Taoism originated from China in the second century. Characterized by nature worship and ancestral worship, Taoism was historically divided into many sects, which gradually evolved into two major ones-Quanzhen Taoism (Way of Completeness and Truth) and Zhengyi Taoism (Way of Orthodox Unity). Primarily, Taoism is popular among the Han people. As there are no strict rituals and rules for becoming a Taoist, statistics on believers are not available. Currently, there are more than 1,500 Taoist temples in China.
