Who first put forward the idea of "harmony is precious" in the history of China? Mencius?

it was Confucius who first put forward the idea that "harmony is precious". The origin of Confucius' thought of "harmony is precious": "Harmony is precious for courtesy. Wang Zhidao first, Sri Lanka is beautiful, and small and big. " In Confucius' view, the order of all levels of society should be governed by etiquette, and the standard of salute should be harmony. But this does not mean that everything should be followed by harmony, or be far-fetched and not bound by ceremony. In other words, above the bottom line that the hierarchical differences stipulated by etiquette cannot be broken, social relations and interpersonal communication must be based on harmony. Confucius put forward this view with the background of the times and practical significance. During the slave society, there was a serious division and opposition between all social strata, and the clear-cut boundaries could not be overstepped. The people of the upper class show their status and status by their etiquette; The people of the next class are afraid to do what they are told. However, by the Spring and Autumn Period, such social relations have gradually cracked, and the phenomenon of son killing father and minister killing monarch is not new. Therefore, Confucius began to carry out the theory of "harmony is precious", aiming at easing the contradictions among all levels of society at that time, diluting the essence of opposition between all parties, and preventing the previously stable social order from falling apart quickly. Confucius emphasized that harmony should be the foundation, and ceremony should be the instrument, which should complement each other, and should not be biased or go all the way. It can be seen that the "harmony" advocated by Confucius is not a blind remedy, but a well-thought-out knowledge in time. Source: Law and Society (17, 29)
