Dear master Cecil Lee, Master, I have inherited samurai swords (katana)with their rest standand found them asan artistic pieces suitable for display in living room.. The problem is, their sheaths or coering were missing and they were exposed, when resting in their stand, they were blade-side up. Because I believe in Feng Shui, their display might cause poison arrows, but I want them to be maintainedas an aesthetic and familial historical piece. I made sure the swords on display never pointed towards any door or corner, and instead confined them inside a wood and glass cabinet...Does this made them neutral? Any advice whether to keep them permanently, but I don't want them inside the bedroom. Thanks you and warm regards. Your follower, Lam Ngan Lung.
