Can you hang a gourd at the entrance of the building?

In geomantic omen, gourd is regarded as a plant that can ward off evil spirits, and the ancients often planted it in front of and behind the house. Modern physical experiments have proved that the gourd-shaped container can shield all kinds of interference from waves and radiation. Zhang used "Bao Hulu" to pour wine, which can not only exorcise evil spirits, but also preserve the taste of wine. Maybe you just want to get a state of mind to ward off evil spirits and keep peace, which has no effect on you. Don't worry about your voice, hehe.
