Why does Xiao Shu eat jiaozi?

The reason why we eat jiaozi in the heat is because it is the tenth day after the heat, and there is a folk saying that jiaozi is the first to fall, and the second to fall. People in summer are often thinner than usual, commonly known as bitter summer, and jiaozi is a traditional food to stimulate appetite and relieve hunger.

Summer is the eleventh of the twenty-four solar terms, at the end of the afternoon and the beginning of the month. The sun reaches longitude 105 degrees, and the festival is held on July 6-8 of the Gregorian calendar every year. Summer means hot, a little hot, not very hot. It's getting hotter, but it's not the hottest. Although light summer is not the hottest season in a year, it is followed by the hottest solar term in a year. There is a folk saying that "it is hot in summer and hot in summer, and it is steamed and cooked".
