Perhaps you should try some spelling variations:
lang kyoung » wang hyoung, kang young, hwang byoung
kyoung tang » kyoung yang
tang yun » yang yun, chang yun, fang yuan
tan yang » tan ying, tan yong, tao yang
dan yang » daun yang, wang yang, yang yang
gang hai » dang hai, shang hai, eang hay
i gang » ii gang, li gang, yi 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 kyoung tang yun ((tan yang) OR (dan yang)) i gang hai ;~.
• Adding a wildcard symbol may retrieve word variants: lang kyoung tang yun ((tan yang) or (dan yang)) i gang hai ;*.
