"Well, that's it. Chen's tent room, this time it's really troublesome for you. ”

"Feng Dangjia is too polite. If this kid does something wrong on weekdays, you don't have to give me face, you can be punished. ”

"It's okay, even if young people do something wrong, they just need to change it. We haven't seen each other for so long, don't leave so soon, let's have a good chat. ”

"Whatever you want, the old man has nothing to do today anyway. Su Zhen, you go back first. Remember to come to work early tomorrow morning and don't be late. ”

"Yes, sir. The student leaves first and will come back to see you when they have time. Chi Fei bowed deeply to him.

Chen Tent waved his hand and let him go.

After finally saying goodbye to Shopkeeper Feng, Chi Fei returned to the courtyard happily.

When he walked to the courtyard, Chi Fei saw that the scholar surnamed Jian who lived in the south study was sitting on a stone slab basking in the sun.

In addition to him, the couple's son, who was only three or four years old, also played there.

I saw that the child was bending down to pick up a small ball made of bamboo strips from the ground, and then stumbled in front of Jian Shusheng with two short legs and handed the ball to him.

After the scholar took the ball, he threw the ball to the other end of the yard with a "hey".

The child immediately ran over excitedly to pick up the ball, and then stumbled back to return the ball to Jane.

After Jian Shusheng got the ball, he threw it out for the child to pick up. The two had a lot of fun.

When Chi Fei saw this picture, he couldn't help but have black lines on his face.

Big brother, are you kidding the dog?

But forget it, since the two parties are having such a good time, he is an outsider and don't meddle with it.

"Good afternoon, Mr. Jane." Chi Fei greeted him politely.

"Hello, Brother Su. Looking at the smile on your face when you came in, what good things happened? ”

"It's a good thing, I found a job."

"Congratulations, what's the job?"

"There is a cloth village accounting room, I just went to apply, and they agreed to accept me."

"You're Mr. Ledger?!" Jian Shusheng's eyes widened in surprise.

"It doesn't look like it, but that's what I do. However, I am only a newbie, and I have only been in the industry for half a year. ”

"The teenager Mr. Tent was a real eye-opener for me. Sure enough, the hero is a teenager. ”

"You've won the prize, but you're just eating."

"You are too modest, in this place in the capital, you can't even mix food without any skills. By the way, since you're the bookkeeper, do you know arithmetic? Recently, I've been reading the Sutra and I'm interested in it. ”

"In terms of arithmetic, I just know a little, so I don't dare to be ugly."

"In this way, you can help me look at this problem, I haven't thought of a solution for a long time." Jian Shusheng couldn't tell for a moment whether he was modest or really not, so he simply spread out the question he was studying on the arithmetic scripture to him.

Chi Fei had no choice but to take it and look at it, only to find out that this problem turned out to be a famous ancient math problem "chickens and rabbits in the same cage".

The original text of this question reads: "Today there are pheasants and rabbits in the same cage, with thirty-five heads on one and ninety-four feet on the bottom. ”

Translated: there is a flock of chickens and rabbits in a cage, with a total of 35 heads and 94 feet, and ask how many chickens and how many rabbits.

This problem appeared in most middle school textbooks of his time, and it was a very classic introductory problem to binary equations.

The solution is very simple, that is, let the chickens have x and the rabbits have y, and the equation is:

x + y = 35

2x + 4y =94

It is easy to calculate x=23 and y=12 with a binary equation, so there are 23 chickens and 12 rabbits.

However, there was no binary equation algorithm in this era, and it was difficult for Chi Fei to explain it to him.

However, he remembered that when the math teacher was teaching this problem, he also talked about another more interesting solution, and he thought about it for a long time before he remembered it.

After sorting out his thoughts, he said, "Mr. Jane, I have a more clever way to solve the problem, you might as well listen to it." ”

"Okay, you say, you say."

"First of all, the chicken has two legs and the rabbit has four legs, and we can assume that if the chicken lifts one foot and the rabbit lifts two feet, then there will be half less feet in the cage, which is ninety-four divided by two, which is forty-seven. At this time, in the cage, the chicken has one foot and one head, and the rabbit has two feet and one head, and the head is thirty-five in total, indicating that the extra is the number of rabbits, so you can use forty-seven to subtract thirty-five, which is equal to twelve. In other words, there are twelve. Thirty-five minus twelve equals twenty-three, that is, twenty-three chickens. ”

After thinking about it for a while, Jian Shusheng finally figured it out, and couldn't help but clap his hands very happily and said, "There is such an ingenious solution, interesting, interesting." Brother Su, I didn't expect you to be so good at arithmetic, let's discuss it more when we have time. ”

"I just happen to know this problem, arithmetic is really not good, Mr. Jane, you think highly of me."

"Alright, we're all neighbors living in the same place. Acquaintance is fate, my name is Jian Shuqi, and you can call me Brother Jian in the future. Jian Shusheng patted him on the shoulder very familiarly and said.

Chi Fei couldn't stand his enthusiasm a little, but still agreed: "Then I will call you Brother Jian in the future." My full name is Su Zhen, you can just call me by my name. ”

"Okay, Su Zhen, we'll have time to talk more in the future. I don't even have anyone to talk to here, I'm bored. ”

"Okay, we'll take care of it in the future."

"Refreshing, I like refreshing people. Su Zhen: Do you like to read scripts? I have a lot of scripts there, so you can pick whatever you like. ”

"Uh, it's okay, I've seen some before."

"That's great, I can't imagine that we are still in the same boat. Let me tell you, I've always liked to read scripts since I was a child, and now there are thousands of them. When I came out, apart from my clothes, I took the most with me. It's all my treasure, I'm afraid I'll be thrown away while I'm away. Not only do I love to watch it, but several of my cousins love to watch it too. It's just that their family is strictly controlled, and they don't dare to buy it openly, so they can only borrow it from me. ”

"Hmph, it's insulting." At this moment, a cold snort suddenly came from not far away.

The two looked over and saw that it was Fang Xiucai, who lived in the west ear room, who spoke. He walked in from the outside with a look of disdain.

Jian Shuqi is obviously not a person who can swallow his anger, so he opened directly: "I said Fang Xiucai, what are you humming, is there a boogie in your nose?" Then I have to advise you to dig it well, otherwise it will be bad to accidentally spray others. ”

The child, who had been having fun, saw the two arguing and ran home in fright.

"It's really vulgar, in vain that you dare to call yourself a reader."

"What a big hat, why do you say that others insult Sven?"

"Just with your open and closed mouth, how can a serious reader read such a thing."

Hearing the other party resist destroying what he likes like like this, Jian Shuqi couldn't help but get angry, "Who is talking about three indiscriminate things?" Some people just like to be pretentious and villainous. I don't think you look like a scholar, you can't make up your own title, right? ”

"Shaft dare! I am a talent on the list in Jing'an for 12 years, and you dare to slander me? Aren't you afraid that I'll send you to see the official?! ”

Jian Shuqi smiled, "Jing'an's twelve-year examination has been more than ten years now, but he is still a talent." What's so complacent about this? It's just a rotten Confucian. ”

"You're so daring! What are you, how dare you look down on Ben Xiucai! Fang Xiucai trembled with anger.

Jian Shuqi sneered: "You ask me who I am, let me tell you, I am the third ranked student in Jing'an in the twenty-second year, I don't know how many places you took the exam that year?" ”

"What do you say? You're also a showman, and you're still a student?! I don't believe it, it can't be! Fang Xiucai's eyes widened suddenly.

"Do you want me to show you the Xiucai papers? Or just make a bet with me that if I'm telling the truth, you'll apologize to me. If what I say is false, go ahead and report it to the police. I still know what the consequences of pretending to be a person of merit and fame. ”

"You ......"

"What are you, if you have a kind, you will gamble and see who will be the grandson in the end."

"Too lazy to bother with people like you." Fang Xiucai, who was white-faced, brushed his sleeves away, but walked a little embarrassed.

"Tsk, it's not interesting to be cowardly so soon." Jian Shuqi pouted.

"Brother Jane, are you really a showman?" Chi Fei couldn't help but ask.

"Of course it's true. Those who pretend to be famous are sentenced to more than five years' imprisonment at the lightest and beheading. I'm not stupid, how could I tell such a lie. ”

"Since you're a native of the capital, why did you move here?" Chi Fei could see that the brightly dressed and extravagant Jian Shuqi was not a poor talent like Fang Xiucai, and he should not move to this kind of place. Even if you really want to move out, you should at least rent a small independent building.

"It's a long story, but I'm here to keep my whereabouts from being discovered."

Obviously, the other party didn't want to say the details, so Chi Fei didn't ask any further.

Jian Shuqi was still a little angry, and scolded: "I was originally in a good mood, but I forced this rotten Confucian to destroy it." I like to read the script, what's wrong, I'm just a Xiucai who was admitted while reading the script, and I'm angry with him. ”

Chi Fei felt a little funny and agreed: "As long as it doesn't affect the business, it's normal to have some entertainment appropriately." Reading a book is already a very healthy entertainment, much better than gambling and drinking. ”

"That's right, people are not wood, how can they not have a little hobby. It is only this kind of rotten Confucianism that will regard everything other than reading as a flood beast. No wonder I still stay at the step of Xiucai after ten years of exams, I really deserve it. ”

Looking at Jian Shuqi with a vivid expression, Chi Fei felt that it was still good to be friends with this kind of love-hate person, at least he didn't have to worry about the other party suddenly stabbing you in the back one day.
