Noon.
At Old Zhang's villa.
Zhang Ye was watching a soccer game by himself.
"Run!"
"Dribble past him!"
"It went it! It's a goal!"
"Beautiful play! Score another one!"
"The Chinese team is quite good this year!"
At this moment, the door behind him suddenly opened.
Zhang Yuanqi and Ma Fei led Professor Sun and the others in.
When Ma Fei entered the house, she shouted excitedly, "Teacher Zhang! Teacher Zhang!"
Zhang Ye turned around and said, "You're back? How was it?"
Professor Sun came up to him. "Fellow Zhang, long time no see."
Zhang Ye was startled. He stood up and said, "Oh, Professor Sun, why are you here?"
Ma Fei said, "Ah, so you two know each other?"
Professor Sun said, "We both had appointments in the Chinese Academy of Sciences, so we've met once or twice before."
