The image shows a classroom with a blackboard in the background. On the blackboard, there is a diagram of a network of interconnected lines and dots, representing the interconnectedness of the network. The diagram is accompanied by Chinese characters and illustrations.

In the foreground, there are two people, a man and a woman, standing in front of the black board. The woman is holding a microphone and appears to be giving a presentation to the man. The man is wearing a blue shirt and glasses and is smiling at the woman. Behind them, two other people can be seen sitting at a desk, and there are blue chairs and a white fan in the room.
