The Wenxian tongkao by Ma Duanlin of the Yuan dynasty is a monumental work of scholarship in Chinese historiography. It has invited many discussions among scholars in academic circles. The topics of discussion include Ma Duanlin's historical thought, the composition principles of his opus, its value as a source of history, or the merit of the monograph on Bibliography (Jingji kao 經籍考); but few attention has been given to the monograph on Historical Comments (Shilun 史論). This paper is focused on the latter topic. In a breakdown of nine sections, it will examine its principle of composition, amendment of historical sources, the perimeter of his historical comments, to be followed by comments on the Bibliography monograph. It will conclude with an assessment of the shortcomings and limitations of this work, and also a discussion of the significance of this work in college teaching in modern times.
