Abstract:In the fieldwork on heterogeneous culturesꎬ Yi poet Aku Wuwu guarantees the rich connotation and authenticity of his ethnographic research object through broad vision and parallel perspective. In the collection of poems Coyote Traces created in his sojourn in Americaꎬ he wrote a large number of poems related to Native American′s mythsꎬ history and be ̄ liefs. These poems are not only the artistic crystallization of the poet′s emotions inspired by his fieldwork in foreign cul ̄ turesꎬ but also an in-depth description and faithful record of Native American culture. Coyote Traces creatively realized the combination of ethnography and poetryꎬ using poetry as the " esperanto" ꎬ which played an important role in deepening the world′s understanding about Native Americans and promoting cultural exchanges and mutual learning among different na ̄ tions.
