Is the villa inclined 20 degrees southeast?

All right. According to relevant information, from the perspective of house lighting, the direction of the house should not be due south, but southeast, and the angle should be 15 to 25 degrees. It won't work beyond this degree. 20 degrees is more suitable for many areas in China. This kind of house is warm in winter and cool in summer, with plenty of light. Even in winter, sunlight can shine into the depths of the room, making people feel bright and warm. As soon as you enter the room, you will feel comfortable.
