Speak in feng shui; The 43rd floor is made of wood, but according to the geomantic omen of Bazhai, the floor should be in harmony with people's underground branches. In other words, it depends on your zodiac sign. For example, people born in the year of the sheep belong to the soil, which is unfavorable. The year of the horse is a fire, and wood makes a fire, which is auspicious and wishful.
If you follow Kong Xuan's geomantic theory; The fifth floor is not affected by the earth's atmosphere. According to the surrounding environment, talking about small Tai Chi is another matter. Frankly speaking; It's a small world where you live. The floor doesn't matter anymore!
