The reason is that people in China pay attention to sitting facing south, and the north yard belongs to the upper hand and the water, so it is impossible to put the stables in the north. So the north is generally the upper house, and the south is the lower house.
Advantages: Take the southwest corner as an example, the cowshed is generally dirty, but the morning sunlight can shine into the shed for exposure and disinfection, and it is also convenient for people to clean when it is sunny. When the sun sets in the west, it begins to shade and absorb heat again. Before dusk, the sun in the west can raise the temperature in the shed in disguise.
Disadvantages The southwest position is generally prone to nest wind, which can be regarded as a dead corner. Therefore, most feng shui books will list it as a bad place and rarely use it for living or as a bedroom.
Quote the third and ninth chapter of A Dream of Red Mansions: "The maid said that the water escaped from the stable in the south yard, which is irrelevant and has been saved."
