Watching Chen Fan walk down the embankment and disappear into the passage through the cracks of the house, Jiang Tiantian took a deep breath and prepared to go back to work in the store.

She was about to go down when she suddenly slapped her on the head, didn't I go this way too? Why weren't we together just now?

In the next second, she reacted, I am afraid that Chen Fan deliberately separated from her, just to help her avoid suspicion.

Otherwise, if she is seen walking with a man by a nearby acquaintance, I am afraid that there will be gossip flying around, although she doesn't care about it, but after all, there will be some trouble.

This man is really careful.

Jiang Tiantian pursed her lips and smiled, trotted down the embankment with something, walked back briskly, and after a while, she passed through the complicated alleyway and entered the store.

In a place where she couldn't see, Chen Fan turned out of an alley, glanced at the back of her stepping into the store, and confirmed that she was safe and sound, before turning around and walking towards the intersection.

A few minutes later, when I walked to the door of Xinhua Bookstore, I saw Zhang Wenliang, Zhang Juemin and the rider squatting on the side of the road smoking cigarettes, turning their heads to look this way from time to time.

Zhang Wenliang was the first to see him, and immediately stood up on the ground, but his legs were numb, and he couldn't help but stomp his feet, and when he got a little closer, he sighed and said, "Nearly an hour, where did you go to deliver the letter?" ”

Zhang Juemin thumped his legs, "It can't be crossing the river, right?!" ”

Chen Fan also sighed faintly, "I was in a hurry, so I specially asked someone to take a shortcut, and then I got lost, and it took a long time to come out." ”

The three of them looked at him speechlessly, such a big person, he would even get lost?!

Chen Fan glared, "Don't believe it." ”

He turned and pointed behind him, "Just that house, you guys will walk through it for me?" ”

The rider suddenly said, "What is the shortcut you copied from the residential area?" There are hundreds or thousands of households in that place, and the alleys inside are like a maze, and outsiders generally dare not enter for fear of not finding the direction.

And at this point in time, everyone is at work, only some elderly people are at home, and it is not easy to find even a person who asks for directions, so it is good luck that you can turn out. ”

Hearing this, Chen Fan immediately said confidently, "Listen, it's not me talking nonsense." ”

Zhang Wenliang saw that the riders said so, and he could only give two thumbs up, "I obeyed." ”

Then he pointed to the bookstore, "Aren't you going to buy books?" Hurry up and buy it. ”

Chen Fan looked at them, "You don't go in?" ”

Zhang Juemin waved his hand again and again, "Don't look at it, don't look at it." I don't know a few words, and I have a headache when I go in and see a book. ”

Zhang Wenliang and the rider master also looked like they had palpitations, and they obviously had a headache.

Chen Fan laughed, gestured and walked inside, "I'll try to be as fast as possible." ”

This bookstore is not big, only 200 square meters, and the counter at the entrance is a special counter for propaganda posters, hanging portraits one after another, 80 percent of which belong to Mr. Li, the remaining half to Mr. Hua, and finally half to Lenin and Marx.

Basically, it's just the four of them, no one else, at least Chen Fan didn't see it.

A whole wall facing the gate is a stationery and sporting goods counter, there are a few air guns hanging on the wall, but there are no shotguns and pistols, there are basketballs, footballs, volleyballs, table tennis rackets and badminton rackets, skipping rope, Go, chess and other common cultural and sports goods on the counter.

Then the innermost counter opposite the poster counter is the cash register, where the salespeople are wearing green military uniforms, blue pants, and a liberation cap.

In the middle, there is a large open space with a personal height of A-shaped bookshelves, and there are a few customers shopping for books in it.

Chen Fan walked around it and felt that there were not many varieties of books here, probably because it was just a branch of the street, and it was close to the cotton mill, so except for a few regular philosophical and literary books, most of the others were mainly textile professional books.

If it was before he met Jiang Tiantian, he might buy a few of these textile reference books and take them back to read, but now of course there is no need to worry, wait until he goes to the scrap recycling station to pick up the old books, if there is no one there, he will come here to buy them again, or it is not too late to go to the central bookstore to buy them.

Just when he was about to pick two books and leave, his eyes suddenly lit up, and at the bottom of the teaching and auxiliary bookcase, he took out more than a dozen books, and then stopped picking more and went directly to the cash register to settle the bill.

The salesman was taken aback when he saw him bring so many books, and when he saw the title of the book clearly, he couldn't help but look at him with curiosity, "Little comrade, which school did you graduate from, are you so studious?" ”

Chen Fan smiled shyly, "It's just that I'm interested in learning and want to learn at home." ”

The salesperson nodded while making calculations and said, "There are not many people who love learning these days, after all, school and work rely on recommendations, and many people don't like to study."

However, they didn't think that they had to learn when they worked, otherwise how could they do their jobs well, if their academic performance was not good, they would be prone to problems in their work in the future, and they could be promoted quickly if they studied well, did you say this is the truth?

That's why our leaders insist on putting this set of books here, but there are only a few people who come to buy this kind of book a year, but I didn't expect one to come today, or buy a full set. ”

She tore off the bill and handed it to the cashier next to her, raised her head and smiled, "You love learning so much, you will definitely be able to make a profit in the future." ”

Chen Fan grinned and said, "I would like to ask you for good words." ”

The cashier next to him tore off the receipt and handed it to him, "Little comrade, this is a receipt, please take it." ”

With such a good attitude, it is absolutely impossible to say that there is no bonus for appearance.

Chen Fan took the receipt and looked at it, and immediately paid the bill.

When the salesperson next to him saw that he had taken out the money, he pulled out a hemp rope from under the counter, quickly divided the book into two bundles and packed them, and then cut them with scissors and pushed them in front of Chen Fan.

The set on the table is the famous divine book in the chronology, the "Mathematics, Physics and Chemistry Self-study Series", a complete set of 17 volumes, and it is the old edition in 1964.

That's right, the new edition will not be urgently printed by the Shanghai People's Publishing House until after the notice resumes the college entrance examination, and now of course only the old version can be used.

The cheapest of these books is only 2 cents 6 a book, and the most expensive is only 7 cents 4, which is naturally not discounted this year, and the 17 complete sets add up, but it is less than 10 yuan.

(This one is the 77th edition, and the 64th edition is the yellow cover)

Some people say that it is easy to make a fortune in this era of collecting, but it is a pity that it is a "post-wealth", if you don't understand the door of the collection world, if you want to realize those collections, at least after the 90s.

But there is one thing that can be realized quickly.

Hmph, as long as you are bold, you don't have to hoard stamps, hoard antiques, just hoard 10 sets of "Mathematics, Physics and Chemistry Self-study Series", the purchase price is less than 100 yuan, and so the college entrance examination notice is released, you can sell 3, 400 sets, the average price of a single book is more than 20 yuan, and there is even a limit record of 100 yuan for a single book.

As long as you dare to make a price, someone will dare to go bankrupt, smash the pot and sell iron, and the whole family is in debt to buy!

Earn him three or four thousand at a time, and he can go to the capital to exchange for 10 courtyard houses.

If it is a large miscellaneous courtyard, it is a complete set of courtyards.

If you are a little bolder, you can hoard 100 sets of him and earn him 30,000 or 40,000 yuan, which is a set of four-entry mansions with cross-courtyards and back gardens.

The rest of the money can be used for a full set of mahogany furniture, plus a full set of electrical appliances, plus a black eagle, and ......

Some people asked, why did this set of books sell at such a high price? Can't you just follow the textbook?

The reason is very simple, because the college entrance examination tests the real "theoretical knowledge", and the middle school textbooks at this time are out of touch with "theoretical knowledge"!

Previously, Chen Fan bought a full set of textbooks from primary school to high school at Xinhua Bookstore in Nanhu Commune, thinking that with this set of textbooks, he could be admitted to university.

After reading those middle school textbooks, he realized that he was thinking too much.

At this time, there were only two very thin textbooks of mathematics, physics and chemistry in middle schools, one was "Basic Knowledge of Industry", referred to as "Industrial Foundation", and the other was "Basic Knowledge of Agriculture", referred to as "Agricultural Foundation".

In the whole four-year middle school stage, in addition to Chinese, mathematics and politics, I learned these two sets of textbooks.

The content of "Basic Knowledge of Industry" only involves some physics, mainly about the structure and operation of machines, etc., while "Agricultural Foundation" will involve some content such as fertilizers and pesticides.

However, whether it is "industrial base" or "agricultural base", the purpose is to prepare for being a worker and a farmer in the future, because what is advocated at this time is that education should be combined with production and labor, and it is necessary to "apply what you have learned", so you should study "industrial base" and "agricultural base".

But with this knowledge, can you take the mathematical, physical and chemical theory test of the college entrance examination?

Obviously not.

These two sets are not so much science and engineering textbooks, but rather "professional courses" textbooks in later generations, which are still very elementary.

And before the "10 years", it was also through the college entrance examination to select talents, and the people of that year were still alive and well, how could they not know what the college entrance examination was all about?

The content on the test paper is not taught at all in the textbook!

Even textbooks are like this, and what are in other textbooks can be imagined.

What's more, there are no teaching aids now.

As a result, this set of "Mathematics, Physics and Chemistry Self-study Series", which was born 10 years ago, has become a "life-saving straw" for the majority of young people, especially the educated youth.

As long as you have the most basic elementary knowledge, you can learn by yourself through this set of books, and you can understand most of the content without the guidance of a teacher.

Isn't that enough?!

For the sake of this "life-saving straw", what is the money?!

When Chen Fan walked out of the bookstore with two bundles of books in his arms, he felt that his heart was still dripping blood.

Don't wait for me, don't wait for me!

If you can stock up on dozens of sets, making this money is not much more comfortable than working hard to pinch pottery blanks and burn pottery!

……

Hundreds of miles away, in the Lujiawan Educated Youth Academy, Jiang Lili, who was working hard to knead the pottery, sneezed inexplicably.

Huang Ying rubbed her nose, "I don't feel cold, how can I sneeze?" ”

Jiang Lili raised her head and looked at her, and couldn't help but laugh, "Yingying, the mud on your hands is on your nose." ”

Huang Ying glanced down, her two eyes were squeezed into cross-eyed, but she couldn't see the mud marks on her nose, or Jiang Lili wiped her clean with her sleeve.

Yang Ju said on the side, "When the four of them sneeze together, it must be cold weather, otherwise how could there be such a coincidence." ”

Jiang Lili was stunned when she heard this, and muttered, "The weather is cold?" I don't know if Mr. Chen brought thick clothes? ”

When the three girls next to her heard this, they couldn't help but worry.

……

Chen Fan walked out of the store, and Zhang Wenliang, who was waiting outside, couldn't help but be stunned when they saw him come out.

Zhang Wenliang stepped forward quickly, "Why is it so fast?" ”

Chen Fan raised the book in his hand, "You won't get lost inside, of course you will come out after buying it." ”

Zhang Wen leaned over and looked at it curiously, and suddenly frowned, "Mathematics, physics and chemistry self-study series? Do you still want to learn this? ”

Chen Fan smiled and said, "This is not for me to buy for myself, but for Xiao'e and them." ”

When Zhang Wenliang and Zhang Juemin heard this, they couldn't help but be stunned.

Chen Fan continued, "Although Xiao'e and the others are studying the content of textbooks in junior and senior high school, they are basically based on applied knowledge, and after learning, they cannot be said to be useless, but they are still very useful in their work, but they are also 'knowing what it is, not knowing why'."

Mathematics, physics and chemistry are the foundation of all natural sciences, and if the foundation is not laid well, it will be very difficult to learn more advanced knowledge in the future. If you learn this knowledge well, it will be easy to figure out the principle, and it will be much more convenient to learn other things when the time comes. ”

Zhang Wenliang and Zhang Juemin looked at Chen Fan, and couldn't help but feel a lot of emotion in their hearts.

I'm thinking about Lujiawan all the time, good guy!

At this time, the motorcycle rider next to him asked with a little hesitation, "Teacher Xiao Chen, I have a question I want to ask." ”

Chen Fan turned his head to look at him and said with a smile, "We've been together for a few days, so it's okay if you have something to say." ”

The rider smiled and said, "That's right, a motorcycle driver like me also has to repair the motorcycle by himself, but I can only repair my own motorcycle, once I wanted to repair the car on the unit, but I couldn't fix it, and many parts couldn't understand the function." Isn't this what you just said, the foundation has not been laid? ”

"Of course."

Chen Fan smiled at him and said, "You are the most typical principle that you don't understand, you can only learn the same from the master, and you will know the same." ”

The rider nodded again and again, "Yes, yes, it is the same to learn the same, to know the same, and not to learn it." ”

Chen Fan said, "But if you can learn the mechanical principles, then it will be very simple to learn the structure of the engine and the vehicle, and then look at other vehicles, even if you haven't seen them, you can understand them." ”

The rider immediately asked, "How do you learn the mechanics?" ”

Chen Fan shook the book in his hand again, "If you want to learn the mechanical principle, you have to eat this set of books thoroughly first." ”

The rider looked at the two bundles of books, muttered for two seconds, and then asked, "I'm in my twenties, can I still learn?" ”

Chen Fan said with a smile, "Don't say more than twenty, even if you are fifty or sixty years old, or even a hundred years old, as long as you are willing to learn, you can learn." ”

Hearing this, Zhang Wenliang and Zhang Juemin couldn't help but take two steps back.

Chen Fan glanced at them and continued, "And the threshold requirements for this set of materials are very low, and you can learn it after graduating from primary school." ”

The rider immediately nodded excitedly, "I graduated from junior high school, and the knowledge in the textbook is very simple, and I still remember a lot of it." ”

Then he gritted his teeth and said, "Teacher Chen, you wait for me, and I'll buy a set too." ”

After saying that, he walked into the door of the bookstore.

After a while, he came out, but his hand was empty.

Chen Fan was not surprised, and smiled at him, "No? ”

If this set of books were so easy to buy, they wouldn't have been sold at sky-high prices later.

The rider master nodded and said with a wry smile, "That's all they have in the bookstore, and it's gone when it's sold out." ”

Chen Fan laughed, "Yunhu is so big, and it's not the only bookstore, let's change places and go to other bookstores to have a look, and then go to the central bookstore, you can't just have this set in the whole Yunhu." ”
