Knowledge and Practice

"Aren't you going back to tidy up your things?" Zhang Chengyu stuffed the medical certificate into his schoolbag and planned to go to the dormitory.

"I fixed it in the morning," Xiao Xingyi said, weighed the weight of the medical certificate, and began to hesitate whether to take it back to celebrate the National Day. After thinking about it, he still stuffed it into the bag.

I didn't know what was said in the biochemistry course in the morning, and I wrote down the diagnostic notes in the afternoon, but most of my mind was in a state of fugue.Just thinking about going back today, I am not in the mood to listen to the class. It seems that I have to review it when I go back.

"Okay, then I'll go back to the dormitory first." Zhang Chengyu said goodbye and left the classroom.

It's 2:40pm now, everyone was rushing home for the National Day, even the teacher was released early, Xiao Xingyi sat in the classroom bored, took out the medical certificate from the bag, felt that it was not enough, and then sent the biochemical Also took it out.

Xiao Xingyi himself felt that he was not very confident in his knowledge reserve after changing his major. He became more and more uneasy after he missed a class today.

Although the grades he said were good, compared with those talented and intelligent people, he didn't seem to be that kind of thing.

Or maybe he has this medical talent himself, but he doesn't know it.

"Tricarboxylic acid cycle..." Xiao Xingyi read the book involuntarily, and drew around the picture. The chemical reaction on a circle is basically the same as that in the heavenly book. .

"..." What the hell, Xiao Xingyi began to mutter in his heart, the book is so difficult, it really showed the final curse of "physiology and biochemistry, there must be a hang" from the beginning of school, so he began to copy it on the circle repeatedly , Putting pen and volley on my draft, gesturing equations in front of the air, trying to remember the strokes in the air into my mind.

"What are you doing?" A gentle voice came from beside him, and before he knew it, Xie An had already walked to the side of Xiao Xing who was obsessed with drawing circles in the air, and he looked at this child who was obsessed with biochemistry books , couldn't help but feel happy, and said with a smile, "I see you came into the school to take a look before you came out, and saw you here after a while, are you trying to practice equations out of thin air?"

Hearing the sound, Xiao Xing raised his head and looked at Xie An with a smile on his face. The brain nerves that usually responded with a smile seemed to go dormant. Xie An remembered it.

"No, let's go back." Xiao Xing followed behind Xie An one meter away as if angry. It was almost a holiday, and the school security did not stop the parents' pick-up car. The green belt was full of cars, and he didn't take a few steps. The road is here.

Xie An sat down in the driver's seat, and when he glanced at the rearview mirror, Xiao Xingyi had already sat in the back row, with his head down, unable to see his expression clearly.

This kid, is he making a fuss?This thought flashed through Xie An's mind, the kid even took the book back, so seriously, he shouldn't have teased him just now.

The car slowly drove out of the school, the nearby university town, the cars going back from school today were all moving slowly on the main road, Xie An drove slowly, the camphor trees on the roadside in early autumn had not completely turned yellow, the afternoon sunshine The light shined into the car window freely, and Xie An's thoughts scattered like the afternoon sun.

Hmm... how to discuss this with this kid?

"Xingyi, do you still remember that I told you about my house?" Xie An mentioned carefully

"Well... I remember, what's the matter?" Xiao Xingyi still remembers when Xie An was in the orphanage in junior high school, Xie An patiently explained the situation of the house and accommodation to him. At that time, Xie An had just been trained , All kinds of troubles were met, and the director of the orphanage asked him about Xiao Xingyi's whereabouts, so he couldn't bear to let the child live with him in the hospital dormitory.

At that time, he actually seemed to understand, but Xie An still told him the whole story honestly. When he got older, Xiao Xingyi went to high school. He spent most of high school in the dormitory. During the semester and the winter and summer vacations of the third year of high school, I basically stayed in school, and rarely returned to the orphanage.

Later, during the summer vacation, he basically developed the habit of staying in school or working part-time, and rarely went back to the orphanage. Xiao Xingyi didn't go to know about the housing market situation, but he could feel it from Xie An's words. Xie An had a hard time running around to make a living, and he had no particular obsession with where he settled, whether it was from an orphanage or a school.On the contrary, Xie An would take regular monthly and weekly tutoring courses for him, and let him cherish all the days of chatting with him. These are enough to support his peaceful life and become a lasting and stable foothold in the years of growing up. .

"It's like this. In the first half of the year, the approval for the talent apartment has come down. It's well-decorated, with two bedrooms and one living room, and it's not far from the hospital." It took not too long to get a foothold in this city from the beginning. Little Bean Sprout was almost growing taller than him. He couldn't take care of Xiao Xingyi, who was still Little Bean Sprout at that time, by his side. He is so ashamed that now that he is finally capable, he is still a little uneasy.

Xie Anping regained his composure, and carefully captured Xiao Xingyi's facial expression in the rearview mirror, not daring to miss his every change, and continued, "I installed an eye protection lamp in your room, and there is an eye protection lamp in the bookcase. Books I've used."

"If you don't stay at school during the holidays, come back." After Xie An's gentle request, seeing that there was no sound in the back row, he couldn't help but feel a little timid. Sure enough, nothing is more difficult than communicating with children. Then he thought of Xiao Xing and his wife. Drawing circles on the tricarboxylic acid cycle, he tentatively said, "I can teach you how to draw a tricarboxylic acid cycle..."

"..." (Xiao Xingyi was silent) It seems that the effect is not ideal, which pot does not open and which pot is lifted

"Well, when the time comes, the Department of Internal Medicine and Surgery will give you make-up classes in advance, so you can take it easy in class in the future, as long as it's time for roll call, you can do what you want when you are free."

"..." (Xiao Xingyi is still silent) It seems that it shouldn't be said like this, teaching bad children

"If you want to practice in the summer, you can choose a place close to home. I can take you in the hospital, but the department may be limited..."

"..." (Xiao Xingyi remains silent) Still no response...

The return journey had already been driven a bit, and the afternoon sun was getting darker and slanting. Xiao Xingyi listened to Xie An's slightly nervous words, and at the same time repeatedly confirmed Xie An's meaning in his heart. He was repeatedly recording these words, together with the surrounding The sunny road at this moment is recorded together.

Like a person who has been trapped in a swamp for a long time, suddenly touching a new vine.

Or a ship drifting at sea, seeing a lighthouse shining with warm light in the distance.

Or the migratory birds that have been migrating, finally found the island where they settled

And those turbulent and indescribable emotions finally merged into one word, which leaked out from Xiao Xingyi's mouth with a little timidity.

"it is good"

I don’t know if it’s because the afternoon sun is too dazzling, the surrounding vision seems to become blurred, the green leaves on the street outside the window are blurred with the sunlight, Xiao Xingyi closed his eyes, rubbed them, and looked up again, the sight outside the window The scenery was restored to clarity.

It was the thickest promise he had heard in these years, and the moment he closed his eyes, he could clearly feel its temperature.
