After returning to Zhou's house, Zhou Ying looked at Ai Qian with a tangled expression.

Although she really wants Ai Jin to become the spokesperson of their products, but what Zhou Hao said also has a certain amount of truth, after all, Ai Jin seems to be quite busy, and after seeing her sign the contract yesterday, she began to read all kinds of information.

also asked Zhou Hao for a stack of A4 papers.

That's right, a pile of A4 paper, a very thick pile.

Then they saw Ai Qi writing a bunch of mathematical formulas and calculations on them that she couldn't understand.

And after Ai Wan, who finished filming at this moment, came back, she continued to devote herself to the same work as yesterday.

Zhou Ju saw that Ai Qian used a lot of A4 paper for the same question, and the solution process written on it was particularly neat, "What are you?" ”

Ai Wan didn't even raise his head, and the pen in his hand didn't stop, and continued to "brush and brush" to write.

The mouth still answered Zhou Yu's question: "It's to write math problems." ”

Zhou Ying was shocked, she had already obtained this title, and she was working so hard, in comparison, she suddenly felt that she was so decadent.

"What's that book next to that?" Zhou Ying looked at the book next to him and asked.

Zhou Ying not only asked, but also took one of the books and flipped through it, all of which were exercises, densely packed, and there was no blank space for answering.

There are 3 questions on a page and 5 questions on a page.

Ai Qian was finally reluctant to take his eyes off the A4 paper, just glanced at the paper in Zhou Ju's hand, and then continued to write.

"It was my mentor at the time, and he said he wanted to co-publish a book with me."

Many of the books published by mathematics majors are exercise books.

"Publish a book?"

"Yes, he has already come up with the questions, and I am responsible for checking whether the questions are reasonable and then writing out the solution process." Speaking of this, Ai Qian began to be a little indignant again, "Obviously, it should be him who tests whether the question is reasonable, and I am not the one who made the question, how do I know what he thought when he came up with the question." ”

He didn't know which formula Professor Zhang was thinking of when he came up with the question, and what theorem came to mind, and she was now like doing her homework.

Last time, she couldn't solve a problem, and she used many methods, all of which were contradictory, so she called Professor Zhang and asked him.

"Professor, question 3 on page 4, is there a problem with the question?"

Professor Zhang over there found the book from his desk, then flipped through it, and after turning to the question, he took a look at it and remembered what he thought at the time, "No, you want to ······ like this"

Then Professor Zhang told Ai Jin his idea, and Ai Jin finally succeeded in solving the problem according to his idea.

By the way, I also wrote another way to solve the problem.

When she asked, "Professor, can you tell me your idea for the next question?" This will save time. ”

The big devil who was known as the mathematics major of the last Imperial Capital University said to the big devil of this year: "No, do it yourself, and ask me when you find a problem." ”

Ai Jin gritted her teeth a little, she has already graduated with a doctorate, and she does not plan to continue her studies, she is not like Professor Zhang, who has retired and can do research with unscrupulous time, she still has to attend classes.

However, no matter what Ai Qian said, Professor Zhang was unwilling to tell Ai Qian his idea of solving the problem, and the reason was particularly reasonable: "I am exercising your problem-solving ability." ”

Ai Xuan, hehe, don't think she didn't see it, he was just lazy, too lazy to move by himself, and by the way, he was torturing her.

The memory was retracted, and Ai Qian looked at the A4 paper in his hand and sighed.

Despair······

It's a holiday, why does she still have to work?

"Well, my sister wants to ask you for a favor." Zhou Yu thought about it, but decided to speak.

"What's the busy?" Ai Wan didn't raise her head, but continued to do her questions.

"That's it, that, my sister's company needs an endorsement ······"

Zhou Xuan's words were half left, and Ai Qian understood what she meant.

"What's that?"

When Zhou Ying heard this, he felt hopeful, "It's clothing, the new clothing of our company, the theme is medieval European aristocracy, my sister thinks it is especially suitable for you." "Since yesterday's dinner, Zhou Ying has thought so.

That behavior, that demeanor, and that temperament are very consistent.

Coupled with going to shoot today, this idea is even stronger.

Ai Jin is really the most in line with this theme since she has met so many people.

"Medieval European aristocracy?" Sounds pretty good.

As soon as Zhou Yu saw Ai Xuan's expression, he felt more hopeful, "Yes, my sister can ask someone to send the clothes over tomorrow." ”

"That ······"

Without waiting for Ai Qian to finish speaking, Zhou Ying hurriedly interrupted and said, "You don't have to give me an answer so quickly, you can wait until tomorrow after you see the skirt and then give me an answer." ”

Ai Wan nodded, that's fine.

Zhou Yu saw Ai Wan nodding and felt that he was getting closer and closer to success, "Then my sister won't bother you, you continue." ”

After leaving Ai Chen's room, Zhou Ying secretly decided that he must pick it carefully and pick the most satisfactory ones to send later.

And what my grandfather said yesterday, it seems that there is going to be a negotiation again······

Zhou Ying looked at the name on the address book on his mobile phone and sighed, he didn't know when it started, and the relationship between the two of them became like this.
