Which direction is the head of the bed better?

Simply put; In our country, there are different opinions about the orientation of the bedside. Some people say that the sun only rises in the east and never sets in the west. Some say it's sunny in the south, while others say it's not in the north. The magnetic field in the north is not conducive to physical and mental health, and some people say that the north is good. Lao Huang Li said that beds don't cross the window. Now there are beds of all sizes, as well as beds that cross the window. East, west, south, north, which direction is the bedside, etc., there is no unified statement, but in some areas of our country, it is not suitable to press the bed under the beam. Personally, I think that there are not many people who really understand Feng Shui in China, and there are many people who have a little knowledge, and there are also many people who talk and lie. Personally, I think we can choose the best seat according to the family housing space.
