What are the characteristics of the literary and artistic forms of the Song Dynasty

There were many characteristics in the forms of literature and art in the Song Dynasty, among which the most prominent was the phenomenon of "cultural assimilation". "Assimilation of literature" referred to the Song Dynasty writers integrating their thoughts, feelings, and style into their works to form a unified literary style. This style was widely used in the literary works of the Song Dynasty, such as the works of Su Shi, Xin Qiji, Li Qingzhao and other writers, all showing unique personalities and styles. Another important feature of the Song Dynasty's literature and art was its emphasis on leisure. In the Song Dynasty, people generally believed that leisure was a noble quality. Many writers expressed their yearning for leisure life in their works. For example, in Su Shi's "Ode to the Red Cliff", it was written that "leisure time is good for learning", which showed the respect for academic research in the literature of the Song Dynasty. In addition, the literature and art of the Song Dynasty also had unique characteristics in terms of language. For example, slang, idioms, and proverb were commonly used in the poems of the Song Dynasty. These rich and colorful language forms made the works more lively and interesting. The literature and art of Song Dynasty embodied the dual characteristics of "cultural assimilation" and "leisure" in the form of expression, which provided important reference and enlightenment for the literary creation of later generations.
