The image shows two young children, a boy and a girl, sitting at a table in a classroom. They are both wearing blue t-shirts and have green lanyards around their necks. The boy is holding a small blue object in his hand and is looking at it with a curious expression. The girl is also holding a blue object and is smiling at the camera. In front of them, there are two large plastic buckets with red handles. The buckets are filled with a white substance, which appears to be a mixture of water and other ingredients. In the background, there is a blackboard with Chinese characters written on it.
