Can I put a black walnut coat rack in the Feng Shui bedroom at home?

Coat rack, these have no special significance! It used to be said that mahogany can ward off evil spirits at home at ordinary times. But few people do it now. Moreover, peach trees that ward off evil spirits all have specific shapes. Definitely not like a coat rack! Therefore, putting a mahogany coat rack in the bedroom is not good or bad.
