What images did Li Yu use in his idle dreams?

Looking south, Li Yu

Dreaming in a distant place,

This is clear autumn in the south.

Thousands of miles away, the cool color is in the distance,

A boat is moored in the depths of reed flowers.

The flute is in the Moon Building.

[analysis]

This word is like an elegant ink painting. "National Wan Li" is the vision; The lake is full of reeds, and the boat is moored alone. This is a close-up view. Playing the flute under the moon is the main body of the picture. The boat is anchored in the depths of the reed flowers, reflecting freedom; Playing the flute on a moonlit night is melodious and full of romantic chic. "Autumn is sad and lonely since ancient times", this word praises autumn scenery in the south of the Yangtze River, because it is a memory of the captured ancestors of Song Dynasty, and compensates for the lost joy with the beautiful scenery in the dream. It means "I don't know that I am a guest in my dream, and I am greedy for joy in one day."
