What role does Yan Geling's poems play in describing autumn scenery and weather?

The autumn wind is bleak, the weather is cool, the vegetation is shaking and the frost is exposed, and the flocks of birds leave Nanxiang.

I miss you and your guests, and my heart breaks. I miss my hometown, so why did you send it to stay for a long time?

I am alone in my room, afraid of forgetting my worries, and I don't feel tears on my clothes.

Help the piano to sing strings and send them to Qing merchants.

Short songs cannot be long.

The moon shines on my bed,

"The autumn wind is bleak, the weather is cool, the vegetation is like frost, and the geese go south." The first three sentences are about a chilling scene in late autumn, preparing for the heroine's appearance. The image here is visual, auditory and sensory, giving people a feeling of emptiness, loneliness and decline. This scene is consistent with the inner feelings of the upcoming heroine. Although these three sentences are just scenery, there is no positive love, but we already feel that love is full of paper. This method of expressing feelings of parting and nostalgia by describing autumn scenery is a tradition in China.
