Colorful educational posters and a traditional chalkboard adorn the walls. A friendly teacher gestures at a smart screen, subtly hinting at modern tech. Potted plants and a small fan add to the comfortable atmosphere. Students wear light, summer uniforms and appear engaged in their studies.  --ar 2:1
