Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
hyoung yan » kyoung yang, hyoung gun, kyoung yun
gain yang » dan yang, yin yang
daun yang » dan yang, un yang
tan yang » dan yang, tan ying, tan yong
gang hai » dang hai, shang hai, eang hay
yan yun » yan yuan, yang yun, yan kun
xi gang » ii gang, i gang, li gang

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