What changes have taken place in Chinese society during the Yellow Emperor period?

From the Yellow Emperor to Shun, it was a primitive clan society. Its main feature is to use public tools, work together and distribute food together. There is no difference between the rich and the poor.

When the Xia Dynasty was established in Xia Qi, due to the development of social productivity and division of labor and the improvement of labor productivity, workers were able to produce surplus products, so it was profitable to enslave others. In this case, the first form of human exploitation appeared in human history, that is, slave society.

The Western Zhou Dynasty began to enter the feudal society. As far as its original interpretation is concerned, the word "feudal society" should refer to its literal meaning: sealing the country. That is, under the feudal Lord system, the Lord (also known as the feudal Lord) is the person who holds power in a region, the landlord in economy and the ruler in politics. Under the feudal landlord system, landlords only occupied land economically, but politically centralized, and bureaucrats appointed by the central government ruled the place.
