This year's "San Fu" only lasted for 30 days, breaking the record of 40 consecutive days of "San Fu" over the past 10 years.

On July 20th, this year's "Sanfu" officially began, with many parts of the country entering a period of sustained high temperatures, typically represented by "sauna days." Experts say that from 2015 to 2024, the duration of "Sanfu" was 40 days for 10 consecutive years, but this record will be broken this year. The length of "Sanfu" this year is only 30 days. "Sanfu" is the hottest and most humid period of the year. The heat of "Sanfu" is known as "sultry heat" in folk culture, which is hot and moist, like being in a steamer or oven. Experts advise the public to stay hydrated, have a regular sleep schedule, maintain a balanced diet, and take precautions to prevent heatstroke and lower body temperature during the upcoming "steaming and boiling" period.
