Why did Zhu Yuanzhang, the only hero, let go and become a joke at that time?

Xu Da, the only hero of Zhu Yuanzhang, finally became the laughingstock of the world because of his poor fortune. Zhu Yuanzhang was born a beggar. At that time, there was a corrupt official who bullied the city and did all kinds of evil. And Zhu Yuanzhang suffered greatly, so Zhu Yuanzhang hated corrupt officials very much. ?

Shortly after the founding of People's Republic of China (PRC), Zhu Yuanzhang carried out a series of reforms aimed at punishing corruption. At that time, some ministers, who thought they were founding heroes, openly took bribes under Zhu Yuanzhang's nose and committed crimes against the wind. Zhu Yuanzhang flew into a rage when he found out. Obviously, these heroes didn't take themselves seriously because of their high achievements. Of course Zhu Yuanzhang can't stand it. Immediately ordered to investigate and deal with these corrupt people, from property to jail, and even to the whole family. In this investigation, tens of thousands of officials were killed in the aerial printing case. A large number of corrupt officials and heroes were also executed, because it was a collusion between central and local officials, which can be said to be huge in scale, and Guo Huan, assistant minister of the Ministry of Industry, abused the official seal and was finally copied. ?

Other heroes of the imperial court also relied on their great achievements and then constantly challenged Zhu Yuanzhang's bottom line. In the end, most of them were killed by Zhu Yuanzhang, and some of them were demoted and sent. There are very few heroes who can enjoy their old age. Xu Da, who ranks first in meritorious service, is such a survivor. Xu Da is not as arrogant as other heroes. He is very strict, so to speak, he is watertight. Moreover, he is smooth, so he is very popular with Zhu Yuanzhang. ?

After Hu was killed, Xu Da has been helping Zhu Yuanzhang deal with trivial matters in the DPRK. Later, Zhu Yuanzhang was ill in bed because of carbuncle on his back. Upon hearing this, he ordered steamed geese to be sent to help Xu Da make up for it. But I didn't expect to eat Zhu Yuanzhang's steamed goose Instead of getting better, Xu Da's condition got worse and worse, and he died soon. At that time, the world thought that Zhu Yuanzhang's steamed goose was poisonous, but it was not. Zhu Yuanzhang had no reason to get rid of such a loyal Xu Da. Moreover, after the founding of the People's Republic of China, Zhu Yuanzhang had many opportunities to grant him the death penalty, so there is no need to wait until today. Later, Xu Da's family came down, and the world laughed at him for being loyal to his duties all his life, but he ended up like this.
