Chapter 290

"Professor Lu, I have no opinion. Cheng Nuo shrugged with a smile.

Professor Lu nodded, "Okay, in that case, I'll report your name." ”

"And. Professor Lu continued, "All students in our school who sign up for this mathematics competition will have a unified training camp before the competition. ”

"The specific training time has not yet been decided, but according to the practice of previous years, it should be held after the year. You have a mental preparation in advance, and I will inform you when the time is arranged. ”

Cheng Nuo breathed a sigh of relief. The training camp after the year is better than the winter vacation training camp.

"In addition, during the winter vacation, Cheng Nuo, don't let up. Professor Lu reminded Cheng Nuo, and then picked up a stack of test papers from the desk, looking at the thickness, there are at least a dozen sets, "These are the test questions of the group of freshmen and sophomores in previous years, both non-mathematics majors and mathematics majors, if you have time during the winter vacation, you can do them all again." ”

"Thank you, teacher. Cheng Nuo accepted Professor Lu's "kindness".

The difficulty of the competition questions is not comparable to the usual questions. Just like the three finale questions that Professor Lu asked Cheng Nuo to do some time ago, Cheng Nuo will only do one.

Of course, those three questions were the finale of the third and fourth grade groups, and Cheng Nuo did not learn a lot of knowledge. Cheng Nuo can only sign up for the mathematics competition in the first and second grade groups, and as for the competition in the third and fourth grade groups, even if Cheng Nuo wants to participate, he is not eligible.

But no matter what, Cheng Nuo still has to prepare for the war with all his might.

The scope of the competition is not limited to Cheng Nuo's current freshman year, including high generation, solution, and counting. The complex variable functions and ordinary differential equations that will be studied in the sophomore year account for a lot of points in the competition papers.

Therefore, during the winter vacation, Cheng Nuo also needs to find time to complete these two courses by himself.

............

On January 27, Cheng Nuo took the last political economy exam of the semester.

An hour later, Cheng Nuo walked out of the examination room with a relaxed expression.

At this point, the first half of Cheng Nuo's freshman year officially ended and entered the winter vacation stage.

On January 27th, the fifteenth day of the lunar calendar, there is still exactly half a month before the New Year. Generally speaking, college breaks are a few days earlier than high school. If it drags on for a few more days, the congested station will definitely make you doubt your life.

Cheng Nuo bought a ticket for tomorrow. and Mu Leng and Su Xiaoxiao went home together.

The arrangement of the Peking University School of Mathematics, where Mu Leng is located, is almost the same as that of the Tsinghua School of Mathematics, and all the examination subjects have been completed as early as three days ago.

And Kyoto Normal University, where Su Xiaoxiao is located, will not end the exam week until tomorrow morning.

Evening, 203 dormitories.

A few people bought some side dishes from the roadside stalls, and went to 7-Eleven behind the dormitory building to buy a few bottles of canned beer, and they were so excited that they fell asleep in the middle of the morning before they said goodbye to each other.

When he woke up in the morning, he and the little fat man were the only ones left in the dormitory.

There are four people in the dormitory, and only Cheng Nuo is relatively close to home. The other three, Maddie in Xinjiang, Yuan Hua and Little Fat Man, one in Guangdong Province, and the other in Hu Jian, are all the kind that take a day and a night by train.

"When did the two of them leave?" Cheng Nuo rubbed his head and asked the little fat man who was holding chicken legs under the bed and gnawing on them.

The little fat man wiped the oil on his mouth, "They left at six o'clock, and they didn't call you when they saw that you were sleeping soundly." ”

Cheng Nuo turned over and sat up, "Then why aren't you in a hurry?"

The little fat man looked serious, "I still have a wish that has not been fulfilled." I must fulfill this wish before I go back. ”

Cheng Nuo saw that the little fat man looked a little shy, and asked curiously, "Is your wish...... Say goodbye to virgins, can you add me one?"

"......" little fat man: "Get out, Cheng Nuo, am I such a cheesy person?"

He shook his phone and said to Cheng Nuo excitedly, "The weather forecast says it will snow today?"

"Snow?" Cheng Nuo suddenly said.

Only now did he remember that the little fat classmate was an authentic southerner, and he was curious and yearning for snow, a matter that only existed in legends.

Originally, the little fat man thought that after coming to Kyoto, he would have the opportunity to see the snow scene in the north, but he didn't expect that God was not in a recession this year, and until now, there has not been a snow in Kyoto.

However, according to the weather forecast, Kyoto will receive snow today.

Although the weather forecast is as unreliable as Cheng Nuo, the little fat man still retains his last hope and waits silently and religiously.

"The weather forecast must be accurate this time!" the little fat man whispered to himself.

To be honest, as a northerner, Cheng Nuo didn't understand the mood of the little fat man at this time. He glanced out the window, the data flowing in his eyes.

Air quality 15, air temperature -5 degrees Celsius, UV index 3, air humidity 100% ......

Cheng Nuo smiled, "Don't worry, it will definitely snow today." ”

Cheng Nuo was on the plane at two o'clock in the afternoon, and he was not in a hurry, so he was waiting for the snow with the little fat man while packing his luggage in the dormitory.

"It's snowing!!"

Suddenly, a roar of surprise came from downstairs in the dormitory.

Immediately afterwards, the entire dormitory building was in a state of stagnation and gradually boiling.

The little fat man also sighed and disappeared from the dormitory.

Cheng Nuo ran to the balcony, opened the window, and a cold air hit his face. Looking up, the flickering sky was filled with goose-feather snowflakes. The floor has been covered in silver.

Downstairs, the men from the south were in tears and looked fascinated.

The little fat man mixed in the crowd, running excitedly, laughing like a fat man of more than 200 pounds. Belch...... No, he's a fat man of more than 200 pounds.

Snow is the light of life and the fire of desire of southerners.

On a snowy day, southerners look at snow, and northerners look at southerners, and this sentence is really true.

Outside, the snow was getting heavier and heavier, and soon it was piled up to a centimeter or two thick, and it creaked when stepped on.

Cheng Nuo walked downstairs and happened to see the little fat man running upstairs in a hurry. Cheng Nuo grabbed him, "Fatty, where are you going?"

"It's snowing so much, I'll go upstairs and get an umbrella!" said the little fat man as a matter of course.

Cheng Nuo: "......"

Your logic...... No problem!

After explaining for a long time, Cheng Nuo finally let the little fat man who saw the snow for the first time understand that he didn't need to use an umbrella when it snowed.

"Alas, Cheng Nuo, I've heard that snow can be eaten, right?" asked the little fat man, who was from Guangdong Province, habitually.

Cheng Nuo nodded, "It's edible, but it's just ......."

Before Cheng Nuo finished speaking, he saw the little fat man grab a handful of snow on the ground, and now he pinched it in his hand, then stuffed it into his mouth and chewed it full.

"Yes, and a little sweet. The little fat man commented.

"Actually, the iron railings in the northern winter are also sweet. Cheng Nuo said with a smile.

The little fat man retorted, "I don't believe it! how can an iron railing be sweet?"

Cheng Nuo shrugged, "I don't believe you can taste it?"

That's right!

Practice is the only criterion for testing truth. The little fat man walked up to the iron railing and stuck out his tongue......
