Though specific religious aspects are not mentioned in the Dao De Jing or Zhuang Zi, as Taoism spread through the population of China it became mixed with other, pre-existing beliefs, such as Five Elements theory, alchemy, ancestor worship, and magic spells. Chinese Chan Buddhism was also directly influenced by Taoist philosophies. Eventually elements of Taoism were combined with elements of Buddhism and Confucianism in the form of Neo-Confucianism. Attempts to procure greater longevity were a frequent theme in Taoist alchemy and magic, with many extant spells and potions for that purpose. Many early versions of Chinese medicine were rooted in Taoist thought, and modern Chinese medicine as well as Chinese martial arts are still in many ways concerned with Taoist concepts such as Tao, Qi, and the balance of Yin and Yang.
In addition, a Taoist church was formed, originally being established in the Eastern Han dynasty by Zhang Daoling. Many sects evolved over the years, but most trace their authority to Zhang Daoling, and most modern Taoist temples belong to one or another of these sects. The Taoist churches incorporated entire pantheons of deities, including Lao zi, Zhang Daoling, the Yellow Emperor, the Jade Emperor, Lei Gong (The God of Thunder) and others. The two major Taoists churches today are the Zhengyi Sect (evolved from a sect founded by Zhang Daoling) and Quanzhen Taoism (founded by Wang Chongyang).
