Drink a bowl of homesick wine alone, indulge in wine, and spend a night alone; I am alone in a foreign land, missing my hometown by drinking, relieving my worries by alcohol, and wandering alone at night. "Homesick wine" represents deep sadness, "pouring sorrow" relieves sadness, and "long night" is a long night. Therefore, if a person drinks a bowl of homesickness wine to drown his sorrows, it is equivalent to a lonely night; I am alone in a foreign land, missing my hometown by drinking, relieving my worries by alcohol, and wandering alone at night.
