Do you want to change the bathroom below into a kitchen? I heard that this feng shui is not good. Why not? How to solve it? How to treat water better?

I don't quite understand. I don't think it's appropriate to change the bathroom into a kitchen. The water in the upper bathroom comes down, and the odor in the lower bathroom comes up, which has a great influence on the kitchen. In case of damage, the kitchen will suffer.

It can be transformed into a storage room, but the walls of the original ventilation shaft and sewer pipe can be transformed by ensuring that they are intact and packaged.
