Because this business has risks and benefits, the tombs of princes and princes are all in the mountains, and there are few people at ordinary times. It is the most profitable place for grave robbers. I don't know what these grave robbers in Shaanxi are doing. Maybe they are poor and crazy. They openly engage in such illegal activities in downtown areas. Maybe they think the most dangerous place is the safest. No matter how much camouflage there is, it can't escape the critical eyes of the masses. Plus the technology is so advanced now.
Speaking of grave robbery, don't think that TV programs, all kinds of high technology, are done with great fanfare. It's all TV plays. The real robbery is physical labor that increases life. When robbing a tomb, you should dig a hole first, not by machine, but by hand. It's extremely tiring, sometimes it can't be judged correctly, and it may even lead to landslides. At this time, there are almost no people inside. In addition, attention should be paid to sound insulation, and the soil dug out by stealing holes should be handled in time.
Perhaps this group of grave robbers were not careful enough when dealing with these problems, and then they were caught red-handed. You know, the key protected cultural relics are patrolled at any time, and there are cameras everywhere. It can be said that flies can't fly in.
