Zhao Zhongyuan, who commanded 300,000 frontier troops, was jealous of the emperor and forced him to commit suicide. He pretended to remove his armor and return to Beijing, but in fact he laid out a series of schemes, taking advantage of the border army's movements, the prince's momentum to stir up the court situation, and even the death of Prime Minister Cui Yan to escape. In the end, the prince ascended the throne in the name of "Qing Junzi", the emperor was sent to the frontier fortress under house arrest, and Zhao Zhongyuan was executed in the name of "treason", thus achieving the stability of the new dynasty.
