The method of making mummies is very complicated. The first is the brain, which is wrapped in hard brain bones. The liquid cannot be taken out. Human decay is the first of these. The liquid goes bad first. So the ancient Egyptians would take it. The metal hook seeped out of the nose. Break through cartilage tissue and enter the brain. Mash the brain pulp, then let the head wash down, the brain pulp flows out of the nostrils and the brain is processed.
Then, the internal organs of the body. Mummification makes an opening from one side of the abdomen. Then enter the abdomen, take out all the internal organs except the kidney and heart, and bleed in the process. After taking out the internal organs and cleaning them. Will close any pores on their surfaces, wrap them in cloth and put them in a jar. Buried with the body. Don't think that the way ancient Egyptians treated corpses would be inhuman. In fact, they also took a fancy to the whole body.
It's just different from our concept now. They will recite the scriptures of the dead, deal with their internal organs and use incense. Cultivate a hollow body. It is troublesome to change it every few days. Then wash it and coat it with resin, which is time-consuming. You need to wrap your head, trunk, legs and arms, and then use bandages as a whole. There are many, many processes after that. It takes time, energy and money. So this is the mummy, I hope you can adopt my answer.
