The centralization of power in the Qin Dynasty showed that the emperor was supreme and his family was in the world. The state implements the system of three public officials and nine officials. They restrict each other and are conducive to centralization. The local government has implemented the county system. The Western Han Dynasty inherited the Qin system, with gains and losses. The most important point is that the Qin dynasty adopted legalist ideology to govern the country, which was harsh and harsh and did not meet the needs of the society at that time, leading to the rapid demise of the Qin dynasty; However, after the establishment of the Han Dynasty, both Liu Bang and Wen Jing adopted Huang Lao's thought and ruled by doing nothing, and the society soon settled down. Later, after Emperor Wu of the Han Dynasty, the feudal society adopted Confucianism to govern the country and strengthened centralization.

The early Han dynasty was a system of enfeoffment in which counties and countries were in parallel. At the end of the Han Dynasty, in order to strengthen centralization, local governments set up a secretariat to supervise local governments on behalf of the central government. Politics determines the direction of the country's economic development, which leads to the ideological obstacle of culture. Compared with the ancient Qin and Han Dynasties, the politics of modern society in China developed and perfected the system and cultural thought of our ancestors on the original basis.
