[3][4] In 196, after Sun Ce occupied Kuaiji during his conquests in the Jiangdong region, Dong Xi welcomed him at Gaoqian Village (高遷亭).
At the time, the bandits Huang Longluo (黃龍羅) and Zhou Bo (周勃) had gathered thousands of followers in Shanyin (山陰; in present-day Shaoxing, Zhejiang).
He also joined Sun Ce in the campaigns against Liu Xun at Xunyang (尋陽) and Huang Zu at Jiangxia Commandery (江夏郡; around present-day Xinzhou District, Wuhan, Hubei).
[6] Once, Peng Hu (彭虎) from Poyang (鄱陽) rallied thousands of followers and started a rebellion against Sun Quan.
Dong Xi, along with Ling Tong, Bu Zhi and Jiang Qin, led separate forces to attack the rebels.
In addition to all these defensive measures, Huang Zu also stationed more than 1,000 crossbowmen at Miankou, who rained arrows upon Sun Quan's forces when the latter attempted to push further.
The following day, Sun Quan held a banquet to celebrate the victory, during which he toasted to Dong Xi, "The purpose of today's feast is to honour the person who cut the rope!
Dong Xi's subordinates evacuated the warship and boarded the smaller boats (走舸; zouges) and pleaded for him to join them.
