Lingziding Village belongs to Dayu Township, Anhe County, G Province.

Lingziding Village is nearly 100 kilometers away from the county seat of Anhe County.

To go to the county seat from Lingziding Village, you must first walk a day and a night on the mountain road to reach the seat of the Dayu Township Government, and then you can take a ride to the county seat.

Before going out, Pang Xuelin brought the dry food specially prepared for him by Ah Qing, cornmeal buns, as well as a pot of water and a bag of pickles.

All the way over the mountains and mountains, although the township government of Dayu Township is only 30 kilometers away from Lingziding Village, the real road to go is more than several times.

Along the way, you will occasionally pass through a few villages, dotted among the mountains, and the smoke curls up, giving it a peaceful and serene rural appearance.

In the evening, Pang Xuelin came to a mountain temple for passing tourists to rest and spend the night.

Now that it is approaching the end of the year, there are not a few pedestrians passing by, and when Pang Xuelin arrived, there were about three or four people inside.

However, Pang Xuelin had no intention of talking to them.

Corn bun mixed with water, plus pickles, and dealt with a casual meal.

Nothing was said all night.

The next day, Pang Xuelin continued to set off until two o'clock in the afternoon, when he arrived at the location of the township government of Dayu Township and caught the last bus to the county seat.

Wobbly all the way.

When I arrived at the county seat, it was already six o'clock in the evening.

Pang Xuelin found a small hotel with a big shop for five yuan, ran with hot water beautifully, and then slept all night in a room filled with the smell of feet and snoring.

Early in the morning, Pang Xuelin was woken up by those who got up early in a hurry.

He had no choice but to get up, eat a soy milk bun on the street, and then rush to the Anhe bus station, spending twenty-four yuan to catch the shuttle bus to the provincial capital Lincheng.

Pang Xuelin had inquired before, and the Anhe County Post Office did not open international mail services, so he could only rush to the provincial capital and find the post office to mail his papers.

On the evening of the third day after departure, Pang Xuelin finally completed the journey of hundreds of kilometers from Lingziding to Lincheng.

It was already evening when he arrived in Lincheng, Pang Xuelin first dealt with it casually on the street, and then found a small guest house to stay.

In this era, although the urban population of Lincheng exceeded two million, the level of urban construction was completely different from that of the previous life.

The 30-storey department store is the tallest building in Lincheng, and there are only a handful of high-rise buildings with more than 10 floors in the entire Lincheng.

There are messy power lines on both sides of the road, especially at the end of the day, the streets are full of bicycles, and from time to time you can see airbag buses and trolleyless electric buses parade through the streets.

The room rate of the guest house costs twenty-five yuan per night, and Pang Xuelin must finish what he has to do as soon as possible, otherwise he will not be able to cope with this amount of money for many days.

On the morning of the next day, Pang Xuelin went straight to the Lincheng Post Office to handle the international mail business.

This time, Pang Xuelin also submitted his paper to the Annals of Mathematics in Princeton.

The four major international authoritative academic journals in the field of mathematics are Annals of Mathematics, New Advances in Mathematics, Acta Mathematica and Journal of the American Mathematical Society.

The reason for choosing the "Annals of Mathematics" is that on the one hand, the authority of this journal, on the other hand, the "Journal of the American Mathematical Society" has just been published for a few years, and there is still a certain gap between its influence and the "Annals of Mathematics".

Therefore, the Annals of Mathematics is the best choice.

Unlike the real world, in the nineties, it was not easy for mathematical researchers in Chinese mainland to publish an article in four major journals.

Since the founding of the People's Republic of China, the papers published in the four major journals have been counted in one slap.

Even in this era, as long as you publish a paper in one of the four major journals, you are by default eligible to run for academician of the Chinese Academy of Sciences.

Therefore, as long as the paper can be successfully published in Annals of Mathematics, the situation of Pang Xuelin and even the entire Lingziding Primary School will be changed dramatically

A handwritten paper of more than 60 pages in English will take more than a month to travel from Lin Cheng to Princeton at the earliest.

The young girl who helped Pang Xuelin handle the international mailing business looked at Pang Xuelin with scrutinizing eyes from time to time.

A beautiful English calligraphy, dozens of pages of handwritten English articles, plus Pang Xuelin wearing an old army green coat, the appearance of a dusty servant, how to look at it.

"Comrade, there's nothing wrong with the document I'm going to mail, right?"

"Oh, it's okay!"

The girl stamped the payment slip and said, "Take this bill and pay at the window opposite it, and give me the receipt after paying the money." ”

"Okay!"

Pang Xuelin looked at the postage of 124 yuan on the payment slip, and couldn't help but feel a little painful.

However, he still happily paid the money and left, which was nothing compared to the harvest.

After the international mailing business, the remaining dozen articles have to be submitted to domestic journals, but compared with submitting papers to the Annals of Mathematics, it is more troublesome to submit papers to domestic journals.

Because Pang Xuelin didn't know the specific addresses of these journals at all.

Even if you remember the addresses of your previous life, but in the next few decades, China will change so much, God knows if these addresses have changed.

After thinking about it, Pang Xuelin still decided to go to Lincheng University to see if he could find someone to help.

Although Lincheng University has entered the list of 211 project construction in later generations, because it is located in the west, its attraction to talents is limited, and the overall strength of the school is not strong.

Pang Xuelin walked around Lincheng University for a long time before he got the location of the teaching building of the Department of Mathematics from a student.

After entering the teaching building, the class bell rang, and seeing a large group of students pouring into a staircase classroom, Pang Xuelin hurriedly followed in, and then found a place to sit down at random.

This is a big class, composed of students from several classes, more than a hundred people, no one knows anyone, except for the occasional student who looks at him a few times because of Pang Xuelin's clothes, no one notices him.

At this time, a middle-aged man wearing glasses and a somewhat bald head walked in and said: "Today is the last class of functional analysis of this semester, and the exam will be taken after this class. ”

There was an uproar in the classroom, and the students took out their pens and papers to prepare for the record.

The real function has been studied ten times, and the functional analysis is chilling.

This is not something that is said casually.

As the basic courses for entering the door of modern mathematics, these two courses are basically similar to the book of heaven for many mathematics students.
