yang tang » yang yang, tang tang, nang trang
tang yun » yang yun, chang yun, fang yuan
yun gain » run gain, you gain, n gain
kang hay » kang han, dang hai, kang tae
eang hay » dang hai, kang han
yang yi » yang xi, 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 tang yun gain ((yang di) OR (yang yi)) ((kang hay) OR (eang hay)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yang tang yun gain ((yang di) or (yang yi)) ((kang hay) or (eang hay)) ;*.
