王守澄
As part of Emperor Wenzong's and Song's plans to eliminate the eunuchs' power, in 831, Song recommended Wang Fan () to be the mayor of Jingzhao Municipality (京兆, i.e., the Chang'an region) and secretly informed Wang Fan of Emperor Wenzong's plans. However, Wang Fan then leaked it, and Wang Shoucheng and Zheng became aware of it. In response, Zheng had the Shence Army officer Doulu Zhuo () falsely accuse Song and Emperor Wenzong's brother Li Cou the Prince of Zhang of plotting to overthrow Emperor Wenzong and replace him with Li Cou. When Wang Shoucheng then reported Doulu's accusations to Emperor Wenzong, Emperor Wenzong was shocked and believed it to be true, and immediately ordered investigations. Wang Shoucheng wanted to send Shence Army soldiers to immediately slaughter Song's household, but at the urging of the eunuch Ma Cunliang (), this immediate slaughter was not carried out. Rather, Emperor Wenzong ordered that the chancellors immediately be summoned. When the chancellors — Song, Lu Sui, Li Zongmin, and Niu Sengru — arrived at the palace gate, a eunuch announced, "Song Shenxi is not summoned!" Song realized that he was being accused of a crime, and, after knocking his writing board on his head, withdrew back to his household to await punishment. When he arrived at his mansion, his wife asked him, "You, Lord, are a chancellor, the pinnacle of what a subject can reach. Why do you wrong the Son of Heaven and rebel?" He responded, "My entire life I have received the emperor's grace, and I was promoted to be chancellor. I could not remove the wicked, and was instead accused by them. You, Lady, should know that I, Song Shenxi, am no rebel." They wept together.
