"Wow, that's amazing!"

"Our ancestors in China are really suffering!"

"But what does this have to do with Chinese medicine?"

"yes, this isn't a history lecture?"

"It matters!" Du Lin heard the questioning voice below, "Many theories of Chinese medicine are based on the October solar calendar, and in the eyes of many old Chinese medicine practitioners, there are actually five seasons in a year. ”

After saying that, Duhrin wrote "Spring, Summer, Long Summer (Season Summer), Autumn, and Winter" on the blackboard.

These are the five seasons in the October solar calendar. Obviously, it has one more 'long summer' than our current season, also called 'season summer', and these five seasons correspond to the five elements of 'wood, fire, earth, gold and water'. ”

"In spring, everything grows, plants and trees grow, and it belongs to wood in the five elements, who can tell me that this characteristic is similar to that organ of the five organs?" Du Lin seemed to like to interact with the audience.

"I know, it's the liver, we've just learned, the liver is the main drain and germination. One student raised his hand and replied.

"Very good! This student must be a good student who listens carefully. Du Lin praised the student, and then continued: "Then there is summer, the summer is hot, everything grows vigorously, the five elements belong to fire, what about the corresponding organs?"

This time, everyone didn't raise their hands, and those who knew shouted directly: "Heart!"

"That's right, the heart, also known as the yang organs, the five elements belong to fire, the fire is bright, the candle illuminates all things, the blood of the whole body is warm, the spirit is excited, and the vitality is endless. In terms of time, I directly wrote down the relationship between the five seasons and the five elements and the five organs, and everyone can understand it for themselves. ”

After speaking, Du Lin added to the previous board book: "Spring-wood-liver, summer-fire-heart, long summer-earth-spleen, autumn-gold-lung, winter-water-kidney".

"Traditional Chinese medicine advocates that the liver is nourished in spring, the heart is nourished in summer, the spleen is nourished in summer, the lungs are nourished in autumn, and the kidneys are nourished in winter. ”

After saying that, Durin drew two large circles on the blackboard, and divided each circle into twelve parts according to the scale of the watch.

"There is another number, that is, '24', a day is divided into 24 hours, and a year is divided into 24 solar terms, so is there a one-to-one correspondence between the two of them? The answer is, yes! 24 solar terms also correspond to 24 hours, and the night from 0:00 to 1:00 corresponds to the winter solstice, that is, the day with the shortest day and the longest night in the year, and 12 o'clock at noon corresponds to the summer solstice, and the 24 solar terms are arranged in turn. ”

After speaking, Du Lin wrote down the twenty-four solar terms in the two circles on the blackboard.

"How long do we generally advocate for an adult to sleep at night?"

"Eight hours!"

"What do you think is the best eight hours for sleep?"

The audience thought about it for a while, and some students still wanted to find the answer in the two circles on the blackboard.

A boy raised his hand and said, "I think it's appropriate to wake up at 7 a.m. and go to bed at 11 p.m." ”

"Tell me why. Instead of rushing to give the correct answer, Doolin let the classmate fully express his opinion.

"Seven o'clock in the morning in this circle represents 'Qingming', at this time, getting up, should make people refreshed, we have classes at half past eight every day, get up at seven o'clock in the morning, wash up and then go to breakfast, and then go to the teaching building, exactly half past eight. I think that since the school has set us to start classes at half past eight, there must be some reason, and it should be to encourage us to get up early. ”

"In your eyes, getting up at seven is 'getting up early'?" Durin was a little speechless.

The boy scratched his head embarrassedly, "For me, it's an early morning." ”

"Then I ask you, what time does your dormitory open in the morning?" asked Durin.

"Uh...... This ......" he hurriedly asked the classmate next to him, "What time does it open in the morning?"

But it seems that the classmates next to him don't know either.

"As a senior brother, let me tell you what time our school's dormitory opens, half past five! What is the solar term in this picture?"

"Sting!"

"Yes, five o'clock in the morning to six o'clock in the morning corresponds to the sting, sting is the meaning of hibernation, referring to the small insects hibernating in the soil, the stinging season, the spring thunder suddenly moves, wakes up the dormant insects. The bugs are awake, but you're not awake?"

The audience was laughing again.

"So the most suitable time to sleep is from 9 o'clock in the evening to 5 o'clock the next morning, why 9 o'clock? 9 o'clock in the evening corresponds to the solar term of the beginning of winter, winter, so it is time to hibernate. ”

Du Lin's humorous tone caused another burst of laughter from the audience.

"That classmate's idea just now also makes sense, the school starts at half past eight, there must be a reason for the class at half past eight, but why do I get up at half past five?" Du Lin paused, giving the students a time to think, "Go to morning exercises, get up at five o'clock in the morning, wash your face, brush your teeth, get dressed, the dormitory opens at half past five, go out for morning exercises." Don't care what you practice, whether it's running, doing exercises, practicing for an hour, coming back to take a shower, changing your clothes, and then going to eat and class, this is the real intention of the school to open the dormitory door at half past five, but to go to class at half past eight, students!"

"Oh~~~ So that's the case!" The hundreds of students in the audience suddenly realized.

"Of the numbers I just mentioned, the most magical number is actually 5. In the "Historical Records", it is said, 'There are five stars in the sky, and there are five elements in the earth'. Under the five elements, there are also five seasons, five senses, five viscera, five intestines, five bodies, five colors, five directions, five flavors, five smells, five aspirations, and five constants. Each one corresponds to the five elements one by one, as a traditional Chinese medicine, we must always keep this 'five' character in mind and fall on the prescription. For example, if a patient has stagnation of liver qi, pain in both flanks, and abdominal distention, you should prescribe him a soup of soothing the liver and regulating qi, green orange leaves, green peel, tangerine peel, citrus aurantium, magnolia bark, incense, Su stem, red peony, white peony, bupleurum, tulip, licorice. In addition to paying attention to the female patients in addition to the addition of half of the tulip, but also to consider the season, spring and summer breath upward, when taking this medicine, Su stalk rises, can be reduced, autumn and winter breath convergence, citrus aurantium decrease, also to reduce, long summer is suitable for tonifying the spleen, can be added to this recipe Poria cocos and sand kernels, spleen and digestion, in order to reduce the burden of liver and gallbladder burden. ”

"Wow~ There are so many exquisiteness?" The students in the audience were completely immersed in the breadth and profundity of Chinese medicine and couldn't extricate themselves, and even many students who studied Western medicine have begun to regret their chosen major.

"Lao Wang, thank you for helping me invite Xiao Du back. Zhang Guanshan, the dean of the College of Traditional Chinese Medicine, patted Professor Wang's shoulder, "At the beginning, when Xiao Du graduated, I hadn't come to be the dean, if I was the dean at that time, I would have to keep this child in school to teach, he is not only a genius in Chinese medicine, but also a genius as a teacher!"

"Dean Zhang doesn't have to regret it, I guess even if you are here at that time, it will be in vain. The year he graduated, not to mention the dean, the principal almost came forward to ask him to stay in school, but this kid just didn't agree, so he took his graduation certificate and left. Professor Wang said angrily and funny.

At this moment, the door of the Xinglin pulpit was pushed open by Hula, and several students who were standing behind the door to listen to the lecture were almost slapped on the wall, and a boy scolded on the spot: "I'm X, who is this XX?
