Marking the end of the autumn harvest, the Mid-Autumn Festival was traditionally a time to give thanks to the gods.
It is also a time of year that the moon is at its brightest, which is why lunar legends have always been attached to the celebration. Notably, the story of Chang Er, the wife of a merciless king who downed the elixir of immortality he had intended to drink, to save her people from his tyrannical rule.
The tale goes that she ascended to the moon after that, and has been worshipped by the Chinese as a Moon Goddess ever since.
