What is autumn like in ancient poetry?

In Baipu Village, Western jackdaw in the west, there is an old tree with light smoke, a little Fei Ying, green mountains and green waters, white grass, red leaves and yellow flowers.

This song expresses the author's positive, optimistic and cheerful attitude towards life and thoughts and feelings. It's really called "don't be happy with things, don't be sad with yourself." Although the title is "Autumn" and it is full of autumn meaning, I can't find a word "Autumn". Draw a picture of autumn dusk at the beginning to create a quiet and lonely atmosphere, and then select a typical autumn scene in the form of noun juxtaposition.
