On January 13, 2005, the temperature was low, the wind was cold, and snow fell from the sky, covering the green tiles and red bricks in the streets and alleys.
Jiang Yubai held up an umbrella and walked into the gate of Provincial No. 1 Middle School.
The driver shouted behind him: "Mr. Jiang, your water cup fell on the car!"
"It's okay, I'm not thirsty. I'll hand in the paper early," Jiang Yubai replied calmly, "Mathematics is my best subject."
It's time to prove yourself!
Jiang Yubai was full of confidence.
The snow was falling all over the sky, first like catkins, then like feathers. Jiang Yubai held an umbrella, walked alone in the wind and snow.
Light snowflakes fell beside his ears, and he heard a familiar voice: "Jiang Yubai! Jiang Yubai! Wait for me!"
Jiang Yubai stopped but did not turn around.
Lin Zhixia rushed towards him and said, "Jiang Yubai, how are you reviewing? Are you 100% sure?"
Jiang Yubai raised the edge of his umbrella slightly, then tilted it to the side, covering Lin Zhixia's head. He casually revealed, "I have a math tutor team. They gave me extra lessons for a week."
"Great!" Lin Zhixia said confidently, "You can definitely finish the entire test paper!"
Jiang Yubai's self-confidence soared, and he couldn't help but hold the umbrella handle tightly.
It is freezing cold today, with a biting winter wind. Fortunately, there is a cabinet air conditioner in the examination room.
Two air conditioners worked together to maintain a constant indoor temperature of 23 degrees. The warm wind blew on the students present. Their expressions were either solemn or nervous. Some were so nervous that they could only keep adjusting their breathing.
But Lin Zhixia didn't feel anxious at all.
She has never been afraid of taking exams.
The so-called "exam" is more like an interesting game to her.
She sat down calmly and waited for the invigilator to hand out the test papers.
Compared to Lin Zhixia's casual attitude, Jiang Yubai was "fully prepared." He laid out his ruler, pen, eraser, compass and other stationery items in order, placing them neatly.
When he got the test paper, he reviewed the questions immediately.
The questions on this paper are very profound, requiring a broad range of knowledge, a huge amount of calculations, and sophisticated problem-solving skills.
Jiang Yubai did not dare to neglect it. He thought carefully and drafted seriously.
After seven minutes of careful consideration, Jiang Yubai solved the three multiple-choice questions on the test paper.
At the same time, Lin Zhixia also finished the entire test paper, including the additional questions. In order to kill time, she provided two solutions for each big question.
When answering questions, ordinary students usually write the word "解".
When answering the question, Lin Zhixia first wrote "Method 1, solution", and then "Method 2, solution". In fact, she could have written Method 3, but she was a little lazy.
She closed the pen cap and glanced around.
Apart from her, most of the students were racing against time and doing their homework like crazy. They wrote furiously with focused expressions.
There was also a small number of students biting their pen caps with a bitter look on their faces, enduring the brutal torture of math problems. To them, the entire examination room was not like the human world, but like the eighteen levels of purgatory - the test paper was torture, the stationery was shackles, and the admission ticket was shackles that could not be broken free.
Lin Zhixia watched their expressions with curiosity.
The invigilator tapped her desk gently and said, "Student, please stop looking around."
Lin Zhixia nodded in greeting. Then, she stretched and lay on the table to sleep.
The tiered classroom of the Provincial No. 1 Middle School was very well designed. Each seat had a cushion filled with sponge, which felt soft to sit on. The desk was also very spacious. Lin Zhixia relaxed physically and mentally and fell asleep.
The only sound in the classroom was the rustling of pen tips rubbing against paper.
Precious time is passing by every second.
Jiang Yubai had just finished writing on the fourth page of the test paper when the additional questions gave him a warning.
This additional question describes "non-coplanar point sets and binary subset line segments" and requires students to find the smallest positive integer n based on the known point set conditions, so that "the set composed of line segments has n elements, the binary subset line segments have common intersection points, and the intersection of the subsets is an empty set."
Jiang Yubai calmly reread the question, a drop of cold sweat on his forehead. It was too difficult. He had no idea and couldn't even understand the question.
Since last week, Jiang Yubai has had four math tutors and a math teaching and research team. The teachers tailored a learning method for him and summarized hundreds of question types for him.
However, he still fell into the trap of the additional questions.
Jiang Yubai turned his head and glanced at Lin Zhixia. The scene before him shook his soul. Lin Zhixia was sleeping peacefully on the table. Her eyelashes were trembling and her cheeks were pink. She was sleeping so soundly.
Has she finished writing
She must have finished it.
This is her strength.
There were still thirty minutes left before the exam ended. Jiang Yubai gave up on the additional questions. Even if he was given more time, he had no idea how to solve the questions.
He raised his hand high, saying that he wanted to "hand in the paper early." So the invigilator took his paper away.
Jiang Yubai stood up calmly, pretending that he was too weak to hold an iron pencil case. The heavy iron pencil case fell to the ground with a "snap", and as he wished, he woke up Lin Zhixia.
As soon as Lin Zhixia opened her eyes, she saw Jiang Yubai.
She followed closely and handed in the paper immediately.
The invigilator came over to her and saw that her test paper was covered with traces of answers. However, Lin Zhixia was almost sleeping the whole time. How could she finish the test? She even came up with two solutions to the additional questions
There were more than two hundred examinees in the first-level classroom.
These more than 200 students come from some of the best primary schools in the city, including many sixth-grade seniors from Experimental Primary School.
The seniors didn't dare to hand in their papers early, but Jiang Yubai and Lin Zhixia both walked towards the classroom door.
Jiang Yubai asked Lin Zhixia: "Do you think the test paper is difficult?"
Lin Zhixia answered honestly: "It's so simple!"
Good, simple, ah.
Those four words were like a terrifying demonic sound, disrupting the quiet atmosphere in the examination room.
The invigilator had rich teaching experience. He quickly stood up on the podium and shouted, "Keep quiet, students, don't whisper! Pay attention to exam room discipline! There are still 30 minutes before the end of the exam!"
Lin Zhixia stood outside the examination room and could still hear the invigilator's roar.
She grabbed her schoolbag and followed Jiang Yubai out of the school.
"Jiang Yubai, how did you do in the exam?" she asked without any hesitation.
Jiang Yubai hesitated for a few seconds before saying, "I don't know how to answer the last additional question." After saying that, he held the umbrella in his left hand, put his right hand in his pocket, and his gaze extended to the farther horizon.
As he expected, Lin Zhixia was surprised. She murmured to herself, "Are the additional questions difficult? Are they really difficult?"
She was stuck in a swamp of confusion, unable to tell what was easy and what was difficult. She also helped him sort out his thoughts: "You can build a connected graph, substitute the connected branches and permutation and combination formulas..."
"I haven't learned about connected graphs." Jiang Yubai told her.
"What about other students? It's even more impossible for them to have studied it!" Lin Zhixia found a breakthrough point, "The test is about the ranking, not the total score. Even if you only scored 20 points, as long as you are in the top 70, the 2005 competition class will definitely accept you."
Jiang Yubai has never scored above 20 points in an exam.
In fact, if the full score of the test is 100, Jiang Yubai has never scored lower than 97.
Jiang Yubai looked at Lin Zhixia with a complicated expression.
Lin Zhixia thought Jiang Yubai was worried about his grades.
Without any time to hesitate, Lin Zhixia made a prompt decision and took Jiang Yubai back to the lecture hall. They waited for more than ten minutes until all the students in the examination room handed in their papers. Lin Zhixia caught a few people on the spot and asked, "Hello, classmate. What do you think of the overall difficulty of this math test?"
The student being interviewed was about twelve years old. He wore a pair of black-framed glasses, looked haggard, had messy hair hanging on his forehead, and was a little dazed: "Hehe..." He laughed sadly: "Hehe... the math test paper... was so easy!"
"Simple?" Jiang Yubai asked in astonishment.
At first, Jiang Yubai thought that he could get into the competition class with his eyes closed. But after listening to the description of the unknown classmate, Jiang Yubai began to doubt himself.
Lin Zhixia comforted him: "Don't be afraid, you are very powerful! Jiang Yubai!"
Then, Lin Zhixia found another girl and asked persistently: "Hello, classmate, excuse me, what do you think of this math test..."
Before Lin Zhixia finished speaking, the girl threw away her schoolbag and cried loudly. This girl came to take the exam with her elementary school classmate. Both girls did not do well in the exam and cried together in the corridor.
The air was filled with sadness, worry, and frustration.
Lin Zhixia was shocked by them. This was her first time to get close to a group of ordinary students who failed the exam.
She calculated the probability of admission. 287 people took the exam, but only 70 students were admitted, with an admission rate of only 0.2439. She randomly interviewed the candidates, which was equivalent to random sampling. The sample did not include Jiang Yubai and Lin Zhixia, so the probability of her picking two students who were destined to be eliminated was as high as 0.58.
She interrupted the interview and headed for the stairs.
A young man's voice came from behind: "Are you the one who fell asleep for more than an hour, handed in the paper early, and said that the paper was easy?"
Lin Zhixia turned her head and saw a boy who was about twelve years old. The boy had a short haircut, handsome features, a high nose bridge, and was wearing a black long coat. The index finger and thumb of his right hand were stained with dark blue fountain pen ink.
He walked down the stairs step by step: "I am the winner of the first prize of the provincial Hua Luogeng Elementary School Mathematics Competition in 2004. I went to Beijing to participate in the competition. How about you?"
Someone around him pulled him back and shouted, "Duan Qiyan, the number one god of war, stop competing with girls."
Another classmate echoed: "Duan Qiyan is in the primary school attached to the Normal University. He ranks first in the school every year. His nickname in school is 'No. 1 God of War'. We all know it."
Duan Qiyan pulled his arm back and glared at Lin Zhixia: "You and that boy handed in the paper half an hour early, disrupting many people's plans. You slept for at least an hour in the examination room. You two are obviously slackers. Slackers should just stay at home and don't come to the competition class's examination room to make trouble."
"Your name is Duan Qiyan?" Lin Zhixia raised her chin, her momentum not weakened at all, "I am Lin Zhixia, Lin as in the tree that stands out in the forest, Zhi as in self-awareness, and Xia as in the summer insects that talk about ice."
So arrogant!
Lin Zhixia is so arrogant!
Jiang Yubai has known Lin Zhixia for almost half a year, and this is the first time he has seen her so arrogant.
Obviously, Lin Zhixia was very angry. She hated it when people said Jiang Yubai was a slacker. Those people had no idea how hard Jiang Yubai worked! How diligent! How self-disciplined!
Lin Zhixia's cheeks flushed red, like a kitten with its fur standing on end.
Duan Qiyan was not afraid of her at all. He leaned against the handrail of the stairs and sneered, "Lin Zhixia, what qualifications do you have to be so arrogant to me? Have you ever participated in a competition? Can you tell the difference between rational numbers and irrational numbers? You should keep your mouth shut if you are a jerk."
Jiang Yubai immediately raised his hand to stop the angry Lin Zhixia, and said, "Lin Zhixia and I have never participated in the competition. We are students in Class 1, Grade 4 of Experimental Primary School."
"They're only in fourth grade?"
"A fourth-grade kid is participating in the selection for the provincial No. 1 Middle School's competition class?"
“Have you been here?”
There were noisy discussions all around. Jiang Yubai began to set a trap: "My last name is Jiang, and my name is Jiang Yubai. The seniors in the sixth grade of Experimental Primary School should know us. Duan Qiyan, let's make a bet. If Lin Zhixia's final ranking is higher than yours, you call me Teacher Jiang. If Lin Zhixia's ranking is lower than yours, I will call you Teacher Duan."
Duan Qiyan frowned: "Why should I agree?"
Jiang Yubai asked back: "You don't dare to bet with me? You are a sixth grade student, are you afraid that the fourth graders will surpass you?"
Jiang Yubai's method of provoking the opponent was just right.
The sixth graders from Experimental Primary School had already recognized Lin Zhixia and showed a horrified expression. But Duan Qiyan still accepted the challenge and said, "Okay, Jiang Yubai, you are doomed to fail. I have done the additional questions, have you done them?"
Although Jiang Yubai didn't even understand the additional questions, he still looked at Duan Qiyan with pity and asked, "If you lose, you must stand on the podium on the first day of the first grade and publicly call me teacher. Vice versa, I will do the same."
A few minutes ago, Lin Zhixia's words "Lin, the tree that stands out in the forest, Zhi, the self-knowledge of the insects, Xia, the chirping of ice" left a deep impression on Duan Qiyan.
She expressed a subtext: I am the tree that stands out in the forest, but you have no self-awareness. I will not talk to you about ice like a summer insect.
Lin Zhixia's insults did not contain any curse words, which was a very annoying way of arguing.
What's more, it was Lin Zhixia who was wrong first.
It is an unwritten rule that during long-distance races, athletes cannot start early or sprint hard in the first lap.
What about Lin Zhixia? She slept for more than an hour and handed in her papers early with her classmates. This unlearned slacker not only undermined the exam rules, but also trampled on the spirit of the competition.
Duan Qiyan became angrier the more he thought about it. He shrugged and said, "Jiang Yubai, if you want to play big, I'm happy to accompany you."
Jiang Yubai nodded: "See you when school starts in September."
Duan Qiyan said aggressively: "I expect you to bow to me on the podium and call me Teacher Duan."
"Do you want to bow again?" Lin Zhixia interrupted.
"Do you dare?" Duan Qiyan looked at Jiang Yubai.
"I dare," Jiang Yubai replied, "Of course I dare. You are no match for Lin Zhixia."
Jiang Yubai believed in Lin Zhixia so firmly that it made Lin Zhixia feel very good.
The dark clouds in the sky dissipated, snowflakes were flying in the air, and the faint sunlight illuminated the entire teaching building.
"Let's go, it's time to go home," Lin Zhixia suggested, "My dad is almost at the school gate, and your driver is waiting for you."
Jiang Yubai said nothing. He opened his umbrella again and walked ahead. His and Lin Zhixia's backs gradually blended into the misty snow scene.
The preliminary examination results for the 2005 competition class will be released in March.
Lin Zhixia became the well-deserved first place.
In that exam, she scored full marks, including the 10 points for the additional questions, a total of 110 points. Jiang Yubai scored a little worse than her, with 84 points, but he also entered the re-examination without any suspense.
Lin Zhixia happily announced the good news at home.
It was dinner time. After hearing her words, Lin Zeqiu's throat suddenly became dry and he lost his mind in a trance.
110 points
She scored 110 points
Lin Zeqiu had never heard of any student who could score 110 points on a math test in the competition class.
It was as if his soul had been sucked out by someone, leaving him a walking corpse. His mind was blank, and his sister called him several times, but he didn't hear.
His deliberate indifference and neglect ignited Lin Zhixia's anger.
Lin Zhixia asked: "Brother, why don't you pay attention to me? If you ignore me again, I will be angry!"
My brother took two bites of rice and said coldly, "I'm full."
His mother asked him, "Qiuqiu, you usually eat two bowls of rice, why did you only eat one bowl tonight?"
My brother didn't answer. He stood up, walked to his bedroom, and closed the door with a snap.
There was a desk calendar hanging behind his door. He flipped through a few pages and realized that there were only three months left of his peaceful junior high school life. And his highly respected class status also had only three months of shelf life left.
This is a harsh world, and he is about to be baptized by the storm brought by fate.
For several nights after that, Lin Zeqiu had nightmares.
He always dreamed that Lin Zhixia held a loud speaker and shouted at the gate of the Provincial No. 1 Middle School: Attention all students! Attention all teachers! Lin Zeqiu is my brother! I often help him with his homework! He can stay in the gifted class and rank in the top ten in the grade! It’s because I teach well! I treat my brother as my student!
In the following half month, Lin Zhixia would occasionally sneeze for no reason. She suspected that someone was talking about her all day long, but she didn't know her brother's inner struggle.
As the weather gradually warms up, the sun becomes brighter and brighter, the trees on the roadside sprout new buds, and the bustling city becomes more full of spring.
Lin Zhixia happily participated in the retest of the competition class and stood out again. She also made a surprising statement in the interview in May, which made the three judges applaud her in unison.
At that time, the teacher talked to her about a math problem about mixed probability distribution. Lin Zhixia noticed that the variables in a scenario were independent of each other, so she kept three non-intersecting groups, introduced the Chernoff inequality, further narrowed the probability range, and solved the final algebraic expression on the blackboard.
Among the more than 140 candidates, no student's thinking was more agile and sharp than hers.
The teachers were amazed: "What a great talent!"
Lin Zhixia responded with a smile: "Thank you, teacher."
The order of this round of interviews was based on the students' initials in pinyin. Jiang Yubai's interview was over. When Lin Zhixia walked out of the classroom, she secretly glanced at the score sheet in the teacher's hand. She saw that Jiang Yubai's score was A, which was obviously at the upper level of the interviewees.
She finally felt relieved.
Sure enough, Jiang Yubai is a very outstanding boy!
When the final results were announced, Lin Zhixia ranked first with a total score of 117.8, far exceeding the second place by more than 30 points.
Jiang Yubai ranked 16th and was successfully selected into the competition class. He glanced at his score and it was really average. But he still received unanimous praise from his parents and uncle. His uncle praised him for three days in a row, saying that Jiang Yubai was a leader among people, skipping two grades at a young age, not arrogant or impatient, and had a deep mind. His future was limitless, and he was worthy of being the nephew carefully cultivated by his uncle.
As for Jiang Yubai and Lin Zhixia’s arch-enemy, Duan Qiyan, his total score ranked third.
Lin Zhixia scored more than 50 points higher than Duan Qiyan. She looked at his score and sighed slightly. What can she do? The die is cast and it is hard to reverse it.
With a compassionate heart, she will destroy Duan Qiyan's good reputation.
She remembered that Duan Qiyan was a sixth-grade student at the Normal School Attached Primary School. He had been in school for six years and always ranked first in exams, earning him the nickname "No. 1 God of War".
"The No. 1 God of War in the Normal School Primary School" is such a silly name.
Jiang Yubai almost forgot about Duan Qiyan.
Jiang Yubai's daily life is very fulfilling. Under the care of his parents and many tutors, he has grown up healthily and vigorously. Especially since the beginning of spring, his height has grown even faster. In June, he changed his pants and shoes again. His mother said with great satisfaction: "According to this growth trend, you will be as tall as your father when you grow up."
Grow as tall as his father—this is one of Jiang Yubai’s wishes.
His father even teased him: "Jiang Yubai is better than me. When I was ten years old, I never thought about skipping a grade."
Mom chuckled: "You are not bad now. Like father, like son."
Dad and Mom were originally sitting on the sofa. Dad suddenly leaned over and whispered in Mom's ear. He also raised one hand to straighten the diamond necklace around his wife's neck. His wife blushed slightly and whispered, "Jiang Yubai is still here."
Jiang Yubai didn’t quite understand.
Does it make any difference whether he is here or not
Dad said gently, "Go review your lessons."
"I just came out of the study." Jiang Yubai stated.
"Very good," his father praised him, "You just reviewed your lessons. Go to the martial arts training ground to exercise your body. A healthy body and mind are what makes a real man."
Jiang Yubai felt that his father's words made sense, so he changed into sportswear and went to the martial arts training ground at home alone.
It was a peaceful Sunday afternoon, the sun was shining, the sky was bright, and the breeze brought the fragrance of early summer flowers. Jiang Yubai ran half a circle around the martial arts training ground, and suddenly remembered what Ding Yan had said... He was tired of Taekwondo and was preparing to learn tennis. Ding Yan also signed up for the "Children's Tennis Crash Course" this summer.
Jiang Yubai is about to enter junior high school. He cannot graduate with his friends Ding Yan and Dong Sunqi.
He decided to prepare a small gift for those classmates.
On Monday morning, Jiang Yubai, carrying his schoolbag and handbag, stepped into the classroom of Grade 4 (1) of Experimental Primary School.
Not long ago, the last final exam for the fourth grade was over, and today was the day for the students to collect their scores. The head teacher had not yet appeared, and the classroom was noisy and noisy.
Jiang Yubai walked around to Ding Yan's seat, took out a tennis ball and a racket from his bag, and placed them on Ding Yan's desk. Ding Yan opened his mouth in surprise, but before he could say anything, Jiang Yubai left.
Jiang Yubai came to Dong Sunqi's seat again. He gave Dong Sunqi a copy of Business Records and Supply Chain Management and said, "You often lend things to your classmates. Supply Chain Management is the best book for you."
Finally, Jiang Yubai returned to his seat and gave Lin Zhixia the "Jiang Shaoqi Violin Solo Genuine DVD Disc". He said uncertainly: "You seem to like music very much."
"Yes!" Lin Zhixia admitted, "Ever since you taught me how to play the five-line notation last time, I've really liked instrumental music."
Jiang Yubai thought to himself that he had never taught Lin Zhixia at all.
Lin Zhixia grabbed the disc and asked him shyly, "I, I thought you prepared parting gifts for your friends, why did you give me another disc? I was in the same class with you in junior high school, just like the comic book "Exploring the Universe", we will never be separated."
Lin Zhixia often said "Jiang Yubai is my good friend". When Jiang Yubai brought gifts to Ding Yan and Dong Sunqi, he felt embarrassed to leave out Lin Zhixia's gift. He covered it up by saying, "Before I left this morning, I took an album of my uncle's."
"Is your uncle the principal violinist?" Lin Zhixia lowered her head and read the introduction.
Jiang Yubai said inexplicably: "I can play the piano."
"I know," Lin Zhixia looked up at him, "You play the piano very well..."
Before she finished her sentence, the monitor Dong Sunqi suddenly stood up and announced to the whole class: "Students, students of Grade 4, Class 1!"
Dong Sunqi walked up to the podium while speaking: "Everyone should have heard that Lin Zhixia and Jiang Yubai were admitted to the competition class of the Provincial No. 1 Middle School. They will enter junior high school next semester. Today, while all of us are here, I, Dong Sunqi, as the class monitor, would like to take the lead in applauding Lin Zhixia and Jiang Yubai!"
The applause in the class lasted for a long time.
Dong Sunqi raised his hands high and grasped his palms backwards: "Alright! Everyone, hold it in! Give squad leader Dong some face!"
The whole class immediately quieted down.
Dong Sunqi talked eloquently: "Lin Zhixia has been in our class for four years, and she ranked first in the grade in the overall exams. She has won so many honors for our class! She is the material for the provincial No. 1 middle school competition class! Jiang Yubai has been in our class for a year, and he is also my good brother! I will remember his "Exploring the Universe" series for the rest of my life! Today, as the class monitor, I, Dong Sunqi, will take the lead in cheering for Lin Zhixia and Jiang Yubai!"
There was constant applause from below the podium.
Tang Leqin, the deputy monitor, suddenly stood up and expressed her opinion: "Jiang Yubai's "Exploring the Universe" has no ending."
"There is an ending!" Lin Zhixia immediately raised her hand, "There is an ending!"
Dong Sunqi slapped the desk and said, "What's the ending? Tell me now!"
The whole class concentrated and listened attentively.
Lin Zhixia summarized: "We have all embarked on different paths. We are constantly exploring the unknown universe. No matter what the future holds, the students of Class 1, Grade 4 will always be young and determined."
"It's a happy ending," Dong Sunqi unilaterally concluded, "We have companions and things we want to protect."
He opened his arms, immersed in the comic plot: "Long live Orion!"
Half the class responded.
Jiang Yubai stood up and shouted: "Long live the Earth!"
The other half of the class responded immediately.
Lin Zhixia saw someone outside the window out of the corner of her eye. She looked sideways and found Teacher Wu standing outside. Teacher Wu had come a long time ago, but she didn't come in. She waited until Dong Sunqi finished all the nonsense before gently knocking on the front door of the fourth grade (one) class.
Only then did Lin Zhixia realize her gentleness.
This kind of tenderness is not common, and Lin Zhixia was a little distracted.
Teacher Wu came and left quickly. She assigned homework and told the students to be safe during the summer vacation. Finally, she simply praised Lin Zhixia and Jiang Yubai and let the whole class go home.
The summer vacation for the fourth grade officially began.
The students left the classroom one after another.
The sun was shining brightly in the corridor, making everyone feel warm. The boys were discussing the space war with great interest. The class monitor Dong Sunqi suddenly said, "Hey, when school starts next semester, we won't be able to see Lin Zhixia and Jiang Shoufu anymore."
Dong Sunqi's deskmate Wei Rongjie shook his head and sighed: "The two people in this class who read more than me are leaving. There is no place for readers in the class anymore."
Deputy monitor Tang Leqin's sadness was more obvious: "I miss Lin Zhixia. I just found out she's really cute."
Gan Shuli said blankly: "Me too."
Ding Yan held the tennis racket, with a layer of dark clouds around him: "Damn, I'm about to cry." He turned his head to look at Jiang Yubai and shouted: "Jiang Yubai! We are still friends! I will come to play with you later!"
Jiang Yubai waved at him.
In the stairwell on the fourth floor of Experimental Primary School, the shadows of Jiang Yubai and Lin Zhixia were stretched long by the sunlight. They walked over the stairs one after the other, and parted ways with many of their primary school classmates.
The students all recalled what Lin Zhixia had just said.
She said: We have all taken different paths. We are constantly exploring the unknown universe. No matter what the future holds, the students of Grade 4 Class 1 will always be young and determined.
This is the ending of "Exploring the Universe", and it is also the ending they all agree on.
