Wang Shoucheng
In spring 820, Emperor Xianzong died suddenly — and historians generally believed that it was the eunuch Chen Hongzhi (陳弘志) who murdered him. The eunuchs Liang Shouqian (梁守謙), Ma Jintan (馬進潭), Liu Chengjie (劉承偕), Wei Yuansu (韋元素), and Wang Shoucheng, had Tutu and Li Yun killed, and they supported Li Heng to succeed to the throne (as Emperor Muzong). During the reign of Emperor Muzong's son Emperor Jingzong, the eunuch Ma Cunliang (馬存亮) submitted a petition listing the accomplishments of Tutu, and Emperor Jingzong allowed Tutu's adopted son Tutu Shiye (吐突士曄) to have Tutu Chengcui reburied properly. During the subsequent reign of another of son of Emperor Xianzong's, Emperor Xuānzong, Tutu Shiye was further promoted to be commander of the Right Shence Army (右神策軍).
