Zhang Song
Around 211, Zhang Song, an adviser to Liu Zhang, suggested to his lord to invite the warlord Liu Bei from Jing Province (covering present-day Hubei and Hunan) to assist them in countering their rival, Zhang Lu, in Hanzhong Commandery. Huang Quan strongly opposed Zhang Song's idea because he felt that Liu Bei was an ambitious person and might use the opportunity to seize control of Yi Province. However, Liu Zhang refused to listen to Huang Quan and he heeded Zhang Song's suggestion. Huang Quan was appointed as the Chief of Guanghan County (廣漢縣; south of present-day Shehong County, Sichuan).
