英文摘要：

Bimo culture is the traditional culture of Yi people.It is generally handed down and spread by Bimo,the native ritual practitioner whose duty is to take charge of Yi’s traditional folk conventions and religious activity.In Yi’s traditional culture,Suozhai(suni)mainly takes care of sacrifice-offering,praying,assisting,guiding and calling back the soul of the dead,while Bimo is in charge of chanting Yi’s recorded texts in offering a sacrifice to ancestors,guiding road for the dead,practicing magic,curing the sickness and so on.Being the major carrier of Yi’s traditional culture,Bimo culture developed from Suozhai(suni)culture,a representative of native religious culture derived from prehistoric age.Bimo culture is a synthetical agent of Yi’s oral culture and written scriptures.This essay preliminary analyses the developmental periods,principal substance of Bimo culture,and Yi’s historical science.The author thinks that Bimo culture not only provides important literate evidence for different periods in Yi’s history,fills in the natural science gaps,concerning astronomy and calendar,tools of production,agriculture,handicraft,and medical science,but also offers valuable data for Yi’s ancient social and political system,ethnic relationship,in particular,between ethnic groups of Yi language family.The author,in conclusion,points out some of the drawbacks and insufficiencies emerged from behind Bimo culture.
