Mongolian cavalry is invincible in the world, why was it quickly wiped out by the Ming army?

Personal feeling is a very simple problem, and it is also a common problem of all foreign nationalities and non-cultivated nationalities.

You know, in our country, from ancient times to the present, the orthodoxy of the Han people is unshakable, and the dynasties that obtained state administrative ability through improper means are not praised by the world. Even the dark and decadent Ming Dynasty had a considerable number of fans compared with the Wei, Jin, Southern and Northern Dynasties. The previous novel "Those Things in the Ming Dynasty" set off the army-supporting activities of the whole Ming Dynasty history lovers, and Mingfen was once noisy. You know, there were hundreds of fans at that time. What terrible national knowledge this is, and it also proves the strength and profundity of China culture.

The first reason for the decline of Mongolian cavalry is decadence after the prosperous times. After the rule of Genghis Khan, Kublai Khan and other emperors, the incompetence of future generations could not support the prosperity of the whole Yuan Dynasty, the whole country was paralyzed, the state system could not operate, and the natural national strength would be in obvious contrast with the prosperous times. The importance of leaders is self-evident.

The second reason is the unstable foundation of the Yuan Dynasty. As grassland tribes, even if they have been rooted in the Central Plains for many years, they still lack basic farming and education. The land is planted by the Han people, who are only responsible for paying taxes. Officials are made by Han people, who are only responsible for decision-making. This leads to that once the imperial power is not strong enough, the fire of resistance will be lifted immediately, and the imperial power is in danger of being overhead at any time. It's a big no-no if you can't get along with your subjects. It's simple. Why do you want to give you Mongols the land planted by the Han people? Why don't we Han people eat beef and mutton? This is extremely unfair!

The third reason is that the composition of the Mongolian army is mostly ethnic tribes, and even a considerable part of them are Han Chinese. In addition, the Yuan Dynasty had a vast territory, so it was impossible to take care of all of them. How can we become a long-term strong army?
