Since the Yuan Dynasty, the proportion of bucket arches in buildings in China has greatly decreased (the evil Mongols), which can also be seen from the slope change of the roof. Japan, on the other hand, has maintained its style since the Song Dynasty. As for the dazzling deep relief and round carving of Yangming Gate, Japanese architectural circles also believe that it is related to the Baroque style they came into contact with when communicating with the West.
Therefore, it can be said that the exaggerated proportion of the bucket arch structure was originally a patent of China.
