It can not only dissolve the influence, but also ward off evil spirits. Buy a gourd, tie it with red cloth and hang it above your door. Gourd is an instrument of Taoism and geomantic omen, which can turn evil spirits into avoiding disasters and make money into treasure. It not only takes away the evil spirits of his family, but also adds auspiciousness to your family, killing two birds with one stone.
