A group of about 15 people are participating in an outdoor dance class at night. They are moving in unison, seemingly following a leader. The setting is a paved public square in front of a multi-story building with a large sign that reads "R&F SQUARE 富力次." The building is illuminated with bright lights. The environment is dark, but the area is well-lit, allowing for clear visibility. There are other people walking around in the background. The atmosphere seems relaxed and casual.
