This poem is crazy, and its realm is extremely lonely. The first two sentences can imply that one's mind is "tall" and fills the whole universe by slightly climbing "Southern Fight" and "Beichen". This poem is extremely interesting in psychology, and my heart is the universe. Then I looked up at the sky, and I couldn't find such a person anymore. Suddenly, the poetic scene depicts a sense of loneliness that transcends time and space. Looking at the endless emptiness of the "sky", "this person" seems so small. The whole poem is full of tension, depicting an image of a philosopher who is intoxicated alone under the starry sky.
