Function: Take the wandering Yang Hua and Zigui who cry "It's better to go back", which contains the feeling of wandering and the hatred of separation. It is in line with the situation at that time and blends into the scene.
"I heard that Wang Changling moved to the left and Longbiao had this message" - Li Bai, the great poet of the Tang Dynasty
Original text
When the poplar flowers fell, the child cried, and I heard that the dragon Marked the Five Streams.
I send my sorrowful heart to the bright moon, and follow the wind to the west of the night.
Translation
At the time when the poplar flowers were falling and Zigui was crowing, I heard that you were demoted to the rank of Longbiao Lieutenant. Longbiao is a remote place that passes through Wuxi. I place my sad thoughts on the bright and warm moon, hoping that it will accompany you to the west of Yelang along with the wind.
Extended information:
The first sentence of this poem uses Bixing techniques to describe the scenery and the season, creating a desolate and sad atmosphere. The wandering poplar flowers alone in the scenery and the words "It's better to go back" contained the feeling of wandering and the hatred of separation. They fit the situation at that time and blended into the scene.
Li Bai used rich imagination to express like-minded friendship in the form of love between men and women, and gave the abstract "sorrowful heart" the attribute of things, so that it would follow the wind and the moon to the west of the night.
This poem expresses comfort and sympathy for Wang Changling's unrecognized talent.
