What images do Bai Juyi's poems describe in the late autumn night? What kind of artistic conception have you created?

Blue sky, moonlight, melancholy, lonely shadows, residual chrysanthemums, hedges, decaying tung leaves, cold wells, saihong, crows, eternal nights, wind and white dew.

In the blue sky, there is a bright moon hanging high, bright and beautiful, silent. In the faint moonlight, the shadow of a person under the moon is more lonely, as if hanging up.

Flowers bloom, and the withered chrysanthemum leans against the withered plane tree under the sparse fence leaves and falls into the cold well.

Hong Fei, beyond the Great Wall, in order to avoid the attack of cold current, flew across the sky rapidly, from north to south, feeling that late autumn has passed; Because the days are short and the nights are long, the neighbors' crowing is delayed.

I spoke without emotion, thinking in vain, and the wind blew off my wet skirt, and I felt a chill.
