Ten minutes later, on the way back.

Shi Chunlai and Gu Jianjun were relatively silent, and after a long while, Shi Chunlai finally couldn't help it and asked:

"So, if you study well, you can really make money?"

"Fifty thousand?"

"It's just such a thing, it's 50,000 yuan?"

"Gu Xiu is still a primary school student, so he can earn 50,000 yuan?"

Gu Jianjun was also a little dazed, and when he heard this, he subconsciously nodded, but then shook his head.

Bite one's tongue.

But in the end, he didn't say anything, just said a word to Shi Chun:

"Lao Shi, do you say that we will be eliminated by this world in the future?"

Unprecedented.

For the first time.

The two middle-aged men had such a sense of crisis in their hearts.

Because just now.

Under their witness, Gu Xiu sold the model he made later, and it was still at a high price of 50,000 yuan!

Or 50,000 yuan is not much.

Even for Gu Jianjun and Shi Chunlai, 50,000 yuan is not an astronomical amount.

But be aware.

The person who earned the 50,000 yuan was still a primary school student.

Especially when they heard that Gu Xiu had worked on that model, it only took a few days of effort.

In a few days, 50,000 yuan arrived.

The speed at which they make money is beyond their comprehension.

What makes them even more incomprehensible is that they can't understand how the money is earned, and they don't even understand what mathematical modeling is.

Such a lack of understanding brought a strong sense of crisis to the two middle-aged men.

It's as if in the next second, it will be eliminated by the world.

"Dad, Uncle Shi, how can it be as simple as you say, this 50,000 yuan is not so easy to get, I have to improve this model before I can use it directly."

"Although the general idea is fine, and the framework is no problem, if you want to use it directly, you have to optimize it."

"It's not a cheap time."

"It's going to take a while."

Gu Xiu explained, this is half-true, and it can be regarded as a preventive shot for Gu Jianjun, and then he will be fishing in the open.

Of course, Gu Jianjun and Shi Chunlai couldn't tell the difference between the true and the fake, Shi Chunlai was still shocked and modeled for money, and couldn't help asking:

"Gu Xiu, to be honest, I still don't understand, what is your mathematical modeling?"

Gu Jianjun's face was also full of curiosity, and he was obviously very strange.

"Mathematical modeling, to put it bluntly, is something that uses mathematical knowledge to build a model for practical problems and is convenient to solve."

"Generally speaking, when analyzing and studying a century's problems from a quantitative point of view, you want to study deeply, understand the information of the object, make simplified assumptions, analyze the internal laws, and express it with mathematical models."

Gu Xiu explained.

But finding that Gu Jianjun and Shi Chunlai were still full of question marks, they thought about it for a while, and said again:

"It's like my dad's restaurant."

"The number of people at the table every day varies in the morning, noon and evening, and the number of diners varies seven days a week."

"In this way, it means that in the preparation of the ingredients, it is often necessary to follow experience."

"But if there is mathematical modeling, we can build a model based on the observation of existing data."

"This model can predict the number of diners, diners' preferences, taste tendencies and other data in the future, and then buy the corresponding ingredients according to this prediction."

This easy-to-understand explanation immediately made the two of them suddenly realize.

"So there's still this thing?"

"How can this math be so useful?"

"I used to think that after finishing math in elementary school, addition, subtraction, multiplication and division would be useless, but I didn't expect it to be of such use?"

Understand at the same time.

The two couldn't help but sigh again.

Gu Jianjun was even more energetic: "Can you get me a model of this?" ”

"Absolutely." Gu Xiu nodded: "It's ......"

"What's it?"

"It's time, and generally speaking, this kind of practical modeling requires a dedicated team to complete."

"I'm alone, so I definitely have to spend more effort, and in terms of time, I may not have enough, especially since I have to go to Mr. Liang every day, and I may not have time to do this."

Gu Xiu said, and finally saw the poor dagger:

"Of course, since Dad needs it, then I'll tell Mr. Liang that I won't go to him for the time being, and I'll go back when Dad's modeling is completed!"

Modeling is a minor issue.

At least for the current Gu Xiu, it is not complicated, and it is even simpler to model a small restaurant like a gourmet guest.

But alas.

"Do you want time?"

"Forget it."

Gu Xiu's wishful thinking failed, and Gu Jianjun shook his head directly:

"It's important for you to study now, don't delay your study."

"Although the modeling you said is good, but we don't have many stores, and we didn't have this modeling before, so we can continue to do it, so I won't delay your time."

"The most important thing for you now is to study, and everything else is not important."

Gu Xiu: ......

He was tempted to say that in fact, the study was not that important.

But he didn't dare to say.

Fear of being beaten.

"Actually, it's not too much of a delay."

"I usually need to find cases to practice, Dad, when the time comes, give me a copy of the sales data and procurement data in the background of the store, and when I am fine, I will help you do it."

Gu Xiu opened his mouth and said.

No way.

After all, it's my own Lao Tzu, it's impossible for Lao Tzu to be in need, and he deliberately didn't get it for him, right?

And when Gu Jianjun heard this, he was even happier in his heart.

My own boy, it's out!

Originally, Gu Xiu also planned to help Shi Chunlai get one, but Shi Chunlai thought about it, and his monitoring company didn't seem to need this thing.

So he didn't ask Gu Xiu to help him get this, this was the time to let Gu Xiu be fine, and teach Shi Qingsong and Shi Jieyun.

Gu Xiu naturally did not refuse.

After returning home, Gu Jianjun called up the background data in the store to Gu Xiu and told him not to delay his studies.

Gu Xiu naturally agreed.

However, when he clicked on the data, Gu Xiu couldn't help but wonder:

"Dad, in the past two months, the sales in the store have fallen so much?"

"Well, it's the off-season, how can business be booming every day." Gu Jianjun replied casually:

"Moreover, now Jiangcheng is engaged in urban construction everywhere, and sometimes there will be road closures, which will affect business."

This explanation does make sense.

But Gu Xiu was still strange: "But if it declines again, it won't be cut in half, right?" ”

Yes, cut in half.

Before the Spring Festival, and even after the opening of the third store, the business of Gourmet Meike was still booming, and the business was very good, and the daily turnover easily exceeded 10,000.

It's only been a long time.

The daily turnover has been cut in half.

Even so, a few stores every month still bring Gu Jianjun tens of thousands of net profits.

But the decline is still severe.

It's even a little abnormal.

Gu Xiu asked a few more words, but Gu Jianjun didn't say more.

After coming to Jiangcheng, Gu Jianjun basically didn't talk to Gu Xiu about the things in the store.

He hoped that Gu Xiu would study without distractions.

Instead of worrying about the things of adults.

However, Gu Xiu is obviously not a child, he was actually strange before, Gu Jianjun seemed to be very anxious sometimes, but he basically didn't answer when he asked him.

And now, just by looking at the data, Gu Xiu understands.

Gourmet Beauty.

Something happened!
