At the beginning of the Western Han dynasty, the system of prefectures and counties was implemented in local areas, and at the same time, the system of enfeoffment was established. Counties and countries were parallel to each other, which was not conducive to the unified management of the country, with the risk of division. The Yuan dynasty was a feudal country with a vast territory at that time. Its establishment consolidated the unification of the country and ensured the centralization of power in the system. The provincial system of the Yuan dynasty had a far-reaching influence on the political system of later generations. Since then, the provincial system has become the local administrative organ of China, which was followed in the Ming and Qing dynasties and has been retained until today.
