During the ten years of catastrophes, personnel were devolved, institutions were withdrawn, research was interrupted, data was lost, and at the time the propaganda “doesn’t get through”. Hollow bricks were finally killed in the cradle. Later, because the funds were not implemented, the construction contractor contracted and the designers were not accustomed to it.
