There are three people in the picture: a Chinese mother, her junior high school student, and the teacher. They are having a gentle conversation. The background is a classroom. The teacher is smiling, with professional photography, positive lighting, full body shot, wide shot, with blank space around the picture, panoramic view, bright tones, a sense of youthful and sunny atmosphere. --ar 3:4 --v 7
