Perhaps you should try some spelling variations:
hwang byoung » wang hyoung, kang young
yang yun » yang jun, yang yue, yang yang
tang yun » chang yun, fang yuan, tang chun
tan ying » fan ying, ran ying, tan yang
yan yun » yan yuan, yan kun, yap yun
ying xi » yang xi, ying jin, young xi
xi dang » xi kang, xi zhang
hai » hadi, haji, hari

You may be able to get more results by adjusting your search query.
