Chu Tang: Tell Li Er at the beginning that I am a time traveler

Chapter 92 Just A Little Curious
Princess House.

After only one month, Li Chong and Li Lizhi got along very well.

Sharing the same bed.

Even every morning when he was going to be on duty, Li Lizhi would watch him go out.

But today Li Chong discovered an extremely serious problem.

That is, he originally planned to enjoy it after crossing.

Why is it now that he has become a social animal of Datang, and has to go on duty on time every day?

"This...what is the problem!?"

And in different scenes, he also has different names given to him by others.

In the Imperial College, others called him Li Xueshi.

In the East Palace, others call him Prince Taishi.

In the court hall, or in the Taishi Bureau, most people called him the captain-in-law.

of course……

Also in the Academy of Sciences, others generally call him the dean.

Before he knew it, there seemed to be more and more titles on him.

But if you say that you don't have these titles, it doesn't seem good.

Because in the Tang Dynasty, it was obvious that the more titles you have, the more you can prove your high status, so that the family members will not lose face when they go out.

Arrived at the Imperial College.

Someone specially helped Li Chong lead the horse to park.

Li Chong, on the other hand, stood next to a pillar and watched the doctor of Guozijian give lectures to the students.

Actually it's fine.

Anyway, most of the math problems are not a problem now that there are equations.

The one who should be troubled should be the person who made the math problem.

Mathematical problems are not easy to solve nowadays, because once the equations are solved, the difficult problems are almost invisible.

If you really do it, as long as you know how to count, you can become a teacher without using it for half a year.

And now even the calculations are saved.

This was Wang Xiaotong's decision, because this kind of reform of forgetting one's ancestors cannot be undertaken by Li Zhong.

It can be seen that Dr. Wang has also considered very far-reaching.

of course!

Mathematics is not only about calculating equations, such as calculating area, calculating volume, and calculating the distance from the sun to the earth, as well as calculating the height of mountains and the depth of valleys, all of which must be learned.

And it would be better to say that these are the most frequently encountered in real life.

This required Li Chong to see if he could improve it further.

then……

The students of Guozijian have to learn a lot of letters.

Such as area s, height h, and some common names also need to be changed.

In the past, 'wideness' was used to represent 'length and width', but now length and width are directly used.

Moreover, regarding the area, various calculations are not very unified, and Li Chong thinks that these should be abstracted and unified.

In order to allow students to use it more proficiently, Li Zhong had to combine reality and compile teaching materials.

In the case of going deep into the grassroots and collecting materials from various sources, I finally compiled an easy-to-understand arithmetic with pictures and texts. The name is...

Hugging Li Lizhi in her arms, her arms filled with the fragrance of a girl, she asked, "By the way, the princess thinks... what should be the name of this textbook?"

Shameless, just use "Li Chong Suan Jing".

But Li Chong didn't do this, which proves that Li Chong still has face.

Li Lizhi looked at so many pictures, and compared with other ancient books that are obscure and generally only have text, they are obviously very different. She also said meekly and demurely: "The name should be related to these pictures, right?"

Then Li Chong wrote down casually, "Area and Volume Calculation of Commonly Used Figures".

It's still not that accurate, but...

As long as he adds a schedule at the end, it should be almost done.

At last……

The title of the book becomes "Area, Volume Calculation and Practical Application of Commonly Used Figures".

As soon as this book comes out.

Those officials at the bottom who specialize in measuring the acres of fields and calculating the earthwork were shocked.

Because you have made calculations so simple and easy to understand, how can we make ends meet in the future?
The book is completed, and after review, there is no problem.

At last……

It is printed and distributed.

It is said that the engraving and printing technique existed in the Tang Dynasty, which is indeed good, but the scope of application is still very small.

So when Li Zhong proposed to carry out block printing, Li Er also questioned whether it was necessary to do so.

Because of the importance of books.

There should be many books that are much more important than his book.

However, none of those books said that woodblock printing should be carried out.

Moreover, this will increase the expenditure of the court.

"Do you think this is necessary?"

Li Er asked Li Chong.

Li Chong felt that this was still necessary.

After pondering for a moment, he said, "Yes!"

Li Er arranged for someone to print for him.

Fortunately, the content of this book is not much compared to other books.

therefore……

Even if it is printed in thousands of copies, it is still acceptable.

After printing.

It is a matter of distribution.

Students and doctors of the Imperial College must have a copy.

As for the rest...

To be honest, it's really not that good.

finally……

Li Chong can only take it. If he is willing to come and get it, he can come and get it.

After all, not everyone needs this kind of book.

of course!

No matter what kind of book it is, for some people who like to collect books, it is still a book worth collecting.

For example, Li Tai asked Li Zhong for a copy.

Although he was not aware of the contents of the book, it did not affect his determination to add another book to his library.

In the courtyard of the Princess Mansion.

The time is midsummer.

The courtyard is wooded and lush.

Maybe it was to return the gift to Li Chong, but to be honest, Li Tai didn't know what Li Chong liked, except for beautiful women.

But now that Li Chong is his younger sister's son-in-law, it is definitely not acceptable to give Li Chong a beautiful woman.

Then Li Tai could only pick a few tribute ink from the best place that his father gave him, and then gave it to Li Chong.

"It's a small gift, I hope the son-in-law won't despise it."

To be honest, Li Chong didn't have high requirements for things like ink at the beginning, but now, he gradually felt that some ink was just a kind of enjoyment for him to use.

Therefore, Li Tai's gift was naturally accepted on the spot.

He smiled and replied: "How can I dislike it, but the King of Yue is too polite, isn't it just a book, as for giving such a big gift in return."

"Cough! The main reason is that this king still wants to ask his son-in-law for advice."

Li Chong said: "The king of Yue has never learned those symbols and numbers, so he can't understand them. This is normal. If there is anything the king of Yue doesn't understand, you can ask me directly. I will definitely know everything."

"This king is not referring to this matter."

Li Tai said quickly.

"This king refers to the matter that the son-in-law told this king before."

Li Chong just said: "Which one?" Then, he seemed to understand it in an instant.

"At the beginning, what did the concubine's words mean?" Seeing that he seemed to understand, Li Tai continued to ask.

Li Chong also asked him, "Why did King Yue suddenly think of asking this?"

This……

What do you want Li Tai to say.

He can't say that he has a little heartbeat.

But more, in fact, still doubts.

Then Li Tai said seriously: "I'm just a little curious."
