"That's an interesting statement." Li Er pinched his chin and said. When Li Er wanted to say something, he was interrupted by Li Yuan.

"I'm here to visit the academy today, but I don't want you to discuss these things in the academy, you better take these things to the morning court to discuss." Obviously, Li Yuan is not interested in this topic that he can't participate in, after all, Li Er wants to promote cement roads to the whole country, which is a national policy, and Li Yuan, an old man who has been hollowed out, doesn't care, so Li Yuan doesn't want to discuss these things in the academy.

Li Er also heard the displeasure in Li Yuan's mouth, so he didn't say much, just let Zhang Nan lead the way in front.

Zhang Nan smoothly took on the work of a tour guide.

"Okay, Your Majesty, you are now at the main gate of our Datang Royal Academy, now please come here with your ministers, and the ministers will begin to explain to you." Zhang Nan had a bad taste, and immediately thought of the rhetoric that the superior leaders of later generations came to visit the school, so Zhang Nan started.

"Your Majesty, please look to the left-hand side, the two buildings on the left-hand side are the teaching building and the comprehensive building, which are shared by the primary school and the junior high school, the primary school is on the first and second floors, and the junior high school is on the third and fourth floors. Each class is uniformly equipped with blackboards and other teaching materials, Your Majesty, do you want to go in and have a look? Zhang Nan said.

Li Er gave Zhang Nan a look to signal Zhang Nan to understand it himself, Zhang Nan also smiled and did not speak, and casually arrived at the door of a classroom, Li Yuan skillfully took out a large set of keys and opened the door of the class.

Li Yuan doesn't need to do this kind of work, but Li Yuan just likes it, every day Li Yuan likes to take a large bunch of keys, or let his personal eunuch Xia He take a large bunch of keys to wander around the campus, as if he is inspecting his private property.

For this reason, Zhang Nan also quietly gave Li Yuan a nickname behind his back, the warden of the soul lock, Li Yuan. This nickname is all because Li Yuan has a large set of keys and clanging when he walks, and he feels the same as the warden, so Zhang Nan gave Li Yuan such a nickname.

The door of the class was opened, and Li Yuan was the first to walk in, and then he stood on the podium not far from the door, and said, "Look, this is the place where I have carefully arranged teaching, if Erlang thinks there is anything wrong, he can say it." ”

When Li Er heard Li Yuan say this, he didn't answer Li Yuan's words first, but instead looked at the classroom full of characteristic socialism.

I saw that on the blackboard, there were eight large-character plaques hanging, study hard, and go up every day. And the place where the national flag should have been hung was vacated by Zhang Nan, after all, Datang has no national flag.

And the blank walls on both sides of the classroom, Zhang Nan did not let them idle, and like later generations, there were also a few plaques with famous sayings and aphorisms hanging on them.

There was only one lectern on the podium, and a box of chalk was placed on top of the podium. The layout is very simple, in fact, Zhang Nan wants to get it in the multimedia classroom that has begun to be popularized, but considering that even if he gets a multimedia classroom, there is nothing to put it, so Zhang Nan dispelled this idea.

"Well, yes, neat and generous. Some of the above famous sayings and aphorisms are also well written, where did you find Qingquan from? Li Yuan looked at the famous sayings and aphorisms that were all over the wall and asked a little strangely.

"This is all a minister's ......" Before Zhang Nan finished speaking, Li Yuan coughed dryly, and Zhang Nan immediately understood what Li Yuan meant, and then forcefully added a few words in the words just now.

"These famous sayings and aphorisms were written by the minister and the emperor together or summarized from ancient texts." Zhang Nan said.

Seeing Zhang Nan like this, Li Yuan nodded with satisfaction and said, "Well, yes, it's all from me and Qingquan's hard work." ”

Li Er also knew what little bit of Li Yuan's vanity was, and he didn't break it, but said with a smile: "Father bothered." ”

Unexpectedly, Li Yuan waved his hand indifferently and said, "Eh, for the sake of education, for the foundation of my Tang Dynasty, what if I am a little tired?" ”

As soon as Li Er saw that Li Yuan gave a pole and climbed up, he immediately stopped talking, Li Er knew that if he continued to speak, according to the degree to which Li Yuan likes to listen to good words now, then today will become Li Yuan's performance conference.

Li Er had to change the topic, pointed to the other blackboard behind him and said, "By the way, Qingquan, this thing is the blackboard." ”

Zhang Nan nodded.

"That means that the gentlemen have to write everything in class on it." Li Er continued.

"That's right." Zhang Nan continued to nod.

But why are there two blackboards? Could it be that two blackboards can still be used together? Li Er asked a little strangely.

"Ah, the emperor, you said that the back one, the back one is not used for lectures, but the blackboard in the back is used for board newspapers." Zhang Nan said with a smile.

"Board?" Li Er and Empress Eldest Sun asked in unison.

"That's right, it's a board newspaper, a board newspaper, as the name suggests, is a newspaper written on the blackboard, using chalk as a popular propaganda position for writing and painting tools, with the advantages of easy scrubbing, modification, and replacement, and some school policies can be written on it, or good people and good deeds in the class, in short, it is just a propaganda tool." Zhang Nan explained.

"Well, yes, that's a pretty innovative idea. It's just that this thing, why does it feel weird? After Li Er finished speaking, he pointed to the top of his head to study hard, and he went up eight big characters every day.

"Strange? What's weird? This is my own handwriting, is Erlang saying that my words are not good-looking? Li Yuan said.

"Ah, Erchen doesn't mean that, it's just that the blank space in the middle of these eight words is a little too much. It's going to look weird. As soon as Li Yuan heard that it was not his own problem, he pointed at Zhang Nan and said, "This guy asked to stay, and I don't know what he means." ”

After listening to Li Yuan's words, Li Er turned his head to Zhang Nan curiously, and Zhang Nan had to explain to Li Er what the national flag was.

"That place was set aside for the national flag." Zhang Nan said.

"Flags? What is Flag? Is it the flag of the country? Li Erdao.

"Yes, the national flag is a kind of iconic flag of the country, a symbol of the country, which reflects the political characteristics and historical and cultural traditions of a country through certain styles, colors and patterns. To put it simply, if we have a national flag in Datang, then as long as it is the territory of our Datang, we will definitely hang the flag of our Datang to mark that this is the boundary of our Datang. Zhang Nan said.
