Zhu Zhanxiu, the king of Chuan, had just succeeded to supervise the country when the Tumu Fort army was completely destroyed and Yingzong was captured. The court forced him to move the capital, and Yu Qian shouted back. Zhu Zhanxiu allowed him to supervise the capital camp, transport grain to the prefecture, and adjust Nanjing's arsenal. He shouldered the pressure of Empress Dowager Sun and argued with the ministers, defended Beijing and forced Oara to retreat, and rewrote the script of the Ming Dynasty's fall.
