A modern-inspired kelp drying technique developed by Xie Yushu based on her previous life knowledge. The core steps are: sunlight (soft morning/afternoon light is better than intense midday sun; partial shading at noon), ventilation (elevating bamboo trays or placing stones underneath for airflow), and frequent turning (three times per day: morning, noon, and evening). She shared this method with Hong San to improve kelp quality for her business.
