Each year on the 15th day of the eighth lunar month, Chinese celebrate the memory of Ch'ang O with a “Mid-Autumn Festival” (Chung-ch'iu Chieh). With a full moon shining in the heavens, “moon cakes” are eaten and offered as gifts to friends and neighbours. Many go outside to view the supposed outline of a toad on the surface of the moon, for this creature, according to one legend, is now Ch'ang O. At one time she was called Heng O, but the name became taboo when two Chinese emperors took it as their own.

A typical painting shows Ch'ang O floating toward the moon, often with her palace in the background. The Hare is sometimes present, preparing the drug of immortality. Statues more often represent her holding a moon disk in her raised right hand.
