Feng Shui answer: Convex mirrors are for transformation, concave mirrors are for suction, and flat mirrors are for reflection. All Feng Shui items must be placed according to actual conditions. It is recommended that you do not hang a mirror on the bedroom glass first, as it may cause conflicts between the two families. It is best to buy a gourd, tie it with a piece of red cloth, and hang it above the windows and doors of your home. The gourd is a magical tool of Taoists and Feng Shui masters. It also adds auspiciousness to your home, getting the best of both worlds.
