White Dew customs include eating longan in Fuzhou, Fujian, and a preference for White Dew tea in Nanjing, Jiangsu, as reported by the regional culture account cited below. These are local food practices, not medical treatments.

Calendar position and meaning

White Dew precedes the Autumn Equinox and Cold Dew. Dew is liquid water, not frost. Its presence depends on local surface cooling and moisture rather than the calendar name alone.

Regional customs and their evidence

A People’s Daily culture feature attributes eating longan to Fuzhou, Fujian, and a preference for White Dew tea to Nanjing, Jiangsu. These named examples should remain regional.

The seasonal word “autumn” here follows the traditional Northern Hemisphere calendar. The Hong Kong Observatory relates many term names to ancient central Chinese weather and agriculture. Local weather and plant development may differ; Southern Hemisphere seasonal timing is reversed.
