What is the picture depicted by the cold water and moon sand in the smoke cage?

The phrase "smoke cage, cold water, moon cage and sand" depicts the night scene along the Qinhuai River. Under the moonlight, the smog on the surface of Qinhuai River hangs over the cold river and the white beach. This poem outlines a hazy and cold water night scene, and the sad scenery just sets off the sadness in the poet's heart.

Bo Qinhuai's translation

On the smog-shrouded river, the cold Yue Hui was sprinkled in the white sand house. In the evening, I parked my boat by Qinhuai River, near the restaurant.

It seems that Jinling Genv doesn't know what the hatred of national subjugation is, but he is still singing the lewd song "Flowers in Yushu Back Garden" on the other side.

Smoke cage cold water moon cage sand, night parking near Qinhuai restaurant.

Strong women in business don't know how to hate their country, but they still sing backyard flowers across the river.

Bo Qinhuai's Creative Background

The author of "Bo Qinhuai" is Du Mu. When Du Mu spent the night in Qinhuai River, he saw the lively scene along the Qinhuai River, heard the obscene songs in his ear and was moved by the scene in front of him. I was deeply moved by the thought of the decline of the Tang Dynasty and the fatuity and debauchery of those in power, and wrote this song "Park Qinhuai".
