"A high-definition image, but in gray tones, of an old, desolate classroom. The wooden benches are empty and dusty, and the weathered blackboard has faded words that haven't been erased in a long time. In the corner of the room, a pile of old books and educational materials is covered in cobwebs. The only window in the room is covered in dust, letting in little light. The image conveys a strong sense of neglect and the absence of progress in skill development of oral communication in the educational field., blur haze
