The Great Harmony (大同, Datong) is an ideal social order envisioned by classical Chinese Confucianism in the 6th century BCE. Receiving its first systematic exposition in The Book of Rites (禮記, Liji), specifically within the chapter 'The Conveyance of Rites,' its core philosophical bedrock is the principle that 'The World Belongs to the Public' (天下爲公, Tianxia Wei Gong).
This concept advocates for the public ownership of power, rejects hereditary systems (世袭, Shixi), and promotes a strict meritocracy by selecting the "worthy and capable" (選賢與能, Xuǎn). Economically, it advocates the public ownership of goods and wealth, emphasizes that all members of society fulfill their respective duties, ensures that the elderly, the weak, orphans, and widows are cared for, and aims to construct a public order characterized by equality and mutual assistance for all.
Pre-Qin Confucians (before 221 BCE) regarded it as an institutional design opposing monarchical power and advocating that power be chosen by the people. Han Confucians (202 BCE to 220 CE) cited the Abdication of Yao and Shun as examples but still did not depart from the framework of monarchical designation. During the Sui and Tang dynasties (581 to 907 CE), the principle of "selecting the worthy and capable" gradually evolved into the Imperial Examination System, deviating from the initial concept of popular election. Neo-Confucianism elevated its ethical principles into the philosophical concept of "The Unity of All Things." In modern times, Kang Youwei proposed a vision of an egalitarian society in The Book of Great Harmony (1885-1902), and Sun Yat-sen integrated his Three Principles of the People (1906) with this concept. This concept was later incorporated into the theory of Socialism with Chinese Characteristics (SWCC), first coined by Deng Xiaoping in 1982, and into the official ideological framework of the Communist Party of China (CPC), becoming a significant intellectual resource of contemporary Chinese civilization.
