My dad said it was rain flower stone, but I don't believe it. What is this? What did it do to the house? be online

No matter what stones are indoors, they are not good for Feng Shui, but no harm is good! Those so-called "stones" to operate are purely nonsense and deceptive. The stone itself has nothing to do with feng shui. There are big stones in some places in the yin house or the yang house, which have certain effects, which are different from the small stones at home. This is not a conceptual problem. Whether the rain flower stones are all the same!
