2. There are three ways to make future generations poor all their lives: one is "dustpan water", that is, Tang Mingshui is wide in front and narrow in the back; Second, there is no water flowing forward in front of the main hall. Even if there is water, it will not go straight to the distance and will not stop. Third, the tomb is on the hillside, and the surrounding mountains are higher than the peaks behind the tomb. There is no river in front, and the water flows in all directions.
3. The ancestral home faces the southeast, and the water flows from southwest to east, which can easily lead to rickets or people without legs, feet and arms, and even short life in severe cases. There are dead people in front of the tomb, and future generations will be incomplete, especially in the west, and there will be the possibility of inserting the door backwards.
