Abstract:Since there are no examples remaining, later generations can roughly use two types of media to understand the style of Han Dynasty wooden architecture, one is“Hanfu”, and the other is the excavated objects (architectural Artifacts, portrait stones and portrait bricks, etc.). However, the “antiyu”record in“Hanfu”does not mutually verify the phenomenon that the vast majority of the unearthed architectural Artifacts are rectilinear roofs.In view of this phenomenon, the author took Henan province as the research scope. Firstly, the 175 architectural artifacts mentioned in the book“Han Dynasty Architectural Artifacts Unearthed in Henan province”are classified and counted as a whole and their characteristics were summarized.Then compare and analyze them with the artifacts used in the emperor's funeral recorded in , and at the same time with the research on the selection of materials and the shape of the tomb of the emperor in Han Dynasty. Finally, it is concluded that the cause of this phenomenon is probably caused by the difference in the depiction objects of“Hanfu”and architectural artifacts. The“anti-yu”record in“Hanfu”should reflect the characteristics of higher-level buildings, such as palace buildings; the type of architectural artifacts can’t found in the imperial funerary are most likely to be spontaneously used by the people, and the rectilinear roof form reflected by them should be mostly the characteristics of folk residential architecture in Han dynasty.
