When the morning mist rolls over the foot of the mountain, the old-fashioned blue-tiled exterior walls are enveloped in a refreshing coolness, standing quietly among the greenery. The surface of the tiles is a deep bluish-gray color, with a smooth and silky texture like sandpaper. Occasionally, moss grows shallowly in the gaps between the tiles, spreading out a soft greenish hue. 

As the sun rose higher, the fog dissipated, and the texture of the blue bricks became increasingly clear. Each brick was neatly arranged in an orderly manner, and the traces of time on the brick surface were clearly visible, either the fine lines left during the firing process, or the faint marks left by the wind and rain, all adding to the sense of vintage that was even more profound. As dusk fell, the sunset painted a light purple halo on the blue bricks. The brick color gradually deepened, transitioning from bluish-gray to dark green, blending seamlessly with the gradually darkening sky.
