1. The shape of the bluestone should be regular: whether it is carved into handicrafts, plaques or directly used as building materials, it is necessary to ensure that the shape of the bluestone is complete and standardized, and there should be no abrupt protrusions or depressions, multiple corners or missing corners, which is beneficial to the feng shui at home.
2. Bluestone should have no edges and corners: when we carve bluestone into handicrafts or polish it into building materials, it is best to polish all the edges and corners 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.
3. The size of bluestone should be appropriate: it is necessary to ensure that the ratio of bluestone size to space size is appropriate. Bluestone is a natural stone. According to geomantic omen, bluestone bears a part of Yin Qi, so if the volume of bluestone is too large, it will lead to excessive accumulation of Yin Qi in the space, which is not conducive to home geomantic omen.
It should be noted that in Feng Shui, there is no absolutely correct conclusion, so different people will have different views and judgments on whether bluestone should be buried under the house. The final decision needs to be made according to the individual's specific circumstances and beliefs.
