Chanting willow is a seven-character quatrain written by He, a poet in the prosperous Tang Dynasty. This poem is a poem about objects. The first two sentences of this poem use two new metaphors of beauty to describe the vitality and prosperity of spring willow; The latter two sentences compare the spring breeze to "scissors" more ingeniously, and show the invisible "spring breeze" vividly, which is not only novel in concept, but also full of charm.
