Records of the Three Kingdoms
Sun Xiu, courtesy name Zilie, was Sun Quan’s sixth son. During Sun Liang’s reign he was Prince of Langya and lived at Hulin and Danyang, keeping his distance from Sun Chen. In 258 Sun Chen deposed Sun Liang and brought Sun Xiu to the throne. Sun Xiu added to Sun Chen’s titles in public and, with Zhang Bu and Ding Feng, set a trap. At the year-end banquet they seized Sun Chen and executed him, then killed his clan.
In the Yong’an years Sun Xiu issued orders on clerks and schools. Wu did not launch a great foreign war. In 264 Shu fell while he was already gravely ill. He died soon after, at thirty, and was titled Emperor Jing. The ministers did not enthrone his son. They brought in Sun Hao, son of Sun He.
Romance of the Three Kingdoms
In the novel Sun Xiu carries the chapter in which Sun Chen dies: he waits, then turns at the banquet. Ding Feng and Zhang Bu move on his plan.
The six years of his reign pass quickly. After his deathbed charge, the ministers set his son aside and welcome Sun Hao. The book treats that choice as the start of Wu’s last decline.
