The eighth floor is unlucky: for example, it is in a mess, upside down, falling apart, talking, 78% off, 78% off, 78% off, 78% off, 78% off and so on.
The word "8" is homophonic and has a bad meaning: for example, if something happens outside the window, it will be followed by disaster, close call, crisis, relapse, chills and sudden death.
So for the eighth floor, it mainly depends on what buyers think. In fact, the eighth floor, which you thought was unlucky, was probably decided long ago.
Advantages and disadvantages of each floor
The lower floors, one to three floors close to the ground, are psychologically comfortable, but the pollution is also serious in buildings with slow air circulation, high shadow, high humidity and poor ventilation.
In the middle and lower floors, most people will think that the third floor is the most ideal, and it is here that a large number of harmful substances are gathered. There are much less harmful substances on the fourth and fifth floors, because they begin to sink or dissipate horizontally. This floor is ideal for most people. Once the elevator breaks down, it is acceptable to climb the stairs.
In the middle and high floors, the heating of residential buildings is rising, so it is the warmest above the sixteenth floor. In some old residential areas, the water pressure of high-rise residential buildings is generally low, sometimes water is cut off, and the room will be stuffy when the sunshine is long in summer.
