Wei Renshi wants to go back to Luoyang, but now he is not so free.

When the nobles left the fiefdom, they had to report to the imperial court. Although this is just a formality, there is a real homework in the Chongwen Pavilion, not only do you need to take leave with the bachelor of the Chongwen Pavilion, but also those who have a title like Wei Renshi also need to take leave with the prince.

Because the other students are just students, but Wei Renshi has a knighthood, so he has a layer of subordinate status in addition to the students.

But the prince didn't appear in the Chongwen Pavilion in three days, and Wei Renshi was not a substantive official of the East Palace, so he couldn't take the initiative to visit the prince.

You can only wait for when the prince appears in the Chongwen Pavilion again before you can take leave from the prince.

I can only continue to stay up in the Chongwen Pavilion first.

"I said a few brothers, who is familiar with the capital and knows a lot of people, do the younger brother a favor?" After class, a few people gathered together during the break, eating the snacks brought by Wei Renshi, and listening to Wei Renshi ask.

Then they asked, "What is it?" Just talk about it. ”

"The younger brother wants to find a few craftsmen who can engrave letters, preferably one who can engrave engraving." Wei Renshi said: "I heard that there are craftsmen who know how to carve in Guozijian, but the younger brother has no way at all. ”

"Brother Renshi wants to carve a plate?" Fan Zhiyi was puzzled: "The craftsmen who know how to engraving may only be the only one in the country." ”

"Oh?" Wei Renshi hurriedly asked, "Where are there other places?" ”

"It's too much." Gu Pengju said: "Hongwen Pavilion, Chongwen Pavilion, and Jixian Hall Academy in both capitals, because they all have the responsibility of repairing books, so there will be craftsmen who know how to carve plates. We've got several! ”

"So we have it in Chongwen Pavilion?!" Wei Renshi was immediately overjoyed and said: "It's really nowhere to find the iron shoes, and it takes no effort to get it!" ”

"There is nowhere to find the iron shoes, and it takes no effort to get them...... everyone muttered, and Quan Qiaoqiu said: "Strange poetry......"

"Don't worry about that." Wei Renshi waved his hand and said, "I don't know where those craftsmen who can carve and engrav are?" ”

"It's in the annex." Quan Qiaoqiu said: "But the annex is a place for repairing books and school books, so we are not allowed to enter." If you want to go in and find a craftsman, I'm afraid you'll have to get the owner's permission. ”

Wei Ren was a little hesitant.

At this time, it is still engraving printing, printing needs to be engraved first, and the printing is very fast, but the stereotype is very slow. Moreover, if there is a single stroke of change, the whole sheet will be ruined and will have to be re-engraved, which seriously hinders the efficiency of printing and hinders the publication and dissemination of books.

Engraving is time-consuming, labor-intensive, and the storage of a large number of book plates is inconvenient, easy to rot, difficult to preserve for a long time, in addition, there are errors are not easy to correct, a little change has to be destroyed and remade. These three points are the biggest defects of engraving printing.

Bi Sheng improved the printing technique, and the emergence of movable type printing not only promoted the development of the printing industry, but also promoted the dissemination of books, and made great contributions to the dissemination and preservation of Chinese cultural classics.

Even after it was later introduced to the West, it directly contributed to the Renaissance in the West.

Movable type printing is Bi Sheng's invention and the pride of the Chinese people.

Just empty words, may not be enough to intuitively explain the improvement of movable type printing to engraving printing. In the Song Dynasty in later generations, after Bi Sheng invented movable type printing, someone made a comparison. The "Tripitaka Sutra" printed in the Song Dynasty, a total of more than 5,000 volumes, was printed with engraving at first, a total of 130,000 wooden boards were carved, several rooms could not fit, and more than 100 craftsmen took many years to complete. Later, it was switched to movable type printing, and it took only a few months for a dozen or so people to complete it easily.

It can be seen that movable type printing has made progress compared with engraving printing.

Since the progress is so great, it must also be a great credit and a great reputation.

Wei Renshi wasn't sure if this credit and fame could fall on him.

Since there are also engraving craftsmen in Jixian Hall Academy, Wei Renshi can completely ask Bachelor Zhang to help him and follow his path. With Mr. Zhang's character and friendship with himself, he will never be greedy for his own merits, and will definitely play truthfully.

This is the safest way to do it.

But now that he is in the Chongwen Pavilion, he is considered a vassal of the East Palace.

Although there is no hard and fast rule, he must first give this method to the hall owner, and then the hall owner will give it to the prince, and the prince will play the credit. But from the perspective of human feelings, I should do this.

After thinking about it, Wei Renshi still chose the latter.

So at noon, when everyone went to eat, Wei Renshi went to the back by himself and went outside the owner's house.

After being passed on by the waiter, Wei Renshi soon met the owner of the pavilion.

"The students meet the owner." Wei Renshi saluted after entering, and then remembered that he didn't know what the surname of the bachelor in front of him was.

"Oh, what's the matter with Watson?" The owner asked.

Wei Renshi replied: "When the students first entered the Chongwen Museum, Mr. Liu asked the students to copy the textbook and use it. Now that the textbook is almost finished, the students should copy another textbook to use. It's not that students don't want to copy, but they just think about the big picture and think about the current situation of my Datang books. ”

"The current situation of Datang books?" After hearing this, the owner smiled and said, "Tell me, what is the current situation?" ”

"Although there are many students, they suffer from no books to read. Even though there are new books in the world, it is difficult to print them. Ancient books are precious and can only be transcribed and preserved, but manpower is limited, and only a few copies can be kept, which are hidden in the deep museum, which cannot be read by students all over the world. Wei Renshi replied: "The current situation of Datang books today is nothing more than these three. ”

The hall owner nodded and said, "That's not bad. But what if you think about it? ”

"If you think of it, you try to solve it." Wei Renshi said: "These three problems, in the final analysis, are still the skills of printing books. Nowadays, with engraving to print books, each book is different, so countless engravings are needed. A book often has thousands of words, and it takes a lot of time and effort for a craftsman to engrave it before it can be printed. Among them, there is a change in the book, or a word carving error, and the previous engraving plate can no longer be used at all, but can only be re-engraved. So it's slow. ”

The hall owner frowned slightly, looked at Wei Renshi, and asked, "What does Wei Sheng mean?" ”

"This problem can be solved by students." Wei Renshi said lightly.

"Oh?" The owner of the museum looked at Wei Renshi unexpectedly, smiled, and said, "What problem do you solve, the disadvantages of books in the world?" ”

Wei Renshi smiled and said: "Students have a way to solve the disadvantages of engraving printing, and in the future, printing can not need engraving." ”

"What?!" The owner of the hall looked surprised, as if he was a little unsure of what he had heard.

"The students are saying, since engraving printing is so inconvenient, why don't we adopt a more convenient method?" Wei Renshi said to him: "For example, movable type printing! ”
