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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang yan ((yan yun) or (yan yuan)) ((gain yang) OR (tan yang)) xi kang hay ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan ((yan yun) OR (yan yuan)) ((gain yang) OR (tan yang)) xi kang hay ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((yan yun) or (yan yuan)) ((gain yang) OR (tan yang)) xi kang hay ;*".
