"My little comrade, please open it and try to fix it. This is an old problem. We asked the salesperson last time, but they didn't understand it either!" The old lady looked at He Ku with anticipation and said slowly.

"That's true! I'll help you see, I still understand a little bit of this thing."

With the old lady's approval, why bother turning on the radio in just a few seconds. The whole process was easier than expected. Apart from the four fixing screws, there was no other fixing method.

Place the screws on the seat next to it and slowly turn on the wooden back shell of the radio.

This process is also quite easy. When the rear case is halfway open, He Ku discovered the problem. It turned out that a power cord was blown into two pieces.

This is probably the cause of the failure. It had not been completely burned out, and there was a little copper wire connected, but after the old lady took a photo, the copper wire connected in the end was also broken, which led to the final damage to the radio.

"Little comrade, how about it?" At this time, the old lady looked at the situation inside the radio with curiosity and asked softly.

"There is no big problem. I thought it was a false welding, but it was actually just a blow-off. Just connect it again!" He smiled bitterly, connected the burned two ends together, and then took out a little insulating tape from his pocket to cover the repair position.

It is worth mentioning that why just wrap the tape around for a while without too much.

After all, at this time, tape was still a precious thing, and if you use it too much, it would seem like a waste of money.

Put the wooden back cover on, why not tighten the screws as soon as possible, but choose to try it first.

"how?"

"It should be no problem!" Under the expectant gaze of the old lady, He Ku pressed the button.

Suddenly, a melodious female voice suddenly rang out, and the sound was very loud. It was obvious that the sound was very low before repairing it, and the old lady turned on to the maximum volume.

While listening to the opera, slowly lower the volume.

Yu Ji (female voice) - Since I followed the king to fight in the east and west, I have suffered from wind and frost and hardship year after year. I only hate that the Qin Dynasty has ruined the lives of the world, which has only caused the people to suffer.

The soundtrack of the supporting music - The king is back to the camp!

Xiang Yu (male voice) - The gun was picked out by several generals in the Han camp. Even if he was brave, how could he be wary of burying them on all sides? It was said that the general ordered Xiu to send troops to the camp.

Yu Ji (female voice) - King ~!

Xiang Yu (male voice) - How panic will you be caused by this influx.

Yu Ji (female voice) - King, what is the outcome of the battle today?

Xiang Yu (male) - A gun was used to pick several generals in the Han camp, but the enemy was too small and it was difficult to win. This is because the heavens destroyed our Chu, not the crime of war.

......

"Okay? Thank you, boy!"

Seeing that the radio had been repaired, the old lady smiled so hard that the wrinkles on her face became deeper.

"Not yet, I'll install the screws for you!" He Ku said, and he was about to get the screws.

But halfway through, He Ku suddenly thought of something, took off the back cover and looked carefully.

Logically speaking, the materials used for the copper wire just now were extremely luxurious, and I don’t know why it fuses.

If you don't figure this out, you might have to be bad!

Then, He Ku started to check the problem. After searching on the circuit board, he suddenly found that there was a missing capacitor in one position.

I don’t know if it didn’t happen when it left the factory, or it dropped in the middle. In short, this will affect the stability of the power supply current!

Then, He Ku took out another capacitor with a good resistance value and inserted it, and made a simple reinforcement.

Looking at the action of the slightest, the old lady asked, "My little comrade, how much should I give you?"

"No money, it's okay!" He Ku shook his head and prepared to install the back shell.

The old lady said in surprise: "How can you be so embarrassed? You have also done the work and materials, so how can you not charge money? Isn't that a loss?"

Why waved your hand, "It's okay, a resistor doesn't even cost a cent, why do I have the nerve to collect the money?"

"This is not possible. If you don't have this cent of money, the radio will definitely be replaced!" As he said that, the old lady began to look for money on her.

Now, He Ku had already put the screws on and returned the radio to the old lady, and stopped her behavior. "I'll be angry if you do this, it's a simple task!"

"Young man, be obedient, take it!"

Why shook his head and refused firmly. Those who could live here were all soldiers' families, so I was embarrassed to collect money.

I couldn't do anything, so the old lady had to give up. After taking the repaired radio, she looked happily for a while, and then asked embarrassedly: "Young man, thank you so much! Can you tell me how to repair this radio? Many people in our yard have this problem, and I want to help them repair it."

"What, what else is this?" He Ku was stunned.

There is a problem with one or two radios, and it can be said to be a malfunction, but if there is a problem with one compound, it is a design problem!

Could it be that the Peony Radio missed this capacitor while copying the work?

Why bother to think about it?

After a pause, he replied: "Grandma, this thing is very complicated. The problems that may arise on each radio may be different. There is no way to teach you in a short time, but if there is a problem with the power supply wire, you can try to connect it yourself, but the others depend on the specific situation!"

"However, I just have time today. You can call the people in the yard to come over and I'll help me repair it."

"Really!" said the old lady in surprise.

He Ku nodded solemnly and said, "Really, even if I can't finish repairs, I can still help send them to Mudan Radio Factory for repair. I am a part of Mudan Radio Factory. I can negotiate with Mudan Factory to help solve the problem of radio quality assurance."

The old lady asked in confusion: "What is the warranty?"

"It's just that it's broken and it's for cultivation!" He Ku explained simply.

The old lady said stubbornly: "Oh, this is great! If there is no warranty, we will not know who to repair it if it breaks! We can't even get into such an important factory in Peony Factory."

"Little Brother Ku, why did you come here?"

At this time, Nie Xiaoya's voice suddenly came from behind He Ku.

"I just wanted to find you, and then I met this old lady here, so I chatted for a few words." He Ku said.

Nie Xiaoya nodded, and after seeing the old lady, she smiled and said hello, "Hello Grandma Hua, I'll take Xiao Ku brother back first. If you have anything to do with Xiao Ku brother, you can come to my house to find him."

Grandma Hua replied with a smile: "Okay, okay! Go quickly! If Xiuyi meets the little comrade, she will be satisfied with the custody."

"Goodbye Grandma Hua!"

"Goodbye little comrade!"

...

On the way, Nie Xiaoya asked curiously: "Do you know Grandma Hua?"

"Well, I just met you!" He Ku nodded.

"Oh oh!" Nie Xiaoya nodded, and hurried back with a hurried look. "Then let's go back quickly. I just found my grandma, so I hurried to buy vegetables. I forgot to tell you. As a result, the service club has nothing, and it's not as good as the things in our new factory!"

"The conditions for the new factory are still very strong!"

He Ku replied, and the two of them came to the Hongqi cart, took off the local specialties, went to the third floor, and came to Grandma Nie Xiaoya's house.

I knocked on the door, and soon, an old man walked out. The old man looked very kind and had a smile on his face.

Although she is about the same age as Grandma Hua, she is much more energetic than Grandma Hua.

Moreover, judging from the way I walk, not only does it not hunchback, but it is also very fast.

Nie Xiaoya hurriedly pulled Heku into the house, pointed at Heku and said to the old man, "Grandma, this is the little brother I told you. We are classmates and colleagues."

Nie Xiaoya's grandmother looked at Hekuo and pulled him to the sofa in the living room. She kept holding Hekuo's hand and asked and answered in a familiar way: "Young man, how old is this year?"

"22." Why answer?

As soon as this said, Nie Xiaoya's grandmother quickly said: "Oh! It's not too young, it's time to get married, Xiaoya is 22, you are not young anymore!"

"Uh! Yes yes!" He Ku smiled awkwardly.

"Xiao Ku, how many months did you give birth to?" Soon, Nie Xiaoya's grandmother asked again.

"One month." He Ku glanced at Nie Xiaoya with an unnatural face and replied.

Nie Xiaoya's grandmother smiled again, "Come on, Xiaoya is in December, and you two happen to be the end of the year."

Hearing this, Nie Xiaoya said embarrassedly: "Grandma, I haven't had a drink of water yet when I entered the house! You just keep asking."

"Look at my memory, Xiao Ku, drink water, drink water." Then, Nie Xiaoya's grandmother picked up the teapot on the tea table, poured a cup, and handed it to He Ku.

"Thank you grandma." He Ku said thank you and drank a little water symbolically.

However, as soon as He Ku put down the cup, Nie Xiaoya's grandmother asked again: "Is anyone in your family a soldier?"

"Uh!" He Ku was stunned for a moment, and then replied: "My father, my grandfather, and my great-grandfather have all been soldiers, but they have passed away."

"Diet?" Nie Xiaoya's grandmother suddenly looked dark, and then she continued: "You have suffered so much for the years! It's not easy for you and your mother."

He Ku was silent for a while and said, "Well, she passed away, but we have never suffered any hardships. With Guo Jia's subsidy, we live a good life. And when my great-grandfather and others passed away, I was already in college and started working not long after."

"What?" As soon as this said, Nie Xiaoya's grandmother was stunned, and then asked incrediblely: "Is your great master named He Shanlin? He was the commander of xxxxx when he was aiding Korea!"

He thought about it, shook his head, and said conservatively: "I don't know if it is the xxxxx teacher. My great master has never mentioned it before, but my great master's position is also the commander."

"Did you grow up in the military district dean?" Nie Xiaoya's grandmother was silent for a while and soon asked again.

He Ku shook his head and said, "I haven't been in the military compound. I have been living in the countryside, and my great-grandfather and others have been in the countryside."

"That must be! He Shanlin must be your great master!" After hearing this, Grandma Nie Xiaoya said something inexplicable.
