If Xixia can predict that he can inherit the Nine Emperors, why not do something to change this fact and let the country he built perish instead? It doesn't make any sense. The imperial tomb of Xixia is a good place to study Xixia culture because of its integrity and large scale. It has also become a tourist attraction. Li Yuanhao established the Xixia Dynasty. After the establishment, he moved the graves of his grandfather and father to Helan Mountain, making their graves a member of Xixia tombs.
The nine mausoleums of Xixia Mausoleum, some were built in plain areas, and a few were built behind mountains. The layout of the Eight Diagrams and the Big Dipper was adopted in Xixia Tomb because it was influenced by Han nationality, Buddhism and Xixia's own Tangut culture. All these tombs face south and are uniform. At present, most of the Nine Mausoleums in Xixia Mausoleum can't match the Mausoleum of Emperor Xixia, and some emperors whose tombs are not in the Nine Mausoleums are likely to be hidden in the tombs buried with them.
Of course, there may be other places, or there may not be their own graves at all. In a word, since Xixia Tomb became a national key cultural relics protection unit, its internal secrets have been in a state of development. More secrets need time to tell us.
