3, bluestone should have no edges and corners: bluestone can be placed at home, but also pay attention to bluestone can not have edges and corners. When we carve bluestone into handicrafts or polish it into building materials, we'd better polish all angular places into circles, so as to prevent the edges and corners of bluestone from scratching people and ensure the health of our families. Secondly, it can prevent the edges and corners of bluestone from damaging the geomantic omen at home and ensure the stability of the geomantic fortune at home.
4. The size of bluestone should be appropriate: bluestone can be placed at home, but we still need to pay attention to the size of bluestone and ensure that the ratio of bluestone size to space size is appropriate. Bluestone is a natural stone. In geomantic omen, it is believed that bluestone has a part of yin, so if the volume of bluestone is too large, it will lead to too much yin in the space, which is not conducive to home feng shui.
