Why was the Ming Dynasty unable to completely control Mongolia for the rest of its life?

Because Mongolia wants to return to the peak of the Yuan Dynasty, even if its strength is very weak, it will not compromise with the Ming Dynasty, so the Ming Dynasty cannot control Mongolia, and can only slowly consume his strength.

I think the main reason is that the rulers of the Ming Dynasty at that time wanted to construct a prosperous era for themselves not to fight, and the result that the strength of the Ming Dynasty was not very strong.

That's because the conditions at that time were relatively harsh, and secondly, because the command staff was problematic, so this situation occurred.

This is because after defeating the Mongol soldiers, their strength was weakened, and they did not have long-term reserves, and they were still those soldiers, so their strength was extremely unstable.

Take a look at Mingyue's "Those Things in the Ming Dynasty".

Was it that the Ming Dynasty did not want to unify Mongolia? Definitely not. The Ming Dynasty was born from the hands of the Mongols, and the Ming Dynasty always wanted to capture the stronghold of the Mongols, so as to seize complete legitimacy, and there was a reason not to unify Mongolia.

But the problem is that although the Mongols withdrew from the Central Plains, their strength was still very strong, and the Ming Dynasty did not have a unified force. Since the founding of the Ming Dynasty, it has repeatedly attacked Mongolia, and Ming Chengzu has also personally conquered Mongolia five times, but he has not occupied Mongolia itself, let alone unified Mongolia. Later, Ming Yingzong also carried out a personal expedition, and as a result, he went to the "North Hunt".

Later, although it was released back by Mongolia, the Ming Dynasty lost the strength to attack Mongolia and could only defend, even if its territory was not occupied by Mongolia, do you still want to unify Mongolia.

As a result, the Mongols failed to unify the Mongols, initially due to a lack of strength, and later to a lack of willfulness and powerlessness.

The Ming Dynasty was a predominantly Han state, and it was a southern regime with no foundation and no ability to unify the entire north.

The founders of the Qing Dynasty were the Jurchen ethnic minorities, so they understood the details and advantages of the minority Mongolians; The Ming Dynasty was a southern regime dominated by Han Chinese, and it did not understand ethnic minorities, so it could not do it.

The Manchus themselves are an ethnic minority, mainly in the northeast, and they know some details about Inner Mongolia well, so it is relatively easy to unify. The capital of the Ming Dynasty was in the south, and I didn't know much about all aspects of the north, so it was more difficult to fight.

Because of the large-scale marriage between the Manchu royal family and the Mongol tribes, and then everyone entered the customs together, and together they became the ruling class and enjoyed the wealth.

Because for them, the Ming Dynasty was the real nomad.
