Lin Shengli is about to regain his legal status, so he can now teach his children openly and legitimately.

Knowing that Lin Yi was interested in mechanical physics, he promised to bring him some really good books.

Of course, Lin Yi didn't know that the book his father mentioned as exceptionally good was one that was personally tailored for him.

He was already very happy to hear that Lin Shengli had agreed to bring the books.

The family chatted on the phone for quite a while, until Aunt Wang reminded them about the phone bill, at which point they quickly hung up.

Both sides have to pay for the call, so Lin Shengli ended up having to pay several yuan as well.

But the money was well spent; the old man was so happy that he hummed a song on his way home.

It's the Lunar New Year, after all, so it's good to make him happy.

Shen He had a very happy New Year.

Although he can no longer keep in touch with many old friends, his daughter and son-in-law take him out shopping.

Go to the park to watch others play, and play chess with other old men.

Old Man Shen felt the joy of being alive for the first time in a long time, which made him feel that he could live for another 20 years.

Of course, Lin Shengli and Shen Zhinian should return to the research institute after the New Year.

"Dad, we both work in Beicheng, but we don't have many opportunities to come out. We'll come to see you whenever we have time."

Worried that the old man would be upset, Lin Shengli tried his best to comfort him.

Shen He waved his hand: "I understand. It's all for work. You are still young and should work harder."

Of course he knew that no one could be with their parents every day.

Shim Chinen also has her own little family, her own children, and a job.

Although he was very reluctant to part with her, he still expressed his understanding.

Knowing that his daughter is still alive and well, and being able to spend this time with her, Shen He is already very content.

The two arrived without warning and left quietly.

It wasn't until the next day, when the neighbors didn't see Old Man Shen's son-in-law come out to hang up the clothes, that they realized they had already left.

Worried that Old Man Shen would be upset, the neighbors went to his house to visit him.

Shen He smiled and said, "I'm fine. It's not like the child will just leave and never come back."

The neighbors noticed it as soon as they arrived at his house.

Old Shen's house has changed dramatically.

The old furniture was repaired and cleaned, and there was still plenty of food stored in the kitchen.

One can imagine how meticulous and considerate the person who arranged all this for him must have been.

The neighbors all said enviously, "You really have a good daughter."

Shen He felt proud: "Yes, my daughter is a filial and good child."

Knowing that his daughter still cared for him as her father, he wasn't too sad when they left.

There will always be another chance to meet.

......

The Lotus Brigade has already finished celebrating the New Year, and the food factory has resumed operations.

With all the workers present, the work resumed in full swing.

Some orders were placed before the Lunar New Year, and we have to rush to complete them now.

“My parents called last time and said our products are selling very well in Beicheng. I think this market is still huge. Who among you would like to go with Comrade Zhou Huanan to explore it?”

The current sales staff are Zhou Huanan, Li Dahui, and Lin Yuan.

Zhou Huanan was responsible for orders in the northern part of the city, while Li Dahui and Lin Yuan were responsible for orders in the surrounding provinces.

This time, Lin Yu wanted one of them to go with Zhou Huanan to expand the market in the north of the city.

Both Lin Yuan and Li Dahui wanted to go, and after discussing it, they decided that Lin Yuan would go first this time.

"Oh dear, Uncle Dahui's child is still young, let's go next time."

The child is still at a stage where she can't let go of him, so Ms. Ou has gone home to be with Mr. Ou.

Li Dahui needs to take better care of the children.

Lin Yu nodded: "Okay, then it'll be just the two of you going this time."

It would be best if Lin Yuan went; Lin Yu also wanted to ask him to bring something to her grandfather.

My parents have already called to say they won't be able to come back anytime soon.

Gu Yunze revealed some details, saying that her parents are both important scientific researchers.

Lin Yu then knew that they must have gone to a classified unit.

Therefore, she gave up contacting them and could only wait for them to call her on their own initiative.

Then she remembered that she had a maternal grandfather in Beicheng, and her parents didn't have time to take care of him. To show her filial piety, she thought of asking Lin Yuan to bring some things over.

Grandma Lin wholeheartedly agreed: "Your mother has been married into this family for so many years and has never been home. It's right for you to be more filial to your grandfather on her behalf."

Grandma Lin was also very curious about this in-law she had never met before.

I chatted with him on the phone for a bit last time, and I got the impression that he was a cultured person.

There were many things that Chen Zhinian couldn't easily explain over the phone, so they weren't very clear about them.

But now that Lin Yu and Lin Yi know they have this relative, they have to keep in touch.

Grandma Lin prepared a lot of things, including cured meat she made herself, and several pieces of clothing made from the fabric Lin Yu brought back.

Lin Yu prepared some products from the food factory, wrote a letter, and asked Lin Yu to take money to her grandfather.

Lin Yi knew that his sister wanted to bring something to their grandfather, so he racked his brains to think of something to give to their grandfather.

Lin Yu knew he'd been tinkering with something lately, and remembering the loudspeaker, she asked, "What are you going to do with it?"

Lin Yi said, "The radio."

To be precise, he wanted to make a crystal radio.

Lin Yi asked Lin Yu to help him buy ore, coils, and variable capacitors from the department store in the county town.

You will also need an earphone.

Lin Yu, eager to see his finished product as soon as possible, immediately ran to the county town to buy it for him.

Lin Yi saved all the money himself.

A single ore costs a little over 10 cents, an electric coil costs 54 cents, and a variable capacitor costs two yuan.

The most expensive item was the headphones, which cost five yuan.

He made the radio casing himself out of wood, and when he finally assembled it, it didn't look like a radio at all.

It's a bit rudimentary.

All the kids in the family were squatting there watching, just wondering if it would work.

Lin Yi remained calm and composed. He connected the radio's wires and turned the handle.

"The loudspeaker is broadcasting!"

A sound came from inside.

Tie Dan shouted, "It's a success!"

Lin Yi nodded: "Yes, it can be used."

Lin Yu was even more surprised; it turned out that it was actually possible to make a radio by oneself.

As a liberal arts student, she really didn't understand these things.

But Lin Yi is just too amazing!

Gu Yunze looked at Lin Yi with sparkling eyes, thinking that this child was a talented person.

The children were overjoyed: "We have a radio to listen to now!"

Then he listened intently to the short stories on the radio, completely absorbed in them.

Lin Yi, on the contrary, did not seem so excited.

Lin Yu asked him, "Are you happy?"

Lin Yi nodded: "I'm happy, but I made it myself. I know the principle behind it isn't difficult, so it's nothing special."

After listening, Gu Yunze patted him on the shoulder: "You did a great job."

At such a young age, he remains calm in the face of both praise and criticism, and is very confident in himself. He will surely achieve great things in the future.

When Lin Aiguo and the others returned home, they were overjoyed to hear that Lin Yi had actually assembled the radio himself, and they couldn't wait to announce it to the world.
