Tsinghua campus is very big.

To what extent. Take chestnuts for example. If you want to visit the whole campus of Tsinghua University, one day is not enough!

Fortunately, the location of Cheng Nuo's dormitory is not far from the registration place.

On the way, Xu Lang and Cheng Nuo introduced the buildings in Tsinghua campus. After about ten minutes, he sent Cheng Nuo to the dormitory.

"Well, this is your dormitory. It was built this year. If there is no accident, you will live here for four years. Of course, studying abroad is an exception. " Xu Lang introduced Cheng Nuo.

Cheng Nuo looks up.

Brand new dormitory building, seven floors, about 20 dormitories on each floor.

See Xu Lang turn to want to go, Cheng Nuo mouth says, "schoolmaster, do not go up together with me?"

"No Xu Lang's footsteps stopped, and his mind could not help but recall the tone of Cheng Nuo's saying that "senior students belong to younger students". Chrysanthemum was inexplicably tight and sneered. He waved to Cheng Nuo and left in a hurry.

"How did you run?" Cheng Nuo is at a loss.

Cheng Nuo walks into the dormitory with his suitcase.

"203, this is it." On the second floor, Cheng Nuo walks to the door of No. 203 dormitory and gently opens the door.

There are already people in the dormitory.

Inside and outside the door, four eyes are opposite.

The man got up slowly, staring at Cheng Nuo.

"Cheng Nuo?" The man had an excited tone.

"Who are you?" It's still a familiar prologue.

"I'm Yuan Hua!"

At this time, a sad music sounded.

Snowflakes are flying ~ ~

the north wind is howling ~ ~

the world is vast ~ ~

"sorry, I call." Yuan Hua made an apologetic gesture to Cheng Nuo and answered the phone, "Hello, mom, yes, I've arrived at school Well, all the roommates are here Mom, guess who I saw? It's Cheng Nuo! Uncle Cheng Nuo!! I said, this year's college entrance examination champion, I adore him! I didn't say to you that I was determined to be Cheng Nuo's man Mm-hmm. that's it. Hang up. "

Yuan Hua hung up the phone and looked at Cheng Nuo, who was still standing outside the dormitory door. He was embarrassed and said to Cheng Nuo, "come on, Cheng Nuo, please come in, please!"

Cheng Nuo walks into the dormitory with his suitcase and looks at the environment in the dormitory.

Standard room for four, bed and table. There are balconies, toilets, central air conditioning.

Due to the new dormitory building, beds, desks and so on are brand-new.

All in all, not bad!

"Cheng Nuo, is it really you?" Up to now, Yuan Hua still doesn't believe Cheng Nuo appears in front of him.

Besides, he was his roommate.

In this way, from him to become Cheng Nuo's man, a step further.

After all, you get the moon first!

Cheng Nuo took his things out of the trunk and said with a smile, "otherwise?"

"I heard that you were admitted to Tsinghua University. I thought you went back to the Department of mathematics, but you came to the Department of finance first!" Yuan Hua sat on his stool, sighed and then asked, "by the way, Cheng Nuo, I heard that your college entrance examination mathematics is the only full mark in China. Why not go to the mathematics department?"

"Sister There is no academic atmosphere. " Well, Cheng almost let slip.

"No academic atmosphere?" Yuan Hua scratched his head in confusion.

As far as he knows, Tsinghua's mathematics department is one of the most academic departments.

"Cough!" Cheng Nuo coughed and changed the topic, "by the way, where are the two of them, haven't come yet?"

Cheng Nuo said, of course, their other two roommates.

"Oh, this one." Yuan Hua said, "the two of them have come long ago. Now they go to the school store to buy thermos bottles and washbasins. By the way, Cheng Nuo, did you bring these things? If not, I asked them to bring a set back for you. In terms of time, they should have just arrived at the mall

"Bring me one."

…………

Twenty minutes later

Cheng Nuo's other two roommates, one with a lot of things into the dormitory.

"Sister, I'm so tired with so many things!" A chubby boy with a weight of at least 250 Jin put a lot of things on the ground, and then sat down on the stool, panting.

"All right." The other is a boy with brown black skin and curly black hair. His bulging biceps shows his strength.

"This school is too big. It takes more than ten minutes to walk to the shopping mall nearest to our dormitory." The little fat man still complained, "if I had known, I would not have come to Tsinghua! Taitemaokeng you fat

"All right, all right. Don't talk about it. Since all the people in our dormitory are here, let's get to know each other first. " Yuan Hua clapped his hands to attract the attention of the other three."I'll go first." Yuan Hua was the first to introduce himself, "Yuan Hua, from eastern Guangdong Province."

"Zhongjian, from Hutun." The little fat man took out a bag of potato chips and ate them crunchy, looking at Yuan Hua.

"Cheng Nuo, from Dongshan province." Cheng Nuo introduces himself with a smile.

Finally, the brown and black boy said, "I'm from Xinjiang, Uyghur nationality, and my name is Maimaidi naransebast gilnur amqi!"

Cheng Nuo's three people:

Big brother, are you sure, what you said is the name?

"Er That what? Can you say that again? " Cheng Nuo speaks slowly.

"I know you can't remember. To tell you the truth, my name is long in our Uighurs. Just call me T-Mac. " McGrady shrugged and laughed.

"Then we'll call you Tracy." The three agreed.

"Come on, eat the chips, eat the chips." Zhong Dun, a little fat man, handed the chips to the others.

The other three each grabbed one. When he took the chips back, his hand shook carelessly, and one of them fell to the ground.

The little fat man is stunned. When he wants to throw the potato chips on the ground into the garbage can, he is stopped by Cheng Nuo.

"Why don't you eat it?" Cheng Nuo points to the potato chips in the little fat man's hand and asks.

The little fat man's face was muddled, "it fell to the ground, dirty ah!"

Cheng Nuo serious, "who said, potato chips fall on the ground, is dirty."

"Isn't it?" The little fat man continued to be confused.

Cheng Nuo shook his head, a faint smile, "then I ask you, the shape of potato chips, is it a curved surface?"

Little fat man's math is still good, otherwise he won't be admitted to Tsinghua University. He nodded, "yes."

"Is the ground a plane?" Cheng Nuo continued.

The little fat man continued to nod.

"A curved surface, in contact with a plane, is it a tangent contact?"

"Tangent contact means that two faces actually intersect on one line. The area of a line on the two-dimensional plane is equal to zero. Right? "

"Is a potato chip dirty on the floor? Dirty, dirty how much, dirty a line, a line area is how much? Equal to zero! So, he's not dirty! "

"Even if it's upside down or vertically inserted on the ground, it's the same. It only intersects a line with zero area!"

Cheng Nuo shrugged and made the final conclusion, "so for potato chips, which are curved in shape, no matter how they fall on the ground, they will not be dirty. If you pick it up, you can still eat it. "

"I call this theorem Tangent edible theorem! "

The little fat man took the potato chips that fell on the ground and looked at Cheng Nuo.

I don't read much. Don't lie to me!
