How about putting a knife in the bedroom for feng shui?
Some people like to collect some knives or swords, and some even like to hang them in their rooms. This is actually a matter of geomantic omen. Generally speaking, swords are suffocating, so people should not collect them easily, unless you have a sheep blade in the Chinese character, and it is used, or you are engaged in political and legal work or martial arts, you can collect it and put it in your room. Except for this kind of person, most people put their swords in their rooms. I am prone to stress, headache, insomnia and trauma at work. Therefore, it is best not to put or hang swords in the room, which is a big taboo.
