They are weapons of Jianghu people and outlaws. Princes and nobles and romantic chivalrous men all wear swords. Sword is a gentleman among weapons. Hanging it in a conspicuous place such as the living room can ward off evil spirits, but if you hang a knife, the main punishment will hurt the murderer.
