The purpose of this study is to estimate the dimensions of the Protruding distance of Seven-layered Gongpo of Baoguosi Temple Main Hall in Ningbo, China, and to analyze the meaning of the dimension through the 『Yingzaofashi(營造法式)』and other similar cases. Through this study, it is clarified that the 『Yingzaofashi』 stipulates the limited use of the structural role of Ha-ang, but Baoguosi Temple Main Hall has expanded the structural role of Ha-ang actively by increasing the total Protruding Distance and effectively controlling the Protruding Distance of the layer where Ha-ang is placed. And as a result, the effect of lowering the total height of the protruding part was confirmed.
