What does summer mean? Explain.

Being in summer means that the hot summer is over.

First of all, the source of high temperature in summer:

The origin of the solar term "early summer" can be traced back to the book "Twenty-four solar terms" in ancient China. The book records: "If you go, you will go, and the summer heat will stop here." The meaning of "out" means "termination", which means that the hot summer is coming to an end, and the hot summer is coming to an end.

This solar term falls on August 23rd or 24th of the Gregorian calendar every year, when the sun reaches 150 degrees. Since then, summer vacation has become an important solar term in China's traditional culture, which has been in use ever since.

Second, the historical origin of the summer heat:

Shuo Wen Jie Zi says, "Stop." "Summer heat" means that the unbearable hot weather has ended and the summer heat has begun to fade. Both "three summers" and "three volts" represent hot and humid weather, and the curves on the time axis and the temperature axis are basically the same: summer is coming, summer is coming; When the sky falls, summer is over.

There are "three summers" in the 24 solar terms, namely, little summer, big summer and long summer, followed by early summer, heatstroke and late summer. There is also a "beginning of autumn" solar term in the middle of the "Three Summers". After beginning of autumn, it is summer, and the heat lasts for a long time. Long-term intense heat is beneficial to the growth and yield of crops. The ancients called the period from beginning of autumn to the autumnal equinox "long summer".
