Perhaps you should try some spelling variations:
lang kyoung » wang hyoung, kang young, hwang byoung
wang yang » wang yan, wang liang, wang yanling
yang yun » yang jun, tang yun, yang yue
tan yang » tan ying, tan yong, tao yang
dan yang » daun yang, yang yang, adam yang
gang hai » dang hai, shang hai, eang hay
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 kyoung yang yun ((tan yang) OR (((dan yang) OR (wang yang)))) xi gang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang kyoung yang yun ((tan yang) or (((dan yang) OR (wang yang)))) xi gang hai ;~".
• Adding a wildcard symbol may retrieve word variants: lang kyoung yang yun ((tan yang) or (((dan yang) OR (wang yang)))) xi gang hai ;*.
