Abstract: The origin of Chinese civilization and "the earliest China" are two different propositions. The so-called "the origin of Chinese civilization" or "the origins of China's state" explores the origin of civilization or the origin of the country in present China. The so-called "original China" is about what the concept of China originally meant, how it emerged, and how it evolved into what we now call China. Through textual research, we find that the initial emergence of the concept of China is closely related to the structure of the "composite system of a composite dynasty". The "Chinese people", as mentioned in the article, is related to the emergence of China and the emergence of the Xia Dynasty and the formation of the Chinese nation. In other words, in the composite national structure, the dynasty and the "world" have the identity; The political center of the dynasty is the capital, which is identical with the so-called "the earth" and "China". Hence we say that the concept of China has experienced such an evolution.
