The mystery of the curved roof of ancient buildings in China

The roofs of ancient buildings in China play a particularly important role in the building facade. His far eaves, elastic eaves curves, slightly curved roofs formed by lifting frames, slightly warped corners (when you look up, the corners are spread like bird wings, so it is called "wing corners") and hard mountains, suspended mountains, rest mountains, temples, peaks, horizontal ridges, roofs, double eaves and other roofs. Through various combinations of roofs, the shapes and outlines of buildings become richer and richer. Looking down from the air, the roof effect is better, that is to say, the "fifth facade" of China architecture is the most attractive.
