The next day, Yang Feng got up early in the morning, and every morning at five o'clock was when all the bedrooms were powered up. So in order to be able to turn on the computer for the first time to test the equipment, when everyone was still asleep, Yang Feng got up at four o'clock to run. It was a little cool in the early morning, and Yang Feng was running around the playground in his school uniform, sweat already soaking through his vest. The early morning sun is a little shy, did not dare to show their faces, because the actions of human beings at night do not pollute nature, so the air is exceptionally fresh, although those faint sunlight sprinkled throughout the city, the tone of the whole city is still a little cold, through the early morning air, the surrounding buildings and high-rise buildings are a little blue.

Yang Feng was reciting the core instructions of the programmable switch while running, and the white haze was exhaled rhythmically with Yang Feng's footsteps.

After a simple run, Yang Feng was already in good spirits when he returned to the dormitory, and after nearly 40 minutes, the students in the dormitory were still asleep. At this time, he picked up the blue thermos and plastic basin and walked to the water room, first poured the biting cold tap water, and then tested the temperature of the water with his left hand again, while pouring hot water into the basin with the thermos, and along the hot water, a cloud of white gas rose. "Bang bang bang", he simply washed his head and face and returned to the bedroom.

Back in the dormitory, he wiped his face and head with a towel, put on a new vest and socks, plugged in the power of his computer and equipment, and waited for the moment when the call came at 5 o'clock.

As soon as the light came on, he knew it was coming. The second and third children were stabbed in the eyes by this light, so they closed their eyes, hugged the quilt, turned their heads to the other side and fell asleep. Seeing this, Yang Feng walked to the position of the light switch in the bedroom and turned off the light so that the brothers could sleep well. He then sat down at his computer and connected to the Internet, and began to look up more advanced usage of routers and switches.

Because the fans of the router, switch and Yang Feng's laptop were loud, the other brothers were woken up by the noise, rubbing their eyes one by one, as if they hadn't woken up, and silently went to the water room to wash.

Yang Feng flipped through almost all the materials he could read on the Internet, and he already knew the technology of routers and switches, so he pondered how to make the bald uncle able to maintain himself in the future. So he thought about it for a while, and suddenly he decided to write a few pages of concise tutorials, so that the uncle could restore the device to factory settings by himself in the future.

Just do it, Yang Feng picked up the pen and began to record the steps to solve this problem on the paper, in order to be more concise, the recorded content is all written in accordance with the first step, the second step, and the third step of the operation steps, and why it is handled like this, is not written on the paper. If written in this way, even ordinary people who don't know anything about computer networks can easily follow the steps to operate. If such a tutorial is placed now, it is generally called "best practice", and often if a software engineer does not have a theoretical foundation to study a problem thoroughly, there are often some god-level figures who write some tutorials, so that beginners can quickly feel the new technology.

In the morning, Yang Feng called the bald uncle at the end of the third class: "Hello, I am the high school student we met in the computer city yesterday, the equipment has been repaired, can you come and pick it up?"

And the bald uncle never thought that a high school student would be able to repair both devices, and he felt that he was really not wrong about this young man, and the smile on his face could be seen through the signal of his mobile phone: "Okay, I'll leave now and go to your school."

At noon, Yang Feng called the brothers in the dormitory to move the equipment to the door of the school, and sure enough, the bald middle-aged man he met yesterday appeared, but the situation was a little embarrassing.

A traffic policeman had just taken a photo of the uncle's car, and when he was about to issue a ticket, the uncle said to the police: "Dude, do you think this is good, I'll stop here for a while and drive away immediately."

The traffic police saluted the uncle with a serious face and said, "I'm sorry, do things according to law." The entrance of the school is a no-parking area, and there are no-parking signs on the roadside, and a penalty of 200 yuan will be deducted 3 points. You see that these four rows of lanes have become two rows, and there will be traffic jams for a while, please cooperate with my work and evacuate here as soon as possible, so as not to affect the traffic. ”

Then the traffic police tore off the ticket and handed it to the bald uncle, and then took the camera to deal with the next illegal parking. The uncle silently stuffed the ticket into his jacket pocket, and this scene was hit by Yang Feng and them.

At this time, Yang Feng walked up to the uncle with the router in his arms and said, "I'm sorry, you were fined."

The uncle saw Yang Feng's upright personality and smiled: "The fine is not unjust, I am at fault first, and it is not bad for you." Then he opened the trunk of the car and said, "Just put the device in the back."

At this time, the second child held the switch and put it in the trunk, and Yang Feng took out a folded piece of paper from his trouser pocket and handed it to the uncle. Uncle took it and looked at it. Yang Feng explained: "This is the factory reset steps of routers and switches, if you encounter a problem next time, you can quickly restore it by writing on paper", as he was talking, he took out the self-made CONSOLE cable from his pocket and handed it to the uncle: "This is the terminal cable I made myself, and I can use it when I restore factory settings."

In addition to being surprised by Yang Feng's skills, the uncle was also moved by his uprightness and sincerity: "There are really not many young people like you who have good skills and are so careful now!"

Hearing someone praise himself, Yang Feng couldn't help but smile. At this time, the bald uncle took out 100 yuan from his wallet, and handed Yang Feng's student ID card to Yang Feng from his coat pocket: "Little brother, take it quickly, and deduct your student ID for a day, I'm really embarrassed."

Yang Feng hesitated for a moment and said, "I can't collect this money, you were fined just now."

The uncle smiled: "One yard to one yard, this is what you deserve". The third child saw that the bald uncle took out a hundred yuan, but Yang Feng still didn't accept it, so he stepped forward and took the hundred for Yang Feng, and said: "It's better to be respectful than to obey your fate, and it's not strange to be polite to many people", seeing Yang Feng's brother take the money away, the uncle also felt relieved, and walked to the driver's seat, while saying: "Little brother, I'll go first, and I'll be fined after a while, and there will be a period later."

In just a few seconds, the uncle stepped on the clutch, put on the gear, let go of the handbrake, turned the steering, stepped on the accelerator, and walked away.

Yang Feng and the second child glanced back at the third child one after another, with a slight disdain in their eyes. The third child quipped: "A hundred! How many delicious foods can you eat!", and his face was timid. Seeing that the third child looked confused, he was so cute, and both of them laughed. Yang Feng put one hand on the third child's shoulder: "It's just noon, and the newly opened Malatang in front of me is good." Let's go!", the third child hummed a limerick: "Follow Brother Yang, eat and drink!"
