In the evening of the same day.

A shanty town outside the city of Peiping.

The lit oil lamps make the simple houses look dim.

On the square table, there was a plate of peanuts, a plate of beans, a plate of winter melon broth, a plate of pickles, and several old men drinking wine.

In the distance of Beiping City, the eastern sky shows various colors.

The city that never sleeps.

The lights on the streets were much brighter than in the shantytown, not to mention the restaurants that looked like daytime.

In the river in the city, the cruise ships with lanterns flow slowly, and people come and go on both banks.

There are those who sing operas, those who sell all kinds of snacks, those who tell stories, those who play acrobatics, those who talk about the Three Kingdoms, and those who talk about new scripts.

There is also a stall where bamboo dragonflies fly into the sky and attract many children.

Pinch all kinds of mythological characters with sugar.

……

The government is becoming less and less, and the vitality of the people is getting stronger and stronger.

But there are still a lot of poor people in poor clothes on the streets.

In the past, the errand servants who served in the government not only needed to bring their own dry food, but also had to work for free, but now they have a subsidy.

Those long-term errands are naturally different, and their positions are not available to ordinary people, but more ordinary errands are painful.

Now that they have money to earn, they don't feel troubled by patrolling the streets.

However, the bustle in the city only belongs to a small number of people.

People in shantytowns are mostly busy for survival, and they don't have time to go to the city to play on weekdays, only during festivals, they will go to the city to spend money on the whole family.

"You've really decided not to go into the water?"

Xiashui Village was originally a very ordinary village.

If there is a village in Xiashui, there must be a village in Shangshui, because it is the route of the Daxing and Beiping railways, and it has become the area where the group building houses are located.

Several of the group building areas are in similar areas.

"It's been decided, I'll go to someone else's workshop tomorrow to work." The old man said.

Their conversation has a Shandong accent.

"We are all from the same place, why don't you discuss such a big matter with us."

"What is there to discuss, I see, you should join other people's workshops as soon as possible."

"I don't go, I eat with my own skills, why do I have to work as a long-term worker with others, and earn more than others."

"Although there is a lot of work here, there will always be a day when it will be done, and I will go back to my hometown at that time."

The old man shook his head.

"When you're done here, let's go to the next place, is there still a shortage of work in Beiping?"

"My kid went to school, and I didn't want to run around, and my mother-in-law also wanted to stabilize and didn't want to live the old days."

There was an influx of people from other places.

Some of these people are skilled people, such as this group, who are traditional carpenters who make furniture for the common people.

The development of the construction industry in Beiping has driven many industries.

These carpenters, who did not work in their hometowns, became sought-after, not only by the common people, but also by many decoration companies.

Faced with different choices, some people go it alone, and some people choose to join.

There is no good or bad.

As long as the social and economic development continues to advance, they can live according to their own desires and there is no conflict.

Choose.

It is often said that the ancient system limited the population to the land.

But in an agrarian society, what can people do without the land?

They simply don't have a choice, and they don't have countless factories to provide them with.

They don't have the capital, vision, or network to do business.

There is only one reason to leave the land, to survive.

Whether it was the earliest Hui merchants, or the sea people who went to sea in Fujian, or the landless displaced people, they first left the land to survive.

So people love the land.

Because the land is what keeps them alive.

The next morning.

On the way to school, the kid from this family came together with a few classmates, and a few people talked and laughed, and seemed very happy.

His father went to work in someone else's company, and because of his good craftsmanship, he was paid a tael of silver a month.

School reading is free.

Without the pressure of survival, the teenager was in a semi-closed environment like school, and the new social life pattern changed him in just a few months.

From words to deeds, there is a slight change.

The more time he spends in school, the more this change will be.

This is the group that is most prone to change, because it is a blank slate.

There was a newspaper seller outside the school, and the young man glanced at the newsstand nostalgically, remembering when he walked the streets and alleys to sell newspapers.

"Jingle bells."

The school bell rings.

The recent graduates of the school are all recruited by China Heavy Industries and marked as reserve talent cadre savings.

This label alone has attracted more people to send their children to school.

Study and become an official.

Most ordinary people don't dare to think so, and they don't have this luxury.

But if you can enter China Heavy Industry by studying, and even become a steward, it is full of temptation for the people.

And this premise is that the common people have a stable life.

Fortunately, the per capita income in Peking has steadily increased, and the schools are free of tuition, and some even have free meals.

Then many families who left the land to enter the factory, and the children who did not need to join the land labor, became redundant.

The changes in various circumstances have made the people of Peking happy to send their children to school.

This is different from the common people who farm the land.

Because the common people who farm the land, even if they are children, can be regarded as half of the labor force, and they need to work on the land.

With the rise of schools, the demand for teachers has increased.

The old literati at the bottom were hired, which also gained benefits, and weakened the discourse power of the traditional landlord class.

"The registration for the teacher exam will stop next month, and if you need to take the exam, hurry up and register, it will be too late after the deadline."

Teacher's Office.

Someone came in to inform.

An old man in a long robe pinched his desk and hesitated.

"Did you sign up?"

"Nope." The old man said writhingly.

"You haven't decided yet?"

The colleague looked at the stubborn old man in wonder.

"The content of the assessment is too vulgar, Sven sweeps the floor, what kind of thing is it." The old man said unhappily.

"You can think clearly, if you don't pass the exam, you can only teach the lower grades, and there is no level and corresponding benefits."

"Wealth can't be lewd, the old man doesn't care."

The old man straightened his waist and said.

Hearing the old man's words, the man couldn't help but smile.

Joining the school as a gentleman, the salary is very high, and the lowest level is one or two or five dollars a month, which is fifty percent higher than the salary of ordinary workers in China Heavy Industry.

There are four levels of Mr. Teaching.

Elementary, Intermediate, Senior, Extra-Senior.

Corresponding professors to students of different ages.

In people's minds, it is natural that the more senior the professor, the more famous the student.

It's the same as Kedao.

Who has mentioned Mr. Enlightenment, the later Mr. is the more important.

"I've heard that the more you go on, the more difficult it will be to take the exam, and the grade will be more detailed, if you don't hurry up the exam now, I'm afraid that you will fall behind in the future, and it will be more difficult to chase the level."

"Think about it, you will also walk out of the school gate in the future, others are super senior gentlemen, you are the junior gentleman, and you have no face."

When it came to face, the old man couldn't help it.

"Think again, old man."

The old man said.

After school in the afternoon, the old man returned home, and finally couldn't help but pick up the newly compiled textbook, looked at it with disdain, and was about to throw it away, but finally opened it.

Etiquette, music, archery, royalty, calligraphy, and mathematics six subjects.

Shooting and royal are related to military affairs.

The school's archery and imperial subjects teach archery lessons, riding lessons, orthopedic lessons, firearms lessons, etc., and are mainly outdoors-based courses.

Etiquette is a moral education lesson.

Music includes music courses such as the 12 equal temperaments.

Books are the liberal arts of literacy and writing.

Mathematics is the science of science, mathematics, technology, etc.

The school is not pursuing the imperial examination, but also developing in all aspects, as long as the people are willing to send their children to the school, it will be considered a success.

With the slogan of guaranteed employment and free tuition, many people are happy to send their children.

The content of school textbooks mainly contains the book knowledge of the ancestors, as well as the things developed by China Heavy Industries, such as the theory of the steam engine.

Generally speaking, it is not deviant, it is just to eliminate those vulgar knowledge, such as cutting meat to save the mother.

Day 2.

The old man hesitated, but finally mustered up the courage to hand in the application form, passed by the senior classroom, and heard the voices inside.

The old man looked curious.

I saw a picture drawn with chalk on the blackboard.

The first row is a circle, and two lines are drawn below the circle, connecting the two circles, and two circles in the second row, and two lines are drawn under each circle.

For the inner line, the two circles are connected to the circle of the next layer, and the outer line is connected to a circle separately, so that the third layer is three circles.

And so on, and there are nine circles in the ninth row.

In each circle, it is marked with the ancient simple numerical record method of one, two, three, (four) and T (six).

"You can see this picture, it is the ancestor Zhu Shijie, after the fall of the Southern Song Dynasty, as a mathematician, he traveled around the south for more than 20 years."

"Comprehensively inheriting the mathematical achievements of the ancestors and preserving the treasures of Chinese civilization, it is one of the few existing complete knowledge systems."

"It not only absorbs the Tianyuan technique of the north, but also absorbs the positive and negative prescription techniques of the south, various daily algorithms and popular songs, and on this basis, one of the results of creative research is carried out."

Pointing to a piece in the picture.

The young teacher on the podium said skillfully.

"Here is the left is the product number, the right is the corner of the calculation, the Tibetan are cheap, can be described as a triangular structure, to the cheap multiplication of the business, the fate of the real and divided, is the role of each coefficient in the establishment of the lock release method."

If according to the later generations.

The right side is the corner calculation, which means that the top-down "1111111" on the right side is the highest sub-term coefficient in the expansion formula;

The right corner is not a mathematical term, (a+b)^3=a+3ab+3ab+b is the cube, and the 1 on the right side represents the highest subterm, b^3 (a^3), and the coefficient is 1.

……

"This lesson is very important, and only when you understand it thoroughly, can you keep up with the progress of the high-order equal-difference series summation formula and the equal-spaced quadruple interpolation formula in the next stage of the quaternary elimination method."

Forty students in the classroom let out a lament.

Outside the window,

The old man looked at the blackboard closely, then shook his head helplessly and left.
