Liu Zhang
As time passed, Pang Xi became increasingly arrogant because he believed that Liu Zhang owed him a huge favour for saving his brothers' families in Chang'an and also because he thought that Liu Zhang deeply trusted him. It turned out that Liu Zhang gradually distrusted Pang Xi and began to alienate him. Around 211, when Liu Zhang's adviser Zhang Song urged his lord to invite another warlord Liu Bei into Yi Province to counter the threat posed by Zhang Lu, he warned Liu Zhang that Pang Xi might secretly harbour the intention of overthrowing him.
