The president came forward and knocked on the courtyard door. "Mr. Fu, are you at home?"

"Yes, come in." An old, hoarse male voice came from the courtyard,

"Come on, Professor Xia, this way, please," the Dean opened the door and took Xia Wanyuan to go inside. "Mr. Fu is now 90 years old, and he is the oldest person in our research institute. If he doesn't know anyone, he really can't help it."

"Thank you," Xia Wanyuan nodded to the dean,

The door of the room was opened, and there was a white haired old man sitting in the living room. The Dean bent over the old man and said, "old man, this is Professor Xia of Qingda. She has something to ask you."

Xia Wanyuan bent slightly towards the old man to show his respect. When he looked up, Xia Wanyuan found that the old man looked at himself with a very strange look.

"Dean, if you have something to do, go ahead. I can do it myself."

"OK, OK, I'll ask other researchers to come and pick you up later." The headmaster has too many things to do every day. He can't wait to sit with him here.

When the president left, Xia Wanyuan came to Mr. Fu, "does Mr. Fu know me?"

Although Mr. Fu is old, his eyes are very clear. He stares at Xia Wanyuan's face with shock and bewilderment. "What's your name?"

"Xia Wanyuan."

"How old?"

"This year 23"

"23", Mr. Fu murmured, as if he didn't believe it at all. He wiped his eyes with his hand and looked at Xia Wanyuan again, "23..."

"The old man knows my grandparents? Do I look like my grandparents? "

Mr. Fu shook his head. "It's all right. I admit my mistake."

Xia Wanyuan saw that the old man didn't want to say more, and she didn't continue to ask. Instead, she handed the paper in her hand to Mr. Fu, "Mr. Fu, can you help me to have a look, what does the pattern mean?"

At the moment when the paper in Xia Wanyuan's hand unfolds, the old man's face changes slightly. He stares at Xia Wanyuan tightly, "where did you find these?"

Xia Wanyuan is a person who respects the old scholar very much, but it doesn't mean that she has to completely comply with each other. "Can you tell me first, old man, whether these lines have any special meaning?"

Mr. Fu's eyes fell on those strange lines. After a while, he turned his head and said, "you go. I haven't seen these things."

Xia Wanyuan's eyebrows wrinkled slightly. She could see that Mr. Fu must know something, but he was also afraid of something,

Xia Wanyuan knew that she couldn't eat hot tofu in a hurry. She stopped asking more questions, but nodded, "thank you, old man, I won't disturb you."

With that, Xia Wanyuan put the paper away and turned to leave.

As Xia Wanyuan's back disappeared at the door, Mr. Fu's eyes gradually became deep,

Of course, he has seen those lines, but it has been nearly 70 years since he saw them,

He knew that these things would reappear one day, but he didn't expect it to happen so soon.

After leaving the Institute, Xia Wanyuan confirmed that Mr. Fu must know something inside. She called Shen Qian,

"You can help me to check all the experiences of Mr. Fu of the Institute of cultural studies. You should be very detailed and specific."

"OK, I'll do it right away."

After hanging up, Xia Wanyuan folded the paper and put it in his bag, then called junshiling.
