The "pyramid" belongs to the Hongshan Culture period of 5,000 to 6,000 years ago, according to Guo Dashun, a famous Chinese archaeologist who works in Liaoning Archaeological Research Institute.
Seven tombs and ruins of an altar were found on the top of the "pyramid." At the site of the altar there are many fragments of broken pottery carved with the Chinese character “mi" (rice).

Buddhism in Mongolia began with the Yuan emperors conversion to Tibetan Buddhism; however, the Mongols returned to their old shamanist ways after the collapse of their empire and it wasn't until the 16th and 17th centuries that Buddhism reemerged.
At the end of the 17th century, what is now Mongolia had been incorporated into the area ruled by the Manchu-led Qing dynasty.
Archaeologists said that the character "mi" may have something to do with people's understanding of astrology in ancient times.
In one of the tombs, archaeologists found a bone flute and a stone ring, and they unearthed a stone sculpture of a goddess the size of a human body in another tomb.
