From 1994 to 2015, Nan led his team across China’s mountains to find the perfect location. Finally, they chose a location in a Guizhou Province. During the process of building FAST, Nan and his team faced lots of difficulties, including bad weather, technical problems, and limited funding(有限的资金). There were times when the project nearly stopped, but Nan never lost heart and always found his way forward. When completed in 2016, FAST became China’s most important astronomical achievement. It can pick up weak radio signals from faraway in the universe, helping scientists search for stars, black holes and even the origin of the universe. Nan passed away in 2017 because of cancer, but his influence has continued. An asteroid(小行星) was named after him in 2018. The Chinese government awarded him the national honor of “People’s Scientist” in 2019.
