The two discussed for a while, and Dou Dan stood up to leave.
They had little friendship, and there was a gap in seniority. If Dou Wei and Dou Kang were still there, they could be friends with He Chonglun, but Dou Dan obviously lacked the weight.
He Chou tried to persuade him to stay, but Dou Dan said firmly and left. He Chou asked his son to send him out of the house, and he returned to the couch and sat down safely. He drank a few sips of tea. Immediately, a maid came forward to rub him. Rub your shoulders and massage your head.
The old man's old age life was so nourishing.
It's just that there are also headaches. Dou Dan's matter is nothing to him. Anyway, he doesn't have to worry about it himself. He can just leave it to others.
Dou Dan's pettiness was clearly visible in his mind. Dou Guangda could not put aside the matters assigned by the emperor himself. Taking advantage of the opportunity of visiting, he wanted to pass it on to He Chou.
As for him, he took advantage of the situation and recommended Li Xiyu to take charge. It can be said that everyone got what they needed and everyone was happy.
He Chou is now focusing on his writings. The year before last, the "He's Gongwu" edited by him had been basically completed, and it contained a lot of content.
In addition to various crafts, there are also some things about geography, water regimes, geology, and vegetation, as well as the mining and measurement of various minerals.
Similar to later encyclopedias.
If the division is more scientific, it is an encyclopedia on various crafts and technologies such as handicrafts, construction, planting, machinery, ceramics, sulfur, weaving and dyeing, etc.
Part of it is based on the experience of previous generations, and part of it is the various craft skills introduced from outside, such as the production of colored glaze, the cultivation of grapes, etc.
He Chou's own efforts mainly focused on architecture, clay, sculpture, etc.
It took almost ten years and involved thousands of people. Especially in the past few years after entering Chang'an, he could call on people at will and the progress was greatly improved.
Anyone who is interested in this will come to his house to pay a visit without him soliciting it at all.
The emperor did not break his promise. The picture he drew for him in Jiexiu was fulfilled one by one today. It can be said that he was given the best resources without any discounts.
He Chou felt that he was very lucky, because it was hard to find a confidant. The ancients often said that a scholar would die for a confidant. In his case, it was unprecedented for a king to be able to do this for his ministers.
But He Chou was unfortunate because he was already old when he met Li Po. If he had been younger...well, that would be a bit dissatisfying.
After nearly ten years, his work on He's Works is almost completed.
But last year, the emperor came up with some knowledge about arithmetic. After He Chou calculated it, his interest greatly increased, but he had to revise his writings again.
This workload is not small, but it is necessary.
What the emperor gave is not only simple and clear, but also extremely convenient to calculate. Needless to say, He Chou's vision is that he believes that this is a science of arithmetic that can be widely used in the world.
Most of his writings are originally based on arithmetic. If it cannot be used, it will inevitably lose its luster.
So for more than a year, while urging his disciples to revise their writings, he also opened a separate volume dedicated to the study of arithmetic. It can be said that this was a helpless move, but it was also his interest. After a lot of study, He Chou seems to be many years younger, and he feels that his energy has recovered somewhat. Do you think it's strange or not?
It's basically the same as the later scientific madmen...
At the end of last year, something called the Nine-Nine Multiplication Table was passed down to him in the palace, which was similar to the Nine-Nine Song Jue of his predecessors, but more perfect.
Coupled with those concise numbers and symbols, it is like a divine help to perform basic calculations.
The information he received from the palace was partly a matter of routine, and partly it was asking him to give some questions about this thing.
He Chou knew that this was used by the emperor to teach the prince knowledge. He actually just wanted to ask the emperor face to face how much of this knowledge could be revealed, and not to show it out intermittently, causing his writing to be delayed again and again.
If he continues like this and stretches his legs, he probably won't be able to finish it.
.....................
He Chou was thinking about taking this opportunity to go to the palace to meet the emperor, but he hesitated.
He had been an official for decades, and his mind was not confused even when he was old. He could feel that the emperor was working on changing some things, and Shushu was just one of them.
Generally speaking, people who do great things have their own rhythm, and they don't want to be the one who breaks the rhythm.
For example, the numbers and symbols given to him by the emperor had been spread by him before, and many people who came to visit him would discuss the science of arithmetic for this reason.
It was obviously the emperor's intention, and it was just spread through his mouth.
The emperor did things so well that he probably wouldn't gain anything even if he went to the palace to ask questions.
Alas, He Chou sighed secretly. More and more of the mysterious features of the emperor were revealed. He didn't know who had entrusted him with the dream, but it made him so embarrassed...
While I was thinking about it, a servant came to report, "Professor Li Chunfeng of Chang'an Academy is visiting."
Li Chunfeng, a native of Yong County, Guanxi Province, was smart and studious since he was a child. A few years ago, he was recommended to serve as Li Shimin's secretary and join the army. After surrendering to the Tang Dynasty, he hid in Chang'an Academy like other former members of the Qin Palace.
Even though he is only in his twenties, he is already well-known in the literary world of Chang'an. He is proficient in arithmetic, astronomy, calendars, and can write well. He is a typical scholar-type talent.
Naturally, this was not the first time he came to He Chou's house. He had been introduced to He Chou's house before. His purpose was the same as everyone else's. He wanted to see what He Chou had done. If he could participate in it, it would be a dream.
The young man is full of ideas and has good academic skills. After the interview, He Chou readily accepted the offer.
It can be said that the book He's Works written by him is different from what he thought when he started. If he were ten or twenty years younger, he would naturally have the confidence to grasp the overall situation, and he would not call so many people.
People are around, otherwise how could he have the dignity to take full credit on the day the book is written?
Now, it's a different matter. He is too old and doesn't have the energy and time to waste. Moreover, the stall is getting bigger and bigger, so he can only use the strengths of others.
It is estimated that after the book is completed, there will be a lot of names listed in the preface above, and Li Chunfeng is one of them.
............................
Li Chunfeng came in quickly and paid homage to his disciples.
He is very good-looking, has a big face and big ears, and is very dignified. He is a very popular appearance in the world at that time. When a fortune teller sees him, he will definitely tell him about his future fortune, which means that this is inevitable.
The appearance of an official.
But in fact, as long as you have been in contact with this young man for a long time, you will know that he is lively and outspoken. He often pursues things that he is interested in and will not give up until he achieves his goal. He is quite paranoid.
