On August 1627, 1 1 day, Xizong was critically ill and had no children, so his younger brother Zhu Youjian acceded to the throne. On August 22, Zong died, and then a decree was issued to send someone to welcome him into the palace. At noon, Zhu Youjian was welcomed into the Wenhua Hall, and civil and military officials visited him and advised him to go in. Zhu Youjian repeatedly conceded that it was not until sunset in the afternoon that Zhu Youjian agreed to accede to the throne.

At this point, the cabinet put forward four year numbers for its choice. These four titles are Gansheng, Xingfu, Xianjia and Chongzhen. Zhu Youjian carefully analyzed these four titles: "To be holy, to be heaven, the word holy really makes me unbearable;" Fuxing and ZTE are both very good, but as far as I am concerned, they are also incompetent. Xian Jia, there is a "ge" on the right side of the word "Xian Jia". At present, the national strength is weak, and the people are anxious to make a living, so Xianjia is not desirable; I think we should use Chongzhen! "

After the year number was decided, Zhu Youjian got up early at 5 o'clock the next day. He first came to his brother's grave to pay tribute to him. Then drive to Jianji Hall, put on the cassock, and offer sacrifices to heaven, earth, temple and country. Then he went to the Taiji Hall to worship heaven, and paid homage to his grandfather, some concubines whose father was still alive, and the emperor's wife, Zhang Taihou. Until noon, Zhu Youjian came to the palace, formally held the ceremony of accession to the throne, acceded to the throne as emperor. This is the Emperor Chongzhen in history.
