What are the basic characteristics of ancient Chinese legal system?

Let's talk in general terms, there are too many details:

The traditional legal system in China is characterized by the combination of etiquette and law, but the formation of this feature is not achieved overnight.

The Western Zhou Dynasty is the origin of this traditional feature.

During the Spring and Autumn Period and the Warring States Period, the ceremony collapsed and the Legalist thought dominated.

The legal system of the Qin Dynasty was guided by legalist thought.

Han inherited the Qin system, and the legal system was legalist. However, in the early Han dynasty, the thought was "Huang Lao" (ruling by doing nothing), and Emperor Wu of the Han Dynasty ousted hundreds of schools and respected Confucianism alone. Under this influence, the law that embodies the legalist thought began the process of Confucianism.

The legal system of Wei, Jin, Southern and Northern Dynasties was further Confucian;

During the Sui and Tang Dynasties, Confucianism finally came to fruition —— On the Tang Law.
