Why didn't anyone dare to steal Yong Zhengdi's mausoleum?

Yong Zhengdi's mausoleum is the Tailing Mausoleum, which is located in the Western Qing Mausoleum. Buried with Jiaqing, Daoguang and Guangxu. Grave robbers are all looking for money buried in graves. Yong Zhengdi told his courtiers not to be reburied after death, for the sake of peace after death and not wanting to be disturbed by others. The simpler the better, there are only a few gold and silver jewels in his tomb. Yongzheng didn't like spending money during the reign of Qianlong and Empress Dowager Cixi. After death, there were a lot of gold and silver jewelry in the tomb, which made grave robbers want to rob the tomb.

Yongzheng's tomb is very well protected, and there have always been defenders. Even after Empress Dowager Cixi abdicated, she signed "preferential conditions for clearing the scene" with the Nanjing Provisional Government, one of which was that the ancestral temple and mausoleum of the emperor must be protected, and a specially protected army should be established. Grave robbers, even if they are greedy for money, will not contact the army. After all, Luoyang shovel in their hands can't beat long guns and short guns.

? Yong Zhengdi's choice of the terrain of Tailing is also unique. The terrain here is complex, which makes grave robbers make unfounded judgments and determine the exact location of the twilight cave. There are many organs under the tomb, and they will die if they are not careful. Grave robbers dare not take risks for such a small amount of money.

Later, a stolen cave was found in 1980. Archaeologists believe that the Tailing underground palace may have been stolen. National Cultural Heritage Administration approved the excavation of Tailing Underground Palace. After careful inspection, it was found that the stolen hole was only dug two meters, so the archaeologists stopped digging the Tailing underground palace. Until now, it is still well preserved. ?
