Fuji (planchette writing)

Fuji (Chinese: 扶乩; pinyin: fújī or 扶箕), often referred to as "planchette writing" or "spirit writing," is a religious practice in Chinese religions where messages from deities, ancestors, or spirits, are conveyed through a wooden or metal stylus guided by a medium or a group of participants. Fuji is a form of automatic writing that often uses a suspended sieve or tray called a planchette, which is filled with sand or incense ash where characters are written using a pen or stylus.
