Chapter 673 You are standing outside

"Qian Zhengzhi, Liu Juanxiu, Zhao Hongbo, this is your second time here, you should understand my rules, take care of this young comrade."

In front of Mr. Song, the three of them nodded repeatedly.

After saying this, Mr. Song waved his hand.

"You go to Yishan for class first."

Qian Zhengzhi smiled and nodded, "Okay, Mr. Song, take care."

After Mr. Song left, Qian Zhengzhi and the other two looked at each other and exchanged glances.

Liu Juanxiu took the initiative to say, "I want to go to the toilet, you guys go first."

Qian Zhengzhi and Zhao Hongbo followed suit, "We'll go too."

Liu Juanxiu looked at Jiang Yu, "Are you going?"

Jiang Yu shook his head, "I'll wait for a few people here."

"Okay, then don't walk around, wait for us to come out."

The three of them walked towards the toilet, but did not go into the public toilet, but turned a corner.

Qian Zhengzhi hesitated and said, "Will it be bad to leave her behind? This is her first time here, she must not know where to go to class."

To be honest, he is ten years older than Jiang Yu, and the few people present are considered Jiang Yu's elders. He felt guilty for using these tricks.

Liu Juanxiu glanced at him, "If she hadn't interfered, it would have been Qiaojie who came here to study with us today. How could she, an unqualified young person, get the chance? The National Cotton Mill is also ridiculous, letting a woman in her early twenties serve as the deputy director of the third factory."

Zhao Hongbo glanced at her lazily, "No matter how wronged she is, she is not as wronged as Qiao."

Qian Zhengzhi shut up and stopped talking about Jiang Yu.

Meanwhile, Jiang Yu waited for a while and found that the three people had not returned yet. She couldn't help but go to the public toilet to take a look.

As a result, the public toilet was empty and there was no one.

Seeing this, she still didn't understand something. She was fooled by those three people.

Now she didn't know where the class was. After walking around the research institute, she finally found someone to ask and found the classroom for the class.

Meanwhile, Tan Yishan had already finished half of the class.

Seeing that Shanshan was late, Jiang Yu's face turned cold and he did not let her in.

"You stand outside."

Jiang Yu understood why he was angry and explained in a gentle voice: "I'm sorry, Teacher Tan, no one told me where the classroom was. I walked around the institute for a long time before I found the classroom."

It was quiet here with few people and few people wandering around on the street. If she couldn't find anyone, she had planned to go home first.

However, Tan Yishan did not listen to her explanation.

"If I tell you to stand at the door, just stand there. Here, there are only teachers and students, but no deputy factory director. There is no point in putting on airs with me."

Jiang Yu shrugged and said, forget it.

She turned around and left without paying attention to how ugly Tan Yishan's face was.

Seeing this, Tan Yishan angrily scolded: "If you leave today, don't come here again in the future. Our institute can't afford students like you!"

Jiang Yu left without looking back.

Before leaving the institute, she met Mr. Song halfway.

The person walking side by side with him was also an old acquaintance of Jiang Yu, Mr. Jiang.

"Isn't this Jiang Yu, why are you here?"

Jiang Yu stopped and greeted him with a smile: "Mr. Jiang, Mr. Song."

Mr. Song glanced at her and asked: "Why didn't you go to class?"

Jiang Yu simply explained: "I couldn't find the classroom, I was late, and Teacher Tan didn't let me in."

Although she didn't mention Qian Zhengzhi and the others, Mr. Song already understood the reason.

Otherwise, Jiang Yu was obviously with the other three people, how could she not find the classroom.

"Teacher Tan doesn't allow you to attend the class, so you don't go? As the deputy director of the National Cotton Mill, you have to learn to consider the overall situation and be less impulsive."

Jiang Yu said, "Then can I leave?"

Mr. Song: "..."

She didn't hear a word he said.

He laughed angrily, "Answer me a question and I will let you go."

"Uh-huh, go ahead and ask."

Old Song said, "What are the raw materials of polyester fiber?"

Jiang Yu was speechless for a moment, "Aren't you kidding me? If I remember correctly, the polyester fiber we are currently using is all imported, and there is no chemical fiber factory in the country. If there was already synthetic fiber technology, you wouldn't have to work so hard."

Old Song did not comment on her words, but instead advised, "It is precisely because the country does not have this technology that you younger generations need to work hard! With this attitude, how can you lead the country to progress and development?"

Old Jiang felt that his words were too serious and wanted to smooth things over.

But she heard Jiang Yu ask: "If I answer this question, will you let me go?"

Old Song laughed, "Yes, I'll let you go."

Jiang Yu recalled Qin Yun'an's reply to her, in which the raw materials of polyester fiber were mentioned.

But they were all professional terms, and she didn't remember them. She only knew that they were:

"petroleum by-products."

Old Song and Old Jiang looked at each other, and their throats felt like they were blocked by cotton.

In just a few seconds, Old Song's mind turned over and over, and all kinds of data went through his mind.

"Jiang Yu, how did you know?"

He didn't think that Jiang Yu, at such a young age, would be more professional than him.

Jiang Yu was too lazy to explain so much to him, so she said: "Old Song, why don't you wait here, I'll go back to get something?"

Old Song stared at her eagerly, and he was reluctant to let her go.

"I'll go back with you."

He was afraid that Jiang Yu would leave like this.

Jiang Yu had no choice but to let him follow her.

When she got home, she found the letter Qin Yunan had sent her.

"My senior brother is in Hong Kong. His company has a chemical fiber factory, which produces polyester fiber."

Speaking of the lagging behind of domestic chemical fiber technology, Qin Yun'an is actually very willing to help the country develop, but he has not found a suitable opportunity to introduce it yet.

Mr. Song read the letter at a glance, his hands shaking with excitement.

"Jiang Yu, can I transcribe a copy?"

Jiang Yu nodded, "Of course, even if I didn't tell you today, I would still hand in this information."

It's just that the letter just arrived yesterday, and she hasn't had time to sort it out.

Mr. Song buried his head in transcribing, his eyes wanted to stare through the letter paper, and he copied it word by word very carefully.

After copying down the important information, he carefully put it into his pocket as if it were a treasure.

Jiang Yu looked at it and didn't know whether to laugh or cry, "Why don't you just take my letter back."

Mr. Song wanted to, but he thought it was impolite.

Compared with this letter, he wanted to contact this comrade Qin Yun'an more.

"How could this comrade be willing to reveal such an important technology to you?"

He was excited, but still had some reason, and began to doubt the authenticity of this information.

Jiang Yu understood his concerns, so he told him about the Qin family's experience.

After listening to the whole story, Old Song only grasped one thing.

"You said he wanted to come back to invest and build a factory?"

Jiang Yu nodded, "Yes, Senior Brother has been looking for an opportunity to come back, but he can't find one. Not only to invest in building a factory, he is willing to donate the chemical fiber technology mastered by his company to the country unconditionally."

Old Song sighed: "Comrade Qin is righteous, I can try to apply, in the name of the research institute, to invite Comrade Qin to come to North City for exchanges and learning."

However, there are many procedures involved, and it may not be approved.

He was about to go out, but suddenly stopped.

"You, come back with me."

Jiang Yu: "...You said it yourself, if I answer the questions, you will let me go."

Song Lao said righteously: "You are going home now, and I didn't say that you don't have to go back to the institute after you leave."

Jiang Yu: "?"
