Street basketball 2008-2018 has ten years of history in China. Excellent players and teams have emerged all over China. Dongdan Sports Center has been an indispensable basketball holy land in the sports history in the past decade. But all have changed after 2014: Suspension of all street basketball activities, dissolution of teams and the arrival of We-media era seemed to dismember this niche activity. In July 2018, a group of children with dreams played a game with a time-honored New York DYCKMAN League in the name of Dongdan, the birthplace of Chinese street basketball. New York, as the birthplace of outdoor basketball, had a fierce cultural and sports collision with these children. This was the most thought-provoking point of the film besides the arena.
