Late in 835, a plot by Emperor Wenzong, Zheng, and Li Xun to slaughter the powerful eunuchs (later known as the Ganlu Incident) failed, leading to the eunuchs' slaughtering of the imperial officials, including Zheng, Li Xun (who had been made a chancellor by that point), and Li Xun's fellow chancellors Wang Ya, Jia Su, and Shu Yuanyu. After the failure of the plot, in spring 836, Li Deyu was slightly promoted, to be the prefect of Chu Prefecture (滁洲, in modern Chuzhou, Anhui), and it was said that those officials previously exiled or demoted on account of being Li Zongmin's or Li Deyu's associates were beginning to be promoted as well. Soon thereafter, Li Deyu himself was again made the governor of Zhexi.
