Recently, my grandparents gave us a sword to ward off evil spirits. I heard that they bought a sword to ward off evil spirits when my father was a child. I think it's a knife. I don't know where to put it.
First, what do you do? This kind of thing is not suitable for everyone. All swords and guns are fierce. If you are not a soldier or a policeman, or you often deal with dead people, or you are not running away from anything, you'd better not leave these things at home, which will have an impact on you and your family.
Second: even if you know the above, the placement of items is not a middle wall, or even casually placed. Combine the structure of your house, north and south orientation, yin and yang. In short, the feng shui of your home should be put right, so as to achieve the ideal effect, otherwise it will run counter to it. This is not advocating superstition, but since you want to place these things, you'd better be careful.
