Described in a poem by Li Dou, a poet in Qing Dynasty? Three rooms, five pavilions, cornices on three sides, and glazed bamboo tiles and phoenix drops in Longgou. ? Cornice is a stroke of genius in the history of ancient architecture in China, and cornice is a representative culture in the history of architecture in terms of appearance and practicality.

We can see this in many places. Cornice? For example, many temples and palaces will incorporate such elements. Why do ancient buildings in China always have upturned cornices? I think it can be analyzed from the following points:

1. From an aesthetic point of view, when a cornice is raised, the whole roof looks light and natural, less dull and more charming. The eaves bulge to form a perfect arc, just like birds flying high, which makes people feel a good feeling. The ancients were also very particular about the length of cornices. Increasing one point is too long and decreasing one point is too short? It fully explained the craftsmen's pursuit and strictness of beauty at that time.

In addition, if you look closely, some shapes are also designed on the cornice. Some are? Bird? Some are still soaring? Dragon? It gives people a sense of upward support, and people have to admire the wonder.

Second, the upturned eaves are conducive to indoor lighting. The eaves of ancient buildings in China are far-reaching, in order to let more light into the house. The ancients used the method of upturning the eaves in the opposite direction and had to admire the wisdom of craftsmen at that time.

Third, the roof inclines upward, which can effectively alleviate the situation of rain splashing. In contrast, the cornices in the south are somewhat different from those in the north. There is a lot of rain in the south, and the eaves of buildings are high. The rain on the roof can be thrown as far as possible (parabola is the best curve) to reduce the damage of rain to the foundation of buildings.

The cornices in the north are not as high as those in the south. The eaves themselves are relatively straight, but the upturned cornices are still quite prominent. In addition, because of the snow in the north, the straight eaves after snow will not cause pressure on the tiles at the end.

These are the reasons why the ancient buildings in China have cornices. China's culture is profound, and various designs of ancient buildings have far-reaching influence on human history, which is worth exploring.
