On May 20th, a cloudy day, in the morning, at Yenching University, when the class bell rang, Ouyang Yun walked into the easternmost classroom on the second floor of the teaching building with a military uniform and handouts. Behind him, followed Chu Tiange, who was also dressed in military uniform.

Wearing a military uniform to class was Gu Lianyun's idea, thinking that this would make him look more fierce and help deter students. Ouyang Yun didn't really want to rely on military uniforms, but the first time he went to the podium, he really didn't know the bottom in his heart, so he did it.

The classroom was bustling with students, many of whom were adding seats, and even Chu Tiange had to find a seat behind the most sparse and sat down. As the class leader Fan Wei shouted "stand up" loudly, the students stood up and bowed deeply to Ouyang Yunshen who walked onto the podium.

Ouyang Yun returned a military salute with a smile, and said with a smile: "Everyone please take a seat." When everyone sat down, their eyes swept over everyone's faces, and when they saw Pan Meiren and Chen Jiayao, they nodded lightly without a trace, and then said: "I'll introduce myself first, the contemptible person has the surname Ouyang, and the single name is a cloud word, no word." Pick up the chalk, write your name on the blackboard, look at it after writing, turn around and say: "I haven't practiced chalk writing, it's ugly, students, please don't laugh." ”

"Poof!" It's good that he didn't say this, but when he said it, some people couldn't help laughing.

Ouyang Yun didn't care either, picked up the roster and looked at it, and said, "There are a total of thirty-five people on the roll call, there are no less than fifty students sitting here, so let's go to class directly." ”

Putting down the roster, opening the handout, turning around and writing "modern medicine" on the blackboard, Ouyang Yun said eloquently: "Regarding the definition, origin and development of medicine, I think you should be very clear, then, we will focus on modern medicine in the future."

The history of medicine has a long history, such as traditional Chinese medicine in China, the development and continuation of traditional Chinese medicine can be said to be a miracle, so many ancient human civilizations around the world, such as ancient Egypt and ancient India, they have all created brilliant medicine, but only Chinese medicine has really been handed down - and the concept of modern medicine has only begun to appear in recent centuries and developed from ancient Greek medicine, and Chinese medicine also plays an important role in it and has a profound impact on the pharmacology of modern medicine - "Speaking of this, He paused for a moment, paid attention to the students' reactions, and asked: "Looking at everyone's expressions, everyone seems to have a lot of questions about my positioning on the relationship between Chinese medicine and modern medicine, this issue will be discussed in the next class, and then we will talk about ancient Greek medicine, ancient Greek medicine has had a great influence on later generations, in a certain sense, Roman medicine and medieval Arab medicine are its continuation." The ancient Greek school represented by Hippocrates abandoned theological explanations and sought to find the cause of disease in nature and the human body, emphasizing clinical observation, advocating prevention, and emphasizing measures that would help the body heal naturally. These ideas are an important historical source of modern clinical medicine, and some of the ethical principles set forth in the Hippocratic Oath are still held by doctors today......

"Let's talk about modern medicine ......"

Ouyang Yun had no experience as a teacher, and his first lecture seemed unremarkable, but fortunately, the things he prepared were novel enough to satisfy the students' curiosity and somewhat make up for the lack in this regard. When the bell rang for class, he breathed a sigh of relief, saying that he didn't expect to be a teacher so hard, his throat was so dry that it was about to smoke, and he quickly said, "That's all for today, students, see you again!" "As soon as the handouts are collected, prepare to flash people.

However, the students didn't let him go, and after everyone bowed under the leadership of Fan Wei, they didn't know who shouted first: "Professor Ouyang, sing a song?!" ”

"Sing!" He was getting off the podium, and when he heard this proposal, he stumbled under his feet, and almost fell, and secretly said that this voice is still singing, and if he sings again, he will catch fire. Arching his hand to everyone, he said, "Next time," pointing his finger to his throat.

At this time, Pan Meiren blushed, squeezed out of the crowd with a thermos teacup, didn't dare to look at his face, and whispered: "Professor, you drink tea to moisten your throat." ”

The beauty is courteous, and it is the kind that has a lot of feelings, Ouyang Yun naturally smiled, thanked him, took the teacup and drank a small sip, saw that the tea was warm, drank two more sips, returned it to her, thanked her again, and was about to leave, but several girls blocked the door.

He wanted to find Chu Tiange to solve the siege, but this one was good, standing with Chen Jiayao, he had completely forgotten his identity as a teaching assistant, and coaxed in it: "I can prove that the professor's singing is indeed not bad!" ”

"Just sing "On the Water Side"!"

Ouyang Yun was surprised, and said in his heart that even "On the Water Side" knew the truth, and couldn't help but look at Pan Meiren, who blushed to the base of his neck, looked at him timidly, and quickly lowered his head.

Ouyang Yun didn't mean to blame her, and even felt a little happy - Pan Meiren gave him a really good feeling, maybe because this kind of girl didn't exist in the twenty-first century, so her shyness fell in her eyes, which was particularly moving. If she can tell her best friend what happened in the hospital, does that mean that she is interested in him? He smiled and said, "Then sing one, the song is called "My Chinese Heart". ”

The students applauded.

Ouyang Yun smoothed his throat with his hand and sang: "Rivers and mountains are only in my dreams, and the motherland has not been close for many years, but no matter what, it can't change my Chinese heart."

Although I wear a dress, my heart is still Chinese, and my ancestors have already branded everything I have with a Chinese seal.

The Yangtze River, the Great Wall, the Yellow Mountain, and the Yellow River weigh a thousand pounds in my chest.

No matter when, no matter where, the heart is the same.

The blood flowing in my heart, surging with the voice of China, even if I was born in another country, it can't change my Chinese heart. ”

After the singing, the students were still immersed in it, and many of them were clearly deeply moved by the tears on their faces. The corridor was also crowded with students at this time, obviously attracted by the singing, and I don't know who applauded first, and then, a wave of applause broke out inside and outside the classroom. Everyone applauded and shouted, "Sing so well, let's do it again!" ”

When Ouyang Yun was a special soldier, his few pastimes were karaoke and drinking and eating, and after a long time of exercise, his voice was still so-so. He originally just wanted to sing casually, but the song "My Chinese Heart" was written so well, singing and singing, he naturally thought of reality, and his feelings gradually became sincere, and even he was moved. He can't sing the song anymore, but he has something to say in his throat and doesn't vomit unpleasantly, he took advantage of the topic and said: "The song is not sung, although the song can also inspire people, but it can't solve any practical problems." Do you know the truth? What I'd like to do now is to be able to answer your questions, but unfortunately none of you asked. Did you understand what I just said? Or do you not have a little opinion of your own? Knowledge, there is doubt before you ask, and only when you ask can you go into school. I'm actually quite scared about this professorship, and the reason why I have to muster up the courage to stand here is that I hope to be able to throw bricks and stones, so that one or two real professors can appear among you, because our country really needs it. How many people are there in the country? Forty thousand, how many children are there? There's always 50 million, right? However, how many schools and how many universities are there in the country? How many experts and professors in the university can be compared to Ximei? Take penicillin, for example, the Englishman Alexander? Fleming discovered this microorganism, but what about us Chinese? I'm afraid most people don't even know what a microbes are. I admit that China has four great inventions that we are proud of, the compass, gunpowder, movable type printing and papermaking, which are all great inventions, but this only proves the wisdom of our ancestors, and today's history is created by us people......"

The class bell rang, Ouyang Yun realized that he was a little overdone, he squeezed out of the classroom with the handouts, and when he saw Gu Jiegang at the end of the crowd in the corridor, he couldn't help but feel very embarrassed, and hurriedly smiled at him and said, "Professor Gu, I'm sorry, I forgot the time." ”

Gu Jiegang smiled and said, "It's nothing, you spoke very well, and I also benefited a lot from listening to it." ”

This is a real master, Ouyang Yun, a plagiarist, naturally didn't dare to compare with him, and he didn't even dare to say it, so he sincerely apologized again, and then walked downstairs with Chu Tiange.

As soon as they walked out of the teaching building, Situ Leiden greeted them and said with a smile: "Mr. Ouyang seems to be very popular with the students, but now I think that you only have two classes a week, which is too little." ”

Ouyang Yun hurriedly waved his hand and said, "Headmaster, don't be kidding, at this level of the kid, it is already difficult to cope with two classes, and if you increase it any more, I am afraid that it will be ugly." ”

Situ smiled, handed him a letter and said, "This is a letter from Harvard University President Conant asking me to pass it on to you, and he hopes that you will visit Harvard if it is convenient for you - Mr. Ouyang, you won't mind if I send your paper to President Conant for proofreading, right?" ”

Ouyang Yun smiled and didn't say anything, in his opinion, this was a good thing, which was invisibly equivalent to helping "penicillin" advertise - the paper only mentioned some superficial things, and he did not write down the key techniques of mass production.

As an old private university in the United States, Harvard University enjoys a considerable reputation in the United States, and has produced many presidents, and even has the saying that "there is Harvard first and then there is the United States", which can be invited to visit by Harvard University, which is what an honor in Situ Leiden's opinion, but Ouyang Yun's reaction made him feel a little incredible, this young man didn't even rush to open the letter, just said thank you to him, said I would consider it, and then said goodbye to him and left directly.

This Ouyang Yun has spent time in the United States, so he won't know about Harvard, right? Looking at his tall back, Situ couldn't help but wonder.
