Time back to two days ago, on January 28, Hanzhong University, Wang Xiaofei simply packed her luggage and prepared to go home for the New Year.

She is really busy this year, writing her doctoral dissertation, and wants to graduate successfully next year.

The Ph.D. is said to be graduated in three years, but there are very few who can actually graduate on time after three years. Not only is it difficult to pass the doctoral dissertation, but the supervisor also hopes that his doctoral students can study for two more years.

As for the reason, of course, it is that I am not good at school, and I need to continue studying. In fact, part of the reason is that it is difficult to cultivate a few high-end talents, which are the most important labor force under the mentor, and it is free!

Do doctoral students dare to do their best to help their supervisors do their best, and whether they can graduate successfully depends on the face of their supervisors......

Xiaofei Wang majored in statistics, and her doctoral dissertation was titled "Implied Valid Estimation of Autoregressive Error Distribution Functions and Simultaneous Confidence Bands"

The implied effective distribution function estimator constructed using residuals is still smooth, and a smooth simultaneous confidence band is constructed based on its implied validity. This paper not only embodies advanced statistical theoretical skills, but also has great application value, because it can use an accurately estimated error distribution function to generate random errors to simulate complex random phenomena......

Well, the average person can't understand it.

In short, in the past year, she has basically been a dormitory-library-tutor project team-cafeteria, four points and one line. For a whole year, the number of times I left the school was only a handful.

In a person's life, there are only two stages of study that are the most strenuous in life, and of course, most people only have the first stage.

The first stage is high school, the college entrance examination is an important threshold to change life, and most people work very hard at this stage. Waking up at 5 a.m. and going to bed at 10 p.m. is commonplace, and no one shouts that it's too hard to eat or anything.

The second stage is when you are studying for a doctorate, and most people do not have the opportunity to go through this stage. But those who have experienced it know that it is harder than in high school. After all, the knowledge in high school is relatively simple, you just need to work hard.

The things I learned at the doctoral level are much more profound, and they are all the most cutting-edge knowledge in the same field. It's just that hard work is not enough, you also need to have talent, otherwise you basically won't be able to finish your job. The exception, of course, is certain schools with a "relaxed" academic atmosphere.

Hanzhong University, as one of the top universities in China, has very strict academic requirements, and Wang Xiaofei's supervisor can graduate successfully in three years.

Before going home during the holiday this time, Wang Xiaofei also went to the tutor's house according to her father's arrangement.

At that time, when my father called to talk about this, Wang Xiaofei was still a little resistant, and people who are scholars are a little high-minded, and they are not used to this kind of thing.

But in the end, I was persuaded by my father, this society is like this, people are in contact, if you don't communicate, there will be no favor. Especially now, others hold the power of life and death, and whether they can graduate successfully or not basically depends on the opinion of the mentor.

To be a favor, Wang Xiaofei's subsidy is not enough, or the money given by her father for support. When she received the transfer notice, she was still surprised, because her father transferred a full 20,000 yuan!

She and her mentor made an appointment in advance, at four o'clock in the afternoon on weekends.

When I came downstairs to the tutor's house on time, I met my senior brother Liu Jun. Liu Jun was a doctoral student a year earlier than Wang Xiaofei, and his supervisor did not arrange a defense for him this year, and he wanted to work hard again next year.

He also came to the tutor's house today to contact his feelings, and he just came out. This time I came to visit the mentor, and he brought a case of wine, the box was not large, six bottles. But that's Moutai, and such a small box is five or six thousand yuan!

Liu Jun glanced at Wang Xiaofei and saw that she was empty-handed, so he felt disdainful. These nerds, reading are stupid, it's almost the New Year, and when you go to the tutor's house, you are empty-handed, and you will see how you graduate next year!

He greeted with a smile: "Classmate Wang, are you also going to the tutor's house?"

Wang Xiaofei has a general impression of Liu Jun, because he usually doesn't pay much attention to his studies, and he doesn't work hard when he does projects, and he is relatively slippery.

said lightly: "Yes, I'm going home for the New Year soon, come and meet with the mentor and say something." ”

"Oh, then you don't pay attention to this, how can you come empty-handed for the New Year, even if you can't afford Moutai or something, it's good to carry a pot of sesame oil, isn't that a specialty sesame oil in your hometown." Haha~" Liu Jun smiled proudly.

Wang Xiaofei ignored him and went upstairs directly.

"Phew, nerd, tall fart, do you really think that doctoral graduation depends on good thesis writing?" Liu Jun looked at Wang Xiaofei's back and said contemptuously.

Knocking on the door of the tutor's house, the mentor's wife greeted him.

"Xiaofei, you're here, your teacher is in the study. ”

My wife is over 60 years old this year, she is in good spirits, a little old lady dressed in a very foreign style, and she is also very kind.

Wang Xiaofei smiled and said a few words to her wife, and then walked into the tutor's study.

The tutor is also the number one person in the academic world, and he is also in his sixties, with a ruddy face and black hair, and it seems that he can still struggle in his career for a decade or two.

Seeing Wang Xiaofei come in, he put down the book in his hand and greeted her to sit down kindly.

"Xiaofei, are you going home for the New Year? You are also working hard this year, it seems that you have never asked for leave to go home. ”

"Aren't you going to write a thesis this year, and your project is also at a critical moment, so I really can't leave. I thought that if I put more effort into this year, I will be able to graduate more confidently next year. Wang Xiaofei replied.

She also revealed the information that she wants to graduate next year, if you don't say this, the tutor will not help you arrange the thesis defense.

"Oh~ It's not easy to graduate with a doctorate, this matter involves a lot of things, you know. The instructor said slowly, picked up the teacup, and sipped the tea leaves with the lid.

After listening to the words of the mentor, Wang Xiaofei knew that it was useless to just talk about it, and she had to take out something real.

"I will do this aspect of the dissertation seriously, and it is up to you to arrange the defense. By the way, the Chinese New Year is approaching, and I don't know what New Year's goods are still missing at the teacher's house, so I bought some shopping cards at RT-Mart next to me, which can be regarded as a little affection for the student's master and wife. ”

As she spoke, she pulled out a small box from her small backpack. Not an envelope or a red envelope or anything, but a box.

RT-Mart shopping cards are divided into several faces, 100, 200, 500, 1000 four kinds, Wang Xiaofei bought the largest denomination of 1000, 20,000 yuan to buy 20.

It's a prepaid card, stacked in a thick stack of 20 cards.

Seeing the "1000" face value printed on the box, and then looking at the small box with an astonishing thickness, the mentor's eyelids jumped.

He put down the teacup in his hand and said in a loud voice: "Look at you kid, just come and see me and your wife, and bring something with you, take it back and take it back! ”

Wang Xiaofei naturally couldn't really take it back, she said in a sincere tone: "The teacher and the teacher are like my elders, they have taken care of me for more than two years, and now that the New Year is over, it is also appropriate to honor you." ”

"Haha~ You kid, okay. Come over in the next year, after you finish writing your paper, bring it to me and I'll help you revise it. ”

Wang Xiaofei was overjoyed, the tutor showed his attitude, since he was willing to help him revise his thesis, it means that he will arrange the graduation defense next year.

The two chatted for a while, and Wang Xiaofei got up to say goodbye.

The tutor enthusiastically got up and sent her out the door.

turned around and went back to the room, picked up the small box left by Wang Xiaofei, opened it and saw that it was full of shopping cards with a face value of 1,000, a full 20!

"Good guy, I didn't see it, this Wang Xiaofei's family is quite rich. The mentor muttered to himself.

can work as a doctoral supervisor in a prestigious school, of course, the tutor is not short of money, not to mention the annual income, there are still seven or eight hundred thousand. But no one has too much money.

He now takes in a total of four doctoral students, one every year. As for graduation, it is normal for doctoral students to graduate in 3-5 years. There are very few people who can graduate in three years! Graduation in four years is considered smooth, and graduation in five years is normal.

Originally, the tutor planned to let Liu Jun graduate next year, but that kid will be considered to have been studying for 4 years by next year, and he is usually quite diligent and often runs home. But now that I think about it, students, you still have to focus on your studies, Liu Jun is still a little worse academically, and it's better to study with yourself for another year.

Arrange for Wang Xiaofei to graduate next year, this girl has a good learning attitude, her efforts are obvious to all, no one can say anything about arranging her graduation!

At this time, Liu Jun was still triumphant, he didn't know that he wouldn't be able to finish his job next year!

Wang Xiaofei pulled her suitcase, took the train to Zhongyuan City first, and then transferred to the bus back to the letter. Fortunately, Hanzhong is very close to the Central Plains, so it will take most of the day to toss it like this.

Depart for the train station in the morning, and at about 3 o'clock in the afternoon, the bus arrives at the Xinkou long-distance bus station.

got out of the car and took out her suitcase, Wang Xiaofei heard her father's voice calling her, "Xiaofei, this way!"

Wang Xiaofei looked up and saw her father standing outside the bus station, waving at her.

happily pulled his suitcase out of the station and came to his father's side.

"Let's go, let's go home. Dad said heartily.

The car stopped on the side of the road, and the two came to the side of the car, ready to get in the car and go home.

"Hey, is this car from your company, your company is quite rich, and I even gave you an Audi A6!" Wang Xiaofei looked at the black and shiny Audi car on the side of the road and asked in surprise.

"Haha~ How is it possible, our small company only has a profit of two or three million a year, how can we match me with such a good car, this car was bought by our family!" said my father proudly.

"Did we buy it ourselves, Dad, did you get rich?" Wang Xiaofei was even more surprised when she heard this, and she also knew the situation at home, where did she get so much money to buy a car.

"It's not me who got rich, it's your brother who got rich~" Dad lowered his voice and said mysteriously.
