When will it enter the volt?

Burial is a folk saying in our country, and it is unknown when it originated. The so-called "crouching" means entering the "dog days", and "crouching" means hiding, because the yang is rising and the yin is forced to hide underground by the yang. Dog days are also the hottest time of the year.

However, regarding the calculation method of dog days, there is a saying that "there are three Geng days in summer", that is, the third Geng day in Xia Hou is the first day of setting. This is also the crystallization of the wisdom of the ancients. It is said that during the Qin and Han Dynasties, the saying that "the five elements were born together" prevailed, and the hottest time was summer, which was the fire in the five elements.

According to the agricultural proverb handed down by the ancients, "cold is in March 9th, heat is in the upper middle", in which the upper middle is generally the hottest period, so July 2nd1to August 9th is often the hottest.
