"Trees" need to receive sunlight and absorb water before they can continue to grow. Therefore, the main room for children to study, whether it is a bedroom or a separate study, should be bright. Because wenchang star is dominated by green, the color of the room can be dominated by green, but not too much pink, red and dark black. It is best not to stick too fancy wallpaper on the walls, so as not to be impetuous and unable to concentrate on study. In addition, we should pay special attention to the fact that the desk cannot be placed under the beam or directly facing the air conditioner, which is very unfavorable to children's study and health.
