"The Soul of Poetry: The Biography of Yang Zai" is a masterpiece spanning time and space with the Yuan Dynasty poet Yang Zai as the protagonist, integrating history, science fiction and philosophy. The whole book runs through the civilizational context from the Song and Yuan Dynasties to the interstellar era, with "poetry inheritance" as the main line, showing Yang Zai's multi-dimensional life trajectory as a poet, scholar, official and cultural inheritor. The work breaks through the boundaries of traditional biography, combines dual-line narrative and virtual and real techniques, reconstructs the cultural history of the Yuan Dynasty, and explores the survival and innovation of Chinese civilization in a cross-national, cross-era and even cross-interstellar context. It not only reshapes the historical image of Yang Zai, but also uses poetry as a medium to ask about the future possibilities of the eternity of civilization and the integration of humanities and science and technology. It is a pioneering literary and cultural thought experiment.
