The image shows a group of four young people standing in front of a blackboard in a classroom. The blackboard has Chinese characters written on it in pink and green. The numbers "106" are written in large, bold letters at the top of the blackboard. Below the numbers, there is a list of numbers written in Chinese characters. The people in the image appear to be students, as they are standing in a line and are looking at the board attentively. The girl on the left is wearing a gray t-shirt with a cartoon character on it, the boy in the middle is wearing black shorts, and the boy on the right is wearing red t-shirts. All four people are wearing casual clothes and are standing close together.
