Xiaoshu, the eleventh solar term of the 24 solar terms, is paid on July 6-8 of the Gregorian calendar every year. Although the light heat is not the hottest season of the year, it is followed by the hottest solar term in the year, which is known as "light heat and heavy heat, steaming at the top and boiling at the bottom". In many parts of China, thunderstorms are the most frequent in the summer. Sunstroke begins to enter the dog days, so called "heat" In the "three volt" days, the three volt days usually occur between the light summer heat and the first summer heat, which is the highest temperature, humid and sultry period of the year.
In the past, people in southern China had the custom of "eating new food" during the summer heat, that is, after the summer heat, they tasted new rice, and farmers milled the newly cut rice into rice, prepared food to worship the grain god and ancestors, and then everyone ate new wine. In the northern region, there is a tradition of eating dumplings. People have a poor appetite and are often thinner than usual. It is popularly known as the bitter summer. In traditional customs, dumplings are food for appetizing appetites and appetizers. In addition, the appearance of dumplings is like yuan bao, which means "yuan bao cang fu". Eating dumplings symbolizes full happiness.
