[Three Kingdoms] Burning incense and sacrificial wine

Cui Song turned around and looked, the direction from which the voice came was a short pavilion, in which sat three Confucian scholars in square scarves and skirts, facing him.

His eyes lingered among the three for a moment, and finally fell on the square-faced scholar on the left with a mocking expression.

This person is about 25 or [-] years old, with a square face and unlined eyebrows, wearing a light yellow long train and no extra accessories on his body.

Apart from the sharp look on his face, it can be said that his facial features are correct, his eyebrows are honest, and he does not have the slightest evil spirit.

Cui Song has always had a built-in filter function for the trash talk of insignificant people, acting as if the other party is venting against the wind.

So he saluted the three of them gracefully, cupped his hands as if praying before cooking, and prepared to take a detour to leave.

"Wait a minute—"

Cui Song kept walking.

"Wait a minute—"

Keep going.

"Cui Song, stop!"

Cui Song stood there, pretending to be surprised and folded his body: "Are you calling me?"

His expression does not seem to be fake, but it seems to be extraordinarily rude——

First, he omitted the title and didn't know what to say, and then made a lot of noise.Especially in the last sentence, the tone was raised because of the eagerness, which caused several officials nearby to frown, stop talking one after another, and looked over with hesitation.

The square-faced scholar's face turned red and then pale.

Sensing the indistinct scrutiny around him, his face burned a little, and he secretly cursed the family's habit of putting on a show, and walked out of the pavilion with a flick of his sleeves.

I thought that with the arrogance of these so-called geniuses, the initial provocation was enough to anger them.It doesn't matter if you retort, or get angry, as long as you break out at this meeting, no matter how talented you are, you will inevitably get the bad name of being narrow-minded, disrespecting your predecessors, and letting go of your talents.

But he didn't expect that Cui Song was young, but he had great tolerance. He not only pretended not to hear his ridicule, but also saluted him as if nothing had happened, turned around and left?

As the teacher said, none of these aristocratic families are good people who are deeply scheming and seek fame.

Thinking of his family's unparalleled talent, but because of his birth, he was overwhelmed by the family officials everywhere, and his teacher who had been unsuccessful all his life, the square-faced scholar hid the enthusiasm in his eyes, and walked up to Cui Song under the gaze of all the scholars.

"Hanyang He Wei, an unknown soldier, has heard of your name for a long time. Wei wanted to talk to you, but saw you passing by in a hurry, and couldn't avoid it, so he couldn't help being anxious... If there were any inappropriate words and deeds just now, you can still Wang Haihan."

The scholar who called himself He Wei spoke politely, but there was a needle in his words: Senior wants to discuss literature with you, why are you hiding?Could it be that he dislikes that this senior has no talent and reputation and is not worthy of talking with you?

In addition, he also explained his gaffe: because he was eager to exchange knowledge with celebrities, he was impatient and ignored the issue of politeness.And the reason why he was impatient was because this "celebrity" turned a blind eye to him.

Cui Song may not understand all these twists and turns and insinuations, but he can sniff out the malice buried in it even if he pinches his nose.

Thousands of words, Cui Song responded with one word: "Dear man, I just went to change clothes..."

——I just went to the bathroom, so I greeted you and left. Is there anything wrong?

As soon as they heard that He Wei stopped people halfway to prevent them from going to the bathroom for the sake of so-called discussion, everyone's eyes on He Wei suddenly became very subtle.

He Wei almost couldn't catch his breath: "You—"

Cui Song bowed his sleeves together, and said with a smile: "Thanks to brother He's kindness, since that's the case, why don't we go together?"—to the toilet?

Hearing his subtext, everyone around laughed.He Wei's face turned pale, believing that the aristocratic families around him were colluding and deliberately watching his jokes, so he stopped showing his so-called demeanor and smiled coldly.

"It's okay. You and I have a contest first, and then it's not too late to change clothes."

Trying to ignore the strange gazes around him, He Wei straightened his back: "I heard that Qinghe Cui Lang could recite at the age of three, master Fu at the age of eight, his calligraphy is like a fairy cloud, and he is proficient in all six arts. Today I want to compete with you, do you agree or not?" Shouldn't it?"

Cui Song asked: "Do you want to compete with me in poetry?"

He Wei had a sneer on his face, with a look of "You think I'm stupid": "Who doesn't know that Qinghe Cui Lang is the best at composing poems and fuss? Get the ax out of class."

Cui Song held back the corners of his mouth from rising: "How are you doing?"

He Wei said: "Since it's 'a gentleman who knows all the six arts', how about comparing the 'number' among the six arts with me?"

Polytechnic Wang Cuisong: ...

He Wei said disdainfully: "But are you afraid?"

"How do you want to compare?" Cui Song folded his sleeves together and pinched his palms under the sleeves.

He Wei described the plan of the competition.To put it simply, in fact, they each set up questions to test each other's "counting" ability.

Cui Song "generously" gave He Wei the right to come up with the first question—it has nothing to do with underestimating the enemy, let alone a foolish way to pay attention to humility. In fact, Cui Song has never read ancient mathematics books, and he doesn't know what the ancient mathematics questions are. Therefore, he had to kick the ball to the opponent and wait for the opportunity.

He Wei asked a question: "Now there are Tian Guang 360 six steps, from 430 three steps, what is Tian's geometry?"

Cui Song: ...

The onlookers whispered.

This question is evolved from the field calculation method in "Nine Chapters of Arithmetic". The question itself is not difficult, but due to the large number, it is difficult to solve it in a short time.If you don't bring calculating chips[1] and pen and paper, it will be even more difficult to do mental calculations.

One person said: "This He Wei is really good. He is good at 'counting', so he encouraged Cui Jiaxiaolang to compare 'counting' with him, and use his own strengths to attack others' weaknesses. Is this the style of Hanyang poor scholars?"

The people next to him echoed.

"Exactly. Fortunately, He Xiaotu (He Wei's character) is a few years older than Cui Lang, and he is a member of his father's generation. How can he not be ashamed to make things difficult for a young adult who has not reached the crown?"

"According to him, Cui Lang is good at writing, and Bi Wen is a classmate; but why doesn't he say that he is good at 'counting'? Comparing 'counting' with Cui Lang is justice? Good sense, good justice, I should feel ashamed for him smell of urine."

"Surely a lowly Confucian! I am ashamed to sit with this person!"

……

The two Hanyang scholars who came with He Wei couldn't help covering their faces with their sleeves.

But there are also rigid and pedantic old scholars who can't understand Cui Song's "negligence".

"He Xiaotu is indeed contrary to the style of a gentleman, but is this Cui family child too arrogant? Mr. Ang said: The son of a daughter does not sit in the court, and the Cui family's child is famous, but he wants to use his own shortcomings to attack others. Chang... if he is defeated by this little-known poor man here, how will he face the dead He Gong?"

The young scholars didn't take it seriously, but it was the old elders who spoke out, and it was inconvenient for them to argue, so they pretended not to hear them, and continued to whisper, discussing together in twos and threes.

Cui Song naturally also heard the words of the old scholar. He smiled nonchalantly, and quoted the famous saying of Han Yu in the Tang Dynasty: "There is a priority in learning the Tao, and there is a specialization in the art. Brother He and I discussed the Tao today and complemented each other. Insufficient. If you lose today, your skill is not as good as others, and you will be willing to bow down. Isn't it self-deception to excuse your own shortcomings, others' strengths, or use your age as an excuse?"

The old senior stroking his beard, chewing on the words "there is a priority in hearing the truth" and "the lack of complementarity", his face softened slightly.Hearing the words behind him, he couldn't help being a little moved: "Don't blame He Gong for being so fond of young people. The students of 'Xuehai' have the style of a gentleman, and they behave like a barbarian, so they deserve a virtuous name."

He Wei couldn't get used to the demeanor of the aristocratic family's son, even if he lost, he looked superior, and he was furious in his heart: "If you can't answer, you can't answer, if you have to talk about it—"

Cui Song opened his mouth and replied, "One hundred and fifty thousand and eight thousand four hundred and seventy-eight steps."

He Wei was startled.

The scholars around were also startled, but seeing He Wei's expression, the answer was obviously correct.

Since He Wei dared to pose a question, he would definitely calculate the correct answer in advance.But he spent a lot of time using calculation chips[1] and paper and pen calculations at that time. Cui Song has neither calculation chips nor a pen, so how could he get the correct answer of six digits in a short period of time?

He Wei didn't believe in evil, and believed that Cui Song must have done the same problem beforehand, so he explained the problems he had prepared earlier, and even the problems he had studied in his daily life.

But without exception, Cui Song solved the correct solution in a short time.

"This is impossible!"

"With the heart as the starting point, the heart is as clear as a mirror, how can it be impossible." Cui Song said inscrutablely, what he thought in his heart was: These are all junior high school math problems, multiplication and division, circle calculation, approximation, square root. Chickens and rabbits in the same cage. XY solving equations, science students also have dignity.

As long as you have a formula, you can analyze the problem and understand the principle, the math problems are always the same, and there is no problem that cannot be solved.Of course, complex numbers are more difficult to calculate, but who is he?The representative of the Chinese team in the Z World Abacus and Mental Arithmetic Competition, the top ten in Group A, calculated three-digit multiplication and division twice in his mind.

He Wei's face was ashamed, and then he thought about it, now it's just Cui Song who answered his questions, if he can also answer Cui Song's questions, then the two are still tied, and he has not lost to this young aristocratic family son!

Rejuvenated, He Wei folded his sleeves and bowed: "Teach me. Please write a question."

Cui Song's topic is: Given that the radius of the ball is 1 foot, find the volume of the ball.

This is also the content of middle school mathematics.However, there is no Archimedes or Zu Chongzhi in this era. Although there is Liu Hui's circle cutting technique, there is no precise formula for calculating a sphere.

——Here, he needs to thank his hard-working mathematics teacher, who did not forget popular science when teaching mathematics #中国名庆研究二三事#.

Cui Song, who silently dug a hole for the other party, did not forget to list a hundred compliments for his previous math teachers in his heart.

He Wei also didn't expect Cui Song to ask such a question, but he soon woke up from the surprise, and the original uncertainty was replaced by disdain and ridicule.

During the Qin and Han Dynasties, the formula for calculating a sphere was V=9/16D3, which was the "Nine Chapters of Arithmetic"—that is, the sphere calculation criterion in the authoritative mathematics textbook.

Although Liu Hui, who invented the circle cutting technique, proved that the formula of the sphere was wrong with the theory of "Mou He Fang Gai", but with Liu Hui's great talent, didn't he not find the correct formula for the volume of the sphere?

Since there is no correct answer, the formula in "Nine Chapters of Arithmetic" is the answer.Even if everyone knows that the formula may be inaccurate, so what, you can't solve the difficult problem that even mathematics can't solve?

Well, even if you give another calculation method, how do you prove that your algorithm is correct?

He Wei originally thought that since Cui Song had such a strong ability to calculate numbers, it might not be certain that he could create some amazing numbers problems.Who would have thought that he would talk the same old-fashioned way, embarrassing others with a question that has no correct answer at all, but he didn't know that what he thought was embarrassing was actually embarrassing himself.

He only needs to answer with the arithmetic theory of "Nine Chapters of Arithmetic". Who can say that he is wrong?How many people regard "Nine Chapters of Arithmetic" as a heavenly book, and "Mou He Fang Gai" is just a theory on paper, how many people can believe it?

Thinking of this, He Wei shook his head regretfully: "Change the topic."

Such a simple and easy-to-answer question, even if he answered it, it would be useless, leaving nothing to talk about.

Cui Song saw He Wei's contempt, and didn't point it out: "No need, just this one."

He Wei reported an answer according to the formula of V=9/16D3.

然而，在现代接受九年义务教育、且数学课上没有发呆走神的学生都知道，球形体积的公式不是什么V=9/16D3，而是V=4/3πR3。

The approximate value of π is 3.14, and the more precise value is 3.1415926... an infinite non-repeating decimal.

Cui Song has memorized the mantra of "One Temple, One Pot of Wine on the Top of a Mountain", and he can memorize it to 20 decimal places of π. With the correct formula, he can calculate a more accurate answer.

Cui Song reported another number, but He Wei didn't believe it, and accused Cui Song of making up the answer at will.

Just as he was about to refute, suddenly there was a loud and clear voice, which was reckless and careless.

"That being the case, why not check it out?"

Everyone heard the sound and looked, only to see a young man about the same age as Cui Song walking out of the small path, with disheveled hair, but wearing a crown, eyes like cold swords, nose like dark courage, wearing a casual long suit, Dragging the ground and stepping on wooden clogs, they come in style.

The young man ignored He Wei who was glaring at him, and made a detour to Cui Song.

Although his face is a bit smaller than Cui Song's, his stature is sufficient, not only half a foot taller than Cui Song, even the adults around him are slightly shorter than him.

Because of his approach, it seemed that the air in this area was covered, thick and settled.

"Since you came up with this algorithm, why don't you spend some gold and silver and make a few gadgets to prove that what you said is not a lie?"

The young man leaned forward slightly, staring straight at Cui Song, his eyes seemed to be scrutinized, but there seemed to be nothing.

He Wei, who was ignored, couldn't help ridiculing: "Why, do you think his absurd calculation is correct? Or...you are also a fan of Cui Lang's 'A Fu Xiao Qian Qiu', and you couldn't wait to speak for him. Come to conquer me, a poor man who is overconfident?"

"One Fu laughs thousands of years?" The young man spit out the word slowly, and looked sideways at the square-faced Confucian scholar, and his already compelling aura became even more rampant.

The old Confucian who scolded Cui Song as "insolent" before, this time he saw what real "insolent" is.

"How can you 'smile a thousand years with a song'?"

He Wei was taken aback by the young man's belittling words: Isn't this person on Cui Song's side?

He tentatively asked: "What do you think of Cui Lang's talent?"

The young man smiled, half mocking.

He opened his thin lips lightly, and spoke four words calmly and firmly:

"But err."

But that's all.

He Wei was overjoyed, and was about to get close to the young man, but he heard the other party's voice change.

"—To me, it's nothing more than mediocre; ignorant rats like you can't even flatter a horse." The young man pursed his lips, and tapped the grass field on the east side of the garden with his slender fingers. Not a horse, but a donkey."

The word the boy used was "you".

This time, not only He Wei's face was ugly, but also many scholars who had been glanced at by the young man also looked sullen and glared.

Cui Song was stunned by the young man's arrogance and ability to attract hatred, and couldn't help asking the question that everyone present wanted to know: "Who is the gentleman?"

The author has something to say: In order to avoid misunderstanding, I solemnly declare:

It's not Guo Jia who came out here... Let me tell you something important.Because Feng Xiao is one year older than Song Song, not younger.Just as wild, but less crazy (at least on the surface).

Although I would love to have Guo Jia appear immediately...yet!

(Hold your face and compare your heart) There is a word called finale.
