First, the principle of bed placement actually has certain principles about the bed placement in the bedroom. Especially the older generation will pay attention to the placement of beds in the southeast, northwest and northwest, and they all have certain feng shui principles. Generally speaking, the bed is placed in the most reasonable position in the bedroom, and most people put it on the side near the window because it is more ventilated, sunny and has a better view. The most common way to put it is the north-south direction, because it is related to the actions people do during sleep. It can also fully ensure the quality of sleep, and the size and height of the bed must be selected, otherwise it will also affect the daily mental state.
Second, the bedside can't face east, but the placement of the bedside can't be anything, especially the bedside faces east. For example, judging from the meridians of the human body, the blood circulation itself is from top to bottom. If you sleep in the east-west direction, this is obviously contrary to the human blood circulation. In this case, it is likely that blood will run on the way, because the opposite direction will lead to some problems in the body. Moreover, the earth has a certain magnetic field, and the north-south direction is the most correct choice of magnetic field. If it's in the east-west direction, there will definitely be some bad phenomena during sleep, such as insomnia and even dizziness by car.
Third, the bed should also pay attention to feng shui. Therefore, the bed in the bedroom is generally north-south when placed. If your bedroom is too small, you have to choose the direction of things. And it is generally better to put it near the window, because it can be ventilated. But try not to put a full-length mirror in the bedroom and a mirror beside the bed. Because the mirror will reflect light, if you get up in the middle of the night, you are likely to be scared, which is not good.
