Perhaps you should try some spelling variations:
yang kang » yang yang, yang guang, yang liang
wang yong » wang yang, wang hyoung, wang yan
tan yang » dan yang, tan ying, tan yong
kim song » kim young, kim eung
tae run » state run
run tan » run gain, run pain
li hong » le hong, li cong, li rong

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: ((yang kang) OR (wang yong)) tae run tan yang ((li hong) OR (kim song)) ghi ;~.
• Adding a wildcard symbol may retrieve word variants: ((yang kang) or (wang yong)) tae run tan yang ((li hong) or (kim song)) ghi ;*.
