Be a master through ancient times

The temptation to leave a name in history is too great. After serious consideration, the officials of the Department of Education raised their hands and voted on this matter.The result was very gratifying. Except for two abstentions who had too many concerns, it was almost unanimously passed.

Now that he had made up his mind and time was running out, Chu Ci began to arrange this matter.Of course, before arranging work, he also wrote an official letter and handed it up.After all, he is just a school, and there are two immediate bosses above him, so it's not good not to inform them in advance.If they learn about it from other people in the future, Chu Ci will have a reputation of being arrogant.

Qi Luzhi didn't like Chuci as always, and only glanced briefly at the official document he presented, and then commented "whimsical", and then ignored it.Du Yu was different. After carefully reading the official documents, he went out in plain clothes and came to Zhangzhou Mansion.

When he arrived, Chu Ci was holding a meeting for everyone, and when he heard the porter report that there was an old man at the door, he couldn't help but feel puzzled.After listening to his description, Chu Ci roughly understood the identity of the visitor, so he suspended the meeting and greeted him at the door in person.

Outside the gate of the Tixue Division, Du Yu raised his head with his hands behind his back, staring intently at the couplets pasted on both sides of the Tixue Division's gate, on which was written "There is a road to the mountain, but diligence is the path to learning the sea" in a sharp and thin font. There is no limit to make a boat with suffering" these two sentences.These two sentences turned into poems, from the students' self-encouragement to the earnest consolation, which is also suitable for posting at the door of the Tixue Division.

Of course, what Du Yu observed was not the content, but this unique font. He had long heard that Chu Ci was well written, but now it seems that others did not exaggerate.

"Master Du, why didn't you let me know when you came? It seems that we are neglecting, please don't take offense." Chu Ci and Du Yu share the same interests, and now the eight-character motto of "patriotism, dedication, integrity and friendliness" is still hanging on Du Yu's It's in the study, so when Chu Ci talks to him, he won't be too restrained.

Du Yu smiled: "There is nothing wrong with it, so why bother working with local officials?" If you compare his position with modern times, it is equivalent to the director of the Provincial Department of Education going to the city to inspect, and the local officials have to personally receive him. Accompanied by.

Chu Ci also smiled, and the old man brought a servant over, it seemed that he really didn't intend to alarm others.Moreover, he went straight to the Tixue Office as soon as he came, presumably for the official documents he presented a few days ago.

Sure enough, as expected by Chu Ci, Du Yu went straight to the point before he reached his study, expressing his desire to hear the specific regulations Chu Ci formulated for the compilation of textbooks.

This matter cannot be explained clearly in a few words, and there are still a group of people in the meeting room, so Chu Ci simply didn't enter the study room, took Du Yu around a corner, and came directly to the meeting room.

These officials were still discussing, when they suddenly saw Tixue walking in with an old man.When they saw the old man's appearance clearly, they immediately panicked. Why did Mr. Zheng Tixue come to Zhangzhou Mansion suddenly? Could it be that he wanted to make an unannounced visit to see if they were serious about their errands?

Everyone had a lot of thoughts in their hearts, but the movements of saluting seemed to be agreed in advance, and they looked particularly uniform.

Du Yu asked them to excuse them with a smile, and then said that he came today to ask for advice, and you don't have to be so restrained, just pretend that he is not there.After speaking, he found a seat in the front row and sat down, waiting to hear Chu Ci speak.

Seeing this, the others all sat upright, making the atmosphere in the meeting room very serious.Standing alone above Chu Ci in full view of everyone, he suddenly felt a little pressure in his heart.

Just as he was about to speak, Du Yu suddenly raised his hand: "Lord Chu, can you ask them to bring me a blank notebook too?" Looks like a lot of hard work ahead.

Naturally, his appeal could not be ignored, so Chu Ci immediately signaled the boy outside to bring a set of paper and pens.Du Yu looked at his writing brush, then at the apparently small and hard charcoal in their hands, a trace of puzzlement was scratched across his face.

This charcoal is actually a charcoal pencil, because ordinary charcoal is brittle and will break if you use a little force, so Chuci found a lot of people who can burn charcoal to find a way, so they used a kind of tree called iron wood to burn out This is a hard, unbreakable charcoal pencil.You may get your hands dirty when you use it, but you only need to roll a piece of straw paper on the outside, and the appearance is similar to that of a modern pencil.

This thing is only used internally by the Tixue Division, and Chu Ci has not been promoted outside.The reason is that the current test papers are still answered with a brush. If those children who have just entered school are used to using a pencil, the calligraphy will definitely not look good.However, some people in the market have already learned how to use it. Like those accountants who do calculations all day long, they feel that charcoal pens are more convenient than brushes.

Chu Ci didn't notice the expression on his face, because he had already lost time just now, so after he came to the stage, he continued to arrange tasks.

"...We just talked about the compilation of the book on mathematics. I would like to ask everyone, what do you think of the numbers used by the big cannibal?"

As soon as Chu Ci's voice fell, someone raised his hand: "Your Excellency can say those crooked words? I have stayed in the official post for a while, so I know something about this thing."

"In that case, please come up and write it on the blackboard, Mr. Huang." Chu Ci thought they had just heard of it, but now there is someone who can write it, so he immediately grabbed the young man and came up.

Mr. Huang recalled those numbers, then picked up the chalk, and wrote down the ten numbers from zero to nine on the blackboard with a little jerk, and then wrote the numbers in capital letters next to them.

To those who have never been in contact with them, these numbers look like earthworms, but to Chu Ci, they are quite familiar.In order to force himself to adapt to the ancient society, Chu Ci almost never used these numbers, but whenever he needed to calculate, he used abacus or codes, and these two methods are more popular now.However, compared to the calculation methods he learned since childhood, these two methods are a bit more difficult.

"Master Chu, do you want to use this kind of numbers in your math book?" Some people are sensitive to something, and they never talk nonsense when learning, so his purpose of introducing these things in public is very clear.

Chu Ci gave him an appreciative look, and they said that there are too many people who know the elegant meaning after listening to Xiange, and the meeting is really great.

"That's right, what I want to talk about is this kind of number. Master Huang, since you can write this kind of number, do you know their calculation method?"

Master Huang shook his head, and said: "These big cannibals regard it as a secret method, and they are not willing to pass it on easily, and I only know how to write it."

Chu Ci nodded. Naturally, those businessmen did not come here for the purpose of preaching the scriptures, and it is reasonable to refuse to disclose it.But it doesn't matter if he reveals it or not, he will anyway.

"By chance, I have learned some methods to solve problems. If you are interested, you can take a look." After Chu Ci finished speaking, he picked up the chalk and wrote four symbols on the blackboard, and then used These adults are familiar with the language to explain what is addition, subtraction, multiplication and division.

These adults have worked with Chuci for a long time and are already familiar with his way of speaking, so it didn't take a little time for them to understand the meaning of these symbols.Du Yu looked at the crowd and couldn't help but sighed in his heart. He was actually a little puzzled.I remember that when I was studying in the school, I was also among the best, but now I am also lagging behind. Time really makes people grow old!

After explaining the symbols clearly, Chu Ci wrote four arithmetic problems on the blackboard, one for addition, subtraction, multiplication and division.Then he said: "Everyone might as well do the math together and see who takes the shortest time."

These are simple two-digit calculations. These adults calculated in their minds while comparing the numbers, and quickly came up with the answer.Ancient calculations and multiplication also used oral formulas, but their formulas are small nine-nine tables, that is, the ones that are recited upside down.When calculating division, most of them use the trial business method, which is relatively profound and difficult for ordinary people to use proficiently. Therefore, in the Xiucai test, if there is a division problem with more than three digits in any year, then it can be said that this year The test questions are somewhat difficult.

After they finished their calculations, Chu Ci wrote the answer without thinking.

After getting the answer right, Chu Ci erased the above content, and then came up with a few three-digit addition, subtraction, multiplication and division. Now the calculation of multiplication and division is a bit difficult.It took a while for the adults below to figure it out gradually.

Chu Ci once again wrote out the answer effortlessly, and when he wanted to come up with a four-digit question, an official raised his hand and asked if he could ask for a question.

Chu Ci only thought for a while, then understood his thoughts, and nodded in agreement.The man didn't stop after he came up, and he made a problem with the chalk.

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

As he wished, Chu Ci shook his head in embarrassment, before he could speak, he opened his mouth first: "It's a bit difficult to write directly, but I can compare with you, and four adults will be selected below, one Do one, I'll do four, and then let's compare the speed to see who is faster, how about it?"

"Since your lord said so, let's compare." Four people were quickly selected from the bottom, and one of them was the accountant of the Education Department. All the expenses in the Education Department had to go through his hands. , he is the person who deals with numbers the most in the department.So, everyone gave him the division problem directly.

Du Yu cheerfully made the referee, and after he gave an order, the four began to answer.The officials assigned to addition and subtraction quickly figured out their own problem. When they looked up, they found that Chu Ci's answer had been neatly written on it, which was exactly the same as what they calculated.

The official assigned to multiplication was a little anxious, he had never done the problem of multiplying four-digit numbers.Although there are traces to follow, the speed is very slow.He couldn't help but looked up, only to find that Chu Ci was already calculating division.

The result of the competition is self-evident, Chu Ci is almost an overwhelming victory, but Chu Ci is not very happy, just pick a third or fourth grade elementary school student from modern times, and you can easily figure out the answer.The ancients just didn't master the method, and when they mastered the method, maybe he can't count them as well.

Seeing everyone's expression of thirst for knowledge, Chu Ci didn't hide his secrets, and started to teach directly, teaching them the method of column and vertical calculation without reservation.

No matter young or old, no matter how big or small the official position is, they all take a pen to write and calculate carefully.Through them, Chu Ci seemed to see the young children who would get new textbooks in the future.The math is good, even if you can't make a fortune from the imperial examination in the future, you can still make a living from this.
