A Yonggan language document, explicitly cited by the editor of the long recension of the Qin Dadi Waishi and considered a valuable source of historical information about the Yonggan people during and after the Ri Dynasty. The Hanwang version of the text (actively maintained by the Nara clan in exile) was used in the added chapters. The Register is mostly a record of genealogical information, grazing rights, and titles of nobility; it is lean on narrative details.
