The rural economy in ancient times was a natural self-sufficient economy.

A village is a mature economy. If you don't need salt, you don't need to communicate with the outside world if you don't need salt, and even if you need salt and iron, you only need it once for a long time.

The Wubao economy formed by the wealthy families is an independent economy, and all the resources needed inside can be produced by themselves. As long as a peasant is attached to a dock fort, he can completely ignore the imperial court.

Sunrise,

daily income,

Sink a well and drink,

What is Dili to me?

This is a true portrayal of what Zhou Yi has seen and heard along the way.

There is a saying in historiography that in ancient times, "imperial power did not go to the countryside", that is, the emperor's bureaucratic system could not manage the lowest level of society, and the management level of the bureaucratic organization at that time could only deal with things at the county level, and then down the society itself was governed.

It can also be reflected in the grade of officials in ancient times, and the officials of Jiupin County only entered the grade of the bureaucratic system.

The Cai family naturally also has a dock fort, and there are many farmers who are attached to the Cai family around, and within a radius of several hundred miles, the Cai family is like a soil emperor. Cai Yong's return also made the Cai family's prestige skyrocket, especially after Cai Yong decided to give a lecture.

It seems that the great Confucians like to lecture, Lu Zhi has lectured in his hometown in Youzhou, Gongsun Zhan, and Liu Bei have all listened to Lu Zhi's classes. In fact, Zhou Yiting admires these great Confucian scholars, these lectures are all voluntary labor, not restrained, there is no class, anyone can come to listen to the lectures. On the one hand, it is to inherit and disseminate its own doctrine, and on the other hand, it also contributes to local culture and education.

China's scholars and literati, or the elite, have a certain social responsibility and are obliged to make their own contributions to local development. If you have money, you will have the power to contribute, and if you have culture, you will get culture. Therefore, there are those who build bridges and pave roads, those who help the weak and the poor, and those who give lectures.

Cai Yong's lecture this time is partly due to Zhou Yi's credit, Cai Yong intends to pass on what he has learned to Zhou Yi, Zhou Yi only shook his head when he heard it: I have more important things to do, you should always find someone else. Of course, the words can't be said so bluntly, Zhou Yi just shirked and said: The ambition is not here!

Weng and his son-in-law almost stiffened their relationship because of this incident, until Zhou Yi said that there was a way to print Cai Yong's books in batches and let those who came to listen to the lecture have a copy. Cai Yongcai has a good face for Zhou Yi.

The cost of knowledge dissemination in this era is very high, although Cai Lun improved papermaking, but the main carrier of knowledge transmission is still bamboo slips, wooden desolation. More valuable things may be written on silk silk, but the higher cost is not conducive to widespread use.

Zhou Yi has always had the idea of experimenting with printing, which can greatly reduce the cost of knowledge dissemination. At this time, the population of the Eastern Han Dynasty was about 60 or 70 million, and it had the advantage of human resources compared with any other place or country in the world. But a large number of people are idle, the population is confined to land, and human resources are seriously wasted.

If you want to activate the huge human resources, you can only rely on education, rely on the wide dissemination of knowledge, and if you want the majority of people to get educational opportunities, the cost of education must become very low. As an important carrier of knowledge, books are one of the main resources of education.

If you can print books in batches using printing, that's a perfect solution.

Paper Cailun has already been made, but it is only a question of whether it is suitable for printing, and it is not suitable for improvement in the spirit of experimentation until it can be printed. So Zhou Yi's hard days are here again, fortunately this is the Cai family, whatever you want, as long as there are things in this era, you can get them, which brings great convenience to Zhou Yi's experiment.

When creating an invention, the most feared thing is that the technical route is immature and useless. If you invest a lot of manpower and material resources and end up going in the wrong direction, you will never get the desired result.

These problems do not exist here in Zhou Yi, everything is under control, and the basic conditions are already in place, but they are just a kick away.

After two months of hard work by Zhou Yi and the craftsmen, a page of paper that Zhou Yi was satisfied with was finally printed.

Cai Yan rewarded every craftsman as the main mother, and as a cultural person, Cai Yan certainly knew the importance of this page.

This is a moment to create history, looking at the man with a halo in his house, Cai Yan's eyes flashed in addition to worship or worship.

After consulting Cai Yong's opinion, Zhou Yi decided to print the book "Spring and Autumn", "The Legend of the Ram in the Spring and Autumn Period", and the most famous of the three legends of the Spring and Autumn Period in the Han Dynasty is "The Legend of the Ram", and Cai Yong decided to talk about the Legend of the Ram. Of course, the most original textbook of "Spring and Autumn" should be printed together.

Printing classic engraving printing is the best choice, the number of words in the book is not much, and the engraving can also be reprinted. And if you use the famous movable type printing, it is completely a cannon to fight mosquitoes, and it is overkill. Besides, Zhou Yi didn't study movable type printing, so he won't.

On the day the book was completed, Cai Yong held the brand-new "Spring and Autumn" with the fragrance of ink, and was almost speechless with excitement:

"Good, good, good, great......"

Even Cai Yan was excited with tears on her face.

While looking at the excited Cai Yong and enjoying the adoring gaze of Cai Meimei, Zhou Yi still enjoyed it a little.

Cai Yong couldn't wait for Zhou Yi to print out all the books in his collection, so that Zhou Yi almost vomited a mouthful of old blood, don't you know how many books your old man has? It was a huge project, and Zhou Yi didn't have the patience.

Fortunately, the technology has been passed on to the craftsmen, and Cai Yong can supervise the craftsmen by himself.

Cai Yong's lectures have spread all over the world half a year ago, and the people who can come nearby have come one after another, and Cai Yong has sent a letter to his old friend to say that the books have been printed. There are also those who are coming on the way.

Lord Cai, this is to build momentum for Zhou Yi.

Zhou Yi has been busy with printing these days, and when Zhou Yi explained the matter clearly to the craftsman and Cai Yong, he came out to take a look: good guys, there are nearly a thousand people in the few. There were so many scholars in the Eastern Han Dynasty, think about how many people there were when Confucius lectured.

There were fewer books printed, and it was difficult for people to read one copy, so they had to be reprinted. As a last resort, Zhou Yi also got started in person, and he was in a hurry.

It seems that in any era, people always have great enthusiasm for the yearning for the only, which may be the quality of this nation, studious.

It wasn't until the day before Cai Yong's scheduled lecture that Zhou Yi finished printing the book.

Other Confucian lectures, all come up and say, talk endlessly, understand or not understand all depends on understanding, that is like Lord Cai's lectures, each person comes up to give a textbook first, or something that has never been seen before.

This shocked all the students who came to listen to the lecture, including several great Confucians.
