"The content we mainly learn this semester is from ancient times to the Wei, Jin, Southern and Northern Dynasties, and the next semester will continue to learn before the Opium War, and I will teach you in these two semesters."

The second big class is a professional class in the history department, an old man walked in slowly, said his name and then began to get into the topic, which was very different from the previous English teacher, and he didn't mean to introduce himself at all.

"I didn't expect it to be an old man, I don't even have a name, it seems that I am comfortable now" Zhuang Yahao whispered on the side, his favorite is this kind of teacher, he is not strict, and he skips class if he wants to.

Li Zimu shook his head and didn't speak, how strong a school is, the main thing is to see how many old men there are in this school, don't look at the age of these lecturers, but Li Zimu has no doubt about his level, this kind of precious resource is not cherished by anyone.

"This year's book uses the textbooks of Beijing Normal University, and the publication time is relatively far away, so the latest research report is not written here, I will make some additions to you, and there are a few mistakes in the book, and I will put them forward for you to correct when the time comes" The old man nodded and said, not caring about the enthusiasm of the students in the audience.

Li Zimu nodded, he turned over the book in his hand a few days ago, there are indeed a few mistakes, although he has not experienced it in ancient times, but he has read a lot of books about that period, most of the ancient books have been lost a lot after the change of dynasties, in that era when printing technology has not yet come out, every book is precious.

Taking the most typical Confucian classics as an example, today's Confucian classic books are not the same as those compiled and handed down by Old Man Kong at the beginning, and some of them are still very different.

The reason is that when Yingzheng burned books and pit Confucianism, most of the authentic Confucian classics were burned to ashes, and at that time, there were still seven or eight hundred years before the printing technology of the Tang Dynasty came out.

Poetry and books are easy, rites are in the Spring and Autumn Period, and the number of the Six Classics should be stressed. "Poems", "Books", "Rites", "Yi", "Music" and "Spring and Autumn", later generations called them "Six Classics". And these six classics have existed long before the birth of Old Man Kong, but they are just unified by him, and their nature is similar to today's Siku Quanshu, mainly collected and summarized, and only a few things are written by themselves.

After the Ying Zheng incident, there are only a few authentic Confucian classics in the world, all of which are hidden at home by some people who are not afraid of death.

Even the long-lost "Book of Music" he had the pleasure of reading, but he didn't think about preserving it at the time, and now he really regrets it.

By the time of the Han Dynasty, Confucianism was the only official doctrine that provided the rulers of the past dynasties with an official doctrine of centralized monarchy, but at that time, the Confucian classics had been almost burned, and Dong Zhongshu, as the inheritor of Confucianism, how should he restore the Confucian classics?

Fortunately, there were still a few disciples of the old man Confucius at that time, and some of them were not dead, so Dong Zhongshu sent someone to find them to endorse and write them down, but these people were all seventy, eighty or ninety years old, and almost all the things they learned from Confucius were returned to their teachers......

So many of the things they recited were wrong, but this did not affect Emperor Wu of the Han Dynasty to pass them on, because many of them were added by him to Dong Zhongshu himself, which was conducive to consolidating his rule anyway.

As for what he said later, he found a lot of genuine works from the walls of Old Man Kong's house, these are all lies that the ruler of the dynasty wanted to add things to himself, and made up lies to confuse the people, who would be so bored that he hid the book in the wall?

It wasn't until the advent of printing in the Sui and Tang dynasties that books began to become less valuable, and the number of people who read books began to gradually increase, so in Li Zimu's eyes, it was not until the beginning of the Sui and Tang dynasties that the readers really straightened their waists.

He thought to himself, those brutes were all good at the things of their ancestors, and he was the most unreadable as a scholar, so he took and flipped through all the books that came out of various dynasties and generations that he could read.

Li Zimu listened quietly to the lecturer on the podium, a small number of people in the audience were no longer interested in this kind of boring content, sleeping and playing with mobile phones, the old man didn't care when he saw it, he was still talking about himself.

This kind of old lecturer generally does not use PPT, and some don't even bring the book to turn it over, but they still talk about the head of the Tao, and what they want to write down is written on the blackboard with chalk, this ancient way of teaching is naturally not liked by most young people today.

"Ah...... Finally got out of class, starved to death" As soon as the bell rang, Zhuang Yahao raised his head on time, yawned and said, the lecturer on the stage is also a little away after class, not dragging mud and water, in college, there has never been such a thing as procrastination.

Li Zimu closed his book and stood up and walked outside, when school started, tourists were not allowed to come in to play, this is the rule that came out last year, and it can be regarded as a good thing that Zhu Congshi did, otherwise these students would not think that they would be able to eat.

Li Zimu and a few of them went to the cafeteria to buy food, and after returning to the dormitory to eat, they began to prepare to take a nap, and there was still a class in the afternoon, so Li Zimu was not ready to go back.

"Eh, do you want to play a basketball game?" Zhuang Yahao shouted loudly as he pushed open the door. Playing basketball is a good opportunity for a good girl, and he will never miss this kind of thing, although he is not very good at playing basketball......

"Go, why don't you go?" Li Tian said with a smile, his only leisure sport in the army was playing basketball, so he still has some skills for this sport......

"What about Jingyang?" Zhuang Yahao turned his head to look at Zhang Jingyang and said, there are few male students in the history department, and the more the better, in line with the principle of casting a wide net.

"No," said the latter, eating without raising his head.

"Then ......" Zhuang Yahao was about to turn his head and ask Li Zimu, but when he saw Li Zimu glancing at him, he swallowed his words stiffly.

Li Zimu didn't want to do anything that would show his head, whether he was interested in this or not, except for some necessary occasions when he had to show up, he would rather stay at home and not move.

"By the way, Jingyang, I want to discuss something with you," Li Zimu thought of something, raised his head and said to Zhang Jingyang.
