Just look at the calendar. Why will there be a summer vacation after beginning of autumn? What do you mean by summer vacation?

Because when I was in beginning of autumn, it was still in the "dog days" period, and the weather would still be hot, and it didn't really end until after the summer heat, and the weather turned cold, and it really entered the "autumn" in the climate sense. The "location" of daylight saving time means termination and end, and daylight saving time means that the hot summer is over.

Beginning of autumn is from August 7th to 9th every year. In China, except those places with high altitude in the north latitude, beginning of autumn is still in the hot summer, and even in most parts of the northeast, there is no autumn scenery with cool breeze and yellow leaves fluttering.

The summer solar term is around August 23rd in Gregorian calendar, and the sun reaches 150. Summer solar terms mean entering the autumn with meteorological significance. After the summer, the temperature in the area north of the Yangtze River in China gradually drops. Summer is a solar term reflecting the temperature change. By this festival, the summer heat is fading and the coolness is getting longer. There are folk sayings such as "it's cool in autumn and hot in summer" and "the heat will not come".
