The origin and custom of solar terms in midsummer. How did the summer heat come from?

1, "Twenty-four solar terms": "June Festival ... it is hot in summer, and the heat is also divided into different sizes. It is small at the beginning of the month and big in the month, but it is still small today." Summer is hot. The ancients thought that the summer heat period was not the hottest time of the year, so it was called summer heat.

There was a custom of "eating new things" in the past summer. "Fresh food" means grinding new dozen rice and wheat into powder, making all kinds of cakes and noodles, which are shared by neighbors and villagers to express their desire for a bumper harvest. At the same time, these new goods should also prepare a sacrifice for their ancestors, and please bless the good weather.
