According to Feng Shui, can children store books under the bed?

I don't know feng shui. I have only heard that Feng Shui depends on the whole, room, environment, name, occupation and gender. Never heard of paying attention to the layout of only one bed.

From a health point of view, walking along the magnetic field in the north-south direction of the earth is generally good for sleep. Don't sit by the window for fear that you will get sick as soon as the cold wind blows.
