Can't peach branches be put in the bedroom to ward off evil spirits?

Yes, but it is not recommended. My personal recommendation is as follows: 1. Portrait of Zhong Kui; 2. Door gods (there are many kinds of door gods, and one in Weichi Gong is very good); 3. Sword (mahogany is recommended, and black iron sword is also acceptable); 4. Idols (idols, not Buddha statues, Buddha statues are not recommended); 5. Small bronze mirror (don't face yourself, hang it at the top of the door and look out, or hang a small pair of scissors in front of the mirror); 6 Ai Chang; In fact, if you want to ward off evil spirits, you can sincerely remember the buddhas and bodhisattvas, which is more effective than any ornaments.
