What are the stages of traditional culture in China?

Different schools have different views, but they all think that Qin is a previous stage, which is called pre-Qin culture.

After the Qin Dynasty, it was generally believed that the Han and Tang Dynasties were a stage and the Song Dynasty was a stage. Yuan, Ming and Qing Dynasties were each a stage.

In my opinion, after the Qin Dynasty, the cultures of different dynasties were different and could not be unified by induction. It can only be a cultural stage of a dynasty, during which there was not much contact, and even some places were still dating.
