Referring to various works during the Earlier and Later Han Dynasty, the author details categories of historiographical writing, i.e., the category of classical, official, and miscellaneous history, and different branches of analysis and interpretation. The book expatiates chapters on astronomy, mathematics, geography, agriculture, and medicine. Among these are the three theories on sky, the mathematics, map drawing, ox-plowing, an agricultural treatise, water project examinations, and the process of knowledge transfer and advancement in medicine during the Han Dynasty.
