Sitting in front of the window, Zhang Yue held his cheek and thought about his future.

On the windowsill, a bamboo and wood-carved calendar clearly shows today's date: Guimao (26th) in the summer, avoiding travel or marriage.

This calendar was made by Zhang Yue and the Tian brothers were then written on the date.

Because there is no paper, bamboo and wood are used instead.

The bamboo and wood are bulky and weigh more than a dozen kilograms on just one month's date, and are as thick as a cutting board.

However, this bulky calendar became very popular once it was launched.

Not only the scholars who came to Jiating, they all sought purchases.

Even the people in Jiating bought a pair back.

Can you know the daily life and the things that are taboo about auspiciousness? How strange! Who doesn’t like it?

And it's very cheap, just a pair of calendars cost ten yuan.

The people of Jiating can afford it now even the poor!

Because, now nearly two hundred scholars have gathered in Jiating.

People from each household can get as much as thirty or fifty dollars every day!

Today, Jiating has become a holy place for farm stays.

Young people from a distance of hundreds of miles gathered in this pavilion.

Whether the family is rich or poor.

Here, their status is equal.

Regardless of political inclinations, their pursuits are the same here.

Zhang Yue used books as bait and used some tips and tips from later generations to attract these more than 200 people here.

It not only changed his life.

It also changed the lives of the people in Jiating.

In just a few days, Zhang Yue's reputation has already left Changshui Township, and has gone to the entire Nanling County, and even radiated to Baling County, Hu County, Lantian County, and the capital.

Many people know that there is a Zhang Zizhong in Jiating.

He is generous and knowledgeable.

The most important thing is to share it with kindness!

Not only share books, but also reading tips and methods.

This is amazing!

It's simply a template for ancient sages!

And in this era, reputation is more valuable than gold!

Fame is even more important than official positions.

A good reputation and a reputation that can be spread locally are difficult to make.

But Zhang Yue no longer just wants to gain reputation now.

After the reputation is almost the same, as long as the status quo is maintained, it will gradually increase with the passage of time.

But no matter how high the reputation is, he is just a famous scholar.

If you have to endure it, you can make yourself live a good life.

As a time traveler, there is also space for this golden thigh.

Zhang Yue's ambition is now more than just making his own life better than his family.

He wants...

Change the world!

If you want to change the world, you must first influence the world.

In this world of BC, the best way to influence the world is to influence scholars.

As long as the scholars believe, the world will believe it.

A vivid example is right in front of Zhang Yue.

Thirty-six years ago, in the first year of Yuanguang, Dong Zhongshu wrote a letter today, submitting "Countermeasures for the Selection of Virtuous and Good", proposing the theory of great unification and the induction of man and nature.

So the world changed.

Confucianism is the only one who is the dominant Confucianism.

Even the law must be explained in accordance with Confucian classics.

However, Confucianism is the only one that can be achieved overnight.

It’s not that Dong Zhongshu is too awesome, but he has the spirit of a turtle when he writes a book. The world follows the scenery and the people bow their heads.

Instead, before the first year of Yuanguang, in the long history of more than seventy years.

The sages and giants of Confucianism work hard and overcome all obstacles.

From a ruin, I rebuilt my own moral, theory, knowledge and inheritance system.

Dong Zhongshu and Hu Wu were born in Guangchuan, and Linzi opened the mountain to receive disciples.

Shen Gong and Han Ying spread Confucianism in Chu and Zhao.

Other Confucian scholars, both of them, contributed to the prosperity of Confucianism.

The scholars of the Chu poetry school have traveled across the Mitsukoshi outside the border and even the southwestern barbarians.

Before the Han army entered these areas, Confucian scholars had already gone to the local area to explore.

The Confucian scholars of that era were like missionaries from later generations in the West.

They do not avoid difficulties and dangers, nor do they fear poisonous insects and beasts.

The torch is passed down from generation to generation, and the relay is to spread your thoughts and ideas to more places and let more people know!

In the 70th year of the rise of the Han Dynasty, Confucian scholars developed themselves from minority to majority.

By the first year of Yuanguang, at least seven out of ten scholars in the world were Confucian scholars.

Even if there are three left, they will be influenced by them.

Under such circumstances, if Confucianism cannot dominate public opinion and holds the right to speak, who can do it?

Therefore, it is not so much that Dong Zhongshu changed the world.

It would be better to say that Dong Zhongshu was standing above the trend of the times. What he did was just pushing it gently and opening the window.

The successful experience of Confucianism is right in front of you.

Zhang Yue knew that he wanted to realize his ambitions.

It also has to start with little things like Confucianism, starting with your feet.

Every time one more person is affected by him, he will change the world more.

So, what kind of knowledge can change the world?

The answer is...math.

As a time traveler, Zhang Yue knew very well that all technological and scientific progress in later generations were actually based on the establishment of mathematical progress.

From the nuclear weapons of the country to the smallest machine, everything is closely connected to mathematics.

The accuracy of every decimal point means a rapid advance in technology.

At this time, the social environment and public opinion also attached great importance to mathematics.

Among the six arts of Confucianism, mathematics exists.

In the national official system, there are special officials. The Han prime minister even once called him the prime minister!

The late famous officials, such as Zhang Tang and Er Kuan, were all powerful people in mathematics.

Erkuan even participated in the compilation of "Taichu Calendar".

This requires extremely advanced mathematical attainments. To be honest, even college students in later generations may not be able to participate in the compilation of "Taichu Calendar".

Naturally, it is very important to choose what kind of mathematical classics as the entry point.

Among the scriptures sent by the Imperial Academy is the immortal mathematical masterpiece "Nine Chapters of Arithmetic".

Zhang Yue has also seen it, and through Jin Yumu, he firmly solidifies it in his memory, and he can recite it backwards even with his eyes closed.

Therefore, he could almost understand the mathematical level of the Han Dynasty today.

It should be around the sixth grade of elementary school in later generations.

Chapter Nine Arithmetic has already involved the knowledge and application of solutions to multiple equations.

But the equation solutions used in the ancient "Nine Chapters of Arithmetic" are very complicated.

It is so complicated that it is difficult for ordinary people to understand and understand, let alone use it.

Only those elites who have been immersed in mathematics for a long time can use it skillfully.

As for ordinary poor people?

Zhang Yue has seen their embarrassment and shabbyness in the face of this mathematical classic - most people can't even understand the solutions to those equations in Nine Chapters Arithmetic.

There is no way, in this era, there are no Arabic numerals and no formulas.

The ancient Chinese math sages had to use their wisdom to describe mathematical problems. But they were too smart, so the equations they used became extremely complex.

It’s so complicated that even Zhang Yue feels quite awkward.

To solve this problem, we must solve the reality that mathematics is monopolized by the elite.

Zhang Yue knew that he was still unable to catch up now.

Not enough reputation and insufficient strength.

Even if we take out Arabic numerals and mathematical formulas from later generations, few people are willing to use them.

So, he must first gain his reputation in mathematics.

The best is to become a recognized math master in the world.

Only when you become a top student can you use your name as a top student to do things.

After gently tapping the table, a light of inspiration flashed through Zhang Yue's mind. He already knew what to choose to make a breakthrough.

A simple and easy-to-learn method that does not require too much talent can allow ordinary people to master complex and profound mathematics.

Let poor scholars also talk and laugh at mathematics and calculate quickly.

This method is abacus.

The greatest mathematical tool in ancient China.

Before the emergence of computers, humans were the best and most convenient calculator.

However, when Zhang Yue traveled through time, abacus was almost eliminated by society.

The popularity of computers and the development of the Internet have made even professional accounting no longer need abacus.

Abacus formula has long since left the stage of education.

Disappeared on the textbooks and stayed away from people.

Fortunately, as a post-80s generation, Zhang Yue was forced by teachers to recite and memorize abacus formulas when he was in elementary school.

Although, I have basically forgotten it now.

However, it can be traced back.
Chapter completed!
