The teaching building with orange exterior tiles has already caught the first ray of morning light. The tile surface is a rich, warm orange color, with a delicate matte texture. The sunlight passes through the gaps between the tiles, coating each wall tile with a thin halo of light, making the entire building like a piece of honey soaked in morning light, emitting a gentle warmth in the tranquility of the early morning. 

As the morning reading bell rang, the campus gradually came to life, and the orange-colored brick walls became even more vibrant. The sunlight danced on the brick walls, and the color of the bricks changed in depth as it moved. The area near the window was illuminated brightly, emitting a soft orange glow, while the shaded areas were warm and deep orange, with distinct layers.
