Different versions of the book exist, but the earliest existing version was published during the Yuan Dynasty, containing fifty-three chapters in five volumes. The first volume describes the imperial decree issued by Song Dynasty on the inspection of bodies and injuries. The second volume contains notes and methods on post-mortem examinations. The third, fourth, and fifth volumes detail the appearances of corpses from various causes of death and methods of treatments to certain injuries.
