Extended data:

Taoism believes that Taoist scriptures are sacred books written by sages with natural beauty in order to save all beings in the universe. Taoist scriptures are hidden in the "Seven Treasures Xu Antai", and immortals pass them on to Taoist celebrities by sending immortals to write, and then they spread the sermon to the whole world.

There are numerous Taoist classics, including doctrines, canon, precepts, dharma practice, fasting, preaching, geomantic calculation and so on.

Taoism takes "Tao" as its highest belief and holds that "Tao" is the source of all things. In the traditional culture of China, Taoism, together with Confucianism and Buddhism, is a dominant theory and a way to cultivate immortality.

Taoism in academic circles now refers to the ancient religious beliefs in China, which inherited most religious concepts and practice methods of Fang and Huang, as well as folk belief in gods, and gradually formed the highest belief of "Tao". It is mainly to worship the old gentleman in Taishang as the leader and take Laozi's Tao Te Ching as the classic of cultivating immortals, rather than the main sutra of cultivating truth.

As a religion in China that pursues the cultivation of immortality, the main methods of Taoist immortality can be roughly summarized into five types, namely, taking immortal medicine, external alchemy, refining qi to lead the way, cultivating inner alchemy, using Taoist instruments, self-cultivation and other rituals to achieve immortality. Later immortals mostly practiced inner alchemy, became immortals by virtue, and practiced Taoism.
