The image shows three young children standing in a classroom. The boy on the left is wearing a yellow t-shirt with the words "Subway Line" printed on it. The girl in the middle is wearing glasses and a pink shirt with a star on it, and the girl on the right is wearing an ID card. All three children are holding up small white boxes with colorful designs on them. They are smiling and appear to be proud of their work. In the background, there is a bulletin board with Chinese characters and posters.
