The temptation of leaving a name in history is too great. After careful consideration, the officials of the Tixue Department raised their hands to vote on this matter. The result was very gratifying. Except for two people who had too many concerns, they were almost unanimously approved.

Since he had made up his mind and time didn't wait for anyone, Chu Ci started to arrange this matter. Of course, before he arranged the work, he also wrote a document and handed it over. After all, he was just a mansion to study.

There are two immediate bosses on it, and it would be bad if they didn't inform them in advance. If they were told from others in the future, Chu Ci would become arrogant.

Qi Lu did not like Chu Ci as always. He only took a rough look at the official documents he presented, then commented on "thinking", and then threw them aside and ignored them. Du Yu was different. He looked at them carefully.

After writing, he went straight to Zhangzhou Prefecture.

When he arrived, Chu Ci was having a meeting for everyone. When he heard the doorman's newspaper that an old man was invited to see him, he couldn't help but feel confused. After listening to his description, Chu Ci roughly understood the identity of the visitor and suspended the meeting.

I went to the door to greet me in person.

Outside the gate of Tixuesi, Du Yuzheng raised his head with his hands, staring at the couplets on both sides of the gate of Tixuesi. He wrote in a sharp brushwork and thin font, "There is a road in the mountains of books, but only diligence is the path, and the sea of ​​learning is

The two sentences of Wuya make a boat with hardship” are transformed into poems, and they turn from students to self-indulgence to heartfelt consolation. They are also applicable when posted at the door of the Tixue Department.

Of course, what Du Yu observed was not the content, but this unique font. I have heard people say that Chu Ci is good at writing, but now it seems that others have not exaggerated it.

"Mr. Du, why don't you say a word when you come? It seems that we are negligent. Please don't be surprised." Chu Ci and Du Yuzhi are similar, and now the eight-character proverb of "patriotism, dedication, integrity and friendship" is still hanging on Du Yu's

It’s in the study, so Chu Ci is not too restrictive when talking to him.

Du Yu smiled: "It's nothing, why bother to work local officials to travel back and forth?" If he compares his position with modern times, it is equivalent to the director of the Provincial Education Department going to the city to inspect, and local officials must receive it in person.

Accompanying the seat.

Chu Ci also smiled, and the old man brought a servant over. It seemed that he really had no intention of alarming others. And he went straight to the Tixuesi Yamen, probably because he submitted it a few days ago.

From the official letter.

As expected by Chu Ci, Du Yu had just walked into his study and expressed his desire to listen to the specific regulations formulated by Chu Ci for writing textbooks.

This matter cannot be explained in just a few words. In addition, there was a group of people in the conference room, so Chu Ci simply did not enter the study room and took Du Yu to turn a corner and came directly to the conference room.

These officials were still discussing, but suddenly saw them, Tixue and an old man came in. When they saw the old man clearly, they immediately panicked. Why did Tixue suddenly come to Zhangzhou Prefecture? Could it be that they wanted to

We will conduct open and secret investigations to see if they have done the job seriously?

Everyone was full of thoughts, but the actions of the rituals seemed to have been agreed in advance, and they looked particularly uniform.

Du Yu smiled and asked them to waive the gift, and then said that he came today to ask for advice, so everyone should not be so restrained, just pretend that he was not the one. As he said that, he found a seat in the front row and sat down.

Waiting to listen to Chu Ci's words.

Seeing this, the others sat upright, making the atmosphere in the conference room very serious. Chu Ci stood above alone in front of everyone, and suddenly felt a little pressure in his heart.

He was about to speak, but Du Yu suddenly raised his hand: "Master Chu, can you ask them to bring me a blank notebook?" He saw that there was a thick book in front of everyone's tables, and the notebook flipped into the middle and looked at it

It seems that I have put a lot of effort into it.

Naturally, his demands cannot be ignored, so Chu Ci immediately signaled the servant outside to come over to get a set of paper and pen. Du Yu looked at his brush, and then looked at the obvious tiny and hard charcoal on their hands, and a trace of it was scratched across their faces.

Unsolved.

This charcoal is actually a charcoal pen. Because ordinary charcoal is brittle and can be broken with a little force, Chu Ci found many people who can burn charcoal and then used a tree called iron wood to burn it.

This kind of charcoal pen with a hard texture and is not easy to break. It can get dirty when used. Just roll a piece of straw paper outside, and it looks similar to a modern pencil.

This thing is only used within the Tixue Department, and Chuci has not been promoted outside. The reason is that the current test papers are still answered with brushes. If the children who have just entered school are used to pencils, the brush calligraphy will definitely not look good. However, it is on the market.

Some people have learned to use it, such as those accountants who calculate all day long, think that charcoal pens are more convenient than brushes.

Chu Ci did not notice the expression on his face. Because he had just been wasted time, he continued to arrange tasks after he came on stage.

"... We just talked about the compilation of the book "Suanxue". I would like to ask everyone what they think about the numbers used by the cannibals?"

As soon as Chu Ci finished speaking, someone raised his hand: "You can say those curved words? Xiaguan had been in Guanyi for a while and had some understanding of this thing."

"Since that's the case, please ask Lord Huang to come up and write it on the blackboard." Chu Ciban thought they had just heard of it, but now he could write it, so he immediately caught the strong man.

Lord Huang recalled the numbers, then picked up the chalk, wrote down the ten numbers zero to nine on the blackboard in a slightly awkward manner, and then wrote capital numbers next to them.

In the eyes of people who have never been exposed to it, these numbers look like earthworms, but in Chu Ci's view, they are full of familiarity. In order to force himself to adapt to ancient society, Chu Ci almost never used these numbers.

Any calculation that needs to be calculated is done using abacus or coding, which are also the most popular methods now. However, compared to the calculation methods he learned since childhood, these two are a bit difficult.

"Mr. Chu, do you want to use this number in math books?" Someone sensitively noticed something. They never talk nonsense when talking about learning, so the purpose of his introduction to these things in public is very clear.

Chu Ci gave him an admirable look. There are too many people who know the elegant meaning when they hear the string songs. It is amazing to hold a meeting.

"Yes, what I want to say is this kind of number. Lord Huang, since you can write this kind of number, will their calculation method be made?"

Lord Huang shook his head and said, "These great cannibals regard it as a secret method and refuse to pass it on to others easily. I only know how to write it."

Chu Ci nodded. Of course, those businessmen did not come for the purpose of spreading scriptures and sending the Tao. It was reasonable to refuse to disclose it. But it doesn't matter whether he reveals it or not, he will do it anyway.

"By chance, I have learned some solutions to the problem. If you are interested, you can take a look." After Chu Ci finished speaking, he picked up chalk and wrote four simple symbols on the blackboard, and then used it.

These familiar languages ​​to explain what addition, subtraction, multiplication and division are.

These adults have worked with Chu Ci for a long time and are already familiar with his way of speaking, so they understood the meaning of these symbols without a moment. Du Yu looked at everyone and couldn't help but sigh. He was actually a little bit

I wondered. I once remembered that I was at the top when I was studying in school, but now I am behind others. It’s really time to grow old!

After explaining the symbols clearly, Chu Ci wrote down four problems on the blackboard, adding, subtracting, multiplication and division one by one. Then he said: "You might as well calculate them together and see who has used them for a shorter time."

These are simple double-digit calculations. These adults quickly came up with the answer while comparing numbers while calculating in their minds. In ancient times, they used the formulas for multiplication, but their formulas were the "Nine-Nine Table", which is the reverse.

When calculating division, most of them use the commercial method to test the method. This method is more profound and difficult for ordinary people to use it proficiently. Therefore, when the scholar test, if there is a problem of division above three digits in one year, then

It can be said that the test questions this year are a bit difficult.

After Chu Ci finished the calculation, he wrote the answer without thinking.

After getting the answer right, Chu Ci wiped the above content and then came up with several three-digit addition, subtraction, multiplication and division. Now the multiplication and division are a bit difficult to calculate. After a while, some people below gradually calculated.

come out.

Chu Ci once again wrote the answer effortlessly. When he wanted to give a four-digit question, an official raised his hand and asked if he could ask him to give a question.

Chu Ci only thought for a moment and understood his thoughts, and nodded in agreement. The man came up without pausing, and asked the question with the chalk.

"Mr. Chu, can you write the answer directly like you did just now?" He felt that Chu Ci should know the answer.

As he wished, Chu Ci shook his head in embarrassment. Without waiting for the man to speak, he spoke first: "It's a bit difficult to write it out directly, but I can compare with you. Here are four adults, one person

Make one, I do four, and then let’s compare the speed to see who is faster, how about it?”

"Since the lord said that, let's compare." Four people were quickly selected below, one of which was the accounting department of the Tixue Department. All the expenses in the Tixue Department had to pass through his hands.

, He is the person who deals with numbers the most. So everyone gave him the division question directly.

Du Yu was the referee happily. After he gave the order, the four of them began to answer. The officials who were assigned to the addition and subtraction quickly calculated their own question. When they looked up, they found that Chu Ci's answer was already neat.

The ground was written on it, which was exactly the same as what they calculated.

The official who got the multiplication was a little anxious. He had never done the four-digit multiplication problem. Although there were traces to follow, the speed was very slow. He couldn't help but look up, but found that Chu Ci had already

It's calculating division.

The result of the competition is self-evident. Chu Ci was almost overwhelmingly victorious, but Chu Ci was not happy either. He could easily calculate the answer by picking up a primary school student in grade three or four from modern times. The ancients just didn't master the method, wait

They mastered the method, maybe he could not be able to beat them.

Seeing everyone's desire for knowledge, Chu Ci did not hide his own ideas and started teaching directly, teaching them without reservation.

No matter how old or young, whether it is big or small, they all write and calculate carefully with their pens. Through them, Chu Ci seemed to see the young children who will get new textbooks in the future. If he had a good math, he would be able to make a fortune even if he could not make a fortune by the imperial examination in the future.

Let's make a living by chatting.
