Yongping, summer has come, the river by the Li River has risen again, Ding Zi and Yang Qingyun sat on the embankment, looking at the rushing Li River and neither of them spoke for a long time.

"Qingyun, time flies too fast! The world has become too fast! We were here this season last year...... At that time, I wasn't very familiar with it, and you were still practicing the 'temporary Buddha's feet' magic skill, and I ...... I'm also very distressed, I didn't think about going to Yan Da ...... at all."

"Yes, the only constant in this world is change! But the good news is that everything is changing for the better.

At this time last year, I really didn't dare to think about Shonan University, but fortunately, Master You, passed on the skills, otherwise I wouldn't know where to draw circles now!" Yang Qingyun said.

Ding Zi pursed her lips, looked at Yang Qingyun with a pulse, and said, "I don't have anything else to go to the United States, I just feel empty, inexplicably uneasy, and uncomfortable!"

Yang Qingyun gently patted Ding Zi's back, and his mood was also complicated. How to say it, it's hard to express it in words, because Yang Qingyun has experienced 20 years since 2000, but anyone who has had that experience should not have too much good impression of the other side of the ocean.

From an emotional point of view, Yang Qingyun is extremely disgusted with going abroad, but people are rational, think carefully about the 99 years of China, students studying economics and financial investment, it is really the environment can not help a person climb the peak of dreams.

So it's definitely a good thing that Ding Zi can go abroad, it's just ...... Yang Qingyun was deeply resistant to going to the United States and taking the TOEFL test! This is the root of his inner complexity.

No one in this world can be completely rational, and Yang Qingyun really has no way to do it, so after Ding Zi goes abroad, the two may not be able to see each other for a long time.

"Let's go, didn't you say it's good to sing?" Yang Qingyun said.

"Hmm, wait a minute!" Ding Zi didn't want to leave, the two were tired of being together for several days, and they said a lot of things. The cognitive world of the two knew that it was necessary for Ding Zi to go abroad at this time, and this was already a consensus.

As for saying that life is short, when the day is short, and so on, that is even more clear to each other. But sensuality is too powerful, so strong that Ding Zi is so free and generous, and now he loves to cry every day.

Especially when the two K sang the lyrics "I want to transcend this ordinary life, I am destined to be temporarily adrift now, and I can't stop my inner fanaticism and attachment to the future", Ding Zi will collapse directly.

The world is changing, and the only constant in everything is change, so there will be no eternal love in this world, and there will be no sea and rocks, just like in the past year, both Ding Zi and Yang Qingyun have changed dramatically.

Ding Zi doesn't know if he will suddenly become unaware of the way home after he arrives in the United States, and whether the relationship between the two will have a good home in the future?

I really don't know now, everything is unknown, maybe something really happened, and I won't feel like anything at that time. But at this moment, Ding Zi wanted to cry, she was reluctant to part with her lover, things were as simple and simple as that.

After staying in Yongping for two days, after the two returned to Star City, Chen Bo and his family, Ding Zi and Yang Qingyun, as well as Si Qiao and Zhang Mi, had dinner together.

After the dinner, Yang Qingyun sent Ding Zi to the airport, and after arriving at the airport, Yang Qingyun held Ding Zi's cheek and said, "Go back, isn't there still more than a month to leave?

Also, it will be more convenient to go abroad after next year, and I will strive to earn more money so that I can probably afford to go on vacation to the United States every year, and then I will easily go over there to see you!"

Ding Zi smiled and said, "I'm very happy if you make me happy! I hope you can do what you say......

"Okay, let's go back! Didn't Chen Bo and Si Qiao make an appointment with K Song?

Yang Qingyun shook his head and said: "I won't sing, I have to go back to the electronic design competition, there is only one week left to come up with the project, and now I haven't skimmed the eight characters yet!"

"Then work hard! I'll go back to Beijing to go to the library, what's the matter with the love of children? We should spur our horses and weave a splendid future!" Ding Zi laughed and rushed to the security checkpoint like a rabbit......

……

Ma Liguo has been walking to the No. 3 dormitory building every day for the past two days, and as a student living in an apartment, the No. 3 dormitory is dirty and messy in his eyes.

Isn't the squad leader quite rich, he has mobile phones, why is he so slamming the door on top of his apartment? Really......

"Oh, Grandpa Ma is here again!" Ma Liguo walked downstairs, Shi Jie in the dormitory was in a weird manner, a group of brothers laughed, Yang Qingyun hurriedly said: "Shi Jie, look at your stocks, can you accumulate some virtue?"

"I'm just talking between our brothers, but in the eyes of Ma Gonggong, it's just Boss Yang, you and him, we are all third-class citizens......!

Wei Lizhong pinched an orchid finger and made a charming expression and said, "He said that the public toilet stinks......"

"I almost threw up that sissy at the time! What are you pretending to be? Such a person, isn't he going to come over and carry straw shoes for our Yang boss?"

"Shhh

"Squad leader, I've got all the materials you want!"

Yang Qingyun pointed to a chair for him to sit on, and then began to carefully look at the results of Ma Liguo's project during this time.

Ma Liguo has prepared two projects for the electronic design competition, one project is the intelligent electric car project, which uses a single-chip microcomputer to control the car to achieve obstacle avoidance, acceleration, deceleration, cruise and other functions.

The second project is a sampling system, which is mainly an electronic project designed for the specific application of an integrated circuit, and this project is an application project designed for the TLC5510 chip of Texas Instruments.

"Squad leader, the two projects are one difficult and one easy, the car project emphasizes the use of several modules to achieve specific functions, and it is more difficult to do it! The second project we directly build application circuits for chips to achieve specific functions, which is simple and easy to implement, and even we can ......make finished products by using the current laboratory ourselves."

Ma Liguo talked eloquently, staring at Yang Qingyun with a blank eye, it is obvious that he wants to get Yang Qingyun's affirmation, you must know that he has also worked hard for this electronic design competition, in addition to last year's winter vacation to review professional courses, he also specifically consulted the various entries in the national electronic design competition since 94.

He summarized and summarized these previous entries according to these previous projects, and finally thought of these two topics, which should be said to be relatively reliable!

But Yang Qingyun's face was expressionless after reading it, no, the first thing made by the topic is the level of electronic car toys for three-year-old children, and although the second project can be done, it is relatively simple, and it may be possible to compete on the campus of Shonan University, but after all, it is still too simple, and it is almost impossible to get results!

"Squad leader, can't you?" Ma Liguo said, feeling a little unconvinced, after all, these projects are his hard work, so he can be convinced?

Yang Qingyun said: "Ma Liguo, it's good that you can come up with these projects! I guess you have read the projects of the electronic design competition in previous years, so as to combine your own knowledge to make these two projects."

I think the best result is the level of toys, infrared communication and single-chip sensor obstacle avoidance, this product has long been rotten, and even the circuit diagram may be directly purchased from the toy car factory!"

Yang Qingyun pondered for a moment and continued: "As for the second project, I think it's good, but it's too simple! Your project is only based on the application-level design of a Texas Instruments chip in the United States, and the result after this design comes out can only focus on participation, right? We want to compete and get the ranking, it's almost impossible!"

Ma Liguo was stunned for a moment, he didn't speak for a long time, he was running at high speed in his mind just to refute Yang Qingyun, but after thinking about it repeatedly, he still felt that Yang Qing was reasonable, and he had no way to refute it.

This feeling made him feel a little discouraged, but then he thought that since Yang Qingyun was not optimistic about his project, what good project could he have?

"Squad leader, then what do you want to do! If you have a project in your hand, I will fully support you!" Ma Liguo said, he looked at Yang Qingyun, and Yang Qingyun was also thinking in his mind, suddenly he clapped his hands and said:

"There you have it, there's a project that you can!"

"Ma Liguo, didn't you buy a computer? When you use the computer to play music, play MP3 files, right? We can design a set of three-in-one MP3 player with storage, lithium battery and decoding processor. ”

As soon as Yang Qingyun mentioned this, the whole person suddenly became excited, and he remembered the boom of MP3 players after 2000, at that time, this thing was simply a complete subversion of the traditional Walkman!

The current Walkman, such as the one brought by Ma Liguo, is a high-end product from Sony, but it is still the size of a slap and relatively heavy. But after the MP3 player came out, it completely subverted the product of the Walkman, the size of a matchbox, which can store hundreds of songs, which is a revolution in the practical application of electronic technology.

"Don't you understand? No matter how much we change the Walkman we use now, we can't change the mechanical setting in it! You listen to the cassette, the motor drives the cassette to rotate, and this is the mechanical setting. With this thing, we can't make the Walkman smaller!

In addition, the size of the cassette is also fixed, so we want to be more convenient to carry the Walkman with traditional technology is no longer enough.

But MP3 players are different, we store MP3 format files through flash memory, and then decode the output through the integrated processor, and we use the lithium battery technology of the mobile phone for power supply, which is definitely a subversive technology.

This technology first subverted the iron rule that the Walkman needs a mechanical setting, and we can guarantee that our products can be the size of a fingernail and play for hours at a time......"

Yang Qingyun excitedly explained the principle of MP3 player to Ma Liguo, and the brothers in the dormitory were stunned by his speech, most of them couldn't understand it, but it couldn't hinder their imagination.

You must know that at that time in 99, everyone's entertainment method was far less than modern, at that time computers were still luxury, there were no smart phones, Internet cafes were mainly chatting QQ, and there were no online games.

The most popular place in the school is the rental bookstore next to the cafeteria, and the pursuit of the highest level of music by the young people is still at the level of a high-end Sony Walkman. Now that I have bought a computer, adding a speaker to be able to play music is already a very awesome technology product.

If it is really as Yang Qingyun said, it can make a walkman that is only the size of a matchbox and has the effect of high-end sound quality, then ...... That would definitely drive a lot of enthusiasts crazy.

In fact, when MP3 first came out, the price was as high as several thousand yuan, and many people smashed the pot to sell iron and bought one in their hands, this thing has been popular for several years!

The decline of MP3 is due to the rise of smartphones, which directly integrate music playback functions, and this product has withdrawn from the stage of history.

"Boss Yang, although I don't understand, but I think it's very awesome! I support you! If you can really make a product, you have to send me one!" Shi Jie stretched out his thumb and said with a cheap smile.

"I think it's awesome, but I don't understand it!"

"I don't understand, boss, we don't seem to be studying a major, are we?" Wei Lizhong also said.

When he arrived at Ma Liguo's place, but seeing that his brows were deeply furrowed, it was obvious that he was digesting Yang Qingyun's words, what kind of self-esteem did he have? No matter what, he couldn't say that he didn't understand!

But some people are not happy to look at it, everyone in the dormitory doesn't understand, what kind of big tail eagle are you Ma Liguo? frowning like constipation, really think you can keep up with Boss Yang's train of thought?

"Actually, some people don't understand, but they just don't know how to pretend to understand, like our brothers, if they don't understand, they don't understand. Generous, frank and open, Boss Yang, don't you say?" Shi Jiesao said.

Ma Liguo's face turned red, and he couldn't help but say: "Who are you talking about? Who doesn't understand? I can understand it! The computer actually realizes the same function as an MP3 player when it plays music, but we just want to make a special playback hardware now, why don't I understand?"
