The Chinese people have always had the saying of "many children and many blessings" and "two children and two complete children", believing that the reproduction and prosperity of children and grandchildren is the fortunate thing of the family, and it can strengthen the ethnic group and shine on the lintel.
However, the twins that modern people are very envious of, including the dragon and phoenix fetus, were not very "popular" in ancient times, especially for the royal family, which was even more taboo.
How did the twins form? It is divided into identical twins and allombiontic twins
The probability of conceiving twins naturally is about five in a thousand, and the probability of a dragon and phoenix fetus is one in a thousand.
Twins are divided into two kinds of fraternal twins and identical twins, first of all, identical twins, when the sperm and egg are combined, the fertilized eggs are divided into two when they take root and sprout in the womb, thus forming two embryos.
These two embryos carry the same genetic material, so after birth, all aspects are very similar, the appearance is needless to say, the personality, hobbies are very close, I have to sigh the magic of the Creator!
Fraternal twins are two sperm and two eggs combined separately, each developing into an independent embryo, they have their own placenta, and the genetic material they carry is not the same, so after birth, they are very different from identical twins.
Why was the probability of twins in ancient life low? The reasons behind this are complex
To be fair, there are very few records of this in ancient times, and it is difficult for ordinary people to have children, let alone specific statistics, so we do not know much. Only some examples can be found in ancient poems or royal records.
Li Qingzhao once wrote a poem to celebrate the birth of a pair of twins at a relative's house, "Jade carved double Zhang, brocade pick pairs of clothes".
From a medical point of view, people living in ancient times generally married early and had children early, and women before the age of 20 had already had a large number of children. Premature pregnancy is not easy to give birth to twins, when the mother is still long, it is easy for mothers and babies to compete for nutrition after pregnancy, and "soil" is not suitable for sowing two seeds at the same time.
Life is very magical, the future baby will take the initiative to avoid harm, or originally pregnant with twins, and later "disappeared" when they grew up in the abdomen is not known, after all, there was no B ultrasound in that era.
In contrast, modern people, medical technology means developed, through the promotion of drainage, test tubes and other technologies, not to mention the twins, men and women can be predicted in advance, can not be the same day.
Is it more fertile to have "twins"? The ancients did not think so, and the limitation of medical conditions was the main reason
Giving birth to twins or dragons and phoenixes is "double happiness in the eyes of modern people", but ancient people often held the opposite view, and the reasons are very realistic.
1) Medical technology is underdeveloped, and the risk factor of having twins is high
The development of ancient medical technology is lagging behind, and it is not easy to give birth to a child with the help of an experienced midwife, let alone give birth to two children? This will greatly increase the probability of difficult childbirth, and even the mother and baby are damaged, so it is regarded as an ominous omen by the ancients.
2) Lack of understanding of maternal knowledge and regarded as a "vision"
The ancients did not understand the principle of the formation of twins, this phenomenon is also relatively rare, the mother will bear great pain and risk, at that time there was no caesarean section of the technology, can not be born, can survive a few all rely on "Providence", so it is regarded as a vision.
If the mother dies because of this, the child will be considered to be a "mother" and a "twin debt collector", which is actually caused by a lack of scientific understanding. Under that historical condition, it is also understandable.
The royal family is particularly taboo about concubines giving birth to "twins", after all, it involves the succession to the throne
There are very few records of twins born to the royal family in history, and there are two more famous records, one is recorded in the Book of Northern Qi, "Empress Lou of Qi Wuming, twin a man and a woman", is a dragon and phoenix fetus.
On the other hand, Zhu Zhanyuan, the King of Zhao of the Ming Dynasty, gave birth to twin sons, and Ming Yingzong was very happy, writing a letter to He Xi to "inherit the birth of two sons in the palace of uncle." This gai ancestor Fu Yu and ..."
He believed that this was the income of the ancestors' protection and the blessing of King Zhao, who should be well raised and procreated.
Looking at these two articles, one is a dragon and phoenix fetus, the girl has no inheritance rights, so it is generous to "officially declare"; the other is for Wang Ye Tian Ding, farther away from the throne, so everyone is also happy to hear and be very happy.
However, in ancient times, the royal family was actually very taboo about concubines giving birth to twins, and the birth time of two children was too close, which was easy to cause the second eldest to "covet the throne", after all, compared with others, he was only a little bit worse.
In order to avoid the hidden dangers of twins competing for storage, there is a saying that "twin emperors, one son goes to one son", in order to ensure that the country and the mountains are forever solid.
But this is only a legend, the secret of the royal family is little known, but this anxiety is definitely there.
