After the establishment of the Ming Dynasty, Zhu Yuanzhang, in order to prevent Jiangshan from being usurped by outsiders, divided his children and grandchildren into various places as kings of the domain. Among these clan kings, the Nine Kings of Shubian were the most powerful. Originally, Zhu Yuanzhang's designated successor was Crown Prince Zhu Biao. Zhu Biao was known for his prestige among the kings, and if he succeeded to the throne, the Nine Kings of Shubian could only obediently accept the task of Shubian, but Zhu Biao died young. After Zhu Biao's death, Zhu Yuanzhang was discouraged and made Zhu Yunjiao, the emperor's eldest grandson, his successor. After Zhu Yunjiao ascended the throne, he also felt the pressure brought by his uncles, so he decided to follow the advice of the chancellor and start cutting the domain.
At that time, Zhu Quan, the king of Ning, "brought 80,000 armor and 6,000 leather cars", and Zhu Di, the king of Yan, held the heavy power of "controlling the horses along the border". Zhu Yunjiao also knew that these two people were not easy to deal with, so he decided to pick a soft persimmon to pinch first. The first vassal of Zhu Yunjiao was Zhu Xi [sù] the King of Zhou, who was the brother of the same father and mother. Zhu Yunjiao was afraid that the two of them would join forces later, so he decided to break Zhu Di's arm first. Just as Zhu Xu's son also accused him of rebellion, Zhu Yunjiao sent Li Jinglong to escort Zhu Xu's entire family back to Nanjing and depose him as a Shuren. After leveling the Zhou King, Zhu Yunjiao successively aligned with the King, the Xiang King, and the DaiWang. After these people were also solved, Zhu Yunjiao finally began to act against Zhu Di, the King of Yan.
In December of the 31st year of Hongwu, in order to prevent the rebellion of Zhu Di, the King of Yan, Zhu Yunzhuo appointed Zhang Fu , a servant of the Ministry of Works, as the envoy of Beiping, and appointed Xie Gui and Zhang Xin as the commanders of the capital of Beiping. Later, he sent the governor Song Zhongtun to Kaiping and transferred the army to which King Yan originally belonged. Zhu Di was not as weak as other princes of the clan, and seeing that Zhu Yunjiao wanted to attack him, he immediately moved out zhu Yuanzhang's "Ancestral Training of the Emperor Ming", accusing Qi Tai and Huang Zicheng of being traitors, and playing the slogan of "Qing Jun's side, Jingguo is difficult". After all, Zhu Yunjiao was young, and in terms of military affairs, he was much worse than Zhu Di. In the end, Zhu Dijing was unable to succeed, and the soldiers came to the city of Nanjing.
After Zhu Di entered the city, he found that Zhu Yunjiao was mysteriously missing, and there was no one dead or dead. In order to hide his eyes, Zhu Di recognized one of the scorched corpses in the fire as Zhu Yunjiao and announced that Emperor Jianwen was dead. After he became emperor, he sent people to look for Zhu Yunjiao from both land and water. Zheng He went to the West seven times, and the main purpose was to find Emperor Jianwen. Overland, Zhu Di sent his close minister Hu Qi [yíng] to secretly find Emperor Jianwen in the name of looking for Zhang Sanfeng. In order to carry out this task, Hu Qian spent more than ten years, and even his mother died of illness and did not go back, which shows the arduousness of the task.
So after Zhu Di became emperor, how did he treat Zhu Yunjiao's family? According to historical records, Zhu Yunjiao's empress died in the palace fire at the Battle of Jingnan. The scorched corpse that Zhu Di found should be Empress Jianwen. Zhu Yunjiao's crown prince Zhu Wenkui also disappeared with Zhu Yunjiao after the Battle of Jingnan. Zhu Yunjiao's pulse was only a two-year-old son, Zhu Wengui. Zhu Di was well aware of the principle of "cutting the grass without removing the roots, and the spring wind blows and growing again", but he was afraid that killing a two-year-old child would affect his own name, so he ordered someone to imprison Zhu Wengui and named him "JianshuRen".
Zhu Wengui's detention is more than fifty years. Later, after Ming Yingzong successfully launched the "Change of The Gate", he felt the pain of being detained, so he had Zhu Wengui released. Zhu Wengui was fifty-seven years old when he came out, and because he had been locked up in a small house since he was a child, he did not know men and women, nor did he distinguish between cows and horses. Emperor Ming Yingzong also wanted him to spread his branches and spread the leaves and pass on the lineage, and specially gave him more than ten maids, but Zhu Wengui died not long after because he could not adapt to the outside environment.
