Zhu Yuanzhang issued a large number of iron coupons to avoid death. When heroes were killed by him, why didn't he use them?

Because Zhu Yuanzhang executed many founding heroes for treason, and it is inevitable to avoid death, so the minister can only be executed by Zhu Yuanzhang.

Most of the founding heroes were actually killed unjustly. They were labeled traitors by Zhu Yuanzhang for no reason, and they didn't have the opportunity to use the gold medal of death. Zhu Yuanzhang was able to become emperor, and the founding heroes contributed a lot. They created Zhu Yuanzhang. Zhu Yuanzhang knew that the first thing to do was to stabilize these heroes, so when the People's Republic of China was founded, he rewarded their contributions and gave them a gold medal to save them from death. However, the use of this kind of death-free gold medal is limited, and treason can not be pardoned by the death-free gold medal, which makes Zhu Yuanzhang exploit a big loophole.

Zhu Yuanzhang used the famous Hu case and aquamarine case to classify a large number of founding heroes into the ranks of rebellion, so that they could not use the gold medal to avoid death. Because the protagonist committed the great crime of rebellion, Zhu Yuanzhang's execution of them would not violate morality. Some people get away with it. They want to survive and ask to go back to their hometown to save their lives.

Later, Zhu Biao died, and Zhu Yuanzhang's health became worse and worse. In order to clear the way for his grandson Zhu Yunwen, he directly ordered the killing of some heroes. No one dares to disobey the emperor's orders. Heroes die, at least their descendants can still live, and some even choose to commit suicide. Zhu Yuanzhang's life is not long. It really doesn't matter whether he is famous or not. He just wants his country to continue. Zhu Yuanzhang killed so many heroes that he thought he could have a stable future. Surprisingly, his son Judy finally ousted Zhu Yunwen from the throne. Zhu Yuanzhang's thousands of calculations did not count Judy's persistence in the throne.
