What are the Mid-Autumn Festival images in ancient poetry? What do you mean? What else is there besides the feeling of sad autumn?

1, autumn crisp

The empty mountains are bathed in a new rain, and feel the early autumn at night.

2. Harvest, fruitful.

Sow a seed in spring and reap ten thousand tons of millet in autumn.

3, fallen leaves return to their roots, homesick

Cong Ju shed tears the other day. She was alone in the boat. -Du Fu's "Eight Poems of Autumn Prosperity"
