In the third year of Jianning (170 years), August, 29th.

Zhang Hao has been in this era for more than four months, and after being recognized by Zheng Xuan as his righteous son, he lived in Zheng Xuan's house with peace of mind, and today is a special day - Zheng Xuan's birthday.

Zheng Xuan is a simple person, and he seems to have nothing else to do except study knowledge, so there is no Zhang Luo on his birthday, only his family and a few friends.

"Come to Hao'er, Yi'er, I've seen your uncle and uncle, when we studied together to learn from Confucianism and Ma Rong, but I was my father's fellow brother" Zheng Xuan introduced a middle-aged man in his thirties to Zhang Hao and Zheng Yi.

This man was eight feet long and tall, and although he was dressed as a scribe, he could not hide his heroism.

"I've seen my uncle." Zhang Hao and Zheng Yi stepped forward to give a salute, and Zhang Hao pondered in his heart: Zheng Xuan's senior brother, Zigan, Zigan, Ah, Lu Zigan, Lu Zhi? Thinking of this, Zhang Hao, who was bowing down, couldn't help but lean down again.

At this time, Lu Zhi should not have entered the official career, and may still be teaching Gongsun Zan and Liu Bei in Zhuo County. However, Zhang Hao still respects Lu Zhi very much, both civil and military, upright, and does not care about power.

"And this one, for his father's year-old friend, the twentieth grandson of Sage Kong, Kong Wenju." Zhang Hao looked at a young man of about twenty.

"Uncle Wenju" Zhang Hao and Zheng Yi all gave gifts. This is the Beihai Xiangkong Beihai in the future, I didn't expect it to be so young now.

"Come, this ......" Zheng Xuan introduced several guests in turn.

"This is the righteous son Zhang Hao, and the dog Zheng Yi." After a circle of introductions, Zheng Xuan introduced Zhang Hao and Zheng Yi to everyone.

After the introduction, Zheng Xuan talked to these friends about the scriptures, and Zhang Hao and Zheng Yi ran out mysteriously.

After a while, Zhang Hao and Zheng Yi walked back with a large box.

"Father-in-law" Zhang Hao called.

"Oh? What is this? Zheng Xuan asked suspiciously. The others also gathered around, looking at the big box curiously.

"Father-in-law, this is a gift from your son and brother." Zhang Hao arched his hand and said.

Zheng Yi opened the big box, the top was a wooden board, the wooden board was neatly arranged with square grooves, Zhang Hao picked up the wooden board and put it on a few cases, revealing the things under the wooden board, small boxy wooden blocks.

Looking at everyone's puzzled expressions, Zhang Hao took out a few wooden blocks and showed them to everyone, everyone looked closely, there was a word on each square, and this word was engraved on it backwards, like a small seal.

"Father-in-law, uncles." Zhang Hao called out, picked up many wooden blocks, walked to the front of the wooden board, and placed the wooden blocks on the square groove of the wooden board, just right, one by one, and the same brush brushed ink on it.

At this time, Zheng Yi took out a piece of straw paper and spread it on it, carefully brushed it with a clean brush, brushed it two or three times, and carefully took the paper down.

"Everyone, please take a look." Following the voice, everyone looked, and the poems in a book of poetry jumped on the page.

"Ah, this ......" the crowd was shocked.

As if he didn't see it, Zhang Hao took out the wooden blocks and rearranged them, replacing some of them, while Zheng Yi repeated the action just now, and another poem appeared on the paper.

"This is a divine skill, a divine skill."

"It's magical, it's amazing."

"There is such a thing in the world."

After everyone was shocked, they all praised it, listening to these praises, Zheng Yi looked proud, and Zhang Hao looked at everyone calmly.

"Virtuous nephew......" Lu Zhi looked at Zhang Hao, and the others also looked over.

"Father-in-law, uncles." Zhang Hao arched his hand.

He continued: "The kid called it movable type printing. But I was secretly thinking in my heart: Bi Shengda, I'm sorry, I used your invention.

After a pause, he continued to explain, "Because when the righteous father gave the class a few days ago, all the senior brothers did not have a scroll, so they came up with this method, and together with my younger brother, it lasted three months, checked many classics, and made 9,353 wooden blocks without repeating single words, and made one more piece of common words, a total of 10,000 pieces, and a simple arrangement can print a large number of books. ”

"Wonderful, wonderful, the two virtuous nephews are ingenious, admire and admire" was another burst of praise.

"Virtuous nephew, after my uncle returns home, I want to order someone to imitate a set of this movable type printing, I don't know what the two virtuous nephews want." Lu Zhi looked at Zhang Hao expectantly, although he was asking the two of them, but he could see that Zheng Yi was a child, and he was looking forward to Zhang Hao.

Everyone else also looked at Zhang Hao, their eyes full of anticipation.

"Of course, all the uncles can make their own." Zhang Hao said lightly, even if there are a few people who can control themselves if they don't let the imitation, it is better to push the boat down the river and sell personal favors.

"Virtuous nephew and generous."

"Uncles, little nephews, there is one more thing, uncles can promote this technique, I hope this technique can benefit all people." Zhang Hao thought about it and said that if it can be promoted, it can give more people the opportunity to read and write.

"The virtuous nephew is broad-minded and admired by his uncle." Everyone hugged their fists one after another, looking at the six or seven-year-old Zhang Hao with admiration, and no longer looked down on him.

Zheng Xuan stood next to Zhang Hao and looked at him, smiling and nodding from time to time, not knowing what he was thinking.

"Brother Kang Cheng, your righteous son is very young, he is young and old, he has a degree of advance and retreat, he has such a talent, and he will definitely achieve something in the future." During the banquet, everyone talked about Zhang Hao again, and they all praised it.

"Congratulations to Brother Kang Cheng, you have received such a righteous son."

"Everyone laughed, haha." Although Zheng Xuan was polite to everyone, the smile on his face couldn't be contained, and Zheng Xuan didn't care about everyone not mentioning Zheng Yi.

If there is no Zhang Hao to compare, Zheng Yi is also very smart among his peers, plus Zheng Xuan has been taught since childhood, although he is not a prodigy, he is also knowledgeable, but Zhang Hao is too outstanding, and the two are together, Zheng Yi seems to be a little ordinary.

After eating, everyone dispersed, and they all wanted to fly home directly, and hurriedly found someone to imitate this 'movable type printing', and Zheng Xuan didn't keep it too much.

After the guests dispersed, Zheng Xuan also took a box of wooden blocks, and couldn't wait to return to the study, and began to experiment with 'movable type printing', printing an article and a poem, and couldn't put it down, just like a child who got a new toy.

In the following time, Zheng Xuan locked himself in the study every day except for eating and teaching, and studied movable type printing, and in less than a month, the books he printed could not fit in the study, and he had to turn an empty room into a place to store books.

Zheng Xuan's students can each have a book when they go to class, and they have more and more respect for the two "little junior brothers" who made movable type printing.
