According to the records of the Qing Dynasty Banknote Thief, these grave robbers can generally judge the location of the grave by listening to the wind, rain and thunder, or by the color and quality of the soil. More importantly, they can determine the location of the tomb according to the geomantic omen (after all, ancient tombs also depend on the right time and place, and cemeteries are more likely to appear in places with good geomantic omen). In this book, the method of determining the location of the tomb according to thunder is emphatically recorded. Because the bottom of the tomb is hollow, when there is thunder, the two will produce a * * * sound and a weak harmony, which provides an opportunity for grave robbers to judge their position.
Secondly, where there are graves, the soil color and soil quality will be different, which will affect the surrounding environment, such as the growth of tree roots, and the humidity and temperature of the surrounding environment will also change (where there are graves, the neighborhood will be warmer). Finally, the burial sites of cemeteries in different ages are different, and some families who have inherited the tomb robbery will accumulate these.
In short, grave robbery is the accumulation and inheritance of experience from generation to generation. Sometimes it can be made clear that it is not just a matter of "finding the dragon and dividing the gold into mountains", but a heavy entanglement is a heavy barrier. In the final analysis, it is illegal to rob a tomb, because it pays more attention to interests and lacks the study of cultural relics protection system.
