I can answer this question very simply. At that time, Sun Dianying stole the tombs of Cixi and Qianlong. After the treasure was stolen, most of the bones of Cixi remained intact in the tomb. There are six people buried in the tomb of Qianlong (including Qianlong), and their bones are scattered in the water in the tomb. The bones of one of the concubines are intact, except for the skull of Qianlong, all the others have been identified, and the rest are scattered in the tomb. After the incident, Qin Huang, a direct descendant of the Qing court, brought people back to join the coffin. Cixi was buried alone, and the bones scattered in Ganlong's tomb were finally put into the coffin because they were unrecognizable. So far, there has been no big change. The above materials (photos and written records) can be verified.
