After packing his things, Wang Can exhaled heavily, took out the brocade handkerchief and wiped the sweat on his forehead, and said happily: "Finally, I'm done... Jianzhi, you really don't plan to go to my house."
What? It’s only a month, you can go to my house and have some fun!”
"No, no need."
Shaking his head, Zhang Jianzhi said with a smile: "Thank you for the invitation... give my regards to your parents. I have other arrangements for this wedding leave, and my relatives in Chang'an also have to go out and about."
"...That's fine."
After being declined by his friend again, Wang Can stopped insisting. He knew that Zhang Jianzhi had relatives in Chang'an, and they were very close friends, so there was no reason to spend the holiday at home even if he didn't go home.
It was a little regretful, but Wang Can was already homesick for his family at this time.
His home is only more than two hundred miles away from Chang'an, but with the current road and traffic conditions, even the fastest horse cannot go back and forth in one day, so it is definitely impossible to go back during the ten-day holiday, and we can only wait.
There are two long holidays every year. For the students of the Imperial College, there are only two long holidays in a year. One is the field holiday in May when farming is busy, and the other is the dressing holiday when winter clothes are coming. If you don’t
It will be more than half a year before I can go back.
So as soon as the things were packed, Wang Can couldn't sit still.
His family sent a servant to pick him up, and he is waiting outside right now. Moreover, it is still early in the morning. If he leaves the city, he can find a place to stay before dark, and he can get home tomorrow afternoon. But if he leaves later, he will be delayed on the road.
If the delay is severe, it might not be until the day after tomorrow that we get home.
But just when Wang Can was about to say hello and leave, he suddenly saw what Zhang Jianzhi was writing at his desk. He raised his eyebrows and said with a smile: "Why? Are you still reading your math? Don't you know all these things?"
Have you read it many times?"
"Haha, let's think about it again."
Smiling slightly, Zhang Jianzhi said lightly.
In response to this, Wang Can could only shake his head and said helplessly: "You, you are too obsessed with this thing... You are not a mathematician. Wouldn't it be great if you could use these Tianzhu numbers to do some calculations?
Why so deep?"
These days, Wang Can also learned some mathematics from Zhang Jianzhi.
It doesn’t matter how deep you learn it, but because you already have the foundation of arithmetic, after you have thoroughly mastered the Tianzhu numbers with the help of your friends, there is no problem with simple addition, subtraction, multiplication and division, and you can do it in minutes.
But when he studied further, Wang Can lost any interest.
Again, arithmetic is something that only junior officials need to learn in depth. For promising students like them, it is enough to be able to understand and do simple calculations.
It is really difficult for Wang Can to understand Zhang Jianzhi's obsession.
only……
Looking at the paper and pen that Zhang Jianzhi was using, Wang Can was really envious!
According to Zhang Jianzhi, the willow branch charcoal pen was made by the Prince of Han's Palace. It is simple and convenient to use and can display words directly on the paper without using humor. There is nothing to envy about this thing. Even if it was given to Wang Can, he would not be surprised.
Use it, because apart from writing fast and writing small words, there is nothing to praise at all.
But the white paper under the tip makes me drool just by looking at it!
This was his first time meeting the famous Han Wangzhi!
In fact, not to mention Wang Can, who is just a little imperial student. I heard that Confucius, the minister of the Imperial Academy, lamented many times in public, saying that after using Hanwang paper once, he never wanted to use other paper again!
Unfortunately, this item is extremely rare, and you may not be able to get one for a long time.
As a result, my good friend Zhang Jianzhi now uses a notebook made of Korean paper!
It's not too thick, about 180 pages.
Anyway, every time he saw Zhang Jianzhi writing and drawing in this notebook, Wang Can felt heartbroken - such a good paper was used to write down those arithmetic formulas. Isn't it a waste of resources?
It's a pity that Zhang Jianzhi said that the king gave him pen and paper just to encourage him to study mathematics. If he uses it for other purposes, it would be a dishonest act and must not be done...
Seeing his friend's expression, Zhang Jianzhi didn't care. He just smiled and said, "If you are interested, just read more. Anyway, there is time outside of schoolwork. Instead of sitting around, it is better to study more."
"..."
Upon hearing this, Wang Can immediately became silent.
There is really no comparison between this person and others, it would really make people angry to death!
Obviously they all have the same teacher and the same books, but every time after the ten-day and monthly exams, Zhang Jianzhi is always one of the top ones, and Wang Can is always the one who fails.
One of the first batch! And this is because Wang Can is very attentive and Zhang Jianzhi spends a lot of time on mathematics!
When he thought of this, he felt a little upset.
Feeling overwhelmed, Wang Can was no longer interested in spending time with Zhang Jianzhi, and shouted directly to the door: "Xiao Liu, come in and move things!"
"Yes, Erlang."
While talking, Xiaoliu from home walked in, saluted respectfully and started to help his second son with his luggage.
With this little effort, Wang Can glanced at his friend: "Jianzhi, since you like mathematics so much, why don't you just take advantage of the leave to visit King Han? I see that he sends you some new information from time to time.
What you write should be very important to you!"
"..."
Zhang Jianzhi frowned and said nothing.
Of course he understood what his friend meant. In fact, if it were any other person, Zhang Jianzhi would have paid a visit long ago.
But the other party was a prince, so he was a little scared.
Although Zhang Jianzhi was very timid when he went to see Li Yuanjia last time, and spoke very freely without being humble or arrogant, but in fact it would be a bit nonsense to say that he was really calm in his heart. Especially after Zhang Jianzhi came back, he went out to find him.
People inquired about King Han's situation and learned many, many things related to him...
The more Zhang Jianzhi knew, the more afraid he became.
It's not that he was afraid of the identity of King Han Li Yuanjia. After all, he was really kind and did not look down on him because of his identity and age. Instead, he was extremely supportive of his desire to learn mathematics! Not only did he give him a set of books,
They also gave away extremely precious Hanwang paper, and even had people come to deliver newly written mathematics twice...
What Zhang Jianzhi is afraid of is not the person King Han, but the things he knows!
Mathematics makes me obsessed with it. What if it is a method that can double the production of overturned cars? And the glass that makes people dizzy, and the movable type printing that makes people stunned, will I become obsessed with it one after another?
Zhang Jianzhi knows himself too well, and he will never be able to resist these temptations.
But now if there is only mathematics, I can still keep my studies by working hard. If I learn more things...
"……talk later."
After being stunned for a moment, Zhang Jianzhi sighed slightly and said, "Why aren't you leaving yet? If it were any later, you might really have to walk on the road for three days..."
