A series of 20 model cases (most of them capital) from Yunnan in the Jiaqing and Daoguang periods, compiled from the Yunnan archives by Yilibu while he was Yun-Gui governor-general. As stated in the compiler’s pref., the aim of the work was to present Yunnan and Guizhou officials with examples of investigations and judicial decisions dealing with ordinary cases—as opposed to affairs raising complex technical or theoretical issues of law, as in most such anthologies—that would help inexperienced officials avoid rejection by the ministry and all the ensuing trouble in terms of new investigations, moving prisoners back and forth for further interrogation, and so on. The cases, all of them approved by the ministry, are classified by type of crime. The text consists of full quotations of the confessions extracted from the defendants, accusers, and witnesses, and of the conclusions reached at each step of the procedure, with some comments written in the upper margin detailing the proper way to proceed, how to write down the depositions, etc. In other words, this not a collection of “judgments,” but rather of dossiers ending with a judgment proposal. For a sequel, see under Xue’an chumo xubian.
