Q: does the summer solstice begin to count volts? A: No, the day when the voltage counting starts is the third day after the summer solstice.,
and "Fu" mean that Yin Qi is forced to hide underground by Yang Qi. There are three volts every year, and the dog days are the hottest time of the year. From the summer solstice, according to the arrangement of GaN and Zhi Ji days, the third Geng day is the first ambush. The fourth day of Geng is the middle ambush, and the first day of Geng from the beginning of autumn is the first day of the last ambush and the last ten days.and
during the Qin and Han Dynasties in China, the saying of "five elements generate each other and overcome each other" prevailed. It is believed that the hottest summer day belongs to fire, while Geng belongs to gold. Gold is afraid of fire burning (fire conquers gold), so on Geng day, gold will hide. Therefore, it is stipulated that from the third Geng day after the summer solstice, it is the first volt (10 days), from the fourth Geng day after the summer solstice, it is the middle volt (10 days in some years, 20 days in some years), and from the first Geng day after the beginning of autumn, it is also called the last volt (10 days), which is generally called the third volt.and
when there are four Geng days between the summer solstice and the beginning of autumn, the medium voltage is 10 days, and there are five Geng days, it is 20 days, so the medium voltage to the last voltage is sometimes 10 days, sometimes 20 days, while the "first voltage" and "last voltage" are 10 days.
