What is feudalism?

Feudalism is a social ideology, that is, human consciousness determines society.

The social form on which this ideology depends is feudal society. As for the definition of "feudal society", due to the different understanding of Marxist theory of social formation, there have been differences in academic circles on whether there is a feudal society in China, when China entered the feudal society, and how to treat the differences between the feudal society in China and the feudal society in Western Europe. The academic debate on "feudalism in Western Zhou Dynasty", "feudalism in Warring States" and "feudalism in Qin and Han Dynasties" has never stopped until today.

Lv Simian, a famous historian, thinks that the Han Dynasty was the end of feudalism.
