The room is one centimeter lower than the living room floor. Does feng shui have an impact?

First of all, I personally feel that if the ground is in the same space, it is best not to be scattered, which is not good for safety or feng shui. But what the landlord said was the room, which should be the bedroom, one centimeter lower than the living room floor. I don't think it is a big problem. Belonging to two spaces, there are doors and doorstones in the middle, which is only one centimeter, which is basically negligible.
