Meng Huo
After failing to capture Yongchang Commandery from Lü Kai and Wang Kang, Yong Kai turned to the Nanman tribes for help but they were unwilling to listen to him. Yong Kai then sought help from Meng Huo, a local leader with much influence and popularity among the Nanman. Meng Huo lied to the Nanman that Shu's government had made unreasonable demands from them and successfully incited them to rebel against Shu's rule.
