Twenty-four solar terms, section 11 gas

Slight summer heat, the eleventh solar term in the twenty-four solar terms, is the end of the afternoon month of the dry calendar and the beginning of the last month. When the sun reaches longitude 105 degrees, it will meet on July 6-8 of the Gregorian calendar every year. Summer means hot, summer means less hot, not very hot. Although the summer heat is not the hottest season in a year, it is followed by the hottest solar terms and summer heat in a year. There is a folk saying that "summer heat is hot, steaming is cooking". Many places in China have entered the season with the most thunderstorms since summer.

The day when the hot summer begins to enter the midsummer is also called "hot summer day". Summer days usually occur between summer heat and summer heat, and it is the time with the highest temperature and the heaviest damp heat in a year. Monsoon climate is the main feature of China climate. In summer, affected by warm and humid air currents from the ocean, many places in China are hot, humid and rainy. Although the sun is fierce, the temperature is high and it is wet and rainy in hot summer, for crops, the same period of rain and heat is beneficial to growth.

In the past, in the south of China, there was a folk custom of eating new rice in hot summer, that is, after the hot summer, farmers ground the newly cut rice into rice, prepared a meal to sacrifice to the grain gods and ancestors, and then everyone tasted new wine. [15] In the northern region, there was the earliest tradition of eating jiaozi. The second person who has no appetite is often thinner than the first one, which is commonly known as bitter summer. In traditional customs, jiaozi is an appetizer, and jiaozi looks like an ingot, which means "Fu Bao, Yuan Bao". Eating jiaozi symbolizes full blessing.
