Usually the bedside is next to the wall, or there is a bedstead, or there is a physical cabinet, indicating that there is a backer behind it. The window is also the air outlet of the room, sheltering from the wind like an arrow, and the fairy is also afraid of the wind behind her head. If the bed in the bedroom is not supported or close to the window, it is easy for the sleeper to fall asleep and dream more.
If you don't close the window when it's windy and rainy, it's easy for people in the house to catch cold and get sick. In addition, if there are children at home, children are naturally active, and it is easy to borrow beds and climb windows, resulting in dangerous accidents.
The strong light outside the window will directly affect the quality of sleep. If you don't close the window, the noise outside the house can easily be directly transmitted into the bedroom through the window, and the noise outside the window will obviously be much louder than the noise inside.
If there are multiple windows in the room, you can seal one of them. If there is only one window in the room, you can hang a thick curtain next to it. Or you can hang a gourd or five emperors' money, six emperors' money and ten emperors' money behind the bed.
