The summer solstice is not the first day of the ambush. The third Geng day after the summer solstice is the time of the ambush.

According to the provisions of the almanac: "The number of volts will start at the third Geng day of the summer solstice", which means that counting from the summer solstice to the next, the volts will begin to fall on the third "Geng day". One Geng day 10 days.

The "Geng Day" here refers to the day with the prefix "Geng" in the ancient "Stem and Branch Day Calendar". The almanac also stipulates that the first "Geng Day" after the "Liqiu" solar term is the day when the "Mofu" (i.e. the third volt) begins.

For example, the summer solstice in 2022 is June 21, which is "Yisi Day", and the first Geng Day after the summer solstice is June 26, which is "Gengxu Day" "In the future, every 10 days will be a Geng Day. Therefore, the second Geng Day after the summer solstice will be July 6, and this day will be the "Gengshen Day". The next 10 days will be postponed to July 16. One day is the third Geng day after the summer solstice. This day is also the time of entering the summer solstice, so it is called the "Geng Wu day". So this year the time of entering ambush is July 16th.

What to eat after entering Fu

Dumplings

In the north, there is a custom of "dumplings for the first time, noodles for the second time, and pancakes and eggs for the third time". It is a traditional custom to eat dumplings on the first day of the summer. People lose their appetite and tend to be thinner than usual on the first day of the summer. It is commonly known as the bitter summer. In traditional customs, dumplings are an appetizing food.

Chicken

A folk proverb goes: "Eating a chicken will keep you in good health for a year." In Nanchang, "Chicken is eaten in Toufu and duck is eaten in Toufu". Hunan and Jiangxi are adjacent, and chicken is also eaten in Toufu. Relatively speaking, there is some scientific basis for people in Jiangxi and Hunan to eat chicken during the dog days to maintain their health. During the dog days of summer, people consume a lot of physical energy and must supplement their nutrition appropriately.
