The Mid-Autumn Festival

In Chinese dichotomy, the sun is yang (positive, active, or male) and the moon is yin (negative, passive, or female). According to the book Chou Li, the Chou emperors (1122-249 B.C.) had the custom of praying to the moon on the 15th night of the eighth lunar month. In the Ching dynasty, there were a sun altar in eastern Peking and a moon altar in western Peking; at the time of every autumnal equinox, the emperor offered sacrifices and prayed to the moon at the moon altar.
