Datang: The prince of salted fish was overheard by Li Er

Hearing that it was an ancient book, Concubine Yin didn't think much about it, she put the book beside her and said, "You'er has a heart!"

Seeing Concubine Yin's casual look, Li You was also a little anxious.

You must know that pregnancy is a big event for a woman in this era, and once she is faced with having a child, she has already put one foot into hell.very dangerous.

Although it is normal for a family to have three or four brothers, or even seven or eight children in this era, the mortality rate of pregnant women exceeds 30.00%.

In the Tang Dynasty, a woman will get married when she is [-] or [-] years old, and she will get pregnant six months to a year after getting married. At that time, it is puberty, and the baby will steal the nutrition of the pregnant woman in the body.

Therefore, vaginal lacerations and postpartum hemorrhage are prone to occur during childbirth, so the mortality rates of both mothers and children are high.

And because there is no B-ultrasound and other detection tools, there is no way to know ectopic pregnancy, fetal malformation, etc. in advance, and can only be known at the time of delivery, but it is already too late.

In many cases, when a pregnant woman is bleeding profusely, she cannot stop the bleeding, and can only watch the pregnant woman die.

In addition, the environmental sanitation during childbirth in ancient times was not good, and there were no disinfection measures, so pregnant women were easily infected with diseases during childbirth.

This is why many women remain weak after giving birth to their first child.

Although Concubine Yin has better conditions in the palace and has a second child, Li You is still very worried.

And his "Health Care During Pregnancy" includes various aspects of hygiene, nutrition, psychology, etc., and also wrote some prenatal diagnosis methods for fetal abnormalities.

Although this book does not say that it can reduce the mortality rate [-]%, it can effectively protect the health of mothers and babies and improve the quality of births.

For this reason, Li You emphasized again: "Concubine Mu, this book is very useful, please don't take it seriously!"

"Okay, okay, okay. Everything is up to you, and I'll watch it slowly after you leave."

Sensing Li You's relationship, Concubine Yin's heart also warmed up.

Li You had just talked with Concubine Mu for a while, but Xiao Ying ran over in a hurry.

"Your Majesty, Your Majesty has come out of the study and is talking to General Li!"

Xiao Ying entered the palace with Li You before, and Li You was forced to go to Li Shimin's study, but Xiao Ying could not enter such an important place as the study.

So Xiao Ying has been waiting not far from the imperial study, and after Li You escaped through the window, she soon saw Xiao Ying.

Considering that Li Shimin would definitely know the news of his visit after discussing the matter, Li You left Xiaoying there and continued to serve as his eyeliner.

After hearing Xiao Ying's report, Li You didn't stay long and left the palace immediately.

"This child, that's your father, why do you want to see the creditor!"

Seeing Li You's leaving figure, Concubine Yin sighed for a while.

Sakura's return made Concubine Yin think that Li Shimin was coming back to her, so she hurriedly made some preparations.

Unexpectedly, Li Shimin did not wait, but instead waited for Empress Changsun.

When Empress Changsun learned that her illness was cured by Li You, she was very concerned about Li You's affairs.

After learning that Concubine Yin was pregnant, she often sent some supplements over.

But this time, Empress Changsun came to find Concubine Yin for another reason.

Empress Changsun is also pregnant.

If Li You knew about this, he would definitely scold Li Shimin as an LSP again in his heart.

But at this time, Li You had already left the palace like a rabbit.

Even though she knew it wasn't Li Shimin's visit, Concubine Yin had a trace of disappointment on her face, but after all, Empress Changsun treated her well, and Concubine Yin greeted her with a smile.

"Sister Yinfei, don't be too polite, we are all family."

Seeing Concubine Yin came out to greet her, Empress Changsun was as amiable as ever.

After the two entered the room, Empress Changsun took the initiative to talk about her pregnancy, which shocked Concubine Yin.

In fact, Empress Changsun came here today to look for Li You.

At the same time that Li You entered Concubine Yin's palace, someone also told the news to Empress Changsun.

Empress Changsun came to Li You just to ask if her illness would affect the fetus in her womb.

Now that Li You is not around, Empress Changsun told Concubine Yin about the matter.

Concubine Yin was also taken aback, she never expected that Empress Changsun would value Li You so much.

For a moment, Concubine Yin couldn't help thinking of the book "Health Care during Pregnancy" brought by Li You just now.

She remembered that Li You seemed to have mentioned just now that if there are certain characteristics in the body, then this child should not be born.

Immediately, Concubine Yin took out the book.

"Queen, I will definitely ask Youer about your affairs. Here is a book brought by Youer. Perhaps the Queen's situation is in the book."

As soon as she heard that the book was brought by Li You, Empress Changsun immediately became interested.

Due to illness, Empress Changsun and Li Shimin spent a lot of time together recently.

During the conversation between the two, Empress Changsun could clearly feel that Li Shimin attached great importance to Li You.

For this reason, she also developed a strong sense of crisis, and even sent someone to supervise the prince's daily behavior.

Back in her bedroom, Empress Changsun immediately flipped through the book "Health Care During Pregnancy".

At a glance, Empress Changsun was stunned.

Unlike Concubine Yin who has only one child, Empress Changsun already has three children, so she has more and deeper understanding of the difficulty of pregnancy.

The book begins with a description of the different periods of pregnancy and their characteristics.

Although I haven't talked about what to pay attention to specifically, such a precise segmentation has already shocked Empress Changsun.

"The king of Chu is really well-read and knowledgeable, and he was able to find such a powerful ancient book."

Empress Changsun read this book fascinatedly. It was not until the maid held the lamp that Empress Changsun realized that she had read it for two hours at a stretch.

"This book is really the gospel for women all over the world!"

As the mother of three children, Empress Changsun verified the things described in the book one by one on herself.

The final conclusions are exactly the same as those written in the book.

"If I could get this book earlier, I don't know how much pain I would have suffered!"

Empress Changsun was filled with emotion for a moment.

After closing the book, a bold idea appeared in the heart of Empress Changsun.

"I want to spread this book so that women all over the world will no longer worry about having children."

Thinking of this, Empress Changsun was also very excited. She felt that the time had come to realize her ideal.

Although she has managed the harem in an orderly manner since she became a queen, her reputation among the common people is also excellent.

But Empress Changsun knew that if it was just like this, the history books of later generations would only say that she mentioned it as a virtuous queen.

For this reason, Empress Changsun was very distressed. She didn't want to be taken lightly like this, and she also wanted to leave her own strong ink.

But she never thought of a way.

But when she read "Health During Pregnancy," she felt that this was her chance.

She understands that if the mortality rate of women is greatly reduced by relying on this book, then her name will surely go down in history and be appreciated by countless women in future generations.

Thinking of this, Empress Changsun couldn't sit still anymore, she stood up and shouted: "Come on, help me change my clothes, I'm going to see Your Majesty!"
