In developed cities such as Hong Kong, living spaces tend to be small, leaving limited options for storing items not used every day, such as winter clothes, Christmas decorations and sports equipment. For people who have the luxury of a storeroom in their home, some fung shui principles should be followed. Ideally, a storeroom should not be located opposite the main entrance or be at the centre of the home, as this may lead to the accumulation of stagnant energy. A storeroom should not be so full the door can't be closed and it should be aired and cleared regularly. While some people have more difficulty than others in letting go of personal items, it's essential to ask ourselves whether these items are still relevant to our lives or if they could be more useful to others. Keeping electrical appliances that no longer work and cannot be fixed, for instance, serves little purpose. Remember that areas behind doors (including the main door) should not be used for storage. Doors that are unable to open fully suggest obstacles for the home's occupants, so think twice before placing your vacuum cleaner or tennis racquet behind your bedroom door.
