What scenery did the poet of At Nanjing Ferry describe and express?

There is a small building at Jinling Ferry near Zhenjiang. Travelers who spend the night can't sleep all night, and their hearts are full of homesickness. As the sun sets, the river tide has just receded. When will the lights flash across the other side, which may illuminate Guazhou on the other side? This is a poem written by a poet when he wandered in the south of the Yangtze River. When Zhang Hu spent the night at Zhenjiang Ferry, he faced the night view of the Yangtze River, and used this poem to express his sadness on the journey and his loneliness and desolation. The language of the whole poem is simple and natural, and the picturesque night scene on the river is described as quiet and melancholy, elegant and fresh. "Jinling Mountain Building" refers to "Jinling Crossing" in Zhenjiang, not Nanjing. Let's get down to business. The word "ke" is used lightly and appropriately, and "ke" is interpreted as "he", which is easier than "he". These two sentences are the introduction, which is straightforward and easy to write, and then naturally leads readers to a good place. "The tide falls on the river at night," and the poet stands on the hill and looks at the river at night. Echoing the previous sentence "one night", it secretly revealed that the traveler did not fall asleep that night. So this sentence and the second sentence are naturally connected. The poet's pen is light and delicate, and in the meticulous carving, there is no axe mark, which seems to be integrated. The night river at low tide is immersed in the light of the slanting moon. With the cold water in the smoke cage as the background, I suddenly saw sparks flashing in the distance, and the poet couldn't help singing: this wonderful painting of the night river has also been completed. Just look at the "fire of two or three stars", how ethereal the pen is, and it doesn't need much touching feelings. "Two or three" is enough. "One inch and two inches of fish, three poles and two bamboo poles" is a lot, but it is also a real scene. The "23 Sparks" are dotted on the hazy night river on the slanting moon, which is particularly bright. These three words also contain the poet's surprise and lament, conveying a distant artistic conception. The realm of this poem is beautiful and quiet. The two three-star fires and the light and shade of the slanting moon and the night river set each other off, blending into one, like a light ink landscape painting.
