From the perspective of image construction, "Jiangnan Rain" is not a simple description of weather. It has the unique warmth and lingering characteristics of the Jiangnan region. It is not only a poetic symbol of smoke cages and painted bridges, but is also often associated with separation and nostalgia, laying a hazy and melancholy tone for the poem. The "old court clothes" are the core emotional carrier. The folds on the clothes hide the past of the official career. The word "old" directly refers to the precipitation of time, which is a metaphor for the recollection of past identities, ambitions or the rise and fall of dynasties, allowing the rain of nature and the storms of life to form a clever intertext.
