Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
yang yun » yang jun, tang yun, yang yue
tan yang » dan yang, tan ying, tan yong
yan yun » yan yuan, yan kun, yap yun
yang xi » yang di, yang yi, yang jui
xi dang » xi kang, xi zhang
hai » hadi, haji, hari

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 ((yan yun) OR (yang yun)) tan yang xi dang hai ;~.
• Adding a wildcard symbol may retrieve word variants: lang hyoung ((yan yun) or (yang yun)) tan yang xi dang hai ;*.
