Perhaps you should try some spelling variations:
song myung » song byung, sung myung, song ming
myung koo » byung kook, myung won
yang jui » yang judy, yang yi
yang jun » pang jun, yang jin, yang judy
kyu song » kyu sung, hyun song, kim song
koo kong » koo kang
wan yan » wang yan, nan yan, wai yan
yang xi » yang yi

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: wan yan ((((((yang jui) OR (yang xi))) OR (yang di))) OR (yang jun)) kyu song myung koo kong ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan ((((((yang jui) or (yang xi))) or (yang di))) or (yang jun)) kyu song myung koo kong ;*.
