This depends on how you look at it. If it is a folk custom, we have a saying that the seventh floor is better. Take Feng Shui as an example. In the tricks, 1 is the beginning, 2 is the sum number, 3 is the auspicious number, 4 is the constant, 5 is the number of people, 7 is the variable, and 9 is the pole number. On the contrary, 6 and 8, which we often regard as auspicious, are not good numbers, because they are not clever in tricks, so many auspicious words have been added. The ancient emperor was only 95, the jade emperor was 99, and the mortal life was as high as 7. After 7, it began to decline. Some people also say that 7 is a variable, and poverty changes. 6 means poverty and exhaustion.
Let's choose the seventh floor, even if it's a flight of stairs.
