Wu Gang

Wu Gang, formerly romanized as Wu Kang and also known as Wu Zhi in some sources, is a figure in traditional Chinese folklore and religion. He is known for endlessly cutting down a self-healing osmanthus tree on the Moon, a divine punishment which has led to his description as the Chinese Sisyphus. In modern Chinese, the chengyu "Wu Gang chopping the tree" (; wúgāng-fáguì) is used to describe any endless toil. The specific reason for his situation has varied in the sources, but Wu Gang's story dates back to at least the Tang dynasty.
