Feng Shui is a traditional culture, some of which can't be completely explained by science, but it can't be said in general. In house geomantic omen, some factors may have a certain impact on people's fortune, such as wealth, health, marriage and so on. But these effects are relative. We can't simply think that bad feng shui will definitely lead to bad results.
Therefore, if you are concerned about Feng Shui, you can ask professionals to make evaluation and suggestions, but you don't have to be overly superstitious. At the same time, maintaining good living habits and mentality is the way to really improve your fortune.
