The first two sentences of Uptown create a lonely atmosphere in the dead of night, and the moonlight hangs on the tree, paving the way for the appearance of you and peace. "Leak" refers to the clepsydra used by the ancients for timing; "Leak" means late at night. These two writers are extraordinary, rendering a state of being born alone. In the next two sentences, first of all, I pointed out the image of a lonely person with many worries, and then the image of the lonely person flew from the lonely person to the lonely person, which made the two images correspond to each other and fit each other, making people think: Isn't the lonely mood of the lonely person just like the shadow of the lonely person? These two sentences are not only true writing, but also through the correspondence and grafting of human and bird images, which greatly strengthens the transcendence of "wandering" and has symbolic significance and poetic beauty.
