At the banquet after the show, Li Fan was basically in a state of "stamp collecting".

Before he came to Zhehe, he specially bought a Polaroid, which is a camera that presses the shutter and directly produces photos.

He took a photo with the stars with his camera and asked for an autograph on the photo.

"Sister Zhi, please sign for me, it's an honor to be on the same stage with you. ”

"Teacher Zhang Yi, your play is so full of life, I will serve you and help me sign it?"

"Huang Ama, you shoot a few more dramas, I especially want to revisit your domineering eyes and ask for an autograph!"

……

Li Fan asked for an autograph at the table, and when he returned to the hotel room, Zhang Xiaofei asked in surprise: "Roar, Brother Fan, it turns out that you are so old, you are a fan of the stars of that generation! I thought that our post-00s all liked Xiaolulu." ”

Li Fan said: "I respect my predecessors, but I don't fan them." ”

Zhang Xiaofei was stunned: "Then you, why did I see you asking for an autograph for the first time?"

"Hey!" Li Fan smiled and began to show the photo in his hand, "This is my mother's idol, this is my father's dream lover, this is my aunt's dream old man...... It's all memories of their time, and I'm asking for autographs for them. ”

"Oh...... I see, I thought you were a fan of them, you look at those teachers and see that you want to sign autographs, tsk, Brother Fan or you still have a set. ”

"Don't be too strong, let's see when the earliest plane is tomorrow, hurry back to the capital, the south is cold and cold, and the temperature difference between day and night can't adapt to it for the time being." ”

"Don't you need to ask Guan Tong about them?"

"They and we are not all the way, Guan Tong is going to visit the crew tomorrow. ”

"Great," Zhang Xiaofei pricked up his ears and listened outward, then lowered his voice and said, "Guan Tong is a good person, but it's like a time bomb, you can't say when you can't go down." ”

Li Fan grinned, "Sometimes speaking is unguardable, small flaws." However, people are good, and people are good. Talking thieves and beautiful people are bastards, which is the most disgusting. ”

Zhang Xiaofei glanced at a stack of photos in Li Fan's hand, and asked hesitantly: "Brother Fan, in our family, whose dream lover is Teacher Zhang Yi?"

"Hey, here you go, no one asks me for him, but I can't let go of any of the old artists, lest they have an idea in their hearts. Li Fan took out the photo and handed it to Zhang Xiaofei, but his hand suddenly hovered in the air, and suddenly asked, "Do you want to take a group photo?"

"Huh?"

"Let's go, I'll take you to Mr. Zhang Yi to take a group photo!"

"Brother Fan, love you, hurry up, my man ran away in a while. ”

As soon as the two of them walked to the door, Zhang Xiaofei suddenly turned back into the bathroom, began to comb his hair in front of the mirror, and carefully brushed it up.

Li Fan shook his head, the little girl chasing stars is really scary, he glanced outside the door, and suddenly said, "Teacher Zhang Yi, what are you ...... Oh, catch a plane, then I'll talk about it later. ”

Bang!

There was a loud bang.

Li Fan hurriedly shifted his gaze back indoors, but saw Zhang Xiaofei covering his forehead like the wind, blowing past him, and the glass door of the empty bathroom creaked and "trembled".

"Brother Fan, you lied to me!!"

Li Fan laughed: "Okay, this time I don't need to put on makeup, this bag can't melt." ”

……

After fulfilling Zhang Xiaofei's wish, Li Fan returned to the bedroom, and when he turned on the computer and was about to write, his mobile phone rang, and it was Lu Yi calling.

Lu Yi, the host of the famous talk show "Lu Yi has an appointment", one of the top ten famous female hosts in China, is very famous and has a wide range of popularity.

But for her hosting skills and business level, there are praises and steps.

Maybe the female host is more concerned than the male host, and the topic is higher, except for the female host on the job of Beijing TV, the business level of the female host in other systems is controversial.

Lu Yi is one of them.

Lu Yi was put on a big hat by netizens: the queen of sorrow.

It's not that she's sad, it's who she interviews.

Interview with a famous entrepreneur, the entrepreneur's factory soon broke the capital chain and declared bankruptcy:

interviewed a famous couple in the entertainment industry, and as soon as the show aired, the two announced that their relationship had broken down and divorced.

even interviewed the founder of a famous foreign cloud service, and soon after, there was a huge security breach in the cloud service, and countless private photos of popular celebrities were circulated on the Internet.

……

So, netizens ridiculed this man for having a bad omen.

Actually, this is a joke, she doesn't have a spell, after all, Lu Yi interviewed too many elites in various industries, it's normal for someone to have something happening, and netizens also love to do things.

Lu Yi called Li Fan very simply, just to see if he could spare a day to help record "Walking with Big Coffee".

Originally, this show had been pushed to January, but because the production team wanted Li Fan to become famous as the first celebrity to appear in the show, Lu Yi personally called to discuss.

Lu Yi said on the phone: "Our recording is at Beijing University, that is, to record your daily life in a day, talk about the past 2 taels of experience, and it will not consume too much of your time." ”

Li Fan counted the time and said, "Okay, Sister Yi, are you sure that you will be at Beijing University all the time?"

"Whatever you want, if you lead us somewhere else, we'll follow you. ”

"Oh, Wednesday and Thursday, I was at school. But on Friday, I will go to Gongsu Satellite TV to record "The Strongest Brain". ”

Lu Yi was overjoyed and said: "Okay, you can say it! When we go to record, we won't say hello in advance, just "visit", and you can be ready to meet the enemy in those two days!"

"Okay, no problem!"

After putting down the phone, Lu Yi happily shook his mobile phone to his colleagues in the office, "It's done, on Wednesday and Thursday, Li Fan can spare a day!"

"It has to be Sister Yi, we are all in vain!"

"Sister Yi's face is so big, can our little choreographer compare?"

……

Lu Yi smiled: "Okay, let's go to Beijing University on Thursday, you guys prepare in advance." Oh yes, what Li Fan likes, let's buy some gifts for him. ”

"Aren't you and the big agent Jiang Dan good sisters, ask Mr. Jiang. ”

Lu Yi called Sister Jiang, but Sister Jiang replied with a smile: "He loves money, just kidding, Li Fan doesn't have any special hobbies, you can do whatever you want...... Really, he doesn't have any particular favorites. ”

Lu Yi put down the phone and had a headache, what to send?

A choreographer suggested: "Cultural people like to drink tea, and it's not wrong to send some good tea." ”

Lu Yi agreed, and then went to a famous store to carefully select tea.

……

After returning to the capital, Li Fan plunged into the library and began to recharge his batteries for the final exam.

No matter how busy you are, you can't forget that you are still a student, and you should attend classes and take exams. No matter how hot you are, even if you burn the sky half red one day, you can't help but recharge yourself and give up your efforts.

Li Fan has always felt that only by constantly enriching himself and improving himself can he make his life more exciting and stable. After all, your appearance can't make you popular for a lifetime, and after more than ten years, what should you do when you are "old and decrepit"?

It turned out that Li Fan's idea was completely wrong and he was overwhelmed.

First of all, he didn't just rely on his appearance to become popular, of course, if he was mediocre, it would never be so popular. (Well, the truth!)

Secondly, there are two kinds of handsome, some people are handsome from young to old, and they have a charming demeanor at all stages of life. There are also some people who are just young and peerless, but middle-aged and elderly people have a big belly. But Li Fan is obviously the former.

On a long table in a hidden corner of the study room, in the northeast corner, there is always a copy of Hugo's "Les Miserables" placed near the window to occupy a seat.

Although the study room of Beijing University clearly stipulates that no seats are occupied, and there are administrators who repeatedly check and confiscate books every day, this "Les Miserables" is not tragic at all, and has successfully escaped round after round of "searches", and it will always remain there, no matter how long the owner has not been to the study room.

Because, this book is Li Fan's!

As long as there are people, there are privileges, and the same is true for the study hall in Kyoda-ri.

Li Fan held a stack of books on the table, he took off his down jacket, sat on the chair, and then picked up the first book and read it carefully page by page.

This large and huge table can seat 12 people in front of and back, and when Li Fan, who has not shown up for two or three days, appears, some of the classmates who were still reading with peace of mind before became "absent-minded".

After a while, a girl quietly walked up to Li Fan, patted him on the shoulder, and said, "Classmate Li Fan, I'm sorry to disturb, can I ask you a question?"

Li Fan raised his head, "Oh?

"I've read your academic research before, and you have studied the ancient "public car" in your article, but I think the structure of the public car map you have studied is wrong. ”

Li Fan was overjoyed, "Yes, tell me your opinion." ”

"Can I use your pen and paper?"

"Of course!"

……

At a nearby table, two male classmates whispered:

"Li Fan really monopolizes the eyes of all the girls in our school, and I envy me to death. ”

"There is no way around this, who calls people talented and good-looking? Talent in all aspects, there is no solution. ”

"That's not necessarily, believe it or not, can I ask Li Fan to stop?"

"Bragging. ”

"Make a bet!"

"Bet, bet on what?"

The tall boy thought for a moment, "If I lose, I'll invite you to a restaurant outside for a big meal, what if you lose?"

The fat boy thought for a moment: "If I lose, I'll give you my 2 G USB flash drive for a few days!"

"Big brother, what age is it, in ancient times? USB drives have started with 8 Gs, why do you tease me with 2 Gs?"

The fat boy lowered his voice and said mysteriously: "There are 2 G love martial arts movies in it!"

The tall boy pouted, "Dude, are you cave man on the top of the mountain?"

The fat boy's voice was lower, "I'm talking about 2 G seeds!"

The tall boy was startled and slapped his thigh, "That's it!"

"What question do you want to ask Li Fan?"

"Let me think about it first!" the tall boy thought for a long time, then his eyes fell on the book of Advanced Mathematics on the table, and he pointed, "That's it." ”

"Your uncle, he is a liberal arts student!"

The tall boy picked up the book and got up and said, "No matter, for 2 G seeds!"

"Eh, don't let people beat them up. ”

"He's a big celebrity, and he doesn't dare to cut me. ”

……

The girl and Li Fan discussed the structure of the car, and after being taught a lesson by Li Fan, she nodded with a smile, raised her thumb and said, "Li Fan, you still have a reasonable and well-founded statement." ”

Li Fan smiled: "Your ideas are also ingenious. ”

The girl smiled and turned to leave.

Li Fan just lowered his head and flipped through the two pages of the book, but when he heard someone in front of him, he whispered, "Classmate Li Fan, can I ask you a question?"

Li Fan put the gel pen in the book, looked up and saw that it was a thin and tall boy, and he smiled: "Yes." ”

The boy smiled brightly, the seeds were in hand, he put the advanced math textbook on the table, and said, "You can help me see how to solve this problem." ”

Li Fan was stunned for a moment, high numbers......?

In the textbook, this question circled by tall boys made Li Fan confused:

Try parameter a & gt; In the case of different values of 0, the number of real roots in the open interval (0, 1) of the equation x3 −3ax+a=0 is determined, and the reasons are explained.

Li Fan frowned when he saw this, and said, "You wait for me to analyze it in a few minutes!"

"Okay, there's no hurry. ”

The tall boy saw that Li Fan suddenly turned the textbook of "Advanced Mathematics" to the first page, and then, when he saw it, the textbook quickly turned page by page, Li Fan did not raise his head, his expression was focused, and his slightly long black thick hair was so clean that there was no trace of impurity.

The tall boy secretly said in his heart: I only hate that I am a man, if it is a woman, I like it too!

In just five minutes, Li Fan flipped to the page number of this question, he stopped, took out a pen and paper and said, "Let me tell you?"

The tall boy was dumbfounded for a moment, "Huh?"

"Didn't you ask me how to solve this problem?"

"Ahh

"Look, I'll show you the steps to solve the problem. ”

"Ahh

On the A4 paper, the gel pen rustles, and the steps to solve the problem jump on the paper:

Solution: Let f(x)=x− 3ax+ a, obviously f(x) is continuous and derivable over the interval [0, 1], and f′(x)=3(x+√a)( x-√a).

(1) When a≥1, f(x) has no station in the interval (0, 1), and f′(x)& lt; 0, while f(0)=a 0& gt; ， f(1)=−1 2a& lt; 0，

（2）……

...... When f(√a)=a(1-2 √a)& lt; 0, and f(1)=1- 2a≤ 0, i.e., 1/2≤a& lt; At 1, f(x) has only one zero point in the interval (0, 1),

In this case, the original equation has only one real root in the interval (0, 1).

The whole problem-solving process was written, and the tall boy was also confused, and the seeds of 2 G's were gone, Li Fan, you ...... You're a little too powerful!

Li Fan said: "The auxiliary function and interval of this problem are very obvious, because we want to study the number of real roots, so let's roughly describe the graph of the auxiliary function, but only need monotonicity and extreme values, without considering the concave and convexity and inflection point, so only the first derivative is needed, and then discuss it according to the different values of a, which is very simple." ”

Tall boy: "Ahhh

Li Fan said with a smile: "Aren't you usually taking this class much? This question is a basic question, if our students at Beijing University listen to it casually, this question will be caught, I guess you must not have taken much high math class." ”

"Uh, that, ha!

Li Fan said again: "Actually, high mathematics is quite simple, it is the introductory popularization textbook of the university, and there are too few dry goods in it. ”

"Oh, that, classmate Li Fan, thank you, you're busy, I won't bother. ”

The tall boy hurriedly slipped away, pricking his heart.

Li Fan smiled lightly, then unfolded the book and continued reading.

As there were fewer and fewer books on the desks, the hands on the walls of the library ticked to 5 o'clock.

Li Fan, who was concentrating on reading, suddenly had a familiar faint smell of perfume in his nostrils, and he hurriedly raised his head, only to see Gu Yating standing at the corner of the table fiddling with her mobile phone.

"Oh, you're from Xi?"

"No, look for you, you read the book first, I'll wait for you, and follow me after reading. ”

"Then you wait for me for 5 minutes!"

After reading the last part of the book in his hand, Li Fan closed the book and asked, "What are you looking for me?"

"I'm going to go shopping with you! ”

"Oh, I have clothes, no need. ”

"Put on new clothes for that occasion, let's go. ”

Returned the books in the library, and the two of them walked out of the library together, and when they first came to the door, they heard two students outside, one tall and one fat, grabbing a USB drive.

The fat classmate protected the USB drive and said, "You didn't win me, what are you robbing?"

Tall boy: "Although I didn't win, but I lost with brilliance, that's not Li Fan, who would have thought that a liberal arts student would take any "High Mathematics"!"

"Admit defeat and don't beat my USB idea. ”

"I'll add another project to you, after eating at the restaurant, please karaoke!"

"Give me a little honesty, touch my USB drive again, and I'll eat it." ”

……

Gu Yating asked curiously as she walked, "How does it have anything to do with you?"

Li Fan frowned and shook his head, "I don't know." ”

Gu Yating: "When did you choose "High Mathematics"? ”

Li Fan continued to shake his head, "I didn't fix it, I just read the previous part." ”

The voice was not high, but it clearly reached the ears of the two classmates who were bargaining for the USB drive.

The two polytechnic men looked at the two handsome backs passing by, and then, the haze on their heads seemed to be heavier, and the cold weather seemed to be more thorough.

He said that "High Mathematics" is a popular reading. ”

"Well, I believe it, and I think it is. ”

"He gave me the answer in 5 minutes. ”

"What do you mean?"

The tall boy rubbed his face, "Let me calm down, I feel like I've seen a ghost." ”
