No door between the balcony and the living room, okay?

It is necessary to install a door between the living room and the balcony, because:

1. Dust and other things outside can be prevented from floating indoors.

2. It is a good anti-theft facility. If a thief breaks the door after closing the door, it will alarm the neighbors and play an early warning role.

3. If you have children at home, you can prevent the children from running outside when they are not.

4. isolate the temperature difference between indoor and outdoor. for example, when air conditioning is used in the living room, the door can play a role in heat insulation.
