Sects

Celestial Masters (Tianshi Dao)

Supreme Clarity (Shangqing)

Supreme Clarity Taoism was founded by Yang Xi in 4th century CE after he claimed to recieve mystical revalations from celestial beings, as recorded by the Shangqing Scriptures. It cares less for rituals and believes into ascenion into heaven. It split from the Celestial Masters to due elitist scholars rejecting the ritual-heavy populist practices from the Celestial Masters.

Numinous Treasure (Lingbao)

Numinous Treasure was founded by Ge Chaofu in 5th century CE and split from Supreme Clarity, disliking its elitism, instead taking heavy inspiration from Buddhist ideas including karma and rebirth and integrating those ideas with Taoist faith

Complete Perfection (Quanzhen)

Complete Perfection was a sect founded by Wang Chongyang in 12th century CE. It split from the Celestial Masters for being too ritual-heavy and dominated in northern China. Complete Perfection believes in the three teachings unity, which involves the study of Taoism, Confucianism and Buddhism.
