(), granted him acting imperial authority, and enfeoffed him as a Marquis of a Chief District (). Suppressing Shi Hui's rebellion When Shi Xie, the Administrator of Jiaozhi Commandery, died in 226, Sun Quan commissioned Shi Xie's third son, Shi Hui (), as a general and appointed him as the Administrator of Jiuzhen Commandery (九真郡; around present-day Thanh Hóa, Vietnam). He also appointed Chen Shi () as the new Administrator of Jiaozhi Commandery to succeed Shi Xie. Around the time, Sun Quan wanted to split Jiao Province and create another province, Guang Province (): Jiaozhi, Jiuzhen () and Rinan () commanderies would remain part of Jiao Province; Cangwu (), Nanhai (), Yulin () and Hepu () commanderies would form the new Guang Province.

He had no choice but to lead his brothers out of the city and surrender to Lü Dai. Lü Dai later
