What were the signs of the formation of ancient Chinese states?

Xia Yu established the Xia Dynasty and established a complete set of state machinery, marking the formation of the country.

Before Xia Yu, under the premise of primitive public ownership, China did not have a complete concept of country and king, only the traditional concept of tribes, clans and tribal leaders. With the development of productivity, the concepts of agriculture and animal husbandry, agriculture and handicrafts emerged.

With the great division of labor, social products gradually became richer. Tribal leaders occupied more means of production through their power. The means of production transitioned from public ownership to private ownership. The national system was gradually established in this process.
