Perhaps you should try some spelling variations:
yang yaong » yang yang, wang yang, wang yong
hua irene » hua ren
irene gan » irene a
yang yao » yang yang, wang yan, yang yi
kim song » kim young, kim eung
song ghi » hong ghi, song shin, song li
gan kim » tan kim, hwan kim, kang kim

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 ((yang yao) OR (yang yaong)) hua irene gan kim song ghi ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((yang yao) or (yang yaong)) hua irene gan kim song ghi ;*.
