As the dawn just reached the eaves of the teaching building, it first fell on the outer wall of the cafeteria. Those rows of light gray metal-glazed exterior tiles, like silver foil kissed by the morning mist, are not ostentatious but have their own gentle luster spreading out. The light gray metal-glazed exterior tiles still maintain a composed posture. The glaze surface gently reflects some light, preventing the wall from being overly hot and instead giving off a touch of freshness. 

The light fell on the walls, giving the pale grey a warm yellow halo. The texture of the metal glaze became more pronounced in the darkness, and the brick surface seemed to be sprinkled with a layer of fine starlight, gently outlining the shape of the dining hall.
