Why did Xu Da deliberately let Yuan Shundi go twice? What is his real intention?

Because trying to let Yuan Shundi go was inspired by Zhu Yuanzhang, and his real intention was to safeguard Zhu Yuanzhang's interests. Although the Yuan Dynasty has perished, Yuan Shundi is still a symbol of orthodoxy. Zhu Yuanzhang could not kill him casually, and repeatedly instructed Xu Da to release water.

Xu Da released Yuan Shundi and Xu Da twice and was ordered to lead the army back to Yuan. However, he was stationed in a place dozens of kilometers away from the Yuan Dynasty to rest. After Yuan Shundi fled, Xu Dacai slowly ordered the army to advance and occupied the Yuan Dynasty. Yuan Shundi fled to Shangdu with a group of nobles, and Xu Da caught up with a great army and surrounded Shangdu, but he did the same thing again and let Yuan Shundi go again. Chang Yuchun was furious and participated in a book by Xu Da. Zhu Yuanzhang smiled cunningly. Yes, it was all his idea.

Zhu Yuanzhang didn't want to cause anger. Although the Yuan Dynasty wanted to destroy the country, no matter how unpopular Yuan Shundi was, there would still be people who supported him because he was an emperor. If Xu Da retakes Yuan Shundi and Zhu Yuanzhang kills Yuan Shundi, it may anger those who support Yuan Shundi, and then Zhu Yuanzhang will not be able to end it. Moreover, Zhu Yuanzhang has always been grateful to the Yuan Dynasty. He thought that their food and clothing were given by the Yuan Dynasty, and there was no need to destroy Yuan Shundi.

After all, Yuan Shundi was the orthodox Zhu Yuanzhang of the uprising. If he succeeds, he is an emperor; If he fails, he will be a rebel and a traitor. His essence is not orthodox. The Yuan Dynasty ruled for nearly a hundred years, and everyone agreed that Yuan Shundi was the orthodox emperor. Zhu Yuanzhang's rebellion was all wet. If he kills Yuan Shundi again, the charge of anti-theft will really be shelved. However, if Yuan Shundi voluntarily gives up the orthodox throne and gives it to Zhu Yuanzhang, then Zhu Yuanzhang's accession to the throne is to conform to God's will and the general trend.

In any case, Zhu Yuanzhang didn't want to catch Yuan Shundi, because this man can't be killed, and catching him will only increase the trouble. The best way for Zhu Yuanzhang to think of this hot potato is to throw him out.
