dog days refer to the days when the temperature is the highest, humid and muggy in a year between slight heat and summer. "Fu" in "dog days" refers to "Fu evil", that is, the summer evil in the so-called "six evil". "Three volt" lasts for 40 days, of which "medium volt" lasts for 20 days. The time of entering the ambush is not fixed every year, and the length of the middle ambush is also different. It needs to be calculated by looking up the calendar. Simply use the four word formula of "three Geng" in the summer solstice to express the date of entering the ambush, that is, from the third "Geng" day after the summer solstice, the first ambush is 10 days, the middle ambush is 10 days or 20 days, and the last ambush is 10 days. In ancient China, the "Ganzhi Jiri method" was popular. 60 groups of different names made of 10 heavenly stems and 12 earthly branches were used to remember the days. They were recycled. What has the word Geng on the Yellow calendar is Geng RI.
