On the group photo, there is a young couple, holding a child.

"Yes, this is my father, this is my mother, this is me!"

Luo Yang saw that Tang Yuyan in the photo was just a two- or three-year-old child, with a childish look and a very cute look.

I secretly thought to myself, if I had died twenty years ago, it seemed that it had happened not long after taking this picture.

However, why did Hao Hao die at such a young age, was there something wrong?

However, Tang Yuyan didn't say what the specific situation was, and she didn't want to ask too much.

"I'm sorry, teacher, I shouldn't have brought this up!"

Luo Yang comforted with self-reproach.

"It's fine. Tang Yuyan shook her head and returned to normal from her grief.

"Or do you want to tell me what is the matter?" Luo Yang said.

Tang Yuyan cleaned up her mood and said seriously: "Wait a minute, my grandfather wants to see you!"

"Your grandfather, do you want to see me?" Luo Yang was very puzzled.

"You'll know when you see it. ”

Tang Yuyan said and opened the WeChat of her mobile phone.

"Grandpa!"

"Good granddaughter, do you have classes in the evening?"

After a short greeting, Tang Yuyan said: "Luo Yang is here, grandpa, if you have anything to say, tell him yourself." ”

After speaking, the mobile phone was in front of Luo Yang.

"This is my grandfather, you just met. I used to be a math teacher at our school, and he has something to ask you. ”

Luo Yang pressed his mobile phone, and saw that in the WeChat video, an old professor with gray hair and kind eyebrows was looking at him with a smile.

"Hello, Grandpa!"

Luo Yang greeted politely.

The old man in the video looks a little similar to Tang Yuyan, and is about sixty years old.

The old man seemed to be in a hotel room, and Luo Yang guessed that he might be traveling somewhere.

"You are Luo Yang?"

Tang Yuyan's grandfather, Tang Xiude, a professor at Qianyanghe University of Finance and Economics, asked with some curiosity.

While looking at Luo Yang, he thought to himself that he just said that she would find a way to meet Luo Yang, but she didn't expect Yu Yan to invite someone to the dormitory.

"Yes, grandpa, my name is Luo Yang. ”

"The math genius that Yu Yan is talking about is you? is the person who went from failing math to becoming a math master all of a sudden, and solving math problems?"

Tang Xiude looked at the handsome boy in front of him, and said with doubts on his face.

secretly said in his heart, such a handsome boy could be a mathematical genius?

"Yes, it's me. ”

"Can you demonstrate the process of solving the problem again? Oh, it's not that I don't believe in your ability, it's just that such a complex historical problem was solved by you at once, and I really can't believe it. ”

Tang Xiude said.

It turned out that after Luo Yang answered Goldbach's conjecture in public in class, Tang Yuyan immediately told her grandfather the news.

Because my grandfather was also a professor of mathematics, he had a high prestige in the mathematics community.

She believed that her grandfather would be amazed.

Sure enough, after the grandfather learned about it, he was pleasantly surprised, and immediately explained to his granddaughter, and at the right time, invited Luo Yang over alone, and then demonstrated the problem-solving process in front of him, and he wanted to test Luo Yang in person.

You must know that Tang Xiude has been engaged in mathematical research for decades, and he has never solved Goldbach's conjecture.

He only studied the epidermis a little bit of a difficult problem like this, and it was difficult to carry it out anymore.

A difficult problem that such a mathematical authority as himself could not solve, but now it was solved by a college student, which made Tang Xiude listen to it, making him unable to believe it at all.

Therefore, seeing is believing.

Only when he saw Luo Yang solve the problem with his own eyes would he believe that all this was true.

"No problem. "Please Mr. Tang provide me with a blackboard. ”

After a while, Tang Yuyan brought Luo Yang a small blackboard.

Then, sitting on the sofa, leaning forward, curvy, waiting with anticipation for Luo Yang to demonstrate the problem-solving process again.

Whew......

Luo Yang got up and wrote on the small blackboard......

"His chalk writing is so good!"

In the video, Tang Xiude saw it and couldn't help nodding his head secretly.

Then, his eyes widened and he stared at Luo Yang motionlessly, for fear of missing every detail......

During Luo Yang's demonstration, Tang Xiude asked questions from time to time, asking him what was the basis for such an answer.

Luo Yang can answer every time, flawlessly!

A few minutes later.

That's it. ”

Luo Yang put down the chalk and waved his hand.

"Perfect!

In the video, Tang Xiude clapped his hands excitedly and praised.

It turns out that Goldbach guessed that was the case, why didn't I think of it?

Tang Yuyan also seemed to have forgotten the sad past, and stared at Luo Yang with adoring eyes.

"Young man, who taught you about mathematics?"

After thinking about it, Tang Xiude couldn't help but ask Luo Yang.

To be able to teach such a gifted teacher must be extraordinary.

"Teacher Tang taught. ”

Luo Yang pointed to Tang Yuyan, who was in a daze on the sofa.

"Uh, I'm ?......"

Tang Yuyan, who was shocked by Luo Yang's handsomeness and talent, came to her senses and hurriedly waved her hand to deny it.

Tang Xiude waved his hand and said:

"Well, I know best what level my own granddaughter is. She's not up to that level yet. Young people are proud to be too modest, and no matter what, I still admire you very much! I have made up my mind to make a friend of yours, and when I come back, I will come to you as soon as possible, and we will discuss the problems of mathematics. ”

"Young man, I'm traveling in Sanya, do you want me to bring you something?"

"No need, grandpa, you're too polite!" Luo Yang hurriedly excused himself.

"Alright then, goodbye!"

After speaking, Tang Xiude hung up the video call.

During this time, the school organized retired professors to go on trips, and Tang Xiude was also one of them.

There are still a few days left until the end of the tour. Tang Xiude couldn't wait to fly back now and communicate well with Luo Yang, and he decided in his heart that Luo Yang had forgotten his New Year's friend.

"Teacher Tang, your grandfather is so enthusiastic!"

Luo Yang smiled.

Sure enough, it's not a family, and it doesn't enter a family.

Tang Yuyan has a gentle personality and is empathetic, like a fairy.

I didn't expect her grandfather to be so reasonable and approachable.

Marrying a woman from such a family, regardless of material conditions, at least the family atmosphere is very harmonious and the spirit is very happy.

"Well, that's how my grandfather is, he was warm and kind to everyone. ”

Tang Yuyan paused, and then said as if she had made up her mind: "Luo Yang, I have a request, this request is quite special, I hope you can agree to it......"

"What do you want? ”

"I want to say...... Can you ...... When is my boyfriend?"

After saying this, Tang Yuyan felt that her whole face was feverish......
