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.

Haze pervades the vast cold river, and the bright moon shines on 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.

1, the creative background of Bo Qinhuai

Du Mu was very concerned about politics in his early days, and he was worried about the riddled Tang Dynasty. The poet stayed at the Qinhuai River overnight, saw the colorful lights, heard the obscene songs and songs, touched the scene, and was deeply moved by the thought of the decline of the Tang Dynasty and the fatuity and debauchery of those in power. He wrote this song "Bo Qinhuai".

2. Appreciation of Bo Qinhuai

The first sentence of this poem is extraordinary, and the word "cage" is eye-catching. Smoke, water, moon and sand are harmoniously combined by the word "cage", depicting an extremely elegant night by the water. It is so soft and quiet, but it also implies a slightly erratic state of mind. Pen and ink is so light, but it is so ethereal and cold.

The "moonlight and water moon" in the first sentence is related to the "staying at Qinhuai" in the second sentence, so after reading the first sentence, it is naturally "staying at Qinhuai near the restaurant". However, as far as the poet's activities are concerned, you must have a "night berth at Qinhuai" before you can see the scenery of "a cage of misty water and cold moon sand", but if you really look down, you will find that the flat plate is tasteless.

The advantages of this way of writing poetry are as follows: firstly, it creates a very distinct environmental atmosphere, gives people a strong attraction, and creates an artistic effect that affects the whole body and meets the requirements of artistic expression. When people appreciate a painting, they usually pay attention to the wonderful picture first, and then look at the inscription in the corner. Therefore, the poet's writing style is quite in line with people's artistic appreciation habits.
