Bu Zhi
Bu Zhi (died June or July 247), courtesy name Zishan, was an official and military general of the state of Eastern Wu during the Three Kingdoms period of China. Originally a scholar of humble background, he became a subordinate of the warlord Sun Quan in the late Eastern Han dynasty and gradually rose through the ranks. Between 210 and 220, he served as the governor of the remote and restive Jiao Province in southern China. During the Battle of Xiaoting/Yiling of 221–222, he quelled local uprisings in Sun Quan's territories in southern Jing Province and maintained peace in the area. After Sun Quan became emperor in 229, Bu Zhi oversaw the Wu armed forces guarding the Wu–Shu border at Xiling (present-day Yichang, Hubei) for about 20 years. During this time, he also gave advice to Sun Quan's first heir apparent, Sun Deng, and spoke up for officials affected by Lü Yi's abuses of power. In 246, he became the fourth Imperial Chancellor of Wu, but died in office in the following year.
