Is the stone of the whole building good or three pieces?

Anything is ok, but the stone that has passed through the doorstone is better to be a whole piece. If you really need to divide, you must also remember that it can't be divided into two equal pieces. Because this is the middle seam of the threshold, which is not good for Feng Shui. Divide it into three parts, that is, divide it first and then take half of it. When paving, put the two small ones on the side and then put the long one in the middle. But if it is divided into three pieces, the overall effect is not as good as the whole piece.
