"Three Volts" is introduced in detail:

"Three volts" refers to the first, middle and last three volts, which is about mid-July to mid-August. After the summer solstice, although the days are getting shorter and the nights are getting longer, the days are longer than the nights in a day. Every day, the ground absorbs more heat than it emits, and the temperature near the ground is getting higher every day.

During the "three volts" period, the ground absorbs almost more heat than it emits, and the weather is the hottest. After that, the heat absorbed by the ground began to be less than the heat emitted by the ground, and the temperature gradually decreased. Therefore, the hottest time of the year generally appears in the "three volts" summer solstice.

"Three Gengzi" is the third Gengzi Day, which is recorded by the calendars of cadres and branches. Such a day has long been fixed. You just need to calculate the third Geng day on the calendar, and start looking for it from the solstice in summer, and you can find the day when you enter the head, which is only 10 day.
