Chapter 7: Wonderful Sichuan Restaurant

Time passed, and on June 20th.
The time required for the three courses of the task is June 23, Complex Function, June 25, Discrete Mathematics, and June 26, Probability.
I have 3 days to test the Complex Function. Liu Fan went to the library for a long time in the morning, and in the afternoon he took the problems accumulated during this time to find Teacher Liu who taught Complex Function.
When I came to the teacher's office, Liu Fan knocked on the door carefully.
"Come in."
凡 Liu Fan came in and there were only three male teachers in the office, and Liu Fan didn't know him.
"Who are you looking for?" One of the relatively young teachers asked.
"Hello teacher. I'm looking for Liu Wei Liu."
"Ms. Liu should be in the shop now." The other party was not sure, you can go to the shop to see.
"In the shop?" Lin Fan grimace, "What shop?"
"The Sichuan restaurant diagonally opposite the school gate." The other side explained, "Go there and look."
"Okay, thank you teacher." Liu Fan glanced at the time. It is now 1 pm. It seems that Teacher Liu may be eating there, so he accelerated his pace and hurried to the school gate.
There is only one Liu Jichuan restaurant diagonally opposite the school gate, which is easy to find.
"Hello, what to eat?" A middle-aged woman entertained as soon as she entered the door.
"Oh, that, I'm looking for someone." Liu Fan said as he swept around the store, Sichuan restaurant is not large, there are a dozen tables in total, and now there are three tables at dinner, but did not see Teacher Liu.
哦 "Oh, who are you looking for? Is that the table?" Aunt asked, smiling at the large round table inside.
"I'm here to find my teacher." Liu Fan smiled and looked at the people in the shop carefully, "I guess the teacher has left, I'll look elsewhere, sorry."
凡 Liu Fan turned and prepared to leave Sichuan Restaurant, thinking about asking the class leader to ask the teacher's phone number, meanwhile, the aunt asked with a smile and said, "Are you here for Teacher Liu?"
"Huh?" Liu Fan just turned around and immediately turned back, "Huh, uh, is Teacher Liu in?"
"Are here, wait a minute." Aunt motioned to Liu Fan to sit down and went to the back kitchen and shouted, "Old Liu, a student is looking for you."
"Oh ~~~"
凡 Liu Fan heard a response from someone inside, and didn't wait long after that, a familiar face came out wearing the chef's obedience to the chef.
"Liu ... Ms. Liu?" Liu Fan looked at Liu Wei's dress and couldn't return for a long time.
威 Liu Wei looked up and down on Liu Fan, and two words came up for a long time, "are you?"
Liu Fan: "..."
"Cough, cough." Liu Fan coughed awkwardly, "Teacher, I am your student, Liu Fan, a junior in information and computing science."
"Oh oh, Liu ... Where ..." It can be seen that Liu Wei worked hard to recall the name, and then thought about it for a long time. He should give up, "Well, what are you doing to me?"
"That's it." Liu Fan didn't want to continue this embarrassing atmosphere, and quickly shifted the topic. "I have some problems that I won't solve, and I have some difficulties in understanding some knowledge points. "
"Oh?" Liu Wei wiped his hands carefully on the apron before taking over Liu Fan's notebook and checking it.
Liu Wei glanced back and forth for a minute or two, wondering if it came out subconsciously, "Student Liu Fan, are you a surname?"
"what?"
哦 "Oh no." Liu Wei looked up and smiled. "I mean, have you eaten?"
"No." Liu Fan responded instinctively, but immediately added, "but not hungry."
This is really not Liu Fan deliberately refraining from eating for lunch. He had a small amount of food. Sometimes he was too busy to be hungry, and then he just waited for the next meal.
Liu Wei carefully placed Liu Fan's notebook on the dining table and waved, "Why can't a young man not eat, let alone you have so many questions for you that you won't be able to get to the evening. Just sit down, come all Here, the teacher will make two special dishes for you. "
凡 Liu Fan felt inappropriate and was thinking about how to refuse, but Liu Wei went straight to the kitchen.
Seeing Liu Fanying's uneasy look, Auntie came over with her warm smile. "You Teacher Liu is happy today. If you are fine, just accompany the teacher for a light meal."
"Are you a master?" Liu Fan asked carefully.
Auntie Wu nodded and motioned to Liu Fan to sit down. Liu Fan still felt that he was a bit out of style, but the teacher had already gone into cooking, and the teacher was persuading again here, Liu Fan was not good at leaving, and he could only watch it change.
After waiting for about twenty, Liu Wei sat in front of Liu Fan with Gongbao chicken, small fried meat, torn cabbage, pig head meat and a plate of peanuts. "I'm afraid I won't cook hard vegetables because I'm hungry. Right. "
"Teacher, you're very kind." Liu Fancheng sat upright with horror, "I'm so sorry for you."
"It's all embarrassing to the grandfathers." Liu Wei waved his hand. "You are all grown-ups, are you afraid of the teacher?"
"This is not living under the control of a teacher since childhood ..." Liu Fan whispered.
"Be a teacher then force you to taste the teacher's skills." Liu Wei said, his wife brought a box of cold beer.
"Can you drink it?"
"A little bit." Liu Fan's alcohol is actually OK, but people who drink often know that they can only drink if they can drink, otherwise they will die on the wine table.
Liu Wei poured the wine and ate two dishes without touching anything else, and took Liu Fan's notebook directly. "Do you understand these questions or do you think they are not a problem?"
"I have a classification." Seeing Liu Wei started to say business, Liu Fan was busy and earnestly, "These are mainly the same as the correct answer I calculated several times, and then there are basic understanding problems in the next few pages. It ’s the hardest thing that I think is that I ca n’t even understand the subject.

"Well." Liu Wei drank a glass of beer, then was silent for a long while, "I probably know your situation, so I will help you to sort out the basic knowledge first, then we will explain the topic in depth, and finally we What do you think of another review? "
"Everyone listens to you." Liu Fan said respectfully.
"Okay, so I will tell you about the problem of the spherical surface first. Many people think that this is a very basic thing, but actually the interesting things are in it ...
Here you mentioned the Cauchy integral formula, Xiao Liu, you have to remember, first of all, you have to thoroughly understand the high-order derivative of the analytical function ...
Well, when it comes to Laurent series, tell me what is his nature? By the way, he is still Taylor series ...
说 You said that mapping is your biggest difficulty now, so let's try to reverse it first, consider the application of mapping, and then talk about the principle ...
Uh ... "
Not long after Liu Wei started giving lectures to himself, Liu Fan immediately jumped out of the embarrassing emotions before, and became very careful to listen to it. What shocked Liu Fan was that Liu Wei ’s explanation was simple and easy to understand, but Liu Fan was After taking Liu Wei's class, he had never seen such a treasure teacher in the other semester's class.
The two of them taught while eating, one speaking carefully, the other listening carefully, drinking beer and eating vegetables, holding the test points and brushing questions.
The business of Liu Jichuan Restaurant is very good. Fortunately, there are other chefs standing in the back kitchen, and Liu Wei Liu Fan, a pair of mentors and apprentices, today has become a beautiful scenery in Sichuan Restaurant. A drunkard who seems to be drinking is talking about a group of college students who have not studied advanced algebra ...
Every college student who came in to eat was a group of black question marks across his face.
WTF?
At night, at night, Liu Wei glanced at the clock on the wall and covered the pen in his hand. "I remember the dormitory closed at eleven o'clock?"
"Um." Liu Fan nodded, then realized that he quickly glanced at the mobile phone, it was ten fifteen, "It's so late, but I haven't talked about the next point of knowledge."
凡 Liu Fan frowned. He was really anxious. After all, today, he had only two days to review.
Liu Wei closed the notebook and pushed it in front of Liu Fan. "So, if you feel the same, you will continue to come here tomorrow. I am sure I can tell you the next thing in a day. If it feels twisted, I'm going to the office tomorrow. You come to the office to find me. "
"No change, what's so easy to change." Liu Fan thought without thinking.
威 Liu Wei looked at Liu Fan and smiled meaningfully, "Isn't you uncomfortable at first?"
"In the beginning, uh ..." Liu Fan smiled embarrassedly. "Mr. Liu, please make your decision. I can do everything tomorrow, but I am sorry to affect your business."
凡 Liu Fan is telling the truth. He just reacted that he might take up two days with his teacher, that is, two days to make money.
"If you're really embarrassed, bring more classmates to come and eat with me in the future." Liu Wei naturally gave Liu Fan a step.
凡 Liu Fan smiled, and immediately asked the doubts in his heart, "Yes, Teacher Liu, why did you open a restaurant?"
"What's the reason for this, people must not have a job while alive." Liu Wei drank his beer and said ~ EbookFREE.me ~ Liu Fan became more confused and continued to ask, "Are you not a university teacher, isn't it work? ... "
"Ah, that's a joke from the university teacher." Liu Wei's words just changed, and his look changed. He seemed to realize that he was in a bad state in front of the students. The restaurant is the main business for me. Hahaha. "
Liu Fan is a sensitive person. The change of Liu Wei's expression just now is naturally in his eyes. Moreover, Liu Wei's words are clear and clear. It is impossible for Liu Fan not to hear, but he is only a student. Liu Fan is not qualified to go. Regarding the inner thoughts of the teacher, she followed the costume stupidly, "Mr. Liu, don't say that, you are better at cooking than teaching. It is delicious."
"Smelly boy!" Liu Wei pointed to Liu Fan and looked at the time again. "Okay, I will go back to rest earlier today. I ca n’t drive you after drinking, so be careful on your way."
"Okay, I can walk back quickly." Liu Fan stuffed everything back into his schoolbag, and said sincerely, "I really thank Teacher Liu today."
"Okay, let's go." Liu Wei waved as he drank. "My store opens at six in the morning. You can come at any time."
"Okay, goodbye Teacher Liu, goodbye Master."
I waited for Liu Fan to leave, Liu Wei's wife came to his side, holding her husband's shoulders with both hands, "Happy today?"
"Cut." Liu Wei touched his wife's hand. "It's just a stinky boy holding a Buddha leg temporarily before the exam."
My wife patted Liu Wei's shoulder without making any extra comments, but quietly began to clean up the table.
Liu Wei took out a cigarette and looked at the dark university outside the store through the smoke. He said to himself, "It's dark ... how can there be a sun ..."
