Take the imperial examinations with the red envelopes of the writers

I saw the Jiugong grid on Xie Linfeng's manuscript paper. The first line filled in the three numbers "two, nine, and four" from left to right, and the same position in the second line was the three numbers "seven, five, and three". The rows are "six, one, eight" in sequence.

Su Yan did a quick calculation in his mind. Indeed, the sum of the numbers on each horizontal line, each vertical line, and even two diagonal lines is fifteen.

Xie Linfeng is hiding something!

Su Yan cast admiring glances at the little friend beside him.

"Amazing, thank you, Young Master!" Song Zixiu teased.

Zhou Yunwen was about to ask Xie Linfeng how to solve the problem, but at this time Master Fu also noticed them. He stood behind Su Yan and looked at Xie Linfeng's solutions together, and nodded with satisfaction.

"That's right, that's right! Are you interested in trying more difficult questions?" Fu Fuzi looked at Xie Linfeng with a smile and asked.

"Of course! Master... I can definitely do it!" Xie Linfeng replied immediately, patted his chest, and looked confident.

Master Fu smiled even more happily, and he was going to take a pen to write a new question for Xie Linfeng.

Unexpectedly, there were no writing brushes on Xie Linfeng's desk, only charcoal pens produced by Songzhuzhai.

Master Fu looked at the charcoal pen with great interest, picked it up and drew a sixteen-square grid with four horizontal lines and four vertical lines on Xie Linfeng's manuscript paper.

This is to upgrade the difficulty to a fourth-order magic square, and you need to fill in the sixteen numbers "one to sixteen".

Fu Fuzi didn't even reveal how much the sum of the numbers in each row and vertical should be this time.

However, Xie Linfeng stared at the sixteen grids without thinking for a long time, and just picked up the charcoal pencil and started to fill in.

Su Yan watched his subordinates not stop, and he got the result after a while.

"Interesting!" Fu Fuzi looked at Xie Linfeng with more kind eyes, this is a good seedling in arithmetic!

"How did you come up with it?" Zhou Yunwen was also very surprised. Seeing how Xie Linfeng did the question just now, he was so smooth and smooth, it wasn't luck or just making up numbers at all.

"Hey, it's easy!" Xie Linfeng almost wrote the words "As expected of me" on his face at this time.

"Just fill in these numbers from the first horizontal row in ascending order from small to large, then reverse the upper and lower numbers, and reverse the left and right numbers, and finally stick out the four middle numbers. .” Xie Linfeng said eloquently, his slender hands pointing at the manuscript paper to signal everyone.

"Yes, this is indeed a solution to the vertical and horizontal diagram." Master Fu nodded.

He glanced at Xie Linfeng admiringly, then walked to the classroom and explained the various solutions of the vertical and horizontal diagram.

Su Yan obediently took out his notebook and wrote down one by one.

After Master Fu finished explaining, he felt that the atmosphere was not mobilized enough, so he continued: "Here is another interesting topic, let's see if you can come up with it."

Xie Linfeng sat up straight when he heard the words, with a look of anticipation on his face.It's time for me to show off my talents!

"This is a question from the "Sunzi Suanjing": Today there are pheasant and rabbits in the same cage, with 35 heads on the top and 94 feet on the bottom. How many are the pheasant and rabbits?"

The meaning of this question is: put a number of chickens and rabbits in the same cage, count 35 heads from the top, and 94 feet from the bottom, how many chickens and rabbits are there in each cage? What about a rabbit?

Appeared!

Chicken and rabbit in the same cage problem!

For a moment, Su Yan felt that there was nothing to say.

Which old farmer is keen to put chickens and rabbits in one cage!

Big brother, there is no need to save cages like this!

On behalf of the chicken and the rabbit, I disagree with this practice.

However, Su Yan can do this question. After all, he still has an impression of linear equations in two variables, but the solution is inconvenient to explain to others.

Xie Linfeng rolled his eyes, thought for a while and said loudly: "There are 23 pheasants, and [-] rabbits!"

As soon as he finished speaking, the eyes of all the students fell on him.

Master Fu looked at him eagerly.Yes, this kid really has a bright future.

"How do you solve this problem?" Master Fu decided to ask Xie Linfeng to demonstrate.

"If both the pheasant and the rabbit raise one leg, the pheasant becomes one-legged, and the rabbit becomes two-legged. The total number of legs becomes 47, and the total number of heads becomes 35. Only." Xie Linfeng paused and continued.

"In this way, the number of heads of pheasants is the same as the number of feet, and the number of feet of rabbits is twice the number of heads. From this we can see that if there is a two-legged rabbit, the number of feet will be one more than the number of heads. Therefore, the number of feet of one-legged pheasants The difference between the number of feet and the number of heads of two-legged rabbits is the number of rabbits, that is, 47 minus 35, and there are twelve rabbits. Then subtract the number of rabbits from the number of heads to get the number of pheasants , that is, subtract twelve from 35, and you get 23 pheasants."

Xie Linfeng finished speaking in one breath, his eyebrows beaming.He sighed in his heart, I also want to keep a low profile, but my strength does not allow it!

"That's right, that's exactly the solution." Master Fu nodded with satisfaction.

Su Yan raised his eyebrows and looked at Xie Linfeng, yes, I didn't expect an expert to be by my side.

Next, Master Fu began to explain the curriculum arrangement of this mathematics.

The arithmetic of Yunshan Academy is mainly based on "Nine Chapters of Arithmetic", explaining the problems mentioned in it, "Fang Tian, ​​Corn, Decline, Shao Guang, Shang Gong, Even Losing, Profit and Deficiency, Equation and Pythagorean."

The content of "Nine Chapters on Arithmetic" is very rich, including various practical problems about production and life.For example, "Corn" explained the problem of the conversion of grain and grain ratios, while "Equal Loss" studied the problem of reasonable distribution of taxes.

Master Fu also talked a little about the bibliography - Ten Books of Suanjing, and strongly suggested that students go to Wenjinge to borrow this bibliography and read it carefully.

Su Yan tremblingly wrote down the ten mathematics books.

I was physically and mentally exhausted from being tortured by arithmetic in the morning, and I had to continue the law class in the afternoon.

The teacher who taught the law was surnamed Yue, and he seemed to be a shrewd and powerful middle-aged man.

Master Yue's clean hair was tightly tied with a plain hair crown, leaving no strands of hair that wanted to break the rules.The robes were clean and neat, well cut, and even the corners of the robes were hanging peacefully.

Master Yue swept his eyes, and everyone immediately sat upright, feeling an inexplicable sense of oppression.

"The law is the balance of the country, and the yardstick of the time. Balance determines the weight, and the yardstick is straight. Only follow the law of three feet, and guide the people of the world." Yue Fuzi said slowly.

His voice was up and down, sonorous and powerful, and all the students were inspired.

Master Yue spent half an hour explaining the importance of the law, citing extensively, which made the students stunned.

Then he began to explain the method of law examination in the imperial examination.

The investigation of the law was also an essential part of the imperial examinations in the Davidic Dynasty.In addition to using short-answer questions to examine the provisions of the Davidic Law, candidates are also required to be able to judge books.

The examinations of the township examinations and general examinations generally select real and difficult cases from the official files of various prefectures, states, and counties, and let candidates write judgments based on the cases and make judgments, so as to test the candidates' understanding of the law and consider Whether it has the ability to handle affairs for officials.

Shujue refers to the official judgment document, which is an official document written by the judge officials after distinguishing right from wrong based on the actual circumstances of the case, punishing suspects with criminal names and properly resolving civil disputes.

The written sentence has a prescribed format, which must include the criminal's name, place of origin, age, residence, occupation, etc.Of course, the facts of the crime, the reasons for the crime, and the evidence are also indispensable.

Of course, the most important thing is which legal provisions to invoke and what judgment to make.

In the book judgment, the "judgment" for the handling of difficult cases is specifically presented in accordance with the examination requirements as the verdict.

If the verdict is sharp and ingenious, making people's eyes shine and admiring, at least the written judgment in the imperial examination has passed.

The difficulty lies in the judgment of the book, how to combine the concept of humanistic care in Confucianism with the just, strict and impartial legal provisions, turn bad fate into good fate, achieve the effect of four or two thousand catties, and make a verdict that convinces the common people .

"Having said so much, I still have to let you experience the case so that you can feel and understand it more." Master Yue smiled slightly and stood with his hands behind his back. He raised his voice and said, "Listen, everyone!"

The students in the classroom held their breath and pricked up their ears.

Su Yan also opened his beautiful almond eyes, which were full of light.

"There are two families in a certain village. One lives at the head of the village and the other lives at the end of the village. Each of them feeds a big cow." Master Yue's storytelling style is also cadenced and paused properly, making people curious about what happened next. develop.

"One day, two bulls ran up the hill to graze. As a result, their stomachs were full and their eyes turned red for some reason, and they fought with each other. The two bulls put their heads against their heads, and their horns against their horns."

Master Yue's few words were very vivid, as if two cows were full and began to ask the other party to kneel down and call Dad.

"Inadvertently, the village-tailed ox lost its footing and fell off the cliff to his death. The village-headed ox was seriously injured in the fight. One of the two oxen died and the other was injured, and the two families had a quarrel. Open the hand, report to the county government and ask the county magistrate to make the decision."

"The owner of the village tail cow lost a cow in vain. Of course, he is angry and wants the other party to pay for it. But the owner of the village head cow is not willing. He only asks how can someone pay for it when animals fight? Well, if you are the county magistrate at this time, what should you do?" How to judge the case?" Master Yue asked meaningfully.

This... the two cows have nothing to do with fighting and fighting, so it has nothing to do with the owner's business.But it is not justifiable for a family who has lost a cow to lose a cow in vain.

There were rustling discussions in the classroom, Master Yue was not dissatisfied when he saw this, he still stood calmly and calmly, waiting for the students to think about the sentence.

"If you want me to say, the family with the cow at the head of the village should compensate the family with the cow at the end of the village." Xie Linfeng and Su Yan discussed, "After all, the cows are gone."

"But how to compensate? What to compensate? How can both families be satisfied? This is all debatable, and this is the difficulty." Zhou Yunwen pointed out the embarrassment of this judgment.

Su Yan's slender right hand was slightly bent, and his knuckles tapped lightly on the table.

He was thinking in his heart: how to define the value of this cow?Do you want to find an old farmer who knows cattle to judge how long the dead village tail cattle can plow?Then convert the cost of the village head cow's injury and compensate the owner of the village tail cow?How to calculate the manpower and material resources required for the appraisal?

Su Yan thought about it, but still felt that it was inappropriate and extremely troublesome.

Suddenly he had a flash of inspiration, and he had an idea.

The author has something to say: Chicken and rabbit in the same cage old farmer: No one knows how to use the space of the cage better than me!

"Book Judgment" is a private establishment!Refer to the Sui and Tang Dynasties' private selections, please don't get too deep into it, just watch it for fun, bow!

The problem of chicken and rabbit in the same cage comes from "Sun Tzu's Mathematical Classics".

The solution to the magic square: "Just arrange the nine natural numbers obliquely in increasing order from small to large, then reverse the upper and lower numbers, and the left and right numbers; finally, push the four middle numbers outward. "From Yang Hui, a mathematician in the Southern Song Dynasty, "Continuing the Algorithm of Picking Oddities from Ancient Times".

"Ten Books of Suanjing" refers to: "Zhoubi Suanjing", "Nine Chapters of Suanshu", "Sea Island Suanjing", "Sun Tzu Suanjing", "Zhang Qiujian Suanjing", "Xiahouyang Suanjing", "Jigu Suanjing", "Five Cao Suanjing", "Five Classics Suanshu" and "Zishu".

"The law is the balance of the country, and the criterion of the time. The weight is determined, and the criterion is upright." It comes from "Zhenguan Political Leaders Fairness" by Wu Jing in the Tang Dynasty.

"Only follow the law of three feet, and lead the people of the world." It comes from "Zhenguan Political Leaders Fairness" written by Wu Jing in the Tang Dynasty.

The example of the two cows' judgment comes from Wu Sugong's "Ming Yu Lin" in the late Ming and early Qing dynasties.
