When the ancient Egyptians made mummies, the producers first sucked out the brain marrow through the nasal cavity and injected drugs to clean the brain. Then an incision is made in the abdomen, and organs such as lung, stomach and intestine are taken out, and the heart is left in the body. Then wash the body cavity with coconut wine and mashed spices, fill it with resin, linen impregnated with resin and sawdust, and sew it as it is.

The body should be completely buried in sodium oxide to dry. After 70 days, the producer took out the body, cleaned it, coated it with ointment and spices, wrapped it tightly with a lot of linen, and then coated it with resin. When dressing, start with fingers, toes, even limbs and the whole body. At the same time, special attention should be paid to prevent nails from falling off. The incision covering the abdomen symbolizes Horace's "perfect glasses". Mummies wrapped in this way maintain their shape before dehydration. Some mummies have a special mask on their heads, showing what the deceased looked like before his death.
