"But we don't have any iconic flags in Datang." Li Er scratched his head and said, it is true that when the army marched and fought in the past, the word "Li" was simply written on the flag, it was the team led by the general, and the flag was the general's surname, which was convenient for command and dispatch on the battlefield.

Because the flag is basically only used when marching and fighting, after the founding of the Tang Dynasty, the people's feelings about the flag are like that, after all, it has nothing to do with themselves.

"We can design without a flag." Zhang Nan said with a smile, after all, there is an all-powerful existence of the system, let alone a flag, even ten flags and hundreds of flags can be designed.

"Design? Who will design it? It's better for me to let Yan Li draw originally. I think Yan Liben's danqing is still good. Li Erdao.

"We can discuss this thing slowly, and if we have the national flag, then we can have a flag-raising ceremony every week." Zhang Nan said with a smile.

"Flag-raising ceremony? Weekly? Li Er was now completely stunned by the new words that popped out of Zhang Nan's mouth.

"It's okay, it's okay, let's talk about this matter earlier. When the time comes, the ministers will make a detailed list, and the emperor can solve them one by one, so let's visit the school now. Zhang Nan said with a smile.

"Well, yes, I'm here to visit the academy today, Qingquan, you better take me around first." Li Erdao.

"Your Majesty, you come with the minister, and the minister is taking you to listen to the class, and then take a turn." Zhang Nan said.

"Listening to a class? What classes to take? Li Er was obviously not interested in learning knowledge.

"Your Majesty, you really don't listen?" Zhang Nan asked.

"It's not interesting, let's go for a spin if you have this time." Li Er shook his head and said.

"Eh, the emperor said so, then forget it, originally the minister still wanted you to watch Qingque's lecture." Zhang Nan said with a look of pity. As soon as he heard this son, Li Er became interested.

"Isn't the blue finch always giving lectures in the evenings? I see that he has only returned to the palace at night when he has returned to the palace recently, so why do he have to give lectures during the day. Li Er asked a little strangely.

"This is what Qingque requested, didn't you say that you wanted to visit today, Your Majesty? So Qingque advanced his class, if you want to say that you don't want to go, then the minister will take you to the complex building first. Zhang Nan said with a smile.

"Who said I don't want to attend class, I have to be a student this time. I want to see if the knowledge of the green finch has grown. Li Er said with a smile.

Zhang Nan smiled and didn't speak, in fact, the set of Li Ercliffs that Li Tai talked about now is incomprehensible. After all, now Li Tai's knowledge has begun to move towards the earth, and Comrade Li Er can't even distinguish the stones.

Under the urging of Li Er, Zhang Nan took Li Er and them upstairs, and the group quietly came to the outside of Li Tai's classroom, and did not disturb Li Tai's teaching inside, which is also what Li Er meant, Li Er wanted to see Li Tai's truest performance.

"Now you turn to page forty-five." Li Tai, who was standing on the podium, said with a serious face, although Li Tai still looked childish, and the students sitting below were all adults with an average age of twenty-five years old, but Li Tai was not stage frightened at all when he stood on the podium, but talked about it all in one place.

"We can see that we have a total of thirteen types of climates, the first one, the rainforest climate, which I haven't been to either, so I can't come up with a completely accurate description, but that doesn't stop us from learning about it. It is characterized by high temperature and rain throughout the year, according to the records in the book, the climate of this place, basically every month is like summer, and it is very rainy, and the rainy season is evenly distributed, and there is no obvious dry season. After Li Tai finished speaking, he turned around and picked up a piece of chalk and began to draw on the blackboard.

Although the drawing is very simple, the students below all look like they are listening carefully.

"What is this drawing, isn't it just a few lines?" Li Er, who was standing outside the door, asked a little strangely. When Empress Changsun heard Li Er speak, she hurriedly made a silent gesture to Li Er, and she could see that although Empress Changsun couldn't understand what Li Tai was saying, she just loved to listen.

And Li Lizhen also listened attentively to what Li Tai said inside, Li Liqin is now very curious about everything in the academy.

"The origin of tropical rainforests is very simple, because the area is controlled by the equatorial low pressure throughout the year, and updrafts prevail. That's the point, you remember, if I have the chance, I'll definitely go to see where it is, whether it's like the book. Li Tai said with a look of fascination.

"Teacher, will we have a chance to see this wonder?" The student sitting below asked.

Before Li Tai could answer, Li Er clapped his hands and walked in from outside, Zhang Nan looked at Li Er's three-fat appearance, and couldn't help but feel a burst of amusement.

"That's right, since Qingque is determined to go all over the world, I must fully support you." Li Er said with a smile.

As soon as Li Tai saw Li Er walk in, he immediately saluted Li Er and said, "I've seen my father." When the students present saw Li Tai saluting, and they were talking about their father, they all quickly stood up and saluted Li Er: "The grass people see the emperor." ”

Li Er smiled and waved his hand and said, "Okay, let's be polite, you are all students studying geography, right? Who said that, stand up and let me see. ”

Hearing Li Er say this, everyone's eyes were focused on a young man.

"Oh? It seems to be you, did you say that? Li Erdao.

The young man was very nervous in the face of Li Er's question, and stammered: "Yes, it was the grass people who said it, the grass people, the grass people lost their words for a while, and they hope that the emperor will forgive their sins." ”

"Eh, I didn't say that you said it badly, what you said was simply too good, do learning, since it is geography, then naturally you have to take a walk and see. Your ambition to go all over the world is not bad to me. In this way, in the future, when our Datang land has this or something tropical or something you just talked about, then you can go casually. Li Er said with a smile.

When the young man heard Li Er say this, a look of surprise suddenly appeared on his face.

"Okay, you are all the pillars of the academy, and the future of the academy depends on you, I hope you can enrich your knowledge and produce more useful talents for my Datang professor." Li Er also said his words again at this time.

"The grass people will live up to the emperor's trust." Everyone said in unison.
