Xia Zhaoning was admitted to the mechanical engineering major of Tsinghua University at the age of eighteen.

Since she moved to Beijing, she often went to classes with Xia Weian.

Xia Weian chose mechanical engineering as her major. Although the girl was young, she listened with great interest to some professional terms that she didn't quite understand.

When Xia Weian started to practice, the little girl followed him and served as his assistant.

Although the little girl is young, she is really good at hands-on work.

Xia Zhaoning can always perceive what Xia Weian needs at the first moment and deliver it to him accurately.

When Xia Weian was in his senior year, the father and daughter successfully built a simple engine by hand. Although the technology was not as good as that of developed countries, the fact that the two of them could do it by hand shocked the whole school.

Later, with the cooperation of other team members, the two people's engine technology was developed to a deeper level, and Xia Zhaoning also learned a lot of knowledge.

Because she and Xia Weian have similar interests, Xia Weian likes to take Xia Zhaoning with him wherever he goes in recent years.

The two of them are like ordinary father and daughter, and they often slam the table at each other when discussing professional knowledge.

In Xia Weian's words, at this time we are not father and daughter, we are comrades who discuss and make progress together.

After graduating, Xia Weian went to work in a machinery factory in Beijing, so Xia Zhaoning had more places to play.

She would take the initiative to ask Xia Weian to work overtime every weekend, and she would accompany him. During the winter and summer vacations, she would run to Xia Weian's factory after finishing her homework.

At first, engineers who didn't know Xia Zhaoning thought Xia Weian was too indulgent with his child and thought bringing a child to work would add a lot of burden to them.

Later, Xia Zhaoning helped them solve practical problems time and time again, and everyone realized that this little girl was really smart.

Over the years, the family has been equipped with more and more practical household appliances, including electric fans, washing machines, refrigerators, and even televisions, all made by these two.

Xia Zhaoning had already registered at the machinery factory early on.

The director of the machinery factory said to Xia Weian earnestly, "Weian, this position of mine is yours."

"When Zhao Ning graduates, whether you want to retain talent for yourself or find a right-hand man for yourself, you must recruit her to our machinery factory. She is our hope for the future."

Xia Weian, "I'm also quite young, I also hope..."

The factory manager said, "You are already in my hands. What I want is not here yet. Don't let another factory take you away."

The country has been developing better and better in recent years, and Shanghai and some coastal cities have been developing slowly.

They do not hesitate when recruiting people and pay them generously, especially for professionals like Xia Zhaoning.

The factory manager felt that he had to act early, and only after receiving Xia Weian's assurance did he feel relieved.

At this time, there was a craze for studying abroad. After Xia Zhaoning had studied at Tsinghua University for two years and was in her junior year, she took the initiative to ask to go to Country D as an exchange student.

The year Xia Zhaoning decided to go to Country D, she was only 20 years old. Her family was definitely worried about her going abroad alone.

Song Qingyun couldn't sleep well for several nights in a row, and Xia Weian kept comforting her.

"When children grow up, they will go out sooner or later."

They know that Country D is relatively safe now.

In addition, Country D's industrial development is indeed good, and some of its technologies, especially in the automobile manufacturing industry, are far ahead of their domestic counterparts.

After Xia Zhaoning goes there to study, he will definitely bring back some new technologies, and maybe even research some new materials.

Xia Weian supports Xia Zhaoning intellectually, but as an old father, he is also worried about Xia Zhaoning going abroad alone.

Originally, Xia Weian thought that after Xia Zhaoning went to college, he should also find a partner.

The best one is from Tsinghua University, with the same major, so that the two of you can develop together in the future.

At this moment, Xia Weian thought even more that if there was such a person to accompany Xia Zhaoning abroad, his family wouldn't have to worry so much.

So the old couple discussed it, and finally Song Qingyun asked Xia Zhaoning.

"Is there any boy in the class that you feel you get along with better?"

Xia Zhaoning: "If you ask me which male classmate has stronger professional knowledge, I know. If you ask me who I get along with the most harmoniously, we all get along well."

Because when they are together, they never talk about anything other than their studies.

Xia Zhaoning is pretty and a rare girl majoring in science and engineering. She attracted the attention of many boys at the beginning of the school year.

It is the wish of many people to have a sweet love in college, but no matter who Xia Zhaoning faces, he always has an attitude of "I want to study hard, and you have to study hard too."

Some people came to discuss life ideals and romantic matters with her, but Xia Zhaoning talked about everything from her profession to her dreams and the future of the motherland.

Along the way, everyone knew that Xia Zhaoning's ideals and beliefs were quite firm, and ordinary people like them really couldn't impress her.

So Xia Zhaoning remained single despite studying mechanical engineering, a major with many boys.

When Song Qingyun asked her, Xia Zhaoning's expression was indescribable.

She didn't know why her mother thought she needed a boyfriend?

When I was in college, it was either because the lectures were not interesting enough or the experiments were not fun enough.

What's a man? He'll only hinder her efforts in studying!

Song Qingyun: I am superficial.

In the end, Xia Zhaoning went to Country D with his classmates.

Before leaving, Xia Suihe gave Xia Zhaoning all the simple and easy-to-carry medicinal powders she could make.

He also brought her some specially made medicines for various conditions, such as colds, fevers, allergies, acclimatization, diarrhea, and hemostasis. In short, Xia Suihe brought her all the medicines he could think of.

This time Xia Zhaoning is going abroad to study, and she won't be back in one or two months. She may be away for two or three years.

The family felt very heavy-hearted when they thought about not seeing Xia Zhaoning for so long.

Xia Zhaoning was the most relaxed. She hugged Song Qingyun and Xia Weian, and also hugged her eldest sister, second sister, Xia Qingyu, Xia Changle, Xia Zhihuan and Xia Suihe.

Xia Zhaoning told them not to worry, and that he would take good care of himself even in Country D.

The children in their family are all very self-reliant and can do everything by themselves, including washing clothes and cooking.

Xia Zhaoning felt that she was going there to study, and that she could learn better technology in a more advanced country. She felt that such days would be extremely beautiful.

"Dad, don't worry, I will definitely learn their advanced technology."

"Okay, Dad will wait for you at the machinery factory." Xia Weian's old father felt very sad.

The family said goodbye and sent Xia Zhaoning on the plane...
