In the evening, Chen Yuzhu came to the outside of the compound and explained the reason. The comrade standing guard at the post called Zhong Yuxiu to inform her. After receiving a satisfactory reply, he told Chen Yuzhu.

"Student Chen, come here and register. I'll take you in." The comrade on duty at the guard post was a young comrade, in his early twenties, younger than Chen Yuzhu. He acted strictly according to the rules and did not make any mistakes.

"Okay, thank you, comrade."

Chen Yuzhu walked into the guardhouse. The soldier on duty handed him a large, wide booklet, opened it to a half-written page, and handed him a pen. "Fill in the blanks below."

"Okay." Chen Yuzhu nodded in agreement and quickly wrote down his name, identity information, and the purpose of his visit to the compound. "Comrade, I've filled it out."

The soldier comrade took a look and nodded, "Okay, follow me."

As the soldier comrade walked out of the guard post, a man wearing the same military uniform as the soldier comrade came forward; the two exchanged glances, saluted each other, and passed each other.

Chen Yuzhu suddenly realized. He was just thinking that there was no one guarding the booth, and immediately someone came to take over.

The soldier led the people to the small building belonging to Zhong Yuxiu. Seeing the door was wide open, the soldier walked to the door and shouted, "Report."

"Come in." A deep male voice came, and the soldier's comrade asked him to come in. Before he even reached the hall, Yan Rushan came out to greet him. "Comrade Zhong, thank you for your hard work. Leave the person to me."

"Okay, Comrade Yan, I'll go first." The soldier saluted and left.

As the man left, Yan Rushan set his eyes on Chen Yuzhu. Today, Chen Yuzhu was wearing a Zhongshan suit that had been washed to a pale color. He stood tall and straight, and looked in good spirits.

"Student Chen, come here, the professor has been waiting for you for a while."

"Yes." Chen Yuzhu followed and walked into the hall, and the first thing he saw was Zhong Yuxiu sitting on the sofa reading a book.

"Yuxiu, I've brought the person to you." Yan Rushan said. Zhong Yuxiu looked up, her eyes fell on Chen Yuzhu's face, and she smiled and said, "Student Chen is here. Did you have a smooth journey?"

Chen Yuzhu smiled back, "Hello, Professor Zhong. The journey was smooth. Thank you for your concern."

Zhong Yuxiu nodded in satisfaction, and said inconspicuously, "Once you enter the compound, you can't wander around. Come directly to me next time."

"I've made a note of it, don't worry."

"I'll have Comrade Yan take you to get an ID card later. This will make it easier for you to enter and exit the compound. Also, I have to remind you to let me know immediately if anything happens in class. If any classmates have academic problems, please write them down in a notebook. If you think they're enough and worth the trip, come and see me. I won't say much else. Just be moderate in your actions."

She did not always keep an eye on the students in the class. In a sense, the students in the class were left to their own devices. After she had won over the students, she did not manage them much. The class leaders did their job well, and no problems arose after a year. Therefore, her management direction was correct.

"While I'm away from school, the class leaders will have to work harder. When you go back, tell them that this is the time for them to demonstrate their abilities. During my year away from school, how much you class leaders can grow depends on your own abilities."

She has already given her maximum authority. Anyone who is capable can assist Chen Yuzhu in carrying out his work; if they are capable, they can also suppress Chen Yuzhu and stand at the top.

As long as the competition among classmates is healthy, she never interferes.

"yes."

Chen Yuzhu nodded in agreement, and he understood better. Zhong Yuxiu's words to him were also meant to remind him. "Professor, next week is our physics department's midterm exam. I have a collection of questions I collected from my classmates. Could you take a look at it?"

"Give it to me." Zhong Yuxiu nodded. Chen Yuzhu pulled out a palm-sized booklet from his pocket. The booklet was thick, estimated to be about one centimeter thick. Zhong Yuxiu took it and flipped through it carefully. Then she said to Yan Rushan, "Bring me some paper and pen."

"Okay." Yan Rushan went to the utility room to get paper and pen. The paper was the large double-page white paper she used for painting.

Zhong Yuxiu wrote down the solutions to the problems recorded in the booklet one by one on a piece of white paper; groups of numbers appeared on the white paper. These numbers were not the answers, but were used as guidance.

After the guiding ideas came out, she continued to write down the specific problem-solving ideas on another piece of white paper; she wrote down as many as there were, and combined them with the previous problem-solving guidance. As long as she studied it carefully, it was not difficult to understand.

"I've listed the guiding ideas and answers for the problems. Take them home and study them thoroughly. Then, discuss them with your classmates. I've listed several different ways to solve the problems, but the final answers are all the same."

Looking at the two large white papers filled with formulas, Chen Yuzhu's glasses lit up. He took the papers with both hands, folded them, and put them close to his body like a treasure. His eyes were full of admiration and respect as he looked at Zhong Yuxiu.

"Professor, you are amazing. Not only can you solve problems, but you can also solve them in a variety of ways."

"Study hard and you'll be able to do it in the future. When you have free time, you can collect some exercises and have your classmates try them out." Zhong Yuxiu shared her experience studying in the Interstellar Era. "You must know that no matter how good your academic performance is, practicing exercises is the best way to go. The more you practice, the more you'll gain experience, problem-solving skills, and problem-solving methods. Only when you have a clear plan can you be fearless on the road ahead."

The last sentence is a reminder to him.

When people are confident and confident, they will never feel guilty or timid; only those who lack confidence and self-confidence will be timid.

Chen Yuzhu nodded solemnly, "Professor, I have noted down everything you said. I hope that one day I can be like you." No matter what kind of difficult problem he encounters, he can solve it easily and even use multiple formulas to solve it.

It is always better to set a goal than to be ignorant about what to learn.

After seeing Chen Yuzhu off, Zhong Yuxiu had some free time again. Her hands were itching to do experiments after not doing any experiments for many days. However, Yan Rushan refused to let her into the laboratory. In desperation, she had to put aside her thoughts of doing experiments and asked Yan Rushan to get some more white paper.

Since I can't do experiments, I'll just do some physics questions. A group of outstanding students selected by the Physics Department will need them. If I write a little bit every day, I should have accumulated quite a lot by the time Chen Yuzhu comes next time.

There is one more thing to do, so if you are bored, just write a few questions; then give the solution ideas and answers together.

However, the next day, the meat sauce that Yan Ruhai wanted was made. It contained beef, mutton, pork, and chicken, all meaty things. Zhong Yuxiu felt upset when she saw that they were inedible.

"Sister-in-law, thank you and Goudan. I've taken the meat sauce. Since you can't eat meat now, I didn't save any for you. There are four jars in the kitchen, which are for my brother, grandfather, elder brother Haonan, and elder brother Tian Shangguo."

He took away more than a dozen cans and a large bag of steamed buns.

Zhong Yuxiu was even more upset. Everyone else in the family could eat the food, but she could only eat the leaves, which made her feel sad.
