Li Zhirong (Peking University): Dazu Beishan 245 Buddhist Sutra is disguised as the earliest and largest grotto in Dazu stone carvings that inherited the Buddhist system of the Tang Dynasty. Since people began to make a scientific investigation of Dazu stone carvings, Dazu stone carvings have been highly valued and praised for their magnificent scale and exquisite carving art, especially the large number of architectural images in their carving contents, which have attracted the attention of ancient architectural researchers in China since the 1940s. Both Mr. Liang Sicheng and Mr. Gu used the image data of 245 stone niches to discuss the architecture of Sichuan in the Tang Dynasty, which Mr. Liang also used as an important contrast with the image of Dunhuang architecture in the same period. Because the research of these predecessors is not based on close observation, their understanding and description are still debatable. From the perspective of methodology, I think that we should pay full attention to the origin and background of Buddhism when discussing the problems in architectural history with the architectural image materials reflected by Buddhist grottoes. Wang Huimin (Dunhuang Research Institute, China): 245 niches in Dazu North Mountain were built in the late Tang Dynasty and well preserved. Its content and art play an important role in Dazu stone carving. The construction period is also the heyday of Chengdu Dasheng Temple, and the two can be compared. It may have been built by a mass organization, which seems to be in the "center" and revolves around the distinct theme of western pure land. Exquisite art made it a representative work of Dazu stone carving at that time, and its architectural performance was paid more attention by researchers. Chen Yunv (Taiwan Province Province, China? 9? National national cheng kung university): Fowan 130, Dazu Beishan, also known as the Eight-armed Goddess Cave. Although it is called the Statue of Goddess, its hands are full of fighting weapons, which can be said to be the combination of the two images of goddess and god of war before the Song Dynasty. According to the literature, what was seen before the Tang and Song Dynasties was either the Goddess of Heaven or the God of War. Why does Dazu Grottoes have the above-mentioned fusion modeling? Perhaps the war at that time made it gradually needed. Professor Li (Dazu County Local Records Office): Dazu stone carvings, especially Baodingshan Grottoes, were deeply influenced by China folk culture when they were produced, which in turn profoundly influenced the changes and development of China folk culture. It completed the final course of nationalization and secularization of religious culture. Here, religious culture and folk culture are inseparable.
