In the People’s Republic of China, "nourishing life" (yangsheng) refers to both an ancient longevity principle and a major economic trend. On the one hand, yangsheng has been discussed from the foundational texts of Daoism as a means to attain immortality through techniques such as meditation, dietetics and calisthenics. On the other hand, "nourishing life" refers to a general idea of longevity and well-being that expresses itself in huge markets of self-help literature and wellness classes. This presentation explores how religion and the consumer-based economy merge in the form of "nourishing life training classes" (yangsheng peixun ban) held within the Medicine King Temple of Mt. Qingcheng, a sacred Daoist mountain. Anxiety about authenticity occurs both on the part of participants who fear that practices are over-commercialized and organizers who fear that too little commercialization may arouse the concern of the state that the practices are too religious in nature.
