The morning mist has not yet dissipated, and the red vintage exterior bricks already exude a warm luster in the hazy light. The brick surface has a frosted texture due to the accumulation of time, and there are a few light gray marks embedded in the brick joints, like fine lines etched by time. The sunlight penetrates the mist, giving the red bricks a soft glow, changing the color from deep red to light vermilion, with distinct layers. The outline of the teaching building becomes more stable under the outline of the red bricks, blending with the crisp early morning reading sounds in the campus, adding a lively aroma of books to the vintage brick surface.
