《北史·列传·卷七十五》
有僚属吏卒贪赃枉法，在官署内部劫掠偷盗者，不问情节轻重，都关闭在地窖中，在粪便脏物中躺卧，让他们遭受痛苦，不是自己死了，始终不得放出。
或僚吏奸赃，部内劫盗者，无问轻重，悉禁地阱中，寝处粪秽，令受苦毒。自非身死，终不得出。
There were officials and soldiers within his administrative office who were corrupt and breaking the law, robbing and stealing. Tian Shi did not consider the severity of their crimes, and all of them were locked up in dungeons, lying in the excrement and filth, making them suffer until they died. He would not release them.
