Sun Hao
Sun Hao turned out to be a cruel and superstitious tyrant. His subjects were hesitant in attempting to persuade him to mend his ways, but due to Teng Mu's honoured status, they often asked Teng Mu to help them present their proposals to Sun Hao because the emperor might be offended if they gave him advice directly. Sun Hao eventually grew tired of Teng Mu's suggestions and Empress Teng fell out of her husband's favour as a consequence. In 266, Sun Hao suddenly ordered Teng Mu to move to Cangwu (蒼梧; in present-day Wuzhou, Guangxi) — effectively sending the latter into exile — even though he did not strip the latter of his titles. Teng Mu died of distress on the journey to Cangwu. Sun Hao considered deposing Empress Teng as well but his superstitious beliefs worked in the empress's favour — his sorcerers (whom he trusted) told him that replacing the empress would lead to disaster for him. Sun Hao's mother, Empress Dowager He, also intervened by protecting and speaking up for Empress Teng. Empress Teng lived with her mother-in-law and rarely saw Sun Hao again but retained her authority as the empress. At the same time, Sun Hao gave empress signets to many of his other concubines.
