Erzhu Zhao
In spring 531, Gao Huan was posturing to attack his distant relative Gao Gan (高乾), who had declared a rebellion at Xindu (信都, in modern Hengshui, Hebei), against the Erzhus. However, Gao Gan and Li Yuanzhong (李元忠) were able to persuade him that the Erzhus, because of their corruption, were hated by the people, and he could overthrow them. Gao Huan thereafter stirred his troops by forging orders from Erzhu Zhao that indicated that Erzhu Zhao was about to turn them into servants for his own troops. Gao Huan's troops believed the forged orders, and when he declared a rebellion in summer 531, they supported him.
