Walking on the street, Gu Fan smoked a cigarette while looking at the complexions of the people around him, and deduced in his heart whether they were sick, what kind of disease they had, and how to treat it.

When he was a child, Gu Zheng took Gu Fan to wander aimlessly around the township, often asking him if the oncoming people had hidden diseases and how to treat them. Gu Fan, who came and went, also developed this habit of recognizing people's faces and judging people's illnesses.

"You'll never meet as many patients in the clinic as you see, but nine times out of ten. It's just that this disease is severe or mild, some have already manifested, some are still in the incubation period or a slight discomfort will not affect the normal life of the person, only a long time of observation and accumulation of experience can you fully grasp the word. When he was a child, Gu Fan often heard his grandfather teach him like this, which made him develop the habit of looking at people's faces and walking posture in his spare time.

"The most basic thing in Chinese medicine is to see, hear, ask, and cut, and the word formula is the most basic foundation of the four. Gu Fan, it's very simple to be a Chinese medicine doctor, but it's difficult to be a good Chinese medicine doctor, you need to keep learning and accumulate experience, there are not many patients in the hospital, but there are many in the society, study hard" Gu Fan has never forgotten Gu Zheng's words, because he knows that learning can better accumulate experience.

Gu Fan walked on the street and looked at all kinds of people, constantly analyzing their physical conditions in his mind, and giving a medicine suitable for their identity.

"Child, it is a medicine that is three parts poisonous, when treating a patient, you don't need medicine, choose the cheaper one for the same effect, don't use the expensive one, only choose the most suitable one. Doctors are benevolent, and if you want to be a good Chinese medicine practitioner, you must first have a benevolent heart. Practicing medicine is not only for money, but also for being a person, to be a useful person to the people. Gu Fan finished the last puff of cigarette, feeling a little uncomfortable, he missed his grandfather more than a hundred kilometers away.

......

"Grandpa, why is the medicine three points poison?" Gu Fan asked the old man sitting opposite.

"Traditional Chinese medicine will balance yin and yang, yin deficiency nourishes yin, yang damage aphrodisiac, this process of nourishing and warming is also helping the organs to restore balance, how to restore? In addition, substances that are not absorbed by the human body are also a kind of poison, and some drugs also act on many organs. If the ratio of medicine is not appropriate, it will affect organs that are not sick, which is poison or not, and it is also poison. Gu Zheng patiently taught his grandson.

"Isn't there a perfect prescription?" asked Gu Fan curiously with his fingers in his mouth.

Gu Zheng touched Gu Fan's head, "Silly grandson, of course there is." Every prescription that has been passed down is perfect, but the medicine is biased, and there may be slight differences in the medicinal properties of the same herbs in different growth environments, and this difference is difficult to find. ”

Gu Fan nodded thoughtfully, "Does that mean that if the drug ratio is perfect, there will be no poison." ”

Gu Zheng smiled and shook his head, "It's hard to have a perfect drug ratio, even if there is, everyone's speed of absorbing medicine is different." Some absorb a drug quickly, while others absorb slowly, which is also harmful to the body. ”

Gu Fan puffed out his little cheeks, "Huainan is orange, Huaibei is orange." Chinese medicine is so difficult. ”

Gu Zheng looked at his grandson's cute appearance and said kindly, "In the "Neijing", medicine is divided into big poison, regular poison, small poison, and non-poison. The treatment of diseases requires the treatment of major poisons, six out of ten, the treatment of diseases with regular poisons, seven out of ten, the treatment of small poisons, eight out of ten, and the treatment of non-poisons, nine out of ten. Don't try to make the perfect prescription, because the perfect prescription is not perfect for different people. For the same disease, different people, the prescription will be adjusted to a certain extent. Rather than worrying about the perfect ratio of drugs, it is better to choose a treatment that is better for the patient. ”

......

Gu Fan went to the store to buy a bottle of water, and was about to open it to drink, when he watched an old man dig out a bottle of drink from the trash can, sniffed it and planned to drink it.

Gu Fan hurriedly stepped forward, "Old man, drink my bottle, the contents of the trash can are dirty after all." ”

The old man looked at Gu Fan leaking out two rows of yellowed teeth, "No need young man, I'm used to drinking." ”

Gu Fan shook his head, "This habit needs to be changed, and I won't be thirsty." ”

Gu Fan wanted to stuff the water into the old man's hand, but the old man just refused to take it, so in desperation, he directly put the water on the trash can and turned away.

The old man looked at Gu Fan's back, then looked at the bottled mineral water, and sighed.

At noon, Gu Fan sat in a noodle restaurant, ordered a beef noodle for himself, and ate a few bites.

"Let's go, we don't have any money for you here, don't affect our business. The waiter stopped an elderly man and wouldn't let him enter the restaurant.

Gu Fan frowned when he heard the prestige, isn't this the old man he met just now?

The old man was a little embarrassed and looked inside the restaurant, "Young man, I don't want to eat, I just want to eat a bowl of noodles." ”

Gu Fan put down his chopsticks and looked at the scene outside.

The waiter snorted coldly, "Don't you see that our restaurant is full of people? ”

"Waiter, let the old man sit at my table, I don't dislike it. Gu Fan raised his hand and called the waiter.

The waiter looked at Gu Fan, then at the old man's dirty clothes, and waved his hand as if chasing flies, "Go in, go in." ”

The old man nodded to the waiter, and walked towards Gu Fan's table with a sluggish step.

Seeing the old man limping towards his table with a limp, Gu Fan stood up directly and helped the old man sit down. "Old man, what do you need?"

The old man looked at Gu Fan with a smile, "Young man, let's meet again." ”

Gu Fan smiled in return, "Yes, old man." ”

The old man looked at the menu, "Do you have somen noodles?" ”

The waiter stood beside the old man and said disgustedly, "No, we only have beef noodles, oily noodles, beef ramen, and fried knives here." ”

The old man looked at the order board on it, hesitated for a moment, and prepared to stand up and leave.

Gu Fan took the old man's hand, "Old man, sit down, I invite you to this meal." Turning his head, his smile disappeared, "Here's some beef noodles, and cut me another plate of beef." ”

The waiter looked at Gu Fan, cut lightly, and arranged the back kitchen.

The old man looked at Gu Fan, "Young man, how embarrassing is that, I'd better leave." ”

"The meal has been ordered, and the waiter will not give it back, how can I finish eating when you leave, won't it be a waste if I can't finish eating?" Gu Fan did not let go of the old man's hand, but stood up and asked the old man to sit down.

The eyes of the people around looked at Gu Fan, they thought that Gu Fan was just sympathizing with the old man, but they didn't expect him to do this.

The old man looked at Gu Fan gratefully, "Thank you, thank you, young man." ”

Gu Fan smiled, he didn't say you're welcome, sometimes the politeness of the transition will seem rusty, making the old man feel that this is a kind of pity.

The noodles came up, and Gu Fan took a pair of chopsticks to the old man.

The old man thanked him again and again, which made Gu Fan a little embarrassed.

Watching the old man eat noodles with his head down, he didn't clip the beef on the plate at all. Gu Fan somewhat understood the old man's thoughts, so he didn't make a sound, and directly took another pair of chopsticks and sandwiched two large chopsticks of beef into the old man's bowl.

The old man looked at Gu Fan's gaze, his eyes were a little moist.

Gu Fan glanced at the old man and said comfortingly, "Eat." ”

Looking at Gu Fan, who had already lowered his head and started to eat noodles, the old man wiped the tears from the corners of his eyes with his sleeves.

After Gu Fan finished eating noodles, he took out his mobile phone and began to browse the news.

The old man picked up the bowl, drank the last mouthful of soup from the bowl, and wiped his mouth with his sleeve. "Thank you, lad. ”

"It's okay, I can't eat a meal. Gu Fan took out his wallet and prepared to pay the bill.

The old man hesitated, and carefully took out a tightly wrapped handkerchief from his waist. There was some paper money in the handkerchief, the coins were dirty and crumpled, but they were neatly rolled together.

The old man counted out dozens of dollars and put them on the table, "Young man, I invited you for this meal." ”

Gu Fan made a straight face, "Old man, didn't you slap me in the face?" I said that I was invited, where do you tell me to put my face like this." ”

The old man smiled awkwardly and took the money back.

Gu Fan finished paying the bill and was about to get up and leave. The old man hurriedly stopped Gu Fan, "Young man, wait a minute." ”

Gu Fan glanced at the old man and sat down again. "Old man, what's the matter?"

The old man squatted down, took out a small wooden box from his bag, and touched the dust off it.

Gu Fan looked at the contents of the box, his pupils shrank, and he raised his head to look at the old man's eyes full of respect, as well as respect.
