Abstract:This paper discusses two key issues in the structural system of the wooden-framed Yanfu Temple hall in the Southern Yuan Dynasty. Starting from the doubts about the current practice of double eaves and the corner of Xieshan, it is pointed out that although the present-day Hall is in the form of a double eaves mansion, however, the inference that the early prototype system should be a single eave with the two-frame system of the building preserved is made. The inference is made on the basis of an analysis of the causes of the current situation, and the unique historical and cultural values of the Yanfu Temple Hall are summarized, as an important node of the transition from the early period to the Ming Dynasty, the shape of the hall fully reflects the change of the construction thinking in this period, and still continues and retains some of the features of the early practice.
