With the rapid development of China’s economy, enormous technological and infrastructure projects have mushroomed across the country one after the other. Behind these incredible feats of engineering are numerous craftsmen with unrivalled skills and knowledge. In a bid to better understand the secrets behind China’s technical marvels, CGTN followed these master craftsmen to unveil the stunning work they have contributed towards the Chinese dream! FAST (Five-hundred meter Aperture Spherical Radio Telescope) is the world's largest radio telescope, and entered operation on September 25, 2016, in a mountainous region of southwest China's Guizhou Province. As large as 30 football pitches, the dish is made of 4,450 large reflector panels, work on which began in 2011, with the mission being to further explore space and look for extraterrestrial life. Zhou Yonghe is a leading craftsman who was charged with the task of accurately fitting the last of the 4,450 panels into the center of the dish. Together with his colleagues, Zhou installed more than 400,000 mini reflector panels, finishing his task one month ahead of schedule.
