Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
gain yang » dan yang, daun yang, tan yang
zhang hai » zhang dai, shang hai, zhang han
yang yun » yang jun, tang yun, yang yue
xi zhang » li zhang, xiao zhang, bin zhang
yan yun » yan yuan, yan kun, yap yun
yang xi » yang di, yang yi, 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: lang hyoung ((yan yun) OR (yang yun)) gain yang xi zhang hai ;~.
• Adding a wildcard symbol may retrieve word variants: lang hyoung ((yan yun) or (yang yun)) gain yang xi zhang hai ;*.
