Farewell to Meng Haoran on the way from Yellow Crane Tower to Yangzhou is a farewell poem. Since it is a farewell poem, the poet is bound to pour his feelings for his friends into it. Judging from the conception style of The Yellow Crane Tower Farewell to Meng Haoran's trip to Yangzhou, its emotional expression undoubtedly falls on the action. In the spring of March, Meng Haoran fled his hometown and came to Wuchang, where he was invited to meet Li Bai at the Yellow Crane Tower. After some binge drinking, Li Bai tried to send Meng Haoran down the river, but he politely refused. Therefore, Li Bai had to go upstairs and stare for a long time, watching the "lonely sail" carrying his friend Meng Haoran go away and sing a farewell song. Therefore, "sailing alone, the blue sky is exhausted" is the poetic eye of this poem.
