In order to be able to learn practical skills, they honestly sit on small benches and listen carefully.

Some people were literate and wrote down the Master's words on paper.

Some people are illiterate, so they can only watch attentively, listen carefully, and remember as much as they can.

If you don't, wait until after class and ask your classmates or masters.

After watching here for a while, the eldest prince came out.

Now it's time for arithmetic class.

Those who need to learn arithmetic come to the arithmetic class.

At this time, there was enlightenment arithmetic and practical arithmetic.

The eldest prince didn't study, so he followed the second prince directly to the enlightenment arithmetic and sat in the empty seat at the back.

This is just a school entry this summer.

Students have learned about numbers, as well as number combinations, and now start adding and subtracting.

It's also simple at first, adding one and two digits and subtracting them.

With the vertical type, it is easy to calculate.

Very friendly for beginners.

The eldest prince used this method to start using vertical calculations, but in fact, large numbers can be easily added up.

The second prince had been in contact with it before, so he wasn't curious.

After taking an arithmetic class, the eldest prince was still unsatisfied and began to continue to study the latter.

In fact, these mathematical knowledge were copied by Liu Paner from the mathematics books of the nine-year compulsory education.

The eldest prince began to study on his own, and when he met something he didn't understand, he asked his younger brother.

The second prince won't, so he came to ask Li Dabao.

Li Dabao saw that the eldest prince studied seriously, so he naturally spoke very seriously.

So much so that the eldest prince studied too seriously and studied until late at night.

If it weren't for the chamberlain around him, he tried his best to dissuade him and let the eldest prince rest early, it is estimated that the eldest prince would be able to study overnight.

These elementary maths were so simple and easy to understand that the Great Prince was able to teach himself.

The further you go, the harder it gets, and sometimes it takes a little more time.

The second prince saw that his eldest brother had been studying mathematics in the study, and he couldn't cry or laugh.

"Big brother, this mathematical knowledge can't run in the books, and you will slowly ponder it when you return to the capital."

"Shouldn't you walk around and look around? In this way, you can understand the people's feelings, what have you been understanding in the house? ”

When the eldest prince heard this, he was slightly stunned, "Fortunately, you reminded me that if I continue to watch, I will indeed waste this good opportunity to go out of the palace for a private visit." ”

"It was meant to be!" The second prince smiled, "Let's hurry up and walk around!" ”

After the persuasion of the second prince, the eldest prince put down the math book in his hand, walked around, and took a look.

Wearing a straw hat, walking in the fields.

Li Dabao also took the eldest prince and the second prince to the field, pulled weeds, and stepped barefoot in the rice field.

The second prince finally pulled out a weed, his body staggered, and he almost fell.

At this moment, there were actually a few small fish swimming by the surface of the feet.

"Oh, there are still fish in the rice fields!" The second prince exclaimed, and after stabilizing his body, he was about to catch fish.

Li Dabao smiled, "That's the rice flower fish, caught some fish fry and put them in it." ”

"When the rice is almost ripe, the fish will grow to the size of a palm. Whether it's a fresh fish stew, braised fish, or salted fish, it's delicious. ”

"It's just that it's too small now, and I don't know how to eat it if I catch it."

The second prince was a little disappointed, but he saw that the little fish had swam away, and he couldn't catch up with him at his speed.

"When is the harvest? Can we still eat the fish before we return to Beijing? The second prince asked, staring at the small fish swimming around in the rice fields.

Li Dabao replied: "It'll be fine in a few months, don't worry, you should be able to eat." ”

The eldest prince has always been calm, and he also saw the small fish, but he didn't think about eating it, and was carefully observing.

"Dabao, these fish eat rice flowers, as well as insects in the field, and the manure they excrete can fertilize the field."

Li Dabao was surprised, "The eldest prince is right, it is indeed beneficial to put some fish in the rice field." ”

The eldest prince smiled and asked, "Is this something that Mrs. Drey came up with?" ”

Li Dabao shook his head, "This is not what my mother came up with." In fact, there is plenty of water in the south, and most of them are paddy fields. ”

"When the farmer brings water, small fry come down the ditch to the farm. Some people in the local area have found that small fish can eat insects and can also fertilize the fields, so they will more or less put some fish fry in the fields. ”

"There is no need for much, too much, there is not so much food in the rice fields, and there is not too much water here, just a small amount of seedlings."

The eldest prince smiled: "It's good, I can farm and raise fish." It is no wonder that the south is relatively rich in products and wealthy. ”

Li Dabao smiled and explained to the eldest prince again, "Compared with the plains in the north, there are many mountains and rivers in the south, and in the past, this was all wasteland and a land of poisonous miasma. ”

"It is precisely because some people have come here to develop the development zone that there is the current situation step by step, and further south, there is still a lot of land reclaimed by the people who fled before."

"A lot of it was because of war, some because of famine, and some because of a variety of reasons. The economy of the Great Zhou Dynasty was constantly moving south. ”

The eldest prince thought of the migration plan promoted by his father, there were many people in the Central Plains, and there was not much land, and many lands were seriously annexed.

The common people have little property, and if there is a slight disaster, they have to sell their fields to tide over the difficulties.

More and more land is in the hands of a few, and the proletarian people either work for others or sell themselves into slavery.

Many people do not have a good life in the local area, let alone development.

It's not the same if you can move elsewhere.

North and northwest, the south is vast and sparsely populated.

There's a lot of land development in the south, so why not move these people there?

After the experiment in the Northwest City, good results have been achieved.

This time, hundreds of thousands of people moved over to Beiyun City, and they gradually achieved results. The northern border is clearing more and more land.

Not only self-sufficient, surplus food, but also to feed hundreds of thousands of troops at the border gates.

After a day's work outside, the skin of the eldest prince and the second prince, with fine skin and tender flesh, was tanned.

The ninth princess was not worried about the eldest prince and the second prince, and she couldn't stay at home, so she dragged her family to Jixiang Town.

There is a newly built house in Jixiang Town, and a few sets are directly packed up and given to the Ninth Princess and Gu Shao to live in.

At this time, the ninth princess was talking to Liu Pan'er when she saw two red-faced nephews walking in from outside.

"Hey, why don't you wear a straw hat when you go out? You see that this face is tanned, if I return to the capital, I will not be able to explain it to the imperial brother and sister-in-law! ”

The eldest prince stepped forward to salute, "Auntie, you don't have to be like this. Since we are here to observe the people's feelings, it is natural that we want to experience the life of farmers. ”

The second prince also nodded, "Yes, auntie, don't worry." Only through personal experience can we know the hardships of farmers. ”
