《论衡·卷十三·超奇篇》
因此鲁仲连用箭射信，燕将会自杀；邹阳上书辩解，梁孝王才会打开牢门放他。
是故鲁连飞书，燕将自杀；邹阳上疏，梁孝开牢。
Therefore, when Lu Zhonglian shot an arrow through a letter to challenge the King of Yan, he gladly killed himself; when Zou Yang submitted his letter in his defense, King Xiao of Liang opened the prison doors and set him free.
