After Zhu Yunjiao ascended the throne, due to the over-eagerness to implement the policy of cutting the domain, it caused Zhu Di, the King of Yan, to raise an army. Zhu Di marched from north to south, under the banner of the Battle of Jingnan, preparing to occupy Dabao himself. Zhu Di followed his father Zhu Yuanzhang in many battles to establish the country, so he had a lot of experience. And Qi Tai, Huang Zicheng and others appointed by Zhu Yuanzhang were mostly people who talked on paper. So Zhu Di won many victories.
However, when attacking Jinan City, Zhu Di encountered an opponent! He is the iron string. When Zhu Di raised an army, he was promoted to the rank of Shangshu of the Bingbu And held a high position of authority. Not only was he reluctant to surrender, but he also integrated his defeated troops into a deadly battle in the city of Jinan. Jinan is an important city connecting the north and the south, and if it cannot be captured, it will definitely cause an important blow to Zhu Di.
At that time, due to the defeat of Li Jinglong's army, the entire inner city of Jinan was surrounded by the Yan King's regiment, and Tie Xuan, who was transporting grain and grass, heard about it and hurriedly led his army to help. At that time, Zhu Di hoped that Tiexian would surrender, but Tiexian also shot a letter, hoping that Zhu Di could assist Emperor Jianwen in the same way that the Duke of Zhou assisted King Wu.
At that time, Tie Xian also used a trick to lure Zhu Di into the city, preparing to smash Zhu Di to death with a boulder under the city gate. However, the plan failed, and Zhu Di, who was embarrassed and angry, mobilized heavy artillery to prepare to shell the city of Jinan. However, the iron string not only hung zhu Yuanzhang's portrait at the city gate, but also distributed the written Zhu Yuanzhang ranking in various directions on the city wall. Zhu Di threw a rat taboo, did not dare to disrespect his father's rank, and could only angrily scold below, and had no choice but to retreat. Later, Zhu Di did not capture Jinan, but after bypassing Jinan, he took Nanjing and finally ascended to the throne.
After becoming emperor, Zhu Di did not forget the shame of the past and punished those who dared to rebel against him. Zhu Di mobilized heavy troops to finally capture Jinan, tiexian was arrested, and later executed by Ling Chi. Tie Xian's family did not escape the disaster, his parents were assigned, the eldest son was filled with the army, the second son was made an official slave, and his wife and daughter were charged into the official brothel. At that time, many female relatives of Jianwen courtiers were in this situation, such as Qi Tai, Huang Zicheng and others. Iron String's wife was bullied, while his daughter escaped death because she was too young. Later, Zhu Di eventually pardoned his two daughters and married them to the readers.
One more thing about iron string integrity. Zhu Di cut off the ears and nose of the iron string, cooked it and forced it into the mouth of the iron string, and then asked him what tasted? Iron Strings was not afraid, Iron Bone Zhengzheng, and replied that there was something bad about the flesh of the loyalists? In the current Jinan, there are also many city god temples commemorating iron strings.
Although Zhu Di was annoyed with the iron string, he also admired him. Although he cursed the iron string many times, he still praised it in front of the courtiers. It can be seen that the ass decides the head, and Zhu Di, when he was anti-king, did not want to meet people who fiercely rebelled against him; and after becoming emperor, he hoped that all the courtiers under his rule were like iron strings.
