At eight o'clock the next night, it was already dinner time. Li Xiaodun walked into the building unit of Professor Wei and Mrs. Liu with a cardboard box in one hand.

One box contains snake fruit and the other box is banana.

When buying expensive gifts, Li Xiaodun was afraid of scaring Lao Weitou and Lao Madam Liu. Instead, he destroyed his beautiful image in the minds of the elderly.

And this is as good as visiting each other every day. At worst, you can go and buy more times.

After the door opened, the kind and kind face of Mrs. Liu was revealed.

"Oh, it's you, the young man!" Old Mrs. Liu said in surprise. She also reached out and patted Li Xiaodun's chest twice.

Five white fingerprints were left on Li Xiaodun's chest.

"I'm just cooking, I forgot to wipe my hands. I'm sorry." Mrs. Liu said with a smile and then walked towards the kitchen to find a rag.

Li Xiaodun also walked in with two boxes of fruit in his arms.

"The two teachers are old and it's hard to buy things. I bought some fruits and brought them here." Li Xiaodun explained with a smile.

Li Xiaodun was a little nervous. This was his first time buying something for a teacher, although he was a retired teacher.

"Why buy things?" Old Mrs. Liu said with a little dissatisfaction.

"Professor Ban wants to write me a letter of recommendation. He told me that you have said a lot of good things to me in front of him. I feel sorry for it, so I just said," Li Xiaodun couldn't continue.

This is the first time he has been so utilitarian to buy something for others.

Looking at Li Xiaodun's flushing face and embarrassed look, Mrs. Liu's face calmed down.

"Wash your hands and make dumplings with me." Mrs. Liu said.

"Why haven't you eaten so late?" Li Xiaodun asked curiously.

"The supper is ready, but the old man in our family must eat dumplings!" Mrs. Liu replied angrily.

Li Xiaodun suddenly felt inexplicably moved. Her husband was sick, and his wife took care of her husband like a child. If this was not love, what was love?

After washing his hands, Li Xiaodun walked into the room. Professor Wei was already sitting next to the table and was ready to go.

"I'll roll the dough, you'll make dumplings." Old Mrs. Liu said as she started to do it.

Li Xiaodun picked up the dumpling skin and started making dumplings. Every time he made a dumpling, he put it down, Professor Wei couldn't wait to pick it up and put it on the curtain seriously. That focused expression was like doing an experiment.

The more you wrap the dumplings, the more you get.

Professor Wei placed the dumplings in a straight line horizontally and vertically, just like attending the National Day ceremony.

Li Xiaodun suddenly said with a childlike heart: "Professor Wei, you have put the dumplings in a crooked manner."

"Is that so? Let me take a closer look!"

Professor Wei looked at each team of dumplings carefully like a rifle aiming.

Not to mention, he really found a few dumplings that were slightly off the line. He immediately put them seriously and then showed a satisfied smile on his face.

"Don't tease him. Although his mind is not as good as before, he has not lost his seriousness at all." Old Mrs. Liu said with a smile.

Next, Mrs. Liu and Li Xiaodun talked about learning the above things.

Mrs. Liu used to be a teacher who taught advanced mathematics in school.

There are more teachers teaching basic courses in college than teachers teaching professional courses. And they are basically unknown.

Teachers in professional courses also conduct research and publish papers and projects, and can often gain both fame and fortune.

But without basic courses, how can you learn professional courses?

So from the perspective of obtaining, teachers who teach basic courses seem to suffer a little.

Li Xiaodun's enthusiasm for learning is a downward curve like most students, but the curvature is not too large.

He studied advanced mathematics in the first year of college, which is not bad.

But when I learn linear algebra, I'm just sloppy.

"I have a headache when I see matrix calculation!" Li Xiaodun said with a bitter look on his face.

"There is no unimportant knowledge. If you want to study computers in depth, matrix computing is indispensable. It is still not enough enthusiasm for learning. For example, the small class who wanted to write a letter of recommendation to you have a much higher enthusiasm for learning than you!" Mrs. Liu said with a smile.

Li Xiaodun was stunned. Unexpectedly, Mrs. Liu, who was in her seventies, still knew so well about computers.

"I learned the computer subjects very well. A classmate in my dormitory learned very well, and he was not bad compared to those in computer majors."

The person Li Xiaodun talked about was Yan Yufei.

"Although I don't study machinery, I also know that computers are increasingly inseparable from computers in the mechanical major." Mrs. Liu said.

When he heard the two of them talking about their academic affairs, Professor Wei raised his head and even forgot about dumplings. His originally dull eyes became alive.

Speaking of this, Mrs. Liu quickly talked about her son who had been proud of over the years.

The old lady started with the fact that her son could recite a few Tang poems when he was three or four years old.

I studied at one of the best universities in the country and learned from famous primary schools in the country until I received a full scholarship to study abroad.

Li Xiaodun accidentally turned around and saw the dull Professor Wei's face showing a bright look, and his eyes were also shining. Now it looks no different from normal people.

"Old Wei and I have basically collected and printed out the SCI papers he published over the years. Now there is a large thick book!" the old lady said with a smile.

"Finally, tenured professor!"

Professor Old Wei suddenly stammered.

"Oh, Lao Wei! Your head is finally working! Yes! Our son is a tenured professor at a world-renowned university!" Mrs. Liu said in surprise.

"When it comes to his son, his head is fine." Old Mrs. Liu said with a sigh.

Seeing his wife who was a little Alzheimer's disease suddenly shivered, tears burst out from her eyes.

"An ungrateful thing! I haven't come back for many years. I haven't come back from marriage, I just told you on the phone! If he brought our baby grandson back to see, maybe his father's illness would be better." The old lady said with a sob.

Li Xiaodun was also very moved. He couldn't answer the words at all.

The dumplings are made of leeks and eggs. This is for Lao Wei to eat. Mrs. Liu must keep Li Xiaodun for dinner. The two of them cleaned the meal they had made in the evening.

Although Li Xiaodun has had supper, he can still eat it!

"The family hasn't been so lively for a long time. You have to come often in the future! Don't buy anything anymore!" the old lady said with a smile.

"Eating more fruits is good for the body. You are old and it is too difficult to buy these things." Li Xiaodun replied.

"If there are any problems when going abroad, come to me! Our old man and I know many people! Don't be shameless!" the old lady instructed.

"It should be almost done." Li Xiaodun replied vaguely with a feast in his mouth.

He is now thick-skinned. He ate two-thirds of his entire meal tonight!
Chapter completed!
