The poet expressed his happy mood after being pardoned.
"Early Departure from Baidi City" is a poem composed by the great poet Li Bai of the Tang Dynasty when he was pardoned and returned from exile. It is one of the most widely circulated poems among Li Bai's poems. In the second year of Qianyuan (759) of Emperor Suzong of the Tang Dynasty, the poet was exiled to Yelang. When he was pardoned by Emperor Bai, he wrote this poem when he returned to Jiangling by boat. The poem is about describing the section of the Yangtze River from Baidi to Jiangling, where the water flows rapidly and the boat moves like flying. The first sentence describes the height of Baidi City; the second sentence describes the distance to Jiangling and the speed of the boat; the third sentence uses the shadow of the mountain to highlight the speed of the boat; the fourth sentence writes that the boat is as light as nothing, indicating that the water is flowing like water. The poet combines the happy mood after being pardoned with the magnificence and beauty of the country and the smoothness and briskness of the boat along the current to express it.
The whole poem is full of exaggeration and fantasy. It is written in a smooth and elegant way, shocking the world, but it is not artificial, it is arbitrary and natural.
