Abstract: China's ancient civilization is not a unified one,but presents a situation with Yi in the east and Xia in the west.With Taihang Mountain as the boundary,Dongyi culture is distributed in the east,which is the ancient culture of the southwest minorities with the Yi ethnic group as the core today.And Huaxia culture,which is the ancient culture of the Chinese nation today,is distributed in the west.This fact has been fully and clearly demonstrated through the study of the origin of writing and archaeology.The situation of the early civilization of Yi and Xia changed with the establishment of the Xia Dynasty (about 2,070 BC-1,600 BC).After the Xia Dynasty,by determining the orthodox characters of the dynasty and redefining the world,the unified religious and political views of Chinese civilization were established.This inherent relationship between the monarch and the supreme god established by the geography and divine characters requires that the subsequent dynasty must shoulder the mission of inheriting the legacy of the previous dynasty,that is,adhering to the established and divine characters,for this is the fundamental guarantee of the legitimacy of the monarchical power.It is this political and religious tradition that has made Chinese civilization last for thousands of years.
