I have to say that Shen Yiyi actually pointed out a common problem of domestic scholars who have studied economics for a long time. They have always been porters of foreign theories, and have never lacked creativity themselves. Of course, it's no wonder they. People with a good foundation in mathematics have long chosen other science and engineering majors in the previous atmosphere of "learning mathematics, physics and chemistry well, and not being afraid to go all over the world" in China. Students who enter the economics department naturally have weaker mathematical intuition or feelings than other disciplines. It is precisely for this reason that domestic economic papers tend to emphasize exposition and ignore reasoning, and the distance between the level and the advanced in the world is not one or two points.

As a leader in the research of domestic economics, the old professor is naturally not ignorant of such a reality. It's just that the general environment is like this, and it is not something that he can change alone. Despite this, today, when a high school student who had never known anything in his life pointed out to his face, the old professor still felt a little ashamed in his heart. However, Shen Yiyi not only pointed out the shortcomings and problems to him just now, but also reminded him of the solution. Yes, since the economics major has a low level of mathematics, why not unite with the mathematics department? With the mathematical skills of the Department of Mathematics and the proficiency of mathematical tools, coupled with my familiarity with economic theories for many years, if the two sides can study together, it may not be as good as other well-known economists in the world. What's more, the old professor also knows that the Department of Mathematics is now also the Qingshui Yamen, and the annual teaching funds received are much less than those of his own Economics Department. If you can allocate a little research funding to them, you must also solve their problems.

The more I thought about it, the more I felt that this idea was a good idea, and the more I looked at Shen Yiyi, the more satisfied I became. This little girl is really not simple! There are actually many people who can see the problem, but the aspect of finding the problem is more important than finding the problem and proposing a solution to the problem. And for a little girl who is just a high school student, whether it is to find a problem or solve a problem. This girl all shows what makes her different. These uniqueness made the old professor want to recruit Shen Yiyi to him even more.

So, before the train entered the platform of Beijing Railway Station, the old professor did his best to understand Shen Yiyi's situation. Helplessly, Shen Yiyi himself was strictly guarded, but he didn't tell him where he came from. The back and forth between the old and the young finally ended with the teachers and students having to get off the train and leave because the train arrived.

Finally managed to get the pedestrian off the train at the moment when the train restarted. I was finally relieved. Seeing her relaxed appearance, Peng Weining, who had been observing her, couldn't help but feel funny. In fact, he didn't know what Shen Dao was for, and he refused to tell the other party his identity. In his opinion, it would have been an honorable thing to be able to talk about college students and even their teachers a little bit too much to talk about as a high school student. If this is to let the other party know his origin, it will not be a big deal for Shen Yiyi. He had vaguely heard that Shen Yiyi had politely rejected the special recruitment of Tsinghua University and Jiaotong University and other famous domestic schools. There is such a precedent, even if Peking University wants to recruit her this time, she can completely refuse. So he really didn't understand Shen Yiyi's behavior of completely concealing his origin. However, Peng Weining is very clear about his positioning. Before leaving the army, his mother told herself on the phone that she wanted to take care of Shen Yiyi one by one and not let anything go wrong. So naturally he won't say what he thinks in his heart directly. On the contrary, seeing that Shen Yiyi seemed to have been asked too much just now, and he looked a little thirsty when he spoke, Peng Weining took out the fruit treasure that had just been put aside and handed it over.

"Oh, here you go. I forgot to drink water when I spoke, and now I'm thirsty, right? ”

Shen Yiyi really talked a lot just now, and now he is a little dehydrated. So I saw the cup handed over by Peng Weining. Without thinking about it, he picked it up and poured it into his mouth.

Until all the glasses of water are drunk. She still felt that she couldn't quench her thirst, so she stretched out the cup to Peng Weining again, meaning another cup.

There is no need for Shen Yiyi to say anything, Peng Weining already understands it. He took the cup, took out the fruit treasure again, and got her a spoonful. He got up again and walked towards the boiling water stove.

Looking at Peng Weining's back, which can be said to be a "seductive crime", Shen Yiyi admired it with a look that was incommensurate with her identity at the moment, and thought to herself that Luo Qiong was still quite reluctant to look at Peng Weining when she got out of the car. Although the income of being a soldier is not high, and he can't take care of his family in normal times, he is a handsome guy. It's eye-catching! And the physical fitness is good, isn't it?

Fortunately, Peng Weining didn't know what thoughts were turning in her heart, otherwise she would have to be angry with her.

Shen Yiyi is now enjoying the treatment of being "served" by Peng Weining with peace of mind. Anyway, aren't they called "brother and sister" now, and it's natural for the younger sister to be taken care of by the elder brother.

Taking advantage of the fact that there was no one in the lower bunk at this time, Shen Yiyi saw the conductor coming over to inspect and hurriedly asked her to change to the lower bunk. The conductor still looked at the 200 yuan that the little girl took out with some surprise, saying that it was used to make up for the difference in the price of the bunk. However, since the other party is so familiar with the rules and regulations of the railway, and more importantly, since he has the money to make up the difference, of course he has no reason to disagree. Therefore, when Peng Weining came back after others had finished fetching water, he found that he and Shen Yiyi could already sleep in the lower bunk.

In this regard, Peng Weining was not frightened by Shen Yiyi's ability to move. A little girl who can lead a group of classmates to make special equipment that everyone in the military region wants, you really can't underestimate her. What's more, people who have been on the train know that the most comfortable bunk is the lower bunk, and people can sit up straight and things can be seen. He also knew that Shen Yiyi was actually a little rich woman, and it was estimated that her income was much more than the allowance she had received over the years in the army.

Shen Yiyi was in a hurry, and replaced the bunks of the two with lower bunks, and she ignored an important issue. If both of them slept in the lower bunk, wouldn't it be that in this compartment, wouldn't it become that she and Peng Weining often had to lie facing each other? There are still thousands of kilometers from Beijing to Guangzhou, how embarrassing it will be along the way! This problem, the two of them didn't think of it at this time, and it wasn't until they turned off the lights and went to bed that they found that the two had to have a little "little ambiguity".

That's how it is on the train, someone gets off the train, someone must get on. Since Shen Yiyi had already given the money to the two lower bunks in this compartment, it was natural that the middle and upper bunks that she and Peng Weining had originally had were vacant at this moment. Of course, the flight attendants will not let go of these empty berks. So along the way, soon, some people occupied these empty shops.

Shen Yiyi also talked a lot with the people from the economics investigation team of the highest universities at the beginning, but at this time, he was obviously in poor spirits, a little atrophied, and he didn't like to talk much when he leaned on the carriage. Peng Weining saw that she seemed to be a little tired, so he stopped bothering her, went to the dining car by himself, and came back with two meals.

It was just meal time, and Shen Yiyi was thinking about his thoughts with his eyes closed, when he suddenly smelled the fragrance of food in his nose. When she opened her eyes, she saw that Peng Xiaohandsome was holding a lunch box in front of her. Seeing that she opened her eyes, Peng Weining handed her a pair of chopsticks.

"I've worked hard for you today, I've talked too much, I'm tired. Eat, sleep well after eating, and when you wake up, you will almost arrive in Guangzhou. ”

When Shen Yiyi heard what he said, he always felt that he was a little sarcastic. How can anyone talk about being tired? But looking at his serious face, I can't blame him. Because I'm really tired of talking. Therefore, Shen Yiyi didn't bother to protest with him, took the lunch box and chopsticks he handed over, and began to eat.

The level of food on the train cannot be expected too high. Anyway, the train meal in the mainland is just to keep you from starving. As for how delicious it is, passengers don't have such unrealistic fantasies. It was not until the ice was broken that the tension between the two sides of the strait broke and more mainland compatriots were fortunate enough to set foot on the treasure island that they had been separated for many years, that everyone realized that train meals could also be affordable and delicious. The impact of the Taiwan Railway Bento on the mainland's railway concept is still very great.

It's just that in this era, of course, the train meals in the impression of mainland passengers are just expensive and unpalatable. Fortunately, Shen Yiyi and Peng Weining were still able to complete this dinner quickly. One of them is a habit of eating quickly in the army, and the other is the reincarnation of a female man, who is not particular about eating, so although it is not delicious, the train meal that is satisfying will be enough.

After eating, Peng Weining put away Shen Yiyi's lunch box and put it together with his own. However, he didn't leave in a hurry after doing this, but told Shen Yiyi: "You should hurry up and finish washing up first." Don't wait until the lights go out, you'll have to wait a long time when you're huddled together. ”

Peng Weining completely regarded Shen Yiyi as a little girl who went out for the first time, and she took good care of her. But Shen Yiyi, who has rich experience in business trips, naturally understands it very well in his heart. Thanks to the kindness of others, Shen Yiyi naturally finished washing up quickly and fell asleep before the lights went out.

In the train broadcast, the train broadcast is still broadcasting in a style comparable to that of the Central People's Radio. Shen Yiyi listened to it without a match. Anyway, there is no switch to turn off the horn. So Shen Yiyi, who listened to the radio with his eyes closed, may have fallen asleep in the eyes of Peng Weining, who came back from taking out the garbage. He saw Shen Yiyi's exposed arms, reached out to help her put it away, and lifted the blanket up, but unexpectedly looked at Shen Yiyi who opened his eyes. (To be continued......)
