Fang Yan didn't say anything, but smiled and listened to Tan Qingyun.

"Since we have such a rare opportunity this time, I think Dr. Fang and I should tell our classmates something more practical."

Tan Qingyun said and looked at Fang Yan: "What does Doctor Fang think?" ”

"Professor Tan is a senior, and I am here to praise Professor Tan today." Fang Yan said with a smile.

"Since Dr. Fang doesn't have any opinions, it's so decided."

Saying that, Tan Qingyun spread his hands and said to the students: "Today, Doctor Fang and I didn't prepare for class, we improvized, the students came to solve the questions, and I and Doctor Fang came to discuss and solve the doubts, what do you think?" ”

"Professor Tan, what you said is true?"

"Professor Tan, really?"

The students were instantly excited.

The step-by-step class is the least favorite class of the students, and the class that everyone likes is the kind of interesting class.

For example, the Provincial University of Traditional Chinese Medicine basically invites many well-known professors and chief physicians of famous tertiary hospitals to give lectures in the hospital every year.

But why is there so little overcrowding?

It is precisely because many professors or directors are famous, but the lectures are not interesting, and the people who listen to them are drowsy.

Most of the people who are really willing to listen to the lectures are top students, some want to make a good impression in front of the professor and director, and some do understand something, but for most students, it is better to read a book.

This time, the reason why there were so many students was precisely because Fang Yan's lectures were interesting and most people liked to listen to them.

Now when I heard Tan Qingyun say that everyone should ask questions, the interest of the students was immediately aroused.

That's interesting.

"Doctor Fang doesn't have any opinions, right?" Tan Qingyun asked Fang Yan again.

"I can do it all." Fang Yan said with a smile.

"Okay, then follow this pattern."

Tan Qingyun said with a smile: "You can raise your hand to ask questions, the opportunity is rare, don't waste the opportunity, think carefully when asking questions, and it is best to ask some good questions." ”

Tan Qingyun is obviously afraid that the questions raised by the students are simple and meaningless.

In fact, in Tan Qingyun's view, in terms of the level of these college students, there are no too difficult questions, and it is mainly up to him to extend.

Therefore, what Tan Qingyun likes more is the kind of problem with a wide scope.

After all, Tan Qingyun asked himself that he was very knowledgeable, and in terms of knowledge reserve and knowledge accumulation, it was definitely not comparable to Fang Yan.

"Students can listen and think at the same time."

Tan Qingyun smiled and said, "I'll raise the first question. ”

Saying that, Tan Qingyun looked at Fang Yan with a smile again: "Doctor Fang, the first topic we discussed, let's talk about yin and yang first, as the saying goes, yin and yang are all in one condition." ”

Lu Fengmin frowned slightly, he could see that Tan Qingyun was prepared.

"Tan Qingyun is planning to bully Doctor Fang's youth."

In the last row of the classroom, Huang Zhengliang, Lin Jiangyu, and Xu Jinliang were talking in a low voice.

Knowing that Fang Yan was coming over here today, Huang Zhengliang and Lin Jiangyu deliberately took time out to come over, and Jiang Meng and Jiang Weixue were on duty on the medical team.

It's just a two-hour class, but it doesn't affect anything.

A few people were mainly a little curious, Tan Qingyun, is there any purpose for this?

Now it seems that Tan Qingyun really didn't hold back any good fart.

"Tan Qingyun is planning to make a name for himself through Doctor Fang." Xu Jinliang said in a low voice.

Although Tan Qingyun is already quite famous, from the whole country, Tan Qingyun's fame is greater than Fang Yan's, but being able to step on Fang Yan will also increase Tan Qingyun's fame.

After all, Fang Yan is the latest rising star in Gyeongju Province, and he is in the limelight, if he can overpower Fang Yan, the more famous Fang Yan will be in the future, the more benefits he will bring to Tan Qingyun.

There will always be people who will talk about it.

"It's a pity that Tan Qingyun's confidant doesn't know who he is." Huang Zhengliang said with a smile.

Yin and yang, this is a big proposition, as Tan Qingyun said, there is a saying in traditional Chinese medicine that yin and yang are adjusted to eliminate all diseases, and the root of all diseases is the imbalance of yin and yang.

But this topic is wide, and there are many knowledge points involved, and the more knowledgeable people are, the more they can talk about this topic well.

Like some young doctors, even if they understand it in their hearts, if they really want to say it, they may not be able to explain it.

"In that case, let me say a few words first?" Tan Qingyun politely asked for Fang Yan's opinion.

"Professor Tan will speak first." Fang Yan said with a smile.

Tan Qingyun smiled and said: "I said just now, there is a saying in Chinese medicine that yin and yang are adjusted and all diseases are eliminated, and the root of Chinese medicine treatment is to regulate yin and yang. ”

"Our sages put forward the theory of yin and yang, which was originally used to represent the unity of opposites in pairs and opposites, which is actually the earliest concept of relativity."

"Yin is cold, dark, gathering, and materialization, and yang is heat, light, transformation, and gasification........"

Tan Qingyun said: "If you want to understand yin and yang, you must first understand the characteristics of yin and yang, within a relative range, in line with the characteristics of yin, it belongs to yin, and in line with the characteristics of yang, it belongs to yang, "Neijing" has said that 'the foundation of life, based on yin and yang'......"

"And life is a balance composed of two contradictory energies of yin and yang, in this balance body, the positive pole is yang, the negative pole is yin, the balance of yin and yang has people, life is decreasing, the sky is yang above, the earth is yin below, people are in the middle, and the main thing is the balance of yin and yang........"

"We study traditional Chinese medicine, the surface and the inside, cold and heat, virtual and real in Chinese medicine are a group of opposing and unified positive and negative phenomena manifested in the process of disease, that is, yin and yang, from the meaning of positive and negative opposites, the appearance, heat and empirical evidence belong to the category of yang, and the inside syndrome, cold syndrome, and deficiency syndrome belong to the category of yin syndrome, so all diseases can be classified into two categories: yin pattern and yang pattern.......

Tan Qingyun talked eloquently.

"Tan Qingyun deserves such a big reputation, he does have a level ......."

Huang Zhengliang said: "From the classification of yin and yang, Tan Qingyun can be said to be very clear about the occurrence and development of diseases.......

"In fact, to learn Chinese medicine, you must first understand the five elements of yin and yang, only by understanding the five elements of yin and yang, can you be considered to be introductory, Tan Qingyun's explanation is easy to understand, and the yin and yang are very clear."

Lin Jiangyu also said.

Excluding Tan Qingyun's character, Tan Qingyun's level is really good.

Without lesson preparation, improvisation, talking about yin and yang, reasonable, and logical, this alone is not easy.

There are some things, like Lin Jiangyu and others also know, but they can improvise, and they may not be as good as Tan Qingyun said.

"In this delicate balance, life can continue, and when the balance is broken, it is sick, and at this time we must distinguish yin and yang, so as to find the corresponding way......."

After talking for a while, Tan Qingyun stopped and said with a smile: "I'll just say so much first, and then let Dr. Fang also tell you about it." ”

Saying that, Tan Qingyun also glanced at Fang Yan with a smile, he had basically talked about the basics of what he could talk about just now, and now that Fang Yan talked about it again, it would be much more difficult.

"Tan Qingyun took the lead, he threw out the proposition himself, he spoke first, and Dr. Fang picked up the leftovers, which is really a good calculation." Huang Zhengliang is already a little disdainful of Tan Qingyun.

It is said that with Tan Qingyun's age, how can he let Fang Yan and let Fang Yan speak first.

"Professor Tan talked a lot just now, and he said it very well,"

Fang Yan said with a smile: "The basis of yin and yang, the distinction between yin and yang, the relationship between yin and yang and traditional Chinese medicine, the relationship with diseases, and so on. ”

Fang Yan paused as he spoke, and continued: "Everyone knows that Taoists say that the Tao gives birth to one, and one life gives birth to two, this two, two gives birth to three, and three gives birth to all things, and two is actually yin and yang.......

Speaking of this, Fang Yan paused again and said: "Speaking of Taoism, I think of a myth and legend, all students know that Pangu opened the world and Nuwa created people to make up for the sky. ”

The classmates nodded one after another, there is almost nothing that the Chinese people do not know about this myth and legend.

Fang Yan continued: "It is said that the Pangu God was born from chaos, holding an axe to open the sky, cutting through the chaos, opening the heavens and the earth, the light one floats up for the sky, and the turbid one sinks for the earth, and the Pangu God steps on the earth, holds the sky with his hands, and is in the center, in fact, this is what we often call the three talents of heaven, earth and man. ”

"The sky is yang, the status is yin, and people are in the middle, and the god Pangu in order to prevent the sky from tilting, he bears the sky with his body, and finally incarnates mountains, rivers and lakes, and eyes the sun, moon and stars........"

Speaking of this, Fang Yan asked the students with a smile: "What did you think of from this story?" ”

Without waiting for the students to answer, Fang Yan continued: "Although this story is a mythical story, it is also a process in which the Tao gives birth to one, life to two, two to three, and three to all things. ”

"From this story, we can understand that yin and yang are one and can be transformed into each other, yin and yang are opposite, they are mutually restricted, and yin and yang have their ups and downs and balances."

Fang Yan said: "At the same time, at any time, yin and yang will always follow their own characteristics, just like Pangu opens the sky, floating and clear, sinking and turbid, if you observe carefully, you will find that people are actually a heaven and earth, the mind is clear, and the filth goes down, once this law is broken, there will be a tilt of heaven and earth, and yin and yang are reversed......."

"If we use the upper focus, the middle focus, and the lower focus, then the upper focus is the sky, the middle focus is the people, and the lower focus is the earth......."

Fang Yan said with a smile: "The overall view is three focal points, and the chest above the diaphragm is the upper focus, including the heart and lungs, head and face; The middle focus is from below the diaphragm to the umbilicus, including the spleen, stomach, and below the umbilicus to the second yin, including the liver and kidney, large and small intestines, and bladder. ”

"I'll go."

Some classmates couldn't help but stand up: "Senior Fang Yan, in this way, Zhongjiao is like the Pangu god who supports the sky, providing nutrients and energy, and at the same time transforming and transporting, reaching Zhongjiao, and excreting in Xiajiao....... Just form a loop. ”
