After long-term and continuous research by archaeologists, they finally found the answer. Studies show that these bamboo slips are not only not rotten, but also well preserved, because they have not been in contact with the air for a long time, that is, they have not been oxidized. When the owner of the mausoleum was buried, his inner hall and outer coffin were wrapped in layers and sealed with green mud paste, which isolated the air and prevented the air circulation in the coffin.

The ancients mastered a series of anti-corrosion techniques. Here, taking the anti-corruption of corpses as an example, some simple introductions are made. After death, in order to protect the body from decay, before the body is put into the coffin, others should bathe and change clothes. First, they should bathe their bodies with fragrant soup prepared in advance, and then scrub their bodies with wine. Bathing your body with wine and sleeping after cooking will play a role in disinfection and sterilization.

The spraying of wine is very beneficial to accelerate the consumption of oxygen in the coffin after sealing, and then establish anoxic conditions. This practice can inhibit the growth and mass reproduction of bacteria in a certain period of time, slow down or stop the initial decomposition process of the corpse, thus playing a role in preventing the corpse from rotting and preserving the corpse.

Putting some pepper spices in the coffin is also a good antiseptic method. Spices make the air fresh and make the human body emit charming fragrance. At the same time, pepper spices themselves can also play a role in antisepsis and sterilization. The smell of pepper and spices is very volatile, and the coffin filled with this smell can inhibit the activities of microorganisms in the coffin. In addition to these methods, there are some ingenious anti-corrosion techniques, and archaeology proves that the ancients were very wise. The same principle applies to the protection of other cultural relics.
