The battle of Jingnan was a battle for the throne within the ruling class that broke out shortly after the death of Zhu Yuanzhang, the founding emperor of the Ming Dynasty.

First of all, Mao gave the word.

Tiexuan was smart and knowledgeable when he was a child. When he was young, he went to imperial academy to study and learned more. Ming Taizu was a etiquette official at that time, and was later transferred to the Governor's Office to hear the case. He quickly solved the case, won the appreciation of Ming Taizu, and gave him a word "Shi Ding".

Second, fight against the Yan army.

In the thirty-first year of Hongwu (1398), Sun declared himself emperor when he died. In order to strengthen centralization, Zhu Yunwen implemented a vassal system. In the first year of Wen Jian (1399), Judy, the prince of Yan, was dissatisfied with the separatist regime. Zhu Yunwen sent Li Jinglong to crusade against Judy. At that time, Tie Xuan served as the political representative of Shandong, providing Li Jinglong with food and grass.

In the second year of Wen Jian (1400), Li Jinglong and Judy fought in Baigou River, and Li Jinglong fled in a fiasco, and all counties in Hebei took refuge in Judy. Tie Xuan heard that Li Jinglong was defeated and wept bitterly. He and Sheng Yong decided to defend Jinan and fight against the Yan army. Judy went south to pursue Li Jinglong, and Li Jinglong fled to Jinan after repeated battles and defeats. Yan army surrounded Jinan, and Tie Xuan and Sheng Yong defended Jinan. Judy attacked Jinan day and night and was defeated by Tie Xuan.

Third, it fell short.

Tie Xuan pretended to surrender, hoping Judy would go to town to surrender. Judy couldn't attack for a long time. When he saw Jinan surrender, he thought there was no ammunition and no food in the city, so he surrendered in the city. Tie Xuan arranged an ambush in the city, ready to wait for Judy to enter the city, close the door to catch the thief, and arrest him while he was unprepared. I didn't expect Judy to come late, so the ambush lost the gate ahead of time and Judy fled back to the camp.

Fourth, it is impregnable.

Judy was furious and captured Jinan. Tie Xuan sticks to Jinan, and the city is impregnable. Judy couldn't even get away after being surrounded in March. Judy was very depressed when she saw that she could not attack again and again, so she called for cannons to bombard Jinan city.

Tiexuan hung Ming Taizu's coffin on the wall. Judy saw it and had to give up the shelling. The commander-in-chief led 200,000 troops to attack Yan in the north. Judy was afraid of breaking the route for providing foodstuff, so she had to retreat.

Fifth, the iron skeleton is clanking.

Zhu Yunwen was very happy when he saw Tie Xuan beat Judy many times. He was appointed as the special envoy of Shandong, and was soon promoted to the position of Minister of War. Zhu Yunwen sent Sheng Yong to replace Li Jinglong as General Yan Ping, and ordered Tie Xuan to participate in military affairs. Soon, Sheng Yong led the army to defeat the Yan army in Dongchang, and Judy was defeated. Since then, he has never dared to go south via Shandong.

Zhu Yunwen ordered Wen Yang, the company commander of Liaodong, to lead the army south to meet Tie Xuan, ready to cut off Judy's posterior approach. Wen Yang marched into zhi gu, was defeated by the Yan army, and failed to join forces with Tie Xuan.

In the fourth year of Wen Jian (1402), Judy heard that Nanjing was empty and led the army south, pointing directly at Nanjing. Sheng Yong and Tie Xuan stopped Yan Jun, but were defeated and captured. Judy ascended the throne and persuaded Tie Xuan to surrender. He would rather die than surrender and called Judy a traitor. Judy was furious and put him to death.
