《智囊(选录)·上智部·赵普　李沆　陆九渊》
原文宋朝赵普任宰相时，在座位后面放置了两个大缸，凡是有人送上建议国家利害的疏奏，大都被扔入缸中，等装满缸后就在通道上把文书烧掉。
赵韩王为相，置二大瓮于坐屏后，凡有人投利害文字，皆置其中，满即焚之于通衢。
<8>. In the original text, in the Song Dynasty when Zhao Pu served as prime minister, he placed two large jars behind his seat. Any time anyone submitted a memorial on state affairs to him, he would throw most of them into the jar. When the jar was filled, he would burn the documents in the corridor.
