Cloud Chaser Cemetery

There is no make-up class in the mountainous area, and the school is on holiday not long after June.

When Tang Yuhui went to the last class, he stood in front of the broken wooden door of the classroom for a long time.

The oxygen on the plateau is stingy, but the sunshine is very generous, always covering the land fiercely and indisputably under various such scenes.

A corner of the morning light shone obliquely on Tang Yuhui, and finally he took a deep breath and pushed open the door.

He has always been very light in his movements, but this time he seems to push too fast.

As soon as they entered the classroom, the students who always looked a little embarrassed because of being dirty looked at Tang Yuhui with extra brave eyes today. Many people raised their heads and stared at the door of the classroom, but Tang Yuhui opened his eyes as usual. Smiling, without saying a word, he opened the tattered textbook and began to talk about the last unit in the textbook.

In Mathematics Wide Angle, the last unit is the pigeonhole problem.

Yesterday when Tang Yuhui was preparing for the class, he found it a little difficult. He looked at the children of different ages crowded in the classroom, and remembered that the youngest one ran over shyly and proudly in the last class and told him that he had just memorized multiplication. surface.

Tang Yuhui really wants to show them a wider and wider world, and also wants to take them there.

But he has no such chance.

In the crowded and dilapidated classroom, the body temperature of Kang Zhe holding him appeared untimely on the sensory layer of the skin. Tang Yuhui thought that he understood earlier than these children that the eternal fact of life is that everyone can only Walk with you for a while.

It's just that he doesn't really want these children to understand such a sad fact.

Tang Yuhui called three students of different ages to come to the front of the podium.

The students were still a little embarrassed, and Tang Yuhui smiled encouragingly at them one by one.

He carefully took out four chalks from the chalk box, stood on the podium and said softly: "Now the teacher has four chalks in his hand and wants to distribute them to three children. Before the teacher divides them, he knows that there must be one of them. Have at least two chalks, do you know why?"

The students in the audience started to commotion. After a while, a boy said in a very low voice, "I seem to understand."

Tang Yuhui smiled, took the chalk and walked up to the three children who were a little nervous, he gave each of them one in turn, took the last remaining one, and held it up in front of his eyes, showing that he and his The students smiled indiscriminately and childishly, and their eyes were bent.

There was a cry of surprise from under the podium.

Tang Yuhui looked at the three children in front of him again. When the oldest one made eye contact with him, he turned his head embarrassingly. Tang Yuhui smiled, walked up to the child, and handed the chalk to the child. in his hands.

"The pigeonhole principle is a basic principle in combinatorics. In fact, it is also called the drawer principle. It was first proposed by a German mathematician. The teacher gave four chalks to three people, and one of them will definitely get it." At least two; similarly, if we put three apples in two drawers, there will be at least one drawer with two apples; if five pigeons fly into four pigeonholes, then there must be one pigeonhole The pigeons here will have another partner, won't they?"

Seeing that some students seemed to have suddenly realized, while others still seemed to be at a loss, Tang Yuhui smiled and put down his hand that wanted to continue writing complex formulas on the blackboard.

The little boy who memorized the nine-nine multiplication table yesterday seemed to be so tangled up that he could catch flies. Probably because of his young age, he was not always restrained like other students. He was very active in class and often Ask Tang Yuhui a question.

This time, he still didn’t seem to understand, so he raised his hand and said in a ignorant way, “Teacher, you told us that there are 34 provinces in China, so there are 35 people in our school including you, right? As long as you fly hard, someone will always see you in another place."

The classroom fell silent for a moment, and the little boy seemed to feel that he had asked a question that had nothing to do with the theorem. At this time, he said timidly as if he had done something wrong: "Is it wrong to say that..."

At this time, the bell rang for the end of get out of class, and Tang Yuhui stood quietly for a while. He really wanted to tell the child the assumptions in mathematics and the reality of the world, and he also wanted to tell them that pigeons might not have such a big choice.

Indeed, if the other 34 pigeons fly with all their strength, there will be at least one province whose coordinates belong to more than two people, but this place may not be Beijing where they are; what is more likely to wait for the future of this group of pigeons is that only one of them Very few people can fly to other nests, and even if they do, they will forget in time the person who assumed the nest for them in a math class.

Tang Yuhui stood quietly for a while. From the beginning, he didn't want to make any parting gestures. He was afraid that his students would cry, and he was even more afraid that he would cry.

He quietly went through the surging emotions one by one, then slowly suppressed them, and smiled softly: "Well, that's right, but the pigeons don't have to fly too hard, because the teacher is in every The provinces have set up nests, no matter where you fly, the teacher can come and see you."

Walking out of the classroom, Tang Yuhui saw Kang Zhe's motorcycle parked at the dilapidated gate of the school, and Kang Zhe was smoking a cigarette against the earthy yellow brick wall.

Tang Yuhui hadn't seen him smoking for a long time, thinking that Kang Zhe had been waiting for a long time, so he walked a little faster.

Sensing his footsteps, Kang Che moved away from the wall he was leaning against and stood up straight, crushing the smoke on a wall brick.

Tang Yuhui saw that he was looking past him and looked back, so he walked towards him and said, "What's wrong?"

Kang Zhe looked at his face for a while, then raised the corners of his mouth: "Aren't you crying today?"

Tang Yuhui was very inexplicable, and defended himself with a little caution: "I haven't, what's wrong? I've worked very hard, I don't want to cry in front of the children."

He was a little wary: "What are you going to do?"

Kang Zhe wore his usual smile again, this time it was a very bright and willful one, like a big boy with crooked eyes, and answered irrelevantly: "Some things will only be late, and will never be absent."

Tang Yuhui was bewildered, but Kang Zhe clasped his shoulders to make him turn around.

After seeing the scene in front of him, the corners of Tang Yuhui's eyes twitched slightly. Before he could react in his mind, the tears that had been shut down for a long time crossed the guidance of his heart and flowed down first.

In a primary school in Xindu Town, Kangding County, Ganzi Tibetan Autonomous Prefecture, Sichuan Province, there are 34 students in total, all dressed in shabby clothes, of different ages and heights, standing in a row, as uneven as a basin.

They are all equally dirty and weak, because of lack of water and poverty, they cannot be given decent ivory towers that can be sheltered.

They are all small, but they don't have the vivid and infinite possibilities of youth instilled by universal values; but they all look at their favorite and most precious teacher ever, timidly, Reluctant and nostalgic, because he brought them the cleanest, most distant and hopeful dream.

But they are still very far away, as if they dare not approach the beautiful moon, like any wandering homesick, looking up at the distant and beautiful light.

Tang Yuhui whimpered a little and waved to them with tears all over his face, and the pigeons flew back in groups, like tired birds returning to their nests, and hugged him tightly.

The sunlight enveloped them gently, allowing this scene to go through countless similar news reports and documentaries that were monotonous and lacking in new ideas. The holy and beautiful grasslands and mountains will always be grateful and remembered.

Sitting on the motorcycle back to the inn, Tang Yuhui was still crying. His tears flowed quietly, and Kang Zhe felt it from the gradually soaked back shirt.

Kang Zhe stopped the car and patted his head helplessly, "Are you still crying?"

The corners of Tang Yuhui's eyes were terribly red, and his nose was wrinkled into a ball, just like the skin peeling from the ultraviolet rays when Kang Zhe first met him for the first few days.

Tang Yuhui frowned in a rare way, very tough, and said sullenly: "Don't worry about it."

Kang Zhe looked at him and smiled, "It's not that I made you cry, Mr. Tang, please tell me some reason?"

Tang Yuhui still said in a low voice: "I must study hard when I go back, earn a lot of money, and then donate it all over."

"Then you should discuss it with my father," Kang Che said with a smile, "he must be very happy."

Tang Yuhui didn't speak. After a while, he didn't cry so badly, and finally calmed down.

Kang Zhe didn't know why, but he was also quiet for a while like him, stood a little further away from Tang Yuhui, and then slowly said: "You are already 23, why are you still talking like this."

"Does this have anything to do with how old I am?" Tang Yuhui asked in puzzlement, "It is only after independence that I am qualified to say such things."

Kang Zhe sighed with emotion, "How should I put it? To some extent, you are really talented."

Tang Yuhui blinked, and Kang Zhe squatted down next to him, "I've always been curious, how can you be so well protected even though you haven't been loved much before?"

Tang Yuhui intuitively felt that Kang Che was definitely not praising him, and wanted to refute, but couldn't find any suitable words, so he could only say sullenly, "I don't know."

He was a little uncertain, and said with a little blankness: "But I think if there is, maybe my sister is protecting me."

Kang Zhe turned his head and looked at him indescribably.Tang Yuhui said lightly: "I thought about it, if my sister hadn't passed away, and my parents still had me, maybe the only person in that family who loved me would be my sister. After all, as far as I know, she is really, very Very, very kind."

Kang Zhe thought about it again, and felt that this was probably true. After all, Tang Yuhui's parents would not love him. If such a non-existent situation really happened, the only source of family affection might indeed be innocence, kindness, and no lack of love. Loving sister.

"Your family's genes are really miraculous. Your parents are astute as hell, and your siblings are very naive." Kang Zhe lay on the grass and said casually, "And you're quite selfless. You can inherit such a great beauty by relying on imagination. kindness."

Tang Yuhui reacted in a daze for a while, not understanding why Kang Zhe started to hold his gun again, and then blinked slowly after a while, "Azhe, are you angry?"

Kang Zhe didn't even bother to turn over, and said lazily, "Why am I angry?"

"You're mad at me for forgiving my sister so easily," Tang Yuhui smiled, "and treating her as my protector. You think my kindness is weak, and maybe you think it's stupid and worthless. "

Kang Zhe looked at him for a while, then lowered his eyes, and said slowly: "Teacher Tang, you have to remember that I believe in Buddhism, and I will never feel that kindness is worthless."

Tang Yuhui smiled happily as if he had caught something: "That's what you think, maybe you're still laughing at me for being stupid. Ah Zhe, that's how you are. You're avoiding problems."

Kang Zhe looked at him expressionlessly for a while, and suddenly felt that it was pointless even to refute, and he didn't understand why he had such a boring conversation with Tang Yuhui.

He nodded, "Well, you're right."

Tang Yuhui choked, then lowered his head, and said after a moment of silence: "Ach, you are tired of naivety and careless dedication, because you find it troublesome to bear these. But Ach, why? You and I are not the same. Same, so many people love you, you grew up like this, but why don't you love yourself?"

"There's no reason," Kang Zhe said after a moment of silence, "I'm always like this."

"Not everyone is like you. Kindness is your talent, but it's just my choice."

Tang Yuhui said softly: "But Ah Zhe, do you know? I haven't really been so naive all the time. I also hated my sister once. Even if I feel that I live in her shelter, it's only recently. Such an idea was born.”

He looked at Kang Zhe lightly and slowly, and said slowly: "Because I think the good things that can happen in a person's life are very limited. When you encounter some things, you have to forgive other things that are brooding. , to be worthy of that beauty.”

"Defeat evil with good," Kang Zhe smiled faintly, and said lightly, "No wonder my parents like you so much. You are really more suitable to be a believer than many Tibetans."

After being silent for a while, Tang Yuhui withdrew his share of loss, and sighed in relief. He had already reached this point, and he was a little bit unbearable, even a little timid, and didn't want to force Kang Zhe to answer him that much. .

"Okay then, it's me..."

But Kang Che interrupted him suddenly, "If you want to know so much, I'll take you to a place tomorrow."

Tang Yuhui was taken aback, "Where are you going?"

He looked down at Kang Zhe, half of Kang Zhe's face was covered by the shadow of the clouds on the hillside, looking very calm and devoid of any emotion.

Kang Che said without any ups and downs: "You will know when you go."

"Let's go, I'll take you to see the ending of kind people."
