The beginning of the Three Kingdoms Cheng Yuanzhi

Chapter 61 Contest
Kuangshi Yunmeng, when all the celebrities in Luoyang heard this name, their hearts would involuntarily tighten.

Every time "Yuan She" came to Luoyang, everyone's conversation changed from current affairs in the world to topics such as "Who did Yuan She piss off today", "Whether he pissed you off hard", "Have you vomited three catties of blood?" and other topics.

After that, everyone will bet enthusiastically on who the next person will be.

The people who sit in the bank are usually well-known celebrities with high moral standards. Taking Zheng Xuan as an example, they always make huge profits.

Everyone is afraid and happy about "Yuan She", fearing that his mouth is as cheap as a knife, and one day he will be slapped on his face and lose face: he is happy that he is quick-witted, and he is a rare genius.

Therefore, when it was learned that he was about to come to ask Zheng Xuan, the master of Confucian classics, the circle of celebrities exploded in an instant.

As we all know, Zheng Xuan is the most prestigious master of Confucianism and Confucian classics after Ma Rong.

If such a respected and well-educated elder was beaten up by a young man, it would be no less than an earthquake.

Unfortunately, "Yuan She" came here in the name of teaching mathematics, and happened to scratch Zheng Xuan's itch.

Both of them are good at arithmetic, especially the former, who used arithmetic to kill Yang Chou. This matter is an internal matter of the Black Mountain Army, and no one has recited it on the official level, but it has been passed on in the public.

What happened next was almost predictable.

This must be a needle-to-wheat exchange...

While everyone was overwhelmed with melons, they secretly sweated for Zheng Xuan, hoping that Zheng Xuan would be able to overcome the stunned head and defend the name of the master.

Although it is said that there is no priority in learning, and the master is the teacher, but if the master loses, it will lose face.

After finally waiting for the day of the meeting, the celebrities who came after hearing the news filled the Dongcheng Teahouse to the brim.

As the doorman sang promises, everyone's eyes were fixed on the door.

A scholar about 25 or [-] years old appeared there, wearing a feather fan scarf and wearing white clothes. His resolute face was carved like a knife and an axe, and his steady steps were like a tiger patrolling its territory.

The image is extremely cool...put it in a cup.

Everyone curled their lips secretly.

This is Cheng Yuanzhi’s second visit to Dongcheng Tea House.
Normally, he would definitely not come to this poor place, because this is the stronghold of the party members.

Celebrities talk about "classics" and talk about "ancient precepts" when they talk about it. If they talk too much about it, it will annoy anyone to death.

This is actually nothing, a common problem of cultural people.

But they formed a clique for personal gain.

The formation of cliques among scholars and the formation of alliances between aristocratic families are both extremely troublesome issues for those in power.

These people control culture, public opinion, and contacts in celebrity circles. While you have to use them, you also have to worry about them, lest they make a huge mess.

If Shangdang County wants to develop rapidly, it cannot do without the help of scholars. If everything is done by oneself, it will be exhausting.

Cheng Yuanzhi didn't want to be like Cao Cao, killing celebrities like butchering chickens, one knife at a time, and then completely offended the scholar group, and no one would help him, so he had to promulgate the order of seeking talents "only talents" to use poor people.

So now, he has to come.

Taking the opportunity of exchanging mathematics, he won Zheng Xuan, convinced many famous people with high-level eyes, and brought a few back by the way.

"Duke Zheng, the kid is being polite!"

Cheng Yuanzhi quickly glanced at the opposite lineup, and saluted the white-bearded elder in the middle.

Zheng Xuan nodded his head slightly, his eyes revealed the wisdom and kindness of the elder, he looked him up and down, and said in a deep voice:

"Please take a seat."

"Please!"

Cheng Yuanzhi glanced at the seat opposite to Zheng Xuan's lower head, surrounded by people, very much like the seat where a prisoner is being tried.He quickly fanned the folding fan in his hand, and decided to stand and talk.

"Duke Zheng, let's start!"

Zheng Xuan nodded: "The first question: Today there are chickens and rabbits in the same cage, with 35 heads on the top and 94 feet on the bottom. May I ask how many chickens and rabbits are there?"

Chicken and rabbit in the same cage?

So simple?
Cheng Yuanzhi was taken aback, and blurted out: "Rabbit 12, chicken 23."

Fast, too fast!
Everyone was in an uproar and looked at each other.

Before today, they had never seen anyone who counted so quickly.

Cheng Yuanzhi was silent. The world knows "Sun Tzu's Art of War", but Sun Tzu also had a great arithmetic work "Sun Tzu's Mathematical Classics".

This chicken and rabbit in the same cage is the arithmetic problem recorded in it, and it is also the ancestor of all the "chicken and rabbit in the same cage" problems handed down to later generations.

Zheng Xuan actually used this question to test him?

In later generations, this kind of question is bad, and his grandma can do it.

Yes, from the perspective of later generations, there are many ways to solve this problem, but at this time, there was no era of multiplication and division. You could only rely on counting the numbers with your fingers, or adding and subtracting chips (small bamboo sticks).

Thinking of this, Cheng Yuanzhi was relieved, and his expression calmed down. Discussing arithmetic with Zheng Xuan was already a dimensionality reduction blow, and there was nothing to be proud of.

Zheng Xuan stared at Cheng Yuanzhi in surprise for a while, then raised his hand to indicate that it was his turn to ask the question.

"There is a number, 3 numbers of 3 lands, and 1 is left at the end; 6 numbers of 6 lands, and 4 is left at the end; 9 numbers of 9 lands, and 7 is left at the end, what is this number?"

Cheng Yuanzhi picked a relatively simple question. After finishing speaking, he did not just sit down, but started to walk in the hall with his hands behind his back.

At this moment, all the people in the hall who knew a little about arithmetic frowned, and couldn't stop doing mental calculations.

Inhalation sounds one after another.

wrong.

Still not right!

Zheng Xuan thought for a while, ruled out several numbers one after another, picked up the chips and put them up.

After about a cup of tea, he whispered, "Yes."

"This number equals seventy."

Cheng Yuanzhi nodded, the answer is correct.

Zheng Xuan thought for a while, decided not to be entangled in mental arithmetic, and changed the question:
"This Dongcheng tea house rises from the ground. How can I measure its height for one person per foot?"

While speaking, everyone came outside the tea house, facing the sun, and answered on the spot.

Cheng Yuanzhi looked up at the three-story wooden building in front of him, smiled slightly, drew out his long sword and stuck it on the ground, pointed at the shadow cast on the ground and said:

"Use this sword as the standard. When the length of the shadow is equal to the body of the sword, measure the length of the shadow of the building, and you will know the height of the building."

As soon as this remark came out, the audience suddenly fell silent.

Some people were thinking, some people were stupefied, Zheng Xuan suddenly sighed: "Wonderful, wonderful!"

Behind Zheng Xuan, everyone quickly whispered to each other, asking each other where the magic is.

It was Cheng Yuanzhi's turn to pose a question.

Everyone watched excitedly, and did not go back to the house, they all looked over expectantly to see what problems he could solve.

"It is known that a giant elephant is one foot tall and two feet long. How can I measure its weight?"

"This……"

How do you measure the weight of such a big guy?

Zheng Xuan looked at the people around him. He didn't ask for advice, but felt that this question was more difficult.

Obviously, killing an elephant to measure its weight is not an option. When the blood bleeds all over the place, the weight will be difficult to calculate.

Is there a way to hang an elephant without breaking it down?
No, an elephant is so big, who can lift it?
Even if it can be lifted, there is not such a big weight in the world.

Then change your mind...

.........

In this way, Cheng Yuanzhi waited until dark, and no one thought of a solution.

"The true explanation of this is stored in the Shangdang County Governor's Mansion. If you are interested, you can go to the Shangdang party. At that time, the prefect Zhang Yang will definitely sweep the couch to welcome you."

After leaving these words, Cheng Yuanzhi drifted away.

The bait has been cast, it depends on how many people Old Zheng will bring to Shangdang this time.

Well, after these people have gone, immediately arrange for them to be "teacher", "treasurer official", "long history", "master book" and so on...

People must give full play to their talents, and they cannot be left idle.

Well, two more difficult math problems have to be hung on the prefect's mansion, and it is stated that whoever solves the problem can leave at any time.

If you can't answer...

Then stay and work.

Ha ha…

As the sky darkened, outside the Dongcheng Teahouse, everyone gathered together, still thinking.

How does a giant elephant bear the weight? The extended problem is how to accurately calculate its weight when encountering a giant; how to quickly measure the grain in a full warehouse when patrolling a place.

In addition, Zheng Xuan also thought of a problem: the person who wrote the question must have already crossed the arithmetic problem of weighing a giant and entered a new realm.

So what is the other party's current state of arithmetic?
This made Zheng Xuan's thirst for knowledge, which had been extinguished for a long time, suddenly become intense.

There is no doubt that this is the direction he will seek in the future.

He originally thought that his arithmetic was invincible in the world, but he didn't expect someone to be better than him. Where did this guy learn it?
Shangdang County... Do you want to go and have a look?
Go and see if you won't be detained there as a long-term worker...

This Shangdang prefect Zhang Yang is very evil, should I take some precautions?

Although Zheng Xuan still wanted to continue thinking, he couldn't stand it anymore. Excessive use of his brain for a day made his head drowsy.

After all, a 60-year-old is not young anymore.

Zheng Xuan waved the crowd to disperse, returned to his mansion in the car, tilted his head on the bed, and fell into a deep sleep.

At the moment before his consciousness fell into chaos, he finally made up his mind.

Then go to Shangdang County to have a look.
