What does the poem "September is poor in the middle of the night, dew is like a pearl, and the moon is like a bow" mean?

This poem was written by the poet when he volunteered to go abroad to avoid the disputes between the DPRK and China. The whole poem expresses the poet's lonely mood. The analysis is as follows: if this poem is simply regarded as a simple landscape poem describing the poet facing the autumn sunshine, then this poem is too ordinary. How can it be said to be a masterpiece through the ages? A great god is a great god. Just adding the word "poor" to an ordinary landscape poem makes an ordinary landscape poem extraordinary and immortal. The sunset in the poem is covered with water, rippling with light waves, revealing like pearls and crescent moons like hooks. The seemingly simple scenery, but under the embellishment of a word "poor", the whole poem shines. The word "poverty" is the reference and key to the artistic conception of poetry, and the whole poem takes it as the center. Therefore, the word "rustling" in the poem "Half-River Rustling and Half-River Red" doesn't mean blue waves at all, let alone green, but it means "bleak" or "cold". The meaning of "red" in "Half-River Red" is not red, but warm. The whole poem is translated as follows: a touch of sunset shines on the water, half of the river is a cold lake, and half of the river is a warm lake. On this autumn night on the third day of September, in the face of the cold dew and the bow-shaped scenery of the waning moon, how can we not feel chilly? If "rustling" is understood as "gurgling" or "green", how to explain the word "pity"? Isn't this gilding the lily?
