Wu wei in the context of "Cantong qi"

Taoism or Daoism (/ˈtaʊ.ɪzəm/ , /ˈdaʊ.ɪzəm/ ) is a philosophical and religious tradition indigenous to China, emphasizing harmony with the Tao 道 (Chinese: 道; pinyin: dào, pronounced (IPA): /tɑʊ̯/ (Chinese)). With a range of meaning in Chinese philosophy, translations of Tao include 'way', 'road', 'path', or 'technique', generally understood in the Taoist sense as an enigmatic process of transformation ultimately underlying reality. Taoist thought has informed the development of various practices within the Taoist tradition, ideation of mathematics and beyond, including forms of meditation, astrology, qigong, feng shui, and internal alchemy. A common goal of Taoist practice is self-cultivation, a deeper appreciation of the Tao, and more harmonious existence. Taoist ethics vary, but generally emphasize such virtues as effortless action, naturalness, simplicity, and the three treasures of compassion, frugality, and humility.

The core of Taoist thought crystallized during the early Warring States period (c. 450 – c. 300 BCE), during which the epigrammatic Tao Te Ching and the anecdotal Zhuangzi—widely regarded as the fundamental texts of Taoist philosophy—were largely composed. They form the core of a body of Taoist writings accrued over the following centuries, which was assembled by monks into the Daozang canon starting in the 5th century CE. Early Taoism drew upon diverse influences, including the Shang and Zhou state religions, Naturalism, Mohism, Confucianism, various Legalist theories, as well as the I Ching and Spring and Autumn Annals.

The Huainanzi is an ancient philosphical and governmental Chinese text made up of essays from scholarly debates held at the court of Liu An, Prince of Huainan, before 139 BCE. Compiled as a handbook for an enlightened sovereign and his court, the work attempts to define the conditions for a perfect socio-political order, derived mainly from a perfect ruler. With a notable Zhuangzi 'Taoist' influence, alongside Chinese folk theories of yin and yang and Wu Xing, the Huainanzi draws on Taoist, Legalist, Confucian, and Mohist concepts, but subverts the latter three in favor of a less active ruler, as prominent in the early Han dynasty before the Emperor Wu.

The early Han authors of the Huainanzi likely did not yet call themselves Taoist, and differ from Taoism as later understood. But K.C. Hsiao and the work's modern translators still considered it a 'principal' example of Han 'Taoism', retrospectively. Although the Confucians classified the text as Syncretist (Zajia), its ideas theoretically contributed to the later founding of the Taoist church in 184 c.e. Sima Tan may have even had the "subversive 'syncretism'" of the Huainanzi in mind when he coined the term Daojia ("Taoism"), claiming to "pick what is good among the Confucians and Mohists."
