First, the mausoleum of Qin Shihuang has organs.
Qin Shihuang, as a strict king, must have thought that someone would come to rob the tomb when he was building it. In order to prevent the tomb from being killed after his death, Qin Shihuang had already found someone to design an organ in the tomb. After Qin Shihuang's death, the funerary objects in his mausoleum were very rich, which certainly attracted many people's attention, but because of the organs in the tomb of Qin Shihuang, no one dared to go in. Once you touch the organ in the imperial tomb, you may end up dead here. Moreover, there is a lot of mercury in the mausoleum of Qin Shihuang, which is highly toxic. Many people are afraid to enter the imperial tomb because of this, so for so many years, the interior of Qin Shihuang's mausoleum is still intact.
Second, the geomantic theory of Qin Shihuang's mausoleum.
When Qin Shihuang built the mausoleum of Qin Shihuang, he must have visited people who looked at Feng Shui, because the ancients paid more attention to Feng Shui and thought that good Feng Shui was beneficial to themselves and even future generations. So in order to create a good feng shui, Qin Shihuang cut five rivers around Mount Li, which is equivalent to dragon claws, and this Mount Li became a dragon. From the satellite cloud picture, the mausoleum of the First Qin Emperor was built on longan, so archaeologists dare not touch the geomantic omen here at will.
Third, the regulations do not allow arbitrary excavation.
There are regulations in the Cultural Relics Bureau that it is forbidden to dig the king's mausoleum at will for fear that the cultural relics in the mausoleum will be destroyed. These cultural relics have been buried for a long time, and some of them have certain protection measures. Once the tomb is excavated at will, there may be some unknown dangers in the tomb, and no one knows whether the cultural relics will be destroyed after the tomb is opened. Once the cultural relics are destroyed, it is very likely that they will eventually be damaged because they are not properly protected. Therefore, before technology can ensure the absolute safety of cultural relics, the Cultural Relics Bureau does not agree with archaeologists to dig tombs.
