What the hell happened to Zhu Yunwen? Is there any record in history?

In July of the first year of Jianwen (1399), Zhu Di, the prince of Yan, set up an army in Beiping (now Beijing), wrote a letter to Jianwen Emperor, accusing Qitai and Huang Zicheng who advocated "cutting the vassal" as "treacherous officials", and quoted "Instructions to the ancestors of the Emperor Ming Dynasty" as saying that "if there is no official in the court, if there is evil in it, the prince will train his soldiers to stand by, and the emperor will secretly order the kings to lead the town to make peace. He said that he started to fight for "Jing Nan". In the name of "Qingjun side", he sent troops south. Historically, this war for the throne within the ruling class of the Ming Dynasty was called "the Battle of Jing Nan". History books refer to Zhu Di's army in the Battle of Jing Nan as "Northern Army" or "Yan Army". The imperial army was called "Southern Army" or "Julian Waghann".

according to the Ming history, Zhu di started his army with only 8 men, but after 2 days, it was "numerous to tens of thousands", and the maximum strength was only about 1, men. In the face of the absolutely dominant Jianwen imperial army (5,-6, people), Zhu Di knew that people were good at their duties and attacked at the right time, and finally "ruled the world with one corner". History says: "According to the land where the secluded swallow wins, it is weak by virtue of Jianwen, and it is inward-looking, and elections are everywhere. Knowing that people are good at their duties, they are both superficial and profound, and they are brave and brave, and they are the same as Gaozu. "

In June of the fourth year of Jianwen (142), Zhu Di's army arrived in the capital (now Nanjing). When they arrived at Jinchuan Gate, Gu Wang Yi, Li Jinglong and others opened the door and surrendered. The capital fell and the whereabouts of Jianwen Emperor were unknown. The princes advised Jin on the table. Zhu Di was the emperor and changed to Yongle. Zhu Di is Ming Chengzu.

As for the ending of Emperor Jianwen, there is a detailed record of "Jianwen Xunguo" in The Chronicle of the Ming Dynasty by Gu Yingtai, a Qing Dynasty man, but the credibility is not high. In the Ming History written by Zhang Tingyu, a Qing Dynasty, there are different opinions about the whereabouts of Emperor Jianwen, and all kinds of opinions are inclusive. In the fourth chapter of this discipline, it is said that after Yan Bing was trapped in the capital (Nanjing), "the fire broke out in the palace and the emperor did not know what to do. The prince sent the queen's body to the fire, and he refused to apply for burial on the eighth day. " "or the cloud emperor died from the tunnel." "Since then, between Yunnan, Guizhou, Pakistan and Shu, it is said that there are traces of the emperor's dealings as a monk."
