As we all know, in Chinese history, the use of death-free iron coupons (that is, death-free gold medals) has a shelf life, and if it encounters a reputable emperor, its use may last for a long time until the dynasty; But if you encounter an emperor who turns his face and does not recognize people, the effectiveness of the iron coupon is debatable. For Zhu Yuanzhang, the founding emperor of the Ming Dynasty, he issued to the heroes not so much as a death-free iron coupon as a "one-way pass to hell", because about 90% of the founding heroes were killed, as the saying goes: "The lord wants the subject to die, and the subject has to die." "Don't talk about iron coupons, even gold coupons and diamond coupons can't save the lives of heroes, and Li Shanchang is one of the most typical representatives."
However, there are exceptions to everything, Zhu Yuanzhang also once bypassed the life of a descendant of the Qian clan, and the basis was only a "death-free iron coupon" left over from the Tang Zhaozong period. It turned out that in 1391, Zhu Yuanzhang was dealing with the corrupt officials of the Ming Dynasty at that time, and at most thousands of corrupt officials fell to the ground in one day, in this case, every official had to tremble and act carefully, afraid that he would have any connection with the corrupt officials.
One day, Zhu Yuanzhang personally tried a corruption case, and the prisoners on trial were descendants of Qian Wei during the Five Dynasties and Ten Kingdoms period. Just when Zhu Yuanzhang's interrogation was completed, the prisoner suddenly took out a death-free iron coupon from Tang Zhaozong more than 500 years ago, and wanted Zhu Yuanzhang to spare his life, so what is the origin of this death-free iron coupon?
It turned out that during the tang zhaozong period, the wuyue king Qian Wei was ordered to go to Jiangnan to quell the rebellion, and in just a few years, the local peace was restored, and Tang Zhaozong, in order to thank Qian Zhaozong, gave him a death-free iron coupon engraved with the words "Forgive his nine deaths, and his descendants die three times", and have been preserved by his descendants to this day. What makes people feel strange is that Zhu Yuanzhang actually let go of his descendants after seeing this death-free iron coupon, so what considerations did Zhu Yuanzhang approve of this death-free iron coupon and release people?
In fact, the reason why Zhu Yuanzhang approved of the death-free iron coupon for Qian's descendants was because he wanted to convey a message to the people of the world: I Zhu Yuanzhang is not a murderous demon, as long as you can be loyal to me like the ancestors of the Qian family, then your descendants can get the protection of the Ming Dynasty royal family.
