The image shows a classroom scene with three students sitting on the floor in front of a whiteboard. The student in the center is holding up a green sign with Chinese characters written on it. He is wearing a black t-shirt and glasses and has a big smile on his face. Behind him, there is a young woman standing and holding up the sign. She is also holding a piece of paper with the same Chinese characters as the student on the left. On the right side of the image, there are two other students, one wearing a blue shirt and the other wearing a yellow shirt. They appear to be engaged in a conversation. The whiteboard behind them has some writing on it, but it is not clear what it says.
