From the Song of Mujiang by Bai Juyi, a poet in the Tang Dynasty, the whole poem is as follows:
A sunset gradually sank into the river, half green and half green.
The loveliest thing is the ninth day of September. The bright pearl's bright crescent moon is shaped like a bow.
Translation:
A sunset gradually sank into the river, and the river was half green and half brilliant red.
The loveliest thing is the night on the third day of September, with dew like beads and crescent like a bow.
