Fu Tou is the time node of "the third night in summer", that is to say, from the beginning of summer to the third night, it is the time for lodging.

Basic introduction

The dog days appear between midsummer and hot summer (from mid-July to mid-August in Gregorian calendar) and are divided into three days: morning, middle and evening. The dog days are characterized by high temperature, low pressure, high humidity and low wind speed. "Fu" refers to being forced to hide underground by the sun's spirit, and the date of three volts is determined by the date of solar terms and calendar.

Because every Geng day is 10 days apart, the stipulated time of the first day and the last day is 10 days. Because the third Geng day (early autumn) after the summer solstice solar terms appears sooner or later, the days of early autumn are long and short.
