Verification

That's how it is in college; if you want to enrich yourself, you'll be busy as a dog.

If you want to indulge yourself, you'll just be bored out of your mind.

No one will take the initiative to manage you; it all depends on your self-discipline.

From the perspective of social development trends, it's always best to learn more knowledge. People shouldn't learn new skills after thirty; one should start studying while young.

Although it is said that one should learn until old age, human energy, physical strength, and memory gradually decline with age. With national affairs, family affairs, and world affairs to worry about, not many uncles and grandfathers can truly settle down and continuously enrich themselves.

Professor Sun Erxiong of the School of Mathematics was a top student in college, but now that he's over fifty, he can't seem to learn anything anymore and is just relying on his past achievements.

Academic research and teaching are Sun Erxiong's main jobs, taking up more than half of his time.

His daughter, Professor Sun, is twenty-five or twenty-six years old and has inherited her father's plump figure. At 1.60 meters tall and weighing over 160 kilograms, she doesn't even have a boyfriend. How could her father, Professor Sun, not worry?

Sun Erxiong came from a rural area, and his relatives from his hometown would frequently ask Professor Sun from Yenching University for help.

The medical facilities in the capital are good. Erxiong, could you please get me a referral to a top-tier hospital? I need treatment for my diabetes.

The capital's educational resources are top-notch, Erxiong! Get your nephew into a prestigious middle school; knowledge changes destiny. What? You can't arrange it? You, a professor at Yan University, can't even handle such a small matter?

Sister, I'll take care of my nephew's schooling. Don't worry about it, I'll handle it. He has to get into the best middle school in the capital.

It's not something Sun Erxiong can do with just a few words to get a child from out of town to attend a top middle school in the capital. He's a mathematics professor at Yenching University, not the Minister of Ministry of Education.

Even if it's difficult to operate, it still has to be done. Sun Erxiong is busy with these little things all day long. It's too difficult for him to learn until he's old. He can't calm down.

"Smoke less, Professor Sun," Shen Qi advised in Sun Erxiong's office.

"Shen Qi, my only hobbies are smoking and drinking tea. You'll understand when you're my age." Sun Erxiong stubbed out 0.5 Zhongnanhai cigarette between his fingers and sighed, "There's nothing wrong with marrying science, really. If I could be reborn, I'd definitely do it. Why bother with a wife? It's so annoying!"

"Did you say the same thing to your teacher's wife?"

"Of course!" Sun Erxiong's body stiffened, and he gave a wry smile, "Of course I can't tell my wife, she doesn't understand the world of mathematicians."

"Shen Qi, you're so handsome, and you excel in all aspects of life. Do you have a girlfriend?" Sun Erxiong asked seemingly casually.

Shen Qi said, "Professor Sun is absolutely right. There's nothing wrong with marrying science. Why bother with a wife at all? It's so annoying!"

"Shen Qi, you're the only son in your Shen Family, right? If you don't get married and have children to carry on the family line, will your parents agree? As for girlfriends, you can date whoever you want; when fate brings you together, you can't stop it. Back in the day, I was just as handsome as you, and I excelled academically. Among a bunch of beautiful girls, I chose my wife, who wasn't particularly pretty. There's nothing I can do about it; that's just fate."

"Professor Sun, can I admire your photo from when you were young?"

"We didn't have cell phones back then, and taking pictures wasn't common," Sun Erxiong said with a regretful expression. "By the way, what brings you here?"

Shen Qi took a document from his bag; it was a printed copy of a paper titled "Analysis of Generalized Nonlinear Complementarity Problems with Linear Inequality Constraints." He said, "Professor Sun, could you please review this paper for me?"

Today is the fourth day after the Marxist Philosophy exam, Shen Qi has completed his last and most difficult paper.

Of the first four articles, Shen Qi submitted them to three different journal editorial departments.

The paper co-authored by Ou Ye and Shen Qi was submitted by Ou Ye to a core domestic journal.

Shen Qi felt there were no major problems with the first four articles; he approved them himself and they were fine.

For this last piece, Shen Qi was 90% confident. He needed Sun Erxiong's advice and suggestions for the remaining 10%. After all, Professor Sun had been researching on the front lines of mathematics for many years and was very experienced.

Sun Erxiong took the paper and flipped through it, then asked, "It seems like it was a little over a month ago, I asked you to transform 5 out of 36 Advanced Algebra problems into 5 papers. How many did you transform?"

"The one Professor Sun is holding is the last one," Shen Qi replied.

"You wrote five papers in just over a month?" Sun Erxiong was very surprised. He reminded him, "Shen Qi, don't just write whatever comes to mind to reach the word count. Even if you submit to a general journal, there will be a review process by industry experts. The experts' level is no worse than mine. After the expert review, there is also the editorial board's final review."

"There are rumors in society that the academic atmosphere in China is not healthy, and I won't comment on that. But I can tell you with certainty, Shen Qi, that among all academic disciplines, mathematics has the most upright atmosphere, with the fewest instances of academic corruption and fraud. So don't think that you can just write a paper and submit it and expect it to pass review easily."

"You can't fake mathematics. This discipline doesn't rely on equipment or experimental data; it's all about imagination. Professor Sun, I really didn't write this paper carelessly. Would I ruin my reputation? Am I stupid?" Shen Qi said. "Let's stick to the facts. Take a look at this paper first."

Sun Erxiong quickly skimmed through <Analysis of Generalized Nonlinear Complementarity Problems with Linear Inequality Constraints>, somewhat surprised. "It's written in such a complex way; let me review it carefully for a few days."

Shen Qi asked, "How many days? Can it be done before 5 o'clock tomorrow? I'm in a hurry, Professor Sun. It's already early December. If it's not submitted before December 10th, we definitely won't get a reply until after the New Year. The editorial departments of those core journals don't start work until after the Lantern Festival. If this is delayed, it will be delayed until March next year!"

"Hey, you're the student, I'm the teacher. You're asking me for a favor, and you're acting so arrogant? Don't you know what it means to respect your teacher? Shen Qi, go back now and do what you need to do. I'll give you my review recommendations in two days. Do you know how busy I am? I have a ton of problems at home, and I'm completely overwhelmed." Sun Erxiong waved his hand, dismissing Shen Qi.

After Shen Qi left, Sun Erxiong closed and locked the office door. He brewed Maojian tea, lit a Zhongnanhai, and carefully studied Shen Qi's paper.

The aroma of tea wafted through the air, and the smoke curled upwards.

This year's Maojian tea, paired with this year's 0.5 Zhongnanhai, is a favorite among Old Yan.

The best part would be some orchid beans!

There are some orchid beans from this year's harvest in the office.

It's a broad bean, not a peanut. Those peanuts are too delicate and can't support Sun Erxiong's weight of over 200 pounds.

The tea is good tea.

The beans are good beans.

The smoke may be bland, but it has a unique flavor.

This year's tea, this year's beans, this year's cigarettes—these are Sun Erxiong's few little hobbies.

Men, no matter how tough, tiring, or wronged they feel, they have to learn to take good care of themselves.

Sipping tea, smoking a cigarette, and cracking open beans, Sun Erxiong reviewed the paper in front of him—a mathematics paper produced this year.

After a long while, Sun Erxiong slapped his thigh in exhilaration. "Wonderful, wonderful!"

"But why is this matrix positive semi-definite?" Sun Erxiong suddenly noticed a suspicious point.

"I need to double-check. I can't let Shen Qi fool me. His specialty is complicating simple problems."

Sun Erxiong stubbed out his cigarette, poured himself some tea, and finished the remaining orchid beans.

He picked up his pen and focused intently on verifying part of the derivation process in Shen Qi's paper.
