《资治通鉴·魏纪·魏纪八》
以前汉高祖幸运地占据了三秦之地，为什么他不闭关守住险要以自享娱乐，却偏要发动全部兵力去攻打西楚项羽，以致于身受创伤，甲胄里生满了虱子，将士们饱受艰难困苦，难道他甘心在刀剑里生活而忘记安宁了吗？
昔汉祖幸已自有三秦之地，何不闭关守险以自娱乐，空出攻楚，身被创痍，介胄生虮虱，将士厌困苦，岂甘锋刃而忘安宁哉？
In the past, Han Gaozu was fortunate to occupy the three Qin regions. Why didn’t he close the pass and guard the danger to enjoy himself, but mobilized all his troops to attack Xiang Yu of Western Chu, resulting in injuries, lice in his armor, and hardship for the soldiers? Did he willingly live in swords and swords and forget peace?
