Officer Yu shook his hand: "Professor Fang, sorry to disturb you."
Professor Fang nodded, indicating for them to sit down. He glanced at Officer Yu, then at Zhaxi, and said, "Go ahead, ask what you want."
Officer Yu got straight to the point: "Professor Fang, thirty years ago, you and Professor Zhou participated in the A-8 project together. I'd like to know the real situation of this project."
Professor Fang remained silent for a long time. He lowered his head, looking at the old photo album open on the table. Zhaxi glanced over; inside the album was a black and white photo of seven or eight people wearing White Gowns, standing in front of a laboratory building. On the back of the photo, a line was written with a pen: "A-8 project group photo, Spring 1991."
