The document discusses the poem "Farewell" written in 1915 by the Buddhist monk and artist Hong Yi. The poem expresses sadness at parting with a friend, describing the green grass stretching to the sky, the lingering sounds of a flute and willows rustled by the evening breeze, and distant mountains beneath the setting sun. It evokes parting is like being at the edge of heaven and earth, with bosom friends now half gone.
