jin kang » jin chang, jin kyung, jing fang
yan yun » yan yuan, yang yun, yan kun

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