The floor of my bathroom is much higher than that of other rooms. I heard it's not good. How to solve feng shui?

As long as you don't drain the water from the bathroom to other rooms.

Let's not talk about the solution, just how to use it profitably. If there is a problem with the slope direction of the bathroom floor tile and water flows out, you can only make a water stop belt near the door to stop the water from flowing out. You can cut a floor tile of almost the same color, about 3 cm wide, and stick it with adhesive to prevent water from flowing out.

Do you think there are superstitions? If so, please pay a fortune teller to help you calculate. If you don't believe in superstition, as long as the water in the bathroom doesn't flow out, nothing will happen. Because I am an atheist, superstition comes from the Book of Changes, but many people can't read the Book of Changes. Later, when Kong Laoer translated Ten Wings, people understood the Book of Changes. Kong Laoer himself said, "Those who are easy are not gods.". It means that people who know the Book of Changes don't divine and don't believe in superstition, so everyone in the world relies on their own efforts and the help of friends, and there is no geomantic superstition.
