Behind the huge wall is a pond that separates the history museum from the bookstore.

The door of the history museum is about two zhang wide, two carriages can be parallel, in addition to the center of the lintel hangs a plaque of the history museum with a length of one zhang and a width of three feet, the three-foot thick doorposts on both sides are still engraved with a couplet.

Left Union: Remembering the Three Emperors and Five Emperors, it is orthodox in China.

Right link: Thousands of years, written in history.

Passing through this gate, in addition to a courtyard behind is a layer of rooms, which used to be the living rooms of the servants and servants of the Changyu Courtyard, but after the repair, the redundant ancillary facilities were removed, and all of them were transformed into office rooms, and all the rooms were modeled after the layout of the Academy of Sciences and the Newspaper Museum, and the rooms were divided into small rooms with wooden boards for the clerks and school officials, and the same was true for the backyard, but the editor-in-chief and other leadership positions were each in a separate room.

At this time, dozens of rows of seats have been placed in the courtyard, and there is a separate set of seats in the front, which is prepared for Chen Xu, and a large blackboard is also set up behind this set of seats, which reads Welcome to the History Museum of Qinghe to teach.

Looking at the words on this big blackboard, Chen Xu's face twitched slightly, and then he strode to his exclusive position and sat down, and then An Yuliang and Chen Ping, who followed, and a group of leaders of the Academy of Literature and the editor-in-chief of the History Museum all sat in their positions, and the others could only stand and listen to the lecture.

The reason for teaching the history museum is that the historical materials that have been handed down today are too complicated and disorderly, and if there is no unified format to constrain them, I am afraid that after sorting them out, they will still be messy, resulting in confusion among the people who read them, and it is very necessary to determine the method of sorting out the historical materials first.

And this method must be chronicles.

The origin of the chronicle history book is very early, starting from the Spring and Autumn Period, the Confucian historians of the Lu State were the first to adopt it, and compiled the book "Spring and Autumn", which records the events that happened from the time when King Zhou Ping moved the capital to the time before the three Jin and the Seven Kingdoms became dominant, and the time was sorted out with the year name of the Lu State, so there is a complete timeline, so that the history recorded in the Spring and Autumn Period has a very clear timetable, and it does not seem to cause confusion, and this chronicle has been greatly respected by later historians, Sima Guang in the compilation of "Zizhi Tongjian" This is the type of chronology that was used.

Because the book "Spring and Autumn" was compiled by Confucian historians, it was later sorted out by Confucian disciples to form the Confucian scriptures, and it was listed among the must-read books of the Four Books and Five Classics for Confucian disciples.

The advantage of the chronicle is that the time context is clear, and the events that occurred can be recorded in detail with time as the axis, but the entire 800 vassal states of the Great Zhou Dynasty, I am afraid it will be very complicated to connect them only with a timeline, and there are too many things happening among colleagues, and the history of the vassal states and celebrity biographies cannot be clearly expressed, so Chen Xu is also ready to introduce the "Historical Records" genre of Sima Qian, another historian, as a supplement.

Historical records use different structures such as chronology, chronicles, families, and biographies to record history, so that when combined, a complete and detailed historical record can be formed.

After everyone found a place to sit and stand, the scene began to slowly quiet, and Chen Xu instructed his entourage: "Bring my manuscript!" ”

"Yes, Master Hou!" An entourage hurriedly took off a cowhide satchel on his body and put it on the table in front of Chen Xu.

Chen Xu slowly opened the buckle and took out a stack of written hemp pulp paper from his shoulder bag, and there was no sound below at this time.

"Wipe the blackboard clean!" Chen Xu commanded again, and a scribe in charge of teaching arrangements quickly erased the welcome message on the blackboard.

"The significance of preparing the history museum is very significant, just like the couplet at the door said, this is a necessary and important means for our descendants to commemorate our ancestors and inherit Chinese civilization, from ancient mythology to the three emperors and five emperors and then to the present Great Qin, during which there have been countless heroic stories that make people sing and cry, and there have been countless ups and downs, but many of them have been slowly lost in the long river of time with the passage of time and cannot be found, this is not only history, but also our inheritance ......"

Chen Xu said as he picked up the chalk and wrote a paragraph on the blackboard.

"With copper as a mirror, you can be dressed; With the ancient as a mirror, we can know the rise and fall; With people as a mirror, you can see the gains and losses. ”

Looking at Chen Xu's words written on the blackboard, everyone including An Yuliang was moved.

The thousands of people here are all real scholars of the time, and naturally they all quickly appreciate the meaning, and many of them can't help but read it out with their beards.

"The purpose of compiling historical books is not only to simply record and inherit, but also to use these historical records to spur ourselves to warn future generations, why Xia Wei will die in the country, why Shang will mess up the dynasty, why the Great Zhou will decline...... Can't inherit history, that is, in denying the merits of our ancestors, can't face up to history, can't let us go further, so you compile history books, you must be impartial, no joy or sorrow, fair and selfless history will be completely restored and recorded, in your mind, there should be no home and position, you are standing in the perspective of saints, regardless of right and wrong, good and evil to look down on history, look down on those heroes, look down on those princes and kings, with the pen in your hands, will be a complete record of what happened, In this way, all those who see these historical books can really use it as a mirror, understand their own gains and losses, and appreciate the rise ......and fall and success and failure, and these historical books will also be passed down for thousands of years, and future generations will also use their historical pens to record the successes and failures of our contemporaries.

"The compilation of historical books has actually been preceded by the style, the former Lu State historian has compiled the "Spring and Autumn Period", and Zuo Qiu Ming has also made detailed annotations for this, so our history books are also based on the "Zuo's Spring and Autumn Period", "Ram Biography", "Gu Liang Biography" as the genre, with the timeline as the central axis, so as to complete the sequence of ancient mythology, three emperors and five emperors, Xia, Shang, Zhou and other dynasties, so as not to appear confusing......"

Chen Xu said as he drew a chronological table on the blackboard to write down these historical dynasties.

"Of course, time alone is not enough, because there are also events caused by the division of princes and the struggle for hegemony converge and merge, and the time of many events is concentrated together, and the records of the same thing are not the same because of the different positions of each country, so we need to sort out this matter and list the princes, countries and characters clearly, so Benhou introduced several other genres, that is, the Benji, the family, the biography and the table ......"

"This era, that is, the kings of the orthodox dynasty, the three emperors, the five emperors, and the kings of the Xia and Shang dynasties are among the kings of the Benji."

"The family, that is, the princes, the princes of the Xia, Shang and Zhou dynasties, and the heirs of the inheritance are all listed among them."

"The biography is an important figure of each dynasty, the word ancestor Changjie, the wine ancestor Du Kang, the ancestor of Le Zu Linglun, Taigongwang, Guan Zhong, Yi Yin, Wu Zixu, Bian Que, Boya and many other ancient figures are listed among them."

"The table, which is the most important part, is to list the above categories according to the chronological order, and run through the whole set of historical books according to the chronology of the dynasties, so as to form a clear context, like a vine for the viewer to be clear and unmistakable......"

When Chen Xu narrated, he took the vertical table as the main trunk, and constantly spread the branches and leaves on both sides to list the princes who were divided, and then used the princes as the branches to scatter the respective development processes of the vassal states around.

The people listening below were silent.

Everyone was deeply attracted by Chen Xu's novel illustrated explanation, and at the same time, they were also incomparably excited about the classification of the Benji, the family, and the biography.

If it is compiled according to Chen Xu's method, this unprecedented set of historical books will definitely become a perfect classic for the world, and all those who participated in the compilation will also be listed in the upper class.

Therefore, while everyone was listening, countless pairs of eyes began to shine with scorching brilliance, and they couldn't wait to run up and split the little marquis's head to see what kind of demonic soul was hidden inside.

Chen Xu spent about forty minutes to finish the lecture, and then faced countless questions, including An Yuliang, who couldn't help but stand up excitedly and asked several questions that he still didn't understand or still had doubts.

On the first day of autumn, the sun was shining, the weather was unusually hot, drier and hotter than the scorching summer, Chen Xu's mouth was dry, and he drank several cups of herbal tea sweating all over his body and still did not quench his thirst.

But in the face of the enthusiasm of everyone in the History Museum, I had to calm down and explain carefully.

This is because if we don't explain it clearly now, it will be even more troublesome if we start compiling it.

It was a full two hours before the lecture on the History Museum was over, and it was already noon.

In the cafeteria of the Faculty of Arts, An Yuliang, Chen Ping, and a group of doctors and doctors ate a simple meal to satisfy their hunger, and after resting for half an hour, Chen Xu came to the bookstore next door again.

The internal layout of the bookstore is similar to that of the History Museum, but the area is much larger, more than three times the size of the History Museum, with more personnel, more houses and more.

There is also a bookshop plaque at the entrance, and a couplet is engraved on the doorposts on both sides.

Left Alliance: A hundred schools of thought contend, benevolence, morality, propriety and righteousness are the right way.

Right link: Ten thousand years of inheritance, poems, books, scriptures and meanings are all articles.

At present, there is no such thing as couplets in Daqin, and there are no couplets hanging in various temples and buildings, but in later generations, various Taoist temples or pavilions and other monuments have couplets, which not only make people feel insightful, but also associate with many stories that have been circulated.

And as a faculty of letters, it always seems that it is not enough to be atmospheric and high-grade without carving a few couplets, so Chen Xu racked his brains at home to write these two couplets of the History Museum and the bookstore.

This picture at the door of the bookstore is not atmospheric enough, on the contrary, the pattern seems to be very small, and it seems that Confucianism is very respected, but it is not the case, in fact, all the sons of the hundred schools of thought except for the Legalists are basically emphasizing benevolence, morality, etiquette and righteousness, so Chen Xu's benevolence, virtue and etiquette just hit the hearts of everyone in the Academy of Literature, so after Chen Xu put forward this couplet, a group of people in the newspaper hall and An Yuliang all gave a very high evaluation, thinking that these two sentences are very appropriate to be engraved at the door of the bookstore.

Not only that, but all the students who came to report to the Faculty of Arts also praised it, believing that this couplet perfectly illustrates the purpose and purpose of the bookstore.
