From the perspective of geomantic omen, in a short time, peers who have suffered from diseases and accidental deaths in a family have appeared one after another. That depends on whether there is any problem with the ancestral grave. 1, behind the graveyard plot, the mountain is uneven, with high sand and low sand. Then children tend to live short. No matter what the direction of the grave is, as long as there is a north-south road to the east of the grave, no matter the length of the road, if the road is small, the deceased will be injured by a car accident. This tomb is located at the highest peak of this mountain. Eight winds blow holes, four waters don't gather, and the water on the mountain head flows in all directions. It will also hurt men of the same age. 4. No matter where the grave faces, it is harmful if there are two depressions and a straight line (depressions include deep pits and rivers) within 30 meters on the left and right sides of the grave. This is called the wind with two shoulders, and the family is definitely a man. If there is no flat land in front of the tomb or the flat land is shorter than three or five meters, people who died prematurely due to accidents or diseases will die. 6. There are oblique flying roads in front of the grave, piercing the hall, breaking doors and stopping stones, all of which are short-lived, prone to illness and accidents.
