There are five people visible in the image. They appear to be students, as indicated by their school uniforms. The individuals are wearing green shirts and white pants. One person is holding a book, while another is holding a backpack. The setting suggests an indoor environment, possibly a school or classroom, given the presence of a green structure with a sign that reads "CHI CHI" and a sign with the number "10". The overall atmosphere appears to be educational and orderly.
