First of all, it is not good for a small high-rise house to live on the fifth floor. It depends on the orientation of the whole building and your own house. Not all the fifth floors are bad! There will be a good fifth floor and a bad fifth floor.
Second, the fifth floor is the lucky building. If it is a bad floor, it just doesn't mean it is fierce.
Third, whether the house is healthy or not is related to the influence of the buildings around the house on your own house, not the floor.
If you say that Mr. Feng Shui says that the fifth floor is bad for your health, it is because the fifth floor is short and other buildings around it have washed away the house, but if you live higher and other buildings are not as tall as yours, there will be no washing away. This is credible.
If it weren't for this reason, you wouldn't believe it!
