Every study should have windows, because the room with windows, air and light are ideal, so the study should of course have windows.
But please note that the window of the study is not suitable for the desk, because the desk is not suitable for looking empty and learning from each other at home. Regardless of feng shui, as far as the environment is concerned, people are easily distracted by the scenery outside the window and it is difficult to concentrate on their work, which is particularly serious for teenagers who have not yet determined their identity. Therefore, in order to improve their attention when studying, parents should avoid pointing their desks at the window. The desk is facing the window, which will make you uncomfortable. You will recite the first page repeatedly when reviewing every day, but don't make a fuss, because the desk is just not facing the window, just a little off.
