Spring and Autumn Annals in the context of "Five Classics"

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 Spring and Autumn period (c. 770 – c. 481 BCE) was a period in Chinese history corresponding roughly to the first half of the Eastern Zhou (c. 771 – 256 BCE), characterized by the gradual erosion of royal power as local lords nominally subject to the Zhou exercised increasing political autonomy. The period's name derives from the Spring and Autumn Annals, a chronicle of the state of Lu between 722 and 481 BCE, which tradition associates with Confucius (551–479 BCE).

During this period, local polities negotiated their own alliances, waged wars against one another, up to defying the king's court in Luoyi. The gradual Partition of Jin, one of the most powerful states, is generally considered to mark the end of the Spring and Autumn period and the beginning of the Warring States period. The periodization dates to the late Western Han (c. 48 BCE – 9 CE).

The Zuo Zhuan (Chinese: 左傳; Wade–Giles: Tso Chuan; [tswò ʈʂwân]), often translated as The Zuo Tradition or as The Commentary of Zuo, is an ancient Chinese narrative history traditionally regarded as a commentary on the ancient Chinese chronicle Spring and Autumn Annals. It comprises 30 chapters that cover the period from 722 to 468 BC, and it focuses mainly on the Chinese political, diplomatic, and military affairs from that era.

For many centuries, the Zuo Zhuan was the primary text through which educated Chinese learned their ancient history. The Zuo Zhuan does not simply explain the wording of the Spring and Autumn Annals, but rather expounds upon its historical background with rich and lively accounts of the history and culture of the Spring and Autumn period (771–476 BC). The Zuo Zhuan is the source of more Chinese sayings and idioms than any other classical work, and its concise, flowing style served as a paragon of elegant Classical Chinese. Its tendency toward third-person narration and portraying characters through direct speech and action became hallmarks of Chinese narrative in general, and its style was imitated by historians, storytellers, and ancient-style prose masters for over 2000 years of subsequent Chinese history.
