The phenomenon of temporal and spatial superimposition and integration of Northern Dynasties elements 
and Tang Dynasty statues in Cave 45 of Huangze Temple in Guangyuan makes it present a unique artistic style. This artistic phenomenon not only showcases the diversity of the grotto statues but has also drawn academic attention to the exact construction date of this cave. The special hybrid spatial structure that combines the “three niches on three walls” layout with a central pillar in Cave 45 demonstrates the diversity of architectures in Buddhist grottoes from the Guangyuan region during the Northern Dynasties period. Furthermore, the decorative patterns on the central pillar show strong similarities to styles prevalent in the grotto art of the Central Plains during the late Northern Wei dynasty, reflecting the influence of the sinicized artistic style represented by the Longmen Grottoes. Therefore, the architectural form and decorative imagery of Cave 45 serve not only as crucial evidence for its dating but also as important proof for the southward transmission of the grotto art of the late Northern Wei Dynasty from the Central Plains to the southwestern regions.
