Harmony-promotion" thought dates back to ancient cultures

which was originated in the tentative realization of such when our forefathers got to know the harmonious state of nature in their observation of natural phenomena while engaged in natural reconstruction. Again in their social practice

they promoted ceremonial rites and regulations to achieve harmony by the gradual accumulation of lessons and experiences

thus bringing out ceremonial rites of various kinds

such as sacrifice rites for gods

marriage rites

ancestor-worship rites

alignment rites and pilgrimage rites. These all served the purposes of easing social contradictions

seeking social harmony and helping the full growth and establishment of "harmony-promotion"thought. By the time between the end of Xizhou and the Spring and Autumn Period

"harmony-promotion" thought had undergone the state of experience toward the state of theorization

laying a profound philosophical foundation for the traditional "harmony" culture.
