Businessman: refers to a singer who takes singing as his profession. "Across the River" sentence: Originally, it was said that Sui Jun soldiers had reached the north of the Yangtze River, and Chen Houzhu, a southern dynasty separated by a river, was still immersed in lewdness. The "Jiang" here refers to the Qinhuai River. Backyard flower: yushu backyard flower, according to legend, was a tune composed by the Southern Dynasties, and the Chen Dynasty perished in this decadent voice, so later people called it "the voice of national subjugation".
The singer didn't know the sadness of national subjugation, but still sang the song "Flowers in the Garden of Yushu" on the other side of Qinhuai River.
In the late Tang Dynasty, the river in the Tang Dynasty went from bad to worse, and the national situation became increasingly critical. However, the ruling bureaucrats and nobles were still living a life of ecstasy and singing and dancing. The author once stayed at Qinhuai River overnight, and heard that the singer was still singing the voice of national subjugation for the insensitive listener, which made the poet have the worry of history repeating itself. He was impressed by this scene and wrote this famous poem "Bo Qinhuai": "The smoke cage is full of sand in the cold moon, and the night is near Qinhuai Restaurant. Strong women in business do not know how to hate the country, but also sing backyard flowers across the river. "
The sentence "Businessmen and women don't know how to hate their country, but still sing flowers in the backyard across the river" integrates history and reality, which reminds people of the tragedy of Chen's death and the reality that the country was in danger in the late Tang Dynasty. It not only satirizes the upper class who are obsessed with money, but also expresses the author's patriotic feelings of focusing on national affairs.
