What is the poem about the contrast between the sunset on the river and the color of the river?

Original poem:

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.

Author: Tang Bai Juyi

Translation:

In the evening, the setting sun is about to set, and it is gently scattered on the river. The river looks bright red under the setting sun, but the green waves are rolling on it. On the third day of September, what a beautiful night. Dewdrops on the grass stems and leaves on the shore are like rare pearls, and a crescent moon rises like a delicate bow.

Extended data:

This poem looks like a ginger landscape painting with fresh scenery and bright colors. In the poem, at dusk, the setting sun shines on the river, and the water surface reflects gorgeous brilliance. This is a common sight, and the poet feels novel because the river reflected by the sunset presents two completely different colors, half red and half clear, which form a strong contrast and are particularly beautiful. The author captured the characteristics of the scenery in time and accurately outlined the beauty of nature.

Whether the sun is setting or the new moon is first seen, people's colors are reflected on the river. The whole poem is written naturally by line drawing. The first two sentences are divided into two scenes, and there is no sense of separation. There is a natural artistic beauty, which gives readers an immersive feeling.
