《梁书·列传·卷十》
杨公刨曾经登楼观战，城中守军远远望见他的麾盖，就用神锋弩来射他，箭头射穿了他坐的交椅，左右随从全都大惊失色公则不经意地说： 差点射中了我的脚。 
城中遥见麾盖，纵神锋弩射之，矢贯胡床，左右皆失色。公则曰： 几中吾脚。 
Yang once climbed to the tower to observe the battle situation. The defending army in the city saw his canopy from afar and shot him with a Shenfeng crossbow. The arrowhead went through the chair he was sitting on, and all his entourage were terrified. Yang said casually: Almost hit my foot.
