This poem came from the Tang Dynasty poet Wang Wei's "Autumn Dusk in the Mountains": I can't see anyone in the empty mountain, but I can hear people talking. Back into the deep forest, the light shines on the moss again. Among them,'pear blossoms fall all over Nanshan' was one of the last two sentences. This poem described how the poet strolled in the mountains and saw the scene of pear blossoms falling. It described the beauty and tranquility of the pear blossoms. In literature, this poem was often used to describe the beauty of nature and to sigh at the tranquility of the environment.
