The river just shows its sharp corners. What season did dragonflies stand in a long time ago?

1, May 5th is the long summer among the 24 solar terms. This is the first solar term in summer, marking the official start of the season in Xia Meng. "Since then, everything has grown, hence the name Long Summer."

2. There are three classes in the long summer: "First class: sound; Second, earthworms come out; Third, Wang Guasheng. " This means that in this solar term, you can first hear crickets chirping in the field, then you can see earthworms digging, and then the vines of melon begin to climb and grow rapidly. Spring competes for the sun, and summer competes for time. When the temperature rises obviously and crops enter the peak season, people are used to treating the long summer as an important solar term. Crops should be harvested as soon as possible. After the long summer, the sunshine gets longer and the temperature gets higher. In addition, rain will come sooner or later, and the rainfall is closely related to the future harvest. Therefore, there is a saying in agricultural proverbs that "see summer in the long summer".
