By reading Xizhou Qu and Mulan Poetry, we can understand the differences of poetic styles between the North and the South during the Southern and Northern Dynasties.

From the content point of view, the Western Zhou Opera in the Southern Dynasties takes the love of men and women as the theme, which is fresh and graceful, with the life breath of young men and women in villages and towns in the south of the Yangtze River, and shows the feminine temperament of the people in the south. The northern folk song Mulan Ci tells the story of Mulan's father joining the army, which is more realistic. Mulan is simple and has the masculinity of a man. It is a typical style of northern minorities, good at riding and shooting, and the concept of men and women is not as conservative as that of the south. The poems of the Northern Dynasties did not focus on the topic of love, but were broader. This is because the northern environment has created the rough and bold style of northern folk songs, while the water in the south of the Yangtze River has created the children in the south of the Yangtze River fresh and elegant, gentle and graceful. From a technical point of view. Mulan's poems are full of intertextuality and authenticity, which shows the rough national style of the northern nationalities and also reflects the open living habits and concepts of men and women in the northern nationalities. For example, Yang Dayan's wife can ride a horse and shoot, and her life is relatively free. However, the Western Zhou Dynasty songs in the Southern Dynasties are mostly puns, graceful and fresh, which show us the unique feelings of Jiangnan children in the South.
