In 213, as soon as Cao Cao and his army left Liang Province, as Yang Fu foresaw, Ma Chao attacked the commanderies in Liang Province with support from Zhang Lu, a warlord in Hanzhong Commandery. Ma Chao soon besieged Ji County, the last stronghold in Liang Province which remained under Han control. Despite Yang Fu's valiant efforts to resist the enemy, Ji County still fell to Ma Chao, and Yang Fu was forced to submit to Ma Chao. Disgruntled by Ma Chao's cruelty and treachery (including his murder of Wei Kang, the Inspector of Liang Province), Yang Fu and other officials in Liang Province secretly hatched a plot to drive Ma Chao out of Liang Province. Yang Fu lied to Ma Chao that he wanted to see to the funeral arrangements for his recently deceased wife and gained permission to leave Ji County. He then used the opportunity to contact the other officials and prepare for their revolt against Ma Chao.
