For a whole afternoon, Duan Yun was teaching Cao Dong the skills of assembling the Yagi antenna.

Cao Dong is indeed very hard-working, and he is also quite diligent, which makes Duan Yun very satisfied.

In Duan Yun's opinion, a useful assistant must either be smart enough and able to speak, or he is diligent and has eyesight in his work, otherwise, he can't stay by his side for a long time.

Cao Dong is obviously not stupid, Duan Yun has only demonstrated once, he has basically mastered the key points of making an antenna bracket, and when he assembles the third one, there is no difference from the antenna made by Duan Yun himself.

In fact, the difficulty of this antenna bracket is not high, the focus is on some subtle size spacing values, out of a precaution, although Duan Yun told the various size data of this antenna shelf, but did not tell him the mystery of it.

In one afternoon, Cao Dong made six antenna racks, and Duan Yun was very satisfied with the quality of workmanship.

In the evening, after Duan Yun received a notice from his sister, he went to Li Yun's house again.

After Li Yun's mother got the benefit fee given to her by Duan Yun last time, she worked harder to promote his antenna, and her two female colleagues who had also installed the new antenna were full of praise and boasting, so when it was time to go to work in the afternoon, two more families found Li Yun's mother and wanted to install the antenna.

Now Duan Yun is also familiar with Li Yun's family, and after chatting a few words in the house, after getting one hundred and twenty yuan, Duan Yun led Cao Dong to start the door-to-door installation.

This was a good opportunity to teach Cao Dong to install antennas independently.

In fact, this kind of work is also not difficult, you only need to choose a place with the best signal outside the user's window, and then simply use an electric drill to punch holes in the wall and install the angle iron bracket.

When it came to the first house to install, Duan Yun demonstrated one side, and when it came to the second house, Cao Dong volunteered to complete the installation independently.

However, when the antenna was installed for the second family, there was a little hiccup in the middle.

The family's window was located right around the corner of the house, and the signal was always bad after the antenna peeked out of the window.

In this case, the usual practice is to only set up the antenna on the roof, but because the iron door at the entrance to the roof is locked, the person who took the key did not come back from the second shift, and in desperation, Duan Yun planned to install it again tomorrow.

And at this time, Cao Dong suddenly tied the antenna behind him, and then went down the drainage groove next to the window to the roof!

This scene really made Duan Yun's heart tremble, but fortunately, Cao Dong finally installed the antenna on the roof of the building without danger, and after the debugging was successful, he stuck the drainage groove with his fist and climbed down from the roof like a monkey!

They were busy until more than eight o'clock in the evening, and then the two finished their work and left the user's home.

Duan Yun still feels quite satisfied today, at the end of the day, Cao Dong has basically learned this set of antenna installation technology, and from now on, he can come to the door alone to install it when Duan Yun goes to work or makes up the handover.

"Brother, it's really fun today!" Cao Dong said to Duan Yun with an excited face.

"What are you excited about?

"Anyway, I'm just happy in my heart!" Cao Dong said with his head tilted.

"Are you happy?" Duan Yun snorted, and then said: "I was almost scared to death by you just now! You didn't say hello, you just climbed the roof of the mountain alone, in case something happened and fell down, it would be too late for you to regret it in this life!"

Duan Yun was really angered by Cao Dong's behavior of climbing the roof just now, but because the user was present at the time, he still boasted that the two of them were working well, so Duan Yun did not reprimand Cao Dong at that time.

But Duan Yun knew that if Cao Dong did it so recklessly in the future, once something happened, he would probably regret it for life!

"Brother, it's really fine. Hearing Duan Yun's reprimand, Cao Dong's face flashed with disapproval, only to hear him continue: "Brother, when I was a child, I climbed over that house and dug out the bird's nest, and when I went to the factory to steal iron last year, the three-meter-high fence went up with a run, and it was just a piece of cake......

"Shut up for me!" Duan Yunyan's face became a little more angry when he heard this, and he said loudly with a straight face: "I'll tell you the ugly words now, it's okay to climb the house, but there must be safety measures, I'll buy you a safety rope when you go back, and you must tie it to me when you go to the house, once it happens again like today's bare-handed climbing, you get out of the house as soon as possible, I don't want you here!"

Duan Yun said this a little ruthlessly, but he also knew that although this Cao Dong was very clever and diligent, he was still too young, and he had a 'tiger' energy in his bones.

If Duan Yun let him go through today's events lightly, it is very likely that something will really happen in the future, after all, that kind of old house is not strong, once Cao Dong catches it or the bricks and stones on the edge of the roof are broken, the consequences will be unimaginable.

In Duan Yun's view, both work and business must be stable, and only in this way will the boat not capsize in the gutter.

"Brother, don't be angry, I was wrong. Seeing the anger on Duan Yun's face, Cao Dong was suddenly a little flustered, and hurriedly said, "This won't happen in the future, I promise!"

"Hmm. Seeing that Cao Dong admitted his mistake, Duan Yun's face softened a little, and after a while, he turned to Cao Dong and asked, "Are you hungry?" ”

"It's okay......" Cao Dong licked his lips.

"This point restaurant is also off work, and I still have some leftovers at home, if you don't dislike it, come to my house to eat." Duan Yun said to Cao Dong with a smile.

"Brother, I think we can make do with this meal in the evening, I still have a stomach that I eat at noon, and my stomach is churning for a long time when I was working just now......," Cao Dong pouted and said.

"Hahaha, yes! Your virtue of eating at noon is simply a starving ghost! Frightened the waiters. Duan Yun laughed, and then said, "Either way, I'll buy you a few more cakes, right?"

"I'd better buy it, why don't I invite my brother to eat. Cao Dong said again and again when he heard this.

"Aren't you afraid that the old man recognized you yesterday?" Duan Yun said with his hand, pointing to a few vendors selling cakes in the distance.

"I also admit to being beaten, I was wrong yesterday, I was really hungry and fainted...... Cao Dong said, took out the five yuan that Duan Yun had prepaid him at noon from his pocket, and said: "Brother, when I meet you, I can be regarded as meeting a nobleman, I don't thank you for my kindness, but I have to invite dinner today, at least you can make me feel a little more comfortable, right?"

"Hehe, then you please. Duan Yun said with a smile.

Duan Yun could see that Cao Dong's words were quite sincere, and the poverty of several years had not made him extremely vicious and ungrateful for it, at least he was a good person, and Duan Yun's last doubts about him before suddenly disappeared......
