caption: In this picture, we see a group of children are standing. They are smiling and they might be posing for the photo. Some of them are raising their hands. Behind them, we see a white color board or a projector screen. At the bottom, we see the floor. In the background, we see a wall and the glass windows from which we can see the trees and the sky. In the right top, we see a photo frame is placed on the wall. On the left side, we see a white color object which looks like a door. Beside that, it looks like a board.
