In a few days, it's the hottest season in the year. How many days does it have this year? In 2017, the number of days is 10, and the number of days is 20.
The time of ambush is not fixed every year, and the length of the ambush is not the same. It needs to be calculated by checking the almanac. It can simply use the four word formula 'summer solstice three Geng' to express the date of 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. The average time of 2017 is 20 days, starting from July 22 and ending on August 10.
According to the traditional calendar, the third 'Geng day' after the summer solstice begins to enter the 'head volt', while the first 'Geng day' after the beginning of autumn begins to enter the 'last volt'. If the summer solstice is far away from the 'Geng day', 20 days after entering the 'Fu', it has already passed the beginning of autumn, that is to say, the 'final Fu' begins, so the 'mid Fu' is only 10 days. If the 'Geng day' is close to the summer solstice, and the 'fall' is not reached after entering the 'Fu', then the 'Zhongfu' must be extended for 10 days, so that the 'Zhongfu' will last for 20 days.

In other words, when there are 4 g days between the summer solstice and the beginning of autumn, the median period is 10 days. If there are 5 g days, the median period is 20 days. It seems that the occurrence of the day of Geng will affect the length of the middle volt, so there are some years with 30 days of dog days and some years with 40 days of dog days.
Why do Zhongfu eat noodles? This custom began at least in the Three Kingdoms period. According to the Weishi spring and Autumn Annals, when he Yan 'laid down the sun eating soup cake, took the towel and wiped his sweat, his face was bright', people knew that he Yan's skin white was not covered with powder, but natural white. The "soup cake" here is hot soup noodles. (this article is exclusively compiled by WYH, editor of sihai.com. If you need to reprint it, please indicate the source and source.

Why do you eat hot noodles in hot days? In the book of Jingchu years of age by Liang zongbi of the Southern Dynasty, he said: 'in June, there is an eclipse soup cake, which is named Bi evil. "May is a bad month, and June is also on the side of the bad month, so we should also" fight against evil ". This is superstition. The new wheat is ground into flour to cook soup. After eating, the whole body perspires. The new grain is rich in nutrition. Perspiration can drive diseases. Eating soup cake in June is scientific.
In addition to hot noodle soup, you can also eat water in the dog days. Pass the cooked noodles out with cold water, mix with garlic puree, and pour with brine. It will not only stimulate appetite, but also 'lose heart fire'.
Fuli can also eat 'fried noodles'. The so-called fried noodles, is to use a pot to fry the flour to dry, stir fry, and then mix it with water and sugar. This kind of eating method has existed in Han Dynasty. In Tang and Song Dynasties, it was more common, but at that time, it was to fry the cooked wheat first, and then grind the pasta. Su Gong, a medical expert in the Tang Dynasty, said that fried noodles can "relieve the heat, stop the discharge and make the large intestine real"
