立秋 — Start of Autumn — arrives with one of Chinese culture's most poetic observations: 一叶知秋 — "from a single falling leaf, know that autumn has come." The first leaf to fall tells the whole story. The heat is not gone. Summer still burns. But something has changed. The Chinese could feel it: direction. This is the genius of 二十四节气 — noticing direction before it becomes obvious.

One leaf tells the whole story. The direction has changed, even before the season looks different.

Notice the one leaf. A change has begun that the whole season will confirm. You noticed first.

This wallpaper isn't magic. It's a small visual anchor — a reminder of the mindset you want to carry with you today. Think of it as a personal symbol rather than a supernatural guarantee.
