The meaning of "cornice fighting angle" or "cornice warping angle"

One of the traditional forms of eaves in China is that the eaves, especially the eaves in the corner, tilt upwards. If the cornice, often used in pavilions, platforms, buildings, pavilions, palaces, temples and other buildings, the four corners spread out, like a bird spreading its wings, light and lively, so it is often called cornice. Cornice is one of the important manifestations of China's architectural national style. Through this special treatment and creation on the cornice, it not only expands the lighting surface, which is conducive to rainwater drainage, but also increases the upward movement of the building, as if it were a gas that lifted the eaves upward. The cornices in the middle layer of the building complex create a spectacular momentum and the unique soaring and brisk charm of the ancient buildings in China.
