《资治通鉴·汉纪·汉纪四十一》
有人问虞诩： 以前孙膑使用过减灶的计策，而您却增加灶的数量；兵法说每日行军不超过三十里，以保持体力，防备不测，而您如今却每天行军将近二百里，这是什么道理？ 
或问曰： 孙膑减灶而君增之，兵法日行不过三十里，以戒不虞，而今日且二百里，何也？ 
Someone asked Yu Xu: "Sun Bin used a strategy of reducing campfires, while you are increasing their number; military strategy says that one shouldn't march more than 30 miles per day in order to maintain stamina and prepare for emergencies, while you are currently marching over 200 miles per day. What is the reason for this?"
