Wang Yihan, a fifth-grade student at the Yuxin School Attached to Capital Normal University, said: "The astronauts' experiments really intrigued and surprised me. I have great interest in spaceflight and would like to take part in our country's space exploration program in the future."

Vincent Wong Wai-shing, deputy principal of Hong Kong's Pui Kiu College, said after watching the lecture that the event gave Hong Kong students an opportunity to communicate with the astronauts while stimulating their interest in space and science.

"It also helped to enhance their sense of national identity as they saw the rapid development of our country's space technology," he said.
