What are the characteristics of the formation of the Chinese nation?

The pattern of the Chinese nation moving from pluralism to unity is gradually formed, and there is a long-term historical development process that is gradually formed.

1. First of all, its primary condensation centers are formed in various regions of China, thus forming a primary unity. For example, there were different cultural areas in the middle and lower reaches of the Yellow River in the Neolithic Age, and these cultural areas later merged to form the primary unity of Huaxia Group, the predecessor of the Han nationality.

2. Later, the vast pastoral areas outside the Great Wall were ruled by Xiongnu for a long time. As a primary unity, Xiongnu has long fought against and even fought against the Han nationality within the Great Wall. After many times in history, the northern nationalities entered the Han nationality areas in the Central Plains and the Han nationality in the Central Plains spread to the surrounding ethnic minority areas, and finally gradually merged the two primary unity of agriculture and animal husbandry inside and outside the Great Wall.

3. Later, after a long historical integration process of the flow, integration and separation of all ethnic groups, the core of exerting the greatest cohesion-the Han nationality was finally formed.

4. At the same time, Han people immigrated to non-Han areas through constant border defense and trade, forming a national connection network combining points and lines in Han and non-Han areas, organically connecting all ethnic groups on the land of China, and forming a situation of great unity of the Chinese nation.
