"We know each other far and near, but Wan Li is still a neighbor" comes from "Seeing Li Shaofu in Weicheng" written by Zhang Jiuling, a poet in Tang Dynasty. It means that close friends and confidants, regardless of distance, are separated from Wan Li as neighbors. This poem expresses the profound friendship between the poet and his friends, as well as their real feelings of missing each other. Through this poem, the poet expresses his feelings without too many words. As long as he is soul mate, he can feel each other's warmth and care even though he is separated from Wan Li.
