Yu Jin's house.

Li Qian, who came back, after chasing the latest episode "Ode to Joy" accompanied by her husband, looked at her son who had not slept at almost twelve o'clock, got up and knocked on the door.

She whispered at the door and reminded: "Son, it's not too early, rest early, and study again tomorrow." ”

"Okay, Mom, there's one more point, I'll go to sleep right away."

Li Qian said with concern: "Pay attention to your body, you have good grades now, you don't have to work so hard." ”

People want their children to study more and rest less.

Every day, their family persuades their children to study less and rest more.

"I see."

Half an hour later, Yu Jin was finally almost tidy up.

He got up and shook his neck, moved his body, and then picked up his phone and sent a message to Jiang Muqing.

[Nine o'clock in the morning, don't be late.] 】

……

The next morning, when Zhang Hui, who got up, was helping her daughter pull out the charging cable, she undoubtedly saw an unread message displayed on the mobile phone screen.

[Pig's head: Nine o'clock in the morning, don't be late. 】

"Pig's head" is Jiang Muqing's WeChat remark name to Yu Jin.

After Zhang Hui saw it, she guessed that it was probably the morning tutoring time agreed by the two.

So I kept it in my heart.

After she finished breakfast, seeing that the time was almost up, she woke up Jiang Muqing and said, "Daughter, get up for breakfast." ”

"Mom, let me sleep a little longer." Jiang Muqing covered her head with the quilt and didn't want to get up at all.

Zhang Hui reminded: "Didn't you say that you were going to tutor today?" ”

"Tutoring?" When Jiang Muqing heard this, she immediately sat up in shock.

That's right, how can I forget about it after I get some sleep!

"Mom, what time is it?"

She asked, while quickly turning over and picking up the mobile phone on the bedside and looking at it.

"Around 8 o'clock." Zhang Hui replied.

At this time, Jiang Muqing also saw the message from Yu Jin on her mobile phone.

She breathed a sigh of relief and said, "It's okay, it's okay, the time he made an appointment is nine o'clock, and he is in a hurry." ”

"Really?"

Zhang Hui smiled: "At this time, it is just right for you to get dressed, wash up, and go after breakfast." ”

"Mom, thank you, if it weren't for you, I would be late."

"Well, get up."

After a while, Jiang Muqing came to the dining room, ate noodles, and asked with some curiosity, "Mom, where is Dad?" Why didn't you see him? ”

"I went out early in the morning, saying that the company was in a bit of a hurry to deal with."

"Oh."

When eating, Jiang Muqing didn't forget to turn out the periodic table, seize the time, and remember while eating.

After all, if we meet later, we will be slapped by someone.

Seeing this, Zhang Hui smiled and said, "Daughter, you are working too hard." ”

"There's no way, they're my tutors now, so if you don't listen, you can't do it."

After eating, Jiang Muqing put on her schoolbag and went out.

Zhang Hui encouraged in the back: "Daughter, come on!" ”

Jiang Muqing was not idle along the way, and kept chanting in her mouth: "Hydrogen, helium, lithium, beryllium, boron......"

On the other hand, Yu Jin also told his family that he was going to the bookstore to read books, and he might not come back until evening, so he didn't need to wait for him to eat together at noon.

Yu Donglai and Li Qian responded, but they were not suspicious.

Because this is a very normal weekend behavior for Yu Jin.

Ten minutes later, Jiang Muqing came to yesterday's KFC store.

Yu Jin was waiting for her there early.

Because it was too early, there was no one in the store, just him, and two waiters, very quiet.

Yu Jin had already ordered coffee this time, and when the waiter saw Jiang Muqing coming, he brought two cups of coffee.

Jiang Muqing asked, "How long have you been here?" ”

"It's just there."

Yu Jin didn't talk nonsense, directly handed her a piece of paper, and said, "Let's start remediating chemistry now, you first write down the periodic table and their properties for me silently." ”

"Didn't you say back?"

Yu Jin asked rhetorically, "Is there a difference?" Or do you simply not remember? ”

"......" Jiang Muqing.

Of course, there is a difference, dictation is much more difficult than memorization!

Jiang Muqing complained in her heart, then took out a pen and began to write silently on the paper.

Yu Jin didn't look at it, but took out the high school chemistry textbook and training workbook in her bag, and prepared the next tutoring materials.

"Let it go, I'll give up."

Jiang Muqing put the pen down: "I haven't remembered it yet." ”

Yu Jin took it and looked at it, the elements on the periodic table were all written correctly, and most of the characteristics were also written, but they were not complete.

But this has already reached Yu Jin's expectations.

In fact, in such a short period of time, he didn't expect the other party to remember and write it all out.

But in order to make the other party work as hard as possible and not be lazy, he deliberately made it more difficult.

"Forget it this time."

Yu Jin pretended to be generous and said: "Next time I use dim sum, I can't memorize such a simple thing." ”

"......." Jiang Muqing.

"Now, let's start tutoring."

Yu Jin looked at Jiang Muqing, who was sitting opposite her, and said, "Do you want to sit next to me, otherwise what do you think?" ”

"Okay." When Jiang Muqing heard this, she happily sat down next to Yu Jin.

Yu Jin moved her ass to the side, keeping a little distance, and then flipped through her chemistry notebook.

"Let's look first at [the classification of matter and its transformation]."

Jiang Muqing looked at the brand-new chemistry notebook, with the new color labels, and some notes on the expansion of knowledge points, and said, "You didn't get all of these yesterday, right?" ”

"Or else?"

Yu Jin replied casually: "These knowledge are some of the knowledge points of chemistry that I have summarized by myself. ”

"......" Jiang Muqing.

Husband, it's much stronger than I imagined.

"Okay, don't interrupt, study hard, our time is precious!"

Yu Jin pointed to the important knowledge points in the book with a pen and continued to explain.

"The first is the classification of the composition and properties of matter ...... 'tree taxonomy'...... Mixtures and purities...... Colloidal ...... Tyndall phenomenon ......"

“…… For example, acids and metals belong to displacement reactions, while acids and alkalis belong to metathesis reactions......"

"Alright, now, you try to write for me the transformation relationship between Ca→CaO→Ca(OH)2→CaSO4."

“.......”

The time of study passed quickly, and soon it was noon.

There were more people in the store, and the surrounding environment began to be noisy, and it was no longer possible to study normally.

"We're all hungry, let's order something first."

Jiang Muqing scanned the code and ordered a family bucket.

After eating, the two began to discuss where to tutor in the afternoon.

"A place that is both quiet and warm......"

Jiang Muqing thought about it, her eyes lit up, and she said, "Yu Jin, why don't you go to your house?" ”
