In Chancheng District, China, at night, a group of people are engaged in a coordinated physical activity outdoors. They are standing in a paved plaza, possibly a park or public square, surrounded by lush trees. The scene is illuminated by bright streetlights and possibly decorative lighting, casting strong shadows on the ground. Many individuals are wearing casual athletic attire, such as t-shirts and pants or shorts, and most are facing the same direction, with their arms raised. In the background, a large, illuminated, wing-like structure is visible. A red pole with lights is also present. The overall impression is of a communal exercise class or dance performance taking place in an urban outdoor setting after dark.
