Chang'e first appeared in Guicang, a divination text written in Zhou Dynasty (1046 BC - 256 BC). From the few preserved fragments of the text, it mentions "Yi shoots the ten Suns,"[1] and "Chang'e ascending to the moon."[1] Chang'e—originally named Heng'e (姮娥)—was renamed to avoid the taboo on sharing names with a deceased emperor,[2] in this case, Liu Heng, an emperor from Han Dynasty. Many Chinese poems are written around the theme of Chang'e and the moon.
