《后汉书·列传·张曹郑列传》
除非接受国君的命令，慰问亲族的疾苦，察看祭扫坟墓，观览省察野物，我何曾拄杖出过门呢？
自非拜国君之命，问族亲之忧，展敬坟墓，观省野物，胡尝扶杖出门乎！
Unless I receive the command of the sovereign, to comfort the sick and suffering of my relatives, to oversee the sweeping of tombs and the sacrifices, to observe and inspect wildlife, how could I ever have left the house leaning on a staff?
