Wu (Chinese: 巫; pinyin: wū; Wade–Giles: wu; literally: "shaman") are spirit mediums who have practiced divination, prayer, sacrifice, rainmaking, and healing in Chinese traditions dating back over 3,000 years.
The Chinese word wu 巫 "spirit medium; shaman; shamaness; sorcerer; doctor; proper names" was first recorded during the Shang Dynasty (ca. 1600-1046 BCE), when a wu could be of either sex. During the late Zhou Dynasty (1045-256 BCE) wu was used to specify "female shaman; sorceress" as opposed to xi 覡 "male shaman; sorcerer" (which first appears in the 4th century BCE Guoyu). Other sex-differentiated shaman names include nanwu 男巫 for "male shaman; sorcerer; wizard"; and nüwu 女巫, wunü 巫女, wupo 巫婆, and wuyu 巫嫗 for "female shaman; sorceress; witch".
Wu is used in compounds like wugu 巫蠱 "sorcery; cast harmful spells", wushen 巫神 or shenwu 神巫 (with shen "spirit; god") "wizard; sorcerer", and wuxian 巫仙 (with xian "immortal; alchemist") "immortal shaman".
The word tongji 童乩 (lit. "youth diviner") "shaman; spirit-medium" is a near-synonym of wu. Chinese uses phonetic transliteration to distinguish native wu from "Siberian shaman": saman 薩滿 or saman 薩蠻. "Shaman" is occasionally written with Chinese Buddhist transcriptions of Shramana "wandering monk; ascetic": shamen 沙門, sangmen 桑門, or sangmen 喪門.
