A good poem

There is a poem saying that the northwest looks at the hometown and the southeast sees the bright moon. According to relevant information, where is your hometown in the northwest? Seeing the Moon in Southeast China is from a seven-character poem written by Bai Juyi, a poet in Tang Dynasty. This poem expresses the different sighs of ancient and modern things in a comparative way. The first four sentences are contrast, and the last four sentences are lyrical.
