Xu Yun first silently recited Meng Qingwen's name in his heart, completed the binding and started the task of being a teacher, and then took out a math test paper from the desktop, circled a few questions on it with a pen, and handed it to Meng Qingwen again.

"You try to do these questions first, let me see which of your basic knowledge is weak."

"Just do it."

Meng Qingwen didn't know who was more energetic, so she took the test paper and wrote it without saying a word.

It took about twenty minutes to barely finish the answer.

When the test paper returned to Xu Yun's hand, he checked the process and answers to these questions, and his brows furrowed involuntarily.

Meng Qingwen's knowledge of mathematics was even worse than he thought.

Not only are the answers basically wrong, but there are also big problems in the process and ideas of problem solving.

"Hey."

"What's that look on your face?"

At this time, Meng Qingwen noticed the change in Xu Yun's expression, and couldn't help but ask out loud, and the corners of her mouth turned to the left to make an unhappy look.

And this time, Xu Yun didn't get used to her, and directly retorted angrily.

"You're embarrassed to say it."

"If you can be so wrong, it shows that you didn't listen to the class at all."

"Is it really that bad?" Meng Qingwen's momentum fell instantly.

In the next time, Xu Yun officially entered the role of a teacher, and combined these questions to explain to Meng Qingwen that it involves basic knowledge.

Because his abstract thinking ability has been greatly improved, he can tell the core points more intuitively, so that the audience will be very easy to understand thoroughly.

Therefore, in just over ten minutes, Meng Qingwen changed from a casual attitude to a serious one.

In the end, he was full of admiration for Xu Yun.

She never imagined that one day she would find math as difficult as she imagined.

……

"As long as you grasp the core idea of the simplification of the absolute value, it is to judge the positive and negative of the internal formula of the absolute value.

"Otherwise, you can do it right."

Meng Qingwen listened carefully to Xu Yun's explanation, and her original solemn expression gradually became relieved.

It's as if the math cluttered in my head has been straightened out.

"I see."

This is something that would never happen when listening to a teacher in school.

If she was disgusted with mathematics before, then under the influence of Xu Yun, she became interested at this moment.

Looking at this question with a distracted expression, she muttered to herself, and when her emotions calmed down a little, she looked at Xu Yun with a serious face.

"Teacher Xu."

"Why is it that I can understand what you say, but not in school?"

"Am I too stupid or am the teachers at school low?"

Of course, Xu Yun can't say that this is because his abstract thinking ability has been greatly improved, and the ordinary teachers in the school definitely can't compare, so he responded from the side with a slight groan.

"I think you're pretty smart."

After speaking, I saw that the time had come to six o'clock, and I was ready to end today's two-hour tutoring.

"That's all for today."

"In the evening, you will follow the tutoring plan I wrote for you, and start with the weak areas to master the basic knowledge, which is the key factor in whether you can do the questions quickly and accurately."

"Thank you, Mr. Xu."

Looking at the back of Xu Yun leaving, Meng Qingwen stood up and sent it to the door to express her gratitude very respectfully, and it was like two people two hours ago.

Hearing this, although Xu Yun only waved his hand and did not look back, a relieved smile appeared on his face.

Meanwhile.

Zhang Hongqin, who was watching the monitoring equipment with her mobile phone in the master bedroom, noticed that Xu Yun came out and hurriedly got up and walked towards the living room.

At first, she was really worried about Xu Yun, after all, the other party was too young.

can see that her daughter is willing to calm down to listen to the lecture, and the previous worries disappeared without a trace in an instant, and even expressed her joy that she left Xu Yun to make such a correct choice.

"Teacher Xu, Wenwen didn't trouble you, did she?"

Zhang Hongqin came to the living room and called Xu Yun, asking with a gentle attitude and not forgetting to hand over the money.

Xu Yun would definitely not be polite to what he deserved, and reached out to take the three red tickets and put them in his pocket while expressing relief.

"Don't worry, Sister Qin."

"Wenwen still has a certain talent in mathematics, and I believe that through the summer tutoring, her grades can be greatly improved."

"That's so thankful." Zhang Hongqin was very excited when she heard this.

Xu Yun and Zhang Hongqin made an appointment to come over tomorrow, then turned around and walked into the elevator to go downstairs, and let the panel appear to check the progress information on the task page.

"At this rate, this task should be completed in half a month at most."

Noticing that the progress of the task had successfully increased by two hours, he thought to himself.

Soon walked out of the Dihua Hongfu community, entered the nearby subway station and took the subway back to the rental house, on the way Chen Shihe also sent a message to ask about the tutor, and he also told the other party 1510.

It wasn't until seven o'clock in the evening that he returned to his house after dinner.

Skillfully turn on the computer and sit down, enter the background and see the data of the image restoration tool the same as in the morning.

It can basically be described in four words.

A pool of stagnant water.

It's just that his mood at the moment is different from that of the morning.

He had thought a lot about image restoration tools throughout the day, and thought he still had to take some action.

There is no problem with the software itself in terms of pricing or effect, and it is definitely the best choice for users in need, and the key is to take what method to let these users see the effect. Otherwise, who would be willing to spend money to try it without knowing if the restored photo effect would be worth the price, after all, everyone's money is not blown by the wind.

Of course, he also thought of other options.

For example, set the number of free times.

It's just that this plan didn't come out long before it was scrapped.

The image restoration tool targets a fixed group of users, and how many photos each home needs to restore.

If you really want to have a number of free times, it is estimated that the demand will be met directly.

In this case, it is better to take the route of free operation.

Under the rapid operation of thinking, I saw Xu Yun open the browser and type out a few words with both hands on the keyboard.

Kuaishou short video.

In the afternoon, when he saw Meng Qingwen watching the video, he suddenly popped up in his mind about self-media, a new word that has been popular recently.

Since you don't have the money to promote it for the time being, let's make your own video and publish it.

With the number of tens of millions or even hundreds of millions of users on major video platforms, there is a high probability that the image restoration tool will attract interested users, so it can be regarded as a successful first step.

"Sign up for a platform account first, and then learn video editing, I don't believe that no one will watch it then."

Xu Yun planned what he was going to do next, and when he took action, he registered accounts on Kuaishou Weibo and other stations with Deepin Technology, and found a video editing software on Beep Station to teach video learning. Once he was familiar with the process, he opened the edited software he downloaded and imported the before-and-after comparison images of the photo he had tested.

Paired with a demo of the image restoration tool and background music, a video of less than two minutes was quickly produced.

Watch it from the beginning, make sure there are no problems, and upload it on various video platforms.
