In Zhu Yuanzhang's tyrannical killing, why was Xu Da alone and the Xu family well treated?

After Zhu Yuanzhang established the Ming Dynasty, the founding monarch began to have doubts about heroes. Many heroes died under Zhu Yuanzhang's butcher's knife. Managed to survive under the suspicion of Zhu Yuanzhang, largely because of his deep feelings with Zhu Yuanzhang, but also because Xu Da is quiet and taciturn. Xu Da is a wise man. He knows Zhu Yuanzhang's character, so he can avoid it. Because of this, Zhu Yuanzhang admired him very much, and he also became his children's in-laws. His three daughters were all married to Zhu Yuanzhang's son, so he was well paid in the Ming Dynasty.

Xu Da was Zhu Yuanzhang's hometown since he was a child. If anyone knew Zhu Yuanzhang best at that time, it was Xu Da. Xu Da made numerous exploits in his life and saved Zhu Yuanzhang several times, so Zhu Yuanzhang was very grateful to Xu Da and appreciated him very much. Plus they have been together since childhood, so Zhu Yuanzhang always treats Xu Da a little more intimately than other heroes.

And Xu Da's character is relatively calm, he is calm and coherent, and he knows Zhu Yuanzhang's temper like the back of his hand. When he followed Zhu Yuanzhang, he was mostly silent and just worked hard, while Xu Da was very cautious and modest. He kept quiet about people and things, and Zhu Yuanzhang liked Xu Da's character very much. So Zhu Yuanzhang let his three sons marry Xu Da's daughter, which is why he took a fancy to Xu Da's simple family style. Therefore, the Xu Da family was very favored in the Ming Dynasty.

It is said that it is difficult to keep a job, but it is really difficult to manage your own property. Zhu Yuanzhang only needs to think a little about attacking the city to repair the world, but if he owns the world, he must think about the world. Xu Da was able to reassure Zhu Yuanzhang because he was humble, so his family was given preferential treatment in the Ming Dynasty.
