The back house of He Mansion in Chang'an.
He Chou was sitting with his clothes on. He was not in a good state of mind. He had a minor illness at the beginning of summer, which continued until now. It has been almost two months and he has not recovered well.
This is what happened when I got older, but my family was all very nervous. I invited the royal doctor from the palace and famous doctors from Chang'an one after another. The soup was so thick that I almost vomited.
Things have improved recently, and everyone in the He family has breathed a sigh of relief. However, He Chou is old and frail, and after so much trouble, his energy is greatly exhausted.
But the old man is never idle, and his curiosity is still so strong. Maybe this is the reason why he lives longer than others?
Now he is holding a simple book and reading it attentively, which shows that his eyesight is still good and his thinking is very clear. From time to time, he will pick up a pen to write and draw on the paper. Several maidservants are waiting at the side, only paying attention to him.
He doesn't disturb his every move.
I don't know how long it took, He Chou rubbed his eyes, covered his head and thought, and suddenly said: "Come here, please change my clothes, I want to go to the palace to see you."
That's right, he had been studying the pamphlet sent by Li Poren for the past few days. The content was not worth mentioning to him, but the numbers and the simplicity of the symbols made him put it down immediately after reading it.
In fact, from the Spring and Autumn Period and the Warring States Period to the Sui Dynasty, in these more than a thousand years, the study of arithmetic has made great progress. Today, the nine chapters of arithmetic taught in the Imperial College and Chang'an Academy range from the most basic four arithmetic operations to solving equations.
Then to plane geometry, everything is covered, and even the Pythagorean theorem is clearly understood.
Moreover, it is called the science of numerology, and its application has been promoted to a certain extent. However, many people do not do their job properly and use them to tell fortunes, which is a bit nondescript.
The later scholar-officials went even further. Because they did not want to spend every penny, they gradually put the study of arithmetic into the category of inferior studies. They only focused on the Four Books and Five Classics, and all other things became extracurricular readings.
Just read it, if you are not interested it will not hinder your future.
At that time, arithmetic was still one of the orthodox schools in the world, and students from various schools were taught whether they were proficient in the nine chapters of arithmetic or not, but almost all of them were compulsory subjects.
Therefore, in He Chou's eyes, the primary school reading materials produced by Li Po were not very exciting. The only redeeming feature was the way of expression.
Using exquisite numbers and some symbols to replace pure text descriptions is obviously concise and convenient. It immediately opened a new door for the master craftsman.
In He Chou's opinion, these things are so mature that He Chou's work can be rewritten and the thickness can be reduced by half.
Because the nine-chapter arithmetic had a great influence on people in the world, He Chou's artifacts of the He family are also divided into nine chapters, but they focus on various applications.
In other words, only those who have studied arithmetic subjects can understand He's work, which is more like the applied subjects in university later.
If such a work is to be written into a book, the road is difficult and tortuous, and a large number of classics need to be read, because the wisdom of the predecessors can be used, but it cannot be said that it is invented by oneself, which will make knowledgeable people laugh instead of praise.
for your whims.
Therefore, when he was in Jinyang, because there was no one to consult with him and he was unable to consult previous writings, his progress was very slow on his own.
When he arrived in Chang'an, he not only had a large number of books for reference, but also Yuwen Rutong, Dou Shilun and other like-minded people participated in business with him, and the progress quickly accelerated.
Last year, Li Po took all the books in Guanwen Palace to Chang'an Academy, and He Chou was the most staunch opponent, because it caused great inconvenience for him to check the classics.
So there was a catalog of the Guanwen Palace's book collection in He's house. If he wanted to check something, he would ask someone to go to Chang'an Academy to get it. Not to mention, Li Po was really proactive and asked someone to record various items in Chang'an.
The collection of books in the library and the catalog were also sent to He's house.
After taking Luoyang, Li Po sent people to check the Guanwen Hall in the Luoyang Palace. The situation was not bad. No one was going to burn the Guanwen Hall in Luoyang, but it was not optimistic either.
The place was poorly maintained, and many of the books had traces of rats and insects, and the damage was relatively serious. Therefore, Wang Shichong, Li Mi and others were added to the list of crimes in the Sui Dynasty.
In fact, the real disaster was caused by the numerous libraries in Luoyang City. Many of them were demolished and used to make fires. Later, they were cooked by hungry people to satisfy their hunger. It can be said that there were very few survivors.
He planned to build an academy in Luoyang, so the books in the Guanwen Hall in Luoyang were not brought to Chang'an. The books there were actually no less than those in Chang'an, or even more. After all, Yang Guang had always regarded Luoyang as his hometown and loved it very much.
Almost all of the collections of books and atlases he asked people to write are hidden in the Guanwen Hall in Luoyang.
……………………
With the emperor's strong support, all kinds of conveniences came to him, and books were just one of them. Hearing that He Chou was writing a book, and that the emperor valued it so much, many people heard about it and wanted to help Master He.
He Chou was both happy and painful at the same time.
Because some people just want to be famous and don't have much talent. They are of no use to them and they still talk about it, which is very annoying.
……………………
In fact, with such manpower and material resources, and the strong support, the emergence of He's artifacts will definitely occupy a place in the long history. If the publicity is effective, it will not be a problem to establish a sect.
Li Po's promise to He Chou back then is becoming reality step by step.
Now another "wonderful book" was sent to him, which made He Chou both grateful and a little scared. If He Chou's artifacts were not as good as the emperor's wishes, then He Chou would have really failed the emperor's trust.
In other words, this matter has gradually turned from a private matter of his to one of the major national affairs. According to the emperor's wishes, it is to be included in the study of Chinese culture.
Compared with the Nine Chapters of Arithmetic, Sun Tzu's Calculation of Classics, etc., as well as the Essential Art of Qi Min that explains farming written by Jia Sixie a hundred years ago, can He's Works written by He Chou really be comparable to them?
And the name of He's artifacts should be changed? It sounds shameful to use the word "He" in front of it now... At the beginning, I just thought it was a family name, so I used my own surname in front of it.
.
But now that the scene is so big, will people later laugh at him for not overestimating his abilities?
He Chou was quite troubled. Apparently he felt great pressure when the book was about to be completed. He felt cold when summer came, which was mainly caused by anxiety.
Now he wants to go to the palace to see the emperor. In addition to really wanting to discuss the use of these things with the emperor face to face, he also wants to have a heart-to-heart talk with the emperor. What the emperor says always fills him with joy. Well, he wants to relieve his stress...
