Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
binh kang » binh thang, jin kang
song sein » song shin, song jin, song min
yang dii » yang dali, yang zili, yang jui
kang kim » kanaga kim, tan kim, yong kim
kim song » kim young, kim eung
yang yi » yang jui
yang xi » yang jui

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: lang hyoung ((yang dii) OR (((((yang di) OR (yang yi))) OR (yang xi)))) binh kang kim song sein ;~.
• Adding a wildcard symbol may retrieve word variants: lang hyoung ((yang dii) or (((((yang di) or (yang yi))) or (yang xi)))) binh kang kim song sein ;*.
