In 835, the officials Wang Fan (王璠) and Li Han (李漢) accused Li Deyu of having associated with Emperor Wenzong's brother Li Cou the Prince of Zhang, hoping to support Li Cou as emperor to replace Emperor Wenzong. Emperor Wenzong, in anger, summoned a tribunal of chancellors to judge Li Deyu. Lu Sui spoke in defense of Li Deyu, and he was relieved of his duties and exiled to Yuan Prefecture (袁州, in modern Yichun, Jiangxi) to serve as its secretary general. Lu himself suffered the consequences of being sent out to Zhenhai to serve as its military governor and, contrary to the regular official movements at the time, he was not allowed to meet with Emperor Wenzong before his departure. Soon thereafter, Zheng Zhu's associate Jia Su was made chancellor.
