Picking Wei". Use willows as a parting gift to express the inseparability, the inability to bear to see each other, and the reluctance to part. Willows are a symbol of spring. Willows swaying in spring always give people a sense of prosperity. "Breaking willows to say goodbye" contains the wish of "Spring is always here".

Chen Weisongs poem of the Qing Dynasty: "How many wicker sticks are left now? Wait for discounts and gifts." Not only will people feel sad when they see willows, but they will also be moved to leave when they hear the song "Folding Willows". Li Bais "Hearing the Flute in Luo City on a Spring Night": "When I hear the broken willows in this nocturne, who can't forget the love of my hometown?" In fact, the willow tree can have many symbolic meanings, and the ancients gave the willow tree various emotions, so it is reasonable to use the willow tree to express feelings.
