whatever you do

After Christmas, New Year's Day is just a few days away.

Although it's the final season of the semester, the wave is still worth it. Anyway, if you study for one more night, you won't get full marks in the exam.

Fu Zhe didn't go home, so it was the first time for the four of them to spend New Year's Eve together.

We had a hot pot meal first, and we went lively until ten o'clock, and then we went to play board games together.

Shi Jiayang always lost in the first few rounds, so he called Xie Ran over. After all, Xie Ran can beat him by playing board games.

"Didn't you go to New Year's Eve with your friends?" Fu Zhe asked when he saw Xie Ran coming over.

"Go, I just slipped out of the KTV." Xie Ran sat down beside him after speaking.

"Hey, Xiao Ranran, I asked you to help, why are you sitting next to Sha Zhe?" Shi Jiayang asked him.

"You don't have to sit by your side to help, don't worry, I will definitely choose you as my partner." Xie Ran said with a smile, "I will take you to win."

"Don't talk too early, kid, there's me and Xiaotu." Ye Shu said calmly.

"If I lose, I will pay the bill today." Xie Ran showed a provocative smile.

At first, it was Ye Shu and Gu Nianchen against the three of them, and later it gradually became Ye Shu and Xie Ran, because they were the only ones left in the game.

At twelve o'clock, someone in the store shouted "Happy New Year", Ye Shu heard it and put down the cards in his hand.

"That throws me in the towel, happy new year."

Xie Ran also put down his cards, "I should have lost, happy new year."

"Happy New Year, congratulations to everyone who has struggled for another year." Fu Zhe said with a smile.

"Happy New Year, come, come, let's take a group photo." After finishing speaking, Shi Jiayang ran to the front desk and handed his mobile phone to the young lady.

"One, two, three, okay, one more."

"Fatty really has stones again." Ye Shu looked at the circle of friends that Shi Jiayang had just posted, and complained.

"What do you mean?" Shi Jiayang asked.

"Come on, let's rock-paper-scissors." Ye Shu didn't answer directly, but said so.

Shi Jiayang played a game with him suspiciously, Ye Shu was cloth and he was stone.

"That's it." Ye Shu spread his hands, and took a sip of juice.

"Ah?" Shi Jiayang was still confused, and Fu Zhe and Xie Ran didn't quite understand what Ye Shu meant.

"Teacher Gu, do you understand?"

Gu Nianchen smiled helplessly, and then explained: "Xiaoshu is saying that you are lazy, because you often punch, and you are too lazy to stretch out your fingers for scissors or cloth."

"I admire." After hearing this, Fu Zhe clasped his fists together, "You two are so amazing!"

"I can't see that Senior Shu will hurt people so much." Xie Ran extended his thumb to Ye Shu.

"Then what does this have to do with my circle of friends?" Shi Jiayang still didn't understand.

"Because you didn't retouch the pictures." Ye Shu explained, "Look at the two pictures you posted, no one can see them except Xiaotu."

"Who told you to close your eyes, who made Shazhe turn his head, and who told Xiao Ranran not to look at the camera?" Shi Jiayang retorted angrily, "If I was lazy, I wouldn't post it."

"Well, you are not lazy, you are the most diligent." Ye Shu quickly changed his words.

"So, shall we continue playing now?" Xie Ran asked.

"Little Tu, are you sleepy?" Ye Shu asked Gu Nianchen.

Gu Nianchen smiled and shook his head, "Not sleepy."

"Okay, let's continue playing." Ye Shu said.

The five people played until two o'clock, Ye Shu and Xie Ran didn't know who won, and the two competed to pay the bill, but Fu Zhe snatched it away.

When I walked out of the store, Fallen Street was still very lively, and there were quite a lot of pedestrians on the street.

"Let's go watch the sunrise!" Ye Shu said suddenly, "It takes about three hours to walk to the river from here, and the sunrise is around [-]:[-]."

"Okay." Fu Zhe replied with a smile, "Let's cross half of City S!"

"Walking?" Shi Jiayang asked.

"Yes, could it be that you want to take a taxi?" Ye Shu said calmly, "The subway is long gone."

"Otherwise, Jiayang, why don't you go back to sleep? I'll take a picture for you." Xie Ran patted Shi Jiayang.

Shi Jiayang was silent for a few seconds, then said melancholy: "Then can you walk slowly, when I can't walk, you take turns to help me down?"

"We can take turns carrying you." Ye Shu nodded.

"That's fine, let's go! Sunrise, riverside, here I come!" Fatty Shi yelled twice.

The five of them left as soon as they said they wanted, talking and laughing all the way, and complaining about the final exam together, but they didn't feel bored.

Fatty Shi talked about his own embarrassing things, Fu Zhe told his parents' love story, Xie Ran talked about his journey to stardom, Ye Shu and Gu Nianchen were pestered by Fatty Shi to tell about their childhood.

When we arrived at the riverside, it was just six o'clock, it was still dark, and there were several oil tankers floating on the river.

"I didn't expect that I would walk so far, ten kilometers! A full ten kilometers!" Shi Jiayang said weakly on the railing: "But I'm really tired."

"Congratulations on breaking through yourself and achieving new achievements." Ye Shu smiled and patted his head.

"Can I hug Teacher Gu?" Shi Jiayang asked grimly.

"No." Ye Shu replied blankly.

Gu Nianchen smiled, walked over and hugged Shi Jiayang, and patted him on the back.

"Ah, I'm dead! I've earned it, Teacher Gu took the initiative to hug me!" Shi Jiayang seemed to be fully charged, and jumped on the spot twice.

"Promise." Fu Zhe glanced at him.

As soon as Fu Zhe finished speaking, Xie Ran hugged him, he reacted and pushed him, Xie Ran stopped him and let go of him.But before he let go, he leaned into his ear and whispered something.

"So, Xiao Ranran, are you and Sha Zhe together?" Shi Jiayang asked curiously.

"No, I don't accept brats." Fu Zhe said coldly.

"Soon." Xie Ran hugged Fu Zhe's shoulder with a smile, but Fu Zhe knocked off his hand in the next second.

Ye Shu smiled and said nothing, and held Gu Nianchen's hand.

The sky gradually changed from black like thick ink to gray mixed with a lot of water, and then the skyline showed a little orange.

Immediately afterwards, that little bit of orange slowly diffused, and the color gradually deepened, revealing a small round spot of light on the distant river.

"Ahhh~" Shi Jiayang suddenly yelled at the river, "Sun~"

The four looked at him and smiled in unison.

"Sunshine~" Ye Shu also called out, "Warm~"

"Sky~" Fu Zhe also joined, "Freedom~"

"Flowers~" Xie Ran also shouted with a smile, "Love~"

Ye Shu looked at Gu Nianchen and showed him a bright smile, Gu Nianchen smiled.

"Starry Sky~" he tried to shout, "Hope~"

"Go to hell with the final exam!" Shi Jiayang continued to shout.

"Fu Zhe, I like you~" This is Xie Ran's voice.

"Xie Ran, I don't like you~" This is Fu Zhe's voice.

"You have already lost~"

"You didn't win either~"

"I won't give up~"

"Then just wait~"

Ye Shu pulled Gu Nianchen to watch the sunrise with a quiet smile, listening to Xie Ran and Fu Zhe shouting in turn, Shi Jiayang interrupted occasionally.

"Silly, please promise Xiao Ranran~"

"Xiao Ranran, you like me, don't like silly Zhe~"

When the sun jumped out completely, the sky was completely bright, and the warm sunlight shone on them.

I didn't feel tired after not sleeping all night, but I was extremely excited.

Shi Jiayang even suggested walking back to school, Ye Shu and Fu Zhe slapped him alone.

Ye Shu hailed two cars, thinking that Xie Ran would go back to the community with them, but Xie Ran said he was going to send Fu Zhe back to school, so Ye Shu and Gu Nianchen left first.

"Are you sleepy, do you want to take a rest?" Gu Nianchen asked Ye Shu gently.

"It's okay, just hold it for a while."

Ye Shu had one general exam left, and on January [-]th, Gu Nianchen had three exams left.

"During the winter vacation, come home with me." Gu Nianchen asked while hugging him.

Ye Shu was silent for a while, then buried her face in his neck, and muffled, "Okay."

After the final exam, Fu Zhe went home to live, but he often came to play with Gu Nianchen, and Shi Jiayang had the cheek to eat and drink.

"Mr. Gu, why are you still reading during the holidays?" Shi Jiayang slumped on the sofa with a bag of potato chips in his arms.

Gu Nianchen smiled at him, but didn't speak.

"Eat yours, don't talk." Fu Zhe answered, and then picked up a book to read.

In fact, in November of this semester, Ye Shu took Gu Nianchen and Fu Zhe to sign up for the Meisai (American College Students Mathematical Contest in Modeling). The competition was more than ten days later, and the three of them had no experience, so now Read some books to quickly supplement knowledge.

In the early stage of the competition, Ye Shu wanted to drive Shi Jiayang away, but Shi Jiayang vowed that he would be absolutely useful.

Ye Shu thought that his English was not bad, at least the translator could help, so he allowed him to stay in the house.

The competition lasts for four days. Questions are released at 1.25:1.29 am on [-] and submission is due at [-]:[-] am on [-].

Since none of them majored in mathematics, they directly gave up the three courses of MCM and planned to choose from ICM.

Both the test questions and the final paper are required to be in English, and it took the four of them nearly three hours to figure out questions D, E, and F.

"I think both D and E are fine. F is too open. It is hard to find data and literature, and the fifth question is purely Chinese modeling." Ye Shu said, "What do you think?"

"I also feel the same way. In the privacy market, how much money you are willing to spend to sell your privacy. This modeling is pure fantasy. Although it is very interesting, it is really difficult to do." Fu Zhe replied,

"I think it's all right. Although there is no precedent for purchasing personal privacy, you can consider the influencing factors and program it yourself." Gu Nianchen said, "But obviously D and E are better, and the data and algorithms are readily available."

"It must be a good choice, D and E, one." Shi Jiayang yelled, "I don't understand what this F is talking about, and what I want you to do."

"Okay, then choose one of the two, the word is D, and the flower is E." After Ye Shu finished speaking, he tossed a coin.

"God let us choose D, friends, come on!"

"Well, why don't you go eat first? It's already twelve o'clock and I'm hungry." Shi Jiayang raised his hand weakly.

"Sure." Ye Shu nodded.

In the afternoon and evening, I hardly did anything substantive. I kept looking for data, but I couldn't find it.

"Otherwise, let's call Tesla directly and ask how many charging stations they have, and what is the efficiency of different charging stations?" Fu Zhe said weakly.

"Do you think someone will tell you?" Ye Shu lazily replied, "We still think too simply."

"That's right, we will make a plan later to promote the proportion of electric vehicles from 0% to 100%, and choose Ireland, South Korea or Uruguay." Fu Zhe continued, "Even if we really come up with a plan, will it work? Not at all. Will someone implement it?"

"Australia, Indonesia, Singapore, etc." Ye Shu said helplessly, "Let's do this for today, we'll talk about it tomorrow."

As a result, the data was still not found on the second day. Ye Shu thought that they should not be allowed to compile the data. Gu Nianchen suggested that the required data could be assumed to be letters, for example, the city population is p.

So they barely solved the first task, how to allocate charging stations and charging piles between cities and rural areas.

On the third day, the four of them discussed it all morning, but they couldn't figure out what to do in the end.

"I wonder if Tesla has invested in sponsorship, let us find ways to expand it." Fu Zhe said mockingly.

"We also paid the registration fee, $100." Ye Shu said with a smile.

"I just want to have a good New Year now, why should I stay here?" Shi Jiayang said lying on the table.

"Mr. Gu, do you have any ideas?" Fu Zhe looked at Gu Nianchen.

"I think AHP and infectious disease models can be used, but I don't know how to use them." Gu Nianchen said lightly.

"I know hierarchical analysis, what is the infectious disease model?" Ye Shu asked.

Gu Nianchen found a book from the side, turned to a certain page and handed it to him.

Ye Shu looked at it for a while, then nodded, "I think it can be used too."

In the end, the three of them started brainstorming, saying whatever came to mind, and writing it down. Shi Jiayang listened to it for a while, and then started to watch it again and again.

At the end of the day, I finally had some ideas. Although the model hadn't been built and the thesis hadn't been written, I wasn't panicking at all.

The author has something to say: Xiaoshu: Why do we have to participate in this bald competition during the winter vacation?

Stupid author: Because I used to be bald, I want you to be bald too (hahahaha, insane laughter)
