Why are all the houses in the south of the Yangtze River with white walls and black tiles? Is it related to his environment and climate?

Ancient China people's understanding of the whole world was summed up as a unique theory, namely the theory of Yin-Yang and Five Elements. People think that everything in the world is divided into yin and yang, and the world is composed of five elements: gold, wood, water, fire and earth, all of which complement each other. Ancient people? Building pays attention to the theory of geomantic omen, precisely because of the geographical location, climate and economic factors in the south of the Yangtze River, which forms the characteristics of white walls and black tiles.

Specifically, first of all, the gold in the five elements is white, sitting in the west, and the totem is a tiger, which has the function of ward off evil spirits. The wood is blue, sitting in the east, and the totem is a snake (also known as a dragon), which has the power of rejuvenation. The water is dark, sitting north facing south, and the totem is a turtle, which has the function of nourishing and conserving. Flaming red, sitting south, the totem is firebird (phoenix), which has a strong transpiration effect. Khaki, sitting in the middle position, the totem is a dragon, which has the function of bearing everything (China, hence the name China).

China's territory is all in the north latitude, and the sun is always in the south, which was discovered by the ancients? First of all, it is most suitable to sit facing south. Because the houses in ancient China were basically wooden structures, but the wooden structures were extremely afraid of fire, so the ancients thought that they were built with black (water) tiles. Buildings can play the role of fire fighting and extinguishing, eliminating or reducing the probability of fire. Followed by feng shui, although ancient man-made houses will look at feng shui in advance, they think it is impossible to completely avoid the invasion of evil spirits. Moreover, the geomantic omen in nature will change with age. If all four walls are white (tiger), it can ward off evil spirits. It should be said that this is the deep consciousness root of white wall and black tile.

In addition, there are many high temperatures in the south of the Yangtze River in summer, unlike northerners who burn kang in winter, and black tiles can play a certain role in heat insulation. Just like Arabs, they live in hot and dry desert areas and wear black robes. Moreover, there is a lot of rain in the south of the Yangtze River, so houses are generally brick walls. Brick walls are not afraid of flooding, and they are permanent, while whitewashed bricks (ancient exterior wall coatings) can prevent moisture and insects, set off the green environment of water system areas, and form an elegant beauty, so there are more white walls and black tiles in Jiangnan.
