What's feng shui about the stairs in the corridor?

This is a topic in Feng Shui, because stairs are often used in daily life, so the position of the building represents constant movement. If the lucky star at home flies to the location of the stairs, it will be prosperous. If the evil star flies to this position, because the location of the stairs often moves around, it will incite the ferocity of the evil star and bring bad luck to the family, such as lawsuits and blood loss. So the feng shui of the stairs must be checked, and be careful! I hope my answer can help you! Help you have good luck. Good luck.
