Is it an element or something that Gu Jianjun's roof corners are upturned?

There is no morality. This is called cornice, which 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, is conducive to the drainage of rainwater, but also increases the upward movement of the building, as if a gas 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. Cornice is an important part of traditional building roof modeling in China. Among the traditional buildings in China, the shape of the roof is the most prominent, and the roof accounts for a large proportion in a single building, which can generally reach about half the height of the facade. The beam-frame combination of ancient wood structure can naturally make the top of the slope form a curve, not only the slope surface is a curve, but also the front ridge and eaves end, and the eaves can also be added at the corner where the eaves turn. The huge roof composed of beams and frames, as well as the gentle curve of the top of the slope, the straight roof ridge and the upturned cornice, make the roof the most remarkable form feature of China architecture.
