After death, the monarchs of the Yuan Dynasty would load the bodies with empty wood, and then after burial, they would use Wan Ma Benteng's method. In the burial place, the land was leveled to avoid leaving traces. This is the way Genghis Khan used after his death, and then transported to the northwest, surrounded by barracks as protection, and the camp burial will not be evacuated until the next spring, so that outsiders can't see the dead buried here.
After Kublai Khan established the Yuan Dynasty, in order to learn Chinese culture, he changed the custom of tombs and used coffins, but the coffins of the two parts were combined and tied with iron sheets. However, the burial ceremony of nomadic people continued, and only the weapons used by the tomb owner were buried with wood. However, Han officials were not allowed to be present at the funeral of the Yuan emperor, and no buildings would be built on the ground.
In order to avoid disturbing the owner of the tomb in the future, ancient books rarely mention the place where the emperor was buried, so as to achieve the purpose of confidentiality. That's why his emperor's mausoleum is not near the capital. In fact, until now, we have not found the tomb of the emperor of the Yuan Dynasty. This simple burial method is also a great respect for the owner of the tomb. Compared with other dynasties, the momentum of burial is so great that we can understand. After all, it can go to another world with dignity and avoid the grave being visited by grave robbers.
