Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, hwang byoung
kang young » wang hyoung
gain yang » dan yang, daun yang, yin yang
tan yang » dan yang, tan ying, tan yong
kang hay » eang hay, kang han, dang hai
yan yun » yan yuan, yang yun, yap yun
xi kang » jin kang, xi zhang
yan kun » yan guan, yan yuan

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