Why is the eighth floor unlucky?
The owner who bought the building did not choose the 8th floor or18th floor out of his love for geomantic omen.
Problem analysis:
The floors 1 and 8 represent the so-called "seven ups and eight downs". Bad luck.
2.18th floor represents the so-called "eighteen layers of hell" in folklore. Bad luck.
Scientific and healthy statement: to buy a building in the urban area, you should choose floors above 12. Because of the influence of smoke and dust layer and noise in urban air, this height is basically the dividing point. The suburb is more than six stories high, almost.
Feng Shui is a superstition. "If you believe it, you will have it. If you don't believe it, you will have it." I haven't seen any unsold buildings on the 8th floor or18th floor! Do you understand?
I hope my answer can help you! Wish you a happy life!
