Wang Shoucheng
Both Li Xun (then named Li Zhongyan) and Zheng Zhu were associates of the powerful eunuch Wang Shoucheng initially, and it was Wang who introduced both to Emperor Wenzong. Nevertheless, as, over the years, Wenzong showed signs of resentment toward the eunuchs, Li Xun and Zheng, particularly because they were not suspected by the eunuchs due to their association with Wang, began plotting with Wenzong to destroy the powerful eunuchs. As of summer 835, Li Xun and Zheng had persuaded Wenzong with a detailed plan that included a three-phase plan for him to pacify the empire — first destroying the eunuchs, then recovering the lands lost to the Tibetan Empire, and then destroying the warlords north of the Yellow River.
