There was no sophisticated chip technology in the 1980s, and there were very few microcontrollers. Most circuit functions were controlled by electronic components such as resistors, capacitors, and diodes.

"FM 106.1 MHz, this is a radio station..."

"Brother Hao, it's done. Look, you can receive the sound."

Qiao Erqiang happily put down the Luo Tie in his hand and happily showed the fruits of his labor to Qin Hao.

Qin Hao gave him a thumbs up: "Not bad."

"However, the sound is still a bit noisy. Use a multimeter to measure the voltage of the inductor. If there is no problem, then you can basically judge that the speaker needs to be replaced..."

After listening to Qin Hao's instructions, Qiao Erqiang nodded repeatedly, and then continued to repair the radio that he had dismantled beyond recognition with great enthusiasm.

Seeing this, Qiao Yicheng shook his head secretly: "It would be great if he was so interested in learning."

"You, don't look down on electrical appliance repair. Maybe the second best in this field will be more successful than you in the future."

Qin Hao's words made Qiao Erqiang beam with joy. Compared to his serious and rigid elder brother, he was more convinced of Qin Hao's easy-going personality.

"You, just get used to him." Qiao Yicheng said in amusement.

Qin Hao and Qiao Erqiang just looked at each other and smiled, ignoring Qiao Yicheng's complaints. This has been the norm these years. Qiao Yicheng was a little tired and felt that it was getting harder and harder to take care of his younger siblings, although he also understood

As he grows older, his younger brothers and sisters will no longer follow him and call him "big brother" every day, but they will obey his instructions, but he still feels that as the eldest brother, he is responsible for their lives.

After Qiao Erqiang replaced the speaker and the radio's casing, he excitedly took it to present treasures to his friends.

"The top two are almost 12 years old this year. They will go to junior high school next year. They are no longer children. Don't always act like an old father and keep a straight face. Your father occasionally smiles at them." Qin Haoshan

He lazily spoke to Qiao Yicheng.

When Qiao Yicheng saw Qin Hao comparing him with his father, he said with a dark face.

"It doesn't matter to him anyway, I can't just watch them grow crooked."

Qin Hao said angrily: "Here we go again, Qiao Yicheng. Sometimes I wonder if there is an ancient person living in your mind. How can you come up with so many elder brothers and fathers' sense of responsibility?"

"Both of your parents are dead, so why do you need to think so hard about them? Do they have to grow up according to the trajectory you set to be successful? Don't think of yourself too great, you are just a ten-year-old

Just a six-year-old high school student."

Qiao Yicheng was speechless for a moment. Yes, he was just a high school student, but why did he feel that he had been an adult for a long time?

Two days later, Wei Shuying came to school to hold a parent-teacher meeting for Qiao Erqiang, and the head teacher called her to the office alone.

"Ms. Wei, Qiao Erqiang has made great progress in mathematics this semester, but his Chinese is still the same. As parents, you should try your best to guide him..."

Wei Shuying sighed. She was used to being criticized for holding parent-teacher meetings for her second son.

"There is another thing that I want to tell you. Recently, some students in our class lost items. Some people said that Qiao Erqiang stole it. Moreover, I also found that Qiao Erqiang was wearing some strange clothes. The price of these things is not cheap.

, one piece costs more than ten yuan.”

Looking at the striped T-shirt in front of her, Wei Shuying's eyes widened: "Teacher, do you suspect our second strongest family member of stealing something?"

"Ms. Wei, don't get me wrong. I'm just suspicious now. As a parent, I think you need to have a good talk with your child."

"Okay, teacher, don't worry, I will definitely investigate this matter clearly."

Wei Shuying just came out of the class teacher's office and was about to go back to the factory to work. She happened to bump into Qin Hao. They were just chatting for a few words. After Wei Shuying left, Qin Hao's expression changed drastically and he pulled up Qiao who was getting ready to go to class.

10% rushed home.

"No, what are you doing? There is still one class before school is over." Qiao Yicheng was very puzzled by Qin Hao's behavior.

Qin Hao didn't bother to explain, and pulled Qiao Yicheng and ran all the way. Just now Wei Shuying said that she was here to hold a parent-teacher meeting for Qiao Erqiang. According to the time, the incident with Sanli should have happened today. At this time, she should return
