Black & White Wuchang are two deities in charge of escorting the spirits of the dead to the Underworld.They are worshiped as fortune deities and are represented as a single being - known as the Wuchang Ghost, literally "Ghost of Impermanence". Depending on the person it encounters, the Wuchang Ghost can appear as either a fortune deity who rewards the person for doing good deeds or a malevolent deity who punishes the person for committing evil.
The White Ghost on the front side is the snow-fair complexioned man wearing a tall hat bearing the words "Become Rich Upon Encountering Me" (一見發財 / 一見生財), "Become Lucky Upon Encountering Me" (一見大吉). The Black Ghost is typically represented as a dark complexioned man wearing a hat bearing the words "Peace to the World" (天下太平). The ferocious snarls on their faces and long red tongue sticking out the mouth to scare away evil spirits.
