I am sleeping soundly on an empty cup, and dreaming of Jiangnan means that all my longings and fantasies about Jiangnan may come from a misty dream. In the dream, the afterglow shines on the lotus pond, the floating fragrance wraps around the curved bank, and the round shadow covers the flower pond; the oars make a gentle sound, and the slow boat rocks the time. Jiangnan is a Chinese geographical region concept. In the broad sense, Jiangnan generally refers to the south of the Yangtze River. In the narrow sense, Jiangnan generally refers to the area south of the middle and lower reaches of the Yangtze River.
