Compared to the excitement of the graduate student brother next to him, Xu Chuan was much calmer and took the invitation letter from Zhou Hai and looked at it.
Well, the format is still the same as before, just as simple.
"Then what do I need to prepare?" After looking at the invitation, Xu Chuan asked Professor Zhou Hai.
After all, it was the 'first time' I received such an invitation, so I still had to ask about the specific operations.
Zhou Hai smiled and said: "Don't be too nervous. Just revise your proof paper, condense the essence, and make it concise and concise. The key point lies in the following questions. You have to put more thought into this."
, the Institute of Science and Technology will compile a list of questions that may arise for you. You can take them back later and look at them more."
"Oh, by the way, the school will be responsible for reimbursing your air tickets, food and accommodation, etc. when you go out this time. Remember to keep the invoice and ask the school for reimbursement. There will be nothing else."
Xu Chuan nodded and expressed understanding.
On the side, Cai Peng came over and asked: "Boss, can you bring someone with this invitation? Can you take me with you to have a long experience? I will pay for it at my own expense!"
Xu Chuan smiled and said, "You have to ask the teacher about this, I don't know."
Zhou Hai glanced at it and said angrily: "Okay, don't be embarrassed, hurry up and write your graduation thesis. It has been delayed for half a year and you don't even have a title."
Xu Chuan thought for a while and typed in the name field. There were not many people in his address book anyway, so there would be no confusion.
Xu Chuan said, slamming the dormitory door shut with his backhand.
After returning to the dormitory, he threw his schoolbag on the bed. Xu Chuan picked up his math book from the table. Just as he was about to read it, his eyes fell on the hot water bottle in the corner.
"Huh? Is there anything else?" Seeing Xu Chuan returning, Zhou Hai asked curiously.
"Thank you, teacher."
"Hello, may I ask what time you are in the dormitory? I can just go and get it."
"Well, teacher, can you give me the contact information of the senior sister you asked to deliver medicine to me last time? I haven't given her the money for the cold medicine yet. It's been delayed for several days."
But when he was typing notes, Xu Chuan was stunned. His finger hovered on the screen, not knowing what to note.
Putting down the phone, Xu Chuan picked up the math textbook and before even looking at it twice, the message came back with a ding-dong sound.
Zhou Hai smiled at Xu Chuan, his smile was a little narrow, which made Xu Chuan feel a little strange. Needless to say, of course he had to thank him properly.
"I'm ashamed to say that, senior sister, I don't know your name yet?" The two of them walked out of the school one after another. Xu Chuan suddenly stopped and turned around and asked.
After replying, Xu Chuan felt a little embarrassed. After all, someone else had helped him. Forget it, he would ask his senior sister to go to Xiaoxianzhuang for a meal later to express his gratitude.
Bang bang, a message was sent.
Xu Chuan responded, turned around and walked into the dormitory, picked up the water bottle from the corner, and took his mobile phone and keys with him.
After a brief exchange, Xu Chuan scratched his head and looked at the time on his phone. It was around five o'clock in the afternoon, which was time for dinner.
As soon as he reached the office door and stepped out with one foot, he suddenly remembered another thing, turned around and went back.
The senior who was following him didn't expect him to stop and almost bumped into him.
"Liu, Liu Jiaxin." The senior said in a low voice.
Outside the door, the senior stretched out her hand, ready to take the thermos bottle, but unexpectedly Xu Chuan had no intention of giving it to her, and said while holding the thermos bottle:
"Hey, if you hadn't brought me medicine and hot water, I don't know when I would be cured of my cold. I know there is a restaurant with pretty good food. I'd like to give it a try, senior sister."
As if she didn't expect Xu Chuan to behave like this, the senior was stunned for a moment and then rejected in a panicked voice: "No, no need."
Xu Chuan quickly put down his book and went to open the door. Standing there was the senior sister who had delivered medicine to him two days ago. She still looked familiar, with long black hair hanging down, and carrying a backpack. She had her head lowered and it was hard to see clearly.
face.
"Okay, then I'll wait for you in the dormitory."
Hearing this, Zhou Hai took out his mobile phone and looked through his address book. After finding the number, he sent it to Xu Chuan.
"Well, thank you very much."
Make a note of your name and click on the message: "Hello, senior sister, I caught a cold two days ago and you sent me the medicine, Xu Chuan. When is it convenient for you, I will return the hot water bottle to you."
"Wait a mininute."
"I'm really sorry to trouble you to make a trip again."
Because he didn't seem to ask the senior sister's name from the beginning to the end.
"Forget it, let's take note of the senior sister first."
About six or seven minutes later, there was a knock on the door.
Looking at the locked dormitory door, the senior was stunned again, glanced at Xu Chuan, and then at the thermos bottle in Xu Chuan's hand. She seemed to be hesitating about something, but nodded after a while.
"No, it's okay, just give me the hot water bottle." The senior replied softly, raising her head slightly.
"No, I can go over and get the hot water bottle. If you are in the dormitory now, just wait for me for a few minutes."
Patting his head in frustration, he took out his phone and saved the number sent by Professor Zhou Hai to his address book.
After solving the problem at hand and receiving an invitation letter from the Princeton Mathematical Society, Xu Chuan stood up with satisfaction and said goodbye to Professor Zhou Hai before getting up to return to his dormitory.
After the message was sent, the other party did not reply again. Xu Chuan also put down his mobile phone and picked up his math book again.
"Oh, that's it. Just wait a minute. I'll look for it and I've sent you the number."
"No, I sent it to you, but I haven't thanked you yet. I also didn't give you the money to buy cold medicine."
"Senior sister, it's dinner time now. Let's go have a meal together. I had a cold before and I haven't thanked you properly."
"Liu Jiaxin." Xu Chuan nodded, took out his phone after writing down his name, and modified the notes in the address book.
"By the way, your prestige is your mobile phone number? I added you, but I haven't given you the money for cold medicine yet."
After changing the remark, Xu Chuan copied the number to Weixin, found a Weixin signal, and clicked to add it.
"I've added you. Once approved, senior, I will transfer the money for the cold medicine to you." Xu Chuan shook his phone and said.
