My Sister is a Big Star

Qin Ze looked in from the door. This classroom was no different from ordinary classrooms, except that the desks and chairs were cleared to the back of the classroom. Only four or five desks were left with notebooks. The students at the desk looked up, or It's doing your own thing with no distractions. Professor Li is in his fifties, with white sideburns, splayed eyebrows, and a pair of rustic round-frame glasses. He looks like a very serious and difficult old scholar.

  He looked away from the computer, turned his head and looked: "Come in."

  Qin Ze nodded and walked to the podium.

  Professor Li supported the frame and looked at Qin Ze: “It’s a junior this year, and it’s time for an internship in the second half of next year.”

"Yes, so I want to exercise myself in advance." After Qin Ze finished speaking, he suddenly realized that he did not have a trace of nervousness. According to his past urine, he was scrutinized by the professor's sharp eyes, not to mention that his legs were trembling. A little cautious, but he was very calm, calmly surprised even himself.

  Professor Li nodded, "Although your dad greeted me, but let's discuss the matter, there should be no less assessments."

He took out a stack of A4 papers from the drawer. There were many topics listed on it. He picked out a few and passed them to Qin Ze: "This is a small part of the problem in this model. It is relatively simple and easy. Take it and take a look. , I will give you two hours, pick two questions at will, and calculate the analytical equations. Xiao Liu, give him a pen."

  The female student who opened the door immediately handed over a pen.

  Qin Ze didn't talk nonsense. He looked around and found that there were no extra seats. So he went to the back of the classroom and moved a desk out of the classroom on his own.

  Qin Zepu calculated the equation on the draft paper, and looked at the content of the subject from time to time. Several times, he saw that he wanted to calculate the complete equation, but had to start over again.

  Digital and analog is a very profound knowledge, and what he is doing now, not even digital and analog, is just a small step in the 25,000-mile long march. Mathematical modeling, also known as mathematical modeling, is essentially an important means of using mathematical tools to solve practical problems. Besides, the popular point is to use mathematical language and methods to establish "equations" for certain things and certain phenomena. For example, if a mathematician wants to predict the weather, he can collect data, build a huge digital model, and use the digital model to calculate tomorrow's weather.

  Of course, this is just a metaphor. The real weather forecast is far more complicated than this. But in fact, the Bureau of Meteorology is a huge mathematical model.

  Economics and mathematics are inseparable. Mathematical model is also one of the very high and very wide applications.

  Qin Ze calculated for half an hour, sweating on his forehead gradually, and finally touched the right direction. The mathematics is too shallow, and many formulas have to be racked before they can be remembered. If Baby Qin is here, he must hum and push on Qin Ze's head and say: "You will kill the old lady, and it will be done in minutes."

  It is said that men are naturally logical and women are perceptual, so men are strong in science and women are good in liberal arts. But this rule rested on the Qin family siblings completely reversed. Qin Baobao has been top-notch in mathematics since he was a child, and has never fallen out of the top three grades. He claims to be the queen of science. Qin Ze is better in liberal arts. The most brilliant deed was that he won the third prize in the National Middle School Student Composition Competition that year.

  Fortunately, he knew that he was not a smart person, he was diligent and able to make up for his clumsiness, and he did not abandon himself, so he was not embarrassed by two questions that could block 50% of college students.

  Time is fast. With the assistance of his assistants, Professor Li promotes the modeling progress little by little, and sometimes holds small meetings, but these have nothing to do with Qin Ze.

Two hours later, Professor Li seemed to think of Qin Ze. He walked off the stage and came to his desk without speaking. He picked up his paper and looked at it. The answer to the equation was written on a blank sheet of paper. The handwriting was neatly written, and Professor Li had a look. Just like meticulous. Looking at the draft paper again, there are densely packed calculation formulas without any blank space. Qin Ze's mathematics was trained by the master with a whip.

  "It's okay!" Professor Li nodded, put the paper back on the table, turned and walked back to the podium, "Stop the work at hand."

  Five or six assistants looked up.

  "Introduce a new member, Class 7 of the Department of Finance, Qin Ze, your younger brother."

  Qin Ze stood up and said politely: "Please take care of me."

  Sparse applause.

  Professor Li said again: "Yang Chen, you will take the younger brother first these few days, so that he can figure out our project this morning. I will have classes later, so let’s go."

  A boy wearing a blue T-shirt and light white slacks nodded and smiled: "I know the professor."

  Professor Li left.

  Before coming here, the old man has already told Qin Ze in detail that it is impossible for Professor Li to do everything by himself for a huge mathematical model, so he needs an assistant. The assistant’s salary is 200 per day for a week. After the mathematical model is completed, he can get one thousand four.

  Professor Li was originally unwilling to recruit students at school. Several of his assistants are all senior interns, who will graduate next month. It was because of the face of the old man that he agreed to let Qin Ze give it a try.

  Qin Ze waited in his seat for a while, and saw that the senior named Yang Chen was immersed in work, so he took the initiative to walk over and called "senior".

  Yang Chen glanced at him, took out a pile of materials from the drawer, and said, "You can take a look at it first."

  Qin Ze had to take the information back to his seat and chewed patiently. A good private equity firm should have its own professional market analysts. It can be seen that the private equity firm commissioned by Professor Li is small. To build a complete digital model requires massive formulas and data. Mathematics is the most rational thing in the world, and every step requires repeated scrutiny. Qin Ze's group is responsible for the rate of return and risk evaluation.

  In addition to the not-so-detailed summary, there are a series of symbol explanations in the information. Qin Ze looked a little strenuous, took out his mobile phone, searched the Internet, and translated one by one.

  The meal arrived in the blink of an eye, and the seniors and seniors in the classroom went to the cafeteria to solve the food and clothing problem. Qin Ze wanted to take out the strength of hanging his head to pierce the beam, and immerse himself in studying, but was driven out for dinner by the senior sister in charge of the key.

  Because of the limited time, he casually ate some food and hurried back to the classroom.

The classroom door was vacant, revealing a crack. As soon as I was about to push the door to enter, I heard someone inside say: "Brother Chen, what is the new way? We have worked hard for a month to build this digital model, and it’s before the delivery time. It's been just over a week, good fellow, he jumped in abruptly to earn our labor costs."

  The guy who spoke was also from Qin Ze's group, so the name was unknown.

  Yang Chen snorted, “His dad and Professor Li seem to be in the same office. They are related to each other. Come here to learn more and get some pocket money.”

   "Our group also has a bonus of 10,000 yuan, and he just divided it over 1,000. Grandma's is enough for half a month's rent."

  "Aren't you still living in the dormitory."

   "Then you can also come to the big health care twice."

"Don't worry, he has a task today. He hasn't even figured out the basic situation. Then I will assign some topics to him. He will not be able to complete it. Hehe, Professor Li must be unhappy. I will come a few more times, maybe it will Will kick him out."

  Qin Ze's face turned black, and he said in his heart that these two little chicks. He silently went downstairs and wandered around the teaching building, sighing in his heart that there are rivers and lakes where there are people. This kind of fighting without swords, lights and swords has become more cruel after going to university. No, there are fights and killings everywhere in life, and elementary and middle schools are no exception. It's just that when I was young, I liked to show it in a violent way.

  Qin Ze didn't like this kind of intrigue hidden in the dark, he hadn't adapted yet.

   Ten minutes later, he went upstairs to enter the classroom, and the seniors and sisters basically came back. The senior sister named "Little Liu" smiled at him, and Qin Ze returned a polite smile.

  There was a professional get out of class at 1:30 in the afternoon. After class, Qin Ze refused the invitation of his roommate to open the black online, and plunged into the modeling data pile. Although he is not the kind of talented science expert like Qin Baobao, there is one advantage that the old man praises: there is peace in every big event! This is what the old man himself complimented him.

  At five o'clock in the afternoon, Professor Li came back, and the groups were assigned tasks. Before announcing the end of today, it was rare to think of Qin Ze.

  "How do you look at the content of the information on the rate of return and risk assessment?"

  "A person is blind, but I haven't eaten it thoroughly yet." Qin Ze said.

  Professor Li frowned suddenly, and looked at Yang Chen: "Didn’t you let you take him."

  Yang Chen looked innocent: "I gave him the information and asked him to ask me if he didn't understand, but he didn't have any problems all day long. I thought Qin Ze had a solid foundation, and he knew how to do it all by himself."

  Nima, when did you say this.

  Professor Li took a look at Qin Ze, and said nothing, announcing that today’s work is over, Professor Li’s calm and calm attitude made Yang Chen a little disappointed. Only Qin Ze can faintly guess his thoughts. In fact, the modeling is nearing the end, and the lack of assistants is true, but how is it possible to invite a half-hearted man like Qin Ze to join the group, mostly for the sake of the old man. The old man also said vaguely that day: Ask him if you don't understand.

  So it doesn’t matter if Qin Ze is messing around, Professor Li doesn’t matter, his dad is behind the scenes to help.

  Qin Ze asked Yang Chen for the information, but he did not refuse, and handed him a pile of copies. A college student, just looking at the information, can he tell if the flowers are coming?

  It was too early after the team broke up, and he spoke on the chat group: "Liberation!"

  A moment later, Li Liang replied: "Come on, we need you to preside over the overall situation, motherfucker, can't help them."

  Zhao Baliang followed and replied: "I can't take you. Brother is one against three, and he will never retreat. When I look back, Nima, where are my teammates? All my teammates died back to the hot spring."

   Then Liu Ziqiang: "I will watch you pretend to be coercive and not speak."

  Qin Ze raised the corner of his mouth, put the phone back in his pocket, carrying a shoulder bag, and trot towards the Internet cafe.

  Familiar location, three familiar animals. With a cigarette in his mouth, he leaned leaning on the sofa chair. Because he was waiting for Qin Ze, Li Liang took the time to watch the video of the game. Zhao Baliang opened a small window to watch Liu Ziqiang, an island nation, playing with his mobile phone.

  Qin Ze habitually smoked, turned on, and squinted his eyes.

   "Summer vacation is coming at the end of the month. You said you were messing about. Be careful to hang out." Li Liang took a bit of a cigarette.

   "To earn some pocket money, I can't always let my sister raise it." Qin Ze took out the mineral water from his bag, and each gave a bottle.

   "Investment modeling is not good, there are too many factors to consider, how did you feel on the first day?" Liu Ziqiang, the best performer compared to the other two, unscrewed the lid and took a sip and asked with a smile.

   "It doesn't matter whether it is difficult or not, but today I met a **** and I was in a bad mood." Qin Ze vomited.

  "You have a story, but I don't have a drink. Let's listen to it?" Li Liang invited Qin Ze to join the game on the computer by the way.

   "It's just a ****, I will find a chance to fiddle with him." Qin Ze curled his lips.

  "Be sure to bring eight taels at that time, and use his human cannon to poke the chrysanthemum." After Li Lianggang finished speaking, he suddenly made a fuss and cried out: "Neurotic, why are you inviting a rookie."

  A guy with an ID called "Little Man Yao" got into the camp, and it was the bronze dish B that pitted them that day.

   Xiaomanyao enthusiastically spoke in the room: "Long live long live, God, you are finally online."

   "Great God, you guys are black."

   "The little girl kneeled for three sets today, and she dropped again."

   "The great **** takes me on the sub-point and takes me to fly, and they will start a video with you."

  The three animals were unwilling to pay attention to her, and even Zhao Baliang, who lacked love, did not bother to talk to her. There are too many shemales on the Internet these days. The thought of a rough man on the other side of the screen makes it disgusting.

  Qin Ze replied playfully: "Nude (harmonious) chat?"

   "I hate it!"

  When the screen goes dark, enter the game.
