Perhaps you should try some spelling variations:
zhang yunling » wang yanling, zhang chunlin, zhang yuqin
kyoung hyeok » jeong hyeok
kim kyoung » kim young
yang muxi » yang jui, yang hui, yang mu
ren yong » chen yong, zhen yong, ren weng
yang yi » yang di, yang jui
yang xi » yang di, 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: zhang yunling ((((yang muxi) OR (yang yi))) OR (yang xi)) ren yong kim kyoung hyeok ;~.
• Adding a wildcard symbol may retrieve word variants: zhang yunling ((((yang muxi) or (yang yi))) or (yang xi)) ren yong kim kyoung hyeok ;*.
