After Zhu Yuanzhang established the Ming Dynasty, Yuan Shundi ran to Zhongdu first, but Zhu Yuanzhang thought it was not far enough, so he rushed to Shangdu directly. Compared with Beijing, the natural conditions of Shangdu are extremely harsh, and broken walls and Yuan Shundi are everywhere, which is quite bleak.

However, according to the "Ming History", "the population is not less than one million, the equipment is still excellent, and there are famous players such as Kuankuo Timur". That is to say, after the demise of the Yuan Dynasty, there were millions of soldiers under Yuan Shundi, which is not a small number. Such a powerful military force can completely overthrow a regime. So, why didn't Yuan Shundi send millions of soldiers south to fight the Ming Dynasty?

In fact, it's not that Yuan Shundi doesn't want to do this, but it's impossible! Although Yuan Shundi arrived in Shangdu, the imperial army was not completely concentrated in Shangdu. After all, the Yuan Dynasty was built on horseback. Now, after the demise of the Yuan Dynasty, these troops will naturally return to the grasslands, become nomadic people, and form one tribe after another. Because of this, Yuan Shundi simply ordered these tribal leaders not to move, and the so-called kidnapping of millions of soldiers was just Yuan Shundi's wishful thinking. Yuan Shundi was neither Kublai Khan nor Genghis Khan. He doesn't have the prestige of these two people at all, and the natural tribal leaders will not surrender to him again.

Of course, Yuan Shundi was able to command the army when he was in Beijing, mainly because he still had a group of officials to run the country, but once the Yuan Dynasty perished, these officials naturally changed their positions. After Yuan Shundi came to Shangdu, although he had a lot of money, these civil servants were not "repeat customers". Without the connection of the "civil service group", the so-called million soldiers are just a decoration, empty in appearance, but they can't play a role.

Therefore, although there were millions of soldiers in the Yuan Dynasty, they could not shake the Ming Dynasty anyway.
