Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
gain yang » daun yang, tan yang, yin yang
dang hari » dang hai
yang yun » yang jun, tang yun, yang yue
dan yang » daun yang, tan yang, wang yang
yan yun » yan yuan, yan kun, yap yun
xi dang » xi kang, xi zhang

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) OR (dan yang)) xi dang hari ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang hyoung ((yan yun) or (yang yun)) ((gain yang) OR (dan yang)) xi dang hari ;~".
• Adding a wildcard symbol may retrieve word variants: lang hyoung ((yan yun) or (yang yun)) ((gain yang) OR (dan yang)) xi dang hari ;*.
