《资治通鉴·汉纪·汉纪五十六》
李孚砍下树枝作为责打人的刑杖，系在马旁，自己戴上武官用的头巾，率领三名骑兵，黄昏时到达邺城。李孚自称为都督，从北边进入围城的曹军大营，顺着标志，向东巡查，一路上不断叱责守围的将士，根据违反军中法纪的轻重，分别给予处罚。
孚斫问事杖，系著马边，自著平上帻，将三骑，投暮诣鄴下；自称都督，历北围，循表而东，步步呵责守围将士，随轻重行其罚。
Li Fu cut down some tree branches to use as a staff to beat people, tied them to his horse, put on a military scarf, and led three cavalrymen. At dusk, he arrived at Ye City. Li Fu claimed to be a general, and entered the Cao troops' camp besieging the city from the north. He followed the markers and patrolled eastward, constantly berating the soldiers who were guarding the siege on the way, and punishing them according to the severity of their offenses.
