Perhaps you should try some spelling variations:
kang chen » chang chen, jane chen, kang han
yang yun » yang jun, tang yun, yang yue
tan yang » dan yang, tan ying, tan yong
yang jui » yang judy, yang di, yang xi
kang hay » eang hay, kang han, dang hai
yap yun » yau yung
wang » wing, wan, lang
hyoung » young, hyong, kyoung

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 hyoung ((yap yun) OR (yang yun)) tan yang jui ((kang hay) OR (kang chen)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang hyoung ((yap yun) or (yang yun)) tan yang jui ((kang hay) or (kang chen)) ;*.
