daun yang » du yang, tan yang, un yang
dan yang » tan yang, wang yang, yang yang
jin kang » jin chang, jin kyung, jing fang
kang han » kang chen, kong hang, zhang han
eun shi » yun shik

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: ((wang young) OR (wang yong)) eun shi ((dan yang) OR (daun yang)) jin kang han ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang young) or (wang yong)) eun shi ((dan yang) OR (daun yang)) jin kang han ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang young) or (wang yong)) eun shi ((dan yang) OR (daun yang)) jin kang han ;*.
