What is the content of the poem "Yellow Crane Tower Farewell Meng Haoran on the way to Yangzhou"?

The Yellow Crane Tower Farewell to Meng Haoran on the way to Yangzhou was written by Li Bai. The Yellow Crane Tower bid Meng Haoran farewell to Yangzhou, and the fireworks went down to Yangzhou in March. My friend's sail shadow faded away and disappeared at the end of the blue sky, only seeing the first line of the Yangtze River and heading for the distant horizon.

The main idea of the poem is that someone said goodbye to me at the Yellow Crane Tower, like catkins in smoke and flowers in spring, and went to Yangzhou for a long trip in March. The sail shadow of the lonely boat gradually disappeared at the end of the blue sky, only to see the Yangtze River rolling into the sky.

The first sentence of this poem is farewell at the Yellow Crane Tower, where two poets often get together, adding a pleasant atmosphere. In the second sentence, the fireworks in March not only reproduce the charming scenery of the bustling place in spring and March, but also reveal the flavor of the times. While writing the scenery, the translation of lyrics has disappeared. However, Li Bai was still looking forward to it before he noticed that a spring river was flowing in the distance. Li Bai's deep affection for his friends and his yearning are all reflected in the poetic wooden pillar of Shenchi. The poet's mood is ups and downs, just like a stream of spring water rolling eastward. In short, this poetic parting is vividly expressed by the poet with gorgeous spring scenery and March scenery, with the broad picture of boating on the Yangtze River, and with the details of overlooking the lonely sail.
