Nan Rendong was called “the Father of China's Sky Eye”.

Born in 1945 in Jilin Province, Nan showed great interest in science as a child. 27. Later he got a chance to study abroad. Many foreign scientists wanted him to stay, but Nan refused. “My country needs me,” he said when returning to China in 1994.

29. On 11 January 2020, FAST opened officially. Sadly, Nan passed away in 2017 before seeing its first big discovery. But his spirit lives on. A young engineer working on FAST said, “30. He taught us that true success needs both dreams and perseverance（毅力）.”
