On the mood of writing Li Bai's "The Beginning of Baidicheng"

The poet exiled Yelang, went to Bai Di for forgiveness, and returned to Jiangling by boat from time to time.

The four sentences in the whole poem are all condensed into one word "Liu", which reflects the refreshing mood of the poet after being forgiven. The morning light written with "clouds" turned into the beautiful scenery of sunshine at dusk. At this dawn moment, the poet bid farewell to Bai Di City with excitement and shouted "a thousand miles a day".
