"Three volts" refers to the first, the middle and the last, about the period from mid July to mid August. After the summer solstice, although the day is shorter and the night is longer, the day is still longer than the night, the heat absorbed by the ground is still more than the heat emitted every day, and the temperature near the ground is higher day by day. By 'three volts', the ground absorbs almost more heat than it emits, and the weather is hottest. In the future, the heat absorbed by the ground will be less than the heat emitted from the ground, and the temperature will slowly drop. Therefore, the hottest time of the year usually occurs in the summer solstice.

From the third 'Geng' day after the summer solstice, the first (10 days), the middle (10 or 20 days) and the last (10 days from the first Geng day after the beginning of autumn) are the hottest days of the year.

V, divided into the first, the middle and the last, is called three volts. Three volts is the hottest period of the year, because the night is shorter and the day is longer, and the sun is close to direct. But the summer solstice is not the hottest time, because at this time, the heat absorbed by the ground emits a large part of it at night. However, it absorbs more heat and dissipates less heat every day. It's getting hotter every day. It's about 20 days to three volts. It's the hottest day.

The third day is the first day from the summer solstice to the third day, the fourth day to the fifth day, and the first day to the second day after the beginning of autumn. Each day is separated by 10 days, and the average number of days is not fixed. There are 4 days between the summer solstice and the beginning of autumn, the average is 10 days, 5 days, and the average is 20 days.

Fu, is the meaning of summer. From the summer solstice, the days start to get shorter and the nights start to get longer. There is a cold factor lurking in the middle of the heat. It is very scientific to call it "Fu" at the beginning.
