Sun Chen (231 – 18 January 259),[a] courtesy name Zitong, was a military general and regent of the state of Eastern Wu during the Three Kingdoms period of China.
Sun Chen struck back militarily, and his forces defeated Teng Yin and Lü Ju.
In the light of his defeat of Teng Yin and Lü Ju, Sun Chen began to become extremely arrogant.
He established a personal guard corps, consistent of young men and officers with age similar to his, stating that he intended to grow up with them.
A small Wu detachment, led by Wen Qin, himself a former Wei general who had defected to Wu, quickly arrived to assist him, but Sun Chen led the main forces and chose to camp a long distance away from Shouchun, where Zhuge Dan was being besieged by Sima Zhao, and did nothing.
With Sun Chen unable to do anything, Zhuge Dan's rebellion failed in 258, and Wen Qin's troops became captives of Wei.
[5] Sun Chen knew that the people and the young emperor were both angry at him, and chose not to return to Jianye, but instead sent his confidants to be in charge of the capital's defences.
He conspired with Zhang Bu and the senior general Ding Feng to kill Sun Chen during the Laba Festival.
