What was the name of fortune telling with the head of a chicken in ancient times?

Why did the ancients say that the head of a chicken is a game of arsenic for ten years?

Arsenic ten years ago. "Almost all rural people know this statement. Adults say children are not allowed to eat chicken heads. Our hometown says: "children eat the head of a chicken, and it will rain when they grow up." "

This sentence is still popular today, which shows that people are still jealous of the old chicken head. It is believed that chicken heads contain heavy metals or other toxins. If you are an old chicken for many years, the head of the chicken must have accumulated a lot of toxic substances, especially the comb. Think about lymph ... I'd better not eat it.

So, what about the arsenic in the ten-year competition?

First of all, there is no need to talk about the life span of chickens. This "decade" only describes the old chicken for many years, not a specific decade. Let's study the chicken head. ...

An old story about the head of a chicken. In ancient times, there was a family, a couple and a mother-in-law. One day, my mother-in-law died in an explosion at home, and later found out that she was poisoned.

Only the daughter-in-law and her mother-in-law were at home that day, and the daughter-in-law cooked for her mother-in-law. Poor and unlucky little wife ... got caught.

The daughter-in-law recalled: "My mother-in-law was in poor health. I stewed the only old hen in my family and gave her tonic. Nothing else was done. A piece of filial piety, but wronged me to death ... "

The government went home to collect evidence and found that the chicken head was poisonous. ...

The old hen really didn't want to be killed before. The daughter-in-law was so filial that she was almost wronged and poisoned her mother-in-law. Therefore, this matter spread to the ears of the subject.

This is a story that Bian Xiao read when he was a child. I don't remember the dynasty. Another version is the Song Dynasty, when the husband was poisoned. Anyway, it is enough to have such a story of an old chicken with a poisonous head.

Arsenic ten years ago? Really or not? "The fact is only one ..."

As mentioned earlier, "ten years" is an imaginary number, only used to describe an old chicken for many years. Don't talk about the age of chickens. It has existed since ancient times, not to mention the accumulation of toxins in chicken feed.

Common sense tells us that animal livers are detoxified, and if there are toxins, they will mainly accumulate on chicken livers. Science also shows that the toxins in chickens are accumulated in internal organs.

In other words, if the chicken ingests harmful substances such as heavy metals, the first problem is the liver, most of which are internal organs. Toxins will not enter the chicken head.

If the toxin enters the head, "the peripheral nerve is necrotic and the top is suppressed", won't the chicken head be suppressed more and more?
