Wuxing (Chinese philosophy) in the context of "Zhou Dunyi"

The history of China spans several millennia across a wide geographical area. Each region now considered part of the Chinese world has experienced periods of unity, fracture, prosperity, and strife. Chinese civilization first emerged in the Yellow River valley, which along with the Yangtze basin constitutes the geographic core of the Chinese cultural sphere. China maintains a rich diversity of ethnic and linguistic people groups. The traditional lens for viewing Chinese history is the dynastic cycle: imperial dynasties rise and fall, and are ascribed certain achievements. This lens also tends to assume Chinese civilization can be traced as an unbroken thread many thousands of years into the past, making it one of the cradles of civilization. At various times, states representative of a dominant Chinese culture have directly controlled areas stretching as far west as the Tian Shan, the Tarim Basin, and the Himalayas, as far north as the Sayan Mountains, and as far south as the delta of the Red River.

The Neolithic period saw increasingly complex polities begin to emerge along the Yellow and Yangtze rivers. The Erlitou culture in the central plains of China is sometimes identified with the Xia dynasty (3rd millennium BC) of traditional Chinese historiography. The earliest surviving written Chinese dates to roughly 1250 BC, consisting of divinations inscribed on oracle bones. Chinese bronze inscriptions, ritual texts dedicated to ancestors, form another large corpus of early Chinese writing. The earliest strata of received literature in Chinese include poetry, divination, and records of official speeches. China is believed to be one of a very few loci of independent invention of writing, and the earliest surviving records display an already-mature written language. The culture remembered by the earliest extant literature is that of the Zhou dynasty (c. 1046 – 256 BC), China's Axial Age, during which the Mandate of Heaven was introduced, and foundations laid for philosophies such as Confucianism, Taoism, Legalism, and Wuxing.

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 Han dynasty (202 BCE – 220 CE) was a period of Imperial China divided into the Western Han (202 BCE – 9 CE) and Eastern Han (25–220 CE) periods, when the capital cities were located at Chang'an and Luoyang, respectively. It was founded by Emperor Gaozu of Han and briefly interrupted by the regime of Wang Mang (r. 9–23 CE) who usurped the throne from a child Han emperor.

The Han dynasty was an age of great economic, technological, cultural, and social progress in China. Its society was governed by an emperor who shared power with an official bureaucracy and semi-feudal nobility. Its laws, customs, literature, and education were largely guided by the philosophy and ethical system of Confucianism, yet the influence of Legalism and Daoism (from the previous Zhou dynasty) could still be seen. Members of the scholarly-gentry class who aspired to hold public office were required to receive a Confucian-based education. A new synthetic ideology of Han Confucianism was created when the scholar Dong Zhongshu (179–104 BCE) united the Confucian canon allegedly edited by Kongzi, or Confucius (551–479 BCE), with cosmological cycles of yin and yang and the Chinese five elements.

Dong Zhongshu (Chinese: 董仲舒; Wade–Giles: Tung Chung-shu; 179–104 BC) was a Chinese philosopher, politician, and writer of the Han dynasty. He is traditionally associated with the promotion of Confucianism as the official ideology of the Chinese imperial state, favoring heaven worship over the tradition of cults celebrating the five elements. Enjoying great influence in the court in the last decades of his life, his adversary Gongsun Hong ultimately promoted his partial retirement from political life by banishing him to the Chancellery of Weifang, but his teachings were transmitted from there.

Chinese astrology is based on traditional Chinese astronomy and the Chinese calendar. Chinese astrology flourished during the Han dynasty (2nd century BC to 2nd century AD).

Chinese astrology has a close relation with Chinese philosophy (theory of the three harmonies: heaven, earth, and human), and uses the principles of yin and yang, wuxing (five phases), the ten Heavenly Stems, the twelve Earthly Branches, the lunisolar calendar (moon calendar and sun calendar), and the time calculation after year, month, day, and shichen (時辰, double hour). These concepts are not readily found or familiar in Western astrology or culture.
