It is generally believed that the bed should be placed in the north-south direction, because the geographical magnetic field is in the north-south direction, ensuring that the sleeping direction of the human body is consistent with the direction of the magnetic field lines can make people fall asleep more easily. Generally speaking, the orientation of the bed is north, east or west, and these three positions are all suitable. If the bedroom is not a south window, it can also be south, because the head of the bed is not suitable for facing the window, otherwise it will be discouraged. If you follow the characteristics of the zodiac and the eight characters, you can also face four even positions.
