How about keeping gourds in the building?

Gourd is an auspicious geomantic plant in geomantic omen, which is homophonic "Fulu", meaning auspicious and safe. Moreover, gourd can absorb the evil spirits, evil spirits and evil spirits in metaphysics and geomantic omen, so it is beneficial to plant gourd at home. Sun-dried gourds can be hung on doorways and windowsills to ward off evil spirits.

But gourd is a seasonal plant, and now is not the time to plant gourd, so it is more difficult to take care of it now. Gourd requires high moisture content and cannot be exposed to the sun for a long time, so be very careful when planting gourd.
