Records of the Three Kingdoms
Sun Liang, courtesy name Ziming, was Sun Quan’s youngest son, by Empress Pan. When Sun Quan died in 252, Sun Liang became emperor at about ten. Zhuge Ke, as senior general and tutor, ran the government. After the victory at Dongxing, Zhuge Ke levied the people for another attack on Hefei and was badly beaten. Sun Jun killed him at a banquet. From then on Sun Jun, and after him Sun Chen, held Sun Liang’s court.
As Sun Liang grew he and Sun Chen distrusted each other. In 258 Sun Chen deposed him, made him Prince of Kuaiji, and welcomed Sun Xiu, Sun Quan’s sixth son. In 260 the court said the former emperor was plotting. He died on the road at eighteen. The accounts do not cleanly separate suicide from murder. He and Lü Meng share the courtesy name Ziming. They are not the same man.
Romance of the Three Kingdoms
The novel’s Sun Liang is a clever boy without power. Zhuge Ke’s dominance, the disaster at Hefei, and the banquet murder each have chapters. The deposition and Sun Xiu’s accession become a palace coup, with Ding Feng inside it.
Sun Liang’s death is not a climax. The Wu story moves on to Sun Xiu and Sun Hao.
