How Should I Choose?

Na Rulong introduced Mingyang on the way to the multi-purpose classroom of the Department of Physics:

"Xiao Yao is the youngest associate professor at Danfu University. He has unique research on optics at a young age!"

"I did a lot of work in order to make Da stay with us!"

After listening to Na Rulong's introduction, Mingyang began to think, and also became very interested in this associate professor whom he had never met before.

soon.

The two came to the door of the classroom.

On the podium, a young man in his thirties, wearing glasses but with an elegant appearance, was giving a lecture with great excitement. Most of the students in the audience were listening attentively, but there were also a few black sheep who fished in troubled waters in the classroom.

Na Rulong coughed after entering the classroom, and all the students found that the principal came in with a young man.

When Mingyang completely entered the classroom, a small number of the students below reacted.

"Fuck, it's Mingyang!"

"Why is she here?"

"Isn't that what it looks like up close?"

The person who spoke was a boy, and there was obviously some sourness in his words!

When Yao Wei heard the commotion below, he wanted to scold him, but when he saw his classmates looking towards the classroom door, he looked aside suspiciously.

"Principal, why are you here!"

"Haha, I'm bringing a distinguished guest to see you!"

Yao Wei put down the chalk in his hand, wiped the dust from his hands on his pants, and hurried over.

"Who is this?"

"Come, let me introduce to you, this is..."

"Professor Yao, this is Mingyang! Chairman of Tianyao Capital!"

Before Na Rulong could introduce it, the students below had already started to answer first.

Mingyang touched his nose. It seemed that he was really a celebrity!

Na Rulong laughed, "Yes, this is Ming Yang!"

Yao Wei didn't know Mingyang, and he didn't know much about Tianyao Capital, but seeing how excited the students below were, he guessed that the other party must be a big shot.

Mingyang took the initiative to extend his hand, "Professor Yao, nice to meet you!"

"Hello, Ming...Ming Dong, nice to meet you!"

The two of them knew each other, Na Rulong said:

"Xiao Yao, let's go out and have a chat!"

Yao Wei said with a troubled face;

"Principal, I still have classes..."

Mingyang has a better impression of Professor Yao, who doesn't know how to adapt. If others hear Yao Wei's answer, they will definitely feel unhappy, but Mingyang is not an ordinary person. For a soul engineer like Yao Wei, he can still face capital. Just saying that there are still classes is enough for Ming Yang to respect him!

Na Rulong glanced at Mingyang helplessly, but Mingyang laughed.

"Professor Yao doesn't want to explain why I'm sitting in with Na Lao, right?"

Yao Wei nodded and said seriously;

"Of course you are welcome, and I hope you can give me some feedback after class!"

Rulong was naturally happy. What principal wouldn't love a person like Yao Wei who concentrates on academics? It's just that the other person's emotional intelligence...

Mingyang and Na Rulong walked to the back of the classroom, and the students in the seats paid attention.

Yao Wei on the desk slapped the chalk eraser hard and said, "Let's start class now!"

The two people who had just sat down were almost startled. Na Rulong explained:

"That's what this little Yao is, I hope you don't mind!"

Mingyang shook his head, "Why would I mind!"

Afterwards, the two listened intently to Yao Wei's lecture.

After listening for a while, Mingyang felt a little drowsy. If someone who is not a professional in this field wants to understand what Yao Wei is talking about, it is like listening to a book from heaven.

Mingyang's eyelids became heavier and heavier, and finally he fell asleep.

This made the dragon on the side laugh and cry!

You were the one who said I was observing, but you are still the one sleeping in class now.

Fortunately, there was not much time left in the class. Yao Wei's announcement of the end of get out of class also woke up the drowsy Ming Yang, who subconsciously wanted to stand up and say hello, teacher!

As quick as a dragon's eyes, it pulled Mingyang back

"Director Ming, don't get excited!"

"ah?"

Mingyang cursed in his heart, damn, and almost made a fool of himself. Fortunately, Na Lao was there, otherwise this old face would have been completely embarrassed here today.

In fact, it was Mingyang who thought too much, because the two of them were in the last row, and the students were all listening intently and did not pay too much attention to the movements in the back row. It is indeed a Danfu University, and the atmosphere in class is so good!

After class, the students stood up one after another, but had no intention of leaving the classroom. Instead, they surrounded Ming Yang and Na Rulong.

Among them there were many good-looking female classmates who said:

"Dr. Ming, can you add me on WeChat?"

"Yes, yes, I am your idol!"

"Don't squeeze me, I came first!"

Na Rulong coughed with a black line on his forehead and said;

"How unbecoming! Go back to the dormitory after class!"

Rulong was the principal, so this action naturally worked and the students dispersed one after another.

When the students approached, Yao Wei came over with teaching materials in his hand.

"Xiao Yao, you taught this lesson well. I tried to keep you in school against all the odds. It seems to be the right thing to do!"

Yao Wei lowered his head and said with a face of shame:

"The students just followed the pictures and talked about the contents in the textbooks!"

"Okay, Xiao Yao, don't be modest. Director Ming is here this time because he is interested in your photolithography project. Come and give it a good talk!"

"Lithography project?"

Yao Wei looked happy, he just had an idea!

When he first told this idea to the old academics at the school, they were all mocking himself and saying that he was talking nonsense.

Could it be that my Bole is here?

Mingyang said with a smile on his face:

"Professor Yao, please tell me what you think!"

Yao Wei took a deep breath and said:

"The most advanced model of our domestic lithography machine in Longguo is SSA600/20, which can realize the 90nm process. The domestic lithography machine can support up to 55nm nano-level process, which is the lowest performance in the world!"

"This is mainly due to the international blockade of our Longguo lithography technology, which has prevented our domestic lithography technology from breaking through!" "It is well known that the lithography machines on the market are all miniaturized. The most important reason for their miniaturization is In order to export, why don’t we do the opposite and make it big if we want to do it!”

The two became interested, and after sitting down with Na Rulong, Mingyang continued:

"Tell me carefully!"

"Okay, then I'll explain it in an easy-to-understand way!"

"It is very difficult to miniaturize any optical device. We can think of light in different wavelength bands as a bunch of balls of different sizes."

"The lithography machine requires a filtering device to obtain balls of a specific size. The great thing about ASML is that they can find 7-nanometer balls in a light path of several meters. The ones that are not needed are automatically filtered!"

"But all we have to do is..."
