In traditional geomantic omen, it is very particular about "hiding the wind and gathering the gas". Therefore, a relatively small bedroom can prevent airflow loss, which is beneficial to the health of the owner. Since ancient times, there has been a saying that there are many people in the house.
If the bedroom area exceeds 20 square meters, it will not only damage the owner's health, but also reduce his judgment and have a negative impact on his mood. Therefore, it is best to control the area of the bedroom below 20 square meters.
