This term refers to the time of peace and prosperity envisioned by Confucian scholars when all the people under heaven are one family, equal, friendly, and helpful to each other (as opposed to xiaokang [小康] – moderate prosperity). Confucianism takes universal harmony as the supreme stage of the development of the human society, somewhat similar to the idea of utopia in the West. Its main features are: All power and wealth belong to the whole of society; all people are equal and live and work in peace and contentment; everyone is cared for by society; everything is used to its fullest and everyone works to his maximum potential. In the late Qing Dynasty and the early Republic of China, the term referred to the concepts of socialism, communism, or cosmopolitanism that had been introduced to China from the West.
