Sine theorem

Chapter 10

"Xiao Jin, let's go. If it's later, we'll be late."

Xie Ting looked at Yan Jin who was sitting at the dining table eating steamed buns, he had already carried the steamed stuffed bun.

"Well... good." Yan Jin drank the last sip of milk, and thanked Teacher Xie for being a good man at home.Not only is she good at studies, but she can do everything. She is really the first choice for a practical marriage partner.

Xie Ting allowed enough time for the two of them to walk to school, so they didn't take the bus. In the early autumn morning at 07:30, there was a warm but not glaring sun, shining warmly on people.

Both of them were carrying schoolbags, and Yan Jin didn't wear the school uniform of Nineteen High School either.Walking together is like classmates, and they look extraordinarily warm and peaceful—if Teacher Xie’s voice is blocked.

"Xiao Jin, you have to be aware of your own problems. Liberal arts is good for that. If you don't understand history and land politics, you can go and read more after class. But mathematics is not enough." Xie Ting paused , "Mathematics, as the only science subject in the liberal arts, is particularly important to widen the gap in scores."

Yan Jin has long been used to being educated by Yang Wenbo, Hong Shifeng and others, so she didn't show any surprise at all.Smiling and walking side by side with him, and answering a few words from time to time.

"Is there anything you didn't understand in class?" Xie Ting had already seen that this person was perfunctory here, and turned his head to look at him.

"Yes, I didn't understand everything. But Teacher Xie taught very well, and it's not because of you."

Xie Ting hugged his chest: "I heard that you are a direct student of the [-]th Middle School."

Yan Jin was stunned for a moment, and then said calmly: "That's right, a hero doesn't mention his bravery back then. What was great in the past may not be as good as it is now."

"You're lying." Xie Ting raised his eyebrows, "Most of the direct admission students of the Nineteenth Middle School went to high school to prepare for the competition application, and they all filled out the competition application, right? According to your admission file that Team Leader Yang showed me, You filled in mathematics. You scored 118 in the high school entrance examination, right?"

Yan Jin smiled noncommittally, "That was before."

"Why don't you learn? It's because you..."

Yan Jin's tone suddenly turned cold: "Mr. Xie, school is here. I'll go first, and I'm finally not late. I haven't run for exercise yet." After finishing speaking, she turned around and walked towards the playground.

Xie Ting stood where he was, calmly watching the boy go further and further away, until he turned into a small black dot before retracting his gaze.

Yan Jin, what happened to you?

——Grade [-] and [-]

Yan Jin did not go for exercise, but turned a corner and returned to the classroom to continue lying on her stomach.There was no one in the classroom except him, and it seemed deserted and peaceful.He raised his head, half-length hair covering part of his vision.Flying dust danced in the sun, and there were traces of old chalk writing on the blackboard that could not be wiped clean.The wind gently blew over the exercise book spread out on someone's desk, and a few pages of "Salad Salad" were turned.

The sun was shining outside the window, but I was alone in prison.

Yan Jin stared blankly at a certain place outside the window, watching very seriously and intently——

Yan Donghai and Lin Yuan had a very sweet time.Although they were also married in a business relationship, they also lived with He Meimei.Yan Jin was born in the third year of their marriage, and the life of the two of them did not become dull because of the birth of the child, on the contrary, it became even more sweet.

But the good times didn't last long. Three years later, Lin's consortium encountered financing problems, and the operating conditions of the entire company took a sharp turn for the worse, and eventually went bankrupt.Lin's consortium announced its dissolution.

In the same year, Yan's Group acquired Lin's Consortium and became a leading enterprise in the city.

The young Yan Jin watched Lin Yuan, who was already skinny, lose weight day by day, and her whole body took on a sickly whiteness.The sweet life of the husband and wife has gradually disappeared. The relationship between them is like a bowl of honey mixed with water. No matter how sweet it was once, it will become dull with the increase of water.

They were silent at first, and then quarreled in low voices.Even later, as soon as they met, they started to quarrel.

Later, Yan Jin was sent to his aunt - Lin Yao's house.Lin Yao treated him very well, Yan Jin once made a serious wish that when she grew up, she would treat her aunt very well.If it wasn't for what happened later, Yan Jin would have kept this wish well in her heart, waiting for the little boy to grow up before fulfilling this wish.

But why is it my aunt?why?

Yan Jin couldn't think about who was right and who was wrong, who benefited and who lost.

Fortunately, the dust has settled...

The running students finished with exhaustion and sleepiness, and some diligent students even took out small booklets and worked hard on their backs.Yan Jin withdrew her sore eyes, but didn't feel sleepy.But he still pretended to fall asleep and lay down.

Instead of his flashy headphones, he pulled out a bunch of knotted cables today.It took him 5 minutes to untangle the headphone cable.By the time he bent down/body up again, a few people had already entered the classroom sparsely.

"Yo, Brother Jin? Why is it so early today?" Little Fatty was the first to notice Yan Jin who was lying on the table. "Brother Jin, what happened last night?"

When Yan Jin raised her head, she saw that little chubby put both hands on his desk, and was wagging his eyes at him.He immediately clapped his hands away.He said with a worried expression: "Get out, I'll catch up on sleep."

The little fat boy smiled "hehe", "That's right, I was so tired last night, so I won't bother Brother Jin to rest."

Yan Jin rolled up a book that was casually spread on the table, and made a gesture to hit him.Little Fatty was so chubby, he jumped to the last row in no time, covered his mouth with a book, only showing a pair of rolling eyes, indescribably cunning.

Yan Jin didn't bother to talk to him, and put on the earphones again to keep company with all kinds of cats in his phone.After a few sessions of integration, they all failed.Yan Jin was so irritated that she couldn't explain it, she simply threw the phone aside, closed her eyes and fell asleep.

When he woke up again, he was patted awake.I don't know how many classes have passed, and I didn't even see the faces of several teachers.Xie Ting looked at him raising his head in a daze, his eyes were full of sleepiness that had not yet faded.

"Student Yan, have you had enough sleep?"

"Enough sleep, enough sleep." Yan Jin sat up straight and realized that this class was a math class.

There was meaningful laughter from the boys in the back row.Yan Jin turned her head and gave Little Fatty a look, meaning to tell him to shut up.

The little fat boy smiled even more heartily.

Xie Ting tapped on the blackboard, "Okay, since everyone is fine. Let's talk about the basic algorithm today..."

People always have a 3-minute enthusiasm for new things, and the wonderful people in Class [-] are also interested in Mr. Xie himself...and his math class.

But this little interest disappeared within a quarter of an hour.Those who should live in the crotch should still live in the crotch, and those who should sleep should still sleep.Xie Ting glanced down from time to time, and found that almost no one was listening to the class—except for the boy who voluntarily stayed to listen to his lecture yesterday.

Xie Ting wanted to train him well, so he made eye contact with him again and again.Yan Jin, who squinted his eyes, saw them come and go several times, and suddenly felt a little uncomfortable.He glanced at the topic on the blackboard and found that he could do it.So he raised his hand just in time before Xie Ting was about to flirt with Zhu Yan again.

"Thank you teacher, I will answer this question."

Xie Ting was a little surprised, "Then you can talk about this question."

Yan Jin finished his solution to the problem unhurriedly, and Shi Shiran sat down in the eyes of everyone's astonishment, astonishment and sudden realization.It seems to be saying silently: "Look at how powerful I am, I just didn't want to tell you before."

Xie Ting said in his heart that he was indeed a straight-up student from the Nineteenth Middle School, and his problem-solving ideas were simple, convenient and effective.

He raised his eyebrows to cover up the praise in his eyes - he can't praise now, some people will float when they praise.I don't know what will happen then.

"Yan Jin did a good job on this question. It seems that my hard work yesterday afternoon was not in vain. Students who want to improve their math scores can also come. I will welcome you very much." He thought for a while, then said : "After class, Yan Jin and Zhu Yan come to my office."

After finishing speaking, he ignored the "shh" sounds behind him, and continued his lecture unmoved.
