The Great Unity (Chinese: 大同; pinyin: dàtóng) is a Chinese utopian vision of the world in which everyone and everything is at peace. It is found in classical Chinese philosophy which has been invoked many times in the modern history of China.
The notion of the "Great Unity" appeared in the "Lǐyùn" (禮運) chapter of the Book of Rites, one of the Confucian Chinese classics. According to it, the society in Great Unity was ruled by the public, where the people chose men of virtue and ability, and valued trust and harmony. People did not only love their own parents and children, but also secured the living of the elderly until their ends, let the adults be of use to the society, and helped the young grow. Those who were widowed, orphaned, childless, handicapped and diseased were all taken care of. Men took their responsibilities and women had their homes. People disliked seeing resources being wasted but did not seek to possess them; they wanted to exert their strength but did not do it for their own benefit. Therefore, selfish thoughts were dismissed, people refrained from stealing and robbery, and the outer doors remained open.
This ideology can be reflected in the following examples, each from a national anthem of the Republic of China (Taiwan):
- 「三民主義，吾黨所宗，以建民國，以進大同。」 (literal translation: "Three Principles of the People, the aim of us, to build the Republic, to advance into Great Unity.") - National Anthem of the Republic of China
- 「毋自暴自棄，毋故步自封，光我民族，促進大同。」(literal translation: "Never abandon in desperation, nor being complacent with achievement; Glorify our nation and work promoting Great Unity.") - National Flag Anthem of the Republic of China
