Anyang in the context of "Shang dynasty"

Chinese characters are logographs used to write the Chinese languages and others from regions historically influenced by Chinese culture. Of the four independently invented writing systems accepted by scholars, they represent the only one that has remained in continuous use. Over a documented history spanning more than three millennia, the function, style, and means of writing characters have changed greatly. Unlike letters in alphabets that reflect the sounds of speech, Chinese characters generally represent morphemes, the units of meaning in a language. Writing all of the frequently used vocabulary in a language requires roughly 2000–3000 characters; as of 2025, more than 100000 have been identified and included in The Unicode Standard. Characters are created according to several principles, where aspects of shape and pronunciation may be used to indicate the character's meaning.

The first attested characters are oracle bone inscriptions made during the 13th century BCE in what is now Anyang, Henan, as part of divinations conducted by the Shang dynasty royal house. Character forms were originally ideographic or pictographic in style, but evolved as writing spread across China. Numerous attempts have been made to reform the script, including the promotion of small seal script by the Qin dynasty (221–206 BCE). Clerical script, which had matured by the early Han dynasty (202 BCE – 220 CE), abstracted the forms of characters—obscuring their pictographic origins in favour of making them easier to write. Following the Han, regular script emerged as the result of cursive influence on clerical script, and has been the primary style used for characters since. Informed by a long tradition of lexicography, states using Chinese characters have standardized their forms—broadly, simplified characters are used to write Chinese in mainland China, Singapore, and Malaysia, while traditional characters are used in Taiwan, Hong Kong, and Macau.

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.

Oracle bone script is the oldest attested form of written Chinese, dating to the late 2nd millennium BC. Inscriptions were made by carving characters into oracle bones, usually either the shoulder bones of oxen or the plastrons of turtles. The writings themselves mainly record the results of official divinations carried out on behalf of the Late Shang royal family. These divinations took the form of scapulimancy where the oracle bones were exposed to flames, creating patterns of cracks that were then subjected to interpretation. Both the prompt and interpretation were inscribed on the same piece of bone that had been used for the divination itself.

Out of an estimated 150,000 inscriptions that have been uncovered, the vast majority were unearthed at Yinxu, the site of the final Shang capital (modern-day Anyang, Henan). The most recent major discovery was the Huayuanzhuang cache found near the site in 1993. Of the 1,608 Huayuanzhang pieces, 579 bear inscriptions. Each of the last nine Shang kings are named in the inscriptions beginning with Wu Ding, whose accession is variously dated between 1250 and 1200 BC. Oracle bone inscriptions corresponding to Wu Ding's reign have been radiocarbon dated to 1254–1197 BC (±10 years). Following the overthrow of the Shang by the Zhou dynasty in c. 1046 BC, divination using milfoil became more common; far fewer oracle bone inscriptions are dated to the Western Zhou. No Zhou-era sites with a comparable cache of inscriptions to Yinxu have been found; however, examples from this period appear to be more widespread, having been found near most major population centers. New sites have continued to be discovered since 2000.

Wu Ding (Chinese: 武丁; died c. 1192 BC); personal name Zi Zhao (子昭), was a king of the Chinese Shang dynasty who ruled the central Yellow River valley. He is the earliest figure in Chinese history mentioned in contemporary records. The annals of the Shang dynasty compiled by later historians were once thought to be little more than legends until oracle script inscriptions on bones dating from his reign were unearthed at the ruins of his capital Yin (near modern Anyang) in 1899. Oracle bone inscriptions from his reign have been radiocarbon dated to 1254–1197 BC ±10 years, closely according with regnal dates derived by modern scholars from received texts, epigraphic evidence, and astronomical calculations.

Wu Ding's reign is characterized by a prosperous period of the late Shang state, with a wide network of allies and subordinates. The first inscriptions unequivocally recognized as Chinese appeared during his reign, together with new technological innovations. More than half of Shang inscriptions date to his reign, concerning a wide variety of deities. In classical Chinese historiography, he is often depicted as a meritorious king.

The Late Shang, also known as the Anyang period, is the earliest known literate civilization in China, spanning the reigns of the last nine kings of the Shang dynasty, beginning with Wu Ding in the second half of the 13th century BC and ending with the conquest of the Shang by the Zhou in the mid-11th century BC. The state is known from artifacts recovered from its capital at a site near Anyang now known as Yinxu and other sites across the North China Plain. One of the richest finds was the Tomb of Fu Hao at Yinxu, thought to belong to a consort of Wu Ding mentioned in Shang inscriptions.

Most Shang writing takes the form of inscriptions on oracle bones used for divinations on behalf of the king. Shang ritual focused on offerings to ancestors, enabling modern investigators to deduce a king list that largely matches that of the traditional histories of Sima Qian and the Bamboo Annals. The inscriptions also give insight into royal concerns such as weather, the harvest, warfare with neighbouring polities, and mobilizing workers for warfare or agricultural work.
