What to do after the exam is still what to do.

Mu Jingchi and Zhang Chuyang are still in the stage of continuing to study, especially for direct doctoral students, there are many and miscellaneous things to learn. After all, materials science is an interdisciplinary discipline, and you must know a little bit of everything, and sometimes even be more proficient in everything.

For the time being, the first semester of this doctoral year will be spent in the process of studying. Wait until the second semester of the Ph.D. to take the qualification exam, and after the qualifying exam, you will have to give a topic selection report and start your formal doctoral life.

Of course, before that, you still have to choose a good research direction.

Huaqing University's materials discipline ranks first in the country and ninth in the world, which is very strong. The study of materials under extreme conditions is only one of the general directions, and there are many smaller directions below this.

For example, the calculation of mechanical parameters of materials under high temperature and high pressure, the study of the physical properties of intermetallic compounds in alloys under extreme conditions, the first-principles study of the structural phase transformation and physical properties of materials with different crystal systems, etc.

There are many research directions that can be chosen, and as direct doctoral students, they can only start from a simple one, and then become stronger and stronger, and then they can do big projects.

Professor Yang did not send the test papers back soon after receiving them, and Mu Jingchi was not in a hurry, he continued to accumulate more knowledge of materials science, especially in the theoretical direction.

Although materials science is an experimental discipline, with the development of materials science and engineering, theory has become increasingly important. The research and development of new materials must have sufficient theoretical support and be carried out under the guidance of theory.

It's just that the current material theory is not sufficient, and it cannot be quantitatively guided in production.

Evening.

After a day of graduate study, Mu Jingchi drove back to the city of Shengjing.

When he walked out of the elevator, he saw his mother Mu Huaiyun. My mother was at the door of the house, didn't go in, and was chatting with Aunt Zhao of the neighborhood with her bag.

After meeting every morning, Mu Jingchi already knew something about his neighbor.

Aunt Zhao is not from the capital, but from the south, because her daughter is studying in the capital, so she bought this house in Shengjing Charm City.

It also highlights that there is a mine at home, as for the daughter that Aunt Zhao said, Mu Jingchi has never seen it. It is said that he and his classmates went on a trip together during the summer vacation and have not yet returned.

After all, not all universities start as early as Huaqing and Yan University, and it is normal for students to start school in early September.

"Mom, why don't you go in?"

Mu Jingchi greeted Aunt Zhao, turned his head and opened the door.

"I'll talk about it when I have time in the future, so I'll go with Xiao Mu. Lao Mu greeted Aunt Zhao, and then followed Mu Jingchi in, "This is your own house! Although I am your mother, I will not disturb your space and invade your privacy." ”

Lao Mu has a lot of respect for Mu Jingchi and does a good job in details.

It is precisely because of these details that Lao Mu can start his own business, and the real estate company is thriving.

"There's no privacy, you can come in when you come over. Mu Jingchi said and casually put the keychain into the storage box hanging on the shoe cabinet in the entrance, "You know the password." ”

The door can be opened with a key or with an electronic code. Mu Jingchi published the password in the WeChat group of 'Blind Date and Love Family', and everyone knows it.

Lao Mu nodded, but his eyes were wandering in the living room, dining room, and kitchen.

Unlike the situation that may be bad as imagined, the whole room is clean and tidy, and Lao Mu deliberately wiped it on the cabinet with his hand, but there was no dust.

The general layout of the house has not changed, some small decorations have been adjusted, and a few other things have been added.

There is an extra bookshelf next to the sofa in the living room, on which there are not professional books on materials, but some novels at home and abroad, which should be used to pass the time for rest.

And on the balcony of the living room, there are a few more touches of green, which is very amazing to see Lao Mu.

There are rows of potted plants, cactus, aloe vera, succulents, pothos, spider plants, bamboo, ivy, although they are all small pieces placed on the balcony, but they look full of life.

"I didn't find out that you like to raise this kind of bonsai before, but it is good to live by yourself, and you can live according to your own ideas. Lao Mu walked over and gently dipped his hand on the branches and leaves, and suddenly felt a burst of clear breath.

"Why don't you have another pet? You're so lonely. ”

Seeing that there were no mosquitoes flying on these potted plants, Lao Mu also temporarily put his mind at ease, with a smile on his face, and put forward his own suggestions.

"Tea or coffee?" Mu Jingchi didn't understand what he said, and turned to his mother to ask rhetorically.

"Coffee. ”

Lao Ji drinks tea, and the teacup does not leave his body, but Lao Mu likes to drink coffee.

Mu Jingchi used the kettle of hot water, poured out the coffee beans, and began to grind by hand, "There is no need to raise pets for the time being, I now go out every morning and come back at night, I don't have time to accompany my pet, and my pet's food can't be solved." ”

Whether it's a potted plant or a pet, Mu Jingchi likes it very much. And now that there is a system that can help, the conditions are more suitable for him.

It's just that Mujingchi itself has time and energy problems, the potted plants are fine, and the pets really have no choice but to drag them back.

The old mother sat on the sofa in the living room, asked Mu Jingchi to sit down as well, glanced at the action of grinding coffee beans, and then said: "Xiao Mu, you are now 22 years old, you have a lot of houses and cars, and you are still a doctor." ”

"Do you have any thoughts on your personal emotional problems?"

Lao Mu didn't come here today for this matter, she wanted to come over to see how her son was doing, whether it would have made a mess of the house.

The fact is that it is very different from what she thinks, her son lives very well, looks exquisite and tasteful, and still looks indifferent.

But talking to the neighbor's sister outside the door before suddenly gave her a sense of crisis.

You know, until now, his son has not been in love, and he doesn't seem to have the idea of falling in love, even those goddesses with good knowledge and appearance in Huaqing University have not moved him.

Thinking of the impression of his unfortunate marriage to his son when he was young, Mu Huaiyun felt a little apprehensive in his heart, "Could it be that my own experience made my son resist marriage and distrust love?"

Otherwise, why didn't his son fall in love with such an excellent son?

So, Lao Mu couldn't care so much and began to test Mu Jingchi.

Mu Jingchi's hand froze suddenly, and then continued to grind coffee, "I didn't meet a suitable one." ”
