The nine-story demon tower was discovered in 1996 in the No.1 tomb of Wei Xue. It is the most spectacular tomb group in China, located in an ancient tomb group in Tubo, Dulan and Qinghai. The director of the mausoleum should be a member of the Gu Hun Dynasty, so the mausoleum has a high level. Located in the village of Zamari, Reshui Town, on the prairie of Xue Wei, the archaeological detection number is Da Tomb, No.1, Da Tomb, which penetrates and combines wood, concrete rammed earth wall and stone wall.
Wood floor, thin on the top and short on the bottom, thick on the bottom and long on the bottom, with nine floors. In addition, there are unlucky stories of Tibetans in this ancient tomb, which are considered to be high-rise buildings with monsters, so farmers and herdsmen in the field dismissed it as a nine-story demon building. Tuguhun attached great importance to learning Chinese because of his detailed contacts with the central government and the central dynasty. Accordingly, the mound is also highly regarded for geomantic omen. The tomb is trapezoidal double-layered soil, with natural branches in the north, branches sticking out in the south, long in the north and south, and facing the mountain in the north. There are mountains extending from both sides of the tomb to the side of the tomb. At the intersection of the two mountains, there is a huge stone, which looks like a bird's head.
The mountains on both sides are like the wings of a bird, and they look like Dapeng birds holding their arms in front. According to the latest research data, Tuyuhun's convincing painting method is locust warbler, a kingfisher spreading its wings and flying. In front of the tomb is Chahan Wusuli River, which is a treasure trove of geomantic omen. It proves that Tuyuhun people believe in the geomantic theory of birth, death, illness and death where they come from, and this mass grave is a paradise in Long Mai deliberately chosen by Tuyuhun people.
