The toilet is squatting next to the living room, but separated by a wall. Is this about feng shui? Please give me some advice!

That's totally fine. Don't care about these little things, even if there is a problem, these little things can be completely ignored. There is a saying in Feng Shui that a power is precious, and those who are fierce are afraid. This means that Feng Shui depends on the key points, not to mention several key points. Even if a key point is done, other murderers have to be awed by this good heart.
