Understand the main idea of this poem. After singing the farewell song, you untie the boat far away. There are green hills on both sides, full of red leaves, and the water is rushing eastward. It was getting late that day, and when I woke up, I realized that people had left. It's raining all over the sky at this time, and I'm the only one walking down the west building alone! The second sentence of this poem is a description of the scenery. In writing, we can see the combination of dynamic and static, and render the atmosphere of parting. In the last two sentences, when writing "Sunset", the sad scene of "the city is full of storms" can be considered as the sadness caused by "people in the distance", and the meaning is correct, but you must answer according to the category and general idea of the poem.
I hope it helps you.
