Aerospace photography enthusiast Guan Tianyu shields his photographic gears from direct sunlight while waiting to capture the moment of blast-off of the Long March-7 Y4 rocket, carrying Tianzhou-3, on top of a hill in Wenchang City, south China's Hainan Province, Sept. 20, 2021. The Long March-7 Y4 rocket, carrying Tianzhou-3, blasted off from the Wenchang Spacecraft Launch Site on Sept. 20, 2021, right in front of numerous cameras erected by photography enthusiasts with special interest in astronautics. Enchanted by the sophisticated launching technologies and the tremendous challenges of shooting the launching rockets, these young yet enthusiastic souls have been trying their best to witness and record those overwhelming moments with their cameras. By actively sharing what they have captured to others, they are also helping more of their kind to understand the development in the course of astronautics in China. (Xinhua/Pu Xiaoxu)
