On the same day, the editorial department of the Annals of Mathematics welcomed a special guest.

Han Sun.

Han Shan graduated from Fudan University, majoring in mathematics and economics, and after graduation, he stayed in the school as a counselor and served as a tutor for mathematics professional courses.

Obviously, Han Shan's arrival was not a surprise.

The two men in the editorial department recognized Han Shanlai.

"Mr. Han, are you coming to our editor-in-chief again?"

Han Shan nodded, "Well, I haven't been looking for him for a long time, I wonder if I'm there, is he there?" ”

"Yes, yes, right in the office."

"Then I'll go in and find him myself."

"Teacher Han, you are free."

Obviously, Han Shan is not the first time to come to this place, and he is also familiar with this place, and he soon stepped into the editor-in-chief's office.

"Han Shan, you kid really don't treat this place as an outsider, you just go in and out of this place?"

"Lao Xu, you are still the same, with your level, why do you want to nest in such a place, where is the development not good?"

Lao Xu's name is Xu Weiguang, and he and Han Shan are each other's college classmates and roommates, so the relationship is naturally good, and the other roommates either go to other cities to develop, or find another way out.

However, the two of them are in the same city, so there is usually more contact with them, and the relationship is naturally closer than that of other roommates.

When he has nothing to do, Han Shan likes to come to Xu Weiguang to catch up.

"You don't know my ambition yet, it's just so-so, just set up a branch in one place, and the salary is enough for me to support myself...... How to say, is it tea or a drink? ”

"Tea, isn't it boring to come to you without drinking tea...... You're not motivated, but you really don't have anything to say about enjoying life. ”

Xu Weiguang shook his head, "I knew that you were uneasy and kind when you came to me, and your feelings were purely for tea...... I don't know what kind of shit luck your kid has gone, someone just sent me a little Huangshan Maofeng last week, you are blessed, I'll go get some over. ”

Xu Weiguang got up and walked towards the bookcase in his office.

"Huangshan Maofeng? That's a good thing, it's worth several meals, hahaha, then my trip is not in vain......"

Han Shan's face burst into laughter, "By the way, Lao Xu, I said why haven't you found a girlfriend for so many years?" Look at you, you're in your thirties, why are you still in your thirties, and you don't have a proper ...... Anyway, Lao Xu, do you want a wife? If you want, I can introduce you to the resources of single women around me......"

Xu Weiguang said while making tea, "In these years, where is there any capital to ask for a wife, with my current salary of more than 10,000 yuan, I don't dare to buy a suite here, so I got a set in my hometown, with a monthly payment of about 6,000 per month, plus my car loan and usual expenses, this is just right, of course, there is a little surplus, but I can't save a few dollars a year, if I find a wife and have children, where can I still have the ability to take care of them?" Since I'm living fairly well on my own, there's no need to hurt others anymore, so as not to be ......talked about in the future."

Han Shan said, "Then are you going to stay in this kind of place for the rest of your life?" ”

Xu Weiguang said, "This is naturally not, there are still a few acres of land at home, if I really can't get along here, I can also go back to inherit my farmland, and plant some corn and sweet potatoes or something when the time comes...... I'm going to get to that point, don't forget my old classmate, buy me something back then. ”

Han Shan laughed, "Okay, it's okay to wrap you with an acre of corn, right?" ”

Xu Weiguang said with a smile, "This is what you said, so it's decided...... Let's talk about it, why do you have time to come to me today, you don't have anything to do but go to the Three Treasures Palace, you won't really do it for my stinky tea, right? ”

Han Shan said, "Sure enough, I can't hide anything from you...... Recently, I was troubled by a subject, and I studied it for a while, but I always had no clue, and it made people a little broken, you look at my hair, and now I grab a small handful every day, and I doubt that if I go down, it won't take long for me to be bald. ”

Xu Weiguang said, "You are bald...... What's the matter, and I'm bald? ”

Han Shan looked at Xu Weiguang, who was more empty than his head, and found some comfort in his heart.

"What subject? According to your ingenuity, there won't be a problem with this, right? Tell me what the subject is, and maybe I can help you a little. ”

"I've got a bit of a problem with the equation of linear constants, so I'm here to learn from you."

"Function Equation ......"

Xu Weiguang was stunned for a moment, and then spoke as if he had thought of something, "Han Shan, it just so happened that I received a letter some time ago, and it has passed the preliminary review, so it came to me, and I originally wanted to wait for someone else to review it when I was free, but since you are here, and you have troubles in this regard, then I can directly do something that kills two birds with one stone, on the one hand, I don't have to find someone to review the manuscript twice, and on the other hand, maybe it can help you." ”

Han Shan became interested, "About what?" ”

Xu Weiguang: "On the band definition domain to find the function value. ”

When Han Shan heard this name, he immediately clapped the case and said, "Okay, I'll be your reviewer." ”

How is the Annals of Mathematics also a well-known mathematics journal in China, the papers that can be submitted to this company are obviously not general, the review process has a total of three reviews, after the preliminary review there is a review, and then the final review, the steps are very rigorous, there will be no mistakes, but because these papers are to be reviewed for the final review, they must be heavyweights, or mentors, or professors, and they must have a certain reputation in the mathematical community, even if Shen Lang feels that this article has no problem, He also did not have the means to proceed to the final review step.

He was qualified enough, but not enough to leave his name on the final review of the Annals of Mathematics.

Most of the final reviewers are professors from major universities, and they take time to review one or two days every month, so the manuscript submitted in the same issue, as long as the number of manuscripts on the day reaches the standard, then it may be that someone else is the first to pass the review, and you still need a month or even two months.

Fang Chao would not have thought that when he and his girlfriend went out to play, the effect of 500% of his luck value had already begun to take effect imperceptibly.
