Whether the study table in the child's study should be placed with the window or with the back against the wall? I can only choose which position is better.

In terms of Feng Shui, it is better to have your back against a wall than to face a window. You will feel safe with your back against the wall. If you have your back against a door, you will feel worried about being peeped, and you will be restless when studying. Be careful, you can face the window sideways but not facing it. The window is an air vent in the house, which will bring in the angry and disharmonious air. Especially the windows that open to the outdoor sidewalk will bring in more disharmonious air, which is very important for learning. It doesn't have a good impact.
