five people dressed in white uniforms with different colored belts standing on a concrete platform in front of a building. The building has a modern design, with a yellow geometric pattern on the upper section and a red awning over the platform. Two of the people have red belts, one has a black belt, and two have no belts. They appear to be practicing martial arts, moving their arms and legs in coordinated motions. There are two green trash cans on the platform and a small door on the left side. The area in front of the platform is unpaved with exposed dirt and small rocks.
