Bu Zhi
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.
