What are the feng shui of window design?

In geomantic omen, opening windows in different directions has different meanings and plays different roles. 1. Window facing east: The sunrise in the east breeds hope and vitality. Windows facing east can make the room full of yang, which means good luck. 2. North-facing windows: North-facing windows are not conducive to the health of residents, because the north belongs to yin water in the five elements of geomantic omen, and opening windows to the north is easy to make bad air enter. 3. South-facing window: South-facing window conforms to the principle of sitting north facing south and is the most common window orientation. 4. southeast-facing windows: southeast-facing windows are good for the house to be warm in winter and cool in summer, which is good for health. 5. Windows facing west and northwest: Windows facing west and northwest are vulnerable to cold wind in winter. 6. Windows facing northeast and southwest: Generally, large windows will not be opened in these two directions, and small windows will have less feng shui effect.
