《资治通鉴·魏纪·魏纪六》
如今兴势地形十分险要，蜀军已率先占据，如果进攻，敌人不应战，退却又被阻截，全军必然覆灭，你将承担什么责任？ 
今兴势至险，蜀已先据，若进不获战，退见邀绝，覆军必矣，将何以任其责！ 
Nowadays the terrain is extremely dangerous. The Shu army has already taken the initiative to occupy it. If we attack, the enemy will not fight, and if we retreat, we will be blocked. The whole army will be wiped out. What responsibility will you take?
