daun yang » du yang, tan yang, un yang
dan yang » tan yang, wang yang, yang yang
yan yun » yan yuan, yang yun, yan kun
xi dang » xi kang, xi zhang
wang » wing, wan, lang
hai » hadi, haji, hari

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 ((dan yang) OR (daun yang)) xi dang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang hyoung yan yun ((dan yang) or (daun yang)) xi dang hai ;*.
