Fulu (simplified Chinese: 符箓; traditional Chinese: 符籙), is a term for Daoist incantations and magic symbols,[1][2] written or painted as talisman or lingfu (simplified Chinese: 灵符; traditional Chinese: 靈符)[3][4][5] by Daoist practitioners.

Jiangshi are depicted in popular culture to have a paper talisman (with a sealing spell) attached onto and hanging off the forehead in portrait orientation, and wear a uniform coat-like robe and round-top tall rimmed hat characteristic of a mandarin (Chinese official from during the Qing dynasty). A peculiar feature is its greenish-white skin; one theory is that this is derived from fungus or mould growing on corpses. It is said to have long white hair all over its head[5] and may behave like animals
