In the past, there was a folk custom of "eating new things in summer", that is, after the summer heat, farmers tasted new rice, ground the newly cut rice into rice, and prepared to worship the food of the five grain gods and ancestors, and then everyone tasted new wine. It is said that "eating new things" means "eating new things", which is the first new day after the summer festival. Cities generally buy a small amount of new rice for cooking in old rice, plus newly listed vegetables. Therefore, there is a folk saying that millet is eaten in summer and grain is eaten in summer.

2. In the dog days, there is a saying among the people that "radish falls in two volts, buckwheat can grow in three volts" and "jiaozi falls in one head, and pancakes spread eggs in three volts".

Eating jiaozi on the head is a traditional custom. Fukui people have poor appetite and are often thinner than usual, which is called bitter summer. In traditional customs, jiaozi is a food to stimulate appetite. Some places in Shandong eat raw cucumbers and boiled eggs to cure the bitter summer, and eat eggs in the morning without eating other foods. People in Xuzhou eat mutton when crouching, which is called "eating sheep". This custom can be traced back to the Yao and Shun period. There is a folk saying that "a bowl of soup in Pengcheng squats sheep without a doctor's prescription". People in Xuzhou love Fuyang, which is nothing more than a local folk song "Pick up girls on June 6th and make new wheat cake mutton soup".
