Feng shui, what's wrong with the family toilet installed under the stairs?

The toilet should be quiet, the stairs are dynamic, and there is a conflict between static and dynamic.

Also, stairs are roads, and roads are unlucky for people. There is a toilet at the foot, and the future is uncertain.

There should be bookcases and art cabinets under the stairs. People's grades naturally improve.

Only on behalf of personal views, don't spray if you don't like it, thank you.
