Does the broken wall belong to frozen soil?

The question you want to ask is whether breaking the wall belongs to breaking the ground? Breaking a wall is not breaking ground. Renovating the house and breaking the wall will not break the ground. The "breaking ground" in the solar calendar refers to the first digging with a hoe when building a house, mostly referring to villas. In the Gregorian calendar, breaking walls is called "building". The word "building" only refers to the renovation and repair of houses in the old yellow calendar, including decoration, maintenance or adjustment of geomantic omen. This answer is for reference only. Don't be blindly superstitious.
