Perhaps you should try some spelling variations:
hyung kim » yong kim
yang yang » wang yang, wang yan
hong sung » hong seung, hong song, hung sung
yan yang » yao yang, dan yang, tan yang
yang kim » yong kim, kang kim, yang di
ii rene » iii rene, i rene, wie rene
wang » wing, wan, lang

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 ((yan yang) OR (yang yang)) ii rene ((yang kim) OR (hyung kim)) hong sung ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yang) OR (yang yang)) ii rene ((yang kim) or (hyung kim)) hong sung ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan yang) OR (yang yang)) ii rene ((yang kim) or (hyung kim)) hong sung ;*.
