After graduating from primary school, what are the poems and songs that are about to be separated from teachers and classmates and express their reluctant feelings when they leave?

Outside the Li Shutong Pavilion of Farewell, the ancient road is surrounded by green grass and the sky is blue. The evening breeze blows the flute, and the sunset is beyond the mountain. The days are short, and close friends are separated. Life is rare, only when you leave. The ancient road outside the museum is lush with green grass and the sky is blue. When will you come back here? Don't wander around when you come. The days are short, and all ends of the earth are friends.
