Feng Shui belongs to Kan Yu. The so-called Kanyu refers to the magnetic field relationship formed by geography and the orientation of objects. Don't think about everything based on Feng Shui. You will be full of doubts and panic all day long. It has nothing to do with Feng Shui when using a quilt on rainy days, but the air is humid on rainy days, and the cotton wool will easily breed bacteria when it gets damp, which is bad for your health. So it is best not to use a quilt on rainy days. If it is necessary to use a condom, then after using it, you should find a sunny day with good wind and sunshine and quickly dry it to kill viruses and sterilize.
