"Chongpachi, you said it's unusual. What exactly is unusual?"

Queen Ma asked Zhu Yuanzhang.

Sun Cheng's words also touched Empress Ma a lot.

Originally, their bet was only based on whether Su Jing could train employees quickly and greatly improve production efficiency. But after listening to Sun Cheng's story, it was obvious that the focus was no longer on this matter.

In Su Jing's papermaking workshop, there are various systems, from production guarantee to safety guarantee to welfare guarantee.

This simply made Zhu Yuanzhang not know what to say.

"Sister, if I could go to such a workshop, would I still rebel?"

Zhu Yuanzhang did not answer Queen Ma's words, but asked instead.

Empress Ma smiled and said, "That's not possible. Then the whole world will be gone."

"Ha ha!"

Zhu Yuanzhang smiled and said: "That's true, but Su Jing's papermaking workshop is really good. He is not like any businessman I have ever seen."

From the uprising to the founding of the Ming Dynasty, Zhu Yuanzhang experienced ups and downs in his life.

Although he looked down on businessmen, he actually came into contact with many businessmen.

Without him, an uprising requires money and food.

In the late Yuan Dynasty, these things were either concentrated in the hands of officials and gentry, or in the hands of merchants.

Businessmen who are knowledgeable and far-sighted will naturally have ideas.

Zhu Yuanzhang had seen all kinds of businessmen, but he had never seen anyone like Su Jing.

"Mr. Su is a strange person, how can he be compared with those mediocre people."

Queen Ma said matter-of-factly.

Queen Ma was also shocked by the way Su Jing created the papermaking workshop.

Zhu Yuanzhang nodded and said: "Yes, if the businessmen of the Ming Dynasty can be like Su Jing, then I will be relaxed."

When he was conquering the world, Zhu Yuanzhang did not find it difficult to manage the world.

But after actually sitting in this position, he deeply felt that as an emperor, it is really difficult to manage the world well.

Therefore, Zhu Yuanzhang dealt with government affairs almost every day and never took a break.

After listening to Sun Cheng's story, it was not surprising that he had such thoughts.

Queen Ma looked at Zhu Yuanzhang and felt a little distressed.

She is the closest person to Zhu Yuanzhang and the person who knows best how busy Zhu Yuanzhang is.

"Chongba, having Mr. Su in Ming Dynasty is already a blessing to the country."

Queen Ma comforted her.

Zhu Yuanzhang shook his head and said, "Unfortunately, Su Jing has no intention of becoming an official. Otherwise, how could I just let him teach Biao'er."

Zhu Yuanzhang recognized Su Jing's talent and ability in his heart.

But Su Jing's resistance to becoming an official left Zhu Yuanzhang helpless.

Such talents must be conquered by him wholeheartedly before they can be used by him.

"Chongpachi, I don't think there's any need to worry about this."

Empress Ma said calmly: "Mr. Su is Biao'er's teacher. When Biao'er inherits the throne in the future and gives Mr. Su the position of national teacher, even if Mr. Su does not become an official, what is the difference between becoming an official?"

Ming Dynasty Imperial Master!

As soon as Empress Ma said these words, Zhu Yuanzhang's expression suddenly changed, he nodded and said: "Sister, what you said makes sense!"

"Su Jing is still young anyway. After Biao'er inherits the throne, he can still be used by Biao'er."

Zhu Yuanzhang had not changed his mind before, always thinking that he would use Su Jing now.

Now after listening to Queen Ma's guidance, I suddenly felt refreshed.

"I see that you are usually too tired. You have to remember this little thing about the bet you made with me. Can you not worry about it?"

Empress Ma complained a little, but she was also concerned about Zhu Yuanzhang.

Zhu Yuanzhang said with a smile: "Speaking of this, sister, don't mention it. Biao'er is right. Su Jing's production optimization process is really useful."

"Are you so happy after losing? I really can't understand you."

Empress Ma shook her head slightly, really not knowing what to say about Zhu Yuanzhang.

Zhu Yuanzhang said: "According to what the standard said, Su Jing's production optimization can also be used in some work of the Ministry of Industry. That is a great good thing. How can I not be happy?"

"Yes, yes, this is a great thing."

Empress Ma agreed: "But don't do these little things yourself. It's not necessary. Just leave it to the people below."

It's not that Queen Ma talks too much, but that Zhu Yuanzhang really wants to do everything by himself.

Now Zhu Yuanzhang is the emperor of the Ming Dynasty. There is really no need to do some small things by himself.

"I know, I know, I'll let the Minister of Industry do it."

Zhu Yuanzhang immediately agreed.

He would only listen to Queen Ma's advice so quickly.

"It's good to know."

Empress Ma nodded with satisfaction and added, "I don't know how Biao'er and Tie'er are doing. The weather has been a lot colder recently. You should remember to put on more clothes."

As a mother, Queen Ma still cares about her two sons who are away from home.

Especially Zhu Rui, who is so young.

Zhu Yuanzhang said: "There is nothing to worry about. Biao'er will naturally take care of Lao Wu. But I haven't written back for some days, and I don't know what I learned."

Zhu Yuanzhang has always been strict with his son's education.

What he cared about was what Zhu Biao and Zhu Ru had learned.

"You are really big-hearted."

Queen Ma rolled her eyes at Zhu Yuanzhang and said, "I'm not that cruel. I have to find time to see them."

Zhu Yuanzhang immediately explained: "Sister, I'm just talking casually, don't worry about it."

Here in Lishui County.

Su Jing taught Zhu Biao and Zhu Ru as usual.

After a brief chat about corvee labor and public facilities, Su Jing's main focus was on Zhu Rui's mathematics study.

"Master Su, I have solved this linear equation of two variables. Please see if it is correct."

Zhu Xi said to Su Jing.

"Okay, let me take a look."

Su Jing immediately looked at Zhu Xi's steps to solve the problem.

Very detailed and careful.

"Well, very good, there are no errors or omissions. You have mastered the linear equation of two variables quite well."

Su Jing nodded with satisfaction.

He is very satisfied with Zhu Ju's learning progress.

In just over a month, I have mastered the solution to linear equations of two variables.

Many mathematical concepts involved are also clearly understood.

First, Zhu Rui's mind is really smart and his thinking is clear. Second, he is really hardworking and serious enough.

"It's all taught well by Master Su."

Zhu Xi said modestly, except that he looked like a nine-year-old child, there was nothing else about him that looked like a nine-year-old child.

Su Jing smiled and said: "Humility is a virtue, but it is not necessary to go too far. Niu Su, today I will teach you something different."

"Please also ask Master Su to teach me."

Zhu Ru immediately straightened his body and listened carefully.

At this time, Su Jing took out a copper plate and put it in the palm of her hand, then threw it directly upward, and then fell into the palm of her hand.

"Here, guess what, is it positive or negative?"

Su Jing asked.

Zhu Ru thought for a while and replied: "Front."

Su Jing opened her hand, showing the front.

"Yes, the answer is correct, but there is no reward."

Su Jing continued to throw the copper plate upwards and caught it, then asked: "Keep guessing, what about this time?"

"Still positive."

Zhu Rui replied.

Su Jing opened her hand: "It's wrong, it's the opposite, but it doesn't matter. There is no punishment for being wrong."

After two times, Su Jing did not continue to toss the copper plate, but looked at Zhu Ru and said: "If I continue to toss ten times, how many times do you think it will be heads and how many times will it be tails?"

Continue ten times?

Zhu Jing thought about Su Jing's question and did not answer immediately.

Su Jing said: "Don't think so much, just answer with your intuition."

Zhu Rui nodded and said: "Master Su, students think it should be heads five times and tails five times."

"very good."

Su Jing nodded. He was very satisfied with Zhu Xi's answer to this probability question.

Although for Zhu Ru now, he doesn't know what probability is.

"Then let's try and see if that's the case."

Su Jing tossed the coins one after another and asked Zhu Xi to record the results. The final result made him look a little surprised.

"Master Su, three times heads, seven times tails."

Zhu Ru looked at the result blankly, a little surprised.

This was far from his intuition.

"Why, do you feel like something is wrong?"

Su Jing said with a smile.

Zhu Zhu nodded and said, "The student guessed wrong just now, but the student doesn't know why he guessed wrong."

"You toss it ten times and see the result."

Su Jing threw the copper plate to Zhu Ji.

Zhu Ru nodded and immediately started the experiment.

Soon, he had ten results: eight heads and two tails.

At this time, Zhu Xi couldn't understand it again. There was such a big gap between the two results.

"Keep throwing, eight or ten more times, record all the results, and sum them up with these twenty times."

Su Jing said to Zhu Xi.

If it were in a math class in a previous life, it would probably only be done by throwing it a dozen times.

That's because the accurate conclusion has already been reached at that time, and there is no need to discuss it further. The teaching must be advanced as soon as possible.

But now, Zhu Xi's understanding of probability is still at an ignorant stage.

The best way to understand probability is to do this experiment several times honestly.

Zhu Tie was also quite obedient. He tossed it eighty times and recorded the results one by one.

"Master Su, I'm done. The result of one hundred times is 58 heads and 42 tails."

Zhu Xi said to Su Jing.

Su Jing nodded and said: "Niu Su, have you noticed? As the number of times you throw it increases, the number of times the heads and tails appear is getting closer and closer."

"Isn't it even closer to the 50-50 split you answered before?"

"If you continue running, a thousand times, or even ten thousand times, what do you think the number of heads and tails will be?"

Su Jing slowly guided Zhu Ru.

Zhu Jing also listened to Su Jing's words carefully and thought about Su Jing's question. He replied: "It should be getting closer and closer."

"very good!"

Su Jing looked at Zhu Ji and said: "When a copper plate falls and appears heads and tails, it is a random event. It is possible for heads and tails to appear. We call this possibility probability. The size of the probability is the size of the possibility. .”

A strenuous operation was just to introduce the concept of probability to Zhu Rui.

Although Su Jing wanted Zhu Ru to master it quickly, he knew that haste makes waste.

Only when Zhu Ju truly understands it can he continue with the following teaching.

"Master Su, students understand."

Zhu Ru thought carefully for a while and answered this time.

Su Jing then took out another dice and began to repeat the same experiment, but this time, the possible results became six.

Repeat throwing, repeat recording.

This is a rather boring process, but Su Jing has been doing it very seriously, and he must convey this attitude to Zhu Ju.

This is the founder who will bear the important responsibility of future scientific research, and rigor and seriousness are a must.

Fortunately, Zhu Ru didn't show any impatience at all and was doing experiments with Su Jing seriously.

The study of probability is a very important tool for future exploration of the laws of genetics.

When Zhu Ru was studying with Su Jing.

Zhu Biao was caught up in the search.

Su Jing told him a lot of things during this period, and in Zhu Biao's eyes, they were all good strategies for governing the country.

But there is still a distance between Su Jing's theory and its actual implementation in the Ming Dynasty.

His current idea is to shorten this distance.

However, it is still too difficult for Zhu Biao to work behind closed doors.
