yun gain » you gain, n gain, yun hin
run gain » run pain
yang yun » yang jun, tang yun, yang yue

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: wing qian yan ((yun gain) OR (run gain)) yang yun ((yang hui) OR (yang jui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing qian yan ((yun gain) or (run gain)) yang yun ((yang hui) OR (yang jui)) ;~".
• Adding a wildcard symbol may retrieve word variants: wing qian yan ((yun gain) or (run gain)) yang yun ((yang hui) OR (yang jui)) ;*.
