After the research of archaeologists, this ancient tomb similar to the "nine-story demon tower" belongs to Tuguhun's tomb. Because of the years of war between Tubo and Tuguhun, Tuguhun was called "the monster" by them. There are no mysterious creatures in the tombs, but there are a lot of cultural relics. All kinds of silks with fresh colors have been unearthed, and these silks still keep bright colors. The so-called saying that clothes are reduced to ashes and floating in the air is just a rumor and not credible.

The nine-story demon tower has a prototype, and this prototype is the "No.1 Tomb of Xuewei" discovered in Qinghai. "No.1 Tomb of Xuewei" was discovered in Chahawusu Town, dulan county, Qinghai Province on 1996. The tomb is 55 meters long from east to west, 37 meters long from north to south and 33 meters high. The tomb was left over from the Tang Dynasty. After the tomb is excavated, the inside is a real "nine-story demon tower". The inside of the tomb is a wooden tower cast with a large number of super giant trees as the skeleton, and the middle is made of masonry and mud structure. The tower is divided into nine floors, and the giant trees on each floor are engraved with mysterious ancient characters, which makes the "nine-story demon tower" even more rare. However, when the second floor was dug, the excavated cultural relics were very rich, and the cultural relics protection technology at that time was backward, and the tomb was very large. In order to prevent irreversible losses to the cultural relics below, the archaeological team and other relevant departments decided to stop digging this tomb. There were many such things, such as the Qin Shihuang Mausoleum, which also prohibited excavation.
