"Sailing alone in the sky, I can see the Yangtze River flowing in the sky." The last two sentences of the poem look like landscape writing, but there is a poetic detail in landscape writing. Li Bai has been sending his friends to the boat, and the boat has already left, while he is still watching the sails in the distance by the river. Li Bai's eyes looked at the sail shadow until it gradually blurred and disappeared at the end of the blue sky, showing a long time to watch. The shadow of the sail has disappeared, but Li Bai is still staring at it. At this time, he noticed that a river with spring water is flowing far to the junction of water and sky.
"Just watching the Yangtze River flowing in the sky" is the scene in front of us, not just writing about the scenery. Li Bai's deep affection and yearning for his friends are all reflected in this poetic style. The poet's heart rises and falls, just like a stream of spring water rolling eastward. In a word, this poetic parting of two romantic and chic poets is another yearning parting of Li Bai, which vividly shows the vast picture of boating on the Yangtze River and the details of lonely sails in the distance with the gorgeous scenery in March.
