang » duc dang

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: lang hyoung gun guan ((((tan ying) OR (tan yong))) OR (((ran ying) OR (gao ying)))) mu dang haji ;~.
• Adding a wildcard symbol may retrieve word variants: lang hyoung gun guan ((((tan ying) or (tan yong))) or (((ran ying) or (gao ying)))) mu dang haji ;*.
