In a well-lit classroom or lab, a group of students wearing white lab coats is listening to a female instructor, also in a white lab coat, as she stands in front of a large screen displaying a diagram of the human heart. The screen's text is in Chinese. The instructor is gesturing with her hands as she speaks. A counter with equipment runs along one side of the room, while student desks and chairs are arranged in rows facing the screen. The environment suggests a medical or scientific education setting.
