This unglazed exterior wall tile then becomes a "weaving machine" of light and shadow - the light beige and grayish-brown tones are like crushed linen, spreading out on the tile surface as a gentle base color. And the smooth vertical lines on the tile body are the lines drawn spontaneously by wind and fire in the kiln: some are fine and dense like the weft and warp of fabric, causing the light to break into pale gold star-like specks on them; some are wide and sparse like the folds of clouds, and the dark tones then sink along the lines into a hazy gray haze. 

The contrast of light and shade in the lines is like the brushstrokes of time. When the black-framed glass reflects the green plants outside, the warm tones of the clay blend seamlessly with nature, carrying the lightness and sharpness of contemporary design - each brick is a "notebook of earth and light", allowing the building to breathe with the poetic interplay of light and shade on a soft background.
