The library building in Cai Yong's Mansion is a separate two-story brick and wood structure building, strictly speaking, it should be two and a half floors, because in order to prevent the books from being too close to the ground and causing dampness and mildew, it is deliberately raised about one meter, and then sprinkled with lime under the floor slab to prevent insects and ants, which shows the degree of care for the books. Pen, fun, and www.biquge.info

There is a small gallery in front of the library building, and there is a small pavilion on one side of the gallery.

Cai Yong stopped and said to Fei Qian: "It's inconvenient for me to go upstairs with my legs and feet, and let Senior Sister Ru replace ......" and then told Cai Yan again, let Cai Yan take Fei Qian to the library to have a look, and walked to the small pavilion and sat down.

Cai Yan's eyes turned slightly, a little smile appeared on the corner of his mouth, and he said, "Senior brother, is it the first time to go to my family's library?" Cai Yan's tone and words are very casual, and there is no feeling of strict prohibition and restraint at all, but it is like a relaxed atmosphere between friends.

"Yes," Fei Qian looked up at the tall library building, and the admiration in his heart spontaneously arose, "Such a large library building is really the dream of all the readers in the world......

Cai Yan held the book slip and led the way in front of him, and said slowly: "It was stored in the room before, but then there were more and more books of all kinds, and in the end it was impossible to put it down, and because of the inconvenience of ventilation, it was easy to attract insects and ants, so I couldn't take care of it, so I simply built this building." ”

Cai Yan gently pushed open the hidden door, like opening a book, and then stood on the side of the door and made a gesture of please......

"Senior sister, please first!"

Cai Yan pursed his lips and smiled, no longer polite, and walked into the library building generously.

Fei Qian followed behind Cai Yan and also entered the library building, raised his eyes, and couldn't help but gasp......

This scale, it's amazing!

You must know that now it is the Han Dynasty, and all the books are made one by one, one stroke at a time, which is completely different from the situation in later generations when the printing machine is turned on, and thousands of copies come out.

In the Han Dynasty, a book was worth a thousand gold, and Cai Yong's library had so many books and books, if it was calculated according to the market price, this was simply a peerless rich......

However, Fei Qian only dared to think about it in his mind, if he dared to say it, not to mention that the book in Cai Yan's arms would bloom on his head, maybe Cai Yong would directly remove him from the door wall......

In the Han Dynasty, there was an unusual respect for knowledge.

Cai Yan was unusually familiar with the bookshelves in the library building, and while walking forward, he introduced: "Most of this floor is two strategies for mathematics and poetry, and the six arts and Zhuzi are all placed upstairs, as for the square skills and military books......

Cai Yan said, turned lightly in the middle of the bookshelf, walked to a bookshelf, put the book in his arms on the shelf, and then said: "...... Fang Technique and War Book basically belong to each family's treasures, and it is difficult to collect, so it is ......"

Fei Qian roughly counted, in this floor, there are about fifty or sixty bookshelves used to put books, each bookshelf has four layers, each layer is more or less a variety of books and books, all kinds of weft knits of different lengths are dotted on the books that are mostly blue and dark, like a colorful and beautiful abstract oil painting......

The Cai family's method of classifying books is carried out in accordance with the official classification method. Because from the Spring and Autumn Period and the Warring States Period, until the Qin Dynasty, there was no condition for large-scale sorting and classification of books, until the Han Dynasty, after the whole society gradually settled down, Liu Xiang, Liu Xin and his son presided over successively, and the books sorted out at that time were divided into six categories: Six Arts, Zhuzi, Military Books, Mathematics, Fang Techniques, and Poetry.

The book of soldiers has always been the secret transmission of various families, and it is never easy to show people, and Fang Ji is the foundation of the doctor's foothold, and it is not easy to pass it on, and Cai Yong's own research focus is on the classics and history, so it is reasonable that Fang Ji and the Book of War have not been collected......

But even so, such a huge number of books is quite amazing, Fei Qian slightly estimated, this floor alone is about 5,000 books and books, so two floors, the collection of books is tens of thousands......

This was not the case with some of the smaller libraries of later generations.

Fei Qian was amazed, took a volume of books from the bookshelf on his side, opened it, and saw that it was written "...... The western capital of the Han Dynasty lies in Yongzhou, which is actually called Chang'an. Left according to the Hangu, Erkun block, the table Taihua, the mountain of the south of the ......"

This turned out to be such a coincidence, now that he is going to move the capital to Chang'an, he took a scroll casually, and it turned out to be Ban Gu's two capitals, so that Fei Qian really didn't know whether it was better to cry or laugh......

Seeing Fei Qian close the book and put it back on the shelf, Cai Yan smiled, then turned around and led the way.

After turning to a bookshelf, Cai Yan stopped and Wen Yan reminded: "The stairs are steep, junior brother should be careful." ”

It turns out that in order to free up more space to put bookshelves in the library building, the stairs built are not as delicate as the general floors, it is a simple wooden ladder that goes up and down, and it is narrow and steep, not very easy to walk, like Cai Yong is older, his legs and feet are not very convenient, and it is not easy to go up and down.

When Fei sneaked up to the second floor, he saw that there were no books piled up on the shelves upstairs like on the first floor, and some bookshelves and even the entire shelves were empty......

Cai Yan walked to an empty bookshelf, gently stroked it with his hand, the expression on his face was a little lonely, and said slowly: "...... Originally, these bookshelves were also full...... Nowadays...... Wandered away......"

The sunlight shone in through the lintel on the second floor, passed through several empty bookshelves, and fell mottled on Cai Yan, which seemed to be appeasing Cai Yan's sadness......

Time seemed to freeze at this moment, and Fei Qian suddenly felt a little dazed, as if he had returned to the library when he was in college in the later life, and it really seemed to be like the situation at that time......

Cai Yan raised his hand and pulled the strand of green silk that fell behind his ear again, smiled lightly, and said, "After reading it for so long, has the junior brother thought about what book to borrow?" You can borrow up to three books at a time, so you should know that you can't be greedy for reading......"

"Borrowing books......" Fei Qian couldn't help but smile bitterly and said, "Senior sister, I'm ...... this time Not to borrow books, but to ...... I want to move books...... I'm going to move them all out......"

"Huh?!" Cai Yan's eyes suddenly widened, and a ridiculous thought suddenly appeared in his heart, this junior brother should not be some robber pretending......
