After the founding of the People's Republic of China, Qin Shihuang proclaimed himself emperor, continued to implement the Shang Yang Legalist policy since the reform of Xiaozong, strengthened the absolute monarchy, weakened the old aristocratic forces, and promoted the nobles who rose because of military achievements. The land ownership of the Qin Empire basically maintained the "Wang You" land system of the Western Zhou Dynasty and changed "Wang You" into "state-owned". After Qin Shihuang abolished the enfeoffment system, the county system and the official system were established from the central government to the local government, which were initially divided into 36 counties, and later increased to 46 counties with the expansion of land, with Xianyang (Qindu District, Xianyang City, Shaanxi Province) as its capital. In order to consolidate political power, Qin Shihuang also implemented a series of policies, mainly: unifying currency and weights and measures; Unified writing; Building the Great Wall, Equator and Straight Road; The six countries moved to enrich the people and make peace.
