Bold school and graceful school are two major schools in Song Dynasty. Bold works are bold and unconstrained, full of lofty sentiments and ambitions, giving people a positive force. The representative poets are mainly Su Shi and Xin Qiji. Graceful and restrained works have beautiful and subtle language, lingering feelings, relaxed and lively artistic conception, deep parting sorrow or bitterness, fine carving and narrow subject matter. They often write about personal experiences, love between men and women, and occasionally write about the scenery, blending their feelings into the scenery. Representative poets are Liu Yong, Qin Guan and Li Qingzhao.
