The image shows a classroom with a blackboard in the background. On the blackboard, there are various illustrations and text written in Chinese characters. In the center of the room, there is a man standing and holding a microphone and speaking to a group of students who are sitting at desks. The students are wearing casual clothes and appear to be engaged in a discussion. There is a projector screen on the left side of the image and a desk fan on the right side. The room appears to be well-lit with natural light coming in from the windows.
