Warring States period in the context of "Battle of Changping"

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.

Chinese philosophy (simplified Chinese: 中国哲学; traditional Chinese: 中國哲學) refers to the philosophical traditions that originated and developed within the historical and cultural context of China. It encompasses systematic reflections on issues such as existence, knowledge, ethics, and politics. Evolving over more than two millennia, Chinese philosophy includes classical traditions such as Confucianism, Daoism, and Buddhism, as well as modern responses to Western philosophical currents. As a cultural form of philosophy, it addresses universal philosophical concerns while also reflecting the specific historical and social conditions of China.

The historical development of Chinese philosophy began during the Spring and Autumn and Warring States periods, a time known as the "Hundred Schools of Thought". Major schools such as Confucianism, Daoism, Mohism, and Legalism emerged with distinct views on human nature, social order, and political authority. During the Han dynasty, Confucianism was established as the official ideology, shaping China's intellectual and political systems for centuries. In subsequent eras, Chinese philosophy integrated influences from Indian Buddhism, giving rise to new developments such as Neo-Confucianism in the Song and Ming dynasties. In the modern period, Chinese thinkers engaged with Western thought, resulting in the emergence of Three Principles of the People, Chinese Marxism, New Confucianism, and other philosophical movements. Throughout the 20th century, these traditions were reshaped by political upheaval and continue to evolve today.

Astronomy in China has a long history stretching from the Shang dynasty, being refined over a period of more than 3,000 years. The ancient Chinese people have identified stars from 1300 BCE, as Chinese star names later categorized in the twenty-eight mansions have been found on oracle bones unearthed at Anyang, dating back to the mid-Shang dynasty. The core of the "mansion" (宿 xiù) system also took shape around this period, by the time of King Wu Ding (1250–1192 BCE).

Detailed records of astronomical observations began during the Warring States period (fourth century BCE). They flourished during the Han period (202 BCE – 220 CE) and subsequent dynasties with the publication of star catalogues. Chinese astronomy was equatorial, centered on close observation of circumpolar stars, and was based on different principles from those in traditional Western astronomy, where heliacal risings and settings of zodiac constellations formed the basic ecliptic framework. Joseph Needham has described the ancient Chinese as the most persistent and accurate observers of celestial phenomena anywhere in the world before the Islamic astronomers.

The I Ching or Yijing (Chinese: 易經 Mandarin pronunciation:[î tɕíŋ] ), usually translated Book of Changes or Classic of Changes, is an ancient Chinese divination text that is among the oldest of the Chinese classics. The I Ching was originally a divination manual in the Western Zhou period (1000–750 BCE). Over the course of the Warring States and early imperial periods (500–200 BCE), it transformed into a cosmological text with a series of philosophical commentaries known as the Ten Wings. After becoming part of the Chinese Five Classics in the 2nd century BCE, the I Ching was the basis for divination practice for centuries across the Far East and was the subject of scholarly commentary. Between the 18th and 20th centuries, it took on an influential role in Western understanding of East Asian philosophical thought.

As a divination text, the I Ching is used for a Chinese form of cleromancy known as I Ching divination in which bundles of yarrow stalks are manipulated to produce sets of six apparently random numbers ranging from 6 to 9. Each of the 64 possible sets corresponds to a hexagram, which can be looked up in the I Ching. The hexagrams are arranged in an order known as the King Wen sequence. The interpretation of the readings found in the I Ching has been discussed and debated over the centuries. Many commentators have used the book symbolically, often to provide guidance for moral decision-making, as informed by Confucianism, Taoism and Buddhism. The hexagrams themselves have often acquired cosmological significance and been paralleled with many other traditional names for the processes of change such as yin and yang and Wuxing.

The Zhou dynasty (/dʒoʊ/ JOH; Chinese: 周; pinyin: Zhōu, pronunciation: [ʈʂóʊ]) was a royal dynasty of China that existed for 789 years from c. 1046 BC until 256 BC, the longest span of any dynasty in Chinese history. During the Western Zhou period (c. 1046 – 771 BC), the royal house, surnamed Ji, had military control over territories centered on the Wei River valley and North China Plain. Even as Zhou suzerainty became increasingly ceremonial over the following Eastern Zhou period (771–256 BC), the political system created by the Zhou royal house survived in some form for several additional centuries. A date of 1046 BC for the Zhou's establishment is supported by the Xia–Shang–Zhou Chronology Project and David Pankenier, but David Nivison and Edward L. Shaughnessy date the establishment to 1045 BC.

The latter Eastern Zhou period is itself roughly subdivided into two parts. During the Spring and Autumn period (c. 771 – c. 481 BC), power became increasingly decentralized as the authority of the royal house diminished. The Warring States period (c. 475 – 221 BC) that followed saw large-scale warfare and consolidation among what had formerly been Zhou client states, until the Zhou were formally extinguished by the state of Qin in 256 BC. The Qin ultimately founded the imperial Qin dynasty in 221 BC after conquering all of China.

Fajia (Chinese: 法家; pinyin: fǎjiā), or the School of fa (incl. law, method), often translated Legalism, was a bibliographic school of primarily Warring States period classical Chinese philosophy, including more administrative works traditionally said to be rooted in Huang-Lao Daoism. Addressing practical governance challenges of the unstable feudal system, their ideas 'contributed greatly to the formation of the Chinese empire' and bureaucracy, advocating concepts including rule by law, sophisticated administrative technique, and ideas of state and sovereign power. They are often interpreted along realist lines. Though persisting, the Qin to Tang were more characterized by the 'centralizing tendencies' of their traditions.

The school incorporates the more legalistic ideas of Li Kui and Shang Yang, and more administrative Shen Buhai and Shen Dao, with Shen Buhai, Shen Dao, and Han Fei traditionally said by Sima Qian to be rooted in Huang-Lao (Daoism). Shen Dao may have been a significant early influence for Daoism and administration. These earlier currents were synthesized in the Han Feizi, including some of the earliest commentaries on the Daoist text Daodejing. The later Han dynasty considered Guan Zhong to be a forefather of the school, with the Guanzi added later. Later dynasties regarded Xun Kuang as a teacher of Han Fei and Qin Chancellor Li Si, as attested by Sima Qian, approvingly included during the 1970s along with figures like Zhang Binglin.

The Yellow Emperor, also known as the Yellow Thearch or Huangdi (traditional Chinese: 黃帝; simplified Chinese: 黄帝), was a mythical Chinese sovereign and culture hero included among the legendary Three Sovereigns and Five Emperors. He is revered as a deity individually or as part of the Five Regions Highest Deities (Chinese: 五方上帝; pinyin: Wǔfāng Shàngdì) in Chinese folk religion. Regarded as the initiator of Chinese culture, he is traditionally credited with numerous innovations – including the traditional Chinese calendar, Taoism, wooden houses, boats, carts, the compass needle, "the earliest forms of writing", and cuju, a ball game. Calculated by Jesuit missionaries, as based on various Chinese chronicles, Huangdi's traditional reign dates begin in either 2698 or 2697 BC, spanning one hundred years exactly, later accepted by the twentieth-century promoters of a universal calendar starting with the Yellow Emperor.

Huangdi's cult is first attested in the Warring States period, and became prominent late in that same period and into the early Han dynasty, when he was portrayed as the originator of the centralized state, as a cosmic ruler, and as a patron of esoteric arts. A large number of texts – such as the Huangdi Neijing, a medical classic, and the Huangdi Sijing, a group of political treatises – were thus attributed to him. Having waned in influence during most of the imperial period, in the early twentieth century Huangdi became a rallying figure for Han Chinese attempts to overthrow the rule of the Qing dynasty, remaining a powerful symbol within modern Chinese nationalism.

The Qin dynasty (/tʃɪn/ CHIN) was the first imperial dynasty of China. It is named for its progenitor state of Qin, a fief of the confederal Zhou dynasty (c. 1046–256 BC). Beginning in 230 BC, the Qin under King Ying Zheng engaged in a series of wars conquering each of the rival states that had previously pledged fealty to the Zhou. This culminated in 221 BC with the successful unification of China under Qin, which then assumed an imperial prerogative – with Ying Zheng declaring himself to be Qin Shi Huang, the first emperor of China, and bringing an end to the Warring States period (c. 475–221 BC). This state of affairs lasted until 206 BC, when the dynasty collapsed in the years following Qin Shi Huang's death. The Qin dynasty's 14-year existence was the shortest of any major dynasty in Chinese history, with only two emperors. However, the succeeding Han dynasty (202 BC – 220 AD) largely continued the military and administrative practices instituted by the Qin; as a result, the Qin have been credited as the originators of the Chinese imperial system that would endure in some form until the Xinhai Revolution in 1911.

Qin was a minor power for the first several centuries of its existence; its strength greatly increased in the 4th century BC, in large part owing to the administrative and military reforms of Shang Yang. They sought to create a strong, centralised state and a large army supported by a stable economy, which were developed in the Qin homeland and implemented across China following its unification. Reforms included the standardisation of currency, weights, measures, and the writing system, along with innovations in weaponry, transportation and military tactics.

The Bamboo Annals (Chinese: 竹書紀年; pinyin: Zhúshū Jìnián), also known as the Ji Tomb Annals (Chinese: 汲冢紀年; pinyin: Jí Zhǒng Jìnián), is a chronicle of ancient China.It begins in the earliest legendary time (the age of the Yellow Emperor) and extends to 299 BC, with the later centuries focusing on the history of the State of Wei in the Warring States period. It thus covers a similar period to Sima Qian's Records of the Grand Historian (91 BC). The original may have been lost during the Song dynasty, and the text is known today in two versions, a "current text" (or "modern text") of disputed authenticity and an incomplete "ancient text".

The clerical script (traditional Chinese: 隸書; simplified Chinese: 隶书; pinyin: lìshū), sometimes also chancery script, is a style of Chinese writing that evolved from the late Warring States period to the Qin dynasty. It matured and became dominant in the Han dynasty, and remained in active use through the Six Dynasties period. In its development, it departed significantly from the earlier scripts in terms of graphic structures (a process known as libian), and was characterized by its rectilinearity, a trait shared with the later regular script.

Although it was succeeded by the later scripts, including the regular script, the clerical script is preserved as a calligraphic practice. In Chinese calligraphy, the term clerical often refers to a specific calligraphic style that is typical of a subtype of the clerical script, the Han clerical (汉隶; 漢隸) or bafen (八分) script. This style is characterized by the squat character shapes, and its "wavy" appearance due to the thick, pronounced and slightly downward tails that are up-tilted at the ends.
