Sun Kai 孫闓

Sun Chen, courtesy name Zitong, shared a grandfather with Sun Jun. When Sun Jun died, Sun Chen, as Palace Attendant and General of the Martial Guard, took command of all the forces inside and outside the capital and ran the government of the court; he was later promoted to General-in-Chief, given the Staff of Authority and enfeoffed as Marquis of Yongning.

When Sun Liang first took personal charge of government and questioned him more and more, Sun Chen became very afraid. Returning to Jianye, he pleaded illness and did not attend court, built a residence south of the Zhuque Bridge, placed his younger brother Sun Ju, General Who Awes the Distant, in the Canglong Gate on guard duty, and stationed his younger brothers Sun En, General of the Martial Guard, Sun Gan, Lieutenant General, and Sun Kai, Colonel of the Changshui, separately in the various camps, seeking to dominate the court and secure his own position. Records, Wu 19 §87

Sun Chen deposed Sun Liang and received and enthroned Sun Xiu, Prince of Langya. Once on the throne, Sun Xiu issued an edict making Sun Chen Chancellor and Governor of Jing Province with five counties as his fief. Sun En became Imperial Counsellor and General of the Guards and Sun Ju General of the Right, both county marquises; Sun Gan became a general with a miscellaneous title and a village marquis, and Sun Kai too was enfeoffed as a village marquis. Chen Shou wrote that five men of Sun Chen's one family became lords and all commanded the palace troops, so that their power overshadowed the sovereign, something never before seen among the ministers of the Wu court.

When Sun Chen spoke resentfully to the General of the Left Zhang Bu, Zhang Bu reported it to Sun Xiu, and later the general Wei Miao and the soldier Shi Shuo also reported that Sun Chen was planning to rebel. When Sun Xiu asked Zhang Bu in secret, Zhang Bu plotted with Ding Feng to kill Sun Chen at a banquet. At the La festival banquet on the wuchen day of the 12th month of the 1st year of Yong'an (258; early 259 CE), Ding Feng and Zhang Bu signaled to the attendants to bind Sun Chen, and Sun Xiu beheaded him. Holding up Sun Chen's head, they proclaimed that all who had plotted with him were pardoned, and five thousand men laid down their arms. Records, Wu 19 §97–101

Sun Kai boarded a boat intending to go north and surrender, but he was pursued and killed. Sun Chen's three sets of kin were then exterminated, and because Sun Jun had killed Sun Luyu and others, Sun Jun's coffin was dug up, his seal and ribbon taken away, and the coffin hacked down and reburied. Records, Wu 19 §101

These three passages are the only places in Chen Shou's main text where Sun Kai's name appears, and his courtesy name, age and other deeds are not recorded. The assessment at the end of Records of Wu 19 called Sun Jun and Sun Chen vicious petty men brimming with arrogance, not worth discussing at all, and did not assess Sun Kai separately.
