Editor's note: From the launch of the Tianhe core module in 2021, to the "rendezvous in space" of the Shenzhou XVIII and Shenzhou XIX crew members in 2024, eight manned missions have been successfully completed during the key technology verification, in-orbit construction and application and development stages of China's space station. Behind the success of the Chinese space station lies the daily training undertaken by the astronauts.

Let's follow the lens of photographer Xu Bu and relive the remarkable moments from the daily training of astronaut crews.
