group of people exercising outdoors in a plaza-like setting, likely near a beach. The sky is a deep purple, suggesting it is early morning or late evening. In the center of the group, there's a speaker, implying music or instructions are being played. The individuals are performing synchronized movements, possibly following an instructor, with their hands on their heads. A man in a white shirt and dark pants is walking toward the camera. In the background, there are palm trees, the word "DANANG" in large block letters, and a faint silhouette of a mountain. In the foreground, there's a sign that reads "VNPAY Cho cuộc sống đơn giản hơn." The ground is paved with patterned square tiles.
