yan congo » yan cong
congo yun » chong yun, cong sun, congo can
yun gain » run gain, you gain, n gain
yang jun » yang jui, pang jun, yang jin
wai yan » wang yan, wei yang

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: wai yan congo yun gain ((((((yang judy) OR (yang jun))) OR (yang yi))) OR (yang di)) long grain ;~.
• Adding a wildcard symbol may retrieve word variants: wai yan congo yun gain ((((((yang judy) or (yang jun))) or (yang yi))) or (yang di)) long grain ;*.
