Hong Tao originally took a fancy to a lot of things and wanted to buy them back, but first, the money in his pocket was a little tight, so he had to pick some things with a lot of appreciation space to focus on;

At the beginning, grandpa could bear to hide something in his house that Hong Tao got back every once in a while. But as there are more and more things, and the amount of money is getting bigger and bigger, grandpa finally can't help it, no matter how much he dotes on his children, he can't escape the shackles of the times, hundreds of dollars, just exchange for a bunch of old goods, and basically all of them are old goods that can't be used at home, and the old man began to talk to Hong Tao.

"Grandpa, have you ever played with antique calligraphy and painting?" Hong Tao could only explain his grandfather's accusation slowly.

"I haven't played it, that thing is played by the flag people, don't learn that, loser!" Grandpa didn't wait for Hong Tao to explain, and directly made a definition.

"Look, for example, the watch I bought, it will be worth tens of thousands of dollars in another 2o years, do you believe it? I'm not spending money indiscriminately, I'm saving money, it's more cost-effective than keeping it in the bank. Hong Tao continued to work hard, intending to impress the old man with numbers.

"Tens of thousands! That's a lot of food! It's just this broken watch, it's not as good as the one in my hand!" Grandpa still didn't believe it.

"This is different, just take your gourd, a gourd made of Sanhe Liu must be worth more than yours, right? The watch is the same, it looks like the same watch, but what I want is this size, the two watches I bought are like the gourd made by Sanhe Liu, the more you put it, the more valuable it is, you understand?" Hong Tao let his grandfather get out of the way, and suddenly heard the cicada in the old man's arms screaming, and found a good way to persuade grandpa.

"If you say that, you won't lose ......" After listening to the words of the little grandson, the old man finally understood, although he didn't know what investment was, but he understood the truth of the gourd.

To deal with grandpa, you can use interests to guide, but to deal with your father, you can't just talk about money, other things can be put in grandpa's house and not let your father know, but the multimeter still has to be taken home to use, Hong Tao can only buckle this basin on the head of the aunt, saying that the aunt and the electrician in their unit borrowed it.

"Well, it's a good thing that you like the radio, Dad supports you, but your starting point is a bit high, the radio is not so easy to make, just reading books may not work, your Uncle Wang teaches physics, why don't I take you to his house on Sunday, let him give you a lecture?" The old magazine didn't say anything, but I just felt that it was not suitable for Hong Tao to rely on self-study, and planned to find a teacher for him.

"Uncle Wang's things are too deep, I still don't understand, I'll learn a paragraph by myself first, and then go to Uncle Wang when I understand the basics." Hong Tao had a headache when he heard his father recommend his old friend, that Uncle Wang is a physics teacher at Normal University, and his father met when he was devolved to work, he is a good person, and he has no knowledge to say, in his last life, he bought parts by himself, and saved a 14-inch color TV for Hong Tao and his family, and later he also knew some patents.

However, this kind of researcher has a common problem, that is, his emotional intelligence is too weak, he is even weaker than Hong Tao's father, if you don't talk to him, he can look at the circuit diagram all afternoon without saying a word. In later generations, Hong Tao learned radio from him, and often stayed at his house for an afternoon, but he didn't think of you, and you must keep asking him all kinds of questions, otherwise you won't learn anything. Hong Tao didn't want to ask Uncle Wang questions for an afternoon like a curious baby, and now his knowledge was enough, and it would not be too late to go to him when he really wanted to save his own TV in the future.

"That's right, he's teaching you a little early, so I'll teach you, I probably know a little bit about it. Hong Tao's father felt that what his son said was right, he knew best what kind of virtue that Teacher Wang was, and he might not be able to teach his son these basic knowledge, so he planned to teach it himself.

"I'll see for myself first, and then ask you if I don't understand, I like to figure it out for myself. Hong Tao didn't dare to let his father teach himself, he understood radio theory, but only in theory, when he told you about the transistor, he turned to how to calculate the magnification of the transistor, and it was not a general talk, you had to understand those mathematical proof formulas clearly, as a result, you didn't learn radio knowledge, and learned a lot of mathematical formulas.

"Yes, you have to think about everything, you have to do learning like this, Cheng, you can see for yourself, if you don't understand, ask me again." "My father is satisfied, and what he likes to teach Hong Tao most is to have a heart that likes to ask why, and the will not to give up until he understands it.

The father didn't leave Hong Tao alone, he didn't know where to find several books about radio, and he didn't care whether Hong Tao could read or not, so he gave them all to his son, and then borrowed an oscilloscope from the real room of their school, which was used to let Hong Tao understand the changes in AC and DC waveforms more intuitively. For his son's study, he did his best, the oscilloscope was nothing in later generations, but in that era, it was a high-precision instrument, and ordinary units did not have it at all, even if it was in the university, he had to work hard to borrow it.

Not to mention that the father's emotional intelligence is not high, he is high and low, as long as it involves his son's learning or growth, he is willing to ask for help. At that time, there were a lot of good things in the university, such as borrowing skates from the physical education department, and then taking Hong Tao and Jin Yue plus his brother-in-law, that is, Hong Tao's little uncle, to go ice skating in Qianhai together;

Then get some mushroom strains from the biology department, let the mother take a bag of cottonseed skins, go to the high-temperature disinfection cabinet of the unit to disinfect, and then use iron wire and plastic cloth to make a small box with constant temperature and humidity, and let Hong Tao observe how the fungi turn from a few mycelium into a bunch of mushrooms.

Or get some chemical elements out of the chemistry department, and then do a small experiment in his study, tell him what electrolysis is, what will be left in the test tube after the magnesium strip is burned.

Although Hong Tao knows most of them, he still has to pretend not to know, and after listening to his father's explanation, he knows most of them, and then asks one or two more high-quality questions, and then asks his father to explain it, and finally understands all of them, and even goes skating Hong Tao has to pretend to fall several times before he dares to sway and skate by himself. At this time, Hong Tao can see that his father is smiling so happily, so heartily, and so fulfilling.

In order to make his father happy a few more times, Hong Tao felt that he should fall a few heels, pretend to be a fool, and make others happy, in fact, it is not too uncomfortable.

Anyway, Hong Tao is still quite satisfied with his current small life, except for going to school in the morning to suspend classes is a little boring, the food is a bit monotonous, and there are no amateur entertainment activities, everything else is not bad, at least he feels that relying on his own ability, he can live a relatively good life in this era, and he can be content to be happy.

Winter goes to spring, another Spring Festival has passed in a blink of an eye, and the time has entered 1978, when the sky is full of poplar catkins again, Hong Tao is already 6 years old. In less than two years, his height has risen a lot, has passed 1.3 meters, almost taller than children of the same age, although the body is still emaciated, but it is not as thin as a bamboo pole, at least the chest is no longer a small rib, arms and legs are also well raised, due to long-term exercise, the muscles there feel much harder than children of the same age. The only drawback is that it's a little dark, and it's no wonder that Hong Tao is not blamed, he is not white by nature, plus he always runs outside all day long, sunburning.

To Hong Tao's surprise, Jin Yue actually grew to 128 cm tall, it seems that those catfish really worked, he remembered in his last life that when the two of them went to elementary school together, the top of Jin Yue's head was only up to his shoulder. Although it is said that girls are born earlier than boys, this obvious change is certainly not explained by light education.

In fact, after the Spring Festival in 78, Hong Tao stopped the catfish, and instead of the catfish meat, it was two eggs a day, and then in a week or so, the aunt-in-law would send a chicken, a rabbit or a large strip of pork belly to their family. He really couldn't eat the oily catfish meat, and before dinner, he began to vomit unconsciously.

These eggs and meat are bought by the eldest aunt from the countryside, and since this year, more and more people have gone into the city to sell things, not only in the fringe areas of the city, you can see people pushing wooden carts and riding bicycles to sell agricultural and sideline products, sometimes they will also appear in the alleys, and the most people exchange eggs for food stamps, as well as for peanuts, melon seeds, and tofu shreds.

Hong Tao has been paying attention to the movement in the newspaper, last year the chief designer has been co-opted as a member of the Standing Committee, in May this year, he has seen the Guangming Daily published in the article "Practice is the only criterion for testing the truth", he knows that the change of the times is coming, but when will it come, he has no score in his heart, so that he has never cared about this thing in his previous life, and the political lessons learned in school have also been returned to the teacher.

However, looking at the current form, the countryside has begun to quietly loosen, although the upper strata are still carrying out the final struggle, but the common people below can no longer bear it.
