A classroom in Jiangjin, China is depicted, featuring a female instructor and two students. The instructor, wearing a dark padded coat and glasses, stands at the front, holding a microphone or pointer in her left hand and gesturing with her right hand towards an interactive whiteboard. The whiteboard displays both handwritten geometric diagrams on its left section and a projected presentation titled "Plane geometry element representation" on its right section. This presentation illustrates various geometric concepts with diagrams and descriptive captions. Above the whiteboard, a white projector is mounted on the wall, alongside a black speaker to its right. Two linear fluorescent light fixtures illuminate the white ceiling, from which a white three-bladed ceiling fan is suspended. In the foreground, two students are visible from behind, seated in blue chairs at light-colored desks, both wearing dark padded coats and facing the instructor. The student on the left has short, dark hair, while the student on the right has dark hair styled up or covered.
