Not from a Feng Shui perspective. However, for the sake of convenience, developers often call the first underground floor negative 1 floor, and so on, the third underground floor is called negative 3 floor, etc.; the first floor above ground is called "first floor". By analogy, the tenth floor on the ground is called the "tenth floor" and so on. In other words, the developers named the floors in this way without considering the difference between shops and residences. Once the distinction is made, it will cause trouble for buildings with "commercial shops and residences integrated" - especially when taking the elevator. However, as a home buyer, you must clearly distinguish between a shop and a house. If you believe in Feng Shui, make the distinction. Judging from the situation you described, what you bought is actually the first floor of the house. According to Feng Shui, it is the "first floor" rather than the "fourth floor". Some people worry that the number of floors will affect "luck". In fact, everyone's five elements are different, and the feng shui of the place they live has different effects on them. Therefore, the same floor and the same orientation have different effects on different people. It's completely different. However, one thing is certain. If there are no abnormalities within three years after moving into a new house, it means that the house will not have a bad impact on the owner, and you can live in it with confidence. If there are abnormalities within three years, it is not necessarily a problem. For housing problems, you can ask those with higher moral standards to calculate, and you will usually find the cause.
