In Feng Shui, opening windows in different directions has different meanings and plays different roles. 1. East-facing windows: The sun rises in the east, which breeds hope and vitality. East-facing windows can make the house full of yang energy, which means auspiciousness. 2. North-facing windows: North-facing windows are not good for the health of the residents, because the north belongs to the yin water in the five elements of Feng Shui. Opening windows facing north can easily allow bad air to enter. 3. South-facing windows: South-facing windows comply with the principle of facing south and are the most common window direction. 4. Southeast-facing windows: Southeast-facing windows are good for keeping the house warm in winter and cool in summer, which is good for your health. 5. Windows facing the west and northwest: Windows facing the west and northwest are vulnerable to cold wind in winter. 6. Windows facing the northeast and southwest: In these two directions, large windows are generally not opened, and small windows will have a relatively small feng shui effect.
