《雲夢睡虎地秦墓竹簡‧封診式‧經死》篇，描寫士伍丙自縊身亡，其里典發現後，向縣裡寫了份爰書。於是縣廷便派令史及牢隸臣，陪同丙之妻及女兒，一同前往勘驗。這份爰書中，極為細膩的描述了勘驗的程序，及解釋所有勘驗內容的目的。此篇內容的出土，不僅使我國的法醫學史更往前推進。同時我們也發現，秦代的法醫勘驗工作已相當成熟，且勘驗的過程，也已經與司法程序相結合。因此，《經死》篇的內容，除了說明勘驗程序，也是研究秦代法律文書、司法程序，及認識我國法醫學史的重要文獻。

There is a text called "Jing Si," part of the document "Feng Zhen Shi" found among the Qin bamboo strips unearthed in Shuihudi. It contains a record of Shi Wubing hanging himself. After he was discovered, a notice of the incident was sent to the county government. The county sent two officials (lingshi and laolichen) to accompany the deceased man's wife and daughter in examining the scene. The report describes in detail the process of investigation and provides explanation of the various parts of the examination. The unearthing of this text pushes our knowledge of ancient Chinese law and medicine even further back in history. It also reveals that a relatively mature investigation process was in place during the Qin dynasty, as well as that investigations were already linked together with the civil law. Therefore, "Jing Si" is an important document, not just in understanding the investigation process, but also in researching Qin legal documents, civil procedures, and the history of law and medicine in China.
