《汉书·志·食货志下》
犯法的人更多，等到五人相连坐都没入官府，郡国囚车铁锁，押送到长安钟官，痛苦而死的人十之六七。
犯者俞众，及五人相坐皆没入，郡国槛车铁锁，传送长安钟官，愁苦死者什六七。
There were more criminals, and when five people were arrested, they were all imprisoned in the government office. The prisoners of the counties and states were locked up and sent to the Zhongguan in Chang’an, and 67% of them died in pain.
