The round box next to the ancient corpse contains his brain, and the rectangular box contains his internal organs. Research shows that there are three main reasons why the ancient corpse did not decay for a long time: first, it was buried deeply, and the grave pit of the ancient corpse was about 10 meters above the ground; second, it was sealed, and there was a very sticky green material around the coffin chamber in his tomb pit. There is about 5.4 meters of dust mud and white plaster mud, and his inner and outer coffins are all sealed with linen and raw lacquer. This puts the ancient corpse in a stable environment of hypoxia, constant temperature and humidity for a long time; thirdly, the coffin liquid is antibacterial and Sterilizing and antiseptic effects.
