Core Viewpoint - The article discusses the characteristics and implications of this year's "Sanfu" period, which lasts for 30 days, highlighting the importance of proper summer cooling methods to cope with the heat [1][9]. Summary by Sections Sanfu Duration and Structure - This year's Sanfu period is shorter, lasting only 30 days, from July 20 to August 18, divided into three phases: initial Fu (July 20-29), middle Fu (July 30-August 8), and final Fu (August 9-18) [7]. - The number of days in the middle Fu is limited to 10 due to only four "Geng" days between the summer solstice and the beginning of autumn [7].
