group of people, mostly young men, standing on a green lawn. There's a white tent in the background. Most of the young men are wearing blue school uniforms with black skirts or trousers. Some wear other colors like orange or yellow. One adult man is wearing a black long-sleeved shirt and blue pants with white stripes. He dances with a boy in a yellow shirt and blue jeans. The lawn appears well-maintained. There are trees in the background, and some buildings can be seen in the distance.
