There was a lot of snow this year. The snow melted the other day, and a thin layer of ice formed on the road. The snow came again, covering the earth with a new layer of white, and time slipped away in this staggered snow. The final exams are approaching, and even someone like Chen Ying, who is good at using his time, is a little scrambling. She had to juggle her own exams, tutor students' exams, and be a teaching assistant at the same time. She was either in the classroom or in the library every day, and sometimes her lunch was solved in the corner of the library. Qin Hong helps her get up early every day to occupy a seat. She came, busy for a while without raising her head, and then went out against the cold wind. Qin Hong is not much better than her, he checks the recruitment websites of major companies on the Internet every day, fills in resumes, and then constantly looks at his mobile phone or swipes the inbox of his email, and he is nervous once he sees unread emails. He is like a frightened bird, and a promotional email can also make him excited for a long time.

They were so busy that they didn't even go out for a few days off in the New Year, until the final exam of Chen Ying's last class was over. But that afternoon, Chen Ying had to go to the invigilation exam, and in the evening, she had to correct 145 papers. The calculus exam is on the fourth floor of the first academic building. It is a newly built school building with beige marble tiles and floor-to-ceiling windows with gray borders. As if to prove that modernization can improve the quality of life, the white heating in the building is boiling hot, and the temperature in the entire school building is much higher than outside, and some boys even wear short sleeves in the building.

As soon as the bell rang at half past two in the afternoon, Chen Ying walked to the door of the scheduled classroom and waited. The people from the previous exam came out one after another, some relaxed, some depressed. Chen Ying walked in, kicked out the few remaining students who were still correcting the answers, wrote the subjects and time of the next exam on the blackboard with chalk, and put the thick stack of test papers on the podium table. She sat on a high chair behind the lectern with her left hand on her forehead, looking out the window at the playground. The whole playground was covered with snow, and two or three boys who were not afraid of the cold were still playing there. The basketball hit the rebound and reverberated across the empty playground. There was not a single person on the plastic runway. There are rows of bicycles parked outside the playground fence. The students who took the exam came and went, which was a little angry in this cold campus. Chen Ying took off her heavy down jacket and wore a thin gray cashmere sweater. She habitually opened her SMS inbox and patiently waited for the arrival of the students.

At 10 a.m., she began handing out exam papers to the already full classroom, instructing the students who sat too close to each other to separate and move to new positions. She then stood back on the podium and read out the school's disciplinary and disciplinary measures for the exam. After reading the last few words, she looked around to see if she had started writing earlier. Soon the bell rang, and all that remained in the classroom was the rustle of pens scratching on paper.

Before you know it, the snowflakes outside the window are floating again, accumulating layer by layer on the outer edge of the window sill. It was getting dark, and it was a sign of the end of another day. Chen Ying observed the situation in the classroom, occasionally looking at her watch. It was a rare break of the day, and she stretched out her arms under the lectern to soothe her somewhat stiff shoulders. At this time, her phone shook slightly.

"Shall we have dinner together?"

It's Qin Hong's text message. He was probably still waiting for her in the library.

"Probably not, we have to mark the papers collectively at night." She finished writing these words and sent them out.

He replied with a sigh.

After a while, he sent another sentence:

"I got an interview and I'm going to go next Monday."

"Okay, please prepare." She replied to him with a smiley face.

The professor walked over to inspect the examination room, and when he saw the students answering the questions quietly, he beckoned to Chen Ying. She walked briskly over. The professor whispered to her that after she had finished collecting the papers, she and the teaching assistants of the other two classes would go to the small hall of the mathematics group to discuss the marking of the papers. She nodded. The old professor took off his cap, walked around the classroom, checked the students' answers from time to time, and then left as little as he could.

Suzu –

The bell rings for the end of the exam. Chen Ying stood majestically in front and asked the students in the last row to pass the answer sheets forward. As she collected the papers, she reprimanded a few students who tried to add a few more strokes. She counted the number of answer sheets, sealed them in a brown paper bag, and collected the papers.

When she finished counting, the students rushed out, and the classroom became empty in an instant. This is the last exam of the semester, and the professor somehow deliberately increased the difficulty before the exam, looking at the dark circles of the students just now, Chen Ying knew that this course was not less. Although the results are unknown now, it is a temporary relief. She smiled and shook her head, loaded the paper into her backpack and headed towards the math group.

Calculus is a compulsory public course for the whole school. Liang Jing is also working as a teaching assistant for this course. They took the exam papers of their respective classes, gathered in the auditorium of the mathematics group, and handed them to the professor. After a cursory discussion of the criteria and division of labor for judging papers in the evening, everyone dispersed to eat. Chen Ying and Liang Jing walked together to the cafeteria closest to the teaching building. Meals in this cafeteria are placed on the assembly line, and students can put whatever they want to eat into their own trays, and then pay with meal cards at the exit.

"Your class is still going well, right?" Liang Jing picked up a small bowl of vegetables and put it on the tray a little tiredly, "There was a girl on our side who refused to hand in the paper just now, and she kept writing when the bell rang - I almost tore her paper." ”

"And then?" Chen Ying picked up a flower roll.

Then she lay on the table and cried. I comforted her. She probably didn't review it properly, and many of the questions were left blank and not written. ”

"Will it hang up?"

"I think it will. I don't know how she did the previous little question. ”

"I noticed her when she answered the questionnaire just now, and the whole person was very nervous, from our psychological point of view, it was a temporary disturbance in hormone secretion levels, resulting in emotional out-of-control."

"You're still in the mood to say that." Chen Ying was a little sympathetic to the girl she hadn't met, "I think it's a little more difficult to solve this problem, and the last two big questions are estimated to not get points if you only memorize the formula, but how many students can really learn calculus in one semester - most of them just draw a scoop according to the gourd." Oh, how much? ”

It was a total of 15 yuan, but Chen Ying's meal card was only 12 yuan. The credit card machine sounds a low balance.

"What's going on? Forgot to charge your meal card? Liang Jing preemptively handed over her meal card, "This doesn't look like your style." ”

"Well, I've been doing a lot lately, so I forgot."

"A person as strict as you can forget? Could it be that your handsome dinner partner has disrupted the rhythm of your life? ”

"This matter has nothing to do with Qin Hong, and besides, he is not a food partner."

"So it's not just a dinner partner?" Liang Jing casually said as she took a spoonful of porridge from Chen Ying's bowl, and after drinking it, she took another spoonful. Then she asked faintly, "Did you kiss?" ”

The soup spoon in Chen Ying's hand fell into the tray with a thud. She grabbed Liang Jing's hand, blushed and said, "Don't tell others." ”

"Don't worry—I've never told anyone about you." Liang Jing didn't raise her head, as if she didn't see Chen Ying's embarrassment, "How far have you go?" Do you have any ......?"

"Nope."

"It's okay if you tell me."

"Not really." Chen Ying said categorically.

"Well, you're pretty cautious."

Chen Ying didn't know if this was a compliment. She didn't answer.

"When and where did you kiss?" Liang Jing continued to ask.

"That...... At...... We hostel. ”

"The time he went to your dorm?"

"Pretty much."

"Ahh Liang Jing closed her eyes, "If I say it in the high school group, I don't know who will be unhappy." ”

"Please......" Chen Ying looked at her with earnest eyes.

"Alright, alright. I'm just teasing you. Liang Jing had already drunk the entire bowl of porridge and began to wipe her mouth, "You have always been unsmiling, I used to fantasize about what it would be like if you fell in love one day - I didn't expect this day to come so soon." I just hope that he can love you well and take care of you, so that you don't have to work so hard to make money everywhere. When you get married, remember to invite me to be your bridesmaid. ”

"Hmm. In fact, he is also very hard-working, and he has been submitting resumes recently, and today he said that he received an interview opportunity. ”

"That's good, good men need to watch it tightly."

After saying this, the two of them laughed together. The students around them were almost gone, and the plates in front of them were empty. Chen Ying looked down at her watch, it was almost eight o'clock in the morning.

"Let's go to the math group to mark the papers." Liang Jing took Chen Ying's hand and walked out of the cafeteria.
