Perhaps you should try some spelling variations:
gain yang » dan yang, daun yang, tan yang
yan yuan » yan guan, fang yuan, nan yan
kang hay » eang hay, kang han, dang hai
yan yun » yang yun, yap yun, tang yun
yan kun » yan guan
yang xi » yang di, yang yi, yang jui
xi kang » jin kang, xi zhang
wang » wing, wan, lang

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