1, there is a folk saying that "jiaozi lies in the first place, and eggs are spread on pancakes in the second place". The dog days are the season with the highest temperature and humidity in a year, which can be divided into the first, middle and last days. People will treat themselves with some good meals that are "different from usual" in dog days, which is called "sticking to the fat". At that time, jiaozi, noodles, pancakes and eggs were all delicious. The origin of eating jiaozi on one's head is that it is a traditional custom to eat jiaozi on one's head in the north, because on rainy days, people's appetite is bad and they can't eat anything, and jiaozi is the food to satisfy their appetite in the traditional customs of China people. Eating jiaozi on the head has the meaning of "Yuan Bao Fu", because jiaozi is shaped like an ingot, and "Fu" is homophonic with "Fu". Moreover, dumpling stuffing is generally finely chopped and easy to digest. Therefore, people eat jiaozi on their heads, hoping to spend the summer safely.

2. In the Southern Dynasties, Liang Zonggu's Chronicle of Jingchu's Years, he said: "There is a soup cake with a solar eclipse in June, which is called evil." May is an evil month, and June also touches the edge of the evil month, so it should also be "evil". This should be a superstition.

3. Erfu noodles means that when you are in midsection, it is recommended to eat pasta. This is because the temperature in summer is high, people sweat a lot, and protein and amino acids are easy to lose. Therefore, you can eat more pasta appropriately to supplement these substances. In dog days, you can not only drink hot noodle soup, but also eat water. Boil the cooked noodles with cold water, mix with garlic paste and pour with halogen seeds, which not only stimulates appetite, but also "defeats the heart." Eating noodle soup in June and sweating can drive away the disease, which is still scientifically justified.
