What does Mujiang mean by reciting ancient poems?

Full text: A setting sun is spreading in the water, and half of the river is rustling and half is red. The loveliest thing is the ninth day of September. The bright pearl's bright crescent moon is shaped like a bow.

A sunset 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.

Ode to Mujiang is a poem written by Bai Juyi, a poet in Tang Dynasty.

This is a masterpiece of landscape writing. The poet chose two groups of scenes from sunset to the rising of the new moon to describe them, used novel and ingenious metaphors to create a harmonious and peaceful artistic conception, and expressed his deep feelings and love for nature through chanting. The whole poem has beautiful and fluent language, fresh style, vivid, meticulous and true painting style, and its subtlety has always been praised.

Extended data:

There are three different "times" in Mujiang Song. Through the above analysis, the first two sentences of Ode to Mujiang were written before sunset (briefly) or at sunset; The last two sentences are mainly written after sunset (short time), that is, dusk; The last two sentences also lead to a period of time in the evening.

This is completely in line with the author's viewing order, that is, the author saw the sunset before sunset, the moon like a bow after sunset, and the dew like a real pearl at night. Most materials think that "the moon is like a bow" and "the dew is like a pearl" are seen by the author at the same time at night, writing in the sky before and writing underground after. In fact, this is because of the lack of common sense of astronomy and meteorology, ignoring the "time difference" between two natural phenomena.

As mentioned above, the author can only see "the third day of September" and "the moon is like a bow" shortly after sunset. At this time, because the sun has just set, the heat lost on the ground is not much, and the cool dew has not yet formed; By the time the night is "like a real pearl", the moon like a bow has sunk below the western horizon.
