kwei sheng » wei shang
tsao yuan » xiao yuan, two yuan
yuan kang » yuan wang, yuan chang, chan kang
kang kwei » wang wei, fang wei
yang jie » yang jin, yang jui, yang jun
yang xi » yang jui
yang yi » yang jui
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: tsao yuan kang kwei sheng ((((((yang xi) OR (yang jie))) OR (yang yi))) OR (yang di)) dang hai ;~.
• Adding a wildcard symbol may retrieve word variants: tsao yuan kang kwei sheng ((((((yang xi) or (yang jie))) or (yang yi))) or (yang di)) dang hai ;*.
