Tan Rou came back from washing her hands and met Professor Zhong at the staircase.
The two of them looked at each other. Tan Rou laughed out loud. She crossed her arms and said to Professor Zhong, "It's been a few years since we last met. Why are you blind and lame, old classmate?"
"Old classmate?" Li Li opened her mouth in surprise. "Rourou, you're classmates with this old man? "
Professor Zhong narrowed his eyes and looked at her. Tears fell from his turbid eyes. "Long time no see, little girl. I didn't expect to meet you here."
Director Li, who came with him, was confused. "Mr. Zhong, is this really your old classmate?"
"I may not have good eyesight, but I'm not completely blind," Professor Zhong said unhappily. "How could I not recognize her?"
Tan Rou walked to Professor Zhong's side. "Why are you here? Is it because of the physics competition?"
