Cover with screens, decorative cabinets and other objects. If you can't put down the porch, you can use a screen or a decorative cabinet, but the decorative cabinet must have a back plate, that is, you must hang curtains without ventilation. If the porch is a long corridor, you can hang bead curtains and gauze curtains! After the entrance was blocked by the porch, the direction of air flow changed and the intensity of air slowed down, making it look forward to staying at home for a long time. The porch position can also be used for screens and decorative cabinets. In addition, offices are generally single rooms, so it's okay to open the door and see the window. There is no need to go to other rooms. However, in order to solve the problem of direct traffic, many units have also made a porch at the door, which is the unit signboard. That's good.
