Now that he had decided to teach the students, Li Jingyuan had no choice but to prepare, because he had never stood on a big podium before, so he rarely felt a little nervous.

Li Jingyuan had no clue about preparing for classes, and in desperation, he had to learn from the process of those open courses on the Internet in later generations. After thinking about it, Li Jingyuan felt that he should prepare materials in two aspects. On the one hand, according to the needs of the ordinary class procedure, a more systematic explanation is prepared in advance, similar to an essay, and on the other hand, some materials are prepared to answer students' questions.

Because he was still unsure of what kind of level the students of the Faculty of Economics of Seoul National University were now, Lee Kyung-won had to painstakingly prepare a series of materials, from macroeconomic analysis to academic materials such as political economy, from finding a suitable small store to how to obtain the first pot of gold in the fastest way. Combined with the current national conditions of South Korea, Li Jingyuan finally completed his preparations.

Seeing the students sitting in the large classroom on the ladder, Li Jingyuan took a deep breath, strengthened his courage, and stepped onto the podium.

"Ahem, hello everyone, I'm today's lecturer, my name is Li Jingyuan, I guess everyone has asked me a lot about the past few days, hehe, I'm about the same age as you, so I hope everyone can relax during class, if I'm too nervous, I'll be a little embarrassed, and I still need to call you seniors according to age." So I decided that you should try to ignore my teacher, I should try to ignore our age difference, and let's talk about it as equals. Li Jingyuan's words made the students sitting below feel a lot more at ease, in this kind of big classroom, many students will be more afraid of the teacher's questioning, and the answer is fine, if the answer is not up or the answer is too outrageous, it will be more embarrassing, especially in South Korea, the teacher can punish the student in accordance with the law.

"Everyone should basically know the basic definition of economic principles, which are the scientific laws of economics that reflect the objective laws of economic development, which are composed of economic concepts, categories and category systems, including economic axioms and economic theorems. Among them, the axiom of economics is the starting point of the theorem of economics, and the theorem of economics is the result of the derivation of the axiom of economics. ”

"There are ten principles in economics: 1. People are faced with trade-offs, 2. The cost of something is something that is given up in order to get it, 3. Rational people consider marginal quantities, 4. People respond to incentives, 5. Trade makes everyone better, 6. Markets are often a good way to organize economic activity, 7. Governments can sometimes improve market outcomes, 8. A country's standard of living depends on its ability to produce goods and services, 9. Prices rise when governments issue too much money, 10. Society faces a short-term alternating relationship between inflation and unemployment. To be more specific, first principles, people face trade-offs......"

"So how do you apply these ten principles, I boil them down to three things: first, how people make decisions, second, how people influence each other, and third, how the economy as a whole works."

“……。 That's all for academic stuff for now, and now you can ask questions, you can ask academic questions that you don't understand, or you can ask specific case operations. Finally, after finishing the academic things in the prepared systematic textbooks, Li Jingyuan began his more confident Q&A session.

"Since you have so many questions, if I answer them all, there is obviously not enough time, so let's give you a few minutes, and everyone will write down the questions they want to ask on paper, and I will collect them later, and draw lots to answer them. Otherwise, if I name me, it's a bit unfair, it's okay to point to boys, but if you point to girls, you don't necessarily say anything about me. Li Jingyuan didn't have a teacher's frame at all, and made jokes directly in class.

"Hahaha." The effect of joking is still good, the atmosphere of the class is lively, and the students also begin to like the way of teaching Li Jingyuan, the little teacher. It's easy, easy to understand and stress-free, making it very comfortable to listen to.

"Let me see, what's the first question?" Pulling out a random piece of paper from the pile of notes that came up, Li Jingyuan began to look at it. ,

"Does Mr. Li have a girlfriend?" Reading out the words on the note, Li Jingyuan was full of black lines: "Okay, who wrote this, looking at the handwriting, it should be a girl, I said sister, this is class, you should give me this kind of note after class." But this is the first problem, and it's not good to pass directly, so I'll tell you, not for the time being. ”

"The second question is, I hope to start my own business after graduation, and I would like to ask Mr. Li to give me some advice. Well, that's not too far off-topic, okay, I'll try to answer that. For this student who wants to start his own business, first of all, I appreciate your courage, but I still have to express some worries. Starting a business is not a simple matter, even if it is not starting a business, even if it is just a small online store, there are many factors that need to be considered. This includes a survey of supply and demand, a reserve of your own personal capital, and your personal interests and so ......on. ”

"Huh~~~" After finally coping with this big lesson, Li Jingyuan was finally able to take a break. In an open class, except for the break in the middle, the first half of the theoretical lectures, the second half of the answering questions, Li Jingyuan sat on the stage for nearly 5 hours, although his physique is very good, but he has been stared at by so many people for 5 hours, and he still feels a little tired. Constantly sorting out ideas, teaching courses to students, and various strange questions that tested Li Jingyuan's brain power from time to time in the second half of the semester, Li Jingyuan's mental consumption was really a bit big.

"Jing Yuan, the class is very good." After the students left the classroom, Li Changmao came to Li Jingyuan's side and patted him on the shoulder.

"I don't know if it's okay or not, but nothing big went wrong." Thinking of the personal questions mixed in the notes handed over by the students just now, Li Jingyuan felt a little afraid.

"Hehe, this is you, a young man, who can get so close to the students, but our other teachers' classes are not so active. The students seem to have approved of you, and they may ask you to continue. ”

"No, I'm too tired this time, come again, do you want my life?" already felt a little like vomiting, and Li Jingyuan hurriedly refused.

"That's not something I can call the shots, the students' requests still have to be met, but we'll arrange less for you." Li Changmao smiled, but to Li Jingyuan, it looked like a demonic smile.

"Well, I'll go back and make some CDs, and I'll record them the way I would in an American college open class, and then you can use these things to send students away." I have a lot of other things to do, not only to go to the TV station to record a show, but also to go to school myself. ”

"That's fine, but you can't skip classes at all, otherwise, the students won't be satisfied, and according to the requirements, you have to take a big class like today at least twice a semester."

After weighing it, Li Jingyuan still agreed, if it was calculated like this, it would not matter much. Two big classes in a semester, that is, two days, is still quite easy: "Then today's class is not counted?" In other words, I just need to talk about it again this semester. ”

"You kid, you really don't want to suffer at all." Li Changmao pointed at Li Jingyuan and said with a smile while shaking his head.

"Hehe, I'm not a regular job anyway. If you don't have a salary, aren't you lazy if you can? Li Jingyuan muttered quietly.

"I'm willing to pay you a salary, do you dare to accept it?" was annoyed by Li Jingyuan's muttering, Li Changmao asked Li Jingyuan, there is a big situation that if you dare to collect money, I will dare to arrange classes for you.

"Don't, what kind of relationship do we have, and we have to raise money, it's too cheesy, Principal Li, if you pay me a salary, it will be too outlandish. That, you're busy first, I'm still a little ahead of schedule. Seeing that the signs were wrong, Li Jingyuan hurriedly took two steps and ran away.

After running out of this big classroom, Li Jingyuan's mood was much more relaxed, and the feeling of being in the spotlight on the podium just now was too stressful. This kind of pressure is completely different from stage performance, because it is a serious learning atmosphere, so the atmosphere is much more solemn.

"Taeyeon? Are the kids there? Finished practicing? Eun, come out then, OPPA will take you to dinner, even if it is to help me celebrate, OPPA has finally finished the lecture. "I called Taeyeon, and Lee Kyung-won wanted to call the girls out. As Li Jingyuan's favorite junior in the company, being called out to eat by him from time to time is relatively common for children when they are young.

Staying with these girls, Li Jingyuan always feels very happy, probably because his psychological age is not young, every time he sees the energetic performance of these girls, he himself feels energetic. Girls' Generation is also an outlier in South Korea, as the leader of a new generation of girl groups, their songs can relieve a lot of pressure on 30~40-year-old uncle fans, it is really a very energetic combination, Li Jingyuan is also made a lot of fun by these little girls.
