Sun Xiu
Sun Tai's son, Sun Xiu (孫秀), served as General of the Vanguard (前將軍) and Area Commander of Xiakou (夏口督) during the reign of the fourth and last Wu emperor, Sun Hao (a grandson of Sun Quan). Sun Hao considered Sun Xiu a threat because Sun Xiu was a member of the imperial clan and wielded military power. In 270, Sun Hao sent an officer, He Ding (何定), to lead 5,000 troops to Xiakou for a hunting expedition. Sun Xiu suspected that Sun Hao had sent He Ding to Xiakou to kill him, so he brought along his family and bodyguards, numbering a few hundred people in total, and defected to Wu's rival state, the Jin dynasty. The Jin emperor Sima Yan received Sun Xiu warmly and appointed him as General of Agile Cavalry (驃騎將軍) and enfeoffed him as the Duke of Kuaiji (會稽公). Sun Hao was furious with Sun Xiu's betrayal so he banished him from the Sun clan and announced that Sun Xiu had changed his family name to "Li" (厲). In 280, Sun Hao surrendered to invading forces from Jin, bringing an end to the Wu regime. Many Jin officials went to congratulate Sima Yan, but Sun Xiu claimed that he was ill and remained at home. He faced his native land in the south and lamented the fall of Wu. The Jin imperial court praised him for that. After the fall of Wu, Sun Xiu was demoted from General of Agile Cavalry to General Who Calms Waves (伏波將軍) but was still allowed to have his own administrative office. He died sometime in the Yongning era (301–303) of the reign of Emperor Hui (Sima Yan's son and successor). Sun Xiu's son, Sun Jian (孫儉), continued serving in the Jin government as an Official Who Concurrently Serves in the Palace (給事中).
