What is the historical essence of China's so-called "one governance and one chaos"?

Small-scale peasant economy, the autocratic system of the unified emperor, the reason why the early dynasty was managed reasonably was because the rulers made great efforts to govern, the country recuperated and the social contradictions were small. In the later period, the court was corrupt, the land was annexed, the armament was slack, and the small-scale peasant economy was fragile (floods and droughts could cause widespread famine and uprising), which led to chaos in the world. Rebels or foreigners overthrew the former dynasty, established a new dynasty, and then made great efforts to recuperate and emigrate to pioneer. . . . If this cycle continues until the country is recovered, it can only be repeated through immigration or population extinction.

There is only one way to change the chaotic rules, and that is industrialization and foreign trade.
