王守澄
After Emperor Wenzong's enthronement, Wang Shoucheng was given the honorific title of "Piaoqi Dajiangjun" (驃騎大將軍) and made the commander of the Right Shence Army (右神策軍). As time went by, Emperor Wenzong came to be apprehensive that those he believed to be involved in Emperors Xianzong's and Jingzong's death were still in the palace, and, in particular, he became displeased at Wang's hold on politics and open receptions of bribery. He began to discuss a way to counteract Wang with the imperial scholar Song Shenxi, and in 830 made Song chancellor. After Song involved Wang Fan (王繙) the mayor of Jingzhao Municipality (京兆, i.e., the Chang'an region) in 831, however, Wang Fan leaked the plan, and Wang Shoucheng and Zheng Zhu came to know about the plan. Zheng reacted by ordering the Shence Army officer Doulu Zhu (豆盧著) to falsely accuse Song of plotting treason to put Emperor Wenzong's younger brother Li Cou the Prince of Zhang on the throne. When Wang Shoucheng relayed the accusation to Emperor Wenzong, Emperor Wenzong believed it and was angry. Wang Shoucheng initially wanted to take this opportunity to massacre Song's household, but was stopped by another powerful eunuch, Ma Cunliang (馬存亮). However, during the subsequent investigations by Shence Army officers, after an attendant official to the imperial princes, Yan Jingze (晏敬則), and Song's associate Wang Shiwen (王師文) were tortured and confessed to serving as conduits for messages between Song and Li Cou, Song was found to be guilty and was set to be executed. The advisorial officials Cui Xuanliang (崔玄亮), Li Guyan, Wang Zhi (王質), Lu Jun (盧均), Shu Yuanbao (舒元褒), Jiang Xi (蔣係), Pei Xiu (裴休), and Wei Wen (韋溫) urged caution, however, believed there were substantial questions in the matter and urged a reinvestigation by imperial government officials. The chancellor Niu Sengru also took the same view. Zheng, fearing that a reinvestigation would lead to discovery of the truth, suggested to Wang Shoucheng that he recommend to Emperor Wenzong that neither Song nor Li Cou be executed. Li Cou was thus demoted to the title of Duke of Chao County (巢縣, in modern Chaohu, Anhui) while Song was demoted to be the military advisor to the prefect of Kai Prefecture (開州, in modern Chongqing).
