How to comprehensively evaluate the ancient Chinese emperor system?

China is too big, unlike those small city-states in ancient Greece, so they gave birth to the embryonic form of national democracy, and we gave birth to the feudal monarchy. For the emperor system, centralization was not strong at first, such as feudalism and the chaos of the seven countries in the Han Dynasty, so the emperor system must strengthen centralization to strengthen its rule, so the emperor system developed in this way and reached its peak in the Qing Dynasty. This autocratic system only serves one interest, that is, the landlord, but the landlord class does not occupy much space in China society. In addition, in order to safeguard their own interests, they conflict with the interests of other classes. This is for sure, because various interests are actually in conflict. When one kind of interest is obviously higher than other interests, then this kind of interest will be hostile, and when this kind of interest is considerable, internal interest disputes will occur. This is the so-called regime change, the root of the court struggle. At the same time, the interests of other classes will be ready to move. At this time, the emperor will strengthen cultural and ideological education, such as Confucianism respected in ancient times. In fact, it is to safeguard the interests of slave owners. This method really works, imprisoning China people for thousands of years, so the emperor system has caused unimaginable obstacles to China's cultural progress. As for promoting the development of historical trends, it is only that future generations can't define or show helplessness when looking at history, because China people must find a suitable statement for their national history. . . . . . . . . .
