What solar terms are behind beginning of autumn?

Beginning of autumn is followed by a hot summer.

Summer is a solar term reflecting the temperature change. "Chu" means to hide and die, and "early summer" means that the hot summer has passed. "Twenty-four solar terms" said: "Go, go, the heat is over." "Chu" means termination, which means that the summer heat is about to pass, the summer heat will end on this day, and the temperature in most parts of China will gradually drop.

Being in summer is not only different from mild summer, severe summer, slight cold and severe cold, but also represents the transition from hot to cold.

In midsummer, the temperature enters a stage of significant change, and it drops day by day, and the summer heat is no longer threatening. This change in festivals is naturally reflected in farming.

A large number of practical proverbs left by the ancients, such as "One autumn rain and one cold", "Three rains in beginning of autumn, the flax fan hangs high", "It's cool in midsummer" and "Summer is coming", are all direct descriptions of climate change in the hot summer season. But in general, the climate in summer is characterized by hot in the daytime, cool in the morning and evening, large temperature difference between day and night, less precipitation and low air humidity.
