You can't hang a sword in the bedroom. In feng shui, swords are often used to block disasters. If there is no suffocation, they don't necessarily need to be placed. Of course, it doesn't have to be displayed as a collection, but it should be noted that it is best not to cut the sword, otherwise it will easily lead to mass annihilation. If the blade has been cut, it must be put in the sheath or brocade box, and the blade must not be exposed. Traditionally, the sword of the town house should be placed in the study.
