First of all, the orientation of the house is auspicious. There is no house in the southeast, north or south that has good lighting. The field in the north is a gold warehouse, which means the owner will get rich. The tomb in the north is no problem. This is a psychological effect and should not be ignored. The shape of the small window on the north side of the house depends on the shape. Generally, in rural areas, it should be eight-square, which is auspicious. It should not be too fancy, otherwise it will affect the internal wealth.
