《太平广记·卷七十二·道术二》
有一天，讲席刚刚开始，忽然有一个人推开门大喊大叫。这个人相貌粗黑，说话粗野，腰上插着赶骡的鞭子，好象是跟随经商的老客赶骡子驮货物的人。
时讲筵初合，忽有一人排闼叫呼，相貌粗黑，言辞鄙陋，腰插骡鞭，如随商客骡驮者。
One day, just as the lecture began, someone suddenly pushed open the door and shouted. The man looked rough and black, and he spoke rudely, with a whip for driving mules around his waist, as if he was an old guest who followed merchants to drive mules and carry goods.
