Guanzhong reform refers to the internal affairs reform, the development of production, the reform of the military system and the expansion of the army in the middle of the 7th century BC. Through these actions, Huan Gong became the first overlord in the Spring and Autumn Period.

In fact, these reforms have not touched the social system, but within slavery, the land will still be owned by the state or nobles.

The reform of Shang Yang and others refers to the reform of the feudal landlord class, that is, the state recognizes the private ownership of land and allows free trading. The ruling class changed from slave owners and nobles to landlords. In Qin Wei, for example, anyone can get rid of the corvee through military service, acquire land, and then become the ruling class.
