If the celestial burial fails, it is necessary to bury the body in the water, that is, to sink the body into the water and let the fish eat it (in the past, Tibetan customs did not eat fish);
After the introduction of Buddhism, there was cremation, but it was rarely used because of the lack of fuel.
The nine-story demon tower is the No.1 tomb of Wei Xue discovered in China in 1996. It is the most spectacular of the Tubo ancient tombs in Dulan, Qinghai. The director of the tomb should be a member of the Tuyuhun royal family, so the level of the tomb is very high. It is located in Zamali Village, a hot water town on the Wei Xue prairie. Archaeological number is "Wei Xue No.1 Tomb", and the whole tomb is rammed (hung). The wooden floor is thin and short, thick and long, with a total of nine floors. In addition, there is an unlucky legend among Tibetans that this ancient tomb is a "high-rise building with monsters", so local farmers and herdsmen call it a "nine-story demon building". Tuguhun is closely related to the central dynasty and attaches great importance to learning the culture of the Central Plains, so tombs also pay attention to geomantic omen. The tomb is trapezoidal and double-walled. The north is connected with the natural mountain, and the south protrudes from the mountain. It is wide in the south and narrow in the north, with water on the back and facing south. There are mountains on both sides of the tomb that extend to the side of the tomb. There is a huge stone at the junction of two mountains, which looks like a bird's head. The mountains on both sides are muddy like wings, and the front looks like a Dapeng bird with wings to fly. According to the latest research data, the totem that Tuguhun worships is a sunbird, so this is a sunbird with wings that can fly. Right in front of the tomb is Chahan Wusu River, which is a treasure trove of geomantic omen! It shows that Tuguhun people believe in the theory of Yin and Yang Feng Shui in Han Dynasty, and this cemetery is a blessed land in Long Mai that Tuguhun people deliberately choose.
Dulan has a long history and is an ancient and mysterious land. In the long history of 3,000 years, Dulan was once the main pasture of the ancestors of Xiqiang, the main activity center of the Tuguhun Kingdom, which occupied an important position in the history of China, and the ruling place of the Tubo Dynasty. During the Song, Yuan, Ming and Qing Dynasties, it was also the neighboring area of western Mongolia after Heshuote entered Qinghai. The Tubo Kingdom has been trying to eliminate Tuyuhun.
This is the nine-story demon tower in reality. It is not mysterious in the novel, but it is the crystallization of the wisdom of the Chinese nation.
