《颜氏家训·音辞篇》
梁朝有一位侯王，曾经与梁元帝一起饮酒戏谑，他自称 痴钝 ，却说成 飔段 ，梁元帝戏答他说： 飔不同于凉风，段也不是干木。
梁世有一侯，尝对元帝饮谑，自陈 痴钝 ，乃成 飔段 ，元帝答之云： 飔异凉风，段非干木。 
During the Liang Dynasty, there was a vassal king who once drank alcohol and joked together with Emperor Yuan of Liang. He called himself “chitu,” but pronounced it as “que duan.” Emperor Yuan of Liang jokingly said: “Que is not the same as a cool breeze, and duan is not dry wood.”
