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

With Li Shimin speaking, Changsun Wuji could only agree although he was still a little worried.

"Prince Yan, then the next issue of the magazine will be located in Nanshi. After I go down, I will trouble the prince to introduce it to the minister."

Li You opened his mouth and was about to agree, but suddenly he had a new idea.

He smiled slightly and said: "If the eldest grandson really trusts me, then I will hand over all the magazines of this issue to me."

"I'm also very familiar with running magazines."

[This Nanshi has put a lot of effort into labor and management, and many things can't be announced until the opening day. 】

[Although the magazine manuscript this time is to build momentum for Nanshi, the method is quite different from the previous ones. 】

[If you write down all the selling points of Nanshi in this way, with the copycat speed of these aristocratic families this time, it is estimated that by the time Nanshi actually opens, they will be knockoffs already on their way! 】

【So, this time, we need to both publicize and keep it secret, so as to attract the attention of big businessmen across the country. 】

Thinking of this, looking at Changsun Wuji's embarrassed eyes, Li You was about to think of ways to persuade him, but he didn't expect that Li Shimin would start to attack again.

"Wuji, you were exhausted from the previous two episodes, so you should take a break. Since Yuer has boasted so much, let's sit and see how he can turn the situation around."

"If he can really change this situation, you can do a good job together in the sixth round."

With Li Shimin's words, Changsun Wuji had no choice but to agree.

He was really tired these few days, especially when Li Shimin postponed the marriage just now, which made him exhausted physically and mentally.

After some thought, Changsun Wuji nodded dejectedly and offered to resign.

Seeing that Changsun Wuji was about to slip away, Li You naturally proposed to go back to work.

However, after Li Shimin let Changsun Wuji leave, he stopped Li You.

Now he has a lot of questions in his mind that he wants to ask Li You.

Li Shimin was also very curious about Li You's method of not making it public but also attracting people's attention.

But in the end, Li Shimin asked a question that he was most concerned about: "You'er, you heard just now that I postponed Xiao Lizhi's marriage."

"You recommended the book "Health Care during Pregnancy" to the queen before, and you have done some research. I wonder when do you think it is the most suitable time to get married?"

Li You was surprised when Li Shimin suddenly asked this question, but he still replied subconsciously: "The best age for women to give birth is between 23 and 30 years old, so the best age for marriage is 22 years old."

"What, 22, isn't it a little too late?"

According to Li Shimin's original idea, he wanted to delay Xiao Lizhi's marriage to an age that Li You thought was appropriate.

But after hearing about Li You's age, Li Shimin was still not calm.

22 years old is really too late.

However, Li You did not consider Li Shimin's thoughts, but took advantage of his good mood today to popularize Li Shimin's science from a medical point of view.

"Studies have shown that mothers who are too young and not yet fully developed themselves will definitely have a negative impact on the development of their children."

"If you conceive before the age of 20, the fetus competes with the developing mother for nutrients, which is not good for the health of the mother and the development of the fetus."

What Li You said was so convincing, Li Shimin naturally believed it right away.

Immediately, Li Shimin said in embarrassment: "Your's words are also reasonable, but the current situation of Datang does not allow it."

Li Shimin is also talking about the national conditions.

After the great chaos at the end of the Sui Dynasty, the population of the entire Tang Dynasty dropped so badly that all walks of life were very depressed, and a lot of unowned land in the fields was abandoned.

Therefore, in order to make Datang prosperous, one of the things Li Shimin is trying to promote is to quickly restore the population.

For this reason, Li Shimin stipulated that women must marry before the age of sixteen. If they are not married by that time, both men and women will be punished.

And this penalty will continue to increase according to age.

With Li Shimin's financial resources, even the highest fine can be afforded for Xiao Lizhi to marry after the age of 20.

But if this spread, it would definitely be criticized by countless people.

Even if it is the voice of the people, Li Shimin can choose not to listen to it, but there are still admonishers like Wei Zheng in the court.

They will certainly not sit idly by this kind of thing that is contrary to national policy.

Of course, Li You also knew about Datang's need for population.

We must know that if the average child is born at the age of 15, three generations can be produced in 45 years, and if it is after the age of 20, this time will become 60 years.

Among them, the gap of 15 years is a difference of a whole generation.

Taking the current situation of Datang as an example, the importance of this generation can be reflected in many aspects.

Externally, it was the combat power of Datang to expand its territory, and internally, it was the creator of Datang's prosperity.

In Li Shimin's view, the importance of this generation is more important than one or two foreign victories.

For this reason, even if Xiao Lizhi was sacrificed, he could only bury the pain in his heart.

If it were at any other time, Li You might just sigh and leave silently.

But today, Li You was in a good mood, so he talked to Li Shimin with great interest.

"Father, in fact, there are many ways to solve the population problem."

"For example, farming. Now we have obtained a large number of cattle from the grassland. After taming them into farming cattle, the efficiency of farming is much higher than before."

"My minister has also heard the news from the Ministry of Household Affairs. This year's planting area has more than doubled compared to the early years of Zhenguan. All of this was done while the population did not change much."

The Tang Dynasty ruled the world basically four years after Wude, and it is only 11 years away from now. It belongs to the generation of Datang, and they are still children now.

Therefore, although the population has increased a lot in recent years, the labor force has not changed much. If it is not because of the many grassland slaves, it is estimated that the labor force in Datang will be scarce to a heinous situation.

Li Shimin is naturally aware of this situation, but agriculture is not the only place where people are needed.

"The problem of farming can be replaced by cattle for the time being, but what about the Ministry of Industry?"

"In the past few years, there have been many construction projects, and there will be more follow-up projects."

"Now that there are new crops, they can be planted all year round. Farmers are too busy to do things in the field, and basically use goods to replace corvee."

"If there is no population supplement, sooner or later there will be problems!"

However, facing Li Shimin's question, Li You smiled and asked back: "Father, do you know why my son never opposes launching a war?"
