White Dew is the fifteenth solar term, beginning around September 7th or 8th and ending around September 22nd or 23rd, when the Sun reaches the celestial longitude of 165°. It marks the definitive boundary between lingering summer heat and advancing autumn chill—no longer a gradual cooling, but a palpable coldness. At dawn, crystalline dewdrops glisten on grass and leaves, a tender whisper from moisture-laden air in the long, clear nights. Daytime may still hold a faint echo of summer warmth, but once the sun sets, autumn's chill creeps in from all directions, urging people to don extra layers and heed the deepening night air.
Agriculturally, White Dew is a prelude to harvest and a prologue to sowing. In the northern fields, sorghum turns deep red and millet bows low, while cotton bolls burst white as clouds. In the south, late-season rice enters its critical earing and flowering stage, demanding careful irrigation to fend off the sudden "cold-dew wind" that can blight the crop. Autumn droughts and floods may alternate without warning, so farmers race against time—reaping early-maturing crops in fair weather while simultaneously preparing soil for winter wheat. As the old saying goes, "Plant wheat on the highlands at White Dew, and on the flatlands at Autumn Equinox"—every furrow of earth becomes a stage for a race with the seasons.
Culturally, White Dew carries traditions steeped in harmony with nature and self-care. In Jiangnan, the custom of brewing and sipping "White Dew tea" prevails—tea leaves picked at this time, having endured the scorching summer, yield a mellow, balanced flavor, neither as tender as spring tea nor as bitter as summer brew, making it the perfect companion for autumn afternoons. There is also the refined practice of "gathering morning dew"—collecting droplets from leaves at dawn to use in herbal remedies or as eyewash, for ancients believed it could sharpen vision and prolong life. In many households, silver ear fungus and lily bulbs are stewed into nourishing soups to moisten the lungs and counter autumn's growing dryness. In Fuzhou, Fujian, longan fruits are a must-eat on White Dew day, believed to "tonify the body against the cold." In the Jiangsu-Zhejiang region, families brew mildly sweet White Dew rice wine, warm and soothing against the evening chill. These humble rituals, woven into daily life, speak of a profound respect for nature's rhythms and a tender care for bodily well-being.
The beauty of White Dew lies in its unhurried grace—it lacks the hesitation of Early Autumn and the finality of Autumn Equinox. Instead, it quietly infuses every dewdrop with the essence of autumn, allowing all things to settle in the growing coolness. It reminds us that summer's fervor must eventually fade, and autumn's tranquility is but life's gentle turn toward ripeness and introspection. At this season, one might rise early to watch the dew glisten, or lie awake at night to hear the wind whisper—receiving, with quiet gratitude, the clear and profound rhythms of this unfolding season.
