When Lin Wanwan returned to the dormitory, it was the night after the game.
Lin Wanwan from their dormitory participated in this competition, but everyone knew that she was basically there to gain experience.
But because she had a fiancé who was a top student in the mathematics department, Chen Tianying was still concerned about how she did in the exam and what questions she chose in the dormitory.
Lin Wanwan could only say: "It's okay, I chose A."
Chen Tianying said "Ah": "Did you choose A? They say A is very difficult! Hey, it will be good for you. With Xiao Chong as your guide, you can go to the first level of the country. Maybe you can get a chance to get a graduate degree, okay?
Bonus points. I have a senior sister who also participated this year. She said her eyes went dark when she saw the question and she couldn’t think about anything else.”
"Then what topic did she choose?"
"c, but I'm not very sure. I'm going to give her a cup of herbal tea now to lower the heat and comfort her injured little heart."
Lin Wanwan smiled: "Haha, well, you Guangdong people have nothing that a cup of herbal tea can't solve. If there is, then two cups."
Chen Tianying smiled: "I'm leaving, bye!"
"Bye-Bye!"
Shortly after Chen Tianying left, Wu Xiangxiang and Yan Yufei both returned to the dormitory. The former looked ugly, as if someone owed her eight million.
After Yan Yufei said hello to Lin Wanwan, she began to take off her braids and change into slippers.
Lin Wanwan looked at Wu Xiangxiang's face and mouthed to Yan Yufei: "What's wrong with her?"
Yan Yufei shrugged, took out her underwear from her clothes and threw it into the washtub, then took out her cell phone and typed.
The next second, Yan Yufei's message came in on Lin Wanwan's WeChat: "Her internship appraisal form has been received, and the SF package is payable on delivery. There is no stamp and no evaluation."
Lin Wanwan: "Ah, is there nothing?"
Yan Yufei: "I knew it would be like this! My senior sister from high school went to an internship before, and she worked for someone else for four months and got nothing. Ah, no, it's still a success. Every time I learn something, I gain wisdom.
Lin Wanwan: "..."
Yan Yufei: "The center over there has stopped stamping interns for a long time. Whoever stamps is responsible. Hey, in some industries, you don't have to enter alone. If you enter, you will be a bully for others! What about you, has your internship appraisal form arrived?
?”
Lin Wanwan: "I don't want that. I mainly want to study, and I don't want to work in a TV station in the future. I'm quite happy. My two trainee teachers are very good. One of them is Wang Lin, the ace variety show editor."
There was another thing Lin Wanwan didn't say. She didn't have an internship appraisal form, but she had a formal internship contract.
Moreover, before leaving, Wang Lin also said that he would take her with him if he had the opportunity in the future, and the two of them even added a private WeChat message.
Yan Yufei: "Haha, I shouldn't ask you. I heard Wu Xiangxiang said that Xiao Chong is a guest of the program group you are following. You have the relationship with the school boss, so you won't suffer."
Lin Wanwan: "Well, she's really quick with her mouth."
Yan Yufei: "Haha, it's not the first day you've met her."
The two were chatting happily on WeChat. Wu Xiangxiang paused and suddenly said: "Are you two talking about me?"
It has to be said that the squid in the melon field is very sensitive to this kind of atmosphere.
Lin Wanwan and Yan Yufei raised their heads and both denied: "Why are we talking about you?"
Wu Xiangxiang looked at Lin Wanwan and asked: "Wanwan, have you received your internship appraisal form?"
Lin Wanwan shook her head: "No, I don't want it."
Wu Xiangxiang said with deep resentment: "That's right. You Bai Fumei can go home and inherit the family business. You don't need all these things."
Lin Wanwan: "..."
The more Wu Xiangxiang thought about it, the angrier he became, but instead of talking to his roommates, he chose to change his clothes and go out for a night run to vent his anger.
As a senior gossip, she knows very well that her private affairs should not be shared too much with others.
Because there is no empathy in this world, speaking out will only make people laugh, just like her habit of making fun of other people's gossip.
After a summer internship, she deeply felt that studying was the happiest thing.
During the night run, Wu Xiangxiang had already made the decision to attack Baoyan.

Life goes by step by step, going to and from the dormitory, teaching building, library, and canteen every day, and occasionally going to Wenting Community on weekends.
During the National Day holiday, Lin Wanwan and Xiao Chong took a flight back to Yongcheng on the night of the 30th.
Lin Wanwan did not go back to Yongcheng this summer because of her internship, and Xiao Chong did not go home because of the training for the mathematical modeling competition, traveling, and filming a program, so it is necessary to spend time with his family on November 1.
After returning to school after the National Day, Xiao Chong received a defense notice from his mathematics teacher.
Generally speaking, being recommended for defense means that you have won an award. If you pass, you will get a national award, if you fail, you will get a provincial award.
Everyone in the dormitory became excited when they learned that Lin Wanwan had been shortlisted for the national competition along with Xiao Chong.
"Wow! Wanwan, you feel so good. Treat me!" Yan Yufei rushed towards Lin Wanwan and wanted to hug her.
Lin Wanwan quickly stepped aside: "Don't hug me, I don't like Lily. Wait until I finish my defense to treat you, and you may not win the award."
"Definitely! With Mr. Xiao Chong taking you flying, Guoyi is already in your pocket!" Yan Yufei said with a smile.
"Hey, I heard a hot search two days ago, what is academic Ji? She got a nature paper from a male Ph.D., and then abandoned her and went to the United States to become a banana. Hahaha, Wanwan, you
It kind of means that."
Wu Xiangxiang had a forced smile on his face, but the sour feeling in his heart was more lemon than lemon, almost turning into lemon essence, and he unconsciously picked up his gun and carried a stick when he spoke.
She was obviously the strongest in this dormitory when she first entered school, but she came in as the provincial liberal arts champion.
But now, first Chen Tianying published a physical book without saying a word, and Lin Wanwan was also shortlisted for the national competition, but she had nothing.
Lin Wanwan looked Wu Xiangxiang up and down, raised her eyebrows and said, "I can't tell, Wu Xiangxiang, your ambition is quite lofty. Do you want to be an academic girl?"
"Ah ah ah, Lin Wanwan! I was just joking, and you took it seriously!"
"so what?"
"Okay, okay, stop talking, harmony! Harmony!" Yan Yufei pushed Lin Wanwan out, "Let's go, Wanwan, let's go wash up together!"
On the day of the defense, sitting in the lounge specially prepared by the school, the three of them discussed in low voices from time to time.
The question A they chose was about African dams.
The construction of this dam was controversial in the beginning and it is now in urgent need of maintenance. The Authority has provided three options to solve this problem:
One, repair existing dams.
Second, rebuild existing dams,
Third, the dams were removed and replaced with a series of ten to twenty small-scale dams along the river.
There are two main requirements on this issue, one is an overview of the potential costs and benefits of each option, and the other is to remove the dam and replace it with a series of smaller dams along the coast that provide a reasonable balance between safety and cost.
Xiao Chong has told Lin Wanwan many times about the problem-solving ideas. Lin Wanwan now has a vague idea and is no longer confused.
For requirement one, after listing the cost and benefit factors, they divided the potential costs into two parts: direct costs and indirect costs.
Then the fuzzy comprehensive evaluation method is used to calculate the relative benefit levels of the three options, and finally the return on investment is calculated.
Finally, it was concluded that option one is more cost-effective in the short term. But in the long run, option three will be better.
For the second requirement, it is necessary to analyze the water transport law and establish the water balance equation of the reservoir and river channel.
On this basis, a multi-functional multi-dam system was proposed. An optimization model was used to select the location for building a new dam, and error analysis was performed on the model.
That's pretty much it.
The keynote speaker for the thesis defense was Xiao Chong.
Zhang Wu is not good at words. He is the kind of person who is very strong but cannot teach others.
Xiao Chong had no requirements for Lin Wanwan, but he definitely had to use it for his younger brother Zhang Wu.
The PPT was basically done by Zhang Wu, and Xiao Chong just checked for omissions and filled in the gaps.
The defense is divided into two parts, one is the thesis explanation, and the other is the judges’ questions.
The purpose of the defense is to verify the authenticity of the paper and see if the contestants are cheating and ghostwriting. It is also an important way for expert judges to understand the contestants’ abilities and levels.
Xiao Chong was already very confident. In his previous life, he was able to handle the performance in front of the emperor with ease, and now it was even more difficult for him to face a few judges.
When he finally finished speaking, he even received praise from two old judges.
After the defense, the three of them went to a music and Internet cafe outside the school to play games and relax.
The specialty of this Internet cafe is that there is a small bar area every night, and there is a resident singer on the stage, the Dream Chaser from Beidiao, who pursues dreams during the day and sings at night.
Xiao Chong likes to come here to drink wine and listen to modern singers singing. It is not much different from listening to female musicians playing and singing in the house before.
Of course, occasionally he would play two games for fun, especially war games, which he liked best.
He even started a guild of 300 people in the game. If he manages it carefully, it will not be a problem to make tens of thousands a month.
However, Xiao Chong was obviously unwilling to spend too much energy in the virtual world. After playing enough, he transferred his account to a younger brother he met in the game at a high price.

The results came out a few days after the defense, and Xiao Chong's team indeed won the first prize in the country.
In addition, there is good news. Their group was also invited to participate in the national organizing committee expert interview.
This means that they may touch the Higher Education Society Cup - this cup is equivalent to the championship among 100,000 players across the country.
This honor is still very valuable.
This year, the expert interview took place in Shuimu next door, and the keynote speaker of the Xiao Chong group was still Xiao Chong.
However, Zhang Wu and Lin Wanwan were also very excited a few days after receiving the news.
After all, he was shortlisted for the finals in his first competition. Who can be calm about this!
Lin Wanwan has been quite low-key recently, not showing off her voice in the dormitory, and for the time being, walking in brocade clothes at night.
Once the dust has settled, the interview has passed, the award has been received, and the publicity period has ended, it’s not too late to wait.
Four days later, Lin Wanwan sat on the back seat of Xiao Chong's bicycle and rode next door. Zhang Wu followed behind on a mountain bike.
Today Lin Wanwan is wearing a college-style gray-green suit and skirt.
The suit above is a loose fit, longer than the hips, with a silk shirt underneath. The skirt is longer than the mini style, and comes with safety pants. It makes her long and white legs look dazzling. The overall outfit is both formal and playful.
This is the model that Xiao Chong bought for her at Sv's press conference in the first half of the year. She likes it very much. After wearing it, she felt like a beautiful girl from a comic and was in a happy mood.
When the three of them locked their cars and walked into the venue arranged by Shuimu University, it was already crowded. In addition to the shortlisted teams, there were also reporters.
Lin Wanwan saw a familiar reporter among the interviewers of China Television. He was a tall and powerful man from the Northeast.
The other party also noticed her, and walked over to Lin Wanwan with a microphone and camera in hand.
"Hello, classmate, are you also a contestant this time? What is your name?"
Lin Wanwan's behavior was quite generous. After all, she had participated in many ceremonial activities and had seen all kinds of big scenes.
"My name is Lin Wanwan, from the participating team of Peking University."
Then the tall reporter asked a few more questions, and Lin Wanwan answered them one by one.
Finally, the other party showed Lin Wanwan a bright and sunny smile, with a row of big white teeth that blinded people: "Thank you for your cooperation."
After the reporter left, Xiao Chong gestured to the person he was talking to, walked up to Lin Wanwan, and asked her, "Do you know her?"
Lin Wanwan nodded and shook her head: "It looks familiar. I met him a few times during my internship in Taili, but I don't know him."
"Oh, I came up to interview my wife. She has good taste."
Lin Wanwan glared at Xiao Chong: "I hate it~ don't talk nonsense. What about you? Didn't two female reporters just come to interview you?"
The two of them were talking when a handsome young man who had been looking at them since just now came over.
He directly ignored Lin Wanwan and Zhang Wu, and stretched out his hand towards Xiao Chong: "Are you Xiao Chong? I am Zhuge Yun, from Shuimu."
Xiao Chong smiled lightly and held his extended hand: "Nice to meet you."
"I've heard about you. IMO, you won a gold medal with perfect scores. You're very good."
"Thank you, thank you."
After Zhuge Yun let go of his hand, he followed up with another sentence: "But although you are very powerful, mathematical modeling is not just mathematics."
After speaking, his eyes swept over Zhang Wu and landed on Lin Wanwan. He felt that the other person was exuding the aura of a weakling, and he couldn't help but feel more confident: "My surname is Zhuge, so I will not disgrace this surname. I believe that today's championship belongs to me.
"
After saying that, he left again.
Lin Wanwan: "Meow, meow, meow?"
Is there something wrong with this guy? He came over and looked at her with contempt, then pretended to be critical, turned around and left?
The surname Zhuge is amazing! It wasn’t the Prime Minister who brought this surname to its peak, and it wasn’t you! Who doesn’t have two royal family members in their ancestors?
This venue was indeed full of academic aura, and Lin Wanwan was like a little sheep that strayed into a pack of wolves. She was particularly out of place, and at the same time, she attracted special attention.
Lin Wanwan suddenly regretted dressing so beautifully. She should have simply worn a set of sportswear.
Now she looks at everyone and feels that the other person has guessed that she came in through the water, Alexander.
Xiao Chong seemed to feel her nervousness hidden under the ice and snow jade face. While looking at the information, he reached out and held her catkins.
His palms are warm and dry, which makes people feel particularly at ease and can give them unlimited courage.
