Chinese Legend of The Jade Rabbit
Legend has it that there were three immortals that turned themselves into three poor old men asking a fox, monkey and rabbit for food. The fox and the monkey had food to give them, but the rabbit had none and didn't know what to do. Later, the rabbit said: "just eat me for food!" With that, the rabbit jumped into a blazing fire, making himself ready to be eaten. The immortals were deeply touched and sent the rabbit to the palace on the moon to keep Chang'e company and he was made a jade rabbit.
Jade Rabbit in Ancient Chinese Texts
An early mention that there is a rabbit on the moon appears in the Chu Ci(楚辞) - (also known as
Verses of Chu,
Songs of Chu or
Songs of the South) , a Western Han anthology of Chinese poems from the Warring States period, which notes that along with a toad, there is a rabbit on the moon who constantly pounds herbs for the immortals.
