The geomantic omen of the house also has the problem of a vacant room. This kind of house is full of yin, not yin in religious belief. I mean, there is no ventilation in the room, and the air is not good.
If you don't live in a house for a long time, you just need to pay attention to ventilation, a variety of living plants, and clean it regularly. When you come back to live, you should open the window and ventilate for a while to avoid inhaling unclean air that stays indoors for too long. If possible, buy a watering can for watering flowers, which can generate water mist, put some water in it, spray some water on the open space of the room, restrain the floating dust in the room and replenish some water to the room. After that, people will go out for a walk and wait 15 to 30 minutes before going back to rest.
