Documents and regulations on forensics dating mostly from the first three reigns of the Yuan. The work draws heavily from Xiyuan jilu and Pingyuan lu (qq.v.), which it criticizes in many places. The front part (13 entries) includes discussions (論辨) on various points, composed by Wang Yu himself (it is included in j. 1 in the Shen Jiaben recension). J. 1 (格例, 17 entries) includes model forms, recommendations and regulations (in the form of approved precedents) on forensic examination dating to the early Yuan period. (The text cites a precedent of 1315 and mentions the examination of the corpse of a pregnant woman done by Wang Yu in 1323, suggesting that Wang may have produced a revised ed. following the first ed. with 1308 pref.) Most ancient eds. are limited to the contents above. J. 2 (43 entries), as reconstructed by Shen Jiaben, is likewise composed of excerpts from the Yuan-period models for reporting called jie’an shi 結案式, and from Xiyuan jilu and Pingyuan lu. This section, which is absent from Ming eds., is comparable in contents and format to Xiyuan jilu, with a general statement on autopsies (檢驗總說) at the beginning, followed by the discussion of specific points. The Japanese annotated ed. is based on an undated Korean annotated ed. [postf. dated gengshen 庚申, probably the 1440 Ch’oe Malli postf.]; its contents (front part, j. 1 composed of 17 regulations [格例], j. 2 composed of 43 entries) are the same as those in the reconstructed Shen Jiaben recension. The notes inserted in the text in smaller characters are rather unsophisticated and obviously intended for a non-Chinese audience; they also mention the borrowings from Xiyuan lu. As noted by the Siku commentators, compared with Xiyuan jilu the present work contains useful new materials; the presentation has also been somewhat improved and simplified (with 43 entries instead of 53). In Shen Jiaben’s Zhenbi lou congshu ed. (which is used as a basis for Yang Fengkun’s modern recension), the entire material has been reorganized into 2 juan by including the front part in j. 1.
