Summer, which means hot, is a little hot, not very hot. Although the 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 "the light summer is hot and the summer is hot, steaming on it and cooking on it". Many places in China have entered the season with the most thunderstorms since the summer heat.

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 sunshine is fierce, the temperature is high, the humidity is high and the rain is rainy in this season, for crops, the same period of rain and heat is conducive to growth.
In the past, in southern China, there was a folk custom of "eating new things" in the summer, that is, after the summer, the farmers tasted new rice, and after grinding the newly cut rice into rice, they prepared meals for worshipping the God of Grains and ancestors, and then everyone tasted new wine.
In the northern region, there is a tradition of eating jiaozi on the head. People in Furi lose appetite and tend to lose weight than usual, which is called bitter summer. In the traditional custom, jiaozi is the food to satisfy their appetite, and jiaozi looks like an ingot, which means "Yuan Treasure Fu". Eating jiaozi symbolizes a full blessing.
Phenological phenomenon
Wu Cheng, a scholar in Yuan Dynasty, edited twenty-four solar term. He divided the 24 solar terms into "seventy-two periods" according to the scenery around the Yellow River basin and the characteristics of the 24 solar terms, and each solar term was divided into three periods. The three phases of the summer heat are: "When the wind is warm; Second, wait for the cricket to live in the space; The third waiting eagle begins to crow. "
In the summer, there is no longer a cool breeze on the earth, but all the winds carry heat waves; The Book of Songs? In July, the words describing crickets are "July is in the wild, August is in Yu, September is in the house, and October crickets enter my bed."
The August mentioned in this article is the June of the summer calendar, that is, when the summer is short, because of the heat, crickets leave the field and go to the corner of the courtyard to escape the heat. In this solar term, the eagle moves in the cool high air because the ground temperature is too high.
