Chinese ritual mastery traditions, also referred to as ritual teachings (, sometimes rendered as "Faism"), or Folk Taoism (), or also Red Taoism (mostly in east China and Taiwan), constitute a large group of Chinese orders of ritual officers who operate within the Chinese folk religion but outside the institutions of official Taoism. The "masters of rites", the fashi (法師), are also known in east China as hongtou daoshi (紅頭道士), meaning "redhead" or "redhat" daoshi ("masters of the Tao"), contrasting with the wutou daoshi (烏頭道士), "blackhead" or "blackhat" priests, of Zhengyi Taoism who were historically ordained by the Celestial Master.
Zhengyi Taoism and Faism are often grouped together under the category of "daoshi and fashi ritual traditions" (道法二門道壇). Although the two types of priests have the same roles in Chinese society—in that they can marry and they perform rituals for communities' temples or private homes—Zhengyi daoshi emphasize their Taoist tradition, distinguished from the vernacular tradition of the fashi.
Ritual masters can be practitioners of tongji possession, healing, exorcism and jiao rituals (although historically they were excluded from performing the jiao liturgy). The only ones that are shamans (wu) are the fashi of the Lushan school.
The ritual masters (法師 fashi) are defined, in opposition to formally ordained Taoist priests, as:
Lay practitioners beyond formal organisations whose lineages are vocational rather than hereditary. They live in the communities or among the families they serve or travel through villages and towns of the country, performing exorcisms, establishing protection, and effecting cures among the populace.
Sarah Coakley (Cambridge University) distinguishes fashi as "kataphatic" (of filling character) in opposition to Taoists as "kenotic" (of emptying character), and links them to other Sino-Tibetan indigenous religions:
resemble or make use of Taoist texts and visualisation, but are not truly Taoist; i.e., they are not kenotic or emptying in character, but rather kataphatic or filling with lesser spirits and local phenomena of nature.
