In Tang-era mythology, Wu Gang was punished by the gods for seeking immortality and banished to the moon, where he must forever try to chop down a giant osmanthus (
桂花) tree that regrows with every stroke — a Chinese Sisyphus. Paired with Chang'e (
嫦娥) and the Jade Rabbit (
玉兔) as the canonical moon inhabitants, often referenced at Mid-Autumn Festival.
