It is said that crystal ornaments are feng shui. Is it true?

It's really feng shui. Crystal is a kind of gem with extremely high hardness, which can hardly be cut at will, but the ancient Mayans were able to easily complete exquisite crystal crafts, which amazed the world. It is said that their ancestors left 13 crystal skulls, and they can also talk and sing. The whole body is made of high-purity transparent crystal without any cutting marks. Sunlight refracts on the crystal skull, giving off a diamond-like light. The magical craft is difficult to conquer even modern high technology, so that more than a hundred years later, the mysterious crystal skull was recognized as a super precious cultural relic by the world.
