What organs did Wu Zetian install for his mausoleum? Why can't grave robbers get out when they go in?

Mainly because the dry mausoleum project is huge and built very firmly. According to the Book of the Old Tang Dynasty, the gate of Ganling is a stone gate, and darksteel is poured in the gap inside. According to the archaeological discovery of 1960, the dry tomb road is halfway up the hill in the southeast of Liangshan, and the tomb robbers of past dynasties have never found the entrance of the dry tomb road. Besides being strong, there are many legends about Ganling.

There are many sayings about Ganling. One is that Ganling is located on Liangshan Mountain at an altitude of 1047 meters in Ganxian County, Xianyang City. Besides, if it is on the mountain, the climate in the mountain area is changeable and the mountain is covered with rocks, which undoubtedly adds a lot of difficulty to the grave robbers.

Legend has it that in those days, Wu Zetian chose a geomantic treasure for her mausoleum. Yuan Tiangang, the warlock, was sent to tour the world first, and he chose a good place. When Yuan Tiangang arrived in Ganxian County, he found Liangshan, a treasure trove of geomantic omen, so he threw a copper coin as a mark. Later, Wu Zetian sent Li to find it, and Li also chose Liangshan, Ganxian County, and dropped a bronze nail. As a result, the copper nail was inserted in the square hole of the copper coin. Judging from this legend alone, Liangshan is indeed a treasure trove of geomantic omen.

The first person who stole Ganling was Huang Chao, the leader of the peasant uprising army in the late Tang Dynasty. Huang Chao's 400,000 troops almost razed Liangshan, but the entrance to the pyramid-shaped mound was not found, leaving only 40 meters deep? Huang Chao ditch? . The second basis is Wen Tao in the late Tang Dynasty. Wen Tao has rich experience in robbing tombs, and once stole 17 tombs of Tang emperors. But I missed in Ganling. It is said that during the grave robbery in Wen Tao, Ganling was tottering. When Wen Tao's army withdrew, Ganling immediately calmed down. Finally, Wen Tao also left. If Huang Chao and Wen Tao are in the age of cold weapons, their weapons are not advanced. However, during the Republic of China, the warlord Sun Lianzhong and his men failed to open Ganling with artillery and explosives. Even in the process of robbing a tomb, strange phenomena such as flying sand and stones and tornadoes appeared.

The real reason is that the building in Ganling is so strong that the entrance to the tomb has never been found.
