《后汉书·列传·李陈庞陈桥列传》
庞参到任，先去拜访他。任棠不和他说话，只把薤一大本、水一盂放在户屏之前，自己抱着孙子伏在户下。
参到，先候之，棠不与言，但以薤一大本，水一盂，置户屏前，自抱孙兒伏于户下。
Pang Can paid a visit to him after he took up his post. Ren Tang ignored him and just placed a large leek and a bowl of water in front of the screen door. He held his grandson in his arms and crouched by the door.
