Windows, we often say: "eyes are the windows of the soul." Losing eyes means losing all hope, and the windows of a house, like people's eyes, play an indispensable role at home. Air and sunshine are the basic elements of human existence. If people breathe stale air for a long time or are in an environment with insufficient light, they will easily get sick or lose their spirits. Therefore, the house must be equipped with windows, and the design of windows is not as big as possible. Attention should be paid to the convection of air in the house, that is to say, the windows should be facing each other, for example, opening a window facing north or facing east and west, so that the air in the house can circulate and the residents can be healthy.
The relationship between a door and a window is just like that between parents and children. The door "looks like a parent's mouth" must be more impressive than the window "looks like a child's mouth", otherwise the child will rebel. The ratio of the number of windows to the number of doors will affect the harmony of the family. One window is enough, three or more windows will make family unhappy-talkative. Too many windows mean that children criticize each other and quarrel with their parents. If the window is too big, there will also be family unrest, because children don't listen to their parents. If a large window is divided into fine grids or fitted with a whole piece of glass, it is lucky.
