Just 27 days into the new emperor's reign, Huo and the other officials took action. They summoned a meeting of high level officials and announced the plan to depose the emperor, forcing those other officials to go along with the plan or be killed. In a group, they went to Empress Dowager Shangguan's palace to report to her about Prince He's offences and their plan. She agreed with their plan, and ordered that Prince He's Changyi subordinates be immediately barred from the palace. These subordinates (some 200 individuals) were then arrested by Zhang. She then summoned Prince He, who did not know what was going to happen. He only knew something was wrong when he saw Empress Dowager Shangguan seated on her throne and wearing a formal dress made of jewels, and the officials lined up next to her.
