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.
