First of all, what is a zombie?
Zombies are a species in ancient legends of ghosts and gods in China. Zombie images on TV are usually born with resentment, blending the dead with the dead. The body will not rot for thousands of years, and the whole body will be stiff. They can only walk by jumping and feed on human blood, which is terrible.
Let's talk about the zombie legend again.
In historical legends, the earliest zombie was Hiderigami (the daughter of the Yellow Emperor). In order to retaliate against the heroic spirit of the Yellow Emperor and turn him into a zombie, Chiyou didn't suck human blood at first, but the atmosphere of heaven and earth was thin, and people had the atmosphere of everything, so he sucked blood.
According to folklore, the ancestors of zombies came from one of the four ancient gods. It is rumored that Nuwa and Fuxi sealed her soul and became the ancestors of zombies because she participated in the war between the Yellow Emperor and Chiyou. Most importantly, he combined with the branches of the holy tree to form a general. It is said that Nu Wa made people according to the general's appearance, so zombies and people were the same at that time.
Because of these legends, in the long river of history, before the Qing Dynasty, zombies were actually not considered as bad species. They are considered as "dead bodies that don't rot", and they are considered lucky because the deceased had virtue and justice before his death. After the death of the emperor, in order to pursue a state close to his life, he would wear gold and jade clothes and be buried with yellow intestines. After the Qing Dynasty, some people made up some imaginative stories, such as Yuan Mei's "Wu Zi Yu", which said that in a place where yin and qi gathered, the dead would be resurrected to form zombies. In fact, this is completely nonsense.
What about the legend of ancient zombies? What is the basis?
After death, the body will certainly rot, but it can be preserved. The wet corpse of Mawangdui in China has been well preserved so far, and the research of modern anti-corrosion technology is changing with each passing day. But general anti-corrosion is only used for nobles, and ordinary people don't know it. Under the blessing of ancient feudal backward thoughts, some people saw the lifelike bodies of others and thought it was the resurrection of the dead and zombies.
In addition, the land where the body is buried may be frozen soil or dry soil without water. The activity of saprophytic bacteria was inhibited in low temperature and dry environment. There are also poisoning-dead, toxicity-inhibiting bacteria, so the body does not rot.
In a word, it is normal for the corpse not to rot, which has nothing to do with zombies.
The medical level in ancient times was limited, including shock, severe coma and suspended animation. Usually considered dead, the ancients thought they were dead. In addition, it stopped for a long time, so there may be cases where some people are moved into coffins before they die. Then these people wake up briefly, and they can't avoid moving their postures or even pushing coffins. Outsiders found a noise in the coffin, or opened the coffin many years later and found that the body was not what it looked like when it was buried. They thought there were zombies in horror.
After disembarking, the body will rot normally, and the internal organs will rot the fastest, producing a lot of gas, which will break through the body and emit it to a certain extent, similar to fart. If the coffin is being sacrificed, the buried person will hear it, the voice will vibrate, and he will be scared to death and think he is a zombie. At that time, rabies was prevalent, and sick people were afraid of light, so they stayed up all day and went out at night, which looked strange. They bite everyone, that's why zombies eat people.
To sum up, we know that there were no zombies in ancient times, and we don't have to be afraid. The zombies imagined in those novels and movies don't exist.
