The unification of the Qin dynasty ended the long-standing situation of vassal separation, which was conducive to the stability of people's lives and the development of social production, and was in line with the common aspirations of the people of all ethnic groups at that time. It laid the foundation for the establishment and development of a unified multi-ethnic country.

The territory of the Qin Dynasty extended to the sea in the east, Longxi in the west, the Great Wall in the north and the South China Sea in the south, which greatly exceeded the previous generation.

The Qin Dynasty was the first unified multi-ethnic feudal country in the history of China. It is conducive to economic development and the stable life and exchanges of people of all ethnic groups, and conforms to the wishes of people of all ethnic groups.

The Qin dynasty played a connecting role. It ended the history of slavery in China and opened a more glorious period of feudalism in China.
