The image presents a classroom scene in Daxing District, China. A male individual, wearing a light blue short-sleeved shirt and dark trousers, stands centered, actively writing with chalk on a large green blackboard. He holds an open book or binder in his left hand. The blackboard behind him is densely covered with mathematical notation, including Cartesian coordinates, a circled distance formula, and set theory exercises. The male is currently writing "Given any two points..." on the lower right section of the blackboard. In the foreground, the back of a female student's head and shoulder are visible on the left. She has dark, curly hair and wears a floral-patterned sleeveless top, seated at a light-colored wooden desk. On the desk in front of her are a red marker, a black smartphone, and a small patterned pouch. An open notebook is present on the desk in the immediate foreground. The classroom features a white, acoustically tiled ceiling with six visible recessed fluorescent light fixtures providing overhead illumination. The walls are white. A white wooden podium with a light gray top is positioned in front of the blackboards. The floor has a lighter wooden section near the front transitioning to a darker gray. On the right wall, two signs with Chinese characters are mounted: a small blue and white sign and a red and white sign below it. Light-colored wooden desks and chairs are arranged in rows, with visible Chinese characters inscribed on the back of one chair.
