Speaking of Dou Wen and Dou Wu, Liu Che pulled Yan Ming to the huge platform on the side with great interest. There's a sand table up there.

I saw that on the sand table, it was a topographic map of the surrounding areas of Chang'an City.

There are large roads on it, which are poured with cement.

"See, Dou Wen Dou Wu plans to pour the road with cement, saying that such a road will be more comfortable to walk. And said you told them. Liu Che said.

Yan Ming nodded and said, "The minister did tell them these things. ”

"You still have a lot of things in your head, right?" Liu Che asked with a smile.

Yan Ming nodded and said, "There are still a little things, and they have all been taught to the students of Hongyan Hall. The group of people brought back by the minister this time are all students who have traveled a long way, traveled north and south of the river, and have seen the world. As the saying goes, it is better to travel thousands of miles than to read thousands of books. It is better to travel thousands of miles than to read countless people. These 10,000 books and 10,000 miles of road, the minister has already taken them to learn and walk. There are countless people left, and His Majesty needs to help them complete it. In Hongyantang, these children have already graduated. ”

"Great. Looking at the old faces who were submissive, I felt bored. I can't wait to find an excuse to kill them. Just take this opportunity to change people. Liu Che said excitedly.

"They are newcomers and don't have any experience. All is just the content of knowledge and knowledge of various places in the Han Dynasty. After His Majesty's appointment, more training is needed. The students are handed over to His Majesty, and the ministers will cut ties with them. I won't be in touch anymore. Yan Ming said.

Liu Che was slightly stunned, he already knew that Yan Ming was afraid that he would think too much, so he couldn't help but nod again and again and said, "It's still thoughtful." That's it. In the past six months, there should be nothing to do, and you should take a good rest. Poyu and Yunzhong have grown taller, and their studies are also good, so let's go back and take a look. ”

"I want to see them, but the minister also wants to go to the northeast to see how the development is there." Yan Ming's heart has always been in the Northeast.

Liu Che said in agreement: "Go ahead, although it is bitter and cold there, you developed it single-handedly." There are not many connections between the DPRK and the Northeast, so you can go and have a look. Just don't let the winter pass, it's too cold. ”

As soon as he said this, Yan Ming and Liu Che glanced at each other and laughed tacitly.

Yan Ming returned to Maolingyi, but he was not in a hurry to go to the Northeast, and lived at home for a month. It's okay to read and play chess with the two children of Yan Poyu and Yan Yunzhong, but I am also very happy.

Yanran and Tian Xi also surrounded him, and the family was happy.

The old lady of the Yan Chen family was a little weak, and she often said that she was tired.

Yan Ming knew that she was old.

People are born to live by accident. And death is inevitable.

Yan Ming is also accustomed to life and death, and in the face of Yan Chen's increasingly thin and weakened body, Yan Ming gave up his plan to go to the Northeast this year.

He was afraid that Yan Chen's family would not survive this winter.

Although the news from the north has little contact with the imperial court, it has always kept in touch with Yan Ming.

It is said that Mo Zheng and Da Lao Chen studied day and night, and actually made a machine tool for processing iron. It's manual, but it's a big step forward.

This was all told to him by Liu Ling. In the letters, there are even drawings mailed to him by Mo Zheng and Da Lao Chen.

Looking at the drawing, Yan Ming's eyes were even a little moist.

That's infinitely close to a modern machine, of course, without the electrical system. In a way, the design of this machine has even more modern feel.

For this, Yan Ming drank a large pot of wine and was happy for several days.

Knowing that Yan Ming had no plans to go to the Northeast, Liu Che gave Yan Ming an edict.

Hongyantang still let Yanming be responsible.

Liu An, the king of Huainan, stayed behind as a deputy.

In the past few years of teaching career, Liu An, the king of Huainan, has completed most of the Huainanzi written by him as the chief editor and the disciples together. It's about to come to an end.

What has always worried Liu An is how to publish such a tome that is enough to make him famous in history. Let more people read it.

He told Yan Ming about it. It is necessary to ask Lao Xu to gather some craftsmen, engrave the word board, and then print it out one by one.

Yan Ming denied Liu An's idea.

He came up with movable type printing.

The matter of movable type printing.

However, Yan Ming did not take this matter by himself, but among the students of Hongyan Hall, he took this thing as a task and assigned it.

Sometimes, what is missing from invention is ideas.

As long as you have the idea, there are many people who will help you figure out the specific operation method.

When Yan Ming arranged this matter for half a month, someone came up with a movable type version of movable type printing. Of course, it is not the students who do it themselves, and the teachers of Hongyantang also feel that this kind of thing is a leap in the printing of books.

Even Tian Wen heard about it and came over directly to participate.

He was a papermaker and a businessman.

With a businessman's keen sense of smell, he immediately felt the huge space for movable type printing.

Although the Han Dynasty has not yet fully popularized education, people in many places have realized the importance of reading and writing.

The more people who read and write, the greater the demand for reading materials.

With movable type, it is naturally much easier to print things.

Even after the first version of movable type was successfully printed, even Emperor Liu Che heard about it.

Liu Che is also very interested in the word board printed in vivo.

He actually took the time to run from Chang'an to Maolingyi.

This is something that has not happened for many years after the death of the Empress Dowager.

Looking at the pages of the book conveniently printed in the movable type version, Liu Che couldn't help but be amazed. Asked again and again whose attention it was.

Yan Ming said that it was the result of the joint efforts of all teachers and students in Hongyantang.

Liu Che knew that it must be Yan Ming's idea, but he didn't say it.

Yan Ming suggested that Liu Che set up a news department. It can be published semi-monthly, and some newspapers on major national events can be printed and distributed.

There are many advantages of this, which can allow the people to understand the dynamics of the national court situation for the first time, and can also create a lot of income.

The main thing is that newspapers and periodicals can also be regarded as the mouthpiece of the state, speaking on behalf of the country.

Liu Che listened to it and felt very novel, so he explained to Liu An that the movable type version was finished and sent him a version.

The beginning went smoothly, but the typesetting and printing of one page at a time was also a troublesome and trivial job.

This work is busy until winter.

This winter, it was very cold.

Even if it is located in the Central Plains, it is cold and biting. Heavy snowfall is one after another.

Yan Ming didn't like such a cold day, because Yan Chen's body was getting weaker and weaker.

This year, the New Year is early.

After the Chinese New Year, Yan Chen's weak body finally couldn't resist the invasion of the cold.

The old lady went quietly.

Yan Ming was grief-stricken.

Yan Chen is the person who feels most sorry for him after he came to this world. It is a spiritual support for him in this world.
