Because in March of the 18th year of Kaiyuan (730), Li Bai learned that Meng Haoran was going to Guangling (now Yangzhou, Jiangsu), so he sent a letter to meet Meng Haoran in Jiangxia (now Wuchang District, Wuhan).
A few days later, Meng Haoran left by boat and Li Bai personally sent it to the river. When I was leaving, I wrote this song "Farewell to Meng Haoran on the way to Yangzhou by the Yellow Crane Tower".

Yellow Crane Tower —— Meng Haoran's farewell on his way to Yangzhou
Author: Li Bai
My old friend resigned from the Yellow Crane Tower,
Fireworks fell in Yangzhou in March.
Lonely sails, distant shadows, blue sky,
Only the Yangtze River flows in the sky.
Translation:
Best friend Meng Haoran bid farewell to the Yellow Crane Tower.
In late spring and March this year, he will go east to Yangzhou.
He disappeared into the shadow of a boat with the blue sky,
I saw the Yangtze River rolling towards the horizon.
