The Jade Rabbit, also known as the "Moon Rabbit," is a popular character in Chinese folklore and is closely associated with the Mid-Autumn Festival, also known as the Moon Festival. The Mid-Autumn Festival is a traditional Chinese celebration that takes place on the 15th day of the eighth month of the lunar calendar, which usually falls in September or October.

The Jade Rabbit is said to reside on the moon and is often depicted pounding herbs or making elixirs with a mortar and pestle. The character is derived from ancient Chinese mythology and has different variations in folktales. One well-known story involves three companions: the Jade Rabbit, Wu Gang (a woodcutter), and Chang'e (the Moon Goddess).

In some versions of the legend, the Jade Rabbit is a companion to Chang'e, who was banished to the moon as a punishment. In other versions, the rabbit is known for its selfless nature, as it offers its own flesh to a beggar who turns out to be a deity in disguise testing its compassion.

During the Mid-Autumn Festival, people in China and other East Asian countries celebrate by gathering with family and friends, enjoying mooncakes, and appreciating the beauty of the full moon. The story of the Jade Rabbit is often retold during this time, adding a cultural and mythical significance to the festival. The Moon Festival is a time for reunion, gratitude, and reflection, and the Jade Rabbit plays a symbolic role in these celebrations.
