How to bury the geomantic omen in the cemetery (the turtle will go into the hole), on the head or on the turtle's back. No matter how you bury it, one thing is that the grave can't face the cave, let alone see the cave directly. According to modern geological considerations, the main caves are: 1, limestone geological caves. 2. Caves where volcanic magma flows and condenses. In the limestone geological area, there is no water and gas gushing from the surface, and there is no real dragon land. If the tortoise wants to enter the cave, it means that the tortoise looks good and reasonable, and it can only be buried in the other direction according to the Luantou Sect and the mountain situation.
