yun gain » run gain, you gain, n gain
yang ii » yang di, yang xi, yang li
yang yi » yang di, yang xi, yang jui

• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) ((yan chang) OR (yuan chang)) yun gain ((yang ii) OR (yang yi)) dang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) ((yan chang) OR (yuan chang)) yun gain ((yang ii) or (yang yi)) dang hai ;*".
