Son of Emperor Hui

In the reign of Zhenguan, King Li Shimin of Qin killed his brother and brother, which was the change of Xuanwumen; in the prosperous era of Yongle, during the battle of Jingnan, Emperor Chengzu of Ming Dynasty, the whereabouts of Emperor Jianwen were unknown; what about the reign of Wenjing? "The Emperor is here, why should he step in?" When the ten visitors stood in front of the end gate of Weiyang Palace holding halberds and shouted these words to the acting king Liu Heng who was riding the emperor's frame, they probably thought that the two emperors they had guarded for eight years would actually distort their bloodline and surnames in Ban Gu's writings! Li Jiancheng pursued the title of King Xi and named him Prince Yin. Emperor Jianwen deeply sympathized with him and there were countless rumors—— No matter how brilliant his political achievements are, they should not cover up the truth of history. How can our Emperor Taizong Wen of the Han Dynasty be an exception?
