Just like the ghost who often hears ... the air inlet window is opposite to the air outlet window, and the front and rear doors and windows are in the same line ... Open the doors and windows, whether it is hot air or cold air, as we all know, the wind blowing straight is definitely bigger than the wind blowing around the corner ... It is difficult to collect air ... If you don't pay attention at home, it will lead to cold and freezing ... and the dust outside will easily blow in. People look at your home from the outside ... there is no privacy at all ... you can't always close the doors and windows ... so you may stagger the doors and windows when solving it ... or cover it with curtains or potted plants, in fact, it is to cover up privacy, or to prevent the wind from blowing directly and weaken the wind.
