Jiangnan Spring is a seven-character quatrain written by Du Mu, a poet in the Tang Dynasty. This poem depicts the beautiful spring scenery in the south of the Yangtze River, reproduces the misty balcony scenery in the south of the Yangtze River, and makes the scenery in the south of the Yangtze River magical and confusing. At the same time, it is permeated with the poet's feelings about the rise and fall of history and his worries about the fate of the nation in the late Tang Dynasty.
