立秋｜人间朝暮，一味知秋

The Beginning of Autumn: Days Drift By, Autumn Comes Near

核心科普 Core Science

立秋，是二十四节气中的第十三个节气。

The Beginning of Autumn is the 13th of China's 24 solar terms.

从这一天开始，秋高气爽，月明风清，气温逐渐下降。

From this day forward, the air turns crisp and refreshing, moonlit nights are breezy and clear, and temperatures gradually drop.

立秋之后仍有一"伏"，"秋老虎"依然存在，大家仍要注意防暑。

The sanfu (the hottest period of summer) lingers on after The Beginning of Autumn, and the so-called "autumn tiger" – a spell of scorching weather – often makes its presence felt, so caution against the heat is still advised.
