After the change of the civil fort, Zhu Qiyu, the younger brother of Yingzong, succeeded to the throne, formerly known as Daizong, with the year number Jingtai. When the Wala army invaded Beijing, Yu Qian urged it to fight with Wala and defend the capital to the death, which won the support of Jingdi. After defending Beijing, Vacci was defeated and Emperor Zhu Qizhen was unconditionally released back to North Korea. After Yingzong came back, Daizong did not return the throne to him, but respected Yingzong as the emperor's father, and let him live in the Nangong, and sealed it tightly to prevent accidents.

In the eighth year of Jingtai (AD 1456), Daizong suddenly became seriously ill and bedridden, and the problem of "translocation" became a topic of private discussion among ministers. The marquis of Wu Qing and the eunuch in the palace advocated that the former prince should be enthroned. Xu Youzhen, the minister, thinks that Dai Zhong is seriously ill and the emperor's father is still alive, so it is better to take this opportunity to support the emperor's restoration. In this way, we will not only succeed, but also be promoted to rank and knight in the future. Shi Heng and Cao Jixiang listened to Xu Youzhen and thought it was feasible. They immediately split up and prepared for a coup.

In the first year of Tianshun (A.D. 1457), the 16th night of the first month. Shi Heng and Cao Jixiang, with 65,438+0,000 soldiers, rushed to the Nangong, broke the palace gate, forced their way in, took out Yingzong imprisoned inside and rushed directly to the Fengtian Hall. Cao Jixiang immediately sent his trusted eunuch to summon ministers, and asked courtiers to appear in front of the hall immediately, saying that they had something important to announce. As soon as the ministers arrived, bells and drums rang in the main hall, and I saw Yingzong, who had been imprisoned for a long time, sitting on the throne in the upper hall. Ministers returned to the Imperial Palace with the eunuch "Emperor Tai-huang" from Li Si. The voice of "a hundred officials from the civil and military forces appear before the temple" is endless, and they kneel on the ground one after another, giving a great gift to the successful restoration of Yingzong.

Once in power, Yingzong unceremoniously abolished Zhu Qiyu, and Daizong, as the king of Xi, moved it back to the Western Regions, and then banned it in Xiaonancheng (now Purdue Temple in Wang Hongbin). Yingzong also wrote many times, stating that his brother, who had been emperor for eight years, was "unfilial and unjust".

Only one month after leaving the throne, Zhu Qiyu died at the age of 30. Buried in Xishan (now Jingtai Mausoleum in Jinshankou) for the Prince. From then on, British Emperor Zhu Qizhen began his second reign for eight years. This event, known in history as "the change of seizing the door", also known as "the restoration of Nangong", was the second battle for the throne within the ruling group of the Ming Dynasty.
