《明史·列传·卷一百二十九》
这个时候，厂卫继承冯保的余威，随便接受老百姓的诉讼官司；巡抚巡按官员寻访察问奸情，大多连累无辜的人；有关部门断案，往往在本罪之外加重刑罚，皇帝喜欢用 立枷 ，重达三百多斤，受这刑的人马上就死。
当是时，厂卫承冯保余威，滥受民讼；抚按访察奸猾，多累无辜；有司断狱，往往罪外加罚；帝好用立枷，重三百余斤，犯者立死。
During this time, the Imperial Guards and the Eastern Depot, relying on the authority of Feng Bao, arbitrarily accepted lawsuits from the people. Censors and inspectors, in their investigations of scandals, often implicated innocent parties. Courts tended to impose punishments that were disproportionate to the crimes committed. The emperor was fond of using the cangue, which weighed over three hundred catties. Whoever was subjected to this punishment died almost instantly.
