In 220, Sun Quan ordered Lü Dai to replace Bu Zhi as the Inspector of Jiao Province. Bu Zhi then led over 10,000 volunteer troops from Jiao Province to Changsha Commandery (長沙郡; around present-day Changsha, Hunan). About a year later, Liu Bei, the emperor of the state of Shu Han, launched a military campaign to attack Sun Quan in retaliation against Sun Quan's seizing of his territories in Jing Province in late 219. This subsequently led to the Battle of Xiaoting/Yiling of 221–222. During this time, some local tribes in Wuling Commandery (武陵郡; around present-day Changde, Hunan) in southern Jing Province rebelled against Sun Quan's rule. Sun Quan ordered Bu Zhi to lead troops to Yiyang County (益陽縣; east of present-day Yiyang County, Hunan) to guard against attacks from the rebels.
