Chen Qun
In the days when Liu Bei was nominally the Inspector of Yu Province (where Yingchuan Commandery was located), Chen Qun became a subordinate of Liu Bei. He tried to dissuade Liu Bei from succeeding Tao Qian as the Governor of Xu Province after Tao died in 194 because he believed that whoever controlled Xu Province would be under threat from rival warlords: Yuan Shu to the south and Lü Bu to the east. Liu Bei ignored his advice and assumed office as the Governor of Xu Province, but he soon lost the province to Lü Bu.
