Sanjiang in 1990, the early morning of winter - it is a bit inappropriate to say that it is early morning, because it is only four o'clock in the morning, this season, this time, when many people are still sleeping in the warm bed, Feng Xiaotian has already gotten up.

Feng Xiaotian is an orphan, when he was six years old, his parents died in a car accident, and then he lived with his grandmother, who was a very amiable person, for this most beloved grandson, she would get up early every day to pick up garbage to maintain the family's life, but unfortunately, five years ago, the elderly grandmother also died of illness, so the family is currently the only one left Feng Xiaotian.

Feng Xiaotian is not without relatives, but those relatives are relatively indifferent, even when Feng Xiaotian's grandmother passed away, they didn't come to take a look, and it can be said that there is no family affection at all.

At a very young age, Feng Xiaotian learned to be independent, and compared with his peers, he lost his parents at a young age, which made him sensible overnight, and in his eyes, this world seemed to have lost its color overnight, and it was all gray.

"Whew-"

Feng Xiaotian got up from the bed, the weather was too cold, Feng Xiaotian just lifted the quilt, the heat in the quilt disappeared without a trace, Feng Xiaotian was wearing a shabby autumn coat, there were quite a lot of patches on it, even so, Feng Xiaotian also cherished it very much, because this was one of his only two sets of autumn clothes, although these two sets of clothes were left by his father, and they looked a little fat on him, but in terms of the current situation, it was already very good to be able to wear autumn clothes.

Feng Xiaotian quickly put on his coat, the army green coat was very shabby, but it was very warm, and it was full of fluffy fur, after putting on the coat, Feng Xiaotian finally breathed a sigh of relief.

After washing up with the biting cold water, Feng Xiaotian went out with a snakeskin bag, and he was going to beg for a living - that is, to pick up garbage.

Feng Xiaotian is 14 years old this year, and picking up garbage is a familiar thing for him, for several years, he has been doing this every day, no matter the wind or rain, he has never stopped, because otherwise, he will have no source of livelihood and will starve.

Feng Xiaotian took out black cotton gloves from the snakeskin bag and put them on, and after locking the door, he strode out into the street.

It's dark outside, and even if there are street lights in this era, it's impossible to keep them on all night, and the residents' electricity consumption is not satisfied, so where can it be so wasted?

Feng Xiaotian walked forward in the dark, when passing by a garbage heap, he stopped and rummaged in for something, although he couldn't see it clearly, but with his many years of work experience, he could also roughly perceive the shape of the items in his hand, what can be sold for money, what can be kept for his own use, Feng Xiaotian is clear, soon, this garbage heap was swept by him, Feng Xiaotian only harvested two wine bottles, it seems that today's outing color is not very good.

Feng Xiaotian continued to walk forward, every time he passed a garbage heap, he would stop and repeat the action of rummaging, as time passed, the snakeskin bag in his hand slowly bulged, and by half past six in the morning, the snakeskin bag finally could not hold anything.

Feng Xiaotian was satisfied with the snakeskin bag on his back and walked to the scrap recycling station, along the street near the high slope of the vegetable market, there is a waste recycling station, when Feng Xiaotian carried the snakeskin bag to the door of the recycling station, the owner here is squatting under the wall in the courtyard to brush his teeth.

Feng Xiaotian pushed open the courtyard door and walked in, with a smile on his face: "Uncle Li, you got up so early on such a cold day." ”

Uncle Li is a little old man in his sixties, his hair is messy like a chicken nest, and his beard is scummy, others call him Lao Li, and as for his real name, few people know it.

Hearing Feng Xiaotian's words, Lao Li rinsed his mouth, stood up and said with a smile: "Where am I early?" Didn't you predate me? Xiaotian, you wait first, I'll wash my face and come out. ”

After Lao Li finished speaking, he walked into the house, Feng Xiaotian agreed, bent down and poured his morning's harvest on the ground, and then he sorted out these things in different categories, and when Lao Li came out, he smiled and said: "Uncle Li, come and count." ”

Lao Li nodded with a smile when he heard this, he held a scale in his hand, first bundled the waste cartons and newspapers picked up by Feng Xiaotian, and after weighing the scales, he said: "Waste paper has a total of five catties and four taels, five cents a catty, five five twenty-five, four taels is two cents, and it adds up to a total of two cents and seven." ”

After Lao Tzu finished speaking, he put the waste paper aside, and then picked up a broken pot, and after weighing, he said: "This pot is two and a half catties, calculated according to three cents and one catty, two or three get six, and half a catty is one and a half catty, adding up to a total of seven cents and five - look at these plastic ...... again"

In less than five minutes, Lao Li finished counting the things Feng Xiaotian picked up, and after calculating the price, he smiled and said: "Xiaotian, your harvest today is good, all the things add up to a total of six cents and three, this is money, you take it." ”

Feng Xiaotian took the money, carefully put it in his pocket for safekeeping, and then smiled: "Thank you Uncle Li, you are busy first, I'm leaving." ”

After Feng Xiaotian finished speaking, he turned around and walked out, but when he passed by the recyclables piled up in the courtyard, his eyes were attracted by one of the strange iron boxes, only to see him stop, lower his head and carefully look at the iron box, his dark eyes motionless.

Seeing this, Lao Li smiled and said, "I took this thing back from the university town last night, and a doorman sold it to me, and he said it was ...... What is it? - Anyway, I don't understand what kind of equipment is obsolete from the school. ”

Feng Xiaotian opened his mouth when he heard this: "Uncle Li, how much did you spend on this thing?" Can you sell it to me? ”

Feng Xiaotian was a little excited at the moment, because he knew what this iron box was, he had only seen this kind of thing in books, and it was the first time he had seen it in reality.

Lao Li blinked when he heard this, and asked a little puzzled: "Xiaotian, what do you want it for?" I think it's similar to scrap iron, so when recycling, it's calculated according to the price of scrap iron, a total of ...... Two pieces of one, right? How? Do you really want to? ”

Feng Xiaotian nodded again and again when he heard this, he suppressed the strong restlessness in his heart, and said in his mouth: "Uncle Li, why don't you sell it to me?" ”

Feng Xiaotian was afraid that Lao Li would raise the price, so he tried his best to control his tone and make his tone sound calm, Lao Li looked at Feng Xiaotian, and then looked at the iron box, and after a while he smiled and said: "It's okay to sell it to you, but this is what I dragged back from the university town, and it took me a lot of effort to travel more than 20 miles, so let's do it, I'll add a little hard fee, and charge you two yuan and five fine, do you think it's okay?" ”

Feng Xiaotian pretended to hesitate when he heard this, hesitated for a moment before he took out the money from his pocket, and after counting the amount, he handed the money to Lao Li's hand, and said in his mouth: "Uncle Li, this is money, you can order it." ”

Lao Li Xiao made a fortune, and smiled again and again: "No need, when did you miss it?" ”

Lao Li's face bloomed with joy, the collection of rags was originally to buy low and sell high to make a difference, this iron box was shipped back with other things, said that it took a lot of effort, this is completely a means of raising prices, two yuan and one bought things sold for two and five, according to the income ratio, it is still very considerable, Lao Li has been operating this road for many years, naturally it is very clear, so he is so happy.

Happy people will inevitably get a little carried away, so Lao Li continued: "Little God, there are two other things that are recycled with this thing, do you want them?" ”

Feng Xiaotian's eyes lit up when he heard this, but soon he pretended to be confused and said, "Oh? Something else? Can you show me? ”

Maybe Lao Li still wanted to make a fortune on Feng Xiaotian, so he seemed very enthusiastic, and I saw him say with a smile: "The thing is in the house, you can go in with me and have a look." ”

Feng Xiaotian followed Lao Li to the house, and he had already guessed what those two things were, but his face was silent, and he couldn't see anything unusual, and when Lao Li pointed to the two things in the house and spoke to him, Feng Xiaotian couldn't hear any words.

- This is a computer, the iron box outside is the host of the computer, and the two things in the room are a computer monitor, and the other is naturally a keyboard.

In this era, computers are quite rare in China, and many people have never even heard of such a thing, but Feng Xiaotian knows a lot about it, because he picked up a book when he was picking up garbage, which is a book about computer knowledge, and the title of the book is "Computer Programming Languages and Programming".

Feng Xiaotian is still a teenager, and he is naturally very curious about new things, and when he first picked up this book, he was deeply attracted by the title of this book - computer? Is this a book about computer literacy?

The book was eventually kept by Feng Xiaotian, and he would read it every night, and his curiosity about the amazing thing of the computer had already reached its peak, and the most incredible thing for him was - how did the computer execute instructions? How do people give computers such magical abilities?

After Feng Xiaotian's study, he finally understood the truth of this, for computer programming, he also has his own unique views in theory, today he saw the computer host, his strong curiosity was instantly promoted to the top, if you can have a computer, wouldn't it be from theory to practice?
