Perhaps you should try some spelling variations:
dong ping » dong sin, dong bin, dong jung
kim kwang » kim jang
kwang hua » wang hua, wang hui
qian yan » qian jun, qian yi
dan yang » daun yang, tan yang, wang yang
yang kim » yong kim, kang kim, hyung kim
wan yan » wang yan, nan yan, wai yan
yet a » yet _, get a, set a
et a » et al, et la, e a

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) OR (qian yan))) OR (dong ping)) ((yet a) OR (et a)) dan yang kim kwang hua ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wan yan) or (qian yan))) or (dong ping)) ((yet a) or (et a)) dan yang kim kwang hua ;*.
