The security guards looked stupid, Li Aiguo was the vice principal of the school, and he didn't need to mention the strictness to them on weekdays, he never thought that he would be so respectful to the young man in front of him.

Sun Hancheng glanced at the security guard and asked, "May I ask if this person I am looking for is qualified?"

The security guard showed a wry smile and said, "Qualified, qualified." ”

"Then can I go in without a teacher's ID?" asked Sun Han.

"Yes, of course. The security guard's face flushed, as if he had been slapped in the face several times.

Sun Hancheng glanced at Li Aiguo and said, "Thank you Principal Li, I still have class and I'll leave first." ”

Li Aiguo saw the scene just now in his eyes and said: "Teacher Sun, please, today's matter is really very bad, I will definitely fire this security guard who is not long-sighted." ”

Sun Hancheng, who was about to leave, immediately stopped when he heard this, turned his head to Li Aiguo and said, "Principal Li, although this security guard is wrong to scold, he also acts in accordance with the rules, and if he is wrong, he will not be expelled." ”

After listening to this, Li Aiguo laughed and said, "Okay, I must criticize this kid well afterwards." ”

Sun Hancheng didn't have time to say anything and walked towards the school, and after walking a short distance, he heard very rapid footsteps behind him, and it turned out that Li Aiguo was chasing after him from behind.

Li Aiguo ran to Sun Hancheng's side and said to him, "Mr. Sun, there is one more thing to discuss with you. ”

Sun Hancheng looked at Li Aiguo and asked, "Principal Li, please have something to say." ”

The two walked side by side, and Li Aiguo said as they walked: "Actually, there is nothing big about it, it is about your class, and it is also the reason why our school is so strict with today's inspection." ”

Sun Hancheng glanced at Li Aiguo with some surprise and asked, "Could it be that the inspection is so strict and has anything to do with my class?"

Li Aiguo laughed and said: "Yes, it is because we know that there is Teacher Sun's class today, and since the day before yesterday, there have been many people on the Internet who have resold the location of the electronic interactive classroom when you were in class, and it is also to curb this behavior, so we decided to close the school gate and only allow the students of this school to enter and exit." ”

Only then did Sun Hancheng know the reason why the school was so strict this time, and he asked a little funny: "How much is the seat for me in class?" ”

Li Aiguo was a little surprised that Sun Hancheng asked such a question, and just wanted to speak, he heard Sun Hancheng say with a smile: "Teasing you, such a thing should be stopped, this is the school's decision, don't tell me, I'm just here to give a lecture." ”

Sun Hancheng looked at the time on his watch, and then quickened his pace, Li Aiguo, who had been following Sun Hancheng's pace, had no choice but to speed up his pace and follow, and said as he walked: "That's the case, we discussed it and decided to put Teacher Sun's class in the auditorium of our Nanjiang Normal University from the next class." ”

"Auditorium?" Sun Hancheng really didn't know where the auditorium of Nanjiang Normal University was.

Perhaps it was because he saw Sun Hancheng's question, Li Aiguo came to you and explained: "The auditorium is at the top of our building, and it is the largest room in our school, and it is generally only open when major festivals are celebrated. ”

"Yes, as long as the school thinks it's okay. ”

After Sun Hancheng finished speaking, he quickened his pace again and walked towards the electronic interactive classroom.

Before he reached the electronic interactive classroom, Sun Hancheng heard a noisy sound in the distance, and saw several security guards in the school driving away the students who couldn't get in outside the classroom.

After seeing Sun Hancheng coming, many people ran in the direction of Sun Hancheng, and they still shouted Sun Hancheng's name in their mouths.

Those security guards also immediately ran over to maintain order, making Sun Hancheng feel like a star.

"Mr. Sun, we didn't grab the position. ”

"I came to the queue last night, and I originally occupied the position, but I didn't expect that I couldn't get in after I came back from a toilet with a stomachache. ”

"Mr. Sun, I am from Nanjiang University, and I finally skipped class to listen to your lecture, but I didn't expect to come too late. ”

Sun Hancheng saw that there were a lot of people who didn't grab the position, thinking that what Li Aiguo said was indeed a better choice to change to a larger classroom, anyway, it was the same for him whether there were a hundred or a thousand people in the audience.

There are many advantages to changing to a larger classroom, at least not to make a student queue up in order to listen to his class in the evening.

Sun Hancheng successfully entered the classroom under the escort of a group of security guards, and when he saw Sun Hancheng arrive, the audience burst into warm applause, as if he was cheering for Sun Hancheng's return.

Among these people, Sun Hancheng still saw a few familiar figures, all of them were students who came to listen to his lectures a few times before, and some screams could be heard in addition to the applause.

A few girls may have been too excited to see Sun Hancheng, so they couldn't help but scream excitedly, attracting surprised glances from the people around them.

Sun Hancheng waved his hand to make everyone quiet, and after seeing Sun Hancheng's gesture, everyone quieted down, or sat on the seat or sat on the steps, quietly waiting for Sun Hancheng to give a lecture.

Sun Hancheng took a bag and put it on the table casually.

In fact, Sun Hancheng had also prepared for class before, and it can't be said that he was deliberately preparing for class, because a lot of knowledge was memorized in Sun Hancheng's mind, and he just found out this knowledge and synthesized it into a topic.

There are so many things in his mind that he can take out and talk about, but after there are too many things, there are also a lot of worries, such as what to talk about this time.

Originally, Sun Hancheng wanted to talk about Chinese painting, but because he had been thinking about the bronze sword in his mind for the past few days, a new topic was derived.

The big screen in the electronic interactive classroom was not turned on, and Sun Hancheng didn't know how to use it, so he casually found two students to come up and help.

Sun Hancheng took out a USB drive in his bag and inserted it into the computer, which contained some materials he had prepared in advance.

Soon, the content of this lecture was displayed on the big screen: "The Characteristics of this Dynasty from the Representative Artifacts of Various Chinese Dynasties".

The reason why Sun Hancheng was able to think of this topic was because of the bronze sword, because the bronze sword was a very representative thing from the Shang and Zhou dynasties to the Spring and Autumn Period and the Warring States period.

In the exclamation of the students, the words Shang Zhou appeared concisely on the big screen, and they all understood that Sun Hancheng was going to start with Shang Zhou.

Sun Hancheng first introduced the Shang and Zhou dynasties, and then immediately appeared the representative artifacts of the Shang and Zhou dynasties, and some photos of the bronzes appeared on them.

Whether it is a bronze ritual vessel such as a bronze tripod, or a bronze weapon such as a bronze sword and a bronze Yue, Sun Hancheng has a very detailed introduction.

The students in the audience all found these things, and the photos taken by Sun Hancheng were very clear, they were the kind of close-up photos that are generally difficult to see, and some were taken with mobile phones, but they were still very clear.

Just like the last time I talked about the 20,000 years of Chinese porcelain, all the pictures on this were taken by Sun Hancheng himself, some were close-up photos of Sun Hancheng when he visited the museum, and some were identified by Sun Hancheng's hands.

When talking about the bronze artifact, Sun Hancheng focused on the bronze sword, because he has been thinking about the bronze sword for the past few days, so all these related knowledge can't help but emerge from Sun Hancheng's mind.

He told the students many stories about bronzes that he had personally identified or encountered, and everyone who listened to them was hooked.

After the bronzes are described, there are the terracotta figurines of the Qin Dynasty, the murals of the Han Dynasty, the calligraphy of the Wei and Jin dynasties, and the grotto art of the Northern and Southern Dynasties.

Sun Hancheng far underestimated his ability to lecture, because from time to time new ideas popped up in his mind, he couldn't help but say them, resulting in a lot of time.

This class lasted for two hours, and at eleven o'clock, Sun Hancheng reluctantly talked about the art of grottoes.

Speaking of grotto art, Sun Hancheng's words could not be held back again, Sun Hancheng grew up in a small mountain village in the northwest when he was a child, not far from there is a grotto that flourished in the Sui and Tang dynasties in the Northern and Southern Dynasties, which is still a place that has not been developed on a large scale, but let Sun Hancheng understand the charm of grotto art better than anyone else.

It is precisely because Sun Hancheng is talking about the real grotto art that everyone doesn't know, so many people listen to it interestingly, although the Internet is very developed now, but not everything can be searched, at least these things that Sun Hancheng told are things they don't know.

Sun Hancheng saw that a few of his classmates might want to go to the toilet, but he didn't want to blame Sun Hancheng's class for being very uncomfortable.

He looked at the time, sighed and said helplessly: "I originally wanted to give you a casual chat, but I didn't expect it to be over as soon as the chat started, I only talked about the Northern and Southern Dynasties today, and the time has been two hours, let's talk about it here today." ”

"No, we're going to keep listening. ”

"We haven't heard enough yet, so let's talk about another dynasty. ”

"Yes, Mr. Sun can talk about another dynasty. ”

Sun Hancheng heard the voices of the students in the audience and said with a smile: "Don't worry, everyone, I don't just teach this class, I will have one to two classes every week in the future, as long as everyone thinks that my lectures can still be listened to, they can come." ”

Everyone in the audience couldn't help but feel a little disappointed, and someone shouted: "Who knows if you can grab a place in the next class." ”

This sentence resonated with many people, and they all said that it was not easy to grab a seat.

Sun Hancheng waved to everyone again and said: "I know that it is not easy for everyone to grab seats, the school has decided, from the next class onwards, my position will be changed to the auditorium of our Nanjiang Normal University." ”
