[4][5] Between 194 and 199, Sun Ce embarked on a series of conquests in the Jiangdong region and established his power base there.
Around the time, the warlord Cao Cao, who controlled the Han central government and the figurehead Han ruler, Emperor Xian, became wary of Sun Ce's growing influence in the south, so he sought to establish marital ties with Sun.
He fought in the Wu army at the Battle of Dongkou of 222–223 against Wei invading forces commanded by Cao Xiu.
In 270, Sun Hao sent an officer, He Ding (何定), to lead 5,000 troops to Xiakou for a hunting expedition.
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).
[11] 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.
