Eight white chambers
The scenic area's own introduction calls the place the Eight White Chambers: eight felt tents that could be moved. It says they were formed at the start of the 13th century, travelled north and south of the desert, and were settled in Ordos in the middle of the 15th century. In the early Qing they were moved to the Bayan Changhug grassland in Ejin Horo Banner. The architecture a visitor walks through was built in 1954. The tents and the concrete domes are not the same object.
A rite, listed in the first batch
The same page says the Genghis Khan rites are in the first batch of national intangible cultural heritage. That is a list of a practice: the calendar, the guardians, the objects brought out on the day. It is not a laboratory report on a grave. The page is the voice of the place that keeps the rite. It should be read as that.
What the page does not say
The introduction does not identify an excavated body, and it does not cite a World Heritage inscription. Those two sentences are the boundary of this article. Ordos has dunes, a new town and a coalfield as well. They are not this place. Here the thing to understand is a portable shrine that acquired a building, on a named grassland in Ejin Horo Banner.
