What holiday is summer vacation?

It is not enough to describe the summer solar terms from the end of August to the beginning of September simply by the beginning of temperature drop. Temperature drop is just one of the phenomena.

The reasons behind this phenomenon are as follows: first, the direct point of the sun continues to move southward, and the solar radiation weakens; Second, the subtropical high moved southward by leaps and bounds, and the Mongolian cold high began to itch to try, punching and kicking, showing its edge.

After summer, autumn is getting stronger, which is a good time for people to swim in the countryside to welcome autumn scenery.

After the heat, even the clouds in the sky seem to be evacuated and free, unlike the thick clouds in the heat. There has always been a saying among the people that "seeing a clever cloud in July and August" means "going out to welcome autumn".
