According to the pref., this work by an experienced legal muyou had been copied again and again, hence many errors, which the editor tried to fix based on a good-quality ms. he had been shown—hence all the entries that end with such indications as “modified” (修改) or “augmented” (增). The work, which is organized by topics along the lines of the Penal Code, provides concrete advice on every aspect of the judicial procedure. An introductory section (the longest of the text), entitled “Managing cases” (辦案), deals with such general matters as procedural principles, general information, judicial officials, and the judicial system. It is followed by a section on general principles (名例) and by information on specific types of crimes related to marriage, land, grain storage, buying and selling, ritual matters, military issues, courrier issues, banditry, homicide, affrays, litigation, bribery, fraud, miscellaneous crimes, arrests, imprisonments, punishments, and more. Examples and additional explanations on various issues are inserted in small characters throughout the text. The sections on general principles, like those on specific crimes, consist of miscellaneous thoughts on the topic at hand, often useful but with relatively little organization or analysis. There are interesting considerations on collecting confessions (rules to obey, things to avoid). The work appears helpful for understanding the Code concerning a particular crime, less so on the system as a whole. An appendix provides a useful discussion of the role of the legal secretary and his importance to the legal system.
