Autumn Begins

The beginning of autumn is established. The wind shifts, and the leaves begin their slow descent.

Autumn does not arrive with a bang. It arrives as a single cool morning after weeks of heat, a slight change in the angle of light, a dryness in the air that was not there before. The calendar calls this the beginning of autumn, but the trees are still green and the cicadas still sing. The wisdom of this term is that endings begin long before they are visible. The turn has already happened. You just can’t see it yet.

Liqiu, the thirteenth solar term, arrives around August 7 to 9 when the sun reaches 135° of celestial longitude. It marks the official beginning of autumn, though in much of China the heat of summer persists — a phenomenon known as "autumn tiger" (秋老虎, qiū lǎohǔ). This term reflects an astronomical reality rather than an immediate weather change. Three pentads describe cool winds arriving, white dew appearing in the morning, and cicadas beginning to sing their autumn song. This cicada's seasonal song is different from its summer call — a shift in pitch and rhythm that attentive ears can detect. These are subtle signals that the season is turning, available to those who pay attention. In agricultural terms, Liqiu signals the beginning of the autumn harvest. The early-ripening crops are ready, and the fields must be prepared for the winter wheat planting. This term carries a sense of urgency beneath its calm surface: the window for harvest is limited, and the work must be done before the weather turns. This wisdom of Liqiu is the wisdom of timely action — knowing when to gather what you have grown.

Liqiu’s official date follows solar longitude, while “autumn tiger” describes a recurring regional spell of late heat in parts of China. Harvest timing differs with crop and latitude. The term therefore teaches temporal judgment: use the calendar as a prompt to look, not as a substitute for local observation.
