After entering politics, Sun Sheng served under Tao Kan, Yu Liang, and Huan Wen, accompanying the latter into Sichuan. On campaign, Huan Wen had taken his infantry to attack, and Sun Sheng was in charge of the weak, the elderly, and the baggage train, when they were suddenly set upon by thousands of bandits. The rearguard managed to rise to the occasion and drive them away. Huan Wen appointed Sun Sheng Marquis of Anhuai, in present-day Pingnan County, Guangxi, and he was attached to Huan Wen's household as a travelling secretary.
