《三国志·蜀书·庞统法正传》
冀州牧刘璋跟刘备在涪县会面，庞统建言说： 趁着这一次会面，可以抓获刘璋，这样将军不需要兴师动众，也能占据益州了。 
益州牧刘璋与先主会涪，统进策曰： 今因此会，便可执之，则将军无用兵之劳而坐定一州也。 
Liu Zhang, the governor of Jizhou, met Liu Bei at Fuxian County. Pang Tong advised Liu Bei, "Take advantage of this meeting to capture Liu Zhang. In this way, our army will not need to mobilize troops and can still occupy Yizhou."
