Qigong originated from several areas of study including philosophy, religion, letters, the general public, and to a limited degree martial arts. In philosophy, qigong came from Dao Jia, which is the Daoist school of philosophy. In religion, qigong is found in Daoist necromancers as well as Buddhism. In the letters, it is found in Confucianism, which is the study of traditional scholars. In addition, qigong is found in fang shi, which is a type of Daoist alchemy. It would be a mistake to say qigong originated from the organized religion of Daoism.
