It is successful to use geomantic omen to guide the determination of unmarked tomb sites on the ground. "Smell" means smell. Open the surface soil layer of the tomb, take a pinch of tomb soil and put it under your nose to smell it fiercely. From the smell of the soil, you can tell whether the tomb was stolen or not, and judge the age according to the color of the soil. "Asking" means stepping on the spot. Visit the local elderly as a fortune teller or geomancer, and get the information and orientation of the ancient tomb from the conversation. "Cutting" means finding the right direction of drilling. Generally speaking, Qin and Han tombs are excavated from the top of the tomb, while Ming and Qing tombs are relatively strong and must be entered from the back of the tomb.
