kang hay » eang hay, dang hai, kang tae
kang han » kong hang, zhang han, dang hai
yang xi » yang di, yang yi, yang jui

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