Heibai Wuchang, or "Black and White Impermanence", are two deities in Chinese folk religion in charge of escorting the spirits of the dead to the Underworld. They are subordinates of Yama, lord of the Underworld in Vedic and Chinese mythologies. This series of digital drawings present my illustration of Wuchang the duo ("Wuchang" also means "things transient and evanescent" in Buddhism that largely influences Chinese folk religion).
