Let's talk about the beauty of geese crossing the south, and write about the scenery when the wind from the north comes to cool down.

"Wild geese fly south, the north wind comes to Shui Han", these two sentences are scenery writing.

The author captured the typical things at that time and pointed out the seasons.

The leaves on the tree gradually fall off, and the geese fly south. This is the most representative autumn scenery.

But autumn alone can't show "cold". The author makes people feel cold by whistling in the north wind, and points out the "early cold" in the title.
