After class in the evening, the rainstorm outside had already decreased a lot, and after Duan Yun sent Cheng Qingyan downstairs to her house, he quickly returned home.

My sister Duan Fang was still immersed in studying, and it was already half past ten in the evening.

"Are you done?" Duan Yun asked.

"Brother, this roll is a bit difficult to ......," Duan Fang said lightly biting his lower lip.

"I'll see. Duan Yun reached out and took the scroll from his sister's hand.

Just looking at it for a while, Duan Yun frowned.

Duan Fang did no problem with the simple fill-in-the-blank questions in the front, but in the application questions in the back, Duan Fang could only solve several questions in one step, and the difficulty of the questions obviously exceeded Duan Fang's level.

However, Duan Yun's questions this time were indeed not difficult, and it could even be said that they exceeded the difficulty of the questions in his previous life's high school exam, in order to test how much potential Duan Fang had.

Judging from the test paper she made, Duan Fang's basic knowledge is still quite solid, but the thinking of solving the problem is a little solidified, and there are more routines in the test questions, so she is a little struggling.

In fact, Duan Yun also understood that his questions should be higher than the high school exam papers in this year, and the reason why he still had such difficult questions was to strengthen Duan Fang's problem-solving ability.

This is just like people who practice martial arts like to add a sandbag to their legs when running, and after a long period of exercise, once they take off the sandbag, they immediately feel like they are flying.

If you do more difficult questions, it will be much easier to do simple test questions, although this may not be the most effective way to tutor for the college entrance examination, when the effect is definitely there.

"You should think differently about this question......" After thinking for a while, Duan Yun picked up the scroll and began to explain it carefully to Duan Fang.

Duan Fang didn't believe that her brother really had such a strong high school foundation, but in the past two days, as her brother lectured her every day, Duan Fang also felt a lot of shock in her heart, except for some rote things in Chinese, Duan Yun's level of mathematics and English is scary, especially the English level, in addition to being able to translate English articles, the spoken English is even more fluent, and he also claims to be a standard 'Oxford accent'!

Duan Fang couldn't figure out where his brother learned such a solid high school course, and in the end, he could only blame it on the six years when he went to the countryside in Shaanxi......

But in any case, it is a great thing for Duan Fang that his brother studies so well, he can ask questions at home at any time, and his brother is obviously more conscientious than the teachers at school, the test paper is basically one a day, and the level and difficulty of the proposition are obviously higher than the school test papers.

Working during the day, attending classes at night, and tutoring his sister when he returns home at night, Duan Yun is a little tired, but his life is quite fulfilling.

Outside the window, the rainstorm had stopped, and the dark clouds in the sky began to dissipate, revealing a little starlight......

......

Early the next morning, Duan Yun went to work as usual.

Cheng Qingyan showed up in Corey, and after giving others some work, she took the drawings that Duan Yun helped him modify yesterday and went to the workshop to find someone to process the machine workpiece.

Duan Yun continued to write test papers for his sister.

For Duan Yun, tutoring his sister for the college entrance examination is also a very good investment.

As far as the current situation is concerned, the scale of his workshop has reached a bottleneck, and there is no need to spend a lot of time and energy on expansion for the time being.

And in the current relatively idle time, it is necessary for Duan Yun to support his sister.

If Duan Fang can really be admitted to university in the future, it will undoubtedly become a powerful help for himself, on the one hand, Duan Yun needs to have a large number of highly educated talents around him, on the other hand, he can go to full-time college this year, and then basically become a unique figure in various industrial and mining enterprises and government departments, so Duan Fang will also know a lot of valuable contacts in the university, and in the future, Duan Yun can establish a stronger network of contacts through his sister Duan Fang.

However, this matter is not easy, Duan Yun had a high education in his previous life, but it does not mean that he is a good teacher who can turn stones into gold, so Duan Yun is also gradually exploring the best way to tutor his sister.

After getting off work in the afternoon, Duan Yungang wanted to leave the department, but saw Cheng Qingyan standing at the door of the department at a glance.

Duan Yun. Cheng Qingyan greeted Duan Yun, and then saw that there was no one around, and said, "I haven't thanked you for helping me revise the drawings this time, didn't you say that you want to take pictures today.........

"Hmm. Duan Yun thought for a moment when he heard this, and then said with a smile: "That's it, wait a while, you go home first, change into your most beautiful clothes, and then I'll pick you up and take pictures at my new home." ”

Duan Yun originally wanted Cheng Qingyan to take a photo in his workshop, but he felt that the rental house was too old and the background effect was poor, so he decided to shoot it in his new home, and at noon, Duan Yun had already moved the speaker samples from his workshop to his new home.

"Okay. Cheng Qingyan nodded in response.

"Then let's get off work together. ”

"Hmm. ”

The two then left the building.

After Cheng Qingyan returned home, she walked straight to the wardrobe in her room, opened the cabinet door and picked out clothes.

Compared with girls of the same age, Cheng Qingyan's living conditions are much better, so she has a lot of various clothes in her private wardrobe.

In fact, Cheng Qingyan does not belong to the kind of girl who is keen to dress herself up with fancy looks, but she pays attention to her personal image, whether she goes to work or participates in activities, she maintains a simple and capable dress temperament, plus natural beauty, so it is easy to make a deep first impression.

Soon, Cheng Qingyan chose a long dress with a plaid painting and changed it on her body.

In fact, since these years are all black and white photos, the clothes do not need to be colorful, and the effect of simple and simple clothes will be better.

In addition to the clothes, Cheng Qingyan untied her ponytail, reorganized it, brought a phoenix hairpin, and put a silver bracelet on her wrist, and the whole person suddenly had a bit more exquisite and classical temperament.

After changing into a pair of white sandals at the door, Cheng Qingyan pushed the door and left the house.

At this time, Cheng Qingyan's parents hadn't gotten off work yet, so she didn't say hello, so she was ready to take pictures with Duan Yun.

Soon, there was a sound of an engine in the distance, and Duan Yun rode his nephew and quickly appeared in Cheng Qingyan's field of vision.

After seeing Cheng Qingyan's dress, Duan Yun's eyes couldn't help but light up, and then he parked the car in front of her and said, "Get in the car." ”

"Hmm. Cheng Qingyan nodded and sat on the sidecar.

"Tubu!"

With a puff of white smoke rising from the rear of the car, the car quickly drove towards Duan Yun's new home......
